Hydrocarbons in the Horsehead mane

Observing the edge of the famous Horsehead Nebula with the IRAM interferometer located on the Plateau de Bures (France), a team of French and Spanish astronomers discovered a large quantity of small hydrocarbon molecules. This is a surprise because the intense UV radiation illuminating the Nebula should destroy the small hydrocarbons near the edge. The astronomers suggest that these molecules might result from the fragmentation of giant molecules, called “polycyclic aromatic hydrocarbons” (PAH

The Wind Is Blowing, The Earth Is Rotating

It will be possible to forecast any natural or social cataclysm by attentively observing the speed of the Earth’s rotation and shift of its poles.

The Earth rotates non-uniformly, its poles move, and the rotation axis fluctuates in space. According to the opinion of N.S. Sidorenkov, Doctor of Science (Physics&Mathematics), knowledge of reasons and regularities of our planet’s movement gives the opportunity to forecast with high precision the weather, earthquakes, convulsion of

Sussex scientist makes MRSA treatment breakthrough with synthetic antibiotic

A groundbreaking new treatment to combat the hospital killer bug MRSA, which is estimated to cause up to 5,000 deaths a year in Britain, is being developed by a University of Sussex scientist.

Philip Parsons, a professor of organic chemistry, has devised a simple “one-pot” method to make a synthetic version of a natural antibiotic, lactonamycin, which could be used to treat infected patients. He has now received a £280,000 grant from the Engineering and Physical Sciences Research

Revolutionary grassroots astrophysics project ’Einstein@Home’ goes live

Distributed computing project to search for gravitational waves.

A new grassroots computing project dubbed Einstein@Home, which will let anyone with a personal computer contribute to cutting edge astrophysics research, will be officially announced at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington DC on Saturday, February 19. LIGO Laboratory Director Barry Barish of Caltech and Einstein@Home Principal Investigator Bruce Allen

Muon opportunists: Detecting the unseen with natural probes

Earth is showered constantly by particles called muons that are created by cosmic rays, and clever scientists are finding ways to use them as probes of dense objects, including a massive pyramid in Mexico and volcanoes in Japan. American researchers also have proposed using the energetic particles to detect smuggled nuclear materials in vehicles and cargo containers.

Muons are formed when cosmic rays from deep space interact with the atmosphere. The particles, which strike earth&#1

New satellite observations reveal surprising features of mysterious gamma-ray blasts from Earth

A particle accelerator operates in Earth’s upper atmosphere above major thunderstorms at energies comparable to some of the most exotic environments in the universe, according to new satellite observations of terrestrial gamma-ray flashes.

Terrestrial gamma-ray flashes (TGFs) are very short blasts of gamma rays, lasting about one millisecond, that are emitted into space from Earth’s upper atmosphere. The gamma rays are thought to be emitted by electrons traveling at n
