After platelet-rich plasma injections, researchers have described the structural change in the healing process as well as improvement in patients' pain and function, in a new report.
Neuroscientists show for the first time that PET scans can track the progression of Alzheimer's disease. In doing so, they also shed light on tau and beta amyloid, two key proteins associated with the neurodegenerative disorder.
As Apple and the FBI battle out the future of encryption, the inventors of public key encryption receive the highest computer science award in the world. The post Encryption Pioneers Win Computing's Most Prestigious Award appeared first on WIRED.
An anonymous reader writes: UK culture secretary John Whittingdale has announced that the British government will set up a 'round-table' between online publishers and adblocking companies to discuss the 'problem' of adblocking. He described the practice of charging companies to be whitelisted as a 'modern day protection racket', and said: "Quite simply – if people don't pay in some way for content, then that content will eventually no longer exist And that's as true for the latest piece of journalism as it is for the new album from Muse." The issue has largely been left to the market to self-regulate until now, although Germany's courts ruled adblocking legal in 2015.

Houston, they're back. After a yearlong mission to the International Space Station, American astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko have finally returned to their home planet.
Scientists have developed a process that improves the efficiency of CRISPR, an up-and-coming technology used to edit DNA. CRISPR is a groundbreaking technology that allows scientists to modify genes.
New technologies to improve memory in people with traumatic brain injury, mild cognitive impairment, epilepsy, and Alzheimer’s disease have been developed by scientists.
The unique properties of metamaterials have been used to cloak objects from light, and to hide them from vibration, pressure waves and heat. Now, a researcher wants to add another use for metamaterials: creating a new directional separation technique that cloaks one compound while concentrating the other.
serviscope_minor writes: The OpenBSD people forked and heavily cleaned up OpenSSL to create LibreSSL due to dissatisfaction with the maintainance of OpenSSL, culminating in the heartbleed bug. The emphasis has been on cleaning up the code and improving security, which includes removing things such as SSL2 which has fundamental security flaws. As a result, LibreSSL is not affected by the DROWN bug. LibreSSL is largely compatible with OpenSSL. The main exceptions are in the cases where programs use insecure functions removed from libreSSL, or require bug compatiblity with OpenSSL.

Inspired by nature, researchers are pioneering the use of simple sugars to power chemical reactions. It means that industries such as pharmaceuticals and agro-chemicals will have a renewable, inexpensive and non-toxic method of catalysis.
State laws mandating influenza immunization for people who work in health care increase their vaccination rates, according to new research. From 2000 to 2005, only Maine and New Hampshire had flu vaccine requirement laws for health care workers. During that period, the average flu vaccination rate for health care workers was 22.5 percent. From 2006 to 2011--when 19 other states, including Pennsylvania, passed similar laws--the average vaccination rate for health care workers increased to 50.9 percent.
One of the key components in a vaccine is an adjuvant, which serves to enhance our body's immune response to vaccination. Adjuvants have been around for almost a century however it is only recently that scientists are beginning to fully understand how they work.
Is cellphone use detrimental to mental health? A new study finds that addiction to, and not simply use of, mobile technology is linked to anxiety and depression in college-age students.
Diabetes is a significant global health problem, afflicting 382 million people worldwide with increasing prevalence rates and adverse effects on health, wellbeing, and society in general. Experts from around the world have synthesized a core set of recommendations using information from 14 countries as a basis in order to work towards optimizing diabetes care globally -- a critically important initiative to help stem the diabetes epidemic.
Carbon nanotubes may improve longevity in nuclear reactors, report scientists. For now, the method has only proved effective for aluminum, which limits its applications to the lower-temperature environments found in research reactors. But the team says the method may also be usable in the higher-temperature alloys used in commercial reactors.
Ovarian cancer should not be categorized as a single disease, but rather as a constellation of different cancers involving the ovary, yet questions remain on how and where various ovarian cancers arise, says a new congressionally mandated report.
Organic photovoltaics bear great potential for large-scale, cost-effective solar power generation. One challenge to be surmounted is the poor ordering of the thin layers on top of the electrodes. Utilizing self-assembly on atomically flat, transparent substrates, a team of scientists has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabrication of optoelectronic devices with molecular precision.
Did you know the CRISPR/Cas9 system was derived from bacteria, which use it to fight off foreign invaders such as viruses? It allows many bacteria to snip and store segments of DNA from an invading virus, which they can then use to 'remember' and destroy DNA from similar invaders if they are encountered again. Recent work demonstrates that some bacteria also use the CRISPR/Cas system to snip and recognize segments of RNA, not just DNA.
GEMC1 has been identified as a master gene for the generation of multiciliated cells -- cells with fine filaments that move fluids and substances -- which are found exclusively in the brain, respiratory tract, and reproductive system. Defects in multiciliated cells lead to ciliopathies -- rare and complex diseases that are poorly understood and for which not all causative genes have been identified.
Teens who are homeschooled benefit from healthier sleep habits than those who go to most private and public schools, a new study has concluded, the first of its kind. The findings provide additional evidence of teens' altered biological clocks and support an argument for starting traditional high school later in the morning.
