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.

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 ...

EMBL’s European Bioinformatics Institute (EMBL-EBI) has launched the Global Biodiversity Portal – an open access data portal that will consolidate genomic information from different biodiversity projects within the Earth BioGenome Project.  Sequencing and storing the genomic data of all species on Earth is vital for future conservation and biodiversity efforts. In an era where biodiversity is under threat from various environmental pressures, there is an urgent need for centralised, accessible, and actionable data. ...

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. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle. CHEOPS is a joint mission by ESA and Switzerland, under the leadership of the University of Bern in collaboration with the University of Geneva. Thanks to a collaboration with scientists ...

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 ...

ST. LOUIS – Each year, tuberculosis (TB) kills more people than any other infectious disease, falling out of the top spot only temporarily during the COVID-19 pandemic. Despite TB’s wide reach and some lost progress during the COVID-19 pandemic, researchers believe it is possible to eradicate TB through advances in vaccine development and public health. To cross the finish line, scientists must find ways to test new vaccines rapidly to prevent TB infections more effectively. In a paper published in the Journal of Infectious Diseases, Daniel Hoft, M.D., Ph.D., ...

Two papers recently published in Environmental Toxicology and Chemistry have made important advancements toward understanding the effects of perfluorooctane sulfonate (PFOS) on aquatic life, especially fish. Zebrafish had been identified in a previous study of limited scope as being among one of the most sensitive aquatic species to PFOS, and the results of that limited-scope study have influenced PFOS water quality criteria derived by some regulatory agencies, including the Australian Environmental Protection Agency (EPA). Kurt Gust and ...

(LOS ANGELES) – November 29, 2023 - Scientists from the Terasaki Institute for Biomedical Innovation (TIBI) have developed an injectable or catheter-administered hydrogel with enhanced capabilities for treating hepatocellular carcinoma (HCC), a deadly form of liver cancer. As described in their recent publication in Advanced Functional Materials, this drug-eluting hydrogel can provide sustained, pH-dependent drug co-delivery and has capabilities for promoting anti-tumor immune responses. This reduces tumor cell proliferation and growth and offers a more efficient means of enabling tumor cell death. Worldwide, HCC is a leading cause of ...

Optoelectronics detect or emit light and are used in a variety of devices in many different industries. These devices have historically relied on thin transistors, which are small semiconductors that control the movement of electrons and photons, made out of graphene and other two-dimensional materials. However, graphene and these other materials often have problems with band gap opening and other shortcomings that have researchers searching for an alternative.   When treated with a method called the ...

Recent findings at Cold Spring Harbor Laboratory (CSHL) shine a new light on pancreatic cancer. More than 90% of pancreatic cancer cases are attributed to an aggressive, deadly form of the disease called pancreatic ductal adenocarcinoma, or PDAC. Researchers have a poor understanding of how our immune system interacts with PDAC. So, coming up with treatments is tricky. It’s thought patients do not show a natural immune response to the cancer because the tumor environment somehow prevents that response. Many are unconvinced that PDAC ...

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. According to research published in ACS Central Science, the simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, star-forming regions of the universe. It has long been hypothesized that one of the building blocks for life, amino acids, could have formed during reactions in the “primordial ...
