About 30 years ago, astronomers realised that the Sun resonates like a giant musical instrument with well-defined periods (frequencies). It forms a sort of large, spherical organ pipe. The energy that excites these sound waves comes from the turbulent region just below the Sun`s visible surface.

Observations of the solar sound waves (known as “helioseismology”) have resulted in enormous progress in the exploration of the interior of the Sun, otherwise hidden from view. As is the case on Eart

Nowadays society is deeply concerned with the safety issues, the flight safety in particular. Despite the technological progress, people can not do without dogs` assistance, as no device is capable of replacing the dogs` scent in search of explosive substances and drugs. Dogs are indispensable for differentiating between different individuals by specific smells. To work efficiently a dog needs excellent scent and ability to learn quickly. It is only in Russia that the unique animals -dog and jackal h

Who has not wound up nowhere in an Internet search for information that should be available about a company, an institution, or an organization? Who has not then longed to have someone to talk to who could answer questions with no hassle or waste of time? Johan Åberg, from the Department of Computer Science at Linköping University, Sweden, has studied what such a human help system might look like.

Automatic help systems with computerized answers already exist. But they seldom work very well

A University of Ulster researcher has discovered a new population of cave dwelling crocodiles, never before seen outside their Saharan habitat.

PhD student Tara Shine discovered the cave dwelling crocodiles while living in the remote African country of Mauritania as part of a two and a half year volunteer project.

Previously unknown, except by local tribespeople, the crocodiles live in burrows and caves throughout the dry season and periods of drought – a phenomenon never

Dark-matter detector could pin down the Universe’s missing mass.

Researchers in London are building a cheap dark-matter detector that should be able to spot the exotic particles called WIMPs that are suspected of hiding most of the Universe’s missing mass 1 .

A prototype of the detector has just shown, for the first time, that it can spot something as close to a WIMP as it’s possible to produce in the lab.

WIMP stands for ’weakly interacting massiv

Ex-Soviet Union viruses could fill antibiotic gap.

Russian remedies could take out hardy US bacteria. Long-abandoned by Western medicine, viruses that naturally kill microbes are being imported as a potential substitute for antibiotics.

The emergence of multi-drug-resistant bacteria is intensifying the search for antibiotic replacements. Bemoaning the problem, clinician Glenn Morris of the University of Maryland in College Park got an idea from a colleague from the former Sov
