Most of the earthquakes rumbling under the West’s Great Basin come in surges, clustered together in time and place. Scientists call these seismic groups “swarms,” which are a distinct category from the numerous aftershocks following a big shake, such as the 5.7 magnitude Magna quake of 2020 on the Wasatch Fault. Rather than getting spread out evenly over time, many of these small, often imperceptible quakes strike a region in a short period of time, say a few days or weeks. Central Utah has been the stage for dozens of earthquake swarms that have been recorded over the past 40 years by an ever-expanding network of seismic arrays managed by the University ...

Encouraging Latinx adolescents of Mexican origin to embrace their ethnic pride, cultural values, and connections to their cultural community contributes to positive development and better adjustment during adolescence, a new University of California, Davis, psychology study suggests. Moreover, researchers said, cultural preservation can help Latinx youth cope with adverse life experiences and social threats such as racism and discrimination. The study results were published this month in ...

A Chapman University scientist and his colleagues have determined how the Earth responds as it heats up due to climate change. The scientists say a warming world calls for a new approach in detecting how much carbon dioxide comes out of ecosystems when the temperature changes  — which tells us how well plants and soil can alleviate damage by removing carbon pollution from the atmosphere. The study is the first to find the temperature-carbon dioxide release relationship at the landscape level.  Their ...

An international team of scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Water Research Group from the Unit for Environmental Sciences and Management at the North-West University in South Africa have discovered a new species of marine cryptofauna in the Florida Keys. Cryptofauna are the tiny, hidden, organisms that make up the majority of biodiversity in the ocean. The roughly three-millimeter-long isopod is one of only 15 species from the genus Gnathia currently known in the region. The newly discovered species, Gnathia jimmybuffetti, which is a member of a group of crustaceans called gnathiid isopods, were collected ...

PORTLAND, Ore. – Researchers in the Oregon State University College of Pharmacy have developed a drug delivery system that shows promise for greatly enhancing the efficacy of the medicine given to women with the life-threatening condition of ectopic pregnancy, which occurs when a fertilized egg implants somewhere other than the lining of the uterus. Olena Taratula of the OSU College of Pharmacy, and Maureen Baldwin and Leslie Myatt of Oregon Health & Science University led a team that used a mouse model to show ...

At first glance, Canada appears to have responded adequately to the covid-19 emergency, but beneath the surface lie major pandemic failures, warns a series of articles published by The BMJ today. The BMJ Canada Covid Series provides a critical analysis of what worked and what didn’t in Canada’s covid-19 response and calls for a national independent  review to learn lessons and ensure accountability for the past and future preparedness. The articles, written by leading clinicians and researchers representing 13 institutions across Canada, highlight long-standing weaknesses ...

Self-reported data from lesbian, gay or bisexual (LGB) patients shows these groups have poorer health outcomes compared to those who identify as heterosexual, but bisexual people disproportionally experience the worst outcomes in England.    These new findings, published today in the peer-reviewed journal The Journal of Sex Research, indicate that bisexual people face additional health disparities within an already marginalised community.    Experts, from the Brighton and Sussex Medical School and Anglia Ruskin University who led the analysis of more than 835,000 adults in England, suggests the disparities could result from unique prejudice and discrimination ...

Davis, CA – Mother-daughter duo Jennifer Canvasser and Leslie Napolitano have published Forever Our Little One, a storybook for bereaved families. Jennifer is the executive director of the Necrotizing Enterocolitis (NEC) Society, which she founded after her son Micah tragically died from complications of NEC. Leslie is an artist and illustrator who helped care for her grandson Micah during his time in the neonatal and pediatric intensive care units. Jennifer wrote the storybook for families ...

Irvine, Calif., July 24, 2023 – Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs. Cheaper food encourages people to buy and eat more, offsetting the lowering of greenhouse gas ...

As the world continues to combat various infectious diseases, the development of novel vaccine technologies remains at the forefront of scientific research. mRNA-based vaccines and utilization of lipid nanoparticles (LNPs) for their delivery, have recently shown encouraging results in diseases such as COVID-19. However, a critical concern revolves around the wide biodistribution of LNPs in the body, which, in some cases, may result in unintended side effects. A recent publication in the peer-reviewed ...

Key takeaways A new study finds that consumers often misremember if a product is labeled “scientifically studied” or “scientifically proven” — despite the significant difference in meaning between the two phrases. UCLA psychologists conducted an experiment with one group of college students and another group of older adults to determine whether they would accurately recall which claim was made in an advertisement for a dietary supplement.  Only 26% of subjects correctly remembered which phrase was used, and the percentage who recalled the information ...

SAN ANTONIO (July 24, 2023) — Staying healthy and connected was difficult for everyone during the COVID-19 pandemic, but especially so for homebound older patients and their caregivers. Fortunately, a program developed by the geriatrics and supportive care team of The University of Texas Health Science Center at San Antonio effectively integrated community health workers (promotores de salud in Spanish) into patient outreach to improve health. Thanks to the program, annual visits to older adults with type 2 diabetes, dementia and other health issues in underserved ...

