Archaeologists say they've discovered the earliest known bone tools in Europe.

The actor and comedian decided it was time to have the procedure after he and his wife had had four children. Here he writes candidly about the experience, and why it was the kindest cutI got a vasectomy a few months ago. A vasectomy is when they cut and tie off the vas deferens, which are these little tubes in your ball sack (scrotum) so that there’s no sperm (sperm) in your jizz (semen) when...

CLEVELAND, Ohio (August 12, 2020)--Removal of the ovaries before natural menopause (surgical menopause) often exacerbates menopause symptoms and places women at increased risk for heart disease, osteoporosis, and cognitive decline. A new study identified the frequency of hormone therapy (HT) use and factors that determine who is more likely to use hormones after oophorectomy to manage symptoms....

New research on the popularity of Congress members' Instagram posts reveals some surprising factors at play that could elevate their influence on the platform and make for more effective campaigns.

When considering new products, anxiety creates approach response (i.e., interest, purchase) rather than avoidance response (i.e., disinterest, failure to purchase) when consumers hope for the goal-congruent outcomes.

Companies across the world are competing fiercely to provide high-resolution displays to electronic devices such as TVs and smartphones. In particular, the virtual reality, a keyword of the 4th industrial revolution, requires a much higher resolution to improve the picture quality. A Korean research team developed a technology to produce a 'nano display' with a phenomenal resolution based on the...

The Korea Institute of Science and Technology (KIST) announced that a research team led, by Dr. Hyungmin Kim at the Center for Bionics, Biomedical Research Institute of the KIST, found a strong correlation between a ultrasonic stroke rehabilitation method for treating damaged brain and a change in delta waves, which is a type of brain waves.

A compound given as a dietary supplement to overweight but otherwise healthy people in a clinical trial caused many of the patients to slim down.

Sleep paralysis - a condition thought to explain a number of mysterious experiences including alleged cases of alien abduction and demonic night-time visits - could be treated using a technique of meditation-relaxation, suggests a pilot study published today.

Ganesh Balasubramanian, P.C. Rossin assistant professor of Mechanical Engineering & Mechanics at Lehigh University, and his graduate student Joydeep Munshi demonstrated that adding small molecules to a semiconducting polymer blend enhances the performance and stability of material used in organic solar cells. The study is described in an article, 'Elasto-morphology of P3HT:PCBM bulk heterojunction...

Here, we demonstrate that 2D D-J perovskites experiencevarious transitions under pressure, such as crystalline-amorphous and 2D-three-dimensional structural transformation, and theprobable metallization are strongly suggested. Moreover, thefundamental changes in the material properties are observed at ambient conditions after pressure treatment, which is crucial for achieving the desired...

Research by INRS (Institut National de la Recherche Scientifique) Professor Salim Timo Islam has revealed that multicellular physiology in the social bacterium Myxococcus xanthus--a bacterium that can actively reorganize its community according to the environment in which it is found--is modulated by the secretion of two natural sugar polymers in separate zones of a swarm. Results from their...

Vaccination rates in the U.S. have plummeted amid COVID-19. A new national survey by Orlando Health finds while the vast majority of parents (84%) believe vaccines are the best way to protect their children from infectious diseases, two-thirds are still nervous to take their kids to their pediatrician's office due to COVID-19.

Researchers use spectroscopy to quickly and cheaply analyze soils samples.

Scientists have devised a novel approach to halting the spread of SARS-CoV-2, the virus that causes COVID-19. The researchers engineered a completely synthetic, production-ready molecule that straitjackets the crucial SARS-CoV-2 machinery that allows the virus to infect our cells. In an aerosol formulation they tested, these molecules could be self-administered with a nasal spray or inhaler.

Among former NFL players, Black, Hawaiian, and athletes from other racial backgrounds report worse physical, mental health outcomes than white players. The widest health gaps emerged between Black and white former NFL players. Black former players reported worse health outcomes in all five health categories, compared with their white peers. Presence of health disparities among former NLF players...

Researchers have used a natural plant product, called cellulose nanocrystals, to pin and coat carbon nanotubes uniformly onto the carbon-fiber composites. The researchers said their prescribed method is quicker than conventional methods and also allows the designing of carbon-fiber composites from the nanoscale.

New research finds a direct link between a country's incoming business travel and the growth of new and existing industries. The findings support a Growth Lab hypothesis that moving 'knowhow' is critical to economic growth, and business travel plays a key part in that process. The research also raises new concerns about the economic implications of the international travel restrictions imposed to...

A broken cable caused severe damage at Puerto Rico's Arecibo Observatory, causing a suspension of operations for one of the world's largest single-dish radio telescopes, officials said Tuesday.

The optical vortex plays an increasingly important role in optical information processing. As an information carrier, it improves the capacity of channels and offers an independent aspect for analysis—different from polarization, intensity, phase, and path. A new degree of freedom for encoding and encrypting optical information may be provided via nonlinear optics, using vortex beams known as...

According to research led by The University of Texas at Austin, seasonal rainfall is expected to rise significantly in East Africa over the next few decades in response to increased greenhouse gases.

Scientists at the University of Bath have taken an important step towards understanding the interaction between layers of atomically thin materials arranged in stacks. They hope their research will speed up the discovery of new, artificial materials, leading to the design of electronic components that are far tinier and more efficient than anything known today.

Millions of American homes could become unsellable—or could be sold at significant losses to their senior-citizen owners—between now and 2040, according to new research from the University of Arizona.

When survival over generations is the end game, researchers say it makes sense to undervalue long shots that could be profitable and overestimate the likelihood of rare bad outcomes.
