from THE HINDU (January 06, 2019)

1. MGNREGA scheme faces fund shortage

The Mahatma Gandhi National Rural Employment Guarantee Act
scheme is facing a severe fund crunch, with 99% of money allocated already
exhausted three months before the end of the financial year, and 11 States and
Union Territories having a negative net balance.

Studies analysing government data show that the scheme faces
difficulties in meeting the demand for work and paying wages on time. These
issues are likely to be exacerbated by the current fund crisis, according to
worried economists, researchers and workers on the ground.

The scheme’s financial statement shows that as on Saturday,
the total availability of funds was ₹59,032 crore. The total expenditure,
including payment due, stands at ₹58,701 crore. That leaves a slim margin of
only ₹331 crore. For 11 States, that margin is non-existent, as their accounts
are already in the red.

2. Pay, tenure? This job invitation doesn’t part with information

The Centre’s new advertisement for the remaining four
vacancies at the Central Information Commission (CIC) still does not contain
details of the tenure and salary of the position.

This is in accordance with the government’s plans to amend
the RTI Act to give itself the power to set the tenure and salaries of Central
and State Information Commissioners, in a move that critics warn will undermine
the autonomy of these institutions.

The advertisement issued on Friday by the Department of
Personnel and Training (DoPT) simply says, “The salary, allowances and other
terms and conditions of service of the Information Commissioner shall be as may
be specified at the time of appointment of the selected candidate.”

The Centre has previously defended such vague language in a
Supreme Court hearing by saying that it planned to amend the RTI Act. Following
push-back from Opposition parties and RTI activists, the government withdrew
its stated plans to introduce the amendment Bill in Parliament during the
monsoon session.

3. Australian Open will be different?

What are the changes?

Tennis loves its traditions. But the feeling, at least in
the recent past, has been that of a sport trying to slowly chip away at its
perceived anachronism. The plethora of changes announced ahead of next week’s
Australian Open, the first Grand Slam tournament of the year, is to be seen in
that context. Two of them stand out — the introduction of a 10-point tiebreak
at 6-6 in the deciding set and ‘Heat Stress Index’ to replace the old Extreme
Heat Policy. Other changes include the use of serve clock — to be set at 25
seconds — to help speed up matches, Hawk-Eye review technology on all 16
courts, increase in the number of spots in the women’s qualifying draw from 96
to 128, and the inevitable upgrade in the prize money pool.

Why were they needed?

The tiebreak rule has followed a similar move by Wimbledon,
albeit at 12-12 in the decider, to prevent long-drawn matches from messing up
the schedule. At Melbourne, where a night session is a huge attraction, a
marathon encounter extending into the wee hours is undesirable. The change in
heat policy is probably the result of the severe criticism the previous set of
rules came under. In the last edition, Novak Djokovic and Gael Monfils were
vociferous after being forced to play at temperatures that almost touched 40
degrees Celsius. The hospitalisation of Simona Halep, immediately after the
women’s singles final which was played with the roof open, appears to have
forced the organisers’ hands. The serve clocks will help enforce the guideline
that players have 25 seconds to initiate play after the previous point ends.
The additional spots in the women’s qualifying draw is to restore parity with
the men, while the use of line-calling technology on all 16 match courts will
ensure equal conditions for every player in the draw.

How will it impact players?

A final set super tiebreak means encounters like the one in
2017, where Ivo Karlovic defeated Horacio Zeballos 22-20 in the fifth set, will
be a thing of the past. So will be Halep’s memorable 4-6, 6-4, 15-13 win over
Lauren Davis and the 6-3, 4-6, 9-7 semifinal triumph over Angelique Kerber,
both last year. While it is sure to help players physically, the move has
generated criticism, with many arguing that the women’s game could have been
spared. If anything, it was the men’s game which needed trimming and there too
it was felt that curtailing the end would deprive fans of drama. In the 2008
Wimbledon men’s singles final between Roger Federer and Rafael Nadal, it is the
9-7 final set scoreline that everyone remembers and not the initial phase of
the match, went the theory. As to how the new heat policy — which takes into
account air temperature, radiant heat, humidity and wind speed — plays out is
yet to be seen. But tournament director Craig Tiley’s confirmation that none of
2018’s contentious decisions to continue play would have been overturned under
the new system has dampened hopes.

