As shifts change in a hospital, outgoing physicians must "hand off" important information to their replacements in a brief meeting. But a new study of this hand-off process finds that the most important information is not fully conveyed in a majority of cases, even as physicians rate their communication as successful.

Total knee replacement (TKR) successfully relieves pain and improves function in patients with advanced knee arthritis, according to a new study.

A research team has shown how PEGylated polylysine dendrimers, a new type of nano-sized drug delivery system, can be altered to target either the lymphatic system or the bloodstream, which may improve the treatment of particular types of diseases.

Scandinavian scientists have discovered that a species of tree defends itself from herbivore attack by using chemicals emitted by neighboring plants. The study reveals how species of Birch tree absorb chemical compounds from neighboring Marsh tea plants, Rhondodendron tomentosum, in a unique "defense by neighbor strategy."

To grow larger, solid tumors require a network of blood vessels to nourish them. Chemotherapy exploits these vessels to deliver toxic drugs, but is inefficient if the drugs cannot pass quickly enough from the bloodstream into the tumor. A new study describes a way of transiently making the tumor blood vessels leakier, allowing more efficient drug uptake. This work may ultimately enhance delivery of chemotherapies into tumor tissue.

Since 2004, University at Buffalo anthropologist Ezra Zubrow has worked intensively with teams of scientists in the Arctic regions of St. James Bay, Quebec, northern Finland and Kamchatka to understand how humans living 4,000 to 6,000 years ago reacted to climate changes.

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 postgenome study highlights numerous blood gene sets affected by one's physical condition, lifestyle factors and exposure variables.

Sony and Microsoft will both release motion-sensing controllers this year, for the PlayStation 3 and Xbox 360 respectively. Let’s face it: by bringing motion-sensing games to their consoles, S & M are copying Nintendo’s Wii, or at least being heavily influenced by it, if you were feeling kind. Thing is, they don’t seem too fazed about outright nabbing Nintendo’s idea. Actually, they’re pretty shameless, and now Nintendo bossman Reggie Fils-AIme has stepped in to say they should both be...

The usual excuse of "lack of time" for not doing enough exercise is blown away by new research. The study adds to the growing evidence for the benefits of short term high-intensity interval training (HIT) as a time-efficient but safe alternative to traditional types of moderate long term exercise. Astonishingly, it is possible to get more by doing less!

An international team of conservationists says relaxing a current moratorium on ivory sales to allow one-time sales by Zambia and Tanzania could lead to increased slaughter of elephants for their ivory throughout Africa.

Aided by ultrasound guidance, treating tumors with extreme heat or moderate heat may provide a possible therapeutic option, according to early research.

Sudden Cardiac Arrest syndrome (SCA) is poorly understood, but it's a real danger for the otherwise young and healthy. For no apparent reason, the heart suddenly stops beating, and without treatment death may follow within minutes. It's why some athletes drop dead on the track and why a young man, without any warning, suddenly dies while sitting at his desk. SCA accounts for approximately 300,000 deaths per year in the U.S.

The second-ever known tropical cyclone in the South Atlantic Ocean can't escape satellite eyes, and today, the Geostationary Operational Environmental Satellite, GOES-12 captured a visible image of Tropical Storm 90Q now located off the coast of Argentina.

Using green algae to produce hydrocarbon oil for biofuel production is nothing new; nature has been doing so for hundreds of millions of years, according a Texas AgriLife Research scientist.

In a lecture he delivered in 1906, the German physician Paul Ehrlich coined the term Zuberkugel, or "magic bullet," as shorthand for a highly targeted medical treatment. Magic bullets, also called...

One of the oldest available anti-seizure medications, ethosuximide, is the most effective treatment for childhood absence epilepsy, according to initial outcomes published in this week's New England Journal of Medicine.

Einstein's General Theory of Relativity explains gravity in terms of the curvature of space by mass. Dating from the second decade of the 20th century, after more than 90 years it is still the basis of our understanding of how gravity works to shape the cosmos.

It's been quiet about the Google-China dispute for a while now, but today, the silence was broken by China's minister of Industry and Information Technology, Li Yizhong, who stated that Google must either obey Chinese law or "pay the consequences", leaving no room for a compromise. With more and more western countries building their own internet filters and internet monitoring schemes, it becomes ever harder to make a strong fist against China.

Scientists have hit on a new, versatile method to significantly improve the detection of trace chemicals important in such areas as national security, human health and the environment. The research team was able to detect and identify tiny particles of the explosive trinitrotoluene or TNT -- each weighing less than a billionth of a gram -- on the ridges and canals of a fingerprint.
