Young children are particularly vulnerable to the toxic effects of lead and even low exposure to it can give rise to emotional and behavioural problems, says a study.


Even low lead exposure harms kids


Elevated activity in the hippocampus - the area of the brain that controls learning and memory - is linked with mild cognitive impairment and early stages of Alzheimer's disease.


Alzheimer's disease linked to brain hyperactivity


In a boost to optogenetics, a technology allowing scientists to control brain activity by shining light on neurons, the first light-sensitive molecule that enables neurons to be silenced non-invasively using a light source outside the skull has been developed.


Now, light-sensitive protein can control brain from outside


Only a single gene decides whether a rare form of cancer called thymoma, derived from the epithelial cells of the thymus, an organ critical to the lymphatic system where T-cells, or so-called "killer cells," mature, will be aggressive or non-aggressive, finds a new study.


Gene behind aggressive lymphatic cancer identified


Although greenhouse gases cause greater warming at the poles, few places on the earth will be immune to global warming and the tropics too will likely experience associated climate impacts, such as increased storm intensity, says a study.


Climate change will impact the tropics too: Study


In a new hope for patients in need of organ transplant, scientists have developed a system that can help preserve the organs longer.


New protocol prolongs preservation of donor livers


It is the sperm quality of the donor and not his age that matters in the success of fertility treatment with sperm donation, a study says.


IVF: Quality of sperm, not donors' age matters


Emperor penguins are in danger of dramatic declines by the end of the century due to climate change, says a study, suggesting the iconic animal "fully deserving of endangered status due to climate change".

Parents may wish to openly monitor cell phones of their kids, and check what types of messages they are receiving as researchers have found that kids who receive sexually suggestive text or photo - sexts - are likely to have had sex.


Sexting linked to risky sexual behaviour among kids


Pushing for immediate economic reforms to bail India out from its "precarious financial condition", former union minister Arun Shourie Sunday urged the states to use Article 254 to push for progressive legislations.

How often have you recommended a product to your friends and acquaintances on Facebook? Most likely, not very often. And what stopped you is a fear of social censorship, claims a new research.


Why most Facebook users don't recommend products online?


Tsunami earthquakes may be caused by extinct undersea volcanoes causing a "sticking point" between tectonic plates when one plate slides under another, says a new research.

In a finding that may prevent thousands of deaths, researchers have identified new micro organisms that may trigger diarrhoeal disease and others that may protect against it.


New microbes linked to severe diarrhoea identified


Posing serious threat to global health, two forms of tuberculosis (TB) have become resistant to rifampicin, regarded the most effective drug against TB, researchers from India and the US say.


Soon, a drug to treat antibiotic-resistant TB


Climatologists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles.


Ocean currents behind change in ice ages?


Researchers have discovered a new form of neurotransmission that influences long-lasting memory created by addictive drugs like cocaine and opioids and the craving for them.


Brain signal that may help in drug de-addiction


Do monkeys, like humans, have hot-hand fallacy? Yes, reveals a new study.


Monkeys believe in 'winning streaks'


In a breakthrough that may help in developing drugs for Alzheimer's and other neurological disorders, researchers have developed a 3D view of an important receptor in the brain.
