Storms Alpha and Beta named for Greek alphabet, second time ever

Meteorologists were forced to break out the Greek alphabet Friday to name Atlantic storms for only the second time ever after the 2020 hurricane season blew through their usual list, ending on Tropical Storm Wilfred.

The four most promising worlds for alien life in the solar system

The Earth's biosphere contains all the known ingredients necessary for life as we know it. Broadly speaking these are: liquid water, at least one source of energy, and an inventory of biologically useful elements and molecules.

Anti-resonant hollow-core optical fiber reduces 'noise'

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Google testing automatic tab-grouping feature

There are people in this world who are perfectly content to work on their computers with only one or two open browser tabs at a time. But then there are folks who collect a dozen, two dozen or more tabs each session, frantically ...

Immune system may have another job—combatting depression

An inflammatory autoimmune response within the central nervous system similar to one linked to neurodegenerative diseases such as multiple sclerosis (MS) has also been found in the spinal fluid of healthy people, according ...

Indian monsoon can be predicted better after volcanic eruptions

Large volcanic eruptions can help to forecast monsoons over India. This seasonal rainfall is key for the country's agriculture and thus for feeding 1 billion people. As erratic as they are, volcanic eruptions improve the ...

Biologists create new genetic systems to neutralize gene drives

In the past decade, researchers have engineered an array of new tools that control the balance of genetic inheritance. Based on CRISPR technology, such gene drives are poised to move from the laboratory into the wild where ...

Removal of a gene could render lethal poxviruses harmless

The removal of one gene renders poxviruses—a lethal family of viral infections that are known to spread from animals to humans—harmless, a new study in the journal Science Advances reports.

Engineers produce a fisheye lens that's completely flat

To capture panoramic views in a single shot, photographers typically use fisheye lenses—ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images. ...

Efforts afoot to save South's disappearing grasslands

In the early 2000s, a harvest of pine trees on Tennessee's Cumberland Plateau led to a remarkable discovery. Once sunlight hit the ground, the seeds and rootstock of native grasses and wildflowers that had lain dormant for ...

Pulling the plug on the coronavirus copy machine

Key proteins used by coronavirus for its reproduction being modeled on NSF-funded Frontera supercomputer by Andres Cisneros research group of the University of North Texas. Research goals include finding ways to improve on ...

California wildfire smoke blankets parts of Canada

Smoke from California and Oregon wildfires has cloaked Canada's third-largest city of Vancouver—known for its majestic mountain views and fresh ocean breezes—in the dirtiest air in the world this week.

Massive damage of rare plants probed at Nevada mine site

State and federal authorities are investigating the mysterious loss of a significant swath of a rare desert wildflower that's being considered for federal protection at a contentious mine site in Nevada with some of the largest ...

Aqua satellite helps confirm Subtropical Storm Alpha

Subtropical Storm Alpha has formed near the coast of Portugal, becoming the first named storm using the Greek Alphabet list, now that the annual list of names is exhausted. NASA's Aqua satellite obtained visible imagery of ...

Human genetics: A look in the mirror

Who are we? Where did we come from? How did we get here? Throughout the ages, humans have sought answers to these questions, pursuing wisdom through religion, philosophy, and eventually science. Evolutionary analyses published ...

Survey explores impact of technology-facilitated abuse

A team from The University of Queensland, Queensland University of Technology and University College London is examining how domestic and sexual violence survivors are being impacted by Internet of Things (IoT) technology, ...

Measuring air pollution in a post-COVID-19 world

Air pollution is one of the biggest environmental problems of our time. According to a new report from the European Environment Agency (EEA), air pollution now contributes to one in eight deaths in Europe. Observations from ...
