In a big step for securing critical information systems, such as medical records in clinical settings, Dartmouth College researchers have created a new approach to computer security that authenticates users continuously while they are using a terminal and automatically logs them out when they leave or when someone else steps in to use their terminal.

In a big step for securing critical information systems, such as medical records in clinical settings, Dartmouth College researchers have created a new approach to computer security that authenticates users continuously while they are using a terminal and automatically logs them out when they leave or when someone else steps in to use their terminal. Dartmouth’s Trustworthy Health and Wellness (THaW)/ researchers recently presented their findings at the IEEE Symposium on Security & Privacy. Common authentication methods based on passwords, tokens or fingerprints perform one-time authentication and rely on users to log out from the computer terminal when they leave. Continue reading

Immune system of newborn babies stronger than previously thought

Immune system of newborn babies stronger than previously thought

Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study led by King’s College London. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the study published in the journal Nature Medicine . Our immune system is made up of several different types of immune cells, including neutrophils which play an important role in the frontline defense against infection, and lymphocytes: B cells which produce antibodies, and T cells that target cells infected with viruses and microbes.

Program predicts placement of chemical tags that control gene activity

Program predicts placement of chemical tags that control gene activity

Biochemists working at the University of California, San Diego, have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. They describe their analysis and report results from its application to human embryonic cells in a paper published in Nature Methods online September 21. “All of our cells have the same blueprint, the same DNA, although they serve separate functions,” said John Whitaker, lead author of the report Continue reading

VIP: New way to prevent spread of devastating diseases

VIP: New way to prevent spread of devastating diseases

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren’t working Continue reading

New insights on an ancient plague could improve treatments for infections

New insights on an ancient plague could improve treatments for infections

Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections. In a study published online Sept Continue reading

Lack of facial expression leads to perceptions of unhappiness, new research shows

Lack of facial expression leads to perceptions of unhappiness, new research shows

People with facial paralysis are perceived as being less happy simply because they can’t communicate in the universal language of facial expression, a new study from an Oregon State University psychology professor shows. The findings highlight the important role the face plays in everyday communication and indicates people may hold a prejudice against those with facial paralysis because of their disability, said Kathleen Bogart, an assistant professor of psychology in the College of Liberal Arts at Oregon State University. “People are more wary and more likely to form a negative impression of someone with a disability,” Bogart said Continue reading

Reduced energy density in foods can create healthier food environment, may help to reduce obesity

Reduced energy density in foods can create healthier food environment, may help to reduce obesity

On the heels of new research showing that 16 major food and beverage companies have collectively cut 6.4 trillion calories from U.S. food products, The Obesity Society (TOS) issues an official position statement pointing to the pervasive availability of foods high in calories per unit of weight, or energy density, as a contributing factor for weight gain and obesity. The Society goes further to urge food companies to test and market foods that will help individuals reduce the energy density in their diets and better manage body weight. Continue reading
