For the first time, researchers have pinpointed a date when elite Mongol Empire people were drinking yak milk, according to a new study.
For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.
Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.
Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e.,...
Scientists say their study could shed light on stress-related mental illnesses but that more research is needed.
In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a team has discovered a new physical mechanism explaining naturally occurring X-rays associated...
New research reveals that mutations in the stem of the SARS-CoV-2 spike protein led to the virus becoming progressively tighter over time, which may have improved the virus's ability to transmit through nasal droplets and infect host cells once in the body.
Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the...
There are approximately 30 trillion cells in a human body and our health is predicated on them properly interacting with and supporting each other, with the immune system playing a particularly pivotal role. One of the defining characteristics of aging is a decline in the proper functioning of our immune system. Centenarians, a rare population of individuals who reach 100 years or more, experience...
End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by an environmental physicist. To investigate the carbon fluxes over Australia, the researchers studied atmospheric CO2 measurements. Their analyses show that CO2 emissions spike when heavy rain falls on dried-out soil, thus activating microorganisms...
A new type of nanoparticle can be administered to the lungs, where it can deliver messenger RNA encoding useful proteins. Researchers hope to use them to develop new treatments for cystic fibrosis and other lung diseases.
Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.
Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.
Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
European forests are increasingly turning brown in the course of hot, dry summers. In the scorching summer of 2022, Europe experienced more trees turning brown than ever, with 37% of temperate and Mediterranean forest regions affected. In the three-year meteorological history of low-?greenness events, characteristic weather signals can be found as precursors of the events.
Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Harsh discipline from parents puts young children at greater risk of developing lasting mental health problems, new research shows. A study with over 7,500 children in Ireland found those exposed to 'hostile' parenting at age three were 1.5 times likelier to have 'high risk' mental health symptoms at age nine. Hostile parenting involves frequent harsh treatment: for example, shouting at children...
