A new species has been discovered that is helping scientists understand epigenetics: all individuals of the marbled crayfish examined so far have been female. They reproduce by parthenogenesis, the unfertilized ovum develops directly into a new individual, and possess completely identical genetic…

Researchers have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or…

While sedentary behavior (such as watching TV and commuting time) has been linked to negative health effects, it is unclear whether more time spent standing has protective health benefits. New research shows that standing for at least one-quarter of the day has been linked to lower odds of obesity.

Stem cells have two important capabilities: they can develop into a wide range of cell types and simultaneously renew themselves, creating fresh stem cells. Using a model of the blood forming (hematopoietic) system, researchers have now been able to precisely determine, which signaling pathways…

Rates of military sexual trauma among men who served in the military may be as much as 15 times higher than has been previously reported, largely because of barriers associated with stigma, beliefs in myths about male rape, and feelings of helplessness, according to a collection of new articles.

Researchers have found a link between the origin of hepatitis A virus (HAV) and small mammals. With the emergence of Ebola virus from bats and hantaviruses from rodents, investigators say identifying the other species infected with HAV provides novel insight into the evolution of HAV and how it…

People who live alone are more likely to have unhealthy diets lacking key foods, research has found. The study reported inadequate cooking skills, no partner to go shopping with, the increasing cost of food and a lack of motivation to cook were among the reasons people living alone had different…

Patients with unexplained low blood counts and abnormally mutated cells who do not fit the diagnostic criteria for recognized blood cancers should be described as having clonal cytopenias of undetermined significance (CCUS), suggest researchers in a recent paper. The researchers found the condition…

How does a cytostatic like cisplatin or carboplatin actually get into the cell? Scientists have now succeeded in showing that the volume-regulated anion channel VRAC is 50 % responsible for active substance uptake. If one of the VRAC subunits LRRC8A or LRRC8D is down-regulated, cells take up…

Older people with an age-related loss of muscle mass and strength may be at greater risk of falling and bone fractures, according to new research. A study into sarcopenia -- where muscles lose form and function with age -- found that those with the condition reported higher numbers of falls in the…

Empathetic teachers enhance children's motivation and academic skills, such as reading, writing and arithmetic skills. A positive atmosphere created by the teacher also safeguards and increases children's motivation for learning, according to a Finnish study.

In the future, surgical assistants could be relieved by surgeons, to devote their time instead to their own patients. This is expected to be made possible by a device which has been developed by researchers from the project group for automation in medicine and biotechnology.

People with type-1 diabetes could regain their ability to tell when blood sugar levels are low by regularly doing short bursts of high-intensity exercise, according to a preliminary study. The findings could lead to a non-drug based treatment for a potentially life-threatening condition.

Large U.S.-based chain restaurants that voluntarily list calorie counts on their menus average nearly 140 fewer calories per item than those that do not post the information, new research suggests.

Scientists looked at data from nearly 1,000 cases over 38 years in the Democratic Republic of Congo, which has experienced more Ebola outbreaks than any other country since the virus was discovered in 1976.

One of the most powerful predictors in neuropsychiatry is the epsilon 4 (?4) allele of the apolipoprotein gene (APOE). Individuals who carry this ?4 variant of APOE are at increased risk for developing Alzheimer's disease, early age of Alzheimer's disease onset, and more rapid progression of…

Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers have revealed.

Obese people with metabolic syndrome face an unexpected quandary when it comes to vitamin E -- they need more than normal levels of the vitamin because their weight and other problems are causing increased oxidative stress, but those same problems actually cause their effective use of vitamin E to…

Nanoparticles could aid diagnosis and treatment of diseases including cancer -- if the immune system would leave them alone. A new study shows that inducing crosslinks on nanoparticle surface sugars lets them escape mouse immune system and identifies remaining culprit for human immune recognition…

Researchers have developed a model that could be used to predict a drug's side effects on different patients. The proof of concept study is aimed at determining how different individuals will respond to a drug treatment and could help assess whether a drug is suitable for a particular patient based…

Researchers have developed a groundbreaking method to identify and separate stem cells that reside in the tonsils. While stem cells in many other body tissues have been well studied, little is known about these stem cells.

Scientists in recent years have made great progress in characterizing the bacterial population that normally lives on human skin and contributes to health and disease. Now researchers have used state-of-the-art techniques to survey the skin's virus population, or "virome." The study reveals that…
