Exercise during pregnancy may let mothers significantly reduce their children's chances of developing diabetes and other metabolic diseases later in life, new research suggests. A study in lab mice has found that maternal exercise during pregnancy prevented the transmission of metabolic diseases from an obese parent - either mother or father - to child. If the finding holds true in humans, it will have "huge implications" for helping pregnant women ensure their children live the healthiest lives possible, the researchers report in a new scientific paper. This means that one day soon, a woman's first trip to the doctor after conceiving might include a prescription for an exercise ...

The $1.9 trillion American Rescue Plan, a stimulus package introduced by the Biden Administration, recently received Congress' approval. The stimulus package, like its two predecessors aimed at providing relief for individuals and businesses hindered by the COVID-19 pandemic, includes another round of funding for the Paycheck Protection Program (PPP). The American Rescue Plan includes $7.25 billion for PPP loans as well as a number of changes to make it easier for the smallest of businesses to gain access to the funding. With billions on the table for struggling small businesses, new research from the University of Florida Warrington College of ...

How important is fame? What about self-acceptance? Benevolence? The messages children between the ages of 8 and 12 glean from TV play a significant role in their development, influencing attitudes and behaviors as they grow into their teenage years and beyond, UCLA psychologists say. Now, a new report by UCLA's Center for Scholars and Storytellers assesses the values emphasized by television programs popular with tweens over each decade from 1967 to 2017, charting how 16 values have waxed and waned in importance during that 50-year span. Among the key findings is that fame, after nearly 40 years of ranking near the bottom (it was 15th in 1967, 1987 and 1997), rose to become the No. 1 ...

Louisiana State University researchers recently published findings that blight leads to an increased abundance of disease-carrying mosquitoes. The researchers investigated the presence of several mosquito species in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge: the historic Garden District, a high-income neighborhood, and the Old South neighborhood, a low-income area. They found significantly higher adult and larvae abundance of the Asian tiger mosquito (a carrier of Zika and dengue) and higher mosquito habitat availability--particularly discarded tires--in the Old South neighborhood. This indicates that environmental conditions in the low-income neighborhood were most ideal for this mosquito to breed and proliferate. "These ...

Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a study led by the University of California, Davis. The study, published today in the journal PNAS, chronicles the effort --and failure -- to eradicate invasive European green crabs from a California estuary. The crabs increased 30-fold after about 90 percent had been removed. The study is the first experimental demonstration in a coastal ecosystem of a dramatic population increase in response to full eradication. "A failure in science often leads to ...

The world's oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more. Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric concentrations was assumed to be negligible. Now, MIT researchers have found the oceanic fluxes of at least one type of CFC, known as CFC-11, do in fact affect atmospheric concentrations. In a study appearing today in the Proceedings of the National Academy of Sciences, the team reports that the global ocean will reverse its longtime role as a sink for the potent ozone-depleting chemical. The researchers ...

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland--and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017. In 2019, University of Vermont scientist Andrew Christ looked at it through his microscope--and couldn't believe what he was seeing: twigs and leaves instead of just sand and rock. That suggested that the ice was gone in the recent geologic past--and that a vegetated landscape, perhaps a boreal forest, stood where a mile-deep ice sheet as big ...

For the first time, researchers have pinpointed what causes normal proteins to convert to a diseased form, causing conditions like CJD and Kuru. The research team, from Imperial College London and the University of Zurich, also tested a way to block the process, which could lead to new drugs for combatting these diseases. The research concerned prion diseases - a group of brain diseases caused by proteins called prions that malfunction and 'misfold', turning into a form that can accumulate and kill brain cells. These diseases can take decades to manifest, but are then are aggressive and fatal. They include Kuru, mad cow disease and its human equivalent Creutzfeldt-Jakob disease (CJD), and a heritable condition called fatal familial ...

If you live in a flood prone area, would you -- or could you -- take measures to mitigate flood risks? What about others in your community? We are running out of time to ask this question according to The World Resources Institute, because global flood risk is increasing and loss projections for rivers alone put the cost over 500 billion dollars by midcentury. Research published today in Proceedings of the National Academy of Sciences from scientists from the University of Connecticut, the University of Maryland's National Socio-Environmental Synthesis Center (SESYNC), the University of Massachusetts Amherst, and the London School of Economics suggests that in the United States, race and stream flow are ...

