Creating molecular microrobots that mimic the abilities of living organisms is a dream of nanotechnology, as illustrated by the renowned physicist Richard Feynman. There are a number of challenges in achieving this goal. One of the most significant of these is the creation of directed self-propulsion in water.
Malaria is one of the most dangerous infectious diseases. The causative pathogens are microorganisms of the genus Plasmodium. A particularly dangerous form of the disease is caused by Plasmodium falciparum. Artemisinin is one of the most important antimalarial drugs against this parasite. However, in a mutant of the pathogen that is now spreading, the effect of artemisinin is limited. A team of re

An analysis of all 50 states' school COVID-19 policies finds widespread discordance and variation. The look at policies about masking in schools, requiring COVID-19 vaccines for eligible students and teachers, and providing COVID-19 services in the school setting, finds variation among states but also within states, as individual districts adopt policies at odds with their own governors' guidelin
The increased use of optical fiber has seen a greater focus on the precise control and measurement of its diameter. That is due to the diameter being vital for a wide range of fields, from high-speed optical communication to ultra-high sensitivity sensing. Handling optical fiber before measurement can damage the fiber permanently, particularly when multiple-point measurements are needed.
Smiling makes you look older, according to research by neuroscientists at Western and Ben-Gurion University in Israel. But if you're already over 60, smiling doesn't appear to change the way your age is perceived.
People strongly favor a fairer and more sustainable way of life in the wake of the COVID-19 pandemic, despite not thinking it will actually materialize or that others share the same progressive wishes, according to new research which sheds intriguing light on what people have missed most and want for the future.
Imagine going to hear your favorite orchestral piece played in a world-class venue—and only the woodwind and brass sections turning up. Whether we're aware of it or not, this sparse soundscape is similar to what we're often experiencing when we head out to our favorite parks or nature reserves. The sounds produced by the natural world are changing, which means that the benefits we gain from being
Researchers at Ruhr-Universität Bochum (RUB) have studied how different drugs affect the difficult-to-treat bacterium Pseudomonas aeruginosa. According to the World Health Organisation, new treatment options for the pathogen are urgently required, as some strains are already resistant to all currently approved antibiotics. The Bochum-based team headed by Professor Julia Bandow exposed P. aeruginos
Mars landing missions only succeed about half the time, a rate largely determined by the entry, descent and landing (EDL) phase, according to the researchers who designed Tianwen-1's control systems. They published their guidance, navigation and control approach for Tianwen-1 on October 16 in Space: Science & Technology.
Running water and indoor plumbing are so central to modern life that most Americans take them from granted. But these services aren't free, and millions struggle to afford them. A 2019 survey found that U.S. households in the bottom fifth of the economy spent 12.4% of their disposable income on water and sewer services. News reports suggest that for low-income households, this burden has increased
Snow monkeys living in one of the world's coldest regions survive by 'going fishing' – scooping live animals, including brown trout, out of Japanese rivers and eating them to stay alive, a new study reveals.
It's an old needlework trick, and a protein in our body knows it: Instead of threading yarn into the eye from the end, it can be easier to pass a loop through it. This is how a protein in our body works, unfolding or separating other protein structures. Biologists from the University of Duisburg-Essen (UDE) have made this discovery and published it in Nature Structural & Molecular Biology.
Researchers from North Carolina State University have conducted an in-depth study to establish all of the actions apparel factories will need to take in order to come into compliance with international labor standards.

Sea-level rise is one of the most immediate consequences of climate change, as highlighted recently through urgent pleas from leaders of island nations at the COP26 summit. Global measures of sea-level rise are imperative to underpinning global policy and for strategies to protect coastlines and low-lying lands. Measuring tiny differences in the height of the sea surface from space is no easy task
On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a 'vomit comet' flight, where the plane repeatedly climbs to 8km in a steep parabola, alternating with a descent in freefall. During freefall, at a rate of over 3.3km in 20 seconds, only gravity but no lift, thrust, or drag work on the plane, resulting in weightlessness. The sc

Researchers at the Department of Energy's Oak Ridge, Brookhaven and Idaho national laboratories and Stony Brook University have developed a novel approach to gain fundamental insights into molten salts, a heat transfer medium important to advanced energy technologies.
Geologists describe the process of an earthquake as occurring in three distinct phases. During the interseismic phase, strain builds up along a fault as adjacent pieces of crust catch onto one another and move in opposite directions. This strain eventually reaches a breaking point, initiating the coseismic phase, in which the crust gives way and "snaps" to a new position. This snap is what we expe

A group of Dutch scientists has used space instrument TROPOMI to calculate methane emissions from six Australian coal mines. Together, these account for 7 percent of the national coal production, but turn out to emit around 55 percent of what Australia reports for their total coal mining methane emissions.
There are many things that a vintner can control—where to establish a vineyard, which varieties to plant, when to apply water and fertilizer. But the weather is not one of them. Earlier this year, EUR 2bn worth of wine was lost from French vineyards alone, following a period of extreme cold weather.
From droughts to heatwaves, climate change is putting Europe's cultural heritage and historic urban centers more and more at risk. If damaged, these valuable assets lose their historic value because they cannot be rebuilt. According to the European Commission, natural heritage sites cover about 18 percent of the EU's land.
When I was a child I went to school in South Africa. This was the late 1970s. At school, the teachers would hit us. It was called getting the cane, the cane being a long, flexible stick. This tradition, exported from a Dickensian Victorian English model, was very popular with some teachers. They were seen as terrors: you didn't want to get the cane from them. There was one teacher in particular wh
Climate change with its extreme temperatures and fluctuating precipitations is affecting agricultural land conditions and crop yields.
