A limited menu of prey may weave a tangled food web by emboldening wolf spiders of multiple species to dine on each other and even cannibalize their own, says a study from the University of Nebraska–Lincoln. Ecologists have long known that predators with otherwise-similar diets can coexist by effectively divvying up the food sources of a community to ease competition and, ideally, leave enough prey for everyone. But analyses of wolf spider species in Nebraska suggest that when the diversity of their mutual prey is lacking, the eight-legged ...

Researchers at the UCLA David Geffen School of Medicine, the Howard Hughes Medical Institute at UCLA and the National Institutes of Health have developed a zebrafish model that provides new insight into how the brain acquires essential omega-3 fatty acids, including docosahexaenoic acid (DHA) and linolenic acid (ALA). Their findings, published in Nature Communications, have the potential to improve understanding of lipid transport across the blood-brain barrier and of disruptions in this process that can lead to birth defects or neurological conditions. The model may also enable researchers to design drug molecules that are capable of directly ...

FINDINGS Due to a policy decision in 2010 by the U.S. Food and Drug Administration (FDA), the price of a prescription for the therapeutic gout drug colchicine increased nearly 16-fold from $11.25 in 2009 to $190.49 in 2011. Out-of-pocket costs for patients who took the drug jumped more than four-fold from $7.37 to $39.49 over the same period. Use of colchicine dropped 17% during this time and 27% over the following decade. Patients turned to alternative medications for gout such as allopurinol and corticosteroids. However, disease ...

CAMBRIDGE, MA -- Much of the human genome is made of regulatory regions that control which genes are expressed at a given time within a cell. Those regulatory elements can be located near a target gene or up to 2 million base pairs away from the target. To enable those interactions, the genome loops itself in a 3D structure that brings distant regions close together. Using a new technique, MIT researchers have shown that they can map these interactions with 100 times higher resolution than has previously been possible. “Using this method, we generate the highest-resolution maps of the 3D genome that have ever been generated, and what we see are a lot of interactions between ...

Going beyond pregnancy and COVID-19, the world could someday soon come to rely on at-home tests for many diseases thanks in part to AI-fueled improvements. University of Florida scientists have used artificial intelligence tools to simplify a test that works for both hepatitis C and SARS-CoV-2, the virus that causes COVID-19. The simplified test happens in one small test tube in just a few minutes. With further refinement, it could come to doctor’s offices soon and, one day, even home tests that are as easy as a pregnancy test. “We are trying to build a home-based test that is as reliable as a lab-based test,” said Piyush ...

New York, NY—May 8, 2023—Researchers at Columbia Engineering have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that can convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record. Because the devices are so thin, transparent, and compatible with photonic integrated circuits ...

What cell types are found in which human tissue, and where? Which genes are active in the individual cells, and which proteins are found there? Answers to these questions and more are to be provided by a specialised atlas – in particular how the different tissues form during embryonic development and what causes diseases. In creating this atlas, researchers aim to map not only tissue directly isolated from humans, but also structures called organoids. These are three-dimensional clumps of tissue that are cultivated in the laboratory and develop in a way similar ...

Globally, air pollution is a major public health hazard. A key air pollutant linked to health risks is ambient fine particulate matter (PM2.5), which consists of minute particles, sized less than or equal to 2.5 μm, suspended in the air. According to the WHO, annual PM2.5 levels should not exceed 5 μg/m3. However, the current PM2.5 levels in China far exceed this standard and are responsible for approximately 1.4 million PM2.5-related excess deaths annually. Even as the country steadily works towards reducing ...

(Boston)—The quality of surgery can drastically influence both short- and long-term postoperative outcomes and is a crucial consideration in studies that assess surgical outcomes. One approach for developing accurate quality measures is benchmarking, a quality-improvement process in which the best possible outcomes are identified to serve as a point of reference against which performance can be compared. Surgery for gallbladder cancer (GBC) is a technically challenging surgical procedure and requires considerable expertise ...