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term. BMMFs and inflammatory markers were significantly more frequently detectable in the vicinity of malignant intestinal tumors than in the intestinal tissue of tumor-free individuals. A few years ago, ...

Researchers developed a prototype for a new cancer immunotherapy that uses engineered T cells to target a genetic alteration common among all cancers. The approach, which stimulates an immune response against cells that are missing one gene copy, called loss of heterozygosity (LOH), was developed by researchers at the Ludwig Center, Lustgarten Laboratory and the Bloomberg~Kimmel Institute for Cancer Immunotherapy at the Johns Hopkins Kimmel Cancer Center. Genes have two alleles, or copies, with one copy inherited from each parent. Cancer-related genetic alterations commonly involve the loss of one of these gene copies. "This copy loss, or LOH, is one of the most common genetic events in cancer," says Kenneth Kinzler, Ph.D., co-director of the Ludwig Center, professor of oncology and ...

HOUSTON - (March 15, 2021) - Increased internet-access spending by Texas public schools improved academic performance but also led to more disciplinary problems among students, a study of 9,000 schools conducted by a research team from Rice University, Texas A&M University and the University of Notre Dame shows. Whether students benefit from increased internet access in public schools has been an open question, according to the researchers. For example, some parents and policy advocates contend it increases children's access to obscene or harmful content and disciplinary problems. Others believe it promotes personalized learning and higher student engagement. To address these policy questions, the research team created a multiyear dataset (2000-14) of 1,243 school districts ...

When Steamboat Geyser, the world's tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can we learn about it before it goes quiet again? The University of Utah has been studying the geology and seismology of Yellowstone and its unique features for decades, so U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring. The findings are published in the Journal of Geophysical Research-Solid Earth. "We ...

If you are a consumer and/or entrepreneur who can make decisions based on cost, competition, supply and demand, you probably possess an element of marketplace literacy. "Marketplace literacy" is defined as the knowledge and skills that enable individuals to participate in a marketplace both as consumers and entrepreneurs. San Diego State University marketing professor Nita Umashankar, along with professors Madhubalan Viswanathan (Loyola Marymount University), Arun Sreekumar (University of Illinois at Urbana Champaign) and Ashley Goreczny (Iowa State University), explored the impact on marketplace literacy on ...

HSE University researchers together with specialists from the Humanitarian Action Charitable Fund (St. Petersburg) and the University of Michigan School of Public Health (USA) studied the specifics of remote work with Russian people who use drugs to reduce the harm of drug use. They discovered that the use of online platforms increases the § who use drugs to seek help. Online platforms also serve as a kind of 'gateway' for people with problematic drug use to receive a wider range of qualified help. The authors concluded that remote work in this field should be developed and built upon in ...

Forest landscape restoration is attaining new global momentum this year under the Decade of Ecosystem Restoration (2021-2030), an initiative launched by the United Nations. Burkina Faso, in West Africa, is one country that already has a head start in forest landscape restoration, and offers valuable lessons. An assessment of achievements there and in other countries with a history of landscape restoration is critical to informing a new wave of projects aiming for more ambitious targets that are being developed thanks to renewed global interest and political will to improve the environment. Burkina Faso has been fighting with desertification and climate change, and has seen a progressive degradation of its forested landscapes due to the expansion of agriculture. In 2018, the country ...

In the last 20 years, Black adults living in rural areas of the United States experienced high mortality rates due to diabetes, high blood pressure, heart disease and stroke compared to white adults. According to a research letter published in the Journal of the American College of Cardiology, racial disparities improved minimally in rural areas over the last two decades, with larger improvements occurring in urban areas. "While modest gains have been made in reducing racial health inequities in urban areas, large gaps in death rates between Black and white adults persist in rural areas, particularly for diabetes and hypertension. We haven't meaningfully ...