UNIVERSITY PARK, Pa. — There’s a barrier preventing the advent of truly elastic electronic systems, the kind needed for advanced human-machine interfaces, artificial skins, smart health care and more, but a Penn State-led research team may have found a way to stretch around it.  According to principal investigator Cunjiang Yu, who holds is the Dorothy Quiggle Career Development Associate Professor of Engineering Science and Mechanics and of Biomedical Engineering at Penn State, fully elastic electronic systems require flexibility and stretchability in every ...

Water is the world’s most valuable natural resource. Although a human can survive weeks or even months without food, going as little as three days without water could spell the end. The effects of water scarcity aren’t limited to immediate survival situations, however. Recently published research in Psychological Science suggests that cultures from water-scarce environments tend to be more likely than cultures from water-rich areas to value long-term thinking and to scorn short-term indulgence.  “Individuals from historically water-scarce climates tend to be ...

Metastasis occurs when cancer cells acquire the ability to spread and form new tumors in different places in the body, usually by traveling within blood or lymph vessels. Since metastasis is a hallmark of advanced cancer and severely complicates treatment, its early diagnosis is essential. One way to do this is by looking for circulating tumor cells (CTCs) in blood samples. However, CTCs can be very rare, and they might be completely absent in small blood samples despite being present in a patient’s bloodstream. To address this problem, researchers have developed a technique called diffuse in-vivo flow cytometry (DiFC). It involves labeling CTCs with ...

New research led by Adam Dixon, a conservation scientist with the World Wildlife Fund, describes the successful pilot of a novel method to study how well grassland birds are faring on croplands. The study, published in Ecological Applications, looked at 44 pockets of non-crop vegetation in the gaps between crop rows and at the edges of fields on lands under intensive agricultural cultivation in Iowa. The study may serve as a model for monitoring wildlife on working lands more generally, which can include crop fields, cattle ranches, and logged forests. The researchers analyzed satellite imagery data to determine each pocket's area and “texture,” ...

Snacking is becoming increasingly popular, with more than 70% of people reporting they snack at least twice a day. In a new study involving more than 1,000 people, researchers examined whether snacking affects health and if the quality of snack foods matters.   “Our study showed that the quality of snacking is more important than the quantity or frequency of snacking, thus choosing high quality snacks over highly processed snacks is likely beneficial,” said Kate Bermingham, PhD, a postdoctoral fellow at King's College London. “Timing is also important, with late night snacking being unfavorable for health.”   Bermingham ...

We trust our doctors with our lives, but the sad and scary fact is that doctors can get things wrong. Approximately 100,000 Americans die each year due to medical errors and recent studies have found that 10 to 15% of all clinical decisions regarding patient diagnosis and treatment are wrong. A team of researchers led by Damon Centola, Professor and Director of the Network Dynamics Group at the Annenberg School for Communication at the University of Pennsylvania, has found a simple, effective way to reduce errors in patient diagnosis and treatment — use structured networks to connect clinicians with other clinicians. In a study published today in the journal ...

A surprising finding from USC reveals key details about how cancer cells metastasize and suggests new therapeutic approaches for halting their spread. The research, supported by the National Institutes of Health, centers on a cellular chaperone protein known as GRP78, which helps regulate the folding of other proteins inside cells. Previous studies from the same team, led by Amy S. Lee, PhD, professor of biochemistry and molecular medicine at the Keck School of Medicine of USC, have shown that when cells are under stress (due to COVID-19 or cancer), GRP78 gets hijacked, allowing viral invaders to replicate, ...

The study by Maarten van Herpen et al., entitled “Photocatalytic Chlorine Atom Production on Mineral Dust-Sea Spray Aerosols over North Atlantic,” was funded in part by the NGO Spark Climate Solutions. It incorporates a proposed new mechanism whereby blowing mineral dust mixes with sea-spray to form Mineral Dust-Sea Spray Aerosol (MDSA). The results suggest that MDSA is activated by sunlight to produce an abundance of chlorine atoms, which oxidize atmospheric methane and tropospheric ozone via photocatalysis. Largely composed of blowing dust from the Sahara Desert combined with sea salt aerosol from the ocean, MDSA is the dominant source of atmospheric ...

Researchers from the University of Florida and the Seattle Aquarium are exploring 100 meters underwater in the Pacific Northwest this summer to learn more about mysterious ghost sharks, one of the strangest beasts from the depths of the ocean. Using remotely operated underwater vehicles, or ROVs, the scientists searched for nesting grounds of the Pacific spotted ratfish, Hydrolagus colliei, a ghostlike fish that lurks on the ocean floor. “We know very little about these elusive relatives of sharks and even less about their spawning habits and embryonic development,” said ...

Research Highlights: An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults. The greatest increase in the risk of death from heart attack was seen on days that had the combination of extreme heat and high levels of PM2.5. The days with extreme heat were associated ...
