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.

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.

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...

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...

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...

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

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.

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.

Understanding the secretive networks used to move money offshore

In 2016, the world's largest ever data leak dubbed "The Panama Papers" exposed a scandal, uncovering a vast global network of people—including celebrities and world leaders, who used offshore tax havens, anonymous transactions through intermediaries and shell corporations to hide their wealth, grow their fortunes and avoid taxes.

NASA's infrared view of typhoon Kujira

NASA's Terra satellite used infrared light to identify strongest storms and coldest cloud top temperatures in Typhoon Kujira as it tracked through the northwestern Pacific Ocean.
