Millions of Americans have inflammatory bowel disease (IBD), which occurs in one of two forms: Crohn’s disease or ulcerative colitis. Though the two have similar symptoms, they require different treatment strategies, and tests to distinguish between them are invasive. Reporting in ACS’ Journal of Proteome Research, researchers now show that…
Guangzhou Institutes of Biomedicine and Health researchers have successfully created chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing humanized kidneys had normal structure and tubule formation after 28 days. This is the first time that scientists have been able to…
Between 1840 and 1867, thousands of enslaved Africans who had been “liberated” from slave ships intercepted by the British Royal Navy were taken to the South Atlantic island of St Helena. But little is written in history books or otherwise known about the lives of these individuals. Now, ancient DNA…
In many animals, including ants, the blood-brain barrier (BBB) ensures normal brain function by controlling the movement of various substances in and out of the brain. Now, researchers reporting in the journal Cell on September 7 have made the unexpected discovery that the BBB in carpenter ants plays an active…
While public discussions often focus on climate change driving people to emigrate, new research published in Nature Human Behaviour shows that net-migration patterns around the world are actually more strongly linked with socio-economic factors. The study also provides a new, high-resolution dataset of net-migration over the past two decades to…
Alzheimer’s disease is the most common cause of dementia that affects more than 6.5 million Americans, according to the Alzheimer’s Association. To find effective treatments and slow the progression of this debilitating disease, researchers have made much progress in developing new drugs that target beta-amyloid plaques, one of the hallmarks…
A star like our own Sun in a nearby galaxy is gradually being eaten away by a small but ravenous black hole, losing the equivalent mass of three Earths every time it passes close. The discovery by University of Leicester astronomers is reported today (7 September) in Nature Astronomy and…
RNA vaccines against Covid-19 have proven effective at reducing the severity of disease. However, a team of researchers at MIT is working on making them even better. By tweaking the design of the vaccines, the researchers showed that they could generate Covid-19 RNA vaccines that produce a stronger immune response,…
Patescibacteria are a group of puzzling, tiny microbes whose manner of staying alive has been difficult to fathom. Scientists can cultivate only a few types, yet these bacteria are a diverse group found in many environments. The few types of Patescibacteria that researchers can grow in the lab reside on…
A vital component of the batteries at the heart of electric vehicles and grid energy storage, lithium is key to a clean energy future. But producing the silvery-white metal comes with significant environmental costs. Among them is the vast amount of land and time needed to extract lithium from briny…
Groundbreaking research published today in Nature Genetics describes the largest-ever study into the genetics of random “round-the-clock” blood glucose levels. The study, involving almost half a million people of diverse backgrounds, describes new DNA variants influencing blood sugar levels measured “at random.” The team of researchers, led by Professor Inga…
Oregon State University research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice. Published today in Nature Geoscience, the study shows that glacier ice, characterized by pockets of pressurized air, melts…
In many neurodegenerative disorders, abnormal proteins progressively aggregate and propagate in the brain. But what comes first, aggregation or propagation? Researchers from Japan share some new insights about the mechanism involved in Parkinson’s disease. In a study published recently in Cell Reports, researchers from Tokyo Medical and Dental University (TMDU)…
When dairy cows are fed diets with reduced protein concentrations — aimed at decreased environmental nitrogen pollution from their manure such as nitrate leaching, nutrient-laden run-off and ammonia volatilization — their milk production can suffer. Supplementing the amino acid histidine may help in maintaining, and even increasing, milk and milk-protein…
From the Middle Ages to the Enlightenment, “monstrous births” — malformed or anomalous fetuses — were, to Western medicine, an object of superstition. In 19th-century America, they became instead an object of the “modern scientific study of monstrosity,” a field formalized by French scientist Isidore Geoffroy Saint-Hilaire. This clinical turn…
Brezna, Montenegro Reuters — Seven competitors lying down on mats are vying for the coveted title of “Laziest Citizen” after smashing the previous record in a satirical contest held annually in a holiday resort in northern Montenegro. A lying down record of 117 hours was set at last year’s contest…
One of the most unique of all sea turtle species, the leatherback (Dermochelys coriacea), is distinguished by its smooth, “leathery” looking carapace or shell. Listed as vulnerable, this species is experiencing population declines from natural and anthropogenic threats — including climate change. Environmental conditions affect sea turtles’ reproductive success inside…
New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the nature of dark matter. Mysterious dark matter accounts for most of the matter in the Universe. Dark matter is invisible…
