Daily News Compilation (HINDU) for 3rd April

The endless calamity in West Asia

Article is about Israel Palestine issue.

2014 - U.N.’s Year of Solidarity with the Palestinian People.
Why solidarity ? ---  Israel’s routine violation of international law and U.N. resolutions regarding Israel Palestine issue. Matters are so grave indeed that the Palestinians are no longer sure that they will retain the 22 per cent of historical Palestine that had been promised to them by the 1993 Oslo Accords.

Whats the reason behind Israel's routine violation of U.N. resolutions - US backing

The U.N. Special Rapporteur on Human Rights in the Palestinian Territories, Richard Falk
  • Israeli policy amounts to “segregation and apartheid,” including “continuing excessive use of force by Israeli security forces,” extra-judicial killings that “are part of acts carried out in order to maintain dominance over Palestinians” and a blockade of the Palestinian economy by the use of checkpoints and walls. 
  • The most striking part of Mr. Falk’s report is his assertion that Israel is conducting “ethnic cleansing” in the region. 
This report was put forward in UN and 5 resolutions were brought out for debate. But Israeli diplomats were absent because of labour strike and Israel's PM avoided all talk of Israeli policy and U.N. resolution.
Israeli Prime Minister Benjamin Netanyahu - all critics of Israel are anti-Semites. Israel is the only Jewish state.

U.N. agency, the Economic and Social Commission for Western Asia (ESCWA) in its new report, “Arab Integration: A 21st Century Development Imperative (2014),” the Commission notes, “Israel insists on being recognized by the world and the Arabs as an exclusively Jewish State. It imposes this recognition as a condition for reaching a settlement with the Palestinians. This policy is based on the concept of the religious or ethnic purity of States, which brought to humanity the worst crimes and atrocities of the twentieth century.” It is this idea of the Jewish State that fuels the toxic right-wing in Israel — they will not tolerate the return of Palestinian refugees or deliver full rights to Arab Israelis largely because they fear that this would demographically challenge their ability to create a Jewish democracy.

Reminding Israel that its definition of statehood has immense racial connotations has been a salutary task of the U.N. — it has also led to a backlash from the Netanyahu government, unwilling as it is to allow any criticism.

India and Israeli commerce
  • Currently, according to Israeli Defense Ministry data, India imports more than $1.5 billion of the $7 billion of weaponry that Israel exports. It is Israel’s most important customer.
  • India is currently looking at a bid from the Israeli firm Rafael for its Spike anti-tank guided missile. This contract will alone be worth $1 billion.
Ever since India and Israel established full diplomatic ties in 1992, India has cooled its political support for the Palestinians and heated up its imports of Israeli arms.

The arms deals themselves are not always advantageous to India:
  • A list of corruption scandals litters the court records in both Israel and India. 
  • India has exchanged its dependency on Russian military technology for a new dependency on U.S. and Israeli arms.
In March 2013, Prime Minister Manmohan Singh told the Shura Council in Saudi Arabia, “There is no issue more important for peace and stability in the region than the question of Palestine. Far too long the brave people of Palestine have been denied their just, legitimate and inalienable rights, including most of all the establishment of a sovereign, independent and viable Palestinian state.”

We purchase arms form Israel on one side and then say that Palestine issue is important and we support Palestinian people. This is due to two forces at work:
1. India needs arms from Israel.
2.  India’s reliance upon the Gulf Arabs(Palestinian supporter) for its oil.

To stem doubt about the relevance of the Palestinian cause that the U.N. has declared this the Year of Solidarity. 
There are two reasons why the current U.N. attempt is already more promising than earlier attempts. 
  • For one, the U.N. agencies themselves are much more aggressive about Israeli violations of U.N. resolutions and international law than previously. The tone of the reports and the statements by people like the U.N. High Commissioner for Human Rights, Navi Pillay suggest that U.S. protection notwithstanding, Israel is no longer to get preferential treatment. 
  • Second, a new public awareness of Israeli policies fuels the Boycott, Divestment and Sanctions (BDS) movement, whose Indian branch has begun to protest the participation of Indian artists in Israeli cultural fairs and Indo-Israeli business deals. 

