 | Do western societies promote narcissism?Universitätsmedizin Berlin report that people who grew up in the former western states of Germany have higher levels of narcissism than those whose socialization took place in the former eastern states. Between 1949 and 1989/90, life in West Germany was characterized by a culture of individualism, with life in East Germany was based on more collectivist principles. Both types of societies had a major impact on citizens' levels of self-esteem and, further, on narcissistic tendencies. According to research published in the journal Plos One, the reunification of Germany ushered in a gradual re-balancing of the distribution of these traits among the younger generation. |
Why do we root for the underdog?We are often taught that it is better to be on the winning side than the losing side of a game, but sometimes that may not be the case.

 | Guilty about that afternoon nap? Don't be. It's good for you.You may be familiar with that feeling of overwhelming sleepiness during the mid-afternoon. It's common, occurs whether you've eaten lunch or not, and is caused by a natural dip in alertness from about 1 to 3pm. So, if you find yourself fighting off sleep in the middle of the day and you're somewhere where you can have a nap, then do it. |

 | Starving cancer cells of sugar—does it work?Previous research have shown that rapidly dividing cancer cells require higher levels of sugar than healthy cells. This dependency on sugar distinguishes cancer cells from normal cells and is often used as a treatment option to kill cancer cells. In reality, the results have not been encouraging. Not all cancer cell types are sensitive to the removal of sugar, and even for the cancers that are sensitive, sugar depletion only slows down the rate of cancer progression. The pathways that sensitise cancer cells to sugar deprivation remains poorly understood. |
 | The simple cholesterol test that says if you need statins—and why doctors in UK aren't using itHeart disease stubbornly remains one of the biggest killers in the UK, where there are 7m people living with the condition. During the past 60 years, the management of cholesterol has become an important weapon in the fight against this – and drugs called statins are often used in treatment. |
 | Opinion: Should flu symptoms be treated with antiviral drugs in primary care?Professor Chris Butler of the University of Oxford's Nuffield Department of Primary Care Health Sciences, and GP in the Cwm Taf University Health Board in Wales, is the lead investigator in the world's largest clinical trial in the community of the controversial flu drug oseltamivir (Tamiflu). He explains the background to the trial and what the team are looking to achieve. |
 | Potential enzyme as therapeutic target for diabetesAbnormalities in glucose uptake by the liver (or hepatic glucose uptake; HGU) causes elevations in blood glucose levels following meals, a state that is known as postprandial hyperglycemia. Such abnormalities are observed in obesity and type 2 diabetes and result in an increased risk of cardiovascular complications. Although the exact mechanism of HGU impairment is unknown, there is evidence that it is mediated by abnormal regulation of the enzyme hepatic glucokinase and the glucokinase regulatory protein (GKRP). |

Nearly one out of five NSAID users exceed daily limitChances are you or someone you know has used nonsteroidal anti-inflammatory drugs (NSAIDs) within the last month. NSAIDs, such as Advil (ibuprofen), Aleve (naproxen) and Celebrex, are among the most commonly used medicines in the U.S. These drugs can have serious side effects, including GI bleeding and sometimes heart attacks, and are often taken without medical oversight because many are available over-the-counter. | |
Drug trial protocol redactions by industry sponsors exposedNew research published by the Journal of the Royal Society of Medicine exposes the extent of redactions in protocols for industry-sponsored randomised drug trials. Trial protocols are needed for a proper assessment of the veracity of drug trial reports. The researchers, from the Nordic Cochrane Centre in Copenhagen, found widespread redactions in the protocols for commercially sponsored trials they received from research ethics committees in Denmark. The study is believed to be the first systematic assessment of which information in trial protocols pharmaceutical companies do not wish to disclose to independent researchers. | |
 | The sugar-attaching enzyme that defines colon cancerResearchers have identified an enzyme that is absent in healthy colon tissue but abundant in colon cancer cells, according to a report in the Jan. 26 issue of the Journal of Biological Chemistry. The enzyme appears to drive the conversion of normal colon tissue into cancer by attaching sugar molecules, or glycans, to certain proteins in the cell. Understanding the role that sugar-modified (glycosylated) proteins play in healthy and cancerous cells is an emerging area of cancer biology that may lead to new therapies. |
Aerobic exercise may mildly delay, slightly improve Alzheimer's symptomsAlzheimer's disease (AD) is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults. There is presently no cure for the condition, though treatment options are available. Today, some 5.3 million Americans live with AD, and it is now the sixth leading cause of death in the United States. The number of older adults who will develop AD is expected to more than triple by 2050. | |
 | Study: Site of first chlamydia exposure makes big differenceExposing the gut to chlamydia protects against subsequent infection in the genital tract and other tissues, researchers from UT Health San Antonio discovered.

 | Getting out of hot water—does mobile DNA help?Extremophiles—hardy organisms living in places that would kill most life on Earth—provide fascinating insights into evolution, metabolism and even possible extraterrestrial life. A new study provides insights into how one type of extremophile, a heat-loving microbe that uses ammonia for energy production, may have been able to make the transition from hot springs to more moderate environments across the globe. The first-ever analysis of DNA of a contemporary heat-loving, ammonia-oxidizing organism, published in open-access journal Frontiers in Microbiology, reveals that evolution of the necessary adaptations may have been helped by highly mobile genetic elements and DNA exchange with a variety of other organisms. |
 | Scientists elucidate the mechanism for inserting protein molecules into the outer compartment of mitochondriaResearchers at the University of Freiburg have succeeded in describing how so-called beta-barrel proteins are inserted into the membranes of mitochondria. The proteins enable mitochondria to import and export molecules. With this discovery, the team led by Prof. Dr. Nils Wiedemann and Prof. Dr. Nikolaus Pfanner, in cooperation with the group of Prof. Dr. Carola Hunte, has clarified a fundamental question of protein biochemistry. The findings are published in the journal Science. |
