It's the battle of the billionaires. Virgin Galactic CEO Richard Branson managed to one up competitor and Blue Origin CEO Jeff Bezos by getting to "space" nine days before Bezos could even climb on board his own rocket. On Sunday, Branson — alongside a crew of six — successfully managed to reach an altitude of 50 miles after being carried to 50,000 feet inside a rocket plane called VSS Unity, att
A tiny, inflatable implant that can be injected directly into the spinal column could provide long-term relief from chronic pain by emitting electrical charges that signal the brain to stop perceiving it
Astronomers have definitively detected a black hole devouring a neutron star for the first – and second – time. These cataclysmic events created ripples in space-time called gravitational waves that travelled more than 900 million light years to reach detectors on Earth
Covid-19 is a mainly airborne disease. So does our endless disinfecting and hand sanitising serve any purpose – or could it be worse than useless? Claudia, a 26-year-old beauty worker, dreads it when her clients ask to go to the toilet. "It's a whole other thing to clean," she says. "They could have touched anything in there. I have to wipe down the whole thing with antibacterial spray and wipes.
A team of researchers affiliated with multiple institutions in China, working at the University of Science and Technology of China, has achieved another milestone in the development of a usable quantum computer. The group has written a paper describing its latest efforts and have uploaded it to the arXiv preprint server.
In 2015, 170 countries worldwide adopted the Paris Agreement, with the goal limiting the average global temperature increase to 1.5°C. Following the agreement, many countries and cities proposed targets for greenhouse gas mitigation. However, the UNEP Emissions Gap Report 2020 shows that, without drastic and strict actions to mitigate the climate crisis, we are still heading for a temperature incr
Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be a reality. A new type of reflective screen—sometimes described as electronic paper—offers optimal color display, while using ambient light to keep energy consumption to a minimum.
Scientists at Oak Ridge National Laboratory and the University of Wisconsin–Madison have discovered that genetically distinct populations within the same species of fungi can produce unique mixes of secondary metabolites, which are organic compounds with applications in medicine, industry and agriculture.

Tide Pool Starting next decade, scientists say, a "wobble" in the Moon's orbit is about to make coastal flooding here on Earth a whole lot worse. When the wobble begins, American coastal cities may suddenly start to flood three or four times as often as they do now, according to research by NASA and the University of Hawaii that was published in the journal Nature Climate Change last month. In th
Average length of friendship before relationship turns romantic is 22 months, study says When Harry first met Sally, he asserted men and women could not be friends because the "sex part always gets in the way". But new research suggests roughly two-thirds of couples start out as friends and maintain a platonic relationship for long periods before sparking a romance. Continue reading…
F irst comes the piece of timber. Then the strip of leather. Then the fence, the mountain, the trees, the river. The pictures whirl, like icons in a Western-themed slot machine, until they land on their final image: the smiling face of Tucker Carlson. This spring, Carlson began hosting a new show on Fox Nation, the network's digital streaming service. Tucker Carlson Today features interviews, one
T o many Americans, Brad Raffensperger is one of the heroes of the 2020 election. Georgia's secretary of state, who is a conservative Republican, refused then-President Donald Trump's direct pleas to "find" the votes that would overturn his defeat in the state. "I've shown that I'm willing to stand in the gap," Raffensperger told me last week, "and I'll make sure that we have honest elections." A
Nuclear Plant The concept of using nuclear power to build out our human presence in other parts of the solar system is as alive as it's ever been. Case in point, a subsidiary of Russia's Roscosmos space agency is now proposing a nuclear power station on Mars, intended to power a future Russian base on the Red Planet, state-run news agency Sputnik reports . The Arsenal Design Bureau, the subsidiar
All life on Earth rests on the same foundation: a four-letter genetic alphabet spelling out a repertoire of three-letter words that specify 20 amino acids. These basic building blocks — the components of DNA and their molecular interpreters — lie at biology's core. "It's hard to imagine something more fundamental," said Floyd Romesberg, a synthetic biologist at the pharmaceutical company Sanofi.
Lindsey Kaczmarek gets called an ambulance driver more often than she gets called a paramedic. "That's absolutely not what I do," she told me. What she does do is show up when someone needs medical help, figure out what's wrong with them, and do whatever she can to help them survive the trip to the hospital—in her case, the Mayo Clinic in Rochester, Minnesota. The primary symptom for one in three
A former UK chief scientist is planning experiments to drop iron filings in oceans to tackle climate change and restore marine life, in a major geoengineering project that is likely to prove controversial

Through new analysis of samples collected in 2007 and 2013 from dam lakes along the river, Lake Sagami and Lake Tsukui, researchers identified a species of freshwater algae that evolved
Imagine a dust particle in a storm cloud, and you can get an idea of a neutron's insignificance compared to the magnitude of the molecule it inhabits. But just as a dust mote might affect a cloud's track, a neutron can influence the energy of its molecule despite being less than one-millionth its size. And now physicists at MIT and elsewhere have successfully measured a neutron's tiny effect in a
Researchers led by a UMass Lowell environmental science professor say mercury measurements in a Massachusetts forest indicate the toxic element is deposited in forests across the globe in much greater quantities than previously understood.

