Caffeine's safety concerns increase with energy drinks gaining popularity

Wed, 06/25/2014 - 14:23

Caffeine's safety concerns increase with energy drinks gaining popularityWashington, June 25 - New questions regarding the safety of caffeine for consumers has been recently raised as the caffeine-containing energy drinks have surged in popularity.

However, according to a June 23rd panel discussion at the 2014 Institute of Food Technologists (IFT) Annual Meeting and Food Expo in New Orleans there is a rich database of health evidence that had confirmed the safety of caffeine for consumers at current levels of exposure.

But the interaction of caffeine with the myriad of other ingredients that are found in many energy drinks is still unknown.

ESA considering harpooning space debrisWashington, June 25 - Faced with the challenge of capturing tumbling satellites to clear key orbits, ESA is considering harpooning them.

Decades of launches have left Earth surrounded by a halo of space junk: more than 17,000 trackable objects larger than a coffee cup, threatening working missions with catastrophic collision. Even a 1 cm nut could slam into a valuable satellite with the force of a hand grenade.

'Mysterious' X-ray signal could be dark matter candidate

Wed, 06/25/2014 - 11:19

'Mysterious' X-ray signal could be dark matter candidateWashington, June 25 - Researchers are mystified by a mysterious X-ray signal which has been found in a detailed study of galaxy clusters using NASA's Chandra X-ray Observatory and ESA's XMM-Newton.

One intriguing possibility is that the X-rays are produced by the decay of sterile neutrinos, a type of particle that has been proposed as a candidate for dark matter.

While holding exciting potential, these results must be confirmed with additional data to rule out other explanations and determine whether it is plausible that dark matter has been observed.

Earlier, a new tell- all book penned by journalist Edward Klein had revealed that there was "jealousy" between Clintons and Obamas. (ANI)


Investigators eye pilots' actions in Asiana crash

Tue, 06/24/2014 - 14:18

Washington - Nearly a year after Asiana Flight 214 crashed while landing in San Francisco, the National Transportation Safety Board is meeting to determine what went wrong, who's to blame and how to prevent future accidents.

Among the issues raised by the crash of the South Korean airliner are some that long have concerned aviation officials, including hesitancy by some pilots to abort a landing when things go awry or to challenge a captain's actions.

Other issues include an over-reliance on automated controls that perform functions like maintaining airspeed, and the growing complexity of automated systems, which can confuse pilots.

First-ever self-powered cardiac pacemaker to make patients' life easier

Tue, 06/24/2014 - 13:47

First-ever self-powered cardiac pacemaker to make patients' life easierWashington, June 24 - Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have developed a self-powered artificial cardiac pacemaker that is operated semi-permanently by a flexible piezoelectric nanogenerator.

The team headed by Professor Keon Jae Lee of the Department of Materials Science and Engineering at KAIST and Professor Boyoung Joung, M. D. of the Division of Cardiology at Severance Hospital of Yonsei University, newly designed flexible piezoelectric nanogenerator directly stimulated a living rat's heart using electrical energy converted from the small body movements of the rat.

Indian researchers shed light on long unanswered question of superconductivity

Indian researchers shed light on long unanswered question of superconductivityWashington, June 24 - Researchers have shed new light on a long-unanswered question related to superconductivity in so-called transition metal binary alloys.

The team revealed that the local magnetic fluctuations, or spin fluctuations, an intrinsic property of Titanium-Vanadium (Ti-V) alloys, influence superconductivity in a way that is more widespread than previously thought.

Titan's building blocks may pre-date Saturn itself

Tue, 06/24/2014 - 12:25

Titan's building blocks may pre-date Saturn itselfWashington, June 24 - Researchers have claimed to have found evidence about the building blocks of Saturn's moon Titan pre-dating the planet itself.

The researchers found that nitrogen in the atmosphere of Saturn's moon Titan originated in

conditions similar to the cold birthplace of the most ancient comets from the Oort cloud.

The finding has ruled out the possibility that Titan's building blocks formed within the warm disk of material thought to have surrounded the infant planet Saturn during its formation.

White dwarf star that looks like diamond identified

Tue, 06/24/2014 - 12:22

White dwarf star that looks like diamond identifiedWashington, June 24 - A team of astronomers, using multiple telescopes, have identified a faint white dwarf star that looks like diamond.

White dwarfs are the extremely dense end states of stars like our Sun: after their nuclear fuel is exhausted, they collapse from the size of a star (about 1,000,000 miles across) to the size of the Earth (7,000 miles across).

This white dwarf, located in the constellation Aquarius, is so cool that its carbon has crystallized - in other words, it's like a diamond, with a mass similar to that of our Sun.

Indian physicists say Ti-V alloy's local magnetic fluctuations affect superconductivity

Tue, 06/24/2014 - 11:32

Washington, June 24 - Indian physicist have said that the local magnetic fluctuations, or spin fluctuations, an intrinsic property of Titanium-Vanadium (Ti-V) alloys, influence superconductivity in a way that is more widespread than previously thought.

According to the study, it is the competition between these local magnetic fluctuations and the interaction between electrons and collective excitations, referred to as phonons, which determine the superconductivity .

Extreme weather conditions linked to air flow changes

Mon, 06/23/2014 - 17:38

Extreme weather conditions linked to air flow changesWashington, June 23 : A new study has revealed that regional weather extremes, like drought, heat waves and cold spells is linked to air flow.

According to the study, variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions.

According to the researchers, the high altitude winds normally blow from west to east around the planet, but do not follow a straight path and the flow meanders to the north and south, in a wave-like path.
