If a human comes down with a rash, they might go to the doctor and come away with some ointment to put on it. Indo-Pacific bottlenose dolphins get skin conditions, too, but they come about their medication by queuing up nose-to-tail to rub themselves against corals. In the journal iScience on May 19, researchers show that these corals have medicinal properties, suggesting that the dolphins are usi

She yelled at him and tried to block him from going back into his own house, pulling out a small knife and stabbing the air with it. "Walk down the steps!" he shouted at her as he called 911. "Get off of my fucking ste
Using tens of thousands of stars observed by the Gaia space probe, astronomers from MPIA and Chalmers have revealed the 3D shapes of two large star-forming molecular clouds, the California Cloud and the Orion A Cloud. In conventional 2D images, they appear similarly structured, containing filaments of dust and gas with seemingly comparable densities. In 3D, however, they look quite distinct. In fa
The Sept. 10, 2019 PBS article accompanying the FRONTLINE documentary "Deadly Water" was topped by a provocative headline: "The EPA Says Flint's Water is Safe — Scientists Aren't So Sure." The PBS story relied on a study of adverse health outcomes for people given point-of-use (POU) water filters during the Flint Federal Emergency. We were … Continue reading

Nature Communications, Published online: 19 May 2022; doi:10.1038/s41467-022-30325-4 Multiple pluripotent states have been described in mouse and human stem cells. Here the authors describe trajectories during BMP4 induced primed to naïve transition, which bifurcates into naïve and trophoblast-like branches with a PGC-like intermediate at the naïve branch.
Plants—they're just like us, with unique techniques for handling stress. To save one of the most important crops on Earth from extreme climate swings, scientists are mapping out plants' own stress-busting strategies.
In Myanmar, where abortion is illegal unless the mother's life is at risk, some grassroots networks have made it their mission to provide access to reproductive care. In a post-Roe v. Wade world, such networks are poised to become more popular in the U.S., whether government officials like them or not.

This crime became one of the most notorious of its era, shocking the nation on the eve of the passage of
I dag afholdes den første nationale konference om selvskade blandt unge. Her vil et af budskaberne være, at sundhedspersonale og andre voksne kan være med til at stoppe selvskadende unge ved at turde spørge ind til mistrivsel og selvskade. Det siger Lotte Rubæk, der er psykolog og leder af Team for selvskade i Region Hovedstaden.
Drought: the past is no longer prologue Drought management in the United States (and elsewhere) is highly informed by events of the past, employing records extending 60 years or longer in order to plan for and cope with newly emerging meterorological water deficits. Water resource managers and agricultural concerns use recorded droughts as models for negotiating periods of low precipitation in th

New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation.
Many age-related diseases share a common feature: the mitochondria of cells begin to malfunction. While the cause is not known, scientists have discovered a new mechanism of how mitochondria start to go wrong, which opens new doors for researchers to explore how to begin to fix the problem.
Abnormal tumor blood vessels promote cancer progression and treatment resistance. Researchers have developed two approaches to repair tumor blood vessels and they have devised a method to measure the effects of these approaches. Combining the approaches may be an effective strategy for fixing blood vessel abnormalities that make tumors difficult to treat.
Within many societies and cultures around the world, older adults are too often undervalued and underappreciated, according to a new article. This exacerbates many key challenges that older adults may face. It also undermines the many positive aspects of late life that are of value at both an individual and societal level. In the article, 'Investing in Late-Life Brain Capital,' a global team of ex
A research team has combined two emerging imaging technologies to better view a wide range of biomolecules, including proteins, lipids and DNA, at the nanoscale. Their technique brings together expansion microscopy and stimulated Raman scattering microscopy.
Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and ultimately reshaping the landscape according to inherent patterns and fluctuations that emerge over time. Effective? Yes. Efficient? Not
