FAYETTEVILLE, Ark. — With an increasing frequency and intensity of flooding events and an eye to capitalize on a common rice production technique, soybean breeders are on a quest to develop varieties with flood tolerance at any stage in the plant’s development. Farmers who use zero-grade fields for rice as their main production system are also interested in flood-tolerant soybean varieties for crop rotation, said Caio Vieira, assistant professor of soybean breeding and a researcher for the Arkansas Agricultural Experiment Station, the University of Arkansas ...

For the last 10 years, the only effective treatment for hypophosphatasia (HPP) has been an enzyme replacement therapy that must be delivered by injection three-to-six times each week. “It's been a tremendous success and has proven to be a lifesaving treatment,” said José Luis Millán, PhD, professor in the Human Genetics Program at Sanford Burnham Prebys. “Many children who have been treated otherwise would have died shortly after birth, and they are now able to look forward to long lives. “It is, however, a very invasive treatment. Some patients have reactions from frequent injections and discontinue ...

Sustainability certificates such as Fairtrade, Rainforest Alliance and Cocoa Life promise to improve the livelihoods of small-scale cocoa producers while preserving the biodiversity on their plantations. Together with the European Commission's Joint Research Centre, researchers from the University of Göttingen have investigated whether sustainability certificates actually achieve both these goals. To find out, they carried out an analysis within the Ghanaian cocoa production sector. Their results show that although certification improves both cocoa yield and cocoa income for small-scale producers, they were unable to ...

What began as a demonstration of the complexity of fluid systems became an art piece in the American Physical Society’s Gallery of Fluid Motion, and ultimately its own puzzle that the researchers just solved. Their new study is published in the journal Physical Review Letters. “We came up with this experiment because we were having a hard time convincing people of certain effects happening for the problem of drag reduction,” said assistant professor Paolo Luzzatto-Fegiz, an assistant professor of mechanical engineering, whose research specialties include modeling flow and investigating drag — as ...

The California Institute for Regenerative Medicine has awarded a $6 million grant to USC investigators pioneering a new first-of-its-kind genetic therapy for glioblastoma, a severe form of brain cancer. The treatment would be the first gene therapy for glioblastoma to use a novel, more precise delivery system that is less likely to harm non-cancerous cells. Glioblastoma is an aggressive and fast-growing cancer originating in the brain that occurs primarily in adults and has no known cure. Patients diagnosed with this type of tumor have a five-year survival rate of just 5 percent. The cancer’s location—in the sensitive brain—combined ...

The Society for Healthcare Epidemiology of America (SHEA) is concerned that two weeks have passed since the Department of Health and Human Services (HHS) announced a pause on mass communications and public appearances that are not directly related to emergencies or critical to preserving health. With the order remaining in effect until a new HHS secretary is confirmed, this unpredictable timeline prolongs uncertainty for both healthcare professionals and the public, and endangers the nation by hindering our ability to detect and respond to public health threats, such as avian influenza (H5N1). Public ...

Through a multi-university collaboration, researchers at Virginia Tech have discovered a new, solid lubricating mechanism that can reduce friction in machinery at extremely high temperatures. It works well beyond the breakdown temperature of traditional solid lubricants such as graphite, and the findings were published in Nature Communications.  “This breakthrough solid-state lubricant could change how we design materials for high-tech engines, making them last longer and work better under extreme conditions,” said Rebecca Cai, associate professor in the Department of Materials Science and Engineering and one of the ...

The stereotype that women are much more talkative than men is pervasive across many cultures, but a widely reported study by University of Arizona researchers in 2007 refuted the claim, finding that men and women speak roughly the same number of words per day – around 16,000.  A new, larger follow-up to that study paints a more nuanced picture, suggesting that women may be the chattier gender, but only during a certain period of life.  "There is a strong cross-cultural assumption that women talk a lot more than men," said ...

In physics, the term “isotropy” means a system where the properties are the same in all directions. For fusion, neutron energy  isotropy is an important measurement that analyzes the streams of neutrons coming from the device and how uniform they are. This is critical because so-called isotropic fusion plasmas suggest a stable, thermal plasma that can be scaled to higher fusion energy gains, whereas anisotropic plasmas, those emitting irregular neutron energies, can lead to a dead end. A new Zap research paper, published last week ...

A new study has estimated it would cost $15.6 billion per year for 30 years to prevent extinction for 99 of Australia’s priority species.  The research, led by Griffith University’s Centre for Planetary Health and Food Security with WWF-Australia and the University of Queensland, highlights the urgent need for increased funding to combat threats such as habitat destruction, invasive species and climate change. Australia has already lost more than 100 endemic species in the past three centuries, placing it at the forefront of the global extinction crisis.  The ...

The octopus just revealed another one of its secrets: what determines its sex.  University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on the evolutionary tree. That makes it one of the oldest known animal sex chromosomes.   The finding also is evidence that octopuses and other cephalopods, a class of sea animals that includes squid and nautiluses, do use chromosomes to determine their sex, answering a longstanding mystery among biologists.   “Cephalopods are already such interesting creatures, ...

Rice cultivation is responsible for around 12% of global methane emissions, and these emissions are expected to increase with global warming and as the human population continues to grow. Now, scientists have identified chemical compounds released by rice roots that determine how much methane the plants emit. On February 3 in the Cell Press journal Molecular Plant, they report that this information enabled them to breed a new strain of rice that emits up to 70% less methane.  “This study shows that you can have low methane and ...

About The Study: In 2023, post–COVID condition (PCC) continued to affect U.S. children at similar levels as 2022 and to have similar sociodemographic patterns. The large proportion of children experiencing PCC with any activity limitation highlights the need to examine the severity of activity limitation, functional outcomes, and days lost from school.

About The Study: This cohort study of hospitalized adults identified inequities related to race and rurality in health care–associated infections (HAIs) and adverse outcomes from HAIs. These findings suggest that factors such as structural racism and disinvestment in rural communities may be associated with individual HAI risk and post-HAI outcomes. Future work to further understand the reasons underpinning these disparities and methods to address structural factors through policy and process changes are critical to ...

Alarming Rise in Rates of Advanced Prostate Cancer in California  Following a change in screening guidelines, the incidence went up across the state, even more than it has nationally. The incidence of advanced prostate cancer in California rose markedly in the decade since doctors stopped routinely screening all men for the disease, according to a new study by UC San Francisco. After declining for many years, the death rate from the disease also plateaued in most regions across the state. The findings reinforce the need for screening that can identify potentially fatal tumors without raising false alarms about ones that pose no threat to the patient.  The ...

For years, healthy older adults were advised by doctors to take a low-dose aspirin daily as a way to reduce the risk of heart attack. But in March 2019, the American College of Cardiology and the American Heart Association (AHA) announced new guidelines and no longer routinely recommended a daily dose of aspirin for healthy adults over the age of 70 because the risk of gastrointestinal bleeding outweighs the benefits. Nearly five years later, many Americans still have not received the message. The Annenberg Public Policy Center (APPC) of the University of Pennsylvania finds in a new health survey that nearly half (48%) of U.S. ...