Public purpose of architecture

Pritzker Architecture Prize
* most distinguished and celebrated award in architecture
* given to a professional in the field who has contributed substantially to humanity and displayed excellence in built work.

Awarded this year to Shigeru Ban
* built inexpensive, easily transportable and recyclable disaster relief structures across the world for two decades.
* His ingenious designs have converted cardboard, paper and other relatively inexpensive materials into useful and reliable building components. He has utilised them in challenging situations ranging from earthquake-disaster relief work in Bhuj to refugee structures in Rwanda. 

This year’s Pritzker Prize raises a key question for Indian architects and policymakers to reflect on: if good design brings in innovation and adds value, why are they not increasingly deployed to serve the public good?
In contrast, State departments in India pay hardly any attention to design. As a result, low-income housing projects impose unliveable environments on the poor, and cities are yet to see well-designed bus stops, easily maintainable public toilets and user-friendly civic buildings. Even the National Design Policy, announced in 2007, has not sufficiently focussed on socially useful products. 

The curious case of Neiphiu Rio

Neiphiu Rio: Nagaland Chief Minister to contest the coming Lok Sabha poll from the lone seat in Nagaland
Due to coalition politics becoming a norm of Indian political system, regional parties assume an important and decisive role in national politics. They became king-makers or prime minister-makers, which is why one sees so many leaders at the Centre plotting their return to their States and not the other way round.
So Rio’s decision to contest Lok Sabha election is a rare case and may be attributed to Naga national politics.

The tech edge to Africa’s first Islamic insurance for herders

In Kenya’s arid north pastoralists rely on livestock herds surviving boom and bust cycles of drought.
Takaful Insurance of Africa:  Africa’s first livestock insurance scheme to make payouts compliant with Islamic law, by bringing together Muslim scholars and number-crunching agricultural experts using NASA weather satellites.
 Unlike ordinary insurance schemes prohibited by Islam, takes only a management fee from clients.
Payments are assessed not according to the deaths of individual animals as it would be impossible to provide proof, but according to an index drawn up by experts at the Nairobi-based International Livestock Research Institute (ILRI), using satellites to measure vegetation coverage and thus the severity of drought.
Any surplus money after payments made is distributed equally among remaining policyholders.
Gyaan:
Such schemes can be recommended for India also.

The flexible working debate

Gateway Women: Started by Jody Day and gives voice to women who would like to have been mothers, but aren’t.
Now a survey of women aged between 28 and 40 confirms that a significant number — 54 per cent of a big sample — feel that childless women have to work longer hours than mothers.
There is also a pull-out quote from one respondent complaining that a “women friendly” workplace means just a mother-friendly one. 
The survey found that nearly half the women questioned agreed that women who worked flexibly were resented.