4. The lowdown on blood transfusions

What is the process of donation? What next? How did it come
about? What is it?

A young pregnant woman in a government hospital at a rural
centre in south Tamil Nadu’s Madurai district made an explosive revelation
mid-December. Expecting her second child, she heard from doctors, after she was
admitted following a bout of sickness, that she had tested positive for HIV.

Later, as the story unravelled, in full media glare, it
turns out she had acquired the virus after a blood transfusion in a district
hospital following a diagnosis of anaemia. This opened up a Pandora’s box, and
fear and distrust pervaded the community. Besides flagging the issue of the
availability of safe blood in the State, it set in motion a sequence of events,
mostly tragic, introspection, and some corrective action.

The story did not end, or even begin, there. The blood
donor, who had donated as a replacement donor when a pregnant relative required
a transfusion, only discovered his HIV positive status after a test for a job
interview. He rushed back to the hospital, laden with guilt, to inform
authorities. By then, his blood had been transfused to the pregnant woman, and
she had tested positive. His blood donation history retrospectively exposed
chinks in the blood donation and transfusion cycle in at least two instances.
He had already donated blood in 2016, but his blood was discarded after he
tested positive for HIV. However, though the HIV law mandates that the patient
be informed with counselling about his/her status, in this case the donor
remained in the dark. In the second instance, when he donated his blood in
November last year, two years after the first, the lab failed to test and/or
detect his infection, which was clearly not in the ‘window period’ where the
virus may avoid detection. The donor was distraught, and attempted suicide, and
died in hospital later.

A few days later, another pregnant woman claimed she had
been transfused with HIV-infected blood at Kilpauk Medical College and Hospital
in Chennai. While her claim has been contested stoutly, the two incidents have,
nevertheless, rocked the State that once won plaudits for its prevention of
transmission programmes.

There is a chain of approved processes to be followed in
blood donation, aimed at quality control and negating the possibility of
transmitting infections. Every qualified donor is put through a basic clinical
evaluation (blood pressure and pulse). If normal, a sample of the blood donated
is tested for HIV, Hepatitis B and C, sexually transmitted diseases and
malaria. Meanwhile, the donated blood is stored separately in an ‘unscreened
refrigerator.’ If the sample clears these tests, or if the tests turn negative,
the blood will then be moved to the ‘screened refrigerator.’ If it tests
positive for any of the infections, another sample from the same blood bag is
tested again. If positive, the bag is discarded. The HIV Act mandates that the
blood bank inform the positive donor, besides referring to the appropriate
department for further treatment. When a requirement crops up, the blood bank
does a grouping to confirm that the group is the same, does a cross-match with
the recipient and releases it to the ward.

5. Silver atoms of nanoparticles are mobile, IIT Madras team finds

While atoms in silver metal remain in their positions
forever in bulk material, their behaviour changes completely at the nanoscale,
researchers at Indian Institute of Technology (IIT) Madras have discovered.

When nanoparticles made of two silver isotopes (107Ag and
109Ag) having just 25 atoms each were mixed in solution, a team led by Prof. T.
Pradeep of the Chemistry Department found that the atoms from the two particles
rapidly exchanged their positions. New particles composed of nearly 50% mixture
of both isotopes were formed. This is akin to the exchange of hydrogen and deuterium
atoms when normal and heavy water (D2O) are mixed. Even in an alloy of silver
and gold, a rapid exchange of silver atoms was seen.

