Up to one in five employees at an academic medical institution are considering leaving their professions due to the strains of coping with the pandemic in their own lives, according to a new University of Utah Health study. Individuals who had caregiving responsibilities were among those most likely to contemplate leaving or reducing hours. The findings suggest that retaining highly trained doctors, nurses, and scientists in the aftermath of the COVID-19 pandemic could be the next great health care challenge. "It's sobering to learn that, during a time of economic recession, at least one-fifth of our workforce were considering leaving their jobs because of the severe levels of stress they were experiencing," says Angela Fagerlin, Ph.D., the study's senior author and professor ...

SAN FRANCISCO, CA (April 2, 2021) -- In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building corals: species that appear identical to one another but are genetically distinct. Typically ignored as they are invisible to the naked eye, a team of researchers at the California Academy of Sciences and The University of Queensland, along with over a dozen international collaborators, is taking a more holistic approach to understand these hidden species by investigating overlooked ecological differences that have wide-ranging implications for the vulnerability and resilience of reef-building corals. The team hopes that their findings, ...

Extended surges in the South and West in the summer and early winter of 2020 resulted in regional increases in excess death rates, both from COVID-19 and from other causes, a 50-state analysis of excess death trends has found. Virginia Commonwealth University researchers' latest study notes that Black Americans had the highest excess death rates per capita of any racial or ethnic group in 2020. The research, publishing Friday in the Journal of the American Medical Association, offers new data from the last 10 months of 2020 on how many Americans died during 2020 as a result of the effects of the pandemic -- beyond the number of COVID-19 deaths alone -- and which states and racial groups were hit hardest. The rate of excess deaths -- or deaths above the number that ...

More than 60% of U.S. adults who vape are interested in quitting, according to a study published today in JAMA Network Open by MUSC Hollings Cancer Center researchers. And among those who vape to help them to quit smoking, some are successful while others continue smoking and using electronic cigarettes. The study, which analyzed longitudinal survey data from more than 30,000 adults across the country, aimed to provide the most up-to-date estimate of how many Americans are interested in stopping their use of e-cigarettes or have made past attempts to quit. According to the findings, former cigarette smokers had the highest intentions and interest in quitting. This is likely due to an increasing number of smokers using e-cigarettes to transition away from cigarettes, said the study's authors. While ...

People who radicalize to extremist ideologies often are triggered by negative life events or exposure to propaganda, and those who escape from extreme groups frequently are aided by an individual or group that intervenes to help them reject the philosophy, according to a new RAND Corporation study. Expanding access to mental health care, creating opportunities for exposure to diverse cultural groups and media literacy education all are important strategies that may aid the battle against extremism, according to researchers. However, harsh law enforcement actions often are unproductive in changing people's extremist beliefs. The RAND study describes personal accounts based on interviews ...

ITHACA, NY, April 2, 2021 - A team of researchers from the Boyce Thompson Institute (BTI) has discovered a distinct group of bacteria that may help fungi and plants acquire soil nutrients. The findings could point the way to cost-effective and eco-friendly methods of enriching soil and improving crop yields, reducing farmers' reliance on conventional fertilizers. Researchers know that arbuscular mycorrhizal (AM) fungi establish symbiotic relationships with the roots of 70% of all land plants. In this relationship, plants trade fatty acids for the fungi's nitrogen and phosphorus. However, AM fungi lack the ...

Infectious diseases are a leading cause of global mortality. During an infection, bacteria experience many different stresses -- some from the host itself, some from co-colonizing microbes and others from therapies employed to treat the infection. In this arms race to outwit their competition, bacteria have evolved mechanisms to stay alive in the face of adversities. One such mechanism is the stringent response pathway. Understanding how the activation of the stringent response pathway is controlled can provide clues to treat infection. In new research published this week online in the journal END ...

