Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.
Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile…
Normally, a person's pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person's pupils also dilate when they are concentrating on tasks. In…
New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to…
Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic fields suitable for use on chips.
Simulated effects of microgravity significantly affect rhythmicity and sleep in humans, a new study finds. Such disturbances could negatively affect the physiology and performance of astronauts in space.
Scientists are developing and validating a patent-pending novel immunotherapy to be used against glioblastoma brain tumors. Glioblastomas are almost always lethal with a median survival time of 14 months. Traditional methods used against…
Primary health care, conditional cash transfers and social pensions have prevented 1.4 million deaths of all ages in Brazil over the past two decades, according to a new study. If expanded, these programs could avert an additional 1.3…
Based on radio telescope data and models of black hole physics, a team has used neural networks to reconstruct a 3D image that shows how explosive flare-ups in the disk of gas around our supermassive black hole might look.
Researchers have uncovered a remarkable metal alloy that won t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy keeps its shape and resists…
Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.
Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
Inspired by what human liver enzymes can do, chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widely used…
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect…
An international collaboration of researchers has achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform.…
The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian,…
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore…
The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a…
Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process of nuclear beta decay. The research…
Researchers have developed a new shoe insole technology that helps reduce the risk of diabetic foot ulcers, a dangerous open sore that can lead to hospitalization and leg, foot or toe amputations.
A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant…
Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for…
Researchers explore a cancer immunotherapy treatment that involves activating the immune cells in the body and reprogramming them to attack and destroy cancer cells. This therapeutic method frequently uses cytokines, small protein…
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the…
When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track…
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the…
