Their conclusion: both types of IUDs are very safe and, compared to condoms or the pill, cost-effective contraceptive ...

Optical wireless may no longer have any obstacles. A study by Politecnico di Milano, conducted together with Scuola Superiore Sant'Anna in Pisa, the University of Glasgow and Stanford University, and published in the prestigious journal Nature Photonics, has made it possible to create photonic chips that mathematically calculate the optimal shape of light to best pass through any environment, even one that is unknown or changing over time.   The problem is well known: light is sensitive to any form of obstacle, even very small ones. Think, for example, of how we see objects when looking through a frosted window ...

It’s one of those days. On the drive home from work, the car in the next lane cuts you off. You slam on the brakes, lay on the horn, and yell choice words at the offending driver. When you walk into your house half an hour later, you’re still angry, and snap at your partner when they ask about your day. Fruit flies may not have to worry about the lingering effects of road rage, but they also experience states of persistent aggression. In the case of female fruit flies, this behavior is a survival mechanism, causing the flies to headbutt, shove, and fence other female fruit flies to guard prime egg-laying territory on a ...

About The Study: Between 2010 and 2020, surgeon supply per 100,000 population decreased in rural counties and increased in urban counties, and decreased in socially vulnerable counties and remained unchanged in other counties. Thus, over the past decade, disparities in surgeon supply between rural and urban counties and between socially vulnerable and other counties have widened in the U.S. The largest widening was observed among general surgeons.  Authors: Vishal R. Patel, B.S., of the Dell Medical School in Austin, Texas, is the corresponding author.

New technology often calls for new materials – and with supercomputers and simulations, researchers don’t have to wade through inefficient guesswork to invent them from scratch.  The Materials Project, an open-access database founded at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) in 2011, computes the properties of both known and predicted materials. Researchers can focus on promising materials for future technologies – think lighter alloys that improve fuel economy in cars, more ...

The evolution of higher cognitive functions in human beings has so far mostly been linked to the expansion of the neocortex – a region of the brain that is responsible, inter alia, for conscious thought, movement and sensory perception. Researchers are increasingly realising, however, that the “little brain” or cerebellum also expanded during evolution and probably contributes to the capacities unique to humans, explains Prof. Dr Henrik Kaessmann from the Center for Molecular Biology of Heidelberg University. ...

A new study has confirmed that pesticides, commonly used in farmland, significantly harm bumblebees – one of the most important wild pollinators. In a huge study spanning 106 sites across eight European countries, researchers have shown that despite tightened pesticide regulations, far more needs to be done.  While the agricultural uses of insecticides have been in the spotlight for their negative effects on bees, it has remained unknown how the effects scale beyond single substances in focal ...

Embargoed until November 29 11 a.m. ET  A new study led by Dr. Annette Dekker, an assistant professor in the Department of Emergency Medicine at UCLA, calls for the U.S. Immigration and Customs Enforcement (ICE) detention centers to increase health outcome reporting for detained immigrants to monitor the quality of medical care. Pulling from three different data sources, the researchers found discrepancies in care reported by emergency medical services (EMS) compared to ICE reports.   Building upon work that reviews deaths that occur at ICE detention centers, Dekker and colleagues sought to address concerns that individuals detained by ICE ...

Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene – one allele per chromosome or parent. Both alleles are able to produce messenger RNA, which is the recipe needed to make proteins and keep cells running. Scientists hypothesize that having two alleles for each gene is the cell’s in-built redundancy system. If there is ever a mutation or drop in messenger RNA production from the allele carried on one of the chromosomes, the allele on the second chromosome will serve as a backup and ...

Scientists have discovered a rare sight in a nearby star system: Six planets orbiting their central star in a rhythmic beat. The planets move in an orbital waltz that repeats itself so precisely it can be readily set to music. A rare case of an “in sync” gravitational lockstep, the system could offer deep insight into planet formation and evolution. The analysis, led by UChicago scientist Rafael Luque, will be published Nov. 29 in Nature. “This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the ...

A marvel of modernity is the ability to collaborate with others regardless of location. Researchers can work with a colleague, maybe the only person who has a specialized skill, even if they are halfway across the globe. They can pull together a powerhouse team with a dozen of the brightest minds in the field. Yet, according to research from the lab of Lingfei Wu, assistant professor in Pitt’s School of Computing and Information, these collaborative teams are producing fewer truly disruptive ideas or radical innovations than ...

An international collaboration between astronomers using the CHEOPS and TESS space satellites, including NCCR PlanetS members from the University of Bern and the University of Geneva, have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm.

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe’s most energetic and mysterious light shows — gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an infant black hole surrounded by a giant disk of natal material. Astronomers previously thought that black holes that generate long GRBs typically form when massive ...

FOR IMMEDIATE RELEASE In a new study using brain scans of former NFL athletes, Johns Hopkins Medicine researchers say they found high levels of a repair protein present long after a traumatic brain injury such as a concussion takes place. The repair protein, known as 18 kDa translocator protein (TSPO), is known to be present in the brain at high levels in the immediate aftermath of brain injury as part of the inflammatory response and to facilitate repair. The new findings, published Oct. 30 in JAMA Network Open, suggest that brain injury and repair processes persist for years after players end collision sports careers, and lead to long-term cognitive ...

Quantum technologies are currently maturing at a breath-taking pace. These technologies exploit principles of quantum mechanics in suitably engineered systems, with bright prospects such as boosting computational efficiencies or communication security well beyond what is possible with devices based on today’s 'classical' technologies. As with classical devices, however, to realise their full potential, quantum devices will need to be networked. In principle, this can be done using the fibre-optic networks employed for classical telecommunications. But practical implementation requires that the information ...