The rapid exchange of silver atoms in solution might have
implications in real-life situations. “The properties of nanoparticles such as
catalysis, drug delivery, and biological sensing may all be viewed differently
in view of this rapid atom exchange,” Prof. Pradeep says. “In homogeneous
catalysis involving nanoparticles, the site at which chemistry occurs could be
changing continuously,” the authors write.

The silver particles composed of 25 atoms were protected by
ligands to form clusters. Despite the protection offered by the ligand, the
atom exchange between the two clusters happened in millisecond time-scale. The
new cluster, which was formed by mixing of atoms belonging to two isotopes, had
almost 50:50 ratio of the isotopes.

The researchers found that the rate at which the atoms
exchanged could be controlled by changing the temperature. While the exchange
was rapid at room temperature, at –20 degree C, the exchange rate was slower
and took about 30 seconds to attain equilibrium distribution. The relatively
longer time taken to reach equilibrium allowed the researchers to observe the
in-between states of atom exchange. They found that the atom transfer rate is
similar to that in water.

6. Carbon microneedles: Low-cost, painless injections

Tiny needles less than 1 mm in size have been developed by
researchers from Indian Institute of Technology (IIT) Kharagpur. When arranged
on a patch, the tiny hollow microneedles can be used for painless drug
delivery.

Last year, the team had developed microneedles from a widely
used photosensitive polymer (SU-8). Since the needles were not hard enough and
biocompatible, they modified it using a simple process of extreme heating or
pyrolysis. This produced glassy carbon needles which were almost 300 times
stronger than the original ones. Since it was made of carbon it was also
biocompatible.

Heating removed most of the nitrogen and oxygen in the
polymer and the needle were solely made of carbon. The needles showed no
toxicity when tested on mice models, says Prof. Bidhan Pramanick who completed
his post-doctoral research from the institute. He is one of the corresponding
authors of the work published in Nature Microsystems & Nanoengineering.

The needles were arranged in a patch (10 X10) and tested for
drug delivery. The patch was attached to a 5 ml syringe and flow rate studied.
They found the flow corresponds to the inlet pressure suggesting that drug
delivery can be controlled by managing the pressure.

7. Detecting ultralow levels of mercury in water

Mercury levels in water need to be checked carefully as it
is a toxic substance that contaminates the food chain. A team at Jawaharlal
Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, has found an
innovative way to develop a sensor that operates using Surface Enhanced Raman
Spectroscopy and has high sensitivity (60 X 10-18 M which is 0.01 parts per
quadrillion), far better than other methods of detecting mercury in water.

Mercury is a heavy metal that is predominant in the
environment. It mixes with the environment due to both natural (e.g. volcanic
activity) and anthropogenic (e.g. electrical appliances such as mercury lamps)
activity. Studies have shown that industrial effluents can have higher mercury
levels than that allowed by the WHO and Indian guidelines. With allowed levels
of mercury in drinking water and effluents being in the range of 1–10 microgram
per litre, it becomes necessary to develop sensors that can measure mercury
levels in water with high sensitivity and selectivity.

The small molecule — histidine conjugated perylene diimide
(HPH) —when dissolved in water shows green fluorescence under laser light. When
water contaminated with mercury is added to this solution, the fluorescence is
absent, and the molecules form a hydrogel. This method can detect only up to 5
nanomolar (0.1 parts per billion) of mercury in water. However, the sensitivity
drastically improves with a novel technique developed by T. Govindaraju’s group
in collaboration with that of Suresh Bhargava of RMIT, Australia.

8. Scientists unearth Asia’s first fossil Dioscorea yam leaf

Speak of fossils, and dinosaurs first come to mind. A quaint
fossilised leaf is one of the most recent finds throwing light on India’s past.
The leaf fossil is the first of Dioscorea yams from Asia and hints at a
Gondwanan origin to these plants, claim scientists.