Voting while in the Army

A new vote bank of Armed Forces personnel is now looking a step closer to reality with the Supreme Court directing the Election Commission (EC) to allow defence personnel to vote as general voters in peace stations. 
The Representation of the People Act, 1950 defines the term ‘ordinarily resident’ in Section 20, a qualification required to get registered as a voter. Armed forces personnel are among the few categories of people defined as persons with ‘service qualification’ in Section 20(8) and are given a special dispensation in Section 20(3) and Section 20(5). This category can declare while living at a place ‘ordinarily resident’ status at another place where they would have normally lived, if it were not for the exigencies of service. Implicit faith was to be placed on their declaration and they would be registered at the place they indicated as their place of ordinary residence, most likely their native place, and as a corollary the place of their posting could not be their ordinary place of residence.
In a matter arising from the Nagaland Assembly Election in 1969, the court did not accept the argument that for service personnel, the place of posting cannot ipso facto be the place of residence.
The law gave a special dispensation to a service voter in that his declaration designating a place as his place of ordinary residence and certified by his organisation was not to be questioned by the Electoral Registration Officer (ERO) but simply accepted. It was intended to avoid the delay in registration if an enquiry were to be done independently by the ERO as in the case of ordinary voters.
Interpreting that judgment as mandating the registration of a service voter at the place of his posting and by cleverly using the provision u/s 20(5), a campaign was mounted in the run-up to the Punjab Assembly election in 2007 by Brig. H.S. Ghuman (retd.) and his All India Veteran’s Core Group (AIVCG) to have service personnel posted in several cantonment towns in Punjab to register as ordinary voters there.
Since then, retired service officers and others including a Member of Parliament have lent their support to this campaign culminating in the latest verdict of the Supreme Court. But as a note of caution that was sounded in many border States — that the local voter population may be small and can be outnumbered by the service personnel — the Court restricted the applicability of the order only to peace stations. In other words, only in peace stations can service persons claim they are ordinary residents and vote locally. 
If peace stations are defined in a location-specific manner, this can lead to anomalies. If Itanagar or Leh are defined as peace stations but not Tawang or Nubra, it may be kosher for vote bank politics but it will create disaffection among the local population in both places, given the small-sized constituencies and the thin margins of victory. Distinctions based on unit-specific roles in the same station will entitle men of the non-operational unit to register as voters and of the operational unit ineligible. So States have to be in either category to avoid anomalies.
As a larger number of service personnel would be in the many cantonments in Haryana and Punjab, competitive canvassing by politicians there can bring in its wake other problems.
A normal movement of a unit can be questioned by rival politicians as favouring one or the other candidate or party.
The formation commanders can be accused of favouritism as happened in the Punjab Assembly election in 2007. 
Since the new dispensation would not extend to all the defence personnel and since many service personnel may still remain registered in their native towns and villages by choice, the postal ballot system or its alternative — the proxy voting facility — would still be relevant.
Transmission time can be cut down if blank ballot papers are sent electronically, providing more time for their return. Better still would be to develop online voting and what better way than to provide it to the group that deserves it the most? We certainly owe it to our Armed forces personnel to do all that is possible to enable them to exercise their franchise.

IDFC, Bandhan get ‘in-principle’ nod to set up banks

The Reserve Bank of India (RBI), on Wednesday, granted ‘in-principle’ approval to two applicants, IDFC Limited and Kolkata-based Bandhan Financial Services Private Limited, to set up banks.
The RBI has also accepted the recommendation of the High-Level Advisory Committee (HLAC), set up by the RBI, to consider the application of the Department of Posts, separately in consultation with the Central Government.

Daily News Compilation (HINDU) for 2nd April

Poorly performing public services


Results of IHDS survey:

Right to Education
  • The implementation of the RTE should, in theory, lead to higher enrollment in government schools and better educational outcomes. Ironically we see the reverse. Private school enrollment increased from 28 to 35 per cent between 2005 and 2012 for children of 6-14 years.
  • small decline in reading and writing skills among children of 8-11 years. The decline higher for government schools.
NRHM
  • NRHM is supposed to strengthen preventive and curative care, particularly in rural areas and in States with poor health infrastructure. However, a very small proportion of the Indian population relies on public facilities. About 70 per cent of patients visit private providers — either as their first choice or once they are frustrated with public services. 
  • Ironically the greatest increase in the use of private services is in high-focus large States like U.P., Bihar, Rajasthan, M.P. and Orissa. 
Confidence of parents and patients in private schools and facilities > Government schools and facilities.
But there is no reason to believe that private doctors and teachers are more qualified than government doctors and teachers.
Reasons for such a preference:
Parents and patients feel disrespected by government service providers and may find they get better service if they pay.

