A team of scientists used an emerging genetic tool that analyzes DNA in water samples to detect whales and dolphins in New York waters.
A new study using serum from human blood samples suggests neutralizing antibody levels produced by two-dose mRNA vaccines against the original and early variants of the SARS-CoV-2 virus wane substantially over time, and offer essentially no protection against the omicron variant.
In Physics of Fluids, researchers focus their expertise and their microscopes on examining the efficacy of particle filtration by woven fabric, which consists of fibers twisted together into yarns. There are, therefore, two lengthscales: the diameters of the fiber and the yarn. Using 3D imagery produced by confocal microscopy to see the air flow channels, the scientists simulate the airflow through these channels and calculate filtration efficiency for particles a micrometer and larger in diameter. The study concludes for particles in this size range, the filtration efficiency is low.
To understand how hearing loss impacts people, researchers study people's ability to recognize speech, and hearing aid algorithms are often used to improve human speech recognition. In The Journal of the Acoustical Society of America, researchers explore a human speech recognition model based on machine learning and deep neural networks. They calculated how many words per sentence a listener understands using automatic speech recognition. The study consisted of eight normal-hearing and 20 hearing-impaired listeners who were exposed to a variety of complex noises that mask the speech.
Compared to older patients being evaluated for total knee arthroplasty (TKA), younger patients – under age 60 – have similar pain, disability, and willingness to undergo surgery, reports a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
New research from the University of Georgia found that fungal infections account for $6.7 billion in health care spending in 2018. And that’s just the cases that were directly responsible for inpatient hospital stays.
Semiconductor experiments reveal a surprising new source of conductivity from oxygen atoms trapped inside the material.
While many people skipped regular health check-ups during the COVID-19 pandemic, new research indicates that people with multiple sclerosis (MS) used online telehealth services more frequently to keep in contact with their health care providers and were highly satisfied with the outcome.
Past research has shown that people drink more frequently and drink higher amounts of alcohol when they have more bars and restaurants in the neighborhoods where they live. But a new study, focusing on parents of young children, suggests it isn’t just where people live that’s important – it also matters where they spend their time.
People suffering from COVID-19 could have several different SARS-CoV-2 variants hidden away from the immune system in different parts of the body, finds new research published in Nature Communications by an international research team. The study’s authors say that this may make complete clearance of the virus from the body of an infected person, by their own antibodies, or by therapeutic antibody treatments, much more difficult.
An analysis of data from 1,480 COVID-19 patients hospitalized in March 2020 at 57 U.S. hospitals is one of the few studies conducted in diverse, multicenter patient populations that describes patients’ illness trajectory, patterns of organ failure, therapies and clinical outcomes.

E-cigarette vapers and hookah smokers are more than twice as likely to exhale particles through their nose compared with cigarette smokers, who favor exhaling the emissions from their mouth, a new study shows. The finding makes it plausible that the former group is at risk for inflammation and cancers of the nose, sinuses, and throat, conditions seen less often in cigarette smokers, according to the study authors.

Researchers at Huntsman Cancer Institute are developing breast cancer models using tumors donated by patients to narrow the number of drugs that might be effective in each tumor based on the unique characteristics and behavior in these models of cancer.
Leonid Peshkin has developed a new model system aiming to illuminate the fundamentals of aging
Each year, pregnant female elephant seals take an approximately 240-day trek over 10,000 kilometers across the Eastern North Pacific Ocean before returning to their breeding beaches to give birth within five days of their arrival. Now, a study appearing February 28 in the journal biology Current Biology finds that this impressive navigation ability depends on an internal map sense, which functions much like a built-in GPS.
A recent study published in Current Eye Research evaluated seven studies looking at the relationship between alcohol consumption and AMD. The researchers found that moderate to high alcohol consumption was linked to a higher incidence of early AMD, compared with people who didn’t drink or who drank occasionally.
Viewing images from childhood reduces pain perception.
New research from scientists at Cummings School of Veterinary Medicine at Tufts University supports and builds on the researchers’ previous findings that opioid use in female rats before pregnancy—even if not used during pregnancy itself—could result in a higher likelihood that male offspring will develop type 2 diabetes and metabolic syndrome, conditions that increase the risk of heart disease and stroke.
Controlling the spin of a single unpaired electron is no easy task. In this research, scientists show that visible light can be used to influence a relative orientation of an unpaired electron in a molecule in a magnetic field. This process can potentially be applied across a class of small molecules and is an important step toward novel technologies such as quantum computers and quantum sensors.
The study finds that consumers are more likely to use mobile payment methods when they receive price incentives for doing so. The transition can last for a few days, even after the price incentives end.
A new University of California, Irvine-led study, called the HOPE (Harnessing Online Peer Education) HIV study, revealed that using peer-led online communities was successful in increasing HIV self-testing and reducing alcohol consumption among Latinx and African American MSM (men who have sex with men).
An unnoticed network of channels is cutting across the coastal plain landscape along the Gulf Coast and influencing how water flows, according to research from The University of Texas at Austin that could help predict flooding from major storms in the future.
Digital technologies are beginning to make inroads into agriculture in lower-income countries in Asia, Africa and Latin America. Precision agriculture has the potential to remove farmers from the local circuits of information and create new dependencies on external commercial services, according to WashU expert Glenn Stone.
In early 2021, researchers at Johns Hopkins Medicine and NORC at the University of Chicago showed that the Agency for Healthcare Research and Quality Safety Program for Improving Antibiotic Use successfully helped more than 400 U.S. hospitals ensure that patients only received antibiotics when needed, and then, only in the correct amounts and for the prescribed dosage period.
New research by the inventors of a promising pathogen-repellent wrap has confirmed that it sheds not only bacteria, as previously proven, but also viruses, boosting its potential usefulness for interrupting the transmission of infections.
A new study tracked lithium metal deposition and removal from a battery anode while it was cycling to find clues as to how failure occurs. The research could help improve the use of pure lithium metal in anodes for electric vehicle batteries, which would reduce battery weights and dramatically extend driving range.
In a new article published in Cancer Discovery, Moffitt Cancer Center researchers shared a comprehensive multiomics study from a rare cohort of 56 patients with transformed CTCL and identified several genomic alterations and oncogenic programs that may be potential novel therapeutic targets.

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia.
Antibiotics provide no benefit in preventing future recurrent wheezing in babies hospitalized with respiratory syncytial virus (RSV), according to a new study led by Washington University School of Medicine in St. Louis. And there is some evidence that antibiotics may make wheezing worse.
