One nanotube could be great for electronics applications, but there's new evidence that two could be tops.
Bosons and fermions, the two classes into which all particles—from the sub-atomic to atoms themselves—can be sorted, behave very differently under most circumstances. While identical bosons like to congregate, identical fermions tend to be antisocial. However, in one dimension—imagine particles that can only move on a line—bosons can become as stand-offish as fermions, so that no two...
Air pollution from nitrogen dioxide has fallen by an estimated 40 per cent in three European cities, according to new satellite data released by the European Space Agency (ESA), coinciding with a widespread lockdown to curb the spread of the...
NASA has tapped a type of SpaceX cargo craft that hasn't yet been built to deliver supplies to a moon-orbiting outpost that hasn't yet been launched. SpaceX's robotic Dragon XL, a cylindrical, supersized version of its workhorse Dragon spacecraft, will handle shipments to the Gateway space platform as the first commercial provider to receive a Gateway Logistics Services contract from...
Using a newly developed laboratory model of three types of brain cells, scientists reveal how HIV infection -- as well as the drugs that treat it -- can take a toll on the central nervous system.

Theorists find that flexoelectric effects in double-walled carbon nanotubes could be highly useful for photovoltaic applications.
When a one-dimensional gas of strongly interacting bosons expands, the velocity distribution of the bosons transforms into one that is identical to non-interacting fermions.
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land...
Digital manufacturers are stepping in to crank out nasal swabs, ventilator parts, and more as critical supply chains fail.
From lending a hand to local charities to bolstering the efforts of the NHS, there are many ways to get involvedAll our coronavirus coverageI want to help. Where can I find about about volunteering?There are plenty of ways to get involved. Many local charities will be keen to attract new volunteers – especially as older stalwarts are forced to stay at home. Or there are national schemes, such as...

Researchers have developed a triad of innovative tools to engineer low-pH-tolerant yeast Issatchenkia orientalis for production of valuable bioproducts from renewable biomass.
Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn't fully understand why. Existing research from the University of Illinois shows copper doesn't change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs' ability to utilize fat after absorption, resulting in increased energy utilization of...
Scientists have developed a way of extracting a richer palette of colours from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black.
In a study published online yesterday focused on the medical products industry—which includes medical devices, pharmaceuticals and biologics—a group of researchers found that, compared to firms with all-male boards, firms with female directors announced high-severity product recalls 28 days sooner. This is a 35% reduction in the time between when a firm was first made aware of the defect and...

Scientists have developed a new computer simulation model that includes microbubble nucleation to explain the flow slippage of fluids inside pipes. This work may help improve the flow rate of viscous fluids in commercial applications, as in the energy industry.
Even if fatality rates are at the lower end of expectations -- one percent of virus victims -- it is highly likely that death and bereavement services will be overwhelmed.

Researchers have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility -- the ability to adapt to changing situations.
Working in the Arctic Fram Strait, scientists have found microplastic throughout the water column with particularly high concentrations at the ocean floor.
Researchers at the Institute of Industrial Science, The University of Tokyo, used a sophisticated physical model to simulate the behavior of fluids moving through pipes. By including the possibility of shear-induced bubble formation, they find that, contrary to the assumptions of many previous works, fluids can experience significant slippage when in contact with fixed boundaries. This research...
An international research team led by scientists from City University of Hong Kong (CityU) has recently discovered that high-entropy alloys (HEAs) exhibit exceptional mechanical properties at ultra-low temperatures due to the coexistence of multiple deformation mechanisms. Their discovery may hold the key to designing new structural materials for applications at low temperatures.
The US president has been exposed by the coronavirus crisis. The only small comfort for the rest of the world is that he’s not their leaderPity the people of America. They do battle now with one of the greatest challenges in their history, led by a man who is not only among the worst ever occupants of the White House but whose character makes him the last person on the face of the Earth you...
The field is in disagreement about where it should go and why.
There’s a gap in vital data that could help us understand the Covid-19 outbreak, but unfortunately, it’s been misinterpreted and co-opted by policymakers.

A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient. That was written by marine ecologist Jennifer Welsh from NIOZ this week, in a publication in Nature Scientific Reports. This Monday, Welsh will defend her thesis at the Free University of Amsterdam, through an online connection.
A team of scientists at Cardiff University has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest.
With ordinary double-sided tape, researchers in Sweden assembled a chip-based model of a human gut, and then fed it chili peppers to prove it works. The technique could dramatically lower cost barriers for labs that test new drugs and analyze how the body reacts to them.
The Trump administration will temporarily relax civil enforcement of various environmental regulations, a move it says is necessary given worker shortages and travel restrictions related to the coronavirus pandemic.
Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing at the center of the host galaxy. This result will cast light on the mystery of the evolutionary process...
Transfer of mitochondria between cells is a ubiquitously occurring and now universally known phenomenon. For years, researchers have been serially demonstrating that one particular new cell type can transfer its mitos to yet another particular cell type to achieve some specific metabolic goal essential to survival of the meta-host organism. But what happens when the mitochondria come from the...
Making your own ceramics can be a way to express your creativity, but some techniques and materials used in the process could spell bad news for your health and the environment.