  • 6 per cent of the patients see a government doctor or nurse in their private practice rather than in the government dispensary where the same services could be practically free. Government facilities are often irregular in their opening times and teacher and doctor absenteeism adds to the disenchantment.
  • Only about 33 per cent parents of 8-11-year-olds in government schools claim that their children received any praise in the school in the prior month; this proportion is about 55 per cent for private schools.
Janani Suraksha Yojana
  • years following the initiation of the JSY document a striking increase in hospital deliveries.
  • This increase is greatest in large focus States. 
  • Most of this improvement is in government hospitals — from 14 per cent to 40 per cent. 
This success may be due to the efforts made by medical personnel in response to cash incentives they receive, and the fact that hurdles to hospital delivery like transportation have received consideration in programme design. Although the quality of maternity care remains a concern

This suggests that focussing on smarter organisation of public services that aligns with provider incentives, and enhances efficiency, offers potential.

As widely expected, the Reserve Bank of India (RBI), on Tuesday, kept the indicative policy rate (repo) unchanged at 8 per cent while taking measures to provide longer term liquidity in the system.
The RBI Governor said that real GDP (gross domestic product) growth was projected to pick up from a little below 5 per cent in 2013-14 to a range of 5-6 per cent in 2014-15, albeit with downside risks to the central estimate of 5.5 per cent.
However, he said that “there are also risks to our central forecast of 8 per cent CPI inflation by January 2015.” These include a less-than-normal monsoon due to possible El Nino effects; uncertainty on the setting of minimum support prices for agricultural commodities; and the setting of other administered prices, especially of fuel, fertilizer and electricity; the outlook for fiscal policy; geo-political developments; and their impact on international commodity prices. There would also be a downward statistical pull on CPI inflation later this year, due to base effects from high inflation during June-November 2013, he said.

RBI adopts new CPI as key measure of inflation

The Reserve Bank of India (RBI) Governor, Raghuram Rajan, on Tuesday, said that the central bank had adopted the new Consumer Price Index (CPI) (combined) as the key measure of inflation.
Earlier, RBI had given more weightage to Wholesale Price Index (WPI) than CPI as the key measure of inflation for all policy purposes.
Some recommendations of Urjit R. Patel Committee report have been implemented
  • adoption of the new CPI (combined) as the key measure of inflation
  • explicit recognition of the glide path for disinflation, 
  • transition to a bi-monthly monetary policy cycle, 
  • progressive reduction in access to overnight liquidity at the fixed repo rate, and
  • a corresponding increase in access to liquidity through term repos, and
  • introduction of longer-tenor term repos as well as, going forward, term reverse repos.

Following on the recommendations of the high-level advisory committee chaired by Bimal Jalan, and after consulting the Election Commission, the RBI will announce in-principle approval for new bank licences.

Supreme Court to find out how Jats were included in OBC list

The Supreme Court on Tuesday directed the Centre to produce all records of its notification to include Jats in the Other Backward Classes (OBC) list for seven States, in order to find out whether it had applied its mind before taking the decision.

writ petitions filed by the OBC Reservation Raksha Samiti, Ram Singh and two others, who sought a direction to quash the March 4 notification, pointing out that the National Commission for Backward Classes (NCBC) had rejected inclusion of Jats in the OBC list.

according to the Indra Sawney judgment (Mandal case), the recommendations of the commission were binding on the government. If the government wanted to take a different view, it should give special reasons

Terming the SpiceJet offer of rupee one fare across its domestic network as ‘predatory’ and a ‘malpractice’, the Directorate General of Civil Aviation (DGCA), on Tuesday, came down heavily on the no-frill carrier, and asked it to stop such pricing immediately.

Such pricing was ‘not only predatory’, but it amounted to ‘malpractice’ under Rule 135 of the Aircraft Rules relating to air tariff, official sources said. The fact that only one or two seats were being offered on each flight at the rate of one rupee amounted to ‘deceiving the travelling public’, they said, adding that the airline was making such an offer for 91 sectors across the country.
Rule 135 says: “When the DGCA is satisfied that any air transport undertaking has established excessive or predatory tariff...or has indulged in oligopolistic practice, he may, by order, issue directions to such air transport undertaking.”

