What The Study Did: This study analyzed changes in Medicaid enrollment for all 50 states and the District of Columbia during the first nine months of last year during the COVID-19 pandemic.

MIT biologists find cell extrusion, a process that helps organisms eliminated unneeded cells, is triggered when cells can't replicate their DNA during cell division. In humans, extrusion may serve as a way for the body to eliminate cancerous or precancerous cells.

Surgeons have historically been overwhelmingly white and male, and although there have been some diversity gains among junior positions, a JAMA Surgery study shows that representation of Black and Latinx surgeons at leadership levels has not improved over the past six years. And Black and Latina women, who are grappling with the intersectionality of race/ethnicity and gender, have it even worse.

The discovery of the earliest human burial site yet found in Africa, by an international team including several CNRS researchers1, has just been announced in the journal Nature. At Panga ya Saidi, in Kenya, north of Mombasa, the body of a three-year-old, dubbed Mtoto (Swahili for 'child') by the researchers, was deposited and buried in an excavated pit approximately 78,000 years ago

With the help of their custom-built super-resolution microscope, EPFL biophysicists have discovered where and why mitochondria divide, putting to rest controversy about the underlying molecular machinery of mitochondrial fission. Mitochondria either split in half or cut off their ends to self-regulate. The results are published in Nature.

The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study.

To improve diagnosis for patients with complex metastatic cancers, especially those in low-resource settings, researchers from the Mahmood Lab at the Brigham and Women's Hospital developed an artificial intelligence (AI) system that uses routinely acquired histology slides to accurately find the origins of metastatic tumors while generating a "differential diagnosis," for cancer of unknown primary patients.

The world is currently on track to exceed three degrees Celsius of global warming, and new research led by the University of Massachusetts Amherst's Rob DeConto, co-director of the School of Earth & Sustainability, shows that such a scenario would drastically accelerate the pace of sea-level rise by 2100. If the rate of global warming continues on its current trajectory, we will reach a tipping point by 2060, past which these consequences would be "irreversible on multi-century timescales."

A new study featured on the 6 May cover of Nature by an international team of researchers details the earliest modern human burial in Africa. The remains of a 2.5 to 3 year-old child were found in a flexed position, deliberately buried in a shallow grave directly under the sheltered overhang of the cave. The interment at Panga ya Saidi joins increasing evidence of early complex social behaviours in Homo sapiens.

Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. In a new study in ACS' Nano Letters, researchers describe a high-tech alternative: a reversible textile they designed to trap warmth in the cold and reflect it during hot weather, all while generating small amounts of electricity.

Reflexes protect our bodies - for example when we pull our hand back from a hot stove. These protective mechanisms could also be useful for robots. In this interview, Prof. Sami Haddadin and Johannes Kühn of the Munich School of Robotics and Machine Intelligence (MSRM) of the Technical University of Munich (TUM) explain why giving test subjects a "slap on the hand" could lay the foundations for the robots of the future.

Marine scientists are calling on the EU to adopt a comprehensive plan to protect dolphins and porpoises from fisheries bycatch in European waters. To help address the bycatch issue, which is the primary global threat to dolphins and porpoises, the researchers put forward a framework to reduce bycatch levels.

Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers reporting in ACS Applied Materials & Interfaces have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

There is currently no consensus on what quality end-of-life care for children with cancer looks like, or how to measure and deliver it; however, investigators recently assembled an expert panel to help fill this void. In a study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the panel endorsed 16 measures that cover different aspects of care that are important for children with cancer and their families.

A recent study from the University of Helsinki monitors the breakthrough progresses in the development of microneedles for immunotherapy and discusses the challenges regarding their production. Researchers suggest using microneedles for immunotherapy due to the high abundance of immune cells under the skin. The aim is to vaccinate or treat different diseases, such as cancer and autoimmune disorders, with minimal invasiveness and side effects.

Researchers at the Medical University of South Carolina (MUSC) report in Neuropsychopharmacology that a mutation in the gene EPHB2 is linked to increased autism risk in girls.

Biophotonics in Photomedicinehttps://doi.org/10.15212/bioi-2020-0043Announcing a new article publication for BIO Integration journal. In this editorial the authors Hui Liu and Juan Chen from Shanxi Eye Hospital, Taiyuan, China discuss biophotonics in photomedicine.

In this latest press release from the Imperial Brands Science website, we detail how our researchers developed an advanced 3D lung tissue model, leading to the first peer-reviewed vaping study evaluating repeated cigarette smoke and aerosol exposure. Results showed minimal effects to lung tissue from vape aerosol compared to cigarette smoke.

A series of distributional lists is being published for a group of organisms that, despite its size and diversity, is still poorly known: the insect order Hymenoptera, which includes ants, bees and wasps. The surveyed area spreads across Canada, Alaska and Greenland. When complete, this will be the largest species checklist for northern North America. The checklists are being published as a topical collection of eleven papers in the open-access, peer-reviewed Journal of Hymenoptera Research.

The examination of an Estonian girl with progressive muscle weakness brought about collaboration of researchers from ten countries, which led to the discovery of a new form of muscular dystrophy caused by changes in the Jagged2 (JAG2) gene. In the research, a special muscle magnetic resonance imaging study was used in Estonia for the first time, revealing a pattern of muscle involvement characteristic of pathogenic variants in JAG2.
