Recent experiments by psychologists at Temple University and the University of Pittsburgh shed new light on how we learn and how we remember our real-world experiences. The research, described in the March 12 online edition of Proceedings of the National Academy of Sciences (PNAS), suggests that varying what we study and spacing out our learning over time can both be helpful for memory — it just depends on what we’re trying to remember. “Lots of prior research has shown that learning and ...

Encompassing over 16 000 km2 of towering mountains, long fiords, lush valleys, and massive ice caps, Agguttinni Territorial Park is a protected area on northern Baffin Island, Nunavut, Canada. This park, and all of Nunavut, is Inuit Nunangat – Inuit homeland in Canada – and the park protects sites and biodiversity stewarded by Inuit since time immemorial. Agguttinni means “where the prevailing wind occurs” in the Inuktitut local dialect. The park includes important bird areas, key habitats for polar bears and caribou, and numerous important Inuit cultural sites. It is very remote: no roads lead to it, and access ...

The chikungunya virus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes and responsible for more than 900 deaths in Brazil since it arrived around ten years ago, is capable of spreading through the blood, reaching multiple organs and crossing the blood-brain barrier, which protects the central nervous system. The mechanisms of action observed for the first time in fatal cases by a group of Brazilian, American and British researchers were reported in an article published on March 12 in the journal Cell Host & Microbe. The findings reinforce the need ...

Are surgeons giving patients unrealistic expectations about recovery after robotic lung surgery? That’s what CU Department of Surgery faculty member Robert Meguid, M.D., MPH, and surgery resident Adam Dyas, M.D., set out to discover after realizing the guidance they were offering patients might be based on outdated or anecdotal information. “Traditionally, in surgery, we're taught to tell patients that they'll be back to normal from surgery within six weeks,” says Meguid, professor of cardiothoracic ...

The collapse of the former Soviet Union in 1991 had social, political and economic effects worldwide. Among them was a suspected role in slowing human-generated methane emissions. Methane had been rising steadily in the atmosphere until about 1990. Atmospheric scientists theorized that economic collapse in the former USSR led to less oil and gas production, and thus a slowdown in the rise of global methane levels, which has since resumed. But new University of Washington research uses early satellite records to dispute that assumption. The study, published March 12 in the ...

A team of researchers at Oak Ridge National Laboratory demonstrated that a light-duty passenger electric vehicle can be wirelessly charged at 100-kW with 96% efficiency using polyphase electromagnetic coupling coils with rotating magnetic fields.

CORVALLIS, Ore. – Gun manufacturers are appealing to women as “serious students” of firearms in their advertising – a shift in strategy over the last two decades that may be contributing to increased gun sales, a new study shows. From 2007 through 2022, women’s gun ownership rose from 16% to 22%, while the rate for men stayed roughly steady at 43%. And more than half of new gun owners in the United States between 2019 and 2021 were women. “Those trends in gun ownership ...

Adults 65 and older, who were hospitalized for a variety of medical conditions, had highly satisfying conversations about whether they wanted CPR, regardless of whether doctors used the terms “allow a natural death” or “do not resuscitate” for indicating no CPR, according to a pilot study by Rutgers Health researchers. The study, published in the Journal of the American Geriatrics Society, sought to determine the best language doctors could use when discussing a patient’s code ...

CAMBRIDGE, MA -- More than 20 million Americans undergo colonoscopy screenings every year, and in many of those cases, doctors end up removing polyps that are 2 cm or larger and require additional care. This procedure has greatly reduced the overall incidence of colon cancer, but not without complications, as patients may experience gastrointestinal bleeding both during and after the procedure. In hopes of preventing those complications from occurring, researchers at MIT have developed a new gel, GastroShield, that can be sprayed onto the surgical sites through an endoscope. This gel forms a tough but flexible protective layer that ...

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years they have attained notoriety for a completely different reason: it has been suggested that instead of one giraffe species, there might be no fewer than four different species. Such dramatic taxonomic reappraisals in highly conspicuous and well-known “flagship” taxa are very unusual. The suggestion caused some uproar in the scientific community and received a lot of media attention. Much is at stake, because the way that most nature conservation works is focused on species, meaning that each species must receive its own dedicated conservation action plan and must ...

Epigenetic processes allow different cell types to emerge from a single genome. Throughout development, cells differentiate and acquire distinct characteristics by expressing the same genome in different ways. However, a less-known aspect of this process is how cells maintain their unique identities over time. A study led by the Transcriptional and Epigenetic Mechanisms of Neuronal Plasticity laboratory, headed by Angel Barco at the Institute for Neurosciences, a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University (UMH) of Elche, has determined that the protein Kdm1a plays ...
