Genomic Variation Easier To Identify With UCSD/Brown Software
When cells reproduce, their DNA is copied - and mistakes are made. These mistakes, or mutations, range from changes in a single letter of the DNA sequence to drastic deletions, duplications or rearrangements of genetic code. view more (2006-12-27)
Scripps research scientists find new link between insulin and core body temperature
A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin-a hormone long associated with metabolism and metabolic disorders such as diabetes-and core body temperature. view more (2009-11-20)
Brown Team Creates Uncanny Cell Replicas for Treatment, Research
Call them genuine fakes. Brown University biomedical engineer Diane Hoffman-Kim and her research team have made plastic replicas of real cells through a novel two-part molding process. The copies looked so authentic, Hoffman-Kim couldn't tell if they were real or rubber at first. view more (2006-09-13)
Modern physics is critical to global warming research
Science has come a long way with predicting climate. Increasingly sophisticated models and instruments can zero in on a specific storm formation or make detailed weather forecasts - all useful to our daily lives. But to understand global climate change, scientists need more than just a one-day forecast. They need a deeper understanding of the... view more... (2008-03-12)
Taking The Sting Out Of Ant Stings (pp979, 1001)
Australian authors of a study in this week's issue of THE LANCET highlight how immunisation to desensitise people to the venom of the jack jumper ant shows great promise for preventing severe systemic reactions in people allergic to this venom. The jack jumper ant (Myrmecia pilosula) is responsible for about 90% of severe systemic reactions to... view more... (2003-03-20)
Living longer in Yorkshire
People across Yorkshire are living longer, but a regional north-south divide in health is widening - a reversal of national patterns of affluence and deprivation, according to geography professor Phil Rees and research student Dominic Brown. view more (2002-06-10)
Researchers Learn Why Immune System's Watch Dogs Howl
Toll-like receptors are the guard dogs of the immune system, sniffing out bacteria and viruses then activating the body's immune system for an attack on these invaders. view more (2007-08-03)
Brown Scientist Answers How Peruvian Meteorite Made It to Earth
Brown University professor Peter Schultz's study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth. view more (2008-03-12)
East African cichlid fish offer new understanding of genetic basis of sex determination
Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. view more (2009-10-02)
Brown-Assisted Trial Finds New Colorectal Screening Procedure Is Accurate and Less Invasive
More patients stand to benefit from a comprehensive, less invasive method to accurately detect colorectal cancer and precancerous polyps, a multicenter study involving Brown University and institutions nationwide has found. view more (2008-09-18)
Hubble sees multiple star generations in a globular cluster
Hubble's observations of the massive globular cluster NGC 2808 provide evidence for three generations of stars that formed early in its life. This is a major upset for conventional theories that propose a single period of star birth. view more (2007-05-03)
First Image and Spectrum of a Dark Matter Object
Astronomers have 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 and the European Southern Observatory's Very Large Telescope. The Riddle of Dark Matter The... view more... (2001-12-05)
1 in 5 bariatric surgery candidates not psychologically cleared for surgery
A new study by Rhode Island Hospital and Brown University researchers reported that 18 percent of 500 candidates for bariatric surgery did not receive the initial psychiatric clearance for the surgery. view more (2007-10-15)
Study plunges standard theory of cosmology into crisis
As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. view more (2009-05-06)
Ideas on gas-giant planet formation take shape
Rocky planets such as Earth and Mars are born when small particles smash together to form larger, planet-sized clusters in a planet-forming disk, but researchers are less sure about how gas-giant planets such as Jupiter and Saturn form. view more (2006-03-23)
Coronary calcium distribution tied to heart attack risk
A new calcium scoring method may better predict a person's risk of heart attack, according to a new multicenter study published in the June issue of the journal Radiology. Calcium coverage scoring takes into account not only the amount of calcified plaque build-up in the coronary arteries, but also its distribution. view more (2008-05-27)
Stellar Clusters Forming in the Blue Dwarf Galaxy NGC 5253
Star formation is one of the most basic phenomena in the Universe. Inside stars, primordial material from the Big Bang is processed into heavier elements that we observe today. In the extended atmospheres of certain types of stars, these elements combine into more complex systems like molecules and dust grains, the building blocks for new planets,... view more...

Exploding star within a star - a recurrent nova!
On 12 February 2006, amateur astronomers reported that a faint star in the constellation of Ophiuchus had suddenly become clearly visible in the night sky without the aid of a telescope. view more (2006-04-07)
Supernova remnants dance in the LMC
The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud. view more (2008-01-11)
Rot's unique wood degrading machinery to be harnessed for better biofuels production
An international team led by scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and the U.S. Department of Agriculture Forest Service, Forest Products Laboratory (FPL) have translated the genetic code that explains the complex biochemical machinery making brown-rot fungi uniquely destructive to wood. view more (2009-02-06)
