A low-cost therapy can improve the lives of stroke patients with vision problems, investigators have found.
When a material is made, you typically cannot change whether that material is hard or soft. But a group of researchers have developed a new way to design a 'metamaterial' that allows the material to switch between being hard and soft without damaging or altering the material itself.
Yoga and aerobic exercise interventions did not significantly reduce objectively measured sleep disturbances among midlife women who were experiencing hot flashes, suggests new research.
Currently, most scientists do not see a link between ALS and Alzheimer's disease, frontotemporal dementia (FTD), or other dementias. New research confirms the relevance of a certain neurotoxic pathway. The article also confirms TDP-43 inhibition as a viable therapeutic option for the treatment of neurologic disorders, including Alzheimer disease.
A new preclinical study shows that vagus nerve stimulation therapy might have the potential to help people overcome drug addiction by helping them learn new behaviors to replace those associated with seeking drugs.
A new study is the first to explore racial factors and how they may influence attitudes and behaviors towards the flu vaccine.
There are important, long-term gains from hastening the processes around surgical interventions against epilepsy -- before the disease has had too much negative impact on brain functions and patients' lives. These are some of the findings of a thesis for which more than 500 patients were studied and followed up.
Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an ocean area may seem like a good predictor for the amount of fish that can be caught there, but a new study finds that this relationship is not so straightforward.
Unbalanced signaling by two molecules that regulate breathing leads to sleep apnea in mice and rats. Injection of a substance that reduces production of one of those signals can prevent apneas. This approach may help people suffering from multiple forms of sleep-disordered breathing.
A novel mechanism has been identified for how stress-induced anxiety -- which can produce post-traumatic stress disorder, or PTSD -- affects circuit function in the hippocampus, the area of the brain where aversive memories are formed. These studies fill an important gap in knowledge between the molecular, circuit and behavioral effects of the brain-signaling molecule called neuropeptide Y, and could lead to new therapeutic targets for patients with anxiety disorders.
Online media use such as social networking and gaming could be strongly influenced by our genes, according to a new study.
By determining the three-dimensional structures of these molecules down to the level of atoms, the researchers have unlocked key details as to how they function in the body.
Non-indigenous species are harming indigenous species and habitats in the Mediterranean Sea, impairing potentially exploitable marine resources and raising concern about human health issues, according to a new study.
A team of researchers, including a mathematician, has determined how Arctic melt ponds form, solving a paradoxical mystery of how a pool of water actually sits atop highly porous ice.
Utilizing the most rigorous testing methods to date, researchers have isolated additional collagen peptides from an 80-million-year-old Brachylophosaurus.
The protein PHLDB3, thought to be a potential tumor suppressor, actually allows cancer cells to thrive in pancreatic, prostate, colon, breast, lung, and other common cancers, researchers have found. The discovery could explain how cancer is able to overcome p53 -- a key tumor-suppressing protein.
A team of astronomers has discovered seven distinct groups of dwarf galaxies with just the right starting conditions to eventually merge and form larger galaxies, including spiral galaxies like the Milky Way.
A landmark clinical trial is evaluating a new procedure to treat a life-threatening heart rhythm disorder called ventricular tachycardia.
Unmasking a previously misunderstood gene, scientists discover an unlikely potential drug target for gastrointestinal cancers.
Tiny 'submarines' that speed independently through the stomach, use gastric acid for fuel (while rapidly neutralizing it), and release their cargo precisely at the desired pH: Though it may sound like science fiction, this is a new method for treating stomach diseases with acid-sensitive drugs. The technique is based on proton-driven micromotors with a pH-dependent polymer coating that can be loaded with drugs.
