Researchers identify key step in cocaine-induced heart enlargement, sudden death
Cocaine, in concentrations commonly sold on the street, causes the abnormal buildup of primitive proteins in heart muscle - a process causing heart enlargement that can ultimately lead to sudden death.   view more (2006-09-08)

Stardust comet dust resembles asteroid materials
Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials.   view more (2008-01-25)

Ancient birds flew on all-fours
The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist.   view more (2006-09-22)

Earth's Core is a Recycling Product
The planets of the solar system, including the Earth, formed about four and a half billion years ago from a swirling disk of gas and dust that was left over from the newly formed Sun. However, we do not understand, why the Earth ended up being different from other Earth-like or «terrestrial»... view more (2004-02-04)

Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs.   view more (2007-08-01)

Red dust in planet-forming disk may harbor precursors to life
Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star.   view more (2008-01-04)

Diamonds from outer space — Geologists discover origin of Earth's mysterious black diamonds
If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space.   view more (2007-01-10)

A New Russian Meteorite?
On Thursday 3 October, residents of the village of Bodaibo in the Irkutsk region of Siberia witnessed the fall of a large glowing object from space. Witnesses saw a large fireball in the sky, followed by a thunder-like sound, a flash of light, and a small earth tremor. Scientists from the Institute... view more (2002-10-04)

Moon and Earth Formed out of Identical Material
According to the «Giant Impact» theory the moon was formed by a collision between a proto-earth and a smaller planet. In the October 12 issue of Science, ETH researchers present results showing that the composition of the oxygen isotopes of the moon and the earth are identical. This is a strong... view more (2001-10-11)

Search For Life On Mars?
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE Date: 9 November 1998 For immediate release   view more (1998-11-09)

Ancient mineral shows early Earth climate tough on continents
A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents.   view more (2008-06-16)

University of Pennsylvania Researchers Discover "Killer" B Cells; New Link in the Evolution of Immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the immune systems of fish and mammals in the form of a primitive version of B cells, white blood cells of the immune system.   view more (2006-09-21)

Living fossil still calls Australia home
They are separated by a vast ocean and by millions of years, but tiny prehistoric bones found on an Australian farm have been directly linked to a strange and secretive little animal that lives today in the southern rainforests of South America.   view more (2008-03-26)

Unusual meteorite unlocks treasure trove of solar system secrets
An unusual meteorite that fell on a frozen lake in Canada five years ago has led a Florida State University geochemist to a breakthrough in understanding the origin of the chemical elements that make up our solar system.   view more (2005-09-28)

Methane-Belching Bugs Inspire a New Theory of the Origin of Life on Earth
Two laboratories at Penn State set out to show how an obscure undersea microbe metabolizes carbon monoxide into methane and vinegar.   view more (2006-05-15)

ISO finding questions accepted theory that liquid water was present in young solar system
Planet-like bodies with liquid water formed very early in the history of the Solar System, or so scientists used to think. That scenario may now be due for revision after a finding with ESA`s Infrared Space Observatory, ISO. The theory was based on the presence of certain minerals called carbonates... view more (2002-01-17)

Unexpected discovery about earth's core
The core of the earth doesn't look the way it was expected to. Scientists at the Royal Institute of Technology in Stockholm, Sweden , KTH, can now show that iron, under extremely high pressure, such as that found in the inner earth, takes on unexpected properties, and this can be of importance in... view more (2003-08-29)

Stanford research sheds light on key trigger of embryonic stem cell differentiation
Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine. Harnessing the signals that influence the cells' fate may help... view more (2008-11-06)

'Killer' B cells provide new link in the evolution of immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the most primitive innate form of immune defense, which has survived in fish, to the more advanced, adaptive immune response present in humans and other mammals.   view more (2006-10-04)

Silicon May Have Been The Key To Start Of Life On Earth
A scientist at the University of Sheffield has discovered that silicon may have been key to the establishment of life on earth. Until now it has generally been thought that bacteria do not interact with silicon, but Dr Milton Wainwright and his team at the University's Department of Molecular... view more (2003-10-23)

IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was... view more (2003-08-06)

Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice.   view more (2005-12-06)

Armour-plated fish and the evolution of dentists
The discovery of small spikes lining the mouths of primitive fossil fish reveal surprising new details about how early animals fed. New research published today in a Royal Society paper sheds light on how teeth evolved. Primitive fish did not have jaws or fins but were covered in rigid bony scales... view more (2002-01-07)

Deep Space Brine
Scientists from The University of Manchester have found traces of sea water in a meteorite that fell in Morocco in 1998.   This discovery shows that the necessary conditions for life in the Universe may have existed much earlier than previously believed. The team found salt crystals... view more (2000-06-08)

Supernova radioisotopes show sun was born in star cluster, scientists say
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign.   view more (2006-10-05)
