Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found. Published today in Scientific Reports, the study draws on data from 30 years of global satellite and model studies to investigate whether changes in ocean wave conditions will have an impact on the stability of coastal environments. The compounding effect of climate change driven variations in waves, storm surge and sea level rise is projected to lead to shoreline position change along most of the world’s sandy coasts. A team ...

The “warm Arctic–cold Eurasia” is one of the most significant patterns of winter climate system changes in the mid-high latitudes of the Northern Hemisphere. In winter 2020/21, this large-scale pattern underwent a significant and intense subseasonal reversal between the early and late winter. At the same time, the sea-ice anomalies in the Barents–Kara Sea changed from being significantly negative in early winter to positive in late winter. For the slow-varying process of winter sea ice, the rapid freezing ...

An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch. Complete plant fossils are seldom found as a single piece, as wood, leaves, flowers, fruits, seeds, or pollen detach easily from plants. This results in leaves and trunks having separate scientific names. Putting together the different parts to reveal the complete plant is like putting together a jigsaw puzzle. Connecting these dots and reconstructing plants is important to establish their taxonomic identity—their ...

A better way to wirelessly charge over long distances has been developed at Aalto University. Engineers have optimized the way antennas transmitting and receiving power interact with each other, making use of the phenomenon of “radiation suppression”. The result is a better theoretical understanding of wireless power transfer compared to the conventional inductive approach, a significant advancement in the field. Charging over short distances, such as through induction pads, uses magnetic near fields to transfer power with high efficiency, but at longer distances the efficiency dramatically drops. New research shows that this high efficiency ...

Highlights: Toxic shock syndrome (TSS) is a rapid-onset, life-threatening disease associated with strains of Staphylococcus aureus. New findings published in Microbiology Spectrum suggest that a probiotic combination could reduce incidence of TSS. In lab experiments, the probiotics reduced production of the superantigen that causes TSS. The researchers say a probiotic approach may also help people who suffer from other staph infections, including those with atopic dermatitis or type 2 diabetes. Washington, D.C. – The widespread, pathogenic microbe Staphylococcus aureus can colonize the skin and mucous membranes throughout the body, particularly the vagina ...

ROCKVILLE, Md.—Researchers have discovered a link between gastric bypass surgery and an increased risk of non-alcohol substance use disorder, according to a new study in Obesity, The Obesity Society’s (TOS) flagship journal. “The current study shows that non-alcohol substance use disorder was 2.5 times more common after gastric bypass surgery compared with controls receiving usual obesity care, but the total number of patients having non-alcohol substance use disorder was overall low. Healthcare professionals should consider the risk of non-alcohol substance use disorder in the care of patients treated with gastric bypass surgery,” ...

Tourists acting as citizen scientists have helped a research team detect microplastics on remote Arctic beaches. The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. But our knowledge of the scale and type of plastic pollution in the Arctic is incomplete. Researchers recruited holidaymakers to carry out sample collection during cruises, hoping to fill in some of the gaps in their knowledge. “Plastic pollution is now ubiquitous. It is found on land and in ...

(Santa Barbara, Calif.) — One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals may be familiar to you; these are the type of molecules we take antioxidant supplements for, in an effort to tame oxidative stress. In the world of synthetic chemistry, however, free radicals hold a lot of promise. “Free radical chemistry is very useful for the synthesis of both bioactive small molecules and everyday polymers,” said UC Santa Barbara chemistry professor Yang Yang, an author of a paper on the matter that appears in Nature Catalysis. “However, ...

Key takeaways A UCLA-led study has shown that hardship experienced by mothers during their own childhood or during pregnancy is reflected in the composition of their 2-year-old children’s gut microbiome. It was previously understood that in rodents, prenatal stress affects microbiomes into adulthood, but how long after birth the effects lasted in humans was unknown. The changes to this community of microorganisms are likely among the ways that hardship affects a child’s socioemotional development. Hardship experienced by mothers during their own childhood or during pregnancy is reflected ...
