Marine Protected Areas (MPAs) are having a positive spillover effect, producing more “trophy-size” fish just outside of the fully protected areas, and the effect is growing stronger over time. That’s according to research led by University of Hawaiʻi at Mānoa scientists at the Hawaiʻi Institute of Marine Biology (HIMB) published today in Science Advances. The research provides the first global assessment of the benefits of MPAs. “Trophy-size” refers to fish that are exceptionally long or heavy and are considered a rare, ...

CHAMPAIGN, Ill. — Understanding how soft materials fail under stress is critical for solving engineering challenges as disparate as pharmaceutical technology and landslide prevention. A new study linking a spectrum of soft material behaviors — previously thought to be unrelated — led researchers to identify a new parameter they call the brittility factor, which allows them to simplify soft material failure behavior. This will ultimately help engineers design better materials that meet future challenges. University of Illinois Urbana-Champaign chemical and biomolecular engineering professor Simon Rogers and graduate student Krutarth Kamani specialize ...

DURHAM, N.C. – The world around us is constantly being flash photographed by adaptive radar systems. From salt flats to mountains and everything in between, adaptive radar is used to detect, locate and track moving objects. Just because human eyes can’t see these ultra-high frequency (UHF) ranges doesn’t mean they’re not taking pictures. Although adaptive radar systems have been around since World War II, they’ve hit a fundamental performance wall in the past couple of decades. But with the help of modern AI approaches and lessons learned from computer vision, researchers at Duke University have broken through that wall, and they want to bring everyone ...

LAWRENCE — Around the globe, communities at risk from repeated flooding due to climate change face stark decisions. Some communities in peril of flooding may resolve, or be urged, to relocate to a safer location — something known as “managed retreat.” In the United States, flood-prone communities in coastal states like Louisiana and Alaska already have commenced managed retreat inland.  “It's retreating from risk, and we hope to provide decision support for the equitable implementation ...

HUNTINGTON, W.Va. – Marshall University was awarded a $3.3 million grant (#R01DA057931) from the National Institute on Drug Abuse (NIDA) to examine the genetic mechanisms that underlie fentanyl addiction.   In 2022, fentanyl overdose was the leading cause of death for U.S. adults aged 18 to 45, according to Families Against Fentanyl (2023).   “This alarming statistic highlights the urgent need to understand why some people are more susceptible to fentanyl addiction,” ...

By Leah Shaffer Amyloid-beta (A-beta) aggregates are tangles of proteins most notably associated with neurodegenerative diseases like Alzheimer’s. Despite its constant stint in the limelight, however, researchers have been unable to get a good understanding of how A-beta comes together and breaks apart. “The way A-beta behaves in a variety of environments, including the human brain, is elusive,” said Brian Sun, an electrical systems and engineering alumnus of Washington University in St. Louis who is now an MD/PhD student in the School of Medicine. “There’s an understanding of growth and decay that isn’t ...

New evidence of human occupation in southeast Indonesia dating back 42,000 years offers fresh clues on the route taken by some of the first humans to arrive in our region, according to a study from The Australian National University (ANU).  Lead author and ANU PhD candidate Hendri Kaharudin said the location of the discovery -- at Elivavan on Indonesia’s Tanimbar islands -- makes it especially significant.   “Tanimbar is located just off the ‘Sahul shelf’, which encompasses modern-day Australia, as well as New Guinea,” he said.  “The question ...

The human body hosts a diverse array of microorganisms that maintain a delicate balance crucial for overall health. This microbial harmony can be disrupted by factors like infections, aging, and hormonal changes, leading to dysbiosis—a condition where microbial communities become imbalanced and harmful to health. Postmenopausal women, for instance, are particularly susceptible to recurrent urinary tract infections and inflammation, including cystitis, due to these microbial shifts. Dr. Takanori Sekito from the Department of Urology, Okayama University Graduate School of Medicine, Japan explains, “In postmenopausal women, the vaginal flora changes ...

COLUMBUS, Ohio – Chemists have been working to synthesize high-value materials from waste molecules for years. Now, an international collaboration of scientists is exploring ways to use electricity to streamline the process. In their study, recently published in Nature Catalysis, researchers demonstrated that carbon dioxide, a greenhouse gas, can be converted into a type of liquid fuel called methanol in a highly efficient manner.  This process happened by taking cobalt phthalocyanine (CoPc) molecules and spreading them evenly on carbon nanotubes, graphene-like tubes that have unique electrical properties. On their surface was an electrolyte ...

When it comes to helping patients with high blood pressure get their hypertension under control, a new Tulane University study finds that pharmacists and community health workers have the best success rates. The study, published in Circulation: Cardiovascular Quality and Outcomes, analyzed data from 100 hypertension trials around the world and compared blood pressure reductions by the type of healthcare professionals who led the interventions. While interventions led by nurses, physicians and multiple healthcare professionals still significantly reduced blood pressure for patients, pharmacists achieved the greatest improvements, followed ...

Direct air capture was identified as one of the ‘Seven chemical separations to change the world’. This is because although carbon dioxide is the main contributor to climate change (we release ~40 billion tons into the atmosphere every year), separating carbon dioxide from air is very challenging due to its dilute concentration (~0.04%). Prof Ian Metcalfe, Royal Academy of Engineering Chair in Emerging Technologies in the School of Engineering, Newcastle University, UK, and lead investigator states, “Dilute ...

New research led by Oregon Health & Science University reveals a promising approach to developing a universal influenza vaccine — a so-called “one and done” vaccine that confers lifetime immunity against an evolving virus. The study, published today in the journal Nature Communications, tested an OHSU-developed vaccine platform against the virus considered most likely to trigger the next pandemic. Researchers reported the vaccine generated a robust immune response in nonhuman primates that were exposed ...

Okinawa’s mangrove forests are home to many animal species, from crabs to kingfishers; they host a diverse ecosystem teeming with life. Among the quirkier residents living there is “Minami-Tobihaze” — the barred mudskipper. “They are fish, but they can walk and live partly on land,” says Dr. Fabienne Ziadi-Künzli from the Nonlinear and Non-equilibrium Physics Unit, who is the first author of a study on mudskipper anatomy, which was recently published in the Journal of Anatomy. Adapting to a new life   The barred mudskipper, scientifically called Periophthalmus argentilineatus, has more than just one oddity. Their eyes ...

The world around us is made up of particles invisible to the naked eye, but physicists continue to gain insights into this mysterious realm. Findings published in Physical Review C by Osaka Metropolitan University researchers show that the nuclear structure of an atom likely changes depending on the distance the protons and neutrons are from the center of the nucleus. OMU graduate student Maito Okada, Associate Professor Wataru Horiuchi, and Professor Naoyuki Itagaki from the Graduate School of Science compared calculations using theoretical models with existing experimental data to determine whether titanium-48, the most common isotope of titanium with 22 protons and 26 neutrons, ...