Directorate General of Civil Aviation (India)

The Directorate General of Civil Aviation (DGCA) is the Indian governmental regulatory body for civil aviation under the Ministry of Civil Aviation. This directorate investigates aviation accidents and incidents. 
The Government of India is planning to replace the organisation with a Civil Aviation Authority (CAA), modelled on the lines of the American Federal Aviation Administration (FAA).[3]

Neutrinos - the Ghost Particles

Lots of news is there about India based Neutrino Observatory. So it becomes an important topic for bot prelims and mains.

First we need to understand certain concepts

Standard Model

Under the Standard Model, which has been pieced together by physicists over the last 70 years, the universe is believed to be made up of matter (four per cent atoms and 27 per cent "dark matter" that we cannot observe or explain) and energy (68 per cent "dark energy").
The model explains the way 17 subatomic particles are bound together to create atoms and then matter by three the four fundamental forces of nature: the strong nuclear force, the weak nuclear force and electromagnetism. It excludes the fourth force: gravity.
The particles fit into two categories: 
1. bosons, which transmit forces, and 
2. fermions, which make up matter.

Fermions consist of 6 quark varieties and 6 lepton varieties. Every lepton has a corresponding neutrino (an energy-carrying particle of very low mass and high velocity) and all these particles also have antimatter versions, which behave in the same way, but annihilate upon contact with matter, converting the mass of both particles into pure energy.
Nearly all matter is formed by two types of quark – the up quark and the charm quark – and one type of lepton: the electron. The remaining four quarks (top, down, strange and bottom quarks) and five leptons (electron neutrino, muon, muon neutrino, tau and tau neutrino) are simply larger versions of those three main particle types.

Bosons come in four categories which mediate the three fundamental forces mentioned above. 
1. The most familiar boson is the photon which mediates electromagnetism, which is responsible for the phenomena of electricity, magnetism and light. 
2. W bosons and Z bosons mediate the weak nuclear force and 
3. gluons mediate the strong nuclear force which binds quarks together into larger particles such as neutrons and protons.
The existence of the Higgs boson is also predicted by the Standard Model and it has been found recently. It is thought to be the particle responsible for the mechanism by which all the other particles acquire mass.
The graviton is another hypothetical boson which could mediate the force of gravity. If it were ever found, the Standard Model could finally be replaced by the elusive Theory of Everything, which would unite all four fundamental forces of nature.

Significance of discovery of Higgs Boson
The particle, a boson, was first found last July and many thought that it might not be the correct boson, but once scientists finished recent testing an affirmative judgment was made. They were on the right track.
This discovery is huge to the scientific community because it gives validity to The Standard Model of Physics, which is authoritative theory for particle physics. The only element or particle that is part of the Standard model and hasn't been discovered is the Higgs boson, until now. 

The confirmation was crucial because the model dictates how the basic pieces of matter act together. If it was proved incorrect, or that the there was no Higgs boson, the way modern scientists look at particle physics would be completely altered, therefore changing many of the current technological assumptions.

Dark Energy, Dark Matter 
In the early 1990's, one thing was fairly certain about the expansion of the Universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the Universe had to slow. The Universe is full of matter and the attractive force of gravity pulls all matter together. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the Universe was actually expanding more slowly than it is today. So the expansion of the Universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it. 

What Is Dark Energy? 
More is unknown than is known. We know how much dark energy there is because we know how it affects the Universe's expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the Universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the Universe. Come to think of it, maybe it shouldn't be called "normal" matter at all, since it is such a small fraction of the Universe. 
One explanation for dark energy is that it is a property of space. Albert Einstein was the first person to realize that empty space is not nothing. Space has amazing properties, many of which are just beginning to be understood. The first property that Einstein discovered is that it is possible for more space to come into existence. Then one version of Einstein's gravity theory, the version that contains a cosmological constant, makes a second prediction: "empty space" can possess its own energy. Because this energy is a property of space itself, it would not be diluted as space expands. As more space comes into existence, more of this energy-of-space would appear. As a result, this form of energy would cause the Universe to expand faster and faster. Unfortunately, no one understands why the cosmological constant should even be there, much less why it would have exactly the right value to cause the observed acceleration of the Universe.  

