The popular stimulant blocks adenosine receptors, and is the most likely mechanism of central nervous actions that delay exercise-related fatigue, a new study finds

Consuming caffeine, whether in coffee of soft drinks, has been shown to delay fatigue during prolonged exercise. Studies have shown, for example, that ingesting three to nine mg/kg of caffeine can increase the amount of exercise time to achieve by as much as 50 percent. How caffeine achieves this effect has not been ful

Our planet is bombarded every second with a large number of chargeless, seemingly massless, particles that originate in nuclear fusion reactions that power the sun. They’re called neutrinos.

According to The Standard Solar Model – the most substantiated model of the sun – the sun should emit around three times more neutrinos than are actually measured on Earth. They are a source of great interest for scientists who seek to better understand elementary particles and the physics of the s

Proteins, it appears, have taken Frank Sinatra’s “I Did It My Way” close to heart. A new study published in the current issue of Proceedings of the National Academy of Sciences (PNAS) reveals how single proteins, each a few nanometers (billionths of a meter) long, fold to assume their final shape. It shows that even proteins having the same final shape achieve it by taking different routes.

Proteins are the fundamental components of all living cells. They start out as randomly shaped c

In at least one type of endeavor, humans can’t even begin to compete with their best friends. Dogs can be trained to sniff out drugs and explosives or to track down a crime suspect by smell. Why can’t we do the same? Scientists from the Weizmann Institute of Science and the Max Planck Institute for Evolutionary Anthropology propose an explanation for this ancient quandary.

All mammals, including humans, have about 1,000 genes encoding smell-detecting proteins, or olfactory recepto

A team of scientists from Cambridge University and Bristol University, led by Dr Naomi Langmore of the Australian National University, has found that some Australian birds are one step ahead of their British counterparts in their ability to avoid being victimized by cuckoos.

Cuckoos exploit other bird species by laying their eggs in the nests of other birds. Soon after hatching, the cuckoo chick kills host young by tipping them out of the nest. The foster parents then work hard to rear the i

OxLoc Ltd today announced the launch of the Asset Alert for monitoring condition and location of goods in transit and advising the customer of any problems by a text or e-mail alert. The autonomous tag is self powered with its own battery and can be located easily on an asset or container without expensive installation.

Asset Alert is aimed at Intermodel transportation, containers and wagons and uses a number of external sensors to detect conditions such as temperature, relative humidity an
