|  New functions for autoimmune disease 'risk' gene identified  | Researchers have identified infection-fighting and inflammation-suppressing functions for a gene associated with human autoimmune disease. The discovery, centered on a gene known as PTPN22, could set into motion new treatment approaches for autoimmune diseases like lupus, rheumatoid arthritis and type 1 diabetes. | Read More » Drinking alcohol during pregnancy affects learning and memory function in offspring?  | Maternal alcohol consumption during pregnancy has detrimental effects on fetal central nervous system development. Maternal alcohol consumption prior to and during pregnancy significantly affects cognitive functions in offspring, which may be related to changes in cyclin-dependent kinase 5 because it is associated with modulation of synaptic plasticity and impaired learning and memory. | Read More » Black bears return to Missouri indicates healthy forests  | Thanks to a reintroduction program in Arkansas during the 50s and 60s, hundreds of bears amble through the forests of southern Missouri, according to a new study by biologists, who warn that although the bear population is still small, outdoor recreationists and homeowners should take precautions in the Ozark forest to avoid attracting bears. | Read More » Genetic key to conquering cholera  | Researchers have long understood that genetics can play a role in how susceptible people are to contracting cholera, but a team of scientists is now uncovering evidence of genetic changes that might also help protect some people from contracting the deadly disease. | Read More » Internet's backbone can readily be made more sustainable, experts say  | The US Department of Energy has announced that it wants to establish minimum energy efficiency standards for all computers and servers sold in the United States. A new study shows that large server farms can, in fact, cut electricity use and greenhouse gas emissions sharply with off-the-shelf equipment and proven energy management practices. | Read More » Missing piece of pediatric cancer puzzle found  | Most of the time, it takes decades of accumulating genetic errors for a tumor to develop. While this explains the general occurrence of cancer in adults, it leaves a gap in understanding of the cause of pediatric tumors. | Read More » Stem cell discovery furthers research on cell-based therapy and cancer  | Stem-cell researchers have found a key role for a protein called BMI1 that may help scientists direct the development of tissues to replace damaged organs in the human body. | Read More » Calcium linked to increased risk of heart disease and death in patients with kidney disease  | Kidney patients who take calcium supplements to lower their phosphorus levels may be at a 22 percent higher risk of death than those who take other non-calcium based treatments, according to a new study. | Read More » Potential for MERS coronavirus to spread internationally  | The life-threatening MERS coronavirus that has emerged in the Middle East could spread faster and wider during two international mass gatherings involving millions of people in the next few months, according to researchers who describe the most likely pathways of international spread based upon worldwide patterns of air travel. | Read More » Pediatric anesthetic risk: Ketamine may damage children's learning ability and memory  | Recent studies have found that anesthesia drugs have neurotoxicity on the developing neurons, causing learning and memory disorders and behavioral abnormalities. Ketamine is commonly used in pediatric anesthesia. A clinical retrospective study found that children under 3 years old who received a long-time surgery, or -- because of surgery -- require ketamine repeatedly, exhibited learning and memory disorders and behavioral abnormalities when they reached school-age. | Read More » A constitutional right to health care: Many countries have it, but not the U.S.  | More than half of the world's countries have some degree of a guaranteed, specific right to public health and medical care for their citizens written into their national constitutions. The United States is one of 86 countries whose constitutions do not guarantee their citizens any kind of health protection. That's the finding of a new study that examines the level and scope of constitutional protection of specific rights to public health and medical care. | Read More » Evolutionary forensics used on hepatitis C virus outbreak  | The rapid molecular evolution of hepatitis C virus (HCV) has been used to help incriminate the source of an outbreak in two Spanish hospitals in the late nineties. The evolutionary techniques used also helped separate those who were infected by the person in question from those infected elsewhere during the same time period. | Read More » Alternative target for breast cancer drugs  | Scientists have identified higher levels of a receptor protein found on the surface of human breast tumor cells that may serve as a new drug target for the treatment of breast cancer. The results show that elevated levels of the protein Ret, which is short for "Rearranged during transfection", are associated with a lower likelihood of survival for breast cancer patients in the years following surgery to remove tumors and cancerous tissue. | Read More » Cheaper anti-cancer drug as effective as expensive drug in treating most common cause of blindness in older adults  | An anti-cancer drug has been proven to be equally as effective in treating the most common cause of blindness in older adults as a more expensive drug specifically formulated for this purpose. | Read More » Heart failure: new treatment option makes heart 'softer'  | Heart failure with concomitant pulmonary hypertension is a growing health problem with a high mortality rate, above all in older people. Cardiologists have now demonstrated the effectiveness of a substance that sticks to the so-called nitric oxide pathway and makes the heart "softer". This demonstrably ensures a clearly improved quality of life. Heart failure is regarded as a "new" common disease; according to expert estimates, in Austria there are around 250,000 people suffering from this condition. | Read More » Eating eggs is not linked to high cholesterol in adolescents, study suggests  | Although in the late 20th century it was maintained that eating more than two eggs a week could increase cholesterol, in recent years experts have begun to refute this myth. Now, a new study has found that eating more eggs is not associated with higher serum cholesterol in adolescents, regardless of how much physical activity they do. | Read More » Controlling friction by tuning van der Waals forces  | For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces acting between the two surfaces in contact – so-called van der Waals forces. The importance of these intermolecular interactions in generating friction has long been known, but has now been demonstrated experimentally for the first time. | Read More » Joint custody? Overnights away from home affect children's attachments  | In joint custody arrangements, infants who spent overnights away from their mothers had less attachment to their mothers, a new study shows. | Read More » Recommended calorie information on menus does not improve consumer choices  | Researchers recently put menu labels to the test by investigating whether providing diners with recommended calorie intake information along with the menu items caloric content would improve their food choices. The study showed that recommended calorie intake information did not help consumers use menu labeling more effectively. | Read More » Moving more may lower stroke risk  | Here's yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke. | Read More » | |