When scientists R. C. Mehrotra and Anumeha Shukla from
Lucknow’s Birbal Sahni Institute of Palaeosciences were leading a dig in the
Eocene-era (38-56 million years ago) Gurha lignite mine in Bikaner in western
Rajasthan, they obtained two well-preserved fossils of large leaves. “They are
about 16 cm long,” wrote co-author Dr. Shukla in an email.

Referring to herbarium sheets available at Dehradun’s Forest
Research Institute, the team identified it as a species of Dioscorea, a kind of
yam that grows as a herbaceous vine in the humid tropics of India and other
countries. They also used the morphological features of the leaves — venation
and leaf shape — to rule out other plants that look very similar to it. When
they compared it to the other Dioscorea fossils obtained from Europe, Africa
and America, they found it to be very distinct.

9. Saliva test for malaria

A new saliva-based test can rapidly identify
individuals who harbour infectious reservoirs of the malaria parasite,
according to a new study by researchers in the U.S. and Africa.

The assay, while still at the proof-of-concept stage, could
provide a non-invasive tool to epidemiologists and clinicians to track down and
target this parasite reservoir (which is responsible for most malaria transmission)
in low-resource settings. Malaria is a massive drain on public health across
areas of the world such as sub-Saharan Africa, where it kills approximately
500,000 children each year. Curtailing transmission of the malaria parasite has
proved difficult because some individuals infected with malaria have no
symptoms.. The test-developers examined saliva samples from 12 children with
subclinical malaria and discovered 35 protein markers of the Plasmodium
falciparum parasite, which causes most malaria infections in humans. They
selected one protein marker, named PSSP17, and have designed a point-of-need
diagnostic test based on a fluorescent antibody that detects the protein in
saliva samples in three to 30 minutes (depending on how much of the protein is
in the sample).

10. Gender responses to brain cancer therapy

Chemotherapy for a deadly form of brain cancer called
glioblastoma is more effective in women than in men, a new study in the U.S.
has found. The

research sheds light on the molecular basis of sex
differences in glioblastoma treatment and suggests that tailoring therapies to
sex differences could lead to improved patient outcomes. The scientists used
MRI-based techniques to analyse tumour growth every two months in a group of 63
glioblastoma patients (40 males and 23 females) who received standard-of-care
treatments such as surgery and the chemotherapeutic drug, temozolomide (TMZ).
The imaging revealed that the female patients displayed lower tumour growth
rates in response to TMZ than male patients, indicating the female patients
benefited more from standard-of-care treatment. The findings appear in Science
Translational Medicine.

11. New source for hepatitis vaccine

A relatively abundant human gene family, VH1-69, may be a
good place to source antibodies that may help make a vaccine for the highly
diverse hepatitis C virus (HCV). The number of new HCV infections in the U.S.
increased threefold from 2010 to 2015, largely due to the increase in injection
drug users caused by the opioid crisis. Hepatitis C can be cured by certain
drugs, but these are expensive, thus limiting them to a small number of people.
The broadly-neutralising antibodies (b-Nabs) from the gene family target a
region called the AR3 of the virus. The study, discovered three new antibody-complex
structures — AR3A, AR3B and AR3D — that target AR3. In further studies, the
scientists said the VH1-69 gene family encoding this viral region leads to
HCV-specific bNAbs. The findings appear in Science Advances.

12. What is inhalable m-RNA?

Messenger RNA, which can induce cells to produce therapeutic
proteins, holds great promise for treating a variety of diseases. The biggest
obstacle to this approach so far has been finding safe and efficient ways to
deliver mRNA molecules to the target cells. Researchers in the U.S. have now
designed an inhalable form of mRNA. They say this aerosol could be administered
directly to the lungs to help treat diseases such as cystic fibrosis. The
researchers also showed that lung cells in mice could produce a target protein,
in this case, a bioluminescent protein. If the same success rate can be
achieved with therapeutic proteins, this could be high enough to treat many
lung diseases, they say.