What Is Dark Matter? 

By fitting a theoretical model of the composition of the Universe to the combined set of cosmological observations, scientists have come up with the composition that we described above, ~68% dark energy, ~27% dark matter, ~5% normal matter. What is dark matter? 
We are much more certain what dark matter is not than we are what it is. 


  • First, it is dark, meaning that it is not in the form of stars and planets that we see. Observations show that there is far too little visible matter in the Universe to make up the 27% required by the observations. 
  • Second, it is not in the form of dark clouds of normal matter, matter made up of particles called baryons. We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them. 
  • Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. 


Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see. High concentrations of matter bend light passing near them from objects further away, but we do not see enough lensing events to suggest that such objects to make up the required 25% dark matter contribution. 

Neutrinos



Neutrinos are one of the fundamental particles which make up the universe. They are also one of the least understood.

Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons. Neutrinos are affected only by a "weak" sub-atomic force of much shorter range than electromagnetism, and are therefore able to pass through great distances in matter without being affected by it. If neutrinos have mass, they also interact gravitationally with other massive particles, but gravity is by far the weakest of the four known forces.

Three types of neutrinos are known; there is strong evidence that no additional neutrinos exist, unless their properties are unexpectedly very different from the known types. Each type or "flavor" of neutrino is related to a charged particle (which gives the corresponding neutrino its name).  Hence, the "electron neutrino" is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the muon and the tau (elementary particles are frequently labelled with Greek letters, to confuse the layman). The table below lists the known types of neutrinos (and their electrically charged partners).

Neutrino

Charged Partner
electron (e)
muon (m)
tau (t)

The results of recent neutrino experiments have opened the door to learning much more about neutrinos and their habits. In 2011, researchers turned on the first set of detectors at the Daya Bay Reactor Neutrino Experiment in southern China, hoping to make a key measurement that would help them understand how one type of neutrino turns into another.
In March 2012, after only seven months of taking data, the Daya Bay scientists announced success: They nailed the measurement of theta one-three, one of three so-called “mixing angles” that describe the oscillation of neutrinos between one flavor and another. Previous experiments had shown that theta one-three had to be small, and scientists had begun to wonder whether this mixing angle might be zero. The Daya Bay result, in combination with other neutrino measurements in Japan, South Korea, France and the United States, showed that the angle is small, but definitely not zero.
When the size of that angle was announced, neutrino physicists from around the world cheered. The result opened up the possibility that neutrinos behave differently than antineutrinos, which in turn might help explain the preponderance of matter over antimatter in the universe.

Now scientists are gearing up for new neutrino studies that could lead to answers to some big questions:
  • If you could put neutrinos on a scale, how much would they weigh?
  • Are neutrinos their own antiparticles?
  • Are there more than three kinds of neutrinos?
  • Do neutrinos get their mass the same way other elementary particles do?
  • Why is there more matter than antimatter in the universe?
How do we know they are there at all?
Wily neutrinos usually avoid contact with matter, but every so often, they crash into an atom to produce a signal that allows us to observe them. Fredrick Reines first detected them in 1956, garnering himself a Nobel prize in 1995.

Most commonly, experiments use large pools of water or oil. When neutrinos interact with electrons or nuclei of those water or oil molecules, they give off a flash of light that sensors can detect.

