Researchers at Nagoya University develop a composite material that, by adjusting its composition and exposing it to different types of light, can mimic animals' changes in color.

Nagoya, Japan - A range of creatures, including chameleons, octopuses, and frogs, can change color in response to changes in the environment. Some insights into the mechanisms behind this at the anatomical, cellular, and molecular levels have been obtained. However, much work is still required to obtain sufficient understanding of this phenomenon and to translate it into useful artificial applications.

In October 2015, two small minnows in the Lower Colorado River Basin -- the headwater chub and the roundtail chub -- were proposed for listing as threatened species under the Endangered Species Act of 1973. In April 2017, that proposal was withdrawn after new science identified the two small fish as members of the same species.

As technologies advance, genetic research is playing an increasingly important role in informing decisions about the conservation of threatened and endangered species. In addition to the roundtail chub, another recent example is the Mexican wolf.

The risk of preterm infants developing necrotizing enterocolitis (NEC) is higher when they are fed formula than when they feed on breast milk. Of the many reasons why breast milk protects preterm infants from this serious condition better than formula, not all of them are well understood.

Myotonic dystrophy type 1 (DM1) is the most common adult-onset muscular dystrophy that affects multiple organ systems. People with this condition develop progressive muscle wasting and weakness in their lower legs, hands, neck and face. Their muscles feel stiff and tight, causing them to be slow to relax certain muscles and therefore have difficulty releasing the hand from a handshake or a doorknob. In addition, people with this condition may have fatigue, muscle pain, difficulty swallowing, cataracts, irregularities in their heartbeat and respiratory complications.

Tuesday, June 26st, Rockville, MD - Today, Insilico Medicine, Inc., a Rockville-based next-generation artificial intelligence company specializing in the application of deep learning for target identification, drug discovery and aging research announces the publication of a new research paper "Reinforced Adversarial Neural Computer for De Novo Molecular Design" in The Journal of Chemical Information and Modeling.

A recent study found that online responses to female presenters in TEDx and TED-Ed videos were more polarized than responses to male presenters.

In an article in top journal PLOS ONE, Brigham Young University education professors Royce Kimmons and Ross Larsen, along with three other co-authors, found that though most comments on TEDx and TED-Ed videos are neutral, women receive more of both positive and negative comments than men.

Scientists at UT Health San Antonio have edited a gene in the brain to decrease the repetitive behaviors of mice with fragile X syndrome, which is an inherited cause of autism spectrum disorders. The study is described in the July issue of Nature Biomedical Engineering.

The San Antonio researchers, who included study leader Hye Young Lee, Ph.D, and first author Bumwhee Lee, Ph.D., used nanoparticle carriers developed in California to inject a gene-editing enzyme called Cas9 into the striatum, a brain region associated with formation of habits.

Philadelphia, June 26, 2018 - Poor sleep quality appears to be an important risk factor for atrial fibrillation, report scientists in the first study of its kind to demonstrate a relationship between poor sleep quality independent of sleep apnea and a higher risk of atrial fibrillation (AF). Their findings are published in HeartRhythm.

Refraining from bad behavior toward a significant other during stressful life events is more important than showing positive behavior, according to a Baylor University study.

Compared with positive gestures, negative ones tend to trigger more intense and immediate responses, according to the study. And how a couple works together during trying times is associated with individual well-being as well as satisfaction with the relationship.

Engineers work in quantifiable realism--an object exists and can be measured. Sometimes, though, the certainty of the object and how it will behave wavers. Researchers from the Automatic Control and System Dynamics Laboratory at the Technische Universität Chemnitz in Germany are starting to close the gap between reality and mathematical uncertainty.

HAMILTON, ON, June 25, 2018 - Clusters of stars across the vast reaches of time and space of the entire universe were all created the same way, researchers at McMaster University have determined.

Researchers Corey Howard, Ralph Pudritz and William Harris, authors of a paper published June 25 in the journal Nature Astronomy, used highly-sophisticated computer simulations to re-create what happens inside gigantic clouds of concentrated gases known to give rise to clusters of stars that are bound together by gravity.

Immune cells commonly blamed in Alzheimer's and other neurodegenerative diseases are actually precision cleaning machines protecting the central nervous system, new research from the University of Virginia School of Medicine shows.

The discovery adds nuance and complexity to our understanding of immune cells known as microglia. By appreciating the role of these cells in full, scientists are better positioned to develop new treatments and tailor medicine to individual patients' needs.

In a quiet courtroom, an attorney steps up to a lectern to deliver a closing argument. The defendant in the case is charged with murder, having stabbed a woman to death in front of her infant child.

"He beat her in the face," the attorney says, pounding a fist on the lectern, voice rising. After killing the victim, the defendant "ran from the apartment, and left behind one-year-old Kendall, alone with his mother's body."

A plaster which sticks to the inside of your mouth is revolutionising the treatment of painful recurring ulcers.

Scientists from the University of Sheffield's School of Clinical Dentistry, working in close collaboration with Dermtreat A/S from Copenhagen, have developed a unique patch using special polymers which are able to stick to moist surfaces.

The patch successfully administers steroids directly to oral ulcers or lesions whilst also creating a protective barrier around the affected area, accelerating the healing process.

A novel concept for a biosensor of the metabolite known as lactate, combines an electron transporting polymer with lactate oxidase, which is the enzyme that specifically catalyzes the oxidation of lactate. Lactate is associated with critical medical conditions so its detection is important for healthcare.