UNIVERSITY PARK, Pa. -- Like moths to a flame, spotted lanternflies are visually drawn toward and seemingly captivated by vertical objects such as utility poles, a behavior that could be valuable in predicting where the pests might be heading, according to entomologists in Penn State's College of Agricultural Sciences. Research from the laboratory of Tom Baker, recently published in the Journal of Insect Behavior, is laying the foundation for future strategies to monitor and possibly trap the invasive insect from Asia, which first was found in North America in Berks County, Pennsylvania, in 2014. The planthopper now is confirmed in 34 Pennsylvania counties and several surrounding states. These findings show that telephone poles attract flight-dispersing ...

Acomprehensive review published in the journal Psychological Science re-examines previous work that claimed to show a direct link between early screen time and attention problems in children. Although other studies do not reflect these findings, the earlier research continues to be widely reported by the media. "The findings from the original study, upon further scrutiny, are not borne out. We found that there is still no evidence that TV, by itself, causes ADHD or any kind of attention problems in young children," said Wallace E. Dixon, Jr., a professor of psychology ...

Long-term, regular use of baby aspirin--at least 15 times per month--prior to a diagnosis of colorectal cancer (CRC) may reduce the risk of death from the disease by limiting the spread of cancerous tumors pre-diagnosis, according to a study led by Cedars-Sinai Cancer researchers. While previous research has offered consistent evidence that low-dose aspirin use reduces colorectal cancer risk, key findings from the study, published in the peer-reviewed Journal of the National Cancer Institute, revealed that the use of baby aspirin prior to the diagnosis of non-metastatic CRC was associated with a lower rate of metastasis, or tumor spread. Starting ...

LOS ANGELES (April 1, 2021) -- A single dose of the Pfizer-BioNTech vaccine for individuals who previously had COVID-19 generates an immunologic response similar to that of individuals receiving the two-dose recommended sequence, according to a Cedars-Sinai study published today by the journal Nature Medicine. "Our findings extend those from smaller studies reported elsewhere and support a potential strategy of providing a single dose of vaccine to persons with a confirmed prior history of coronavirus infection, along with two doses for people not previously infected," said Susan Cheng, MD, MPH, MMSc, associate professor of Cardiology and director of Public Health Research at ...

Organic solar cell (OSC) is one of the most important green energy technologies. The photovoltaic efficiencies of OSCs are closely related to the photoactive layers, which are prepared by blending electron donor and acceptor materials. With the emergence of a large number of new organic photovoltaic materials and effective molecular modification methods, the photovoltaic efficiency of OSCs has been greatly improved. Accordingly, the molecular structure of the materials is becoming much more complex with high costs, which is difficult to meet the requirements of the industrialization of OSCs. Thus, it is of great importance to develop novel photovoltaic ...

Scientists in Japan have developed and tested a novel probiotic formulation to control severe diarrhea in calves, ensuring their health and reducing mortality, and in turn reducing economic loss. The health of calves is a crucial component in animal husbandry; diseases that affect calves cause economic losses to livestock farms either directly, due to death of the calves, or indirectly, due to weight loss that reduces productivity over the animals' lifespans. In Japan, bovine rotavirus (BRV) and bovine cryptosporidiosis infections are major diseases that cause severe diarrhea in calves. A team of scientists from Hokkaido, including Associate Professor Satoru Konnai of the Faculty of Veterinary Medicine at Hokkaido University, have ...

Researchers in Italy have identified a pair of microRNA molecules that help maintain a population of cancerous stem cells that drive the growth of breast cancers and initiate tumor relapse after treatment. The study, which will be published April 2 in the Journal of Cell Biology (JCB), reveals that targeting these microRNAs makes cancer stem cells more susceptible to some chemotherapies and could potentially improve the prognosis of patients with aggressive forms of breast cancer. Many tumors contain a small population of cancer stem cells that initiate tumor growth and give rise to the various cell types found in tumors. Moreover, because cancer stem cells are often resistant to radio- and chemotherapies, they can survive and promote tumor ...

Researchers at the University of California, San Francisco, have discovered that aggressive, triple-negative breast cancers (TNBCs) can evade treatment by reorganizing and softening the collagen matrix that surrounds the cancer cells. The study, which will be published April 2 in the Journal of Experimental Medicine (JEM), shows that the softer matrix activates a signaling pathway that promotes the cancer cells' survival, and suggests that targeting this pathway could enhance the effectiveness of chemo- and radiotherapy in TNBC patients. TNBC is an aggressive type of breast cancer with worse survival rates than other forms of the disease. Because TNBC cells lack the HER2 signaling ...

