Socioeconomic factors, like education and location, can affect access to life-saving prenatal care services. Researchers at Boston Children’s Hospital are taking steps towards implementing strategies that improve access to prenatal care: estimating how many pregnant people attend the recommended number of visits and identifying pregnant people who are at high risk of failing to attend. This could help policymakers allocate resources to populations not getting enough prenatal care and could, in turn, improve health outcomes for mothers and babies. Led by Grace Chan, M.D., Ph.D., Attending Physician in the Intermediate Care Program at Boston ...

Fish from the same species can evolve their sense of smell and display individual foraging ‘personalities’ to successfully find food in different habitats, according to new research.   In the study, published today as a Reviewed Preprint in eLife, researchers developed a high-throughput behavioural assay to test spontaneous swimming and differences in the sense of smell of individual Mexican cavefish larvae. eLife editors described the work as important, presenting compelling evidence that the surface and cave morphs of the fish show different olfactory preferences and odour sensitivities, and that individual fish show substantial variability in their spontaneous ...

Scientists have identified the protein that helps poison dart frogs safely accumulate their namesake toxins, according to a study published today in eLife. The findings solve a long-standing scientific mystery and may suggest potential therapeutic strategies for treating humans poisoned with similar molecules. Alkaloid compounds, such as caffeine, make coffee, tea and chocolate delicious and pleasant to consume, but can be harmful in large amounts. In humans, the liver can safely metabolise modest ...

Toxic chemicals produced from oil emissions and wildfire smoke have been found in muscle and liver samples from Southern Resident killer whales and Bigg’s killer whales. A study published today in Scientific Reports is the first to find polycyclic aromatic hydrocarbons (PAHs) in orcas off the coast of B.C., as well as in utero transfer of the chemicals from mother to fetus. “Killer whales are iconic in the Pacific Northwest—important culturally, economically, ecologically and more. Because they are able to metabolically process PAHs, these are most likely recent exposures. Orcas are our canary in the coal ...

Wars, drought, displacement, and instability are causing a dramatic increase in the number of pregnant and breastfeeding women around the world who suffer from malnutrition. Without access to sufficient nutrients in the womb, babies born to these women are more likely to die due to complications like pre-term birth, low birth weight, and susceptibility to diseases like malaria. To try to reduce the risk of malarial infection, the WHO recommends that pregnant women in low-income countries be treated with a combination of the antimalarial drugs sulfadoxine and pyrimethamine ...

Heart rates are easier to monitor today than ever before. Thanks to smartwatches that can sense a pulse, all it takes is a quick flip of the wrist to check your heart. But monitoring the cells responsible for heart rate is much more challenging — and it’s encouraged researchers to invent new ways to analyze them. Joseph Wu, M.D., Ph.D., director of the Stanford Cardiovascular Institute and professor of medicine and of radiology, has devised a new stem cell-derived model of heart tissue ...

The Beach Boys’ iconic hit single “Good Vibrations” takes on a whole new layer of meaning thanks to a recent discovery by Rice University scientists and collaborators, who have uncovered a way to destroy cancer cells by using the ability of some molecules to vibrate strongly when stimulated by light. The researchers found that the atoms of a small dye molecule used for medical imaging can vibrate in unison ⎯ forming what is known as a plasmon ⎯ when stimulated by near-infrared light, causing the cell membrane of cancerous cells to rupture. ...

Stroke is an abrupt, devastating disease that instantly changes a person’s life and has the potentially to cause lasting disability or death. However, the condition also has profound effects on the patient’s loved ones — who are often called to make difficult decisions quickly. A new study led by Michigan Medicine finds that nearly 30% of caregivers of severe stroke patients experience high levels of anxiety, depression or post-traumatic stress during the first year after the patient leaves the hospital. The results are published in Neurology. “As physicians, we usually concentrate on our ...

MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. Images   Pandas, long portrayed as solitary creatures, do hang with family and friends — and they’re big users of “social media.” Scent-marking trees serve as a panda version of Facebook. An article in the international journal Ursus paints a new lifestyle picture of the beloved bears in China’s Wolong National Nature Reserve, a life that’s shielded from human eyes because they’re shy, rare and live in densely forested, remote areas. No one really knows how pandas hang, but a new study indicates pandas are around others more than previously thought. ...
