WASHINGTON, April 6, 2021 -- Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what's left is a protein- and fiber-rich powder that is typically used in cattle feed or put in landfills. Today, scientists report a new way to extract the protein and fiber from brewer's spent grain and use it to create new types of protein sources, biofuels and more. The researchers will present their results today at the spring meeting of the American Chemical Society (ACS). ACS Spring 2021 is being held online April 5-30. Live sessions will be hosted April 5-16, ...

By 2050 global warming could reduce crop yields by one-third. UC Riverside researchers have identified a gene that could put the genie back in the bottle. Warmer temperatures signal to plants that summer is coming. Anticipating less water, they flower early then lack the energy to produce more seeds, so crop yields are lower. This is problematic as the world's population is expected to balloon to 10 billion, with much less food to eat. "We need plants that can endure warmer temperatures, have a longer time to flower and a longer growth period," said UCR botany and plant sciences professor ...

DALLAS, April 6, 2021 -- A tsunami of chronic health conditions as a result of the SARS-CoV-2 pandemic, especially cardiometabolic disease, may produce an enormous wave of death and disability that demands immediate, comprehensive strategies. In addition, COVID-19 has disrupted cardiovascular science and medicine, yet it presents opportunities to transform and create novel approaches that can yield new successes. These are the opinions of two esteemed leaders in cardiovascular disease care, research and strategy, detailed in two new Frame of Reference articles published today in the American Heart Association's flagship journal Circulation. While COVID-19 has severely impacted everyone's daily lives, its societal ...

The inequality is enormous: Mothers in select African countries are more than 100 times more likely to have had a child die than mothers in high-income countries. This is what Diego Alburez-Gutierrez (Researcher at the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany), Emily Smith-Greenaway (Researcher at the USC Dornsife College of Letters, Arts and Sciences in Los Angeles and Guest Researcher at MPIDR), and co-authors found in their recent paper published in BMJ Global Health. "We offer the first global estimates of the cumulative number of child deaths experienced by mothers ...

CHARLOTTESVILLE, VA (APRIL 6, 2021). New research by a team from the Cleveland Clinic and the London School of Economics and Political Science (LSE) has determined that surgeries performed late in the workweek, and those culminating in discharge to a specialty care facility, are associated with higher costs and unnecessarily longer stays in the hospital following a common elective spine surgery. Sebastian Salas-Vega, PhD, and colleagues retrospectively reviewed the data for all adult patients who underwent elective lumbar laminectomy over a nearly three-year period at any Ohio hospital included within ...

Newer is not always better; a study in CMAJ (Canadian Medical Association Journal) led by researchers at the University of Warwick shows that simple fetal heartbeat monitoring is still the best method for determining whether a baby is in distress during delivery and whether cesarean delivery is needed http://www.cmaj.ca/lookup/doi/10.1503/cmaj.202538. Cesarean delivery is the most common surgical procedure worldwide, performed to expedite birth and avoid neonatal complications. Listening to the fetal heart rate using a stethoscope -- intermittent auscultation -- has been used for years to assess the fetal state and whether the baby is experiencing distress that might require a cesarean delivery. Other monitoring techniques have become ...

Legalization of recreational cannabis may be associated with an increase in fatal motor vehicle collisions based on data from the United States, and authors discuss the implications for Canada in an analysis in CMAJ (Canadian Medical Association Journal). "Analyses of data suggest that legalization of recreational cannabis in United States jurisdictions may be associated with a small but significant increase in fatal motor vehicle collisions and fatalities, which, if extrapolated to the Canadian context, could result in as many as 308 additional driving fatalities annually," says Ms. Sarah Windle, Lady Davis Institute/McGill ...

Hamilton, ON (April 6, 2021) - If you are one of the millions of people worldwide suffering from allergies, you may take an antihistamine pill to ward off hives, sneezing and watery eyes. But you may be taking your medications incorrectly, says Derek Chu, a McMaster University allergy expert and clinical scholar. "People need to rethink what they stock in their home cabinets as allergy medicines, what hospitals keep on formulary, and what policymakers recommend. The message needs to get out. This publication is on time for the spring allergy season and as COVID vaccines roll out, for which rashes are common and antihistamines can be helpful," said Chu. Co-author Gordon ...

