NASA-NOAA satellite finds Hurricane Delta rapidly intensifying
Infrared imagery from NASA-NOAA's Suomi NPP satellite revealed that Hurricane Delta has been rapidly growing stronger and more powerful. Infrared imagery revealed that powerful thunderstorms circled the eye of the hurricane and southern quadrant as it moved through the Caribbean Sea on Oct. 6.
Diamonds found with gold in Canada's Far North offer clues to Earth's early history
The presence of diamonds in an outcrop atop an unrealized gold deposit in Canada's Far North mirrors the association found above the world's richest gold mine, according to University of Alberta research that fills in blanks about the thermal conditions of Earth's crust three billion years ago.
Sir Roger Penrose: The man who proved black holes weren't 'impossible'
The UK scientist confessed to being a bit slow in class, but went on to win the Physics...
Evolution of the Y chromosome in great apes deciphered
New analysis of the DNA sequence of the male-specific Y chromosomes from all living species of the great ape family helps to clarify our understanding of how this enigmatic chromosome evolved. A clearer picture of the evolution of the Y chromosome is important for studying male fertility in humans as well as our understanding of reproduction patterns and the ability to track male lineages in the...
UK to buy 1m antibody home tests despite accuracy concerns
Scientists question purchase of tests from British consortium before evaluation made publicThe Department of Health has announced it is buying 1m home antibody tests from a British consortium, even though experts say the only data published about them raises major questions about their accuracy.The government is spending millions of pounds on the tests, made by the UK Rapid Test Consortium. The...
Revising climate models with new aerosol field data
Smoke from the many wildfires burning in the West have made air quality hazardous for millions of people in the United States. And it is the very tiniest of the aerosol particles in that air that make it particularly harmful to human health. But for decades, we haven't known how long these particles actually stay aloft.
Experiments with twisted 2-D materials catch electrons behaving collectively
Scientists can have ambitious goals: Curing disease, exploring distant worlds, clean-energy revolutions. In physics and materials research, some of these ambitious goals are to make ordinary-sounding objects with extraordinary properties: Wires that can transport power without any energy loss, or quantum computers that can perform complex calculations that today's computers cannot achieve. And the...
New climate model helps researchers better predict water needs
New research from the FAMU-FSU College of Engineering combines climate and land use projections to predict water availability, information that is crucial for the preparations of resource managers and land-use planners.
Evidence of Alzheimer's, Parkinson's and MND in brains of young people exposed to dirty air

After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, found markers not only of Alzheimer's disease, but also of Parkinson's and of motor neuron disease (MND) too. These markers of disease were coupled with the presence of tiny, distinctive nanoparticles within the brainstem - their appearance and composition indicating they were...
Study offers global review of impact of COVID-19 on cancer treatment and research

Donors more likely to give to COVID causes when font matches message
- ScienceDaily
- 20/10/6 21:35
Appeals seeking donations to help fight hunger during the COVID-19 pandemic were more successful when the typeface in which the appeal was written mirrored the tone of the donation request, a new study has found.
A simple enrollment change yields big dividends in children's early learning program

Researchers know that texting programs can greatly benefit young children's literacy. Now new research shows that parents' participation in such programs can be boosted exponentially with one simple tweak: automatic enrollment, combined with the ability to opt out.
Pesticides and food scarcity dramatically reduce wild bee population
- ScienceDaily
- 20/10/6 21:35
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring.
Hospitalized COVID-19 patients are younger, healthier than influenza patients, study finds

Patients hospitalized with COVID-19 were more often male, younger, and had fewer underlying medical conditions than hospitalized influenza patients, a new study found.
Underwater robots to autonomously dock mid-mission to recharge and transfer data

- 20/10/6 21:35
Robots exploring deep bodies of water can only go so far before needing to recharge and upload data. Purdue University engineers have designed a mobile docking station system that would help them go farther.
Experiments with twisted 2D materials catch electrons behaving collectively

A team reports that carefully constructed stacks of graphene -- a 2D form of carbon -- can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.
Remote control of blood sugar: Electromagnetic fields treat diabetes in animal models
- ScienceDaily
- 20/10/6 21:35
Researchers may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes blood sugar and insulin resistance. The unexpected and surprising discovery raises the possibility of using electromagnetic fields (EMFs) as a remote control to manage type 2 diabetes.

Are Astronaut-Style Face Shields the Future of PPE?
"If you have to sneeze, you're in trouble," Bill Johnson said of wearing the Air, an acrylic visor that evokes 1960s Soviet cosmonaut culture. Johnson, 44, a voice and video engineer in Utah, had tested an early model of the device on an airplane from Salt Lake City to Seattle to Ketchikan, Alaska, then on a three-hour ferry ride and a floatplane to reach his bush cabin."I flew...
