A team of marine scientists has confirmed that southern Africa’s most threatened endemic shark – the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) – has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
The COHERENT particle physics experiment at the Department of Energy’s Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction.
Irvine, Calif., Jan. 26, 2021 — The University of California, Irvine Master of Advanced Study in criminology, law & society has been named the nation’s best online criminal justice master’s program by U.S. News & World Report for the second year in a row. The 2021 rankings also mark the fourth consecutive year in which UCI has placed in the top three.
To investigate what happens inside cells when they are at risk of becoming cancerous, scientists at St. Jude Children’s Research Hospital have been using neutron scattering at Oak Ridge National Laboratory. The team is searching to better understand the altered state of the nucleolus—a membrane-less organelle inside the cell—when the cell is compromised. Novel insights into cell behavior at the atomic and molecular scales will enable better detection and treatment of cancer in its many forms.
New research from Notre Dame shows marketers can help entrepreneurs in emerging markets grow their businesses, which in turn helps them to improve lives, sustain livelihoods, enhance overall living standards and strengthen societies.
Vaccines take time to work. After getting a COVID-19 vaccine, it takes a while for the immune system to fully respond and provide protection from the virus. For the Moderna and Pfizer COVID-19 vaccines, it takes up to two weeks after the second shot to become appropriately protected.
A study led by Ludwig Chicago Co-director Ralph Weichselbaum and Yang-Xin Fu of the University of Texas Southwestern Medical Center has shown how bacteria in the gut can dull the efficacy of radiotherapy, a treatment received by about half of all cancer patients.
An innovative approach to treating bone tumors – starving cancer cells of the energy they need to grow – could one day provide an alternative to a commonly used chemotherapy drug without the risk of severe side effects, suggests a new study from Washington University School of Medicine in St. Louis.
The finding can offer a new way for creating therapies to prevent secondary bacterial infections.
The positions of air inlets and outlets in confined spaces, such as elevators, greatly affect airborne virus transmission. In Physics of Fluids, researchers show air purifiers may actually increase the spread. They use ultraviolet radiation to kill viruses and other microbes, but they also circulate air, sucking it in and exhausting cleaned air. This adds to overall circulation.
As the pandemic continues, scientists are increasingly focused on developing methods to assist in decontaminating surfaces and spaces. In Review of Scientific Instruments, researchers report on experimental tools capable of presenting electromagnetic waves to an aerosol mixture with the capability to vary power, energy, and frequency of the electromagnetic exposure. The researchers seek to better characterize the threshold levels of microwave energy needed to inactivate aerosolized viral particles and reduce their ability to spread infection.
A new study has found compelling evidence that some credit rating analysts leak information about upcoming rating changes to Wall Street to advance their careers.
An estimated 48 million cases of foodborne illness are contracted in the U.S. annually, causing about 128,000 hospitalizations and 3,000 deaths, according to CDC. In some instances, the source is well known, but 80 percent of food poisoning cases are of unknown origin. A new study published by Risk Analysis, proposes a new Food Safety Monitoring System that utilizes data mining on websites to identify products associated with food-related illnesses.
Research from the University of Georgia shows that state laws promoting flu vaccinations for hospital workers can substantially reduce the number of influenza-related deaths.
Today, a coalition of animal welfare, consumer, public health, and environmental organizations called on grocery stores, restaurants and meat producers to reject the use of a misleading label scheme known as One Health CertifiedTM (OHC) and the standards behind it. The label was approved for use on chicken and turkey products earlier this year and is now being used by a handful of grocery store chains, including Aldi and BJ’s, and at least one restaurant chain. Consumer Reports recently assigned the OHC label its second poorest rating because the standards behind the label essentially reflect current problematic industry practices related to antibiotic use, animal production, and environmental impact.
Researchers found female and male collegiate athletes take approximately the same amount of time to recover from a concussion, with subtle differences in recovery time depending on the type of sports being played and the division level of the sport. The findings suggest that equity in access to sports medical care among college athletes may be contributing to these similar outcomes.
Poor social conditions caused by systemic racism contribute to health disparities in people with diabetes, according to a paper published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
“Shell-crushing,” an explosive sound, occurs when marine animals crack open hard shells like clams to eat the edible tissue. There hasn’t been any data to support this feeding noise, until now. A study is the first to quantify these sounds using underwater acoustics in a marine animal in a controlled setting. Scientists know what type of shell a ray is eating based on the sound it makes and show it’s audible above ambient noise in lagoons out to 100 meters.
The testing plan for the "British variant" is based on findings of pre-clinical tests showing stenoparib blocks infection and the replication of SARS-CoV-2, as recently published in peer-reviewed journal mBio.
A new study shows “ethical leadership” might not be needed for an organization’s success but is essential to surviving a crisis. Unethical leaders have difficulty holding teams together after failure; ethical leaders build resilience through a slow, continuous, perhaps unexciting daily commitment.
