- ScienceDaily
- 20/9/29 23:34
Scientists have made a leap forward in our understanding of how COVID-19 infections trigger deadly levels of lung inflammation. Their discovery of a pathway that sets the lungs ablaze with inflammation has launched a search for new therapeutics that could block this process before it can take off and turn fatal.
New fire containment research addresses risk and safety
As 2020 has shown, wildfire frequency, size and severity is threatening communities and natural resources across the western U.S. As a result, there is a high demand for decision-making to mitigate risk, improve firefighter safety and increase fire containment efficiency.
California wine country faces long battle as fire explodes
Two California wildfires that ravaged Napa's famous wine region and killed three people exploded in size Tuesday as firefighters faced a weeks-long battle to contain the blazes.
What's the matter with the Universe? Scientists have the answer
A team of US astrophysicists has produced one of the most precise measurements ever made of the total amount of matter in the Universe, a longtime mystery of the cosmos.
Moderna COVID-19 vaccine appears safe, shows signs of working in older adults: study
Results from an early safety study of Moderna Inc's coronavirus vaccine candidate in older adults showed that it produced virus-neutralizing antibodies at levels similar to those seen in younger adults, with side effects roughly on par with high-dose flu shots, researchers said on Tuesday. The study, published in the New England Journal of Medicine, offers a more complete picture of the...
'I'll sleep when I'm dead': The sleep-deprived masculinity stereotype
In the United States, the average American sleeps less than the minimum seven hours of sleep per night recommended by the Center for Disease Control, and nearly half of Americans report negative consequences from insufficient sleep. This problem appears to be especially prevalent in men, who report getting significantly less sleep, on average, than women.
Researchers use membranes that remove salt from water to help 'split' sea water into fuel
The power of the sun, wind and sea may soon combine to produce clean-burning hydrogen fuel, according to a team of Penn State researchers. The team integrated water purification technology into a new proof-of-concept design for a sea water electrolyzer, which uses an electric current to split apart the hydrogen and oxygen in water molecules.
After measuring radiation on the moon for the first time, scientists say a lunar base should be built underground to protect astronauts
Astronauts didn't measure how much radiation they were exposed on the moon. New data show the doses are 200 times higher than on...
World Bank announces $12bn plan for poor countries to buy Covid vaccines
Initiative aims to ensure low-income countries are not frozen out by rich nationsCoronavirus – latest updatesSee all our coronavirus coverageThe World Bank has announced plans for a $12bn (£9.3bn) initiative that will allow poor countries to purchase Covid-19 vaccines to treat up to 2 billion people as soon as effective drugs become available.In an attempt to ensure that low-income countries...
Zimbabwe: Elephants die from 'bacterial disease'
More than 30 elephants were found lying on their stomachs, according to wildlife officials.
Microcomb-injected, pulsed lasers as variable microwave gears
Low-noise microwave signals are of critical importance in numerous applications such as high-speed telecommunication and ultrafast data processing. Conventionally, such signals are generated with bulky and delicate microwave oscillators that are not suitable for out-of-door applications. But recently, physicists have been exploring a possible alternative: high-quality microwave generation using...
Nutritious millet crop could be genetically improved for large-scale agriculture
A nutritious millet crop grown mainly in West Africa could be genetically improved for large-scale agriculture in Saudi Arabia.
Students used their mobile phones for over 8 hours a day during lockdown
A recent study published by researchers from the University of Seville shows that university students make excessive use of their mobile phones. The study relates the number of hours that young people spend sitting down, their level of physical activity and state of mind when using a mobile phone. Students with lower levels of physical activity used their mobile phones almost three times more than...
Genomes of two millipede species shed light on their evolution, development and physiology

Can't stop checking social media for the latest COVID-19 health information? You might want to take a break, according to researchers who discovered that excessive use of social media for COVID-19 health information is related to both depression and secondary trauma.
Using drones to better predict urban flooding
The University of Luxembourg and the start-up RSS-Hydro are working together to optimize the prediction of flooding in Burange in the south of Luxembourg. Supported by the City of Dudelange, the project aims at building a unique and precise urban terrain model with the help of drones, aerial and satellite images to feed state-of-the art flood models.
New research provides clues on optimizing cell defenses when viruses attack
- ScienceDaily
- 20/9/29 21:21
Researchers studying interferons, immune response proteins released naturally by human cells when viruses are detected, have uncovered new details on the mechanisms underlying cell defenses. They describe the intricate, time-dependent regulatory mechanisms that human cells use to control the duration and strength of antiviral responses triggered by interferon. Based on these findings, researchers...
Shifts in butterfly mating preferences
In their efforts to identify the genetic basis for differences in mate choice that keep two co-existing species of butterfly separate, evolutionary biologists at LMU have identified five candidate genes that are associated with divergence in visual mating preferences.
Facultative epiphytes exploit nutrients of rock outcrops and host barks in karst forest
Facultative epiphytes can use different substrates simultaneously, such as trees, rocks, or soil. They are ecotypes of the same species present on different substrates.
Applying human-centered design to voting places
As the United States prepares for November's general election, almost every step of the voting process is being revamped and reevaluated to ensure that COVID-19 will not spread in local communities when millions of Americans cast their ballot in the fall.
Battling harmful insects by understanding their sense of smell
In NTNU's Dragvoll laboratory in Trondheim, researchers keep different things in the closet than most of us do. Jars of moths stand in rows. The insects are actually pretty cute, but the Norwegian name for them suggests that they may be a little annoying: "Pest phage fly" is not exactly a name you give to a friend.
'Blue Planet II' may not have caused a change in plastic preference
The BBC documentary "Blue Planet II" raised environmental awareness, but may not have discouraged people from choosing plastic, says new research.
