Scientists have completed the largest and most diverse genetic study of type 1 diabetes ever undertaken, identifying new drug targets to treat a condition that affects 1.3 million American adults.
Several potential drugs are already in the pipeline. Drugs targeting 12 genes identified in the diabetes study have been tested or are being tested in clinical trials for autoimmune diseases. That could accelerate the drugs' repurposing for treating or preventing type 1 diabetes, the researchers say.
Scientists have developed a 'nanobody' - a small fragment of a llama antibody - that is capable of chasing out human cytomegalovirus (HCMV) as it hides away from the immune system. This then enables immune cells to seek out and destroy this potentially deadly virus.
The research team of Prof. Xiaobo Ji and associate Prof. Guoqiang Zou has proposed an ingenious oxygen vacancy (OV)-engineering strategy to realize high content anionic doping in TiO2 and offered valuable insights into devise electrode materials with fast charge transfer kinetics in the bulk phase. The article titled "High content anion (S/Se/P) doping assisted by defect engineering with fast charge transfer kinetics for high-performance sodium ion capacitors" is published in Science Bulletin. Xinglan Deng is listed as first author and Prof. Guoqiang Zou as corresponding author.
Not enough progress has been made to address physical inactivity worldwide, with adolescents and people living with disabilities (PLWD) among the least likely populations to have the support needed to meet the World Health Organization (WHO)'s physical activity guidelines. Global efforts to improve physical activity have stalled, with overall deaths caused by physical activity remaining at more than 5 million people per year. 
Two years on from its pledge to make England smoke free by 2030, the UK government has failed to deliver on the policies it promised to deliver this ambition, say a group of leading doctors, professional bodies and charities in The BMJ today.
In an open letter to the Prime Minister and Secretary of State for health, they say smoking is likely to have killed more people last year than covid-19 and it will carry on doing so for many years to come unless the government takes action.
Chestnut Hill, Mass. (7/21/2021) - Researchers have discovered a "layer" Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion insulating state, the team reports in the current edition of the journal Nature.
Scientists at St. Jude Children's Research Hospital have found a link between post-cancer treatment frailty and neurocognitive decline in young adult childhood cancer survivors. A paper on this work was published today in the Journal of Clinical Oncology.
One of the major challenges in modern cancer therapy is the adaptive response of cancer cells to targeted therapies: initially, these therapies are very often effective, then adaptive resistance occurs, allowing the tumor cells to proliferate again. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. The analysis of these mechanisms is limited by the complexity of cause and effect relationships that are extremely difficult to observe in vivo in tumor samples.
Rome (Italy), July 21st, 2021 - The remarkable structural properties of the basket sponge (E. aspergillum) might seem fathoms removed from human-engineered structures. However, insights into how the organism's latticework of holes and ridges influences the hydrodynamics of seawater in its vicinity could lead to advanced designs for buildings, bridges, marine vehicles and aircraft, and anything that must respond safely to forces imposed by the flow of air or water.
At low temperatures, certain materials lose their electrical resistance and conduct electricity without any loss - this phenomenon of superconductivity has been known since 1911, but it is still not fully understood. And that is a pity, because finding a material that would still have superconducting properties even at high temperatures would probably trigger a technological revolution.
Classical molecular sieve membranes, with 3D microparticles and 2D nanosheets as primary building blocks, are promising in chemical separation.
Separation within such membranes relies on molecular movement and transport though their intrinsic or artificial nanopores. Since the weak connections by nature between the neighboring "bricks" usually result in intercrystalline gaps in membranes, the prevailing selectivity for classical molecular sieve membranes is moderate.
Professors at Ural Federal University (UrFU, Russia) Sergey Shcheklein and Aleksey Dubinin have developed a technology for generating energy for an electric car engine using methanol. An article describing the technology was published in the International Journal of Hydrogen Energy.
Carbohydrates have traditionally been the largest source of energy intake for much of the world's population1. However, without a standard definition for carbohydrate quality, some foods that contain carbohydrates are often stigmatized based on isolated and reductionist assessment methods that fail to consider their contributions to nutrient intakes and balanced, healthy diets.
Each year, hundreds of thousands of people worldwide suffer from peripheral nerve injuries, which often leave them with long-term disabilities. The peripheral nervous system is analogous to the circulatory system; a network of vessels that reaches all parts of the body, but instead of blood flowing through vessels, electrical signals propagate information through thin fibers called axons, which are engulfed within nerve trunks.
A far-reaching new study of the life-cycle greenhouse gas (GHG) emissions from passenger cars, including SUVs, draws sharp and meticulous distinctions between the climate impacts of battery and fuel cell electric vehicles on one hand and combustion vehicles on the other.
