New research conducted in mice offers insights into what’s going on at the molecular level that could cause people with diabetes to develop Alzheimer’s disease.   The study adds to a growing body of research on the links between Type 2 diabetes and Alzheimer’s disease, which some scientists have called “Type 3 diabetes.” The findings suggest that it should be possible to reduce the risk of Alzheimer’s by keeping diabetes well controlled or avoiding it in the first place, according to researchers.   Narendra Kumar, an associate professor at Texas A&M University in College ...

A new way to classify tuberculosis (TB) that aims to improve focus on the early stages of the disease has been presented by an international team involving researchers at UCL. The new framework, published in The Lancet Respiratory Medicine, seeks to replace the approach of the last half century of defining TB as either active (i.e., causing illness and potentially infectious to others) or latent (being infected with the bacterium that causes TB [M tuberculosis] but feeling well and not infectious to others) – an approach researchers say is limiting progress in eradicating the disease. Of ...

It’s one of life’s most defining moments—that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage for all to come. Known as gastrulation, this crucial process unfolds in the third week of human development. “Gastrulation is the origin of our own individualization, the emergence of our axis,” says Rockefeller’s Ali Brivanlou. “It is the first moment that separates our heads from our behinds.” Observing the molecular underpinnings of this pivotal event would go a long way toward helping scientists prevent miscarriages and developmental ...

CORVALLIS, Ore. – Arachnophobia can make humans flee at the sight of a brown recluse, black widow or even a daddy long legs, but animal predators of spiders know no such fear. That’s why, paleobiologist George Poinar Jr. explains, some spider species have developed the defense of deception. They masquerade as a much less desirable prey – ants – and Poinar’s recent paper in Historical Biology presents an early record of an ant-mimicking spider in fossilized resin. “Ants are particularly good creatures for spiders to pretend to be – many animals ...

In cases of Alzheimer’s disease, it’s common for a spouse to take on the role of caregiver. Research led by the University of California, Davis, suggests that patients can also support their caretakers, and that reciprocated care has mutual benefits. A new paper published in the journal Aging and Mental Health highlights that couples coping with dementia can navigate the challenges with greater resilience and well-being by working together and supporting each other. “We know that dementia is degenerative, there’s no way back, and spousal caregivers typically ...

Of all the carbon stored in ecosystems around the world, about half can be found in soils. Depending on climate, vegetation, and management, soils can be either a carbon source or a sink. Natural climate solutions (NCS) offer a promising opportunity to bring us closer to our net-zero emissions goals by removing carbon dioxide from the atmosphere and storing it in plant biomass and soil. The growth of bioenergy feedstocks has great potential in this regard, because these grasses both build soil carbon and have the potential to be used to produce carbon-neutral biofuels and bioproducts. Over ...

The summer mating season is looking to get a lot easier for the scarlet tanager, one of a number of migratory songbirds that use the forests of northeastern North America to find a mate. In recent decades, the loss and degradation of bird habitats has led to a precipitous decline in bird populations. Now, a $2 million grant awarded to the National Audubon Society’s Bird-Friendly Maple program, in partnership with College of Natural Resources and Environment Associate Professor Ashley Dayer, will look to improve bird habitats by encouraging maple syrup producers to incorporate forest management practices that allow other ...

Living in neighborhoods where residents have lower incomes and limited food access during pregnancy was associated with an increased risk of babies born small for gestational age or with lower birthweight, according to a new study from the NIH Environmental Influences on Child Health Outcomes (ECHO) Program. Previous studies have shown that maternal diet during pregnancy can impact the physical and mental health of a mother. However, less is known about how food insecurity affects health outcomes for newborns. In a new research article, ECHO researchers analyzed data to understand what connections might exist between where a pregnant ...

"Podcast Or Perish" investigates the historical development of the norms of scholarly communication and asks how podcasting might change how we think about scholarly work. Could this be the call to action academia needs? Read ...

PHILADELPHIA— Only a very small percentage of neurons show changes after an epileptic seizure in mice, but these alterations can be permanent and trigger future seizures that can affect the whole brain and lead to impaired cognition, like memory and learning, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The researchers identified an experimental treatment that, if provided within the first 48 hours after the first seizure, can prevent these long-term changes. The findings, which were published recently in The ...

The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of Washington in Seattle and the Freie Universität Berlin shows that individual ice grains ejected from these planetary bodies may contain enough material for instruments headed there in the fall to detect signs of life, if such life exists. “For the first time we have shown that even a tiny fraction of cellular material could be identified by a mass spectrometer onboard a spacecraft,” said lead author Fabian Klenner, a UW postdoctoral researcher in Earth and space sciences. ...

Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed the international scale of horse trading by the elites of late medieval and Tudor England. Using advanced archaeological science techniques, including studying chemical composition, researchers have been able to identify the likely origins of several physically elite horses and the routes they took to reach British shores during the formative years of their life. These animals – akin to modern supercars – were sourced from a variety of locations across ...

Researchers have for the first time discovered evidence of microplastic contamination in archaeological soil samples. The team discovered tiny microplastic particles in deposits located more than seven metres deep, in samples dating back to the first or early second century and excavated in the late 1980s. Preserving archaeology in situ has been the preferred approach to managing historical sites for a generation. However, the research team say the findings could prompt a rethink, with the tiny particles potentially compromising the preserved remains. Microplastics are small plastic particles, ranging from 1μm (one thousandth of a millimetre) ...

Researchers at the University of Toronto and Sinai Health have created a new platform to identify proteins that can be co-opted to control the stability of other proteins — a new but largely unrealized approach to the treatment of disease. The researchers developed a method to interrogate the entire human proteome for ‘effector’ proteins, which can influence the stability of other proteins via induced proximity. The study marks the first time researchers have searched for effector proteins on this scale, and has identified many new effectors that could be used therapeutically. “We found more than 600 new effector proteins in 14,000 ...
