“Here, we report a chronic wound healing model that can be used to decipher the paradoxical role of cellular senescence in acute versus chronic wound healing.” BUFFALO, NY- May 1, 2023 – A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 8, entitled, “A chronic wound model to investigate skin cellular senescence.” Wound healing is an essential physiological process for restoring normal skin structure and ...

Whenever SLAC National Accelerator Laboratory’s linear accelerator is on, packs of around a billion electrons each travel together at nearly the speed of light through metal piping. These electron bunches form the accelerator’s particle beam, which is used to study the atomic behavior of molecules, novel materials and many other subjects. But trying to estimate what a particle beam actually looks like as it travels through an accelerator is difficult, leaving scientists often with only a rough approximation of how a beam will behave during an experiment. Now, researchers at the Department of Energy’s SLAC, the DOE’s Argonne National ...

Internet search trends may immediately capture how society seeks information related to reproductive health care, according to new research from Indiana University researchers. The study, published today in JAMA Health Forum, analyzed internet searches for abortion- and contraception-related terms following the June 24, 2022, ruling by the United States Supreme Court on Dobbs v. Jackson Women’s Health Organization. Researchers found that searches increased much more in states where reproductive health care access was more likely to be immediately restricted following the decision. “It is still fairly early to see what will be the actual changes in reproductive ...

Politicians who are the parents of daughters provide researchers with a “natural experiment” to test how personal circumstances influence legislators’ roll call votes. Research published in 2008, by author Ebonya Washington, showed that members of the U.S. House of Representatives with daughters cast more liberal votes on women’s issues during the period between 1997 and 2005. But another study published in 2019 by researchers Mia Costa et al., covering the period between 2007 and 2017, did not ...

Myeong Lee, Assistant Professor, Information Sciences and Technology, is leading a study to help people with disabilities and their families in Virginia access information about disability services more easily.  The 2022 Information Access Assessment report by the Virginia Board for People with Disabilities (VBPD) revealed that many people with disabilities and their families struggle to find the necessary information about disability services, even when they actively seek help from service agencies. ...

A new study on herpes infections of the eye from University of Illinois Chicago researchers helps shed light on the question of viral reinfections by identifying a key protein involved in viral reinfections that could be targeted by antiviral drugs. The UIC team examined how the heparanase protein, which is present in all our cells, affects reinfection from the herpes simplex virus type 1 in mice. They found that inhibiting heparanase activity can protect the eyes from being reinfected. Mice that had their heparanase protein blocked ...

A new artificial intelligence system called a semantic decoder can translate a person’s brain activity — while listening to a story or silently imagining telling a story — into a continuous stream of text. The system developed by researchers at The University of Texas at Austin might help people who are mentally conscious yet unable to physically speak, such as those debilitated by strokes, to communicate intelligibly again. The study, published in the journal Nature Neuroscience, was led by Jerry Tang, a doctoral student in computer science, and Alex Huth, an assistant professor of neuroscience and computer science at UT Austin. The work relies in part on a transformer ...

In 2010 Prof. Shlomo Havlin and collaborators published an article in the journal Nature proposing that the abrupt electricity failure causing the famous 2003 Italy blackout was a consequence of the inter-dependency of two networks. According to Havlin's theory the dependency between the power network and its communication system led to cascading failures and abrupt collapse. Havlin's seminal work ignited a new field in statistical physics known as “network of networks” or "interdependent networks" and paved the way for understanding and predicting the effects of the ...

An unusually well-preserved "Marine Dwarf World" from 462 million years ago was found at Castle Bank, Wales by a team led by the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS).

Efforts to combat climate change have contributed to the rise of renewable energy production through solar panels, windmills, and other technologies. Because of this, consumers have now become “prosumers,” capable of producing their own electricity. While the prosumers’ use of distributed renewable energy increases the energy sector’s resilience, their decreased reliance on the bulk electricity market has led to new and unintended consequences. It is anticipated that these avenues will push traditional consumers to become prosumers, making it difficult to recover lumpsum infrastructure investments ...

Magnesium diboride (MgB2), a binary compound, behaves as a superconductor – a substance that offers no resistance to electric current flowing through it – at a moderate temperature of around 39 K (-234°C). This temperature can be achieved using relatively inexpensive liquid hydrogen or neon coolants. In addition, MgB2 is inexpensive, lightweight, and non-toxic, and its precursors – magnesium (Mg) and boron (B) – are abundantly available. As a result, it can replace conventional low-temperature ...

At the end of 2022, the federal government eliminated the “X waiver,” a major hurdle to providing addiction treatment, but progress needs to be continued, according to the authors of a new Perspective piece published in the New England Journal of Medicine. The X waiver required a special license and uncompensated training for physicians and other prescribers, creating a regulatory barrier to offering lifesaving buprenorphine treatment for opioid use disorder. Ending the X, the authors write, is necessary but not sufficient to achieve overdose-prevention goals. Sarah Wakeman, MD, Medical Director for Substance Use Disorder at Mass General Brigham, and her co-author ...

CHAMPAIGN, Ill. — The mechanics behind the collapse of soft materials structure have befuddled researchers for decades.

Photonic chips have revolutionized data-heavy technologies. On their own or in concert with traditional electronic circuits, these laser-powered devices send and process information at the speed of light, making them a promising solution for artificial intelligence’s data-hungry applications. In addition to their incomparable speed, photonic circuits use significantly less energy than electronic ones. Electrons move relatively slowly through hardware, colliding with other particles and generating heat, while photons flow without losing energy, ...

INDIANAPOLIS – A new study conducted by researchers from Regenstrief Institute and the universities of South Carolina and Indiana has found that the most commonly prescribed blood pressure medications, taken for at least six months prior to an intensive care unit (ICU) admission, did not protect against developing delirium in the ICU, regardless of patient age, gender, race, co-morbidities or insurance status. Delirium, an acute brain failure, affects approximately seven million hospitalized patients in the U.S. annually and is associated with longer hospital and ICU length of stay, higher likelihood ...