A team of researchers has identified several candidates for drugs against the coronavirus SARS-CoV-2 at DESY´s high-brilliance X-ray lightsource PETRA III. They bind to an important protein of the virus and could thus be the basis for a drug against Covid-19. In a so-called X-ray screening, the researchers, under the leadership of DESY, tested almost 6000 known active substances that already exist for the treatment of other diseases in a short amount of time. After measuring about 7000 samples, the team was able to identify a total of 37 substances that bind to the main protease (Mpro) of the SARS-CoV-2 virus, as the scientists report online today in the journal ...

Glassy materials play an integral role in the modern world, but inherent brittleness has long been the Achilles' heel that severely limits their usefulness. Due to the disordered amorphous structure of glassy materials, many mysteries remain. These include the fracture mechanisms of traditional glasses, such as silicate glasses, as well as the origin of the intriguing patterned fracture morphologies of metallic glasses. Cavitation has been widely assumed to be the underlying mechanism governing the fracture of metallic glasses, as well as other glassy systems. Up until now, however, scientists ...

A new study indicates holes the solution to operational speed/coherence trade-off, potential scaling up of qubits to a mini-quantum computer. Quantum computers are predicted to be much more powerful and functional than today's 'classical' computers. One way to make a quantum bit is to use the 'spin' of an electron, which can point either up or down. To make quantum computers as fast and power-efficient as possible we would like to operate them using only electric fields, which are applied using ordinary electrodes. Although spin does not ordinarily 'talk' to electric fields, in some materials spins can interact with electric fields indirectly, and these are some of the hottest materials currently studied ...

In May 2020, a team led by thoracic surgeon Konrad Hoetzenecker of the Department of Surgery of MedUni Vienna and Vienna General Hospital performed a lung transplant on a 44-year-old patient who had been seriously ill with Covid-19, making her the first patient in Europe to receive a lung transplant for this indication. The Vienna lung transplantation programme now plays a leading role in an international consortium comprising experts from the USA, Europe and Asia. Based on the expertise from Vienna, approximately 40 transplants have now been carried out on Covid-19 patients throughout the world. In a study published in the leading journal ...

Russian researchers have developed an inexpensive, safe, and reliable packed eggs surface disinfection technology. This technology helps to kill bacteria, including salmonella, on eggshells. Also, it allows growing broiler chickens with strong immunity to viral diseases. Packed eggs are disinfected with 50 nanoseconds (one billionth of a second) electron beam. Disinfection takes place in plastic containers. The description of the technology was published in Food and Bioproducts Processing. "Disinfection of the packed eggs protects eggs from subsequent contamination during storage", said Sergey Sokovnin, a professor at Ural Federal University and Ural Branch of Russian Academy of Science. "We found out that 5 kGy is enough for disinfection. Such dose allows to ...

Niigata, Japan - Cancer is the world's second deadliest disease which contributes towards the fatality of over 10 million people per year. Oncologists adopt a variety of treatment procedures to treat cancer cells. Among the different methods used to fight cancer, chemotherapeutic treatment is a prominent and well-adopted technique. It is a drug based method, wherein powerful chemical compounds are injected into the body to annihilate the malignant cells. Although these chemicals support the destruction of the cancerous cells, optimizing their dosage has always been a challenge to the medical ...

In United Nations Sustainable Development Goals, Number 6, addresses the need for access to clean water and sanitation for all. In the worldwide situation, one in three people do not have access to safe drinking water, and two out of five do not have basic hand-washing facilities with soap and water. Water quality also address to elements dissolved. In the case of fluoride, controlled amount are recommended for protect tooth, e.g. included in toothpaste. Higher levels can cause fluorosis, interfere in tooth enamel formation, correct growth of the bones, and cause crippling deformities of the spine and joints. The incidence of higher concentrations of fluoride in water is higher in rural areas without ...