The idea of implantable sensors that continuously transmit information on vital values and concentrations of substances or drugs in the body has fascinated physicians and scientists for a long time. Such sensors enable the constant monitoring of disease progression and therapeutic success. However, until now implantable sensors have not been suitable to remain in the body permanently but had to be replaced after a few days or weeks. On the one hand, there is the problem of implant rejection because the body recognizes the sensor as a foreign object. On the other hand, the sensor's color which indicates concentration changes has been unstable so far and faded over time. Scientists at Johannes Gutenberg University Mainz (JGU) have developed a novel type of implantable sensor which can ...

In 2001, the famous herpetologist Joseph B. Slowinski died from snakebite by an immature black-and-white banded krait, while leading an expedition team in northern Myanmar. The very krait that caused his death is now confirmed to belong to the same species identified as a new to science venomous snake, following an examination of samples collected between 2016 and 2019 from Yingjiang County, Yunnan Province, China. The new krait species, found in Southwestern China and Northern Myanmar, is described by Dr Zening Chen of END ...

A new study analyzing bean production and food security across 11 countries in sub-Saharan Africa, found COVID-19 pandemic-related restrictions to significantly impact bean production. Border controls and high transport costs have led to drops in production of the key food security crop, threatening to reverse gains made in achieving Sustainable Development Goals 1 and 2, towards no poverty and zero hunger, respectively. Even before the pandemic, 55% of the world's hungry people and 70% of the world's poorest people lived in Africa, the researchers said. In addition, food systems across Africa were already affected by the adverse impacts of climate change, disease and pests, such as the worst desert locust outbreak in 70 years impacting food security in Kenya, Somalia, ...

3-D printing has the potential to revolutionize product design and manufacturing in a vast range of fields--from custom components for consumer products, to 3-D printed dental products and bone and medical implants that could save lives. However, the process also creates a large amount of expensive and unsustainable waste and takes a long time, making it difficult for 3-D printing to be implemented on a wide scale. Each time a 3-D printer produces custom objects, especially unusually-shaped products, it also needs to print supports­-printed stands that balance the object as the printer creates layer by layer, ...

Likely the first extinction event of the 2000s in Europe, the sad history of the Pyrenean Ibex (Capra pyrenaica pyrenaica) is a powerful example of the ever-increasing species loss worldwide due to causes related to human activity. It can, however, give us valuable information on what should be done (or avoided) to halt this extinction vortex. The distribution of this subspecies of Iberian Ibex was limited to the French and Spanish Pyrenees. Its first mention in an official written document, dating back to 1767, already refers to it as extremely rare. Like many other mountain goats, it was almost hunted to extinction before its killing became prohibited in 1913. Neither the institution ...

Insomnia is a common problem in patients with schizophrenia, and a new study reinforces a close association between insomnia, more suicidal thoughts and actions and increased problems like anxiety and depression in these patients. It also provides more evidence that keeping tabs on how patients are sleeping -- and intervening when needed -- is important to their overall care. "We are now aware that significant insomnia is putting our patients at even higher risk for suicide, so if they are having changes in sleep patterns, if they are having significant insomnia, then we really need to hone in on those questions even more related to suicidal thinking and do what we can to help," says Dr. ...

A new paper in the Journal of General Internal Medicine published by the GenderSci Lab at Harvard University shows that Black women are dying at significantly higher rates than white men, and that disparities in mortality rates among women of all races are greater than those between white women and white men. The study is the first to quantify the inequities in COVID-19 mortality looking at both race and sex group. "This analysis complicates the simple narrative that men are dying at greater rates of COVID-19 than women," said lead author Tamara Rushovich, Harvard Ph.D. candidate in population health sciences and lab member ...

The adult human body produces hundreds of billions of blood cells every day. This essential process unavoidably leads to the appearance of mutations in the DNA of the progenitor cells. These are known as somatic mutations because they are acquired, not inherited. While most of these mutations are innocuous, occasionally a mutation gives affected cells a competitive advantage that allows them to expand progressively, generating clonal populations of blood cells. This phenomenon is known as clonal hematopoiesis. Now, a team of scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) and the Hospital Universitario Virgen de Arrixaca in Murcia has discovered that the presence of these acquired mutations in blood cells increases ...

