Major scientific breakthrough as astronomers discover 'super-Earth' orbiting Sun's nearest star

In a major scientific breakthrough, a ‘super-Earth’ has been discoered orbiting the closest single star to the Sun. Astronomers studied Barnard’s Star, a red dwarf just six light years away — practically in our back garden, galactically speaking — and noticed the presence of a “frozen, dimly lit world” at least 3.2 times heavier than Earth. The planet, known as Barnard’s Star b, is the second nearest to Earth outside […]

Air pollution biggest threat for children, 6 lakh died in 2016 by inhaling polluted air, says WHO report

In 2016, approximately 6 lakh children died due to acute lower respiratory infections caused by polluted air, as per a report by the World Health Organisation. WHO in its report states that on a daily basis, around 93 per cent of the world’s children under […]

How solar lanterns are giving power to the people of India and Africa

Clean-energy lights are transforming lives—and creating entrepreneurs—in Africa and India. Prashant Mandal flips on a candy-bar-size LED light in the hut he shares with his wife and four children. Instantly hues of canary yellow and ocean blue—reflecting off the plastic tarps that serve as the family’s roof and walls—fill the cramped space where they sleep. Mandal, a wiry 42-year-old with a thick black beard and a lazy eye, gestures with […]

Can managing cholesterol reduce Alzheimer’s risk?

Managing cholesterol might help reduce Alzheimer’s risk, says researchers, including one of Indian-origin, who identified a genetic link between the progressive brain disorder and heart disease. Examining DNA from more than 1.5 million people, the study showed that risk factors for heart disease such as elevated triglyceride and cholesterol levels (HDL, LDL, and total cholesterol) were genetically related to Alzheimer’s risk. However, genes that contribute to other cardiovascular risk factors, […]

A Blue Pill Is Stopping HIV, World-First Study Shows

An antiviral pill taken daily by thousands of men across Sydney and other parts of Australia led to a globally unprecedented reduction in new HIV cases, showing that a targeted, preventative approach may accelerate progress on ending the AIDS epidemic. New cases of HIV among gay and bisexual men fell by almost a third to the lowest on record, according to the world’s first study to measure the impact of […]

Daily exercise may cut heart attack risk even in polluted areas: Study

Researchers in Denmark, Germany and Spain evaluated outdoor physical activity levels (sports, cycling, walking and gardening) and nitrogen dioxide (NO2 pollutant generated by traffic) exposure in 51,868 adults, aged 50-65. Over a 17.7-year period, there were 2,936 first heart attacks and 324 recurrent heart attacks. Higher levels of pollution were associated with more heart attacks, however, the risk was lower among those who were physically active, the researchers found. Moderate […]

Did you know that too many choices overwhelm your brain

Do you always find it difficult to decide what to order for lunch? According to researchers, this is due to the phenomenon of choice overload, which occurs as a result of too many choices being available to your brain. A study conducted at California Institute of Technology by Colin Camerer reveals new insights into choice overload, including the parts of the brain responsible for it, and how many options the […]

The Royal Swedish Academy of Sciences has decided to award the #NobelPrize in Physics 2018 for groundbreaking inventions in the field of laser physics with one half to Arthur Ashkin and the other half jointly to Gerard Mourou and Donna […]

Air pollution linked to higher risk of dementia: study

Urban air pollution, mostly from vehicles, is associated with an increased risk of dementia, according to research published Wednesday. The link remained even after heavy drinking, smoking and other well established risk factors for dementia were ruled out, the researchers reported in medical journal BMJ Open. Worldwide, about seven percent of people over 65 suffer from Alzheimer’s or some form of dementia, a percentage that rises to 40 percent above […]
