A small number of self-organizing autonomous vehicles significantly increases traffic flow
Researchers have developed a suite of algorithms to improve the performance of cyber-physical systems - from autonomous vehicles to smart power grids - by balancing each component's need for data with how fast that data can be sent and received.

How dangerous are burning electric cars?
With the addition of just a small number of autonomous vehicles (AVs) on the road, traffic flow can become faster, greener, and safer in the near future. Researchers present a simple set of guidelines and regulations for achieving the self-organization of AVs into constellations that dynamically control the entire traffic flow even when fewer than 5 percent of the vehicles on the road are...

How to weigh a dinosaur
What happens if an electric car burns in a road tunnel or an underground car park? In the Hagerbach test tunnel in Switzerland, researchers and tunnel safety experts set fire to battery cells of electric cars, analyzed the distribution of soot and smoke gases and the chemical residues in the extinguishing water.

Global heating motivated American mastodons to trek north
Caught in an Atlantic hurricane, satellite-tagged loggerhead turtles changed their dive behavior and movement patterns as the storm passed. The tags also recorded changes in the environment.
Decorating windows for optimal sound transmission
Shift led to local extinctions and could have important implications for species todayGenetic diversity could shrink as animals venture into new territories because of global heating leaving them vulnerable to extinction, scientists have warned after tracking the impact of climate change on the American mastodon.Huge, hairy and with a pair of fearsome tusks, mastodons resembled stocky, hirsute...
Different responses in individual cells give muscles more control
Glass windows typically offer some amount of soundproofing, sometimes unintentionally. In general, ventilation is required to achieve large sound transmission.
Face shields, masks with valves ineffective against COVID-19 spread: study
Minute differences in individual muscle cell contractions allow the entire muscle to flex with greater control and accuracy. Long dismissed as "noise" or error, experts now suspect that biological systems may have evolved to include unavoidable variation as a form of information in their communication channels. A team of experts from the University of Tokyo published these findings in the...
Detecting small amounts of virus in early infections
If the United States Centers for Disease Control and Prevention (CDC) guidelines aren't enough to convince you that face shields alone shouldn't be used to stop the spread of COVID-19, then maybe a new visualization study will.
Mastodons took frequent trips north when climate changed
Diagnostic devices that are used at home or in doctors' offices are often not sensitive enough to detect small amounts of a virus that might be present in samples from asymptomatic patients, which can occur in early stage COVID-19. In Biomicrofluidics,, scientists report a membrane-based invention that can concentrate the virus content of a sample of urine or saliva, allowing it to be detected.
Direct observation of desorption of a melt of long polymer chains
New research suggests that American mastodons were avid travelers, migrating vast distances across North America in response to dramatic climate change during the ice ages of the Pleistocene. The study, conducted by an international team of scientists and published today in the journal Nature Communications, also reveals that mastodon populations that headed northward to the Arctic during warm...
Additive manufacturing of multi-functional parts
In our everyday life it's not uncommon to see the same material in different states. Take for example water: it's a liquid at ambient temperature, we can convert into ice when cooled below 0°C and it becomes a gas when heated above 100°C. The passages between these different states of matter are called phase transitions.
Vanessa Redgrave calls on businesses to help UK's Covid-hit arts sector
Additive manufacturing is currently one of the most significant trends in industry. Now a team from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS has developed a Multi Material Jetting system that allows different materials to be combined into a single additively manufactured part. This makes it possible to create products with combined properties or functions. The new system...
The best of both worlds for economic predictions
Actor appeals for funds to save jobs in industry that is one of worst affected by pandemicCoronavirus – latest updatesSee all our coronavirus coverageVanessa Redgrave has urged businesses and entrepreneurs to give money to help restore Britain’s coronavirus-threatened arts infrastructure.The actor is expected to be joined by Sir Lenny Henry, Maxine Peake and Sir Trevor Nunn on Tuesday evening...
Q&A: Researchers set out to clear the seabed of plastic
Danish physicist Neils Bohr once quipped that prediction is hard, especially when it is about the future. But this is precisely what financial regulators need to do—forecasting the likely state of the economy in the future is crucial when deciding on policy levers like whether to slash or raise interest rates.
How tadpoles provide insight into pandemics
Eighty-six million metric tons of plastics end up in the oceans every year, with devastating consequences for marine life, nature and, ultimately, for us humans. The vast floating patches of plastic carpeting the water's surface, some as large as entire countries, are only the tip of the iceberg. Around 90 percent of this garbage ends up on the seabed. The Fraunhofer Center for Maritime Logistics...
Stable supply of electrochromic metallo-supramolecular polymer
A virus affecting wood frog tadpoles throughout the eastern United States is offering scientists a rare opportunity to investigate the role of environmental factors in the spread of infectious disease.
Surface and Exosphere Alterations by Landers (SEAL): NASA’s Next Lunar Payload?
National Institute for Materials Science (NIMS) and Tokyo Chemical Industry Co., Ltd. (TCI) have jointly developed a synthetic process capable of stably supplying a metallo-supramolecular polymer electrochromic (EC) material. Popularization of this material may stimulate growth in the market for dimming windows capable of electrically changing tint from transparent to dark.
Zoom rides pandemic to another quarter of explosive growth
Surface and Exosphere Alterations by Landers (SEAL)
SEAL will provide valuable in situ lunar data to give scientists insight into how a spacecraft landing might affect the composition of nearby regolith samples.
SEAL engineers and technicians assemble the flight payload in a clean room at GSFC.
When a space vehicle lands on the Moon, it interacts with the lunar surface...
New bacteria and algae process could help decarbonize UK military

New feline vaccination guidelines
A new biological engineering process that could help to decarbonise the UK military is set to be developed by researchers at the University of Sheffield.
Queen of the Dolomites glacier could vanish within 15 years
The American Animal Hospital Association (AAHA) and the American Association of Feline Practitioners (AAFP) convened a panel of experts to update the 2013 AAFP Feline Vaccination Advisory Panel Report. The release of the 2020 AAHA/AAFP Feline Vaccination Guidelines provides updated recommendations and the most current information for feline vaccinations.
Researchers manipulate two bits in one atom
Italian scientists warn Marmolada has shrunk 80% in 70 years due to global heatingThe largest and most symbolic glacier in the Dolomites could vanish within 15 years because of global heating, Italian scientists have warned.The 3,343m Marmolada, located on the border of the Trentino and Veneto regions and known as the Queen of the Dolomites, has already lost more than 80% of its volume over the...
Researchers at Delft University of Technology have succeeded in independently manipulating two different types of magnetism within a single atom. The results are relevant for the development of extremely small forms of data storage. In time, this new discovery could make it possible to store two bits of information in one atom.
