Faintest Methane Brown Dwarf Discovered with the NTT and VLT
Brown Dwarfs are star-like objects which are heavier than planets but not massive enough to trigger the nuclear burning of hydrogen and other elements which powers normal stars. They are, nevertheless, heated during their formation by gravitational contraction but then continuously cool as this energy is radiated away. The so-called Methane Brown... view more... (1999-08-18)
Enzyme's second messenger contributes to cell overgrowth
Scientists at the University of California, San Diego (UCSD) School of Medicine have uncovered a novel pathway by which hormones elevated in inflammation, cancer and cell injury act on cells to stimulate their growth. view more (2007-09-27)
Hubble panoramic view of Orion Nebula reveals thousands of stars
In one of the most detailed astronomical images ever produced, the NASA/ESA Hubble Space Telescope is offering an unprecedented look at the Orion Nebula. view more (2006-01-12)
German high-school students involved in an astronomical research project
This week, Astronomy & Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students. view more (2009-11-06)
The lower atmosphere of Pluto revealed
Using ESO's Very Large Telescope, astronomers have gained valuable new insights about the atmosphere of the dwarf planet Pluto. The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180... view more...

Astronomers find first habitable Earth-like planet
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. view more (2007-04-25)
Hubble finds infant stars in neighbouring galaxy
Hubble astronomers have uncovered, for the first time, a population of infant stars in the Milky Way satellite galaxy, the Small Magellanic Cloud (SMC, visible to the naked eye in the southern constellation Tucana), located 210,000 light-years away. view more (2005-01-12)
Brown Scientists Explain Inception of Perception in the Brain
The taste of champagne, the sound of a train, the flash of a pop fly into left field - indeed all of human perception - begins in the brain's center. That's where sensory information passes from the thalamus to the neocortex for processing. view more (2007-03-06)
Newer antidepressants led to less, not more, teen suicides
A new study by researchers at the University of South Florida and University of Illinois suggests FDA mandated warnings about suicide in teens treated with antidepressants could have the unintended consequence of placing more youth at risk. view more (2007-09-07)
Brown Study Finds Link Between Depression and Household Mold
A groundbreaking public health study has found a connection between damp, moldy homes and depression. view more (2007-08-30)
Astronomers weigh 'recycled' millisecond pulsar
A team of U.S. and Australian astronomers is announcing today that they have, for the first time, precisely measured the mass of a millisecond pulsar - a tiny, dead star spinning hundreds of times every second. view more (2006-01-13)
New source for biofuels discovered
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up. view more (2008-04-24)
Good Parenting Protects Against Chronic Illness says Professor of Public Health
Research reveals that good parenting not only helps to reduce criminality, conduct disorder and delinquency in children but could promote good health and prevent chronic disease in adulthood, says University of Warwick Professor of Public Health Sarah Stewart-Brown. view more (2004-11-09)
Chromium 6: A Killer Compound With An Improbable Trigger
Even miniscule amounts of chromium 6 can cause cancer. Blame that do-gooder nutrient, vitamin C. view more (2007-03-13)
Brown Researchers Create Novel Technique to Sequence Human Genome
Since the human genome was sequenced six years ago, the cost of producing a high-quality genome sequence has dropped precipitously. view more (2009-04-16)
Compounds could be new class of cancer drugs
A team of Vanderbilt University Medical Center investigators has developed a group of chemical compounds that could represent a new class of drugs for treating cancer. view more (2009-02-04)

Tropical forest seed banks: a blast from the past
Seeds of some tree species in the Panamanian tropical forest can survive for more than 30 years before germinating. view more (2009-04-02)
How Do Bacteria Swim? Brown Physicists Explain
Imagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim. view more (2008-11-20)
First Image and Spectrum of a Dark Matter Object
HST and VLT Identify MACHO as a Small and Cool Star An international team of astronomers has observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope (HST) and the... view more...
