In the 1990s, neuroscientists identified a class of drugs that showed promise in the area of stroke. NMDA receptor antagonists could limit damage to the brain in animal models of stroke. But one problem complicated testing the drugsShow More Summary
When local news media report about hometown companies, they use fewer negative words than when reporting about nonlocal companies, according to research by business experts at Rice University and the University of Texas at Dallas. read more
Despite ever increasing regulation in drug approval and the rising costs of research, drug research and development remains unexpectedly efficient, a new shows. To investigate the efficiency in the development of new drugs, the researchers analyzed a data set consisting of new drugs approved by the FDA. Show More Summary
People who receive electronic correspondence from work after hours become angry more often than not and that can interfere with their personal lives, a new study from a management researcher shows.
That swim tracks made by tetrapods occur in high numbers in deposits from the Early Triassic is well known. What is less clear is why the tracks are so abundant and well preserved. Paleontologists have now determined that a unique combination...Show More Summary
New technology could help advance blood biomarker capabilities for improved diagnosis, treatment and prognosis of traumatic brain injury (TBI). An estimated 1.7 million Americans suffer a traumatic brain injury each year, and an estimated 5.3 million individuals -- approximately two percent of the U.S. Show More Summary
In theory, a tumor is an army of clones, made up of many copies of the original cancerous cell. But tumor cells don't always act like duplicates, and their unpredictable behavior can create problems for treatment. For while some cells within a tumor succumb to anti-cancer drugs, others may survive to bring the cancer back to life once therapy has ended.
A surgical algorithm developed and implemented by ovarian cancer specialists dramatically increases the frequency of complete removal of all visible tumor – a milestone strongly tied to improved survival. The algorithm is a framework...Show More Summary
Mothers with a high level of prenatal social stressors -- including possibly less control over their own housing situation or economic distress -- had 2.5 times higher odds to have only a partial or no restriction on smoking in their home than those with no stressors, which increases secondhand smoke risk, a study has found.
Researchers have long sought an efficient way to untangle DNA to study its structure -- neatly unraveled and straightened out -- under a microscope. Now, researchers have devised a simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.
Scientists have developed a new test that can predict the survival chances of women with breast cancer by analyzing images of 'hotspots' where there has been a fierce immune reaction to a tumor. Researchers used statistical softwareShow More Summary
Once HIV-1 has hijacked a host cell to make copies of its own RNA genome and viral proteins, it must assemble these components into new virus particles. The orchestration of this intricate assembly process falls to a viral protein known as Gag. Show More Summary
A neural circuit that connects motor planning to movement has been identified by researchers. The study, the researchers say, explains why injuries that disrupt the brain's ability to carry out movement planning typically impair a person's ability to make movements on just one side of his or her body.
It is possible to predict the development of type 1 diabetes, new research indicates. By measuring the presence of autoantibodies in the blood, it is possible to detect whether the immune system has begun to break down the body’s own insulin cells.
Stuffing lithium into a material causes it to expand; can we control it?
The meaning of Spock
After the Willie Soon imbroglio there came news that Dr. Roger Pielke Jr., who is not a climate skeptic, is also under investigation (in what can only be seen as part of a broader witch-hunt). Pielke Jr. writes on his blog, “the Climate Fix” about undisclosed Conflicts Of Interest (COI): I have Tweeted that…
University of Toronto study finds atmosphere will adapt to hotter, wetter climate (photo by Liam Kearney via Flickr) A study led by atmospheric physicists at the University of Toronto finds that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will become stronger…
Guest essay by William M. Briggs, statistician. Reposted from his blog wmbriggs.com A very odd thing happened in Science. Turns out a famous weatherman has been forecasting highs in the 60s then 70s for New York City all winter long. But the temperature never rose above the single digits, teens, twenties, and thirties. One day…
