Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
The term sexting has been used to describe incidents where people take nude or semi-nude photos or videos of themselves and exchange that content via text or private social media messages. To adults it is recognized as somewhat ridiculous but at least there is the pretense of mature consent, that it is only being shared with trusted romantic partners, while with teens there is concern these images will find their way into the hands of others and follow them throughout their early lives at a time when everything is already dramatic.
As the Apollo 11 Lunar Module approached the moon's surface for the first manned landing, commander Neil Armstrong switched off the auto-targeting feature of the LM's computer and flew the spacecraft manually. A new video, created at Arizona State University's School of Earth and Space Exploration, shows what Armstrong saw out his window as the lander descended — and that means we can see for yourself why he took control. They used the crew's voice recording, the timings, a video taken on film and images taken from lunar orbit by the LROC over the last 10 years.
Optogenetics biotechnology, using light to manipulate neurons so that they can be turned on or off, has led to a device that replicates the way the brain stores and loses information.The new chip is based on an ultra-thin material that changes electrical resistance in response to different wavelengths of light, enabling it to mimic the way that neurons work to store and delete information in the brain.
New efforts by the FDA and coastal cities to kill off e-cigarettes with bans and restrictions will drive existing users to smoke more cigarettes, according to new research from Duke Health.
The findings, from a survey of 240 young U.S. adults who use both e-cigarettes and traditional tobacco cigarettes, are scheduled to be published July 15 in the journal Substance Use & Misuse.
The online survey asked participants aged 18 to 29 to predict their use of two products they already used -- e-cigarettes and traditional tobacco cigarettes -- in response to hypothetical regulations to limit e-cigarette flavors, limit the customizability of e-cigarettes or eliminate the nicotine in e-cigarettes.
An antibody is an agent of the immune system that attaches to an antigen. Usually antibodies recognize antigens on a virus or bacteria and attach to the invader to mark it for destruction by other immune cells. In a new study, University of Colorado Anschutz researchers engineered an antibody to recognize and attach to a protein called EGFR. Bladder tumors (but not healthy cells) are often covered in EGFR. Other researchers have hooked molecules of chemotherapy to antibodies that recognize EGFR and have used this antibody-antigen system to micro-target the delivery of chemotherapy. In this case, researchers used nifty chemistry to attach gold nanoparticles to antibodies.
In April 2017, journalists promoted a claim about plastic bag eating caterpillars which led to sensationalistic coverage in worldwide media. They could eat the sea-sized floating islands of plastic bags that don't actually exist.The science community was skeptical.
An analysis of a 160,000-year-old archaic human molar fossil discovered in China points to a different evolutionary path a rare trait primarily found in modern Asians than previously accepted timelines after Homo sapiens dispersed from Africa.The study centers on a three-rooted lower molar and reveals the first morphological evidence of interbreeding between H. sapiens and the Denisovans, a sister group of Neanderthals.
Black-eyed peas, a global dietary staple for centuries due to their environmental toughness and nutritional qualities, are small beans with dark midsections. In sub-Saharan Africa they remain the number one source of protein in the human diet. Now it's gotten its genome decoded, a problem almost as tough as the legume itself. A genome is the full collection of genetic codes that determine characteristics like color, height, and predisposition to diseases. All genomes contain highly repetitive sequences of DNA that University of California Riverside Professor of Computer Science Stefano Lonardi likens to "hundreds of thousands of identical jigsaw puzzle pieces."
Kratom, derived from the leaves of the southeast Asian tree Mitragyna speciosa, is a supplement that is not useless, it actually does something. It contains psychoactive compounds and users also like it as an analgesic, but because it is a plant users and kratom trade groups insist it should not have to go through clinical trials, even while they sell it as a product that is a drug.
Fish, insects, crustaceans, and even some plants possess the ability to change the sex of their offspring before they are born. It's a genetic skill mammals lack. Or did.A new study reveals a genetic system in mammals that enables two animals to mate and produce only females. A similar system based on identical principles would produce only males.This proof of concept is in mice - an instance where a mouse study is actually valid - but the real benefit is for agriculture, where farmers may want dairy cows and egg-laying chickens and not have to deal with random chance.
There is no question the government and its hand-picked advisors have hyped claims of opioid addiction beyond all sense. Doctors, pharmaceutical companies, and legitimate pain patients have all been steamrolled in an effort to stop what is really a recreational use problem.
Data from the Youth Risk Behavior Surveys between 1993 to 2017 covering 27 states and Washington, D.C., before and after "medical" marijuana laws were adopted and 7 states from before and after recreational marijuana laws were adopted covering more than 1.4 million high school students finds that marijuana laws appear to be associated with a decrease in the odds of marijuana use in the past 30 days or frequent marijuana use after medical marijuana laws were passed.
