Super-sticky 'ultra-bad' cholesterol revealed in people at high risk of heart disease (May 27, 2011) -- Scientists have discovered why a newly found form of cholesterol seems to be 'ultra-bad', leading to increased risk of heart disease. The discovery could lead to new treatments to prevent heart disease particularly in people with type 2 diabetes and the elderly. ... > full story

Key molecule for stem cell pluripotency discovered (May 27, 2011) -- Researchers have discovered what enables embryonic stem cells to differentiate into diverse cell types and thus to be pluripotent. This pluripotency depends on a molecule -- E-cadherin -- hitherto primarily known for its role in mediating cell-cell adhesion. If E-cadherin is absent, the stem cells lose their pluripotency. The molecule also plays a crucial role in the reprogramming of body cells into pluripotent stem cells. ... > full story

New procedure to make brain surgery safer (May 27, 2011) -- To increase patient safety in clinical practice and minimize risks and damage that may arise during surgery, computer support and digital medical imaging are key technologies. Before brain operations, neurosurgeons can now evaluate patient-specific surgical risks, achieve increased safety, and avoid unacceptable risks. ... > full story

Does our personality affect our level of attractiveness? (May 27, 2011) -- Part of what determines how much success you will have in the dating world is whether you have a good sense of whether people find you attractive. ... > full story

Scientists turn human skin cells directly into neurons, skipping IPS stage (May 27, 2011) -- Human skin cells can be converted directly into functional neurons in a period of four to five weeks with the addition of just four proteins, according to a new study. The finding is significant because it bypasses the need to first create induced pluripotent stem cells, and may make it much easier to generate patient- or disease-specific neurons for study in a laboratory dish. ... > full story

Study confirms link between rheumatoid arthritis and COPD (May 27, 2011) -- Patients with rheumatoid arthritis are two times more likely to have concurrent chronic obstructive pulmonary disease (COPD) than healthy controls -- an association which was sustained even when variables such as age, gender, smoking and obesity were controlled for, according to a new study. ... > full story

Fish oil may have positive effects on mood, alcohol craving, new study shows (May 27, 2011) -- Omega 3 fatty acids may be beneficial for more than just the heart. Researchers have found at a molecular level a potential therapeutic benefit from these dietary supplements for treating alcohol abuse and psychiatric disorders. ... > full story

Drug may help overwrite bad memories (May 27, 2011) -- Recalling painful memories while under the influence of the drug metyrapone reduces the brain's ability to re-record the negative emotions associated with them. ... > full story

Naturally occurring plant alkaloids could slow down Alzheimer's disease, study suggests (May 27, 2011) -- A family of naturally occurring plant compounds could help prevent or delay memory loss associated with Alzheimer's disease, according to a new study. ... > full story

Genetic basis for key parasite function in malaria (May 27, 2011) -- Snug inside a human red blood cell, the malaria parasite hides from the immune system and fuels its growth by digesting hemoglobin, the cell's main protein. The parasite, however, must obtain additional nutrients from the bloodstream via tiny pores in the cell membrane. Now, investigators have found the genes that malaria parasites use to create these feeding pores. ... > full story

Stress may increase risk for Alzheimer's disease (May 27, 2011) -- Stress promotes neuropathological changes that are also seen in Alzheimer's disease. Scientists in Germany have discovered that the increased release of stress hormones in rats leads to generation of abnormally phosphorylated tau protein in the brain and ultimately, memory loss. ... > full story

Nanoengineers invent new biomaterial that more closely mimics human tissue (May 27, 2011) -- A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The invention from nanoengineers marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue. ... > full story
