A satellite-based dataset generated by KAUST researchers has revealed the dynamics of dust storm formation and movements over the last decade in the Arabian Peninsula. Analysis of this long-term dataset reveals the connection between the occurrence of extreme dust events and regional atmospheric conditions, a finding that could help improve weather forecasting and air-quality models.
Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from Belgium take a step in the development of genome editing technology. Currently it is possible to deliver genetic material of different sizes and structures to organs and tissues. This is the key to eliminating DNA defects and treating more patients.
Semiconducting 2D alloys could be key to overcoming the technical limitations of modern electronics. Although 2D Si-Ge alloys would have interesting properties for this purpose, they were only predicted theoretically. Now, scientists from Japan Advanced Institute of Science and Technology have realized the first experimental demonstration. They have also shown that the Si to Ge ratio can be adjusted to fine tune the electronic properties of the alloys, paving the way for novel applications.
New study found that electrons can reach ultra-relativistic energies for very special conditions in the magnetosphere when space is devoid of plasma.
Cholangiocarcinoma (CCA) is considered as a diverse group of epithelial cancers characterized by poor outcomes. Cholangiocarcinoma can be divided into three types according to the original position: Intrahepatic Cholangiocarcinoma (ICC), Perihilar Cholangiocarcinoma (PCC) and Distal Extrahepatic Tumors (DET). The most promising way to cure cholangiocarcinoma is surgery, including laparoscopic liver resection and open liver resection. However, the post-surgical outcome is less than satisfactory and there is a poor 5-years survival rate of 16.5-48%.
University of Sussex academics have established a method of turbocharging desktop PCs to give them the same capability as supercomputers worth tens of millions of pounds.
Dr James Knight and Prof Thomas Nowotny from the University of Sussex's School of Engineering and Informatics used the latest Graphical Processing Units (GPUs) to give a single desktop PC the capacity to simulate brain models of almost unlimited size.
New research by the University of Kent has found that optical coherence tomography (OCT) imaging technology can be utilised to distinguish between legitimate and counterfeit travel documents.
OCT imaging has been widely used in the medical and biomedical fields, recognised as transforming the field of clinical ophthalmology, and this research published in Science & Justice has now identified its capabilities for forgery detection use.
BOSTON - Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimer's disease, and detecting their buildup at an early stage may allow clinicians to intervene before the condition has a chance to take hold. A team led by investigators at Massachusetts General Hospital (MGH) has now developed an automated method that can identify and track the development of harmful tau deposits in a patient's brain.
Interim analysis from phase 3 trial of nearly 20,000 participants suggests efficacy of two-dose regimen of the adenovirus-based vaccine is 91.6% against symptomatic COVID-19 - trial reports 16 COVID-19 cases in the vaccine group (0.1% [16/14,964) and 62 cases (1.3% [62/4,902]) in the placebo group.
No serious adverse events were deemed to be associated with vaccination, and most reported adverse events were mild, including flu-like symptoms, pain at injection site and weakness or low energy.
The many different sensations our bodies experience are accompanied by deeply complex exchanges of information within the brain, and the feeling of pain is no exception. So far, research has shown how pain intensity can be directly related to specific patterns of oscillation in brain activity, which are altered by the activation and deactivation of the 'interneurons' connecting different regions of the brain. However, it remains unclear how the process is affected by 'inhibitory' interneurons, which prevent chemical messages from passing between these regions.
A soft, flexible sensor system created with electrically conductive yarns could help map problematic pressure points in the socket of an amputee's prosthetic limb, researchers from North Carolina State University report in a new study.
WASHINGTON, February 2, 2021 -- Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors.
Cancer immunotherapy has some remarkable successes, but its effectiveness has been limited to a relatively small handful of cancers. In APL Bioengineering, by AIP Publishing, a team from Stanford University and Genentech describes how advances in engineering models of tumors can greatly expand cancer immunotherapy's effectiveness to a wider range of cancers.
Researchers at the George Washington University and University of California, Los Angeles, have developed and demonstrated for the first time a photonic digital to analog converter without leaving the optical domain. Such novel converters can advance next-generation data processing hardware with high relevance for data centers, 6G networks, artificial intelligence and more.
DeKalb, Ill. -- If you build it, they might not come. That's the key finding of a new study on habitat restoration practices that challenges a commonly accepted principle in ecology.
The mesmerizing flow of a sidewinder moving obliquely across desert sands has captivated biologists for centuries and has been variously studied over the years, but questions remained about how the snakes produce their unique motion. Sidewinders are pit vipers, specifically rattlesnakes, native to the deserts of the southwestern United State and adjacent Mexico.
