A discovery from researchers at the University of Illinois Chicago may lead to new treatments for individuals who suffer from alcohol use disorder and depression. The study, “Transcriptomics identifies STAT3 as a key regulator of hippocampal gene expression and anhedonia during withdrawal from chronic alcohol exposure,” is published in the journal Translational Psychiatry by researchers at UIC’s Center for Alcohol Research in Epigenetics.
A plant-based diet appears to afford significant protection to rats bred to become hypertensive on a high-salt diet, scientists report. When the rats become pregnant, the whole grain diet also protects the mothers and their offspring from deadly preeclampsia.
SLAC and Stanford scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. The results could suggest a fix.
The observation of a previously undetected biological mechanism for closing gaps in living tissue improves basic understanding of the wound-healing process and may one day inform strategies to speed healing after surgery and could hold other medical benefits, according to a team of Penn State and Singapore researchers.
The American Society of Anesthesiologists (ASA) asked United States District Judge Madeline Cox Arleo on June 11 to see the “trade libel” suit filed by Pacira BioSciences two months ago for what it is: an egregious and unjustified public relations campaign that seeks to chill scientific research and debate about Pacira’s controversial drug EXPAREL (liposomal bupivacaine). In its case, Pacira disputes the conclusions of peer-reviewed articles and an editorial in the February 2021 issue of Anesthesiology that EXPAREL lacks a comparative benefit over standard bupivacaine, even though it costs 100 times as much.
DALLAS – June 14, 2021 – Overweight cancer patients receiving immunotherapy treatments live more than twice as long as lighter patients, but only when dosing is weight-based, according to a study by cancer researchers at UT Southwestern Medical Center.
While best known as the code for genetic information, DNA is also a nutrient for specialised microbes. An international team of researchers led by Kenneth Wasmund and Alexander Loy from the University of Vienna has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source.
In research published today in Nature Communications, engineers from Rensselaer Polytechnic Institute demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices’ properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward developing quantum emitters needed for future quantum simulation and computing.
People with health insurance are receiving the COVID-19 vaccine at a higher rate than those without insurance, despite the vaccine being free, according to a national survey from the Edward J. Bloustein School of Planning and Public Policy at Rutgers University-New Brunswick.
Summer picnics and barbecues are only a few weeks away! As excited as you are to indulge this summer, Escherichia coli bacteria are eager to feast on the all-you-can-eat buffet they are about to experience in your gut. However, something unexpected will occur as E. coli cells end their journey through your digestive tract. Without warning, they will find themselves swimming in your toilet bowl, clinging to the last bits of nutrients attached to their bodies.
Public health measures designed to reduce the spread of the COVID-19 virus may have fostered a substantial side benefit: A 53 percent drop in hospital admissions for chronic obstructive pulmonary disease (COPD), likely due to a drop in circulating seasonal respiratory viruses such as influenza.
Acoustics researchers at Aalto University, in collaboration with professional monitoring loudspeaker manufacturer Genelec, have investigated just how small of a variation in sound delay the human ear can detect in the most sensitive frequency range for hearing. People normally hear sound in the range of 20 and 20,000 hertz.
Carbon footprint declarations are used in construction to ease product selection for low carbon building, but these standards don’t yet exist for green elements like soil, bushes and plants. A new study led by Aalto University is the first to map out how green infrastructure can be a resource for cities on the path to carbon neutrality.

More physical activity programming could mitigate the effects of stress and improve worker mental and emotional health.
Can people learn to better identify fake news about COVID-19—and if so, would they be less likely to share that fake story with others? Perhaps, but it may take more than simply priming them to think more critically beforehand.
Faculty from the McKelvey School of Engineering and the School of Medicine teamed up to design better grafts for dialysis patients.

A study led by University of Minnesota Twin Cities researchers uncovered a property of magnetic materials that will allow engineers to develop more efficient spintronic devices in the future. Spintronics focuses on using the magnetic “spin” property of electrons instead of their charge, which improves the speed and efficiency of devices used for computing and data storage.

Researchers from NUS have come up with a way to use one single device – such as a mobile phone or smart watch – to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables.
Study shows that scent-enhanced virtual reality technologies, or OVR, can be a safe and effective integrative approach to target anxiety, stress, and pain when combined with standard inpatient psychiatric care.
A new study released today finds residents in several states with the highest obesity rates in the country are among the least likely to undergo weight-loss surgery, long considered the standard of care for severe obesity and related diseases including type 2 diabetes and heart disease.
Weight-loss surgery improves or resolves diseases including type 2 diabetes, heart disease and high blood pressure and can lead to significant and durable weight loss for many people, but the operation has largely been restricted to those with severe obesity, which means about 75 to 100 pounds overweight or a body mass index (BMI) of 35 or higher with an obesity-related disease.
The prevalence of genetic mutations associated with breast cancer in Black and white women is the same.

The Uttarakhand region of India experienced a humanitarian tragedy on Feb. 7, 2021, when a wall of debris and water barreled down the Ronti Gad, Rishiganga and Dhauliganga river valleys. This debris flow destroyed two hydropower facilities and left more than 200 people dead or missing. A self-organized coalition of 53 scientists, including researchers from the University of Washington, came together in the days following the disaster to investigate the cause, scope and impacts.
New paper explores links among the diet, gut microbiota and health status.
With the increase in demand for flexible wearable electronics, researchers have explored flexible energy storage devices, such as flexible supercapacitators, that are lightweight and safe and easily integrate with other devices. Printing electronics has proved to be an economical, simple, and scalable strategy for fabricating FSCs. In Applied Physics Reviews, researchers provide a review of printed FSCs in terms of ability to formulate functional inks, design printable electrodes, and integrate functions with other electronic devices.
Evidence suggests auditory and vestibular effects should be added to the growing list of physiological impacts of COVID-19. During the 180th Meeting, Colleen Le Prell from the University of Texas at Dallas will talk about hearing and balance disorders associated with coronavirus infection and how pandemic-related stress and anxiety may aggravate tinnitus symptoms. Her presentation, “Hearing disorders secondary to infection with SARS-CoV-2,” will take place Thursday, June 10.
Researchers from Tel Aviv University took part in a new international study proposing an amendment to the widely accepted theory on the extinction of animal species – by moving the focus from the animal’s body size to its reproductive capacity.
