Stress response is associated with manifestations of various psychosomatic and psychiatric disorders. Hence, it is important to understand the underlying mechanisms that influence this association. Moreover, men and women tend to react differently with stress–both psychologically and biologically. These differences also need to be studied in order to have a better understanding in the gender difference observed for many disorders, which are likely to be contributed by the gender difference in...

Scientists at UCL have developed a way to use MRI scans to help identify when HIV is persisting in the brain despite effective drug treatment. The study, published in Clinical Infectious Diseases and funded by Wellcome, shows that patients can have HIV in the brain even when the disease is kept under control by treatment. "Before we had effective treatments for HIV, AIDS often led to dementia and other problems in the brain," explains senior author Professor Ravi Gupta (UCL Infection & I...

A study led by a Massachusetts General Hospital pediatrician finds that children ages 3 to 7 who don’t get enough sleep are more likely to have problems with attention, emotional control and peer relationships in mid-childhood.  Reported online in the journal Academic Pediatrics, the study found significant differences in the responses of parents and teachers to surveys regarding executive function – which includes attention, working memory, reasoning and problem solving – and behavioral problem...

New study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis. Acoustic–gravity waves In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media when the force of gravity or buoyancy tries to restore equilibrium. An example of such an interface is that between the atmosphere and the ocean, which gives rise to wind waves. A theory of guided propagation of sound in layered, movinMITg fluids is extended to ...

Two different studies from the Environmental Working Group examined newborn’s blood, and found over 200+ toxins in newborn’s blood! Some of these toxins were pesticides, Bisphenol A, mercury, some are known to cause cancer, and some are known to be neurotoxic. The babies were exposed in utero to these chemicals directly from the mother’s exposure. Some of these toxins can have an immediate affect, such as low birth weight. But some cause problems later in the child's life. There is a phenomenon ...

A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage. Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria H...

Personalized medicine is a medical procedure that separates patients into different groups—with medical decisions, practices, interventions and/or products being tailored to the individual patient based on their predicted response or risk of disease. The terms personalized medicine, precision medicine, stratified medicine and P4 medicine are used interchangeably to describe this concept though some authors and organisations use these expressions separately to indicate particular nuances. Pers...

SkinCare is a human physiology experiment, which aims at characterizing different parameters of human skin (i.e. hydration grade, transepidermal water loss, skin surface video imaging) in weightlessness and inside the International Space Station. Long-duration missions in microgravity affect skin by causing excessive dryness, increased cell loss and increased aging. Investigators will test the applicability of the space environment as a model of aging skin. Noninvasive medical equipment will be ...
