| Exotic quantum particles — less magnetic field required Posted: 15 Dec 2021 08:33 AM PST Researchers have observed exotic fractional states at low magnetic field in twisted bilayer graphene for the first time. |
| Study of Antarctic ice’s deep past shows it could be more vulnerable to warming Posted: 15 Dec 2021 08:33 AM PST Insights into how the West Antarctic Ice Sheet responded to a warmer climate millions of years ago could improve predictions of its future. |
| How a fly's brain calculates its position in space Posted: 15 Dec 2021 08:32 AM PST Neurons in the fly brain appear to literally perform vector math in order to signal the direction in which their bodies are traveling, regardless of which way their heads are pointing. |
| High blood pressure treatment in pregnancy appears safe, prevents maternal heart risks Posted: 15 Dec 2021 05:20 AM PST High blood pressure during pregnancy remains a major cause of maternal and fetal pregnancy-related complications and death, and it increases women's short- and long-term risks for cardiovascular disease. Emerging data from clinical trials and observational research support the benefits and safety of blood pressure treatment during pregnancy. Continued investigation is critical to determine which blood pressure levels, during- and post-pregnancy, both for starting therapy and as treatment goals, are beneficial for the mother and safe and beneficial for the fetus. |
| Meltwater influences ecosystems in the Arctic Ocean Posted: 15 Dec 2021 05:20 AM PST In the summer months, sea ice from the Arctic drifts through Fram Strait into the Atlantic. Thanks to meltwater, a stable layer forms around the drifting ice atop the salty seawater, producing significant effects on biological processes and marine organisms. |
| Biodiversity loss in plants worldwide Posted: 15 Dec 2021 05:20 AM PST Naturalized alien plants are causing a worldwide decline in the uniqueness of regional floras, according to the results of a global research project. |
| Advanced analysis of Apollo sample illuminates Moon’s evolution Posted: 14 Dec 2021 05:05 PM PST Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information about the complex cooling and evolutionary history of the Moon. The diffusion patterns preserved in the mineral grains were consistent with a rapid cooling history of no more than 20-million-years at high temperatures. The finding challenges previous estimates of a 100-million-year cooling duration and supports initial rapid cooling of magmas within the lunar crust. |
| Posted: 14 Dec 2021 05:05 PM PST Despite a lack of evidence that the intrusive IVF treatment process of scratching the womb (endometrial scratching) increases the chances of having a baby, a third of fertility specialists are still offering this often-painful procedure. |
| New guidelines may help reduce tick-borne illness Posted: 14 Dec 2021 10:49 AM PST The number of cases of tick-borne illnesses (TBIs) reported annually to the Centers for Disease Control and Prevention (CDC) has more than doubled over the past two decades in the United States. An expert panel has developed a set of clinical practice guidelines that recommends low-risk interventions, employable with minimal resources, to help reduce the number of TBIs. |
| Decade-old photographs shared on social media give away a new species of pygmy grasshopper Posted: 14 Dec 2021 07:42 AM PST While scrolling the social network iNaturalist, researchers spotted photographs of what turned out to be a Peruvian species of grasshopper currently unknown to science. Having described the new insect with no formal name, the team demonstrates that first, it's not an easy task to describe a species from photographs only, and, secondly, there's a wealth of digital data ready to reveal the Earth's unknown biodiversity. |
| Stress, by itself, can lead to excessive drinking in women but not men Posted: 13 Dec 2021 03:15 PM PST A new study that has important implications for the understanding of sex differences in alcohol consumption has shown that stress alone leads to excessive drinking in women but not men. The study used a simulated bar environment to test how stress affected whether participants drank more than intended. |
| Identifying rare disease-associated genetic variants in patients with severe schizophrenia Posted: 13 Dec 2021 01:01 PM PST New research shows that examining genetic mutations in individuals with severe schizophrenia can improve the ability to detect disease-associated rare genetic variants. |