The study shows that even after the temporary decline wears off, recreational cannabis laws are not associated with increases in opioi
Quarantine proved what we already knew was coming: on-demand delivery is the future of commerce. Jeff Bezos is the world's richest person because he understood that it's much, much more convenient to shop from the comfort of your home than to actually go to a store. Amazon seems to sell virtually everything, but there's one big thing Bezos missed out on: the opportunity to deliver the best alcoho
Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost — tolerating the jarring sounds of commercial airplanes during landing and takeoff. Researchers at Texas A&M University have conducted a computational study that validates using a shape-memory alloy
UC San Diego researchers discovered that immunotoxins targeting the protein mesothelin prevent liver cells from producing collagen, a precursor to fibrosis and cirrhosis, in mouse models of human disease.
Butterflies and moths have beautiful wings: The bright flare of an orange monarch, the vivid stripes of a swallowtail, the luminous green of a Luna moth. But some butterflies flutter on even more dramatic wings: Parts of their wing, or sometimes the entire wing itself, are actually transparent.

The sharp eyes of an eagle, the extraordinary hearing of an owl – to successfully find food, the eyes and ears of birds have adapted optimally to their living conditions. Until now, the sense of smell has played a rather subordinate role. When meadows are freshly mowed, storks often appear there to search for snails and frogs. Researchers have now studied the birds' behavior and discovered that th
You know your dog gets your gist when you point and say 'go find the ball' and he scampers right to it. This knack for understanding human gestures may seem unremarkable, but it's a complex cognitive ability that is rare in the animal kingdom. New research comparing dog puppies to human-reared wolf pups offers some clues to how dogs' unusual people-reading skills came to be.
Many exoplanets have opaque atmospheres, obscured by clouds or hazes that make it hard for astronomers to characterize their chemical compositions. A new study shows that haze particles produced under different conditions have a wide range of properties that can determine how clear or hazy a planet's atmosphere is likely to be.
Ecologists have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-caught, a key piece of evidence required in many cases to determine whether a trade is legal or not. They have applied this technique to the yellow-crested cockatoo, a critically endangered species from Indonesia/Timor-Leste with a global population of fewer than 2,500.
Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions.

The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions.
Researchers have discovered how otters stay warm in frigid temperatures. Sea otters' muscles use enough energy through leak respiration, energy not used to perform tasks, that it accounts for their high metabolic rate, according to a new study. Sea otters are the smallest marine mammal. As cold-water dwellers, staying warm is a top priority, but their dense fur only goes so far. Researchers have
The answers to today's logical conundrums Earlier today I set the following three puzzles, which have all been set during Oxford university admissions interviews for joint philosophy courses. In each case, there is an initial question, which almost all candidates answer correctly. The follow-up questions are more challenging. 1. Stephanie's surprise. Continue reading…
New research digs into the question of how DNA repair works in reproductive cells like sperm and eggs during development. DNA damage occurs dozens or even hundreds of times within each individual developing sperm or egg cell, and the process occurs in organisms ranging from yeast cells to humans. "The DNA repair pathway we studied is effectively perfect, in that it is able to resolve damage with

The COVID-19 pandemic has wrecked lives and wreaked havoc on economies around the world. Part of the problem has been our solution to disease. The measures, such as social, business, and educational lockdown and border controls that are aimed at stopping the spread of the novel coronavirus—SARS-CoV-2, which causes COVID-19—have disrupted the supply of agricultural food products to markets and cons
Astronomers have analyzed light data from a piece of supernova shrapnel—a star called LP 40-365—to gain clues about where it came from. About 2,000 light years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star, known as LP 40-365, is one of a unique breed of fast-moving stars—remnant pieces of massive white dwarf stars—that have survived in chunks
Human Usher syndrome is the most common form of hereditary deaf-blindness. Researchers have now identified a novel pathomechanism leading to Usher syndrome.

There's been a recent push to label those with abnormal neuropsychological behaviors as "neurodiverse" rather than "autistic" or "dyslexic." This is an attempt to both remove the stigma attached to these abnormalities and also to call into question whether there is any such thing as a normal brain. The problem with getting rid of neuropsychological labels, however, is that it risks ignoring those

The result, which even is more useful in realistic black hol
Whether birds can taste sweet was previously unclear. An international team of researchers has now shown that songbirds, a group containing over 4,000 species, can sense sweetness regardless of their primary diets. The study highlights a specific event in the songbird ancestors that allowed their umami (savoury) taste receptor to recognise sugar. This ability has been conserved in the songbird lin
