Exercise improves cognitive function in people older than 50 years: study

Exercise improves cognitive function in people older than 50 years: study

A review of randomized controlled trials has shown that physical exercise including aerobic exercise or strength training of moderate intensity significantly improves cognitive function in people older than 50 years.

Lead researcher Joseph Northey, a PhD candidate at University of Canberra Research Institute for Sport & Exercise, Australia, said that the review of 39 studies showed that thinking and memory skills were most improved when participants exercised the heart and muscles on a regular basis.

A common virus can trigger life-long allergy to gluten: study

A common virus can trigger life-long allergy to gluten: study

A new study has revealed that a symptom-free common virus in infancy can set the stage for a life-long allergy to gluten, leading to celiac disease, which affects millions of people in the United States.

Celiac disease is an autoimmune disorder which occurs when the body has an inappropriate immune response, like an allergy, to the protein gluten. This gluten is found in barley, wheat and rye.

Babies cry more in Britain, Canada & Italy; less in Germany: study

Babies cry more in Britain, Canada & Italy; less in Germany: study

Babies in Britain, Canada and Italy cry the most, while parents in European countries of Denmark and Germany have to deal with the least amount of weeping and fussing, according to a new study report.

A team of researchers from University of Warwick in the United Kingdom formulated first of their kind universal charts for the normal amount of crying among babies during the first three months after their birth.

NASA’s Juno spacecraft whizzes closely by Jupiter

The National Aeronautics & Space Administration’s (NASA’s) Juno space probe whizzed closely by Jupiter on Monday (March 27th) in its fifth flyby of the gas giant, the American space agency announced.

NASA said in a statement that its Juno spacecraft made its closest approach to Jupiter at 4:52 a.m. EDT or 0852 GMT, hovering just 2,700 miles above the gas giant, while traveling at a sped of around 129,000 mph or 208,000 km per hour.

Scientists hope JWST will help detect alien life on exoplanets

Scientists hope JWST will help detect alien life on exoplanets

Scientists searching for alien life hope that an upcoming megatelescope could reveal whether any of the recently discovered 7 Earth-size planets of the TRAPPIST-1 star system have life-supporting atmospheres.

Scheduled to be launched in 2018, the James Webb Space Telescope (JWST) will be sensitive enough to detect or identify the chemical components of the exoplanets' atmospheres as these planets will be passing in front of their host star.

Researchers store human-generated data in DNA

Researchers store human-generated data in DNA

As existing storage technologies are having a hard time keeping up with ever increasing data, scientists are trying to find a solution in biology rather than computers.

DNA molecules use biological codes to store genetic information, but a team of scientists in New York has unveiled a new technique that can allow humans to use DNA for storing human-generated data.

Nearly 4bn-year-old fossils might be earliest evidence of life on Earth

Nearly 4bn-year-old fossils might be earliest evidence of life on Earth

Straw-shaped microfossils discovered in ancient rocks in Canada could be evidence of some of the earliest life on Earth, a team of researchers led by biogeochemist Matthew Dodd reported.

Dodd, a biogeochemist at University College London, and colleagues said that the tiny, tubular structures or microfossils came from ancient microbes that existed on our planet nearly four billion years ago.

While the age of the specimens remains a matter of debate, most scientists believe that they are 3.77 billion years old, which make them the oldest ever found specimens.

Researchers identify new species of ancient marine worm

Researchers identify new species of ancient marine worm

A fresh analysis of specimens stored at the Royal Ontario Museum for more than 20 years helped researchers identify a new species of ancient marine worm, according to a new study.

The specimens were collected by Canadian scientist Derek Armstrong from a remote corner of northern Ontario in 1994. These specimens were part of 400-million-year-old rocks, in which a team of researchers from the Royal Ontario Museum, University of Bristol, and Lund University of Sweden discovered jaws from the Polychaeta.

Atmospheric rivers wreak havoc around the globe: research

Atmospheric rivers wreak havoc around the globe: research

Massive “atmospheric rivers” are responsible for nearly 75 per cent of all extreme winds and rainfalls on the world’s coasts, and roughly 50 per cent of the extreme wind gusts recorded in the past two decades, a new research revealed.

The strange phenomenon of atmospheric rivers can be described as narrow corridors of heavily concentrated moisture suspended in Earth’s atmosphere, which contain up to 15 times more water than the amount of water flowing through the gigantic Mississippi River.

Hidden continent Zealandia discovered underwater

Hidden continent Zealandia discovered underwater

A new study claims that Earth has eight continents but the eighth is hidden under water in the Pacific Ocean, with only small bits, including New Zealand and New Caledonia, being above sea level.

According to geologists, the eighth continent, dubbed Zealandia, lies beneath the waves in the Pacific Ocean. Only a few specks of land, including for New Zealand, Campbell Plateau and Lord Howe Rise, are above sea surface.