Some extra Gyaan:

String Theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. In string theory, the different types of observed elementary particles arise from the different quantum states of these strings. In addition to the types of particles postulated by the standard model of particle physics, string theory naturally incorporates gravity, and is therefore a candidate for a theory of everything, a self-contained mathematical model that describes all fundamental forces and forms of matter. Aside from this hypothesized role in particle physics, string theory is now widely used as a theoretical tool in physics, and it has shed light on many aspects of quantum field theory and quantum gravity


Quantum field theory
In theoretical physics, quantum field theory (QFT) is a theoretical framework for constructing quantum mechanical models of subatomic particles in particle physics and quasiparticles in condensed matter physics, by treating a particle as an excited state of an underlying physical field. These excited states are called field quanta. For example, quantum electrodynamics (QED) has one electron field and one photon field, quantum chromodynamics (QCD) has one field for each type of quark, and in condensed matter there is an atomic displacement field that gives rise to phonon particles. Ed Witten describes QFT as "by far" the most difficult theory in modern physics

Questions

1. neutrinos are called ghost particles because?

a. they have no mass
b. since they have no charge they are difficult to detect
c. they rarely interact with matter

Q2. Why neutrino detectors are installed deep underground?

a. they are found deep inside the earth
b. so that neutrinos are not confused for cosmic rays
c. the detectors emit harmful radiations

Final reprieve for Bhullar

Devendar Pal Singh Bhullar - convicted of killing nine persons and wounding 17 others in a car bomb attack in Delhi in 1993
Condemned to death thrice in the past, he has now obtained a final reprieve from the Supreme Court.
His death sentence stands commuted to life on two grounds — 
  • that there was an unexplained delay of eight years in disposing of his mercy petition, and 
  • that he suffers from mental illness
both these grounds figure among the supervening circumstances for commutation listed by the Supreme Court in January in Shatrughan Chauhan vs Union of India.  

In the article author says that the Supreme Court overstepped its constitutional power and duty and exercised the sovereign power of clemency, which it never possessed and thus infringed on the separation of powers as stated in the constitution.
The case in question is Shatrughan Chauhan & Anr. vs Union Of India & Ors.
The Supreme Court has the appellate power to reduce a death penalty in regular appeals. However, it has no powers to exercise the remission or commutation while exercising the judicial review of clemency power. But in the case  it commuted a sentence of death to life for 15 persons on the singular ground of delay. 
The errors in the Shatrughan Chauhan decision brought forward the case of three convicts — Murugan, Perarivalan and Santhan — in the Rajiv Gandhi assassination case before the consideration of the Supreme Court. These commutations were ordered on the same grounds as Shatrughan Chauhan & Anr. vs Union Of India & Ors. After commuting the death sentence to life imprisonment for these convicts, the court rendered an unsolicited legal opinion that was neither pleaded nor argued by the petitioners (para 31 of the judgment).
The judgment erroneously declared the power of the State government under the Criminal Procedure Code, to exercise remission of “life sentence” to “no sentence,” and enabled the release of the convicts. 
Tamil Nadu government took political advantage of the “Tamil sentiments” in view of the coming election, exercised the remission power purely for political consideration, and demanded that the Centre act within 72 hours.
Some important gyaan given in the article apart from this:
1. In 1973, a Bench comprising 13 Supreme Court judges ruled by a majority that Article 368 of the Constitution “does not enable Parliament to alter the basic structure or framework of the Constitution.” The Court ruled what has come to be known as “the basic structure” doctrine — a judicial principle that the Indian Constitution has certain “basic features” that cannot be altered or destroyed through amendments by Parliament. Paramount among these are the fundamental rights guarenteed by the Constitution.
2. The principal of the basic structure of the Constitution is enshrined in Article 79 (3) of the Basic Law for the Federal Republic of Germany

Shooting the messenger to kill the message

The article is about the safety of journalists in Pakistan.
Since 1992, 54 journalists have been killed in Pakistan. This year the country shares the number one position with the Democratic Republic of Congo, Afghanistan, Mexico and Ukraine for the maximum number of deaths of journalists.
While the government is planning to set up a media commission and repeatedly talks of the safety of journalists, mere assurances cannot set things right. Mr. Sharif’s commitment to make Pakistan a secure place for the media is a welcome move. In a democracy, a free media must be guaranteed and the right of journalists to report critically has to be respected. They cannot be subjected to intimidation, torture or be murdered for doing their job.

