Scientist divers to investigate coral reefs for impact of global warming, pollution and population growth in and around Farasan Islands
Khaled bin Sultan Living Oceans Foundation will lead an all-star team of scientist divers on an expedition to study the “rainforests” of the Red Sea. State-of-the-art technology will enable the team to complete years of coral reef research in just three weeks. The research will focus on threats to coral health such as global climate change, ecoto
International collaboration brings up first samples of hard rock called gabbro in intact ocean crust
Scientists aboard the research drilling ship JOIDES Resolution have, for the first time, drilled into a fossil magma chamber under intact ocean crust. There, 1.4 kilometers beneath the sea floor, they have recovered samples of gabbro: a hard, black rock that forms when molten magma is trapped beneath Earth’s surface and cools slowly.
The scientists, affiliated with the Int
Researchers at The University of Texas M. D. Anderson Cancer Center have created a new class of hybrid virus and demonstrated its ability to find, highlight, and deliver genes to tumors in mice.
Researchers say the advance, reported in the journal Cell, is potentially an important step in making human cancer both more visible and accessible to treatment; it may also allow prediction and monitoring of how specific anti-cancer agents are actually working.

Researchers at Fox Chase Cancer Center have developed a new technique to speed discovery of drug targets in chemical genetics. As highlighted on the April cover of Chemistry & Biology, Fox Chase researcher Jeffrey R. Peterson, Ph.D., and his colleagues describe a new way to swiftly find the proteins targeted by small molecule inhibitors during high-throughput screening (HTS) experiments. The new work offers a critical solution to a common stumbling block in this booming field of drug discovery.
The program has been used in DeKalb County and will be installed throughout Georgia. The program is also slated to be used in 35 other states.
Your city has 48 hours to vaccinate every man, woman and child to prevent a dangerous pandemic. Where do you put the clinics, how many health care workers will you need and how do you get 2 million people to a finite number of emergency clinics?

Latest study documents sixth species found in two-year period
Frogs and lots of them are being discovered in the Southeast Asia nation of Lao PDR, according to the Bronx Zoo-based Wildlife Conservation Society, which says that six new frog species have been found by scientists over a two-year period.
Working in conjunction with the WCS Laos Program, scientists describe the latest three species in the recent issue of Copeia, the journal of the American Society of Herpetol
An unprecedented marsh gardening project, spanning two states and utilizing the talents of many agencies, is ready to begin this spring. Headed by Dr. Just Cebrian, Senior Marine Scientist at the Dauphin Island Sea Lab, this ambitious “greening of the estuaries” seeks to establish new, or rehabilitate existing, marsh sites.
In 2002, the Mobile Bay National Estuary Program’s Comprehensive Conservation and Management Plan was approved by the Environmental Protection Agency. Thi
Human-induced climate change could ultimately influence deep Earth processes
The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet.
“In geology, we have this idea that erosion’s going to affect merely the surface,” says Russell Pysklywec, a professor
Driver inattention is the leading factor in most crashes and near-crashes, according to a landmark research report released today by the National Highway Traffic Safety Administration (NHTSA) and the Virginia Tech Transportation Institute (VTTI).
Nearly 80 percent of crashes and 65 percent of near-crashes involved some form of driver inattention within three seconds before the event. Primary causes of driver inattention are distracting activities, such as cell phone use, and drowsiness.
New research shows that a protein made by a cancer virus causes infected immune cells to cling to other immune cells, enabling the virus to spread.
The virus, the human T lymphotropic virus type 1 (HTLV-1), is transmitted mainly when infected cells known as T lymphocytes, or T cells, touch uninfected T cells.
The finding helps explain how this cell-to-cell transmission happens. It suggests that an HTLV-1 protein known as p12 activates infected T cells and causes them to
Playground taunts may seem like harmless child’s play, but bullying may keep overweight children on the sidelines, making it more difficult for them to shed pounds, University of Florida researchers say.
Most kids are bullied at some point in their lives, but overweight children are more often the targets of bullies’ slings and arrows. Now a new UF study reveals this frequently leads them to avoid situations where they have been picked on before, such as gym class and

Duke-led team ran some 1,000 computer simulations, covering 1,000 years, to get a longer-range assessmentDURHAM, N.C. — Instrumental readings made during the past century offer ample evidence that carbon dioxide and other “greenhouse gases” in the atmosphere are warming Earth’s climate, a team led by Duke University scientists has reported. But by analyzing indirect ev
For the last few years, women have heard conflicting reports about the risks and benefits of hormone replacement therapy (HRT). A new study that analyzes many trials together concludes that HRT can reduce heart attacks by about one-third in women under age 60 but has mixed results for older women.
The statistical analysis of 23 trials with more than 39,000 women found that when women started HRT (estrogen with or without progesterone) in their 50s to relieve such menopausal sympt
Try mixing caramel into vanilla ice cream — you will always end up with globs and swirls of caramel. Scientists are finding that galaxies may distribute themselves in similar ways throughout the universe and in places where there is lots of so-called dark matter.
“Our findings suggest that unseen dark matter — which emits no light but has mass — has had a major effect on the formation and evolution of galaxies, and that bright active galaxies are only born within dark matter
Cellulose–a fibrous molecule found in all plants–is the most abundant biological material on Earth. It is also a favored target of renewable, plant-based biofuels research. Despite overwhelming interest, scientists know relatively little about how plant cells synthesize individual cellulose fibers.
However, recent work from the Carnegie Institution’s Department of Plant Biology and Stanford University describes the first real-time observations of cellulose fiber formation. The re
