Stretchable electronics a 'game changer' for stroke recovery treatment

Saturday February 17th, 2018 11:48:37 PM
A first-of-its-kind sensor that sticks to the throat and measures speech and swallowing patterns could be a game-changer in the field of stroke rehabilitation.

Newborn babies who suffered stroke regain language function in opposite side of brain

Saturday February 17th, 2018 11:48:34 PM
A stroke in a baby -- even a big one -- does not have the same lasting impact as a stroke in an adult. A study found that a decade or two after a 'perinatal' stroke damaged the left 'language' side of the brain, affected teenagers and young adults used the right sides of their brain for language.

Ultrathin, highly elastic skin display developed

Saturday February 17th, 2018 11:48:31 PM
A new ultrathin, elastic display that fits snugly on the skin can show the moving waveform of an electrocardiogram recorded by a breathable, on-skin electrode sensor. Combined with a wireless communication module, this integrated biomedical sensor system -- called 'skin electronics' -- can transmit biometric data to the cloud.

To sleep, perchance to forget

Saturday February 17th, 2018 11:48:28 PM
People and other animals sicken and die if they are deprived of sleep, but why is sleep so essential? Psychiatrists proposed the 'synaptic homeostasis hypothesis' (SHY) in 2003. This hypothesis holds that sleep is the price we pay for brains that are plastic and able to keep learning new things. A few years ago, they started research that could show direct evidence for their theory. The result offers visual proof of SHY.

Asteroid 'time capsules' may help explain how life started on Earth

Saturday February 17th, 2018 11:48:24 PM
In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs -- and offer an extraterrestrial source for mineral mining. But for one researcher, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system. Having that information gives scientists the starting point they need to reconstruct the complex pathway that got life started on Earth.

Personalized curriculum captures students' imagination, interest

Saturday February 17th, 2018 11:48:20 PM
Focusing on their personal DNA and genealogies, middle school students appear to have learned as much as their peers who used case studies, according to a researcher.

Illegal global trade of pangolins

Saturday February 17th, 2018 04:39:16 PM
Animal traffickers are taking advantage of remote ivory trade routes to smuggle pangolins – one of the world’s most endangered animals – out of Central Africa, a new study has found.

Unprecedented study of Picasso's bronzes uncovers new details

Saturday February 17th, 2018 04:36:48 PM
Scientists have completed the first major material survey and study of the Musee national Picasso-Paris' Pablo Picasso bronzes using portable instruments. They used the instruments and a database of alloy 'fingerprints' to non-invasively analyze a group of 39 bronzes and 11 painted sheet metal sculptures, revealing new details about the modern master's art.

Research team uncovers hidden details in Picasso Blue Period painting

Saturday February 17th, 2018 04:36:45 PM
Scientists have used multiple modes of light to uncover details hidden beneath the visible surface of Pablo Picasso's painting 'La Miséreuse accroupie', a major work from the artist's Blue Period. The researchers found images connected to other works by Picasso as well as a landscape -- likely by another Barcelona painter -- underneath Picasso's painting.

Scientists shed light on biological roots of individuality

Friday February 16th, 2018 10:47:38 PM
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.

Increasing incidence of rare skin cancer

Friday February 16th, 2018 10:46:58 PM
While it may not be as common as other skin cancers, Merkel cell carcinoma is highly aggressive and often deadly — and according to new research, it’s also becoming more common.

Shot may help shield against shingles

Friday February 16th, 2018 10:46:56 PM
Two vaccines are available to help prevent shingles, which can affect anyone who has had chickenpox or the chickenpox vaccine; both diseases are caused by the same virus, which stays in the body after chickenpox clears.

Progress in pursuit of sickle cell cure

Friday February 16th, 2018 08:03:41 PM
Bioengineers use gene editing to correct the mutation responsible for sickle cell disease in up to 40 percent of patients' cells used for lab testing.

Cells communicate in a dynamic code

Friday February 16th, 2018 08:03:38 PM
Scientists discover an unexpectedly dynamic vocabulary for the language of cellular communication.

Why we have yet to find extraterrestrial life

Friday February 16th, 2018 07:27:12 PM
Are we alone in the universe? Few questions have captured the public imagination more than this. Yet to date we know of just one sample of life, that which exists here on Earth.

Major discovery in controlling quantum states of single atoms

Friday February 16th, 2018 07:27:09 PM
The scientists identified which mechanisms destroy the quantum properties of individual insulator. Using a Scanning Tunneling Microscope, which utilizes an atomically sharp metal tip, they were able to precisely image individual iron atoms and measure and control the time that the iron atom can maintain its quantum behavior.

Humans will actually react pretty well to news of alien life

Friday February 16th, 2018 07:27:05 PM
Hollywood has it wrong. Humans would actually react positively to news of alien life -- intelligent or microbial.

Pilot study in Kenya shows link between chronic pain and glutamate consumption

Friday February 16th, 2018 07:27:02 PM
Preliminary research from a small pilot study carried out in Meru, in eastern Kenya, shows a link between chronic pain and consumption of glutamate, a common flavor enhancer found in Western and non-Western diets worldwide.

Lab-grown human cerebellar cells yield clues to autism

Friday February 16th, 2018 07:26:59 PM
Increasing evidence has linked autism spectrum disorder (ASD) with dysfunction of the brain's cerebellum, but the details have been unclear. In a new study, researchers used stem cell technology to create cerebellar cells known as Purkinje cells from patients with tuberous sclerosis complex (TSC), a genetic syndrome that often includes ASD-like features.

Immune signature predicts asthma susceptibility

Friday February 16th, 2018 07:26:56 PM
Asthma is a chronic inflammatory disease driven by the interplay of genetics, environmental factors and a diverse cast of immune cells. Researchers have now identified a subset of T cells, whose frequency serves as early childhood immune signature that predicts the risk of developing asthma later on.
