Young athletes who do not achieve a 90 percent score on a battery of tests that measure fitness to return to athletic competition, including quadricep strength, are at increased risk for a second knee injury, according to research presented at the Annual Meeting of the American Orthopedic Society of Sports Medicine.

Chronic itch goes beyond being just a simple annoyance; it can greatly affect a person's quality of life. While scientists have some clues to its causes, effective therapies have been elusive.

Many dinosaur species are known from scant remains, with some estimates suggesting 75% are known from five or fewer individuals. Auroraceratops rugosus was typical in this regard when it was named in 2005 based upon a single skull from the Gobi Desert in northwestern China. But that is no longer the case.

Most non-traumatic fatalities among high school and college football athletes do not occur while playing the game of football, but rather during conditioning sessions which are often associated with overexertion or punishment drills required by coaches and team staff, according to research presented today at the American Orthopedic Society for Sports Medicine Annual Meeting. The research was presented by Dr. Barry P. Boden of The Orthopaedic Center, Rockville, Md.

Professional baseball players with a low-grade elbow injury that occurs on the humeral side of the elbow have a better chance of returning to throw and returning to play, and a lower risk of ulnar collateral ligament surgery than players who suffered more severe injuries on the ulnar side of the elbow. The research was presented at the Annual Meeting of the American Orthopedic Society of Sports Medicine.

The internet has its perils with privacy breaches and fake news, but on the plus side, a whole generation of youth have been teaching themselves skills in leadership and community-building, according to a new University of California, Davis, study.

Washington, DC - July 12, 2019 - Surgical gowns and stainless steel remained contaminated with the pathogen Clostridium difficile even after being treated with the recommended disinfectant. The research is published July 12 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

A study of up to 4.4m adult participants has shown that those who were born pre-term (under 37 weeks gestation) are less likely to form romantic relationships, have sexual relations or experience parenthood than those who were born full term

Research from the University of Warwick suggests it's partly due to pre-term birth being associated with being more often withdrawn and shy, socially excluded and less likely to take risks in adolescence

UV detection stickers trialled by Queensland University of Technology (QUT) researchers at the November 2017 Ashes Test at the Gabba have scored with cricket fans.

The stickers, some of which were tagged with Cricket Australia's official 2017 campaign hashtag #BeatEngland, contained UV-sensitive ink which changes colour to warn people when the effect of their sunscreen is wearing off and it needs to be reapplied.

Also known as blue-green algae, cyanobacteria are a special class of bacteria that are able to perform photosynthesis. In evolutionary terms, they are ancient. Their predecessors - which first emerged on earth some 2.5 billion years ago - paved the way for higher forms of life thanks to their ability to produce oxygen by photosynthesis.

A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: they move through a material in a well ordered manner that practically never lets them collide with each other and is thus very energy efficient. This opens up intriguing possibilities for the electronics of the future. Up to now, Weyl fermions had only been found in certain non-magnetic materials.

Two proteins that activate the fastest molecule in our nerve cells identified by researchers at University of Warwick

Mechanism is responsible for transport through our nervous system

Faults in cargo transporters can lead to hereditary spastic paraplegia (HSP) and other neurodegenerative disorders

Could lead to therapeutic treatment for people with HSP and neurological disorders

Scientists at the University of Warwick have discovered a new process that sets the fastest molecular motor on its marathon-like runs through our neurons.

The temperature sensitivity of soil organic matter (SOM) decomposition, commonly referred to as Q10, is a key parameter in the terrestrial carbon cycle. It quantifies the increase in the rate of decomposition corresponding to a 10oC rise in temperature and can determine the sign and magnitude of terrestrial carbon-climate feedback.

Scientists at the Basque research centre BCBL conclude that the voice is fundamental for mentally presenting the meaning of words in the brain. This finding implies a greater knowledge about how sound waves bring additional information to words.

For years, neuroscientists have been trying to find out whether the voice influences the processing of information or whether we understand a word in one way or another depending on who pronounces it.

Lobachevsky University scientists together with their colleagues from the National Research Center "Kurchatov Institute" (Moscow) and the National Research Center "Demokritos" (Athens) are working on the hardware implementation of a spiking neural network based on memristors. The key elements of such a network, along with pulsed neurons, are artificial synaptic connections that can change the strength (weight) of connection between neurons during the learning.
