New metamaterial can switch from hard to soft -- and back again

14 hours 33 min ago
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.

Common cause of both neurological diseases such as dementia and motor neuron diseases

Mon, 23/01/2017 - 9:23pm
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.

Long-term gains with early epilepsy surgery

Mon, 23/01/2017 - 9:22pm
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.

From tiny phytoplankton to massive tuna

Mon, 23/01/2017 - 9:22pm
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.

Regulating gasotransmitters could improve care for sleep apnea

Mon, 23/01/2017 - 8:38pm
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.

Novel underlying mechanism involved in PTSD and other anxiety disorders described

Mon, 23/01/2017 - 8:14pm
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.

Tumor-suppressing protein actually promotes cancer

Mon, 23/01/2017 - 6:37pm
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.

Microscopic submarines for your stomach

Mon, 23/01/2017 - 5:55pm
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.
