The Dell Precision M4500 is the world's most powerful 15.6" mobile workstation with Intel Core i7 Extreme edition processor and NVIDIA Quadro FX 1800M GFX graphics solution.

Two studies published in the British Medical Journal today show that obesity and alcohol act together to increase the risk of liver disease in both men and women.

A study by Norwegian and French researchers hopes to provide new understanding of how blood cells adjust gene expression in response to various clinical, biochemical and pathological conditions. The Norwegian Woman and Cancer (NOWAC) postgenome study, published March 12 in the open-access journal PLoS Genetics, highlights numerous blood gene sets affected by one's physical condition, lifestyle factors and exposure variables.

More high risk cases of human papilloma virus (HPV) could be detected by offering home testing kits to women who do not come forward for cervical screening, according to research published in the British Medical Journal today.

Hubert may not be a tropical storm now that it has made landfall in southeastern Madagascar, but it's still a formidable and large storm system. NASA's Aqua satellite revealed that there are still some very high, strong thunderstorms in Hubert's remnants as it continues to bring rains and gusty winds to southeast and south-central Madagascar.

(PhysOrg.com) -- Perched on a peak high in the Chilean Andes, 2200 meters above sea level, the Cerro Tololo Inter-American Observatory has an enviable view of the night sky. In 2011, the Dark Energy Survey collaboration will install the largest digital camera ever built inside the Cerro Tololo dome to gaze deep into the universe. And sitting nearby, gazing at something a little closer to earth, will be the SLAC-built Radiometric All Sky Infrared Camera, or RASICAM.

Tropical Storm 90Q is the second known tropical cyclone to form in the cooler South Atlantic Ocean, and two NASA satellites confirm it is now moving away from Brazil's coast. The first tropical cyclone ever seen in recorded history in the Southern Atlantic was called "Catarina" in 2004.

Europe's most powerful solar power plant is set to start operations in Italy later this year, the US company building the installation on an area as large as 120 football pitches said on Thursday.

The second crash test of a small lightweight helicopter at NASA's Langley Research Center in Hampton, Va., was a smashing success, literally -- just as engineers had predicted.

A California start-up on Thursday went international with a TigerText iPhone application that lets people kill embarrassing text messages after they have been sent out.

Women in the UK who have ever used the oral contraceptive pill are less likely to die from any cause, including all cancers and heart disease, compared with never users, according to research published in the British Medical Journal today.

A group of Argentine scientists, including health experts from the Wildlife Conservation Society, have announced that yellow fever is the culprit in a 2007-2008 die-off of howler monkeys in northeastern Argentina, a finding that underscores the importance of paying attention to the health of wildlife and how the health of people and wild nature are so closely linked.

Scientists studying the Anopheles gambiae mosquito - the main vector of malaria - have found that when the mosquito takes a blood meal, that act triggers two enzymes to form a network of crisscrossing proteins around the ingested blood. The formation of this protein barrier, the researchers found, is part of the normal digestive process that allows so-called "healthy" or commensal gut bacteria to grow without activating mosquito immune responses. But there is a downside: The barrier also prevents the mosquito's immune defense system from clearing any disease-causing agents that may have slipped into the blood meal, such as the Plasmodium malaria parasite, which in turn can be passed on to humans.

VeriSign Inc. -- whose technology is key to allowing Internet users to access Web sites -- says it plans to pour more than $300 million over the next decade into upgrading its infrastructure.

(PhysOrg.com) -- Researchers at the University of Minnesota have created a molecular image of a system that moves electrons between proteins in cells. The achievement is a breakthrough for biology and could provide insights to minimize energy loss in other systems, from nanoscale devices to moving electricity around the country.

Hypertension is the most prevalent treatable risk factor for stroke. One in two adults are affected by it, and the risk of being hypertensive during a lifetime is about 90%. Despite this, the underlying mechanisms by which raised blood pressure can cause cardiovascular disease are poorly understood. Clinical guidelines for the diagnosis and treatment of hypertension focus heavily on mean systolic blood pressure.

As critical care professionals develop a better understanding of the progression of H1N1, they are becoming better prepared to treat children with severe cases, according to a new study that will be published in the March issue of Pediatric Critical Care Medicine (PCCM).

The promise of stem cells lies in their unique ability to differentiate into a multitude of different types of cells. But in order to determine how to use stem cells for new therapeutics, scientists and engineers need to answer a fundamental question: if a stem cell changes to look like a certain type of cell, how do we know if it will behave like a certain type of cell?

System 97P was looking pretty impressive on NASA satellite imagery early today, March 11, and by 10 a.m. ET, it strengthened into Tropical Storm Tomas.

A new NASA-funded study has concluded that Amazon rain forests were remarkably unaffected in the face of once-in-a-century drought in 2005, neither dying nor thriving, contrary to a previously published report and claims by the Intergovernmental Panel on Climate Change.