Researchers at the Human Genome and Stem Cell Research Center (HUG-CELL), hosted by the University of São Paulo's Institute of Biosciences (IB-USP) in Brazil, have developed a technique to reconstruct and produce livers in the laboratory. The proof-of-concept study was conducted with rat livers. In the next stage of their research, the scientists will adapt the technique for the production of human livers in order in future to increase the supply of these organs for transplantation. The study was supported by FAPESP and is reported in an article published in Materials Science and Engineering: ...

PITTSBURGH, April 5, 2021 - "Near-poor" Americans--people just above the federal poverty level but still well below the average U.S. income--who rely on Medicare for health insurance face high medical bills and may forgo essential health care, according to new research led by health policy scientists at the University of Pittsburgh Graduate School of Public Health. This is due to a coverage "cliff" in Medicaid, which supplements Medicare for people with incomes below poverty but excludes individuals above the federal poverty threshold, including the near-poor. In a report published today in the April issue of the journal Health Affairs, the authors describe the effects of this cliff and propose solutions to fix it, with the aim of lessening barriers to care among near-poor people ...

PHILADELPHIA-- Approximately 6.5 million people are under correctional supervision in the United States on any given day. Justice-involved individuals (people currently or recently in prison or jail, on probation or parole, or arrested) experience higher rates of substance use disorders than the general population. In fact, among people with opioid use disorder (OUD), more than half have reported contact with the criminal justice system. Numerous clinical studies have shown that medications for OUD -- specifically, methadone or buprenorphine -- lead to superior outcomes for retention in treatment, reduced illicit opioid use, and decreased opioid-related overdose rates and serious acute care compared with treatments that ...

PHILADELPHIA-- While the emergency department (ED) functions as an integral part of the United States healthcare safety net by handling all medical complaints regardless of insurance status, ED visits are expensive, and many are for lower-acuity conditions that may be amenable to care in other settings. Previous research has suggested that greater availability of urgent care centers - freestanding facilities with extended hours that staff emergency physicians, primary care physicians, or nurse practitioners, and focus on a broad range of lower acuity complaints, like rash, muscle strain, bronchitis, and urinary tract infection - helps decrease ED visits, but whether the centers reduce or increase net spending for patients ...

Even before the pandemic made telehealth a hot topic, people with minor urgent health needs had started to turn to companies that offer on-demand video chats with physicians that they don't normally see. Insurers and employers even started buying access to this direct-to-consumer form of virtual care, hoping it might reduce in-person care, including emergency department visits. But a new University of Michigan study casts some doubt on whether that will actually happen. Published in the April issue of Health Affairs, the study finds that patients who had an on-demand ...

In a new study, researchers found nearly half of those who share explicit images of others without permission feel remorse after the fact and 24% try to deflect blame onto victims. Amy Hasinoff, a researcher at the University of Colorado Denver, joined Danish researcher Sidsel K. Harder, to take a deeper dive into the issue of sexual abuse and image sharing. Hasinoff and Harder looked at how people who shared explicit images online spoke to police officers about the harmful acts they committed. While looking over cases where the image-sharer was caught and convicted, ...

People with ovarian cancer frequently receive aggressive end-of-life care despite industry guidelines that emphasize quality of life for those with advanced disease, according to a recent study. In fact, by 2016, ICU stays and emergency department visits in the last month of life had become more common for people with ovarian cancer than they were in 2007, the earliest year from which researchers analyzed data. The proportion of non-Hispanic Black people who turned to the emergency department for care was even higher -- double that of non-Hispanic whites. Black people were also nearly twice as likely to undergo intensive treatment, including ...

One day, humankind may step foot on another habitable planet. That planet may look very different from Earth, but one thing will feel familiar -- the rain. In a recent paper, Harvard researchers found that raindrops are remarkably similar across different planetary environments, even planets as drastically different as Earth and Jupiter. Understanding the behavior of raindrops on other planets is key to not only revealing the ancient climate on planets like Mars but identifying potentially habitable planets outside our solar system. "The lifecycle of clouds is really important when we think about planet habitability," said Kaitlyn Loftus, a graduate student in the Department ...
