Machine learning (ML) programs computers to learn the way we do—through the continual assessment of data and identification of patterns based on past outcomes. ML can quickly pick out trends in big da...
Today, almost the whole accelerator complex is operational and providing beams to all the experimental facilities as scheduled. The LHC experiments are taking data, while the LHC is nearing the end of...
When a star swallows a planet, does it belch? Leave crumbs? Get bigger? No one could say for sure because no one had witnessed it — until now.
The town of Link?ping, Sweden, has a small fleet of autonomous electric buses that carry riders along a predetermined route. The bright vehicles, emblazoned with the tagline, “Ride the Future,” have o...
The subject of Diophantine approximation studies how a real vector is approximated by rational vectors. Diophantine sets are subsets of real vectors defined by certain approximate functions. Among the...
During the last few years, CRISPR has grabbed headlines for helping treat patients with conditions as varied as blindness and sickle cell disease. However, long before humans co-opted CRISPR to fight ...
Keto is Not as Healthy as You Think     Nutrition  Keto  Health       2024/12/19
The Keto diet was rated one of the worst diets for 2022. It promotes heart disease through it’s a high fat intake, creates mineral and vitamin deficiency from the extreme restriction of fruits and veg...
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geop...
Bright reflections observed at Mars’ south pole serve as evidence for water. But, seeing may be deceiving.
The Millennium Drought (southeastern Australia) provided a natural experiment to challenge the assumption that watershed streamflow always recovers from drought.
A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, a...
New research from Martin's lab, in collaboration with the Goddard Space Flight Center, California Institute of Technology and Dalhousie University in Nova Scotia, mapped PM2.5 levels across China, Eur...
Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The evaluation of the sources during a measuring ...
人造板行业离不开胶粘剂。在现代合成树脂创制出来之前多年,就有天然铬蛋白和其他蛋白质制成的胶粘剂用于木质人造板生产。迄今,不断有研究人员谋求回归自然,用生物基单体研制代替合成树脂的新产品。这个想法是很诱人的。生物基树脂的原料是可再生的,而且可利用林产工业的副产品,例如就用本行业的树皮削片,会成为森林价值链的潜在推动力,生物基树脂可比合成树脂更为生态友好,一些生物基树脂可减少甲醛释放。
2021年3月16日,浙江大学生命科学研究院范衡宇课题组在Advanced Science杂志上在线发表了题为“The CNOT4 Subunit of the CCR4-NOT Complex is Involved in mRNA Degradation, Efficient DNA Damage Repair, and XY Chromosome Crossover during Male ...
