Smelling a familiar scent can help depressed individuals recall specific autobiographical memories and potentially assist in their recovery, discovered a team of University of Pittsburgh School of Medicine researchers and UPMC social workers in a study published today in JAMA Network Open. The study showed that scents are more effective than words at cueing up a memory of a specific event and could even be used in the clinical setting to help depressed individuals get out of the negative thought cycles and rewire thought patterns, ...

A cohort study of older adults found that those who followed recommended exercise guidelines before the pandemic had significantly lower odds of being infected or hospitalized from COVID-19 than those who did not follow guidelines Need another reason to keep up with your exercise routine? Staying active just might protect you from infection and hospitalization from COVID-19. A new study led by investigators from Brigham and Women’s Hospital, a founding member of Mass General Brigham, suggests that higher levels of physical activity before the pandemic began in 2020 were associated with a lower likelihood of contracting ...

Type 2 diabetes alters the behavior of discs in the vertebral column, making them stiffer, and also causes the discs to change shape earlier than normal. As a result, the disc’s ability to withstand pressure is compromised. This is one of the findings of a new study in rodents from a team of engineers and physicians from the University of California San Diego, UC Davis, UCSF and the University of Utah.  Low back pain is a major cause of disability, often associated with intervertebral disc degeneration. People with Type 2 diabetes face ...

In nature, the collective motion of some birds and fish, such as flocks of starlings and shoals of sardines, respectively, can generate impressive dynamic phenomena. Their study constitutes active matter science, which has been a topic of great interest for the past three decades. The unique collective dynamics of active matter are governed by the motion of each individual entity, the interactions among them, as well as their interaction with the environment. Recent studies show that some self-propelling molecules and bacteria show circular motion with a fixed chirality (the property of an object where it cannot be superimposed upon its mirror image through any number of rotations ...

Lost fishing lines and ropes are a growing problem. As a leading fishing nation, Norway, with its long coastline and fish-rich waters, is particularly vulnerable to marine litter. A new study from the Norwegian University of Science and Technology (NTNU) shows that only a third of all ropes produced and sold in Norway can be recycled in a sustainable way. The rest are burned, buried, sent out of the country - or just pile up and contribute to something called ghost fishing. That's when lost or abandoned fishing gear, floating in the ocean or anchored to the bottom, inadvertently continues to catch marine creatures long ...

UNDER EMBARGO UNTIL 8AM EST ON FEB. 13, 2024 ITHACA, N.Y. – Cornell University researchers have created a new version of a microbe to compete economically with E. coli – a bacteria commonly used as a research tool due to its ability to synthesize proteins – to conduct low-cost and scalable synthetic biological experiments. As an inexpensive multiplier – much like having a photocopier in a test tube – the bacteria Vibrio natriegens could help labs test protein variants for creation of pharmaceuticals, synthetic fuels and sustainable compounds that battle weeds or pests. The microbe can work effectively without costly incubators, shakers or deep freezers ...

COLUMBUS, Ohio – A new study examines the circumstances behind who is found at fault when cars hit pedestrians in an urban area.   Results showed that the environment where the crash took place – especially the types of roads and the amount of access to marked crosswalks – played a key role in whether the pedestrian or the driver was blamed for the collision.   In the study, done in Columbus, pedestrians were more likely to be blamed when they were crossing roads with a high volume of cars traveling at faster speeds, and where crosswalks were few and far between.   In areas of the city – such as downtown – ...

Oxytocin (OXT) is a hormone that is known for its effects on psychological well-being and emotional bonding in animals. Interestingly, research has shown that this natural chemical in the brain plays a crucial role in other cognitive processes as well, including learning and memory. Now, scientists may have discovered exactly how OXT influences memory in animals by studying “OXT neurons” that contain OXT receptors and function differently based on the availability of the chemical in the brain. In a recent study published on 16 November 2023, in PLOS One, a group ...

In supramolecular chemistry, the self-assembly state of molecules plays a significant role in determining their tangible properties. Controlling the self-assembled state has garnered significant attention as it can be exploited to design materials with desired properties like charge transport capability and fluorescence wavelength. For years, scientists have been trying to decipher how molecular organization impacts the properties of supramolecular assemblies that are in the nano (<10 nm) and mesoscopic (10–1000 nm) scales. However, the study of structures with supramolecular polymer assemblies derived from the same monomer is often hindered by dynamic structural ...

Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions – as shown in a study just released by Dr. Armineh Barkhordarian from Universität Hamburg’s Cluster of Excellence for climate research CLICCS.

A new study, co-led by UCLA Health and the University of Glasgow, found that young teenagers who develop a strong distrust of other people as a result of childhood bullying are substantially more likely to have significant mental health problems as they enter adulthood compared to those who do not develop interpersonal trust issues. The study, published in the journal Nature Mental Health on Feb. 13, is believed to be the first to examine the link between peer bullying, interpersonal distrust, and the subsequent development of mental health problems, such as anxiety, depression, hyperactivity and anger. Researchers ...

On healthy reefs around the world, corals, algae, fishes and microbes live interconnected and in balance—exchanging nutrients, resources, and chemical signals. New research led by the University of Hawai‘i (UH) at Mānoa and and the Royal Netherlands Institute for Sea Research (NIOZ) revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.  “Our results demonstrate how the impacts of both short-term thermal ...

Short and simple comments from ordinary social media users can help others online to spot fake news, a new study shows.   Research shows reading corrections from others online can reduce the perceived accuracy of and engagement with incorrect content.   Experts found the format and strength of corrective comments do not matter much. Social media users do not need to write long and detailed comments to flag false content.   While the study shows the general effectiveness of social correction, it also finds ...

HOUSTON ― A specific combination of targeted therapy and immunotherapy may better help patients with non-small cell lung cancer (NSCLC) overcome inherent immune resistance and reinvigorate anti-tumor activity, according to a new study led by a researcher from The University of Texas MD Anderson Cancer Center.   Results from the Phase II umbrella HUDSON study, published today in Nature Medicine, demonstrated that the anti PD-L1 antibody, durvalumab, coupled with the ATR inhibitor, ceralasertib, provided the greatest clinical benefit of four combinations evaluated.   This pair had an objective response ...

A diet that limits meat and dairy but is rich in fruits, vegetables, grains, and nuts is linked to less erectile dysfunction, urinary incontinence, and other common side effects seen in prostate cancer patients, a new study shows. Led by researchers at NYU Grossman School of Medicine and Harvard T.H. Chan School of Public Health, the analysis of more than 3,500 men with prostate cancer explored whether eating a more plant-based diet was associated with quality-of-life issues that often arise after treatment. Sorting patients into five groups (quintiles) based on the proportion of plant versus animal foods the men said they eat, the authors found ...
