Clot-busters, caught on tape Posted: 13 Dec 2013 10:53 AM PST Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many researchers have studied the effectiveness of this technique, not much was understood about why it works. Now a team of researchers has collected the first direct evidence showing how these wiggling microbubbles cause a blood clot's demise.

Newly discovered gene interaction could lead to novel cancer therapies Posted: 13 Dec 2013 06:49 AM PST Scientists have revealed how two genes interact to kill a wide range of cancer cells. The genes known as mda-7/IL-24 and SARI could potentially be harnessed to treat both primary and metastatic forms of brain, breast, colon, lung, ovary, prostate, skin and other cancers.

Scientists improve human self-control through electrical brain stimulation Posted: 13 Dec 2013 06:49 AM PST If you have ever said or done the wrong thing at the wrong time, you should read this. Neuroscientists have successfully demonstrated a technique to enhance a form of self-control through a novel form of brain stimulation.

Chimpanzees are rational, not conformists, researchers find Posted: 13 Dec 2013 06:49 AM PST Chimpanzees are sensitive to social influences but they maintain their own strategy to solve a problem rather than conform to what the majority of group members are doing. However, chimpanzees do change their strategy when they can obtain greater rewards, researchers found.

Study breaks blood-brain barriers to understanding Alzheimer's Posted: 13 Dec 2013 06:48 AM PST A study in mice shows how a breakdown of the brain's blood vessels may amplify or cause problems associated with Alzheimer's disease. The results suggest that blood vessel cells called pericytes may provide novel targets for treatments and diagnoses.

Scientists, practitioners don't see eye to eye on repressed memory Posted: 13 Dec 2013 06:48 AM PST Skepticism about repressed traumatic memories has increased over time, but new research shows that psychology researchers and practitioners still tend to hold different beliefs about whether such memories occur and whether they can be accurately retrieved.

Snail fever expected to decline in Africa due to climate change Posted: 13 Dec 2013 06:48 AM PST The dangerous parasite Schistosoma mansoni that causes snail fever in humans could become significantly less common in the future, a new international study predicts. The results are surprising because they contradict the general assumption that climate change leads to greater geographical spread of diseases. The explanation is that the parasite's host snails stand to lose suitable habitat due to climate change.

Wrist fracture significantly raises risk of hip fracture Posted: 13 Dec 2013 06:48 AM PST A new study showed that patients with Colles' fracture are at higher risk than patients with osteoporosis to have a subsequent hip fracture within one year; Colles' fracture and osteoporosis together further increase the risk of hip fracture.

True story: Not everyone lies frequently Posted: 13 Dec 2013 06:48 AM PST Does everybody lie? We are taught that this is common sense and that most people tell little white lies. But perhaps this isn't true. A recent paper found that many people are honest most of the time, that many are honest about their lying, and that some lie a lot.

Disease, not climate change, fueling frog declines in the Andes Posted: 13 Dec 2013 06:48 AM PST Climate change is widely believed to be behind the rapid decline of frog populations in the Andes mountains, but a new study finds that the real culprit is a deadly fungus that has wiped out amphibian species worldwide. Researchers found that highland frogs, while tolerant of increasing temperatures, live in the optimal temperature range for Batrachochytrium dendrobatidis, also known as Bd.

POPUP: Novel organic solar cells Posted: 13 Dec 2013 06:34 AM PST Future solar cells will be light and mechanically flexible. They will be produced at low costs with the help of printing processes. Scientists aim at developing more efficient materials and new architectures for organic photovoltaic devices. They are working on improving the basic understanding and developing new architectures for semitransparent and non-transparent solar cells and modules.

A stop sign for cancer Posted: 13 Dec 2013 06:33 AM PST A particularly aggressive form of leukemia is the acute lymphoblastic leukemia (ALL). It is especially common among children and very difficult to treat. Researchers have now discovered completely new targets for the treatment of blood cancers. Studying the cancer protein STAT5, the scientists found new opportunities for the development of effective anti-cancer drugs.

New discovery on how skin cells form 'bridges' paves the way for advances in wound healing and tissue engineering Posted: 13 Dec 2013 06:28 AM PST Scientists have discovered that outer skin cells are able to unite to form suspended "bridges" during wound healing. The new findings will pave the way for tissue engineering, such as the design of artificial skin, and better wound treatment.

Evidence of mass extinction associated with climate change 375 million years ago discovered in Central Asia Posted: 13 Dec 2013 06:28 AM PST Scientists have found evidence for catastrophic oceanographic events associated with climate change and a mass extinction 375 million years ago that devastated tropical marine ecosystems.

Simple mathematical formula describes human struggles Posted: 12 Dec 2013 03:59 PM PST The world seems to be getting more complex every day -- some might say too complex. But what if every interaction, every potential conflict we have is really very simple and easy to understand? Mathematicians have found a mathematical formula demonstrating just that: the dynamics of every escalating conflict human beings find themselves in, from children who won't stop crying to international terrorism, can be explained rather easily.
