The study suggests that tweaking this signaling pathway could potentially mend damaged blood-brain barriers in patients with stroke or other conditions.
UC San Diego computer scientists found that people first fixate on the left of the center of the nose and then the center of the nose to determine if a face is familiar. Looking at two spots, such as the nose and eye, does not improve recognition, but allows for better performance. Understanding how humans recognize faces may help crea...
A recent study has found that anxiety levels in mice are directly influenced by the immune system, specifically through mast cells. Mice without mast cells showed reduced willingness to navigate open and high spaces, indicating lower anxiety levels.
A new study suggests that racial bias affects face perception, with names significantly influencing how people see multiracial faces. Researchers used a study titled Barack Obama or Barry Dunham? to test the hypothesis that racially-suggestive names would influence participants' perception of identical multiracial faces.
A new study challenged conventional notions about salmon survival, finding that juvenile salmon in two west coast rivers had similar survival rates despite the presence of extensive dam networks. The study used tagging and tracking technologies to track small juvenile Pacific salmon from freshwater to ocean destinations.
The global financial crisis may delay the discovery and production of many new life-saving medicines due to reduced investment in biotechnology research. Biotechs made profits for the first time last year, but financing is still a struggle.
Researchers have identified a single microRNA, miR-138, critical to the development of heart chambers in zebrafish. This discovery may provide new approaches for treating congenital heart defects. The study showed that miR-138 regulates numerous gene functions and is required during a specific developmental window.

Researchers found that transcranial direct current stimulation (tDCS) can improve delicate task performance by 24%, outperforming single-hemisphere and sham treatments. The study used healthy volunteers to test the effects of dual-hemisphere tDCS, showing significant benefits for non-dominant hand skills.
Researchers used transcranial magnetic stimulation to restore some experience of color in a patient with 'blindsight', a condition where people don't consciously see but can detect objects. The breakthrough suggests that even damaged parts of the brain, like V1, are not essential for visual awareness.

A study found that diabetes treatment costs increased from $6.7 billion in 2001 to $12.5 billion in 2007, driven by the rise of newer, more expensive medications. The average number of medications per patient also increased, with only 47% prescribed a single drug in 2007.
Off-label prescription of a drug is generally legal, but promotion of off-label uses by drug manufacturers is illegal. Drug companies employ techniques such as the 'decoy indication' and using unlicensed representatives to promote off-label use, potentially putting patients at risk.
A recent study found that 87% of physicians receive less than 5 hours of training on tobacco dependence, and only 6% know Agency for Healthcare Research and Quality guidelines. This lack of knowledge may contribute to low quit rates among smokers, who are more likely to succeed with provider assistance.
A new study by Stanford researchers found that newer, more expensive diabetes medications do not automatically translate to improved patient outcomes. The study suggests that the higher cost of these medications may be due in part to increased use and diagnosis rates, rather than actual clinical benefits.
Researchers successfully tracked juvenile Pacific salmon from their release in freshwater to distant ocean destinations, providing insights into their life experience and decline. The study also found that survival rates were comparable between dammed and un-dammed rivers.
Researchers found that stress activates immune cells, which initiate and perpetuate skin diseases. Blocking specific proteins prevented the increase in white blood cells, suggesting a key role for ICAM-1/LFA-1 interactions.
Scientists at Harvard University found that different plant families near Walden Pond have reacted to climate change in varying ways, with some facing sharp declines or local extinction due to their inability to adjust flowering times, while others remain more resilient.
Researchers at the University of Michigan found that declines in anti-Mullerian hormone (AMH) and inhibin B concentrations predict the time to menopause, while changes in follicle-stimulating hormone (FSH) stages identify different reproductive periods. This information can help women understand their biological clock and fertility.

Research suggests that cerebral inflammation and microglia activation contribute to schizophrenia development. Anti-inflammatory agents targeting activated microglia may provide a new treatment option for the condition.
A new study reveals that acidification of oceans from human CO2 emissions can worsen coral bleaching and death. Key findings indicate that coralline algae may be lost in near future due to increased CO2 levels. On the positive side, some coral species show ability to cope with ocean acidification by enhancing photosynthesis.

Research published in BMC Pediatrics reveals that children who engage in behaviors like sexual activity, alcohol consumption, and smoking are more likely to use methamphetamines. Long-term use of the drug can be a serious problem due to its low cost and ready availability.
A study of 2,432 older Canadians found that positive outlook, low stress, and no smoking contribute to healthy aging. Factors such as moderate income, absence of chronic illness, and moderate alcohol consumption also play a role.
Research suggests that birth hypoxia may contribute to the development of schizophrenia by reducing brain-derived neurotrophic factor (BDNF) levels. The study found a significant decrease in BDNF among individuals who later developed schizophrenia, highlighting the importance of maternal health during pregnancy.
A woman with phonagnosia, unable to recognize her daughter's voice on the phone, undergoes tests that reveal difficulties in recognizing famous actors' voices but not other sounds or music. The study suggests there may be more people with similar conditions, and researchers seek contact from potential sufferers.
A new study found that salmon smolts survive at similar rates of 70-80% in both the Columbia and Fraser rivers, with differences attributed to stressors such as dams, water temperature, and contaminants. The research used acoustic and transponder tags to track survival rates over a four-year period.
Researchers found that ants living more than 60 miles inland preferred a 1% salt solution over a sugar solution 10 times more concentrated. This preference was true for plant-eating ants, but not carnivorous ones.
Researchers at Georgetown University Medical Center have successfully tested a genetic strategy to treat human infections caused by Candida albicans. Inhibiting a key protein could provide a new drug target against the yeast, which inhabits mucous membranes of most humans.
Researchers have invented a device called chemistrode that can stimulate, record and analyze molecular signals at high resolution. The device can be used on any surface and has the potential to study diseases such as diabetes and neurology disorders.
A study by the Wildlife Conservation Society found that roads in Central Africa's Congo Basin are creating 'siege mentality' among forest elephants, forcing them to become isolated and confined. This reduces their ability to find suitable habitat and increases the risk of poaching.
The University of Missouri Health Communication Research Center has received an $8.6 million grant to improve health literacy and outcomes for at-risk populations. The grant will fund the continuation of Ozioma, a bi-weekly news service that produces localized cancer-related news releases for black communities.
A study published in PLoS Medicine calls for strengthened restrictions on off-label promotion by pharmaceutical companies, citing potential dangers to public health. The researchers argue that marketing of off-label uses is widespread and should be heavily fined to prioritize patient safety.
