COVID-19 Warning: Humid Air Can Extend Lifetime of Virus-Laden Aerosol Droplets
Scientists report a detailed model of aerosol transport through air, considering several environmental conditions, such as temperature, humidity and ambient flow. The novel coronavirus that causes COVID-19 is thought to spread through natural respiratory activities, such as breathing, talking, and coughing, but little is known about how the virus is transported through the air.

Arctic sea ice melting faster than forecast
COPENHAGEN, DENMARK -- The Arctic sea ice is melting faster than climate models had predicted, researchers at the University of Copenhagen warned on Tuesday. Their findings, published in the journal Nature at the end of July, showed the unusually high temperatures currently being seen in the Arctic Ocean have only been observed during the previous ice age.

Army, Texas A&M develop 'Terminator'-style material that can 'heal itself'
U.S. Army and Texas A&M researchers have developed a material that they say can “heal autonomously. ” The research, which is still in the discovery phase, is published in the peer-reviewed journal Advanced Functional Materials. Army researchers, for example, are eyeing drones that can change shape in midflight.

For The First Time, Physicists Have Controlled The Interaction of Time Crystals
The existence of time crystals - a particularly fascinating state of matter - was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals.

Ariane 5 Rocket Launches 3 Spacecraft Into Orbit From Europe’s Spaceport in French Guiana
Europe’s Ariane 5 has delivered two telecom satellites Galaxy-30 and BSAT-4B, and the Mission Extension Vehicle (MEV-2), into their planned transfer orbits. Galaxy-30, with a launch mass of 3298 kg, was the first to be released after about 27 minutes. Galaxy-30 is owned by Intelsat and will deliver high-performance broadcast distribution capabilities, including ultra-high definition and over-the-top streaming media, while also supporting broadband, mobility and enterprise network solutions.

Massive lava tubes on Mars and the moon could be home to life, researchers find
Lava tubes under the surface of both the moon and Mars are large enough to be the homes of planetary bases as humanity further explores the cosmos, a newly published study suggests. The research notes the tubes are likely between 100 and 1,000 times the size of those on Earth and can shield humans from cosmic radiation.

Math Riddle From the 1980’s Finally Solved – Could Be Used to Improve Phones and Computers
Researchers thought that they were five years away from solving a math riddle from the 1980’s. In reality, and without knowing, they had nearly cracked the problem already. “ We had nearly given up on getting the last piece and solving the riddle. We thought we had a minor result, one that was interesting, but in no way solved the problem.

This is when and how the universe is expected to end
It’s not expected to happen anytime soon, but one scientist has calculated when the universe will end. The research, published in the journal Monthly Notices of the Royal Astronomical Society, notes that sometime over the “next few trillion years,” when the universe is dead as we know it, stars will continue to explode, not with a giant bang, but “very, very slowly fizzle. ”

How fast is SpaceX's satellite internet? Beta tests show it hitting up to 60Mbps.
PCMag.com is a leading authority on technology, delivering Labs-based, independent reviews of the latest products and services. Still, many users in the Starlink forum on Reddit are pointing out even a 15Mbps download speed would be a significant improvement over the broadband they currently use. As for whether the speed tests are real, Ookla told PCMag: "These tests do appear to be legitimate.

Scientists identify the ancient enzyme that makes body odor so strong
The same team that identified the handful of bacteria responsible for human body odor has now gone a step further and pinpointed the enzyme operating within those organisms. "This is a key advancement in understanding how body odour works, and will enable the development of targeted inhibitors that stop BO production at source without disrupting the armpit microbiome," said University of York researcher Dr. Michelle Rudden, in a release.

SpaceX’s Starlink satellites ruin another awesome photo
A horde of SpaceX Starlink satellites obscured the view of the comet nicknamed NEOWISE, ruining an otherwise awesome photo of the comet. The satellites reflect light back to Earth, making it difficult for astronomers using high-powered telescopes or cameras to capture clean images of space. Unfortunately, we also see the reflections of countless SpaceX Starlink satellites that happened to be cruising by at the worst possible moment.

Coronavirus lockdown has brought Earth’s vibrations to a halt
“This quiet period is likely the longest and largest dampening of human-caused seismic noise since we started monitoring the Earth in detail using vast monitoring networks of seismometers,” said seismologist Stephen Hicks, from Imperial College London in the UK. “The lockdowns caused by the coronavirus pandemic may have given us a glimmer of insight into how human and natural noise interact within the Earth,” Hicks said.

China’s Mars mission
China has successfully launched its first major interplanetary mission to Mars. The launch begins a long seven-month journey through deep space, and once the mission reaches the Red Planet, China could become just the second nation ever to land and operate a rover on the Martian surface. Called Tianwen-1, China’s mission consists of a Martian orbiter, lander, and rover. The spacecraft should reach Mars in February 2021

New study examines recursive thinking
"The ability to represent recursive structures is present in children as young as three years old, which suggests it is there even before they use it in language," said Stephen Ferrigno, a post-doctoral fellow at Harvard University and first author on the paper.

You can go on a space walk in 2023
The tourist paying to undertake the space walk will fly to the ISS on a Soyuz capsule - the same spacecraft used to ferry NASA astronauts and eight other paying passengers to the station. Until the SpaceX Crew Dragon capsule became the first commercial company to take astronauts to the ISS in May, NASA was paying Roscosmos $80 million a trip to send its crew up to the station.

NASA inviting public to navigate its rovers around Mars
NASA has an algorithm called SPOC (Soil Property and Object Classification), which labels different types of Mars terrain such as boulders or sand to create maps that the rover driver can use when maneuvering the vehicles.
To help with the task of training the algorithm, NASA is inviting the public to help classify bits of martian terrain.