March 15, 2021 - After arthroscopic surgery on the meniscus of the knee, patients using telemedicine for postoperative follow-up are just as satisfied with their care as those making in-person visits, reports a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer. "Patient satisfaction with overall care is equivalent between telemedicine and office-based follow-up after an arthroscopic meniscal surgical procedure in the immediate postoperative period," according to the randomized trial report by Christina P. Herrero, MD, and colleagues of NYU Langone Health, New York , and colleagues. Telemedicine is 'a reasonable alternative' for postoperative visits The ...

Immigrants imprisoned in immigration facilities across the country face health conditions and often have chronic illnesses that would expose them to greater risk with COVID-19, a new University of California, Davis, study suggests. "The research is clear: immigration detention is not only unnecessary for facilitating a just immigration system, but also causes extensive harm to detained people, perhaps especially to those facing chronic health conditions," said the study's lead author, Caitlin Patler, professor of sociology. "This is particularly alarming in the context of the COVID-19 pandemic. The government must act quickly to permanently reduce reliance ...

Prior to COVID-19, communication via the internet was already a regular feature of everyday interactions for most people, including those on the autism spectrum. Various studies have shown how autistic people use information and communication technology (ICT) since the early 2000s, some finding that autistic people may prefer to communicate using the internet instead of in-person. However, no systematic review has been conducted to summarize these findings. To understand what has been discovered so far, researchers from Drexel University's A.J. Drexel Autism Institute collected and reviewed published research about how autistic youth and adults use the internet to communicate and provide a framework ...

(BOSTON) ¬-- Trillions of commensal microbes live on the mucosal and epidermal surfaces of the body and it is firmly established that this microbiome affects its host's tolerance and sensitivity of the host to a variety of pathogens. However, host tolerance to infection with pathogens is not equally developed in all organisms. For example, it is known that the gut microbiome of mice protects more effectively against infection with certain pathogens, such as the bacterium Salmonella typhimurium, than the human gut microbiome. This raises the interesting possibility that analyzing differences between host-microbiome ...

TORONTO, ON - Research by a team of chemists at the University of Toronto, led by Nobel Prize-winning researcher John Polanyi, is shedding new light on the behaviour of molecules as they collide and exchange atoms during chemical reaction. The discovery casts doubt on a 90-year old theoretical model of the behavior of the "transition state", intermediate between reagents and products in chemical reactions, opening a new area of research. The researchers studied collisions obtained by launching a fluorine atom at the centre of a fluoromethyl molecule - made up of one carbon atom and three fluorine atoms - and observed the resulting reaction using Scanning Tunneling Microscopy. What they saw following each collision ...

Fingerprints may be more useful to us than helping us nab criminal suspects: they also improve our sense of touch. Sensory neurons in the finger can detect touch on the scale of a single fingerprint ridge, according to new research published in JNeurosci. The hand contains tens of thousands of sensory neurons. Each neuron tunes in to a small surface area on the skin -- a receptive field -- and detects touch, vibration, pressure, and other tactile stimuli. The human hand possesses a refined sense of touch, but the exact sensitivity of a single sensory neuron has not been studied before. To ...

Key Points 19.3% of children and adolescents in the United States have obesity and therefore have a higher likelihood of having obesity as adults and developing weight-related diseases. This AJCN study assessed how strongly mothers' diets during pregnancy were associated with their children's growth rates during specific periods from birth through adolescence. Study results suggest maternal nutrition during pregnancy may influence her offspring's weight gain during specific periods from birth to adolescence. A pregnancy diet with higher inflammatory potential was associated with accelerated BMI growth trajectories in children, specifically those between three and ten years of age. Rockville, ...

Recent summer droughts in Europe are far more severe than anything in the past 2,100 years, according to a new study. An international team, led by the University of Cambridge, studied the chemical fingerprints in European oak trees to reconstruct summer climate over 2,110 years. They found that after a long-term drying trend, drought conditions since 2015 suddenly intensified, beyond anything in the past two thousand years. This anomaly is likely the result of human-caused climate change and associated shifts in the jet stream. The results are reported in the journal Nature Geoscience. Recent summer droughts and heatwaves in Europe have had devastating ecological and economic consequences, which will worsen as the global climate continues to warm. "We're ...
