Seventy years ago, in 1940, a popular science magazine published a short article that set in motion one of the trendiest intellectual fads of the 20th century. At first glance, there seemed little about the article to augur its subsequent celebrity. Neither the title, “Science and Linguistics,” nor the magazine, M.I.T.’s Technology Review, was most people’s idea of glamour. And the author, a chemi
The scientists have studied the exclusion zone for more than a decade Scientists working in Chernobyl have found a way to predict which species there are likely to be most severely damaged by radioactive contamination. The secret to a species' vulnerability, they say, lies in its DNA. This discovery could reveal which species are most likely to decline or even become extinct in response to other t
The Sun's conveyor transports plasma across its surface to the pole, where it sinks before rising at the equator Solar physicists may have discovered why the Sun recently experienced a prolonged period of weak activity. The most recent so-called "solar minimum" occurred in December 2008. Its drawn-out nature extended the total length of the last solar cycle - the repeating cycle of the Sun's activ
This has allowed it to map the almost imperceptible differences in the pull exerted by the mass of the planet from one place to the next - from the great mountain ranges to the deepest ocean trenches. Two months of observations have now been fashioned into what scientists call the geoid. "I think everyone knows what a level is in relation to construction work, and a geoid is nothing but a level th
A capsule thought to contain the first samples grabbed from the surface of an asteroid has returned to Earth. The Japanese Hayabusa container hit the top of the atmosphere just after 1350 GMT, producing a bright fireball over southern Australia. It had a shield to cope with the heat of re-entry and a parachute for the final drop to the ground. A recovery team later reported they had identified the
Most contemporary Jews descended from ancient residents of the Levant Scientists have shed light on Jewish history with an in-depth genetic study. The researchers analysed genetic samples from 14 Jewish communities across the world and compared them with those from 69 non-Jewish populations. Their study, published in Nature, revealed that most Jewish populations were "genetically closer" to each o
A project at Bangor University aims to explore the benefit of being bilingual. Researchers will be recruiting 700 people aged between two and 80 to take part in the £750,000 programme. Prof Virginia Gathercole said the obvious benefits included being able to converse and to participate in two cultures. But she said there was also evidence of non-language benefits, such as the ability to protect th