Second sunrise of Indian jihad

The article is about the speculation that has arised from the arrests of key operatives of Indian Mujaheddin (IM).
Speculation - IM is disintegrating and a new army is rising — an army born in Indian towns and cities scarred by communal warfare and hardened in the battlefields of Pakistan’s north-west.
The author has given various cases to prove this speculation.

Communal warfare - Babri Masjid demolition, Gujarat riots of 2002

New jihadist cells have sprung up within India. The recruits include young people, their minds fired by Internet Islamism, as well as veterans once linked to the proscribed Students Islamic Movement of India (SIMI). 
It has long been evident that the gathering storm of violent Islamism in Pakistan would lash India, too. In 2010, al-Qaeda released a posthumous audio message from Egyptian jihadi Said al-Masri, claiming responsibility for the bombing of the German Bakery in Pune. This showed that al-Qaeda had developed links with jihadi groups acting against India did not surprise anyone.

Some extra gyaan from article:

How IM was founded
Founded in April 1977, SIMI, the fountainhead of the modern Indian jihadist movement, was itself driven by the forces of communal violence. From the outset, scholar Yoginder Sikand has said “that Islam alone was the solution to the problems of not just the Muslims of India, but of all Indians and, indeed, of the whole world.” It drew thousands disillusioned with traditional politics, Dr. Sikand has recorded, providing supporters “a sense of power and agency which they were denied in their actual lives.”
From December 1992, following the demolition of the Babri Masjid, SIMI’s language became increasingly aggressive. In a statement in 1996, it declared that since democracy and secularism had failed to protect Muslims, the sole option was to struggle for the caliphate. Soon after, it put up posters calling on Muslims to follow the path of Mahmood Ghaznavi, the 11th century warlord. In 2001, after the 9/11 attacks, SIMI activists organised demonstrations hailing Osama bin-Laden as a “true mujahid.”
Early in the summer of 2004, a group of young men fed up with SIMI’s inability to act on its own talk gathered in the small coastal town of Bhatkal in Mangalore — and founded what we now call the Indian Mujahideen.

President gives away Padma awards

Eminent scientist R A Mashelkar was on Monday conferred the Padma Vibhushan, the second highest civilian award, while acclaimed artiste Kamal Haasan and ace shuttler P Gopichand were among the 12 personalities conferred the Padma Bhushan by President Pranab Mukherjee here.
Award winning actor Vidya Balan, coach of Indian women kabaddi team Sunil Dabas, sand artist Sudarshan Pattnaik and activist Jawahar Lal Kaul were among the 53 personalities conferred the Padma Shri award at a ceremony held at Rashtrapati Bhawan’s Durbar Hall.

Mashelkar (71) is well known globally for his path breaking research in polymer science and engineering.
He has chaired 12 high powered national level committees to look into diverse issues of higher education, national auto fuel policy and measures to deal with the menace of spurious drugs.
Anumolu Ramakrishna, who pioneered the use of precast concrete technology, was conferred the Padma Bhushan posthumously. He passed away last year at the age of 73.

Japan’s whaling not for scientific research, rules ICJ

The UN’s International Court of Justice (ICJ) on Monday asked Japan to stop its whaling programme in the Antarctic.
Japan catches about 1,000 whales each year in the region for what it calls scientific research, BBC reported.
Australia in May 2010 filed a case with the ICJ, arguing that Japan’s programme — under which it kills whales — is actually commercial whaling in disguise.
The court’s decision is considered legally binding, and Japan earlier did say it would abide by the court’s ruling, the report said.

Warming worsens hunger problems: U.N.

Global warming makes feeding the world harder and more expensive, a United Nations scientific panel said.
A warmer world will push food prices higher, trigger “hotspots of hunger” among the world’s poorest people, and put the crunch on Western delights like fine wine and robust coffee, the Intergovernmental Panel on Climate Change (IPCC) concluded in a 32-volume report issued on Monday.
