Published Lost brain function restored in mice after stroke (via sciencedaily.com) Original source
Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy.
Published Common headaches tied to neck inflammation (via sciencedaily.com) Original source
Researchers have identified objective evidence of how the neck muscles are involved in primary headaches, according to a new study.
Published Fat cells help repair damaged nerves (via sciencedaily.com) Original source
Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process.
Published Repairing nerve cells after injury and in chronic disease (via sciencedaily.com) Original source
Researchers discovered a mechanism for repairing damaged nerves during peripheral neuropathy in mice, wherein the protein Mitf orchestrates nerve repair after both trauma-induced and chronic nerve damage conditions, like Charcot Marie Tooth disease. Their findings may inspire novel therapeutics that bolster repair function and heal peripheral neuropathy -- even in hereditary and developmental cases.
Published Getting to the root of visceral gut pain (via sciencedaily.com) Original source
Researchers have uncovered a reason that may explain why visceral pain is so common in conditions like irritable bowel syndrome. This understanding could inspire new and better ways to alleviate that pain.
Published Wearables capture body sounds to continuously monitor health (via sciencedaily.com) Original source
From heart beats to stomach gurgles, sounds hold important health information. New wireless devices sit on skin to continuously capture these sounds, then stream data to smartphones or tablets in real time. In pilot studies, devices accurately tracked sounds associated with cardiorespiratory function, gastrointestinal activity, swallowing and respiration. The devices are particularly valuable for premature babies, who can experience apneas and gastrointestinal complications, which are accompanied by sounds.
Published When we see what others do, our brain sees not what we see, but what we expect (via sciencedaily.com) Original source
When we engage in social interactions, like shaking hands or having a conversation, our observation of other people's actions is crucial. But what exactly happens in our brain during this process: how do the different brain regions talk to each other? Researchers provide an intriguing answer: our perception of what others do depends more on what we expect to happen than previously believed.
Published New compound outperforms pain drug by indirectly targeting calcium channels (via sciencedaily.com) Original source
A compound -- one of 27 million screened in a library of potential new drugs -- reversed four types of chronic pain in animal studies, according to new research. The small molecule, which binds to an inner region of a calcium channel to indirectly regulate it, outperformed gabapentin without troublesome side effects, providing a promising candidate for treating pain.
Published New AI noise-canceling headphone technology lets wearers pick which sounds they hear (via sciencedaily.com) Original source
Researchers have developed deep-learning algorithms that let users pick which sounds filter through their headphones in real time. Either through voice commands or a smartphone app, headphone wearers can select which sounds they want to include from 20 classes, such as sirens, baby cries, speech, vacuum cleaners and bird chirps.
Published How animals get their stripes and spots (via sciencedaily.com) Original source
New research helps explain how sharp patterns form on zebras, leopards, tropical fish and other creatures. Their findings could inform the development of new high-tech materials and drugs.
Published Disturbances in sensory neurons may alter transient pain into chronic pain (via sciencedaily.com) Original source
Researchers have identified that a transient inflammatory pain causes mitochondrial and redox changes in sensory neurons that persist beyond pain resolution. These changes appear to predispose to a failure in resolution of pain caused by a subsequent inflammation. Additionally, targeting the cellular redox balance prevents and treats chronic inflammatory pain in rodents.
Published Want the secret to less painful belly flops? These researchers have the answer (via sciencedaily.com) Original source
Researchers investigated belly flop mechanics and found surprising insights about air-to-water impacts that could be useful for marine engineering applications. They set up a belly flop-like water experiment using a blunt cylinder but added an important vibrating twist to it.
Published How 'blue' and 'green' appeared in a language that didn't have words for them (via sciencedaily.com) Original source
A new study suggests the way a language divides up color space can be influenced by contact with other languages. Tsimane' people who learned Spanish as a second language began to classify blue and green into using separate words, which their native tongue does not do.
Published Lab unlocks keys to alcohol withdrawal headache (via sciencedaily.com) Original source
Researchers have discovered mechanisms by which specific cells are activated in alcohol withdrawal-induced headache. The research may benefit further studies of various substance use disorder mechanisms including withdrawal. It may be possible to develop a small-molecule drug therapy to inhibit interactions, resulting in fewer pain signals during alcohol withdrawal.
Published Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants (via sciencedaily.com) Original source
DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes (via sciencedaily.com) Original source
Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published New study provides evidence for more effective brain-based treatment of chronic back pain (via sciencedaily.com) Original source
A new study may provide key answers to how to help people experiencing chronic back pain. The study examined the critical connection between the brain and pain for treating chronic pain. Specifically, they looked at the importance of pain attributions, which are people's beliefs about the underlying causes of their pain, to reduce chronic back pain severity.
Published Researchers 'bioprint' living brain cell networks in the lab (via sciencedaily.com) Original source
Researchers have successfully used 'bioinks' containing living nerve cells (neurons) to print 3D nerve networks that can grow in the laboratory and transmit and respond to nerve signals.
Published Your body's own cannabinoid molecules calm you during stress (via sciencedaily.com) Original source
When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
Published Lower jersey numbers make football players look thinner (via sciencedaily.com) Original source
Football players sometimes choose jerseys with lower numbers thinking that they'll look slimmer and faster. There's a scientific basis for that belief, according to a new study. In two experiments, volunteers consistently said that images of players in jerseys numbered 10 to 19 looked thinner than players in jerseys numbered 80 to 89, even when the bodies were the same size. The finding suggests that people's previously learned associations between numbers and sizes influence their perceptions of body size.
