Shatner will take a seat on Blue Origin's second launch from west Texas on 12 October, the spac
A team of researchers have developed a model to track the pathways and fate of plastic debris from land-based sources in the Mediterranean Sea. They show that plastic debris can be observed across the Mediterranean, from beaches and surface waters to seafloors, and estimate that around 3,760 metric tons of plastics are currently floating in the Mediterranean.
A team of space scientists has published a paper in Annual Review of Astronomy and Astrophysics suggesting that there may be an Earth- or Mars-sized planet orbiting beyond Neptune. They further suggest that simulations of the creation of the solar system show that such a planet may have been pushed from the outer regions of the solar system by the gas giants.
The idea that dictatorships get things done while democracies dither has an ancient provenance and enduring appeal. When times were tough in the ancient Roman republic, the Senate appointed a strongman with virtually unlimited powers (but a temporary term of office) to tackle the crisis. Abraham Lincoln, the savior of American democracy and the Great Emancipator, suspended the writ of habeas corp
A few months ago , I saw Boris Johnson recount a story about his life that I'd never heard before—and he said something that was not, strictly speaking , true. With most politicians, hearing a new tale can be unremarkable, but with Johnson—the subject of at least two biographies, countless newspaper and magazine articles, and someone who has been at the center of British political life for decade
Prodigies such as Emma Raducanu spend thousands of hours honing their skills, but could anyone deliver a world-class performance with enough dedication? At the end of every edition of his children's TV show Record Breakers, Roy Castle used to sing: "If you want to be the best, if you want to beat the rest, dedication's what you need ." But is it all you need? Tennis star Emma Raducanu seemingly c
'Stunning' neuroscientific advance gives hope to those with mental illness not helped with drugs A woman with severe depression has been successfully treated with an experimental brain implant in a "stunning" advance that offers hope to those with intractable mental illness. The device works by detecting patterns of brain activity linked to depression and automatically interrupting them using tin
On September 28, Amazon introduced Astro, a "household robot." Amazon's launch video promises that the $999 robot, which is squat with two wheels and a rectangular screen that features two orbs for eyes, will be able to do things like watch your home or join impromptu dance parties. This being Amazon, there's good reason to be skeptical, especially since Astro is essentially a giant camera on whe
J onathan Franzen writes big books about small lives. This may sound like a curious characterization of a writer who has sweated to position himself as an encyclopedic chronicler of wide-scale cultural change in each of his five fat novels to date, the shortest of them clocking in at 517 pages. Yet his fiction is typically set in claustrophobic enclaves. His characters don't hail from New York or
Sarah, a 36-year-old woman living in California, had lived with chronic depression for five years. She felt suicidal multiple times an hour and was unable to make decisions about basic questions like what to eat. Nothing she had tried to treat it, including electroconvulsive therapy, had helped. Then, in June 2020, she had an implant inserted into her skull that zaps the parts of her brain that c
Half a degree Celsius may not seem like much, but climate experts say a world that has warmed 1.5 degrees Celsius above 19th-century levels compared to 2C could be the difference between life and death.
Using four radio telescopes, astronomers from the National Astronomical Observatory of Japan and elsewhere have conducted multi-frequency multi-epoch radio observations of a radio-loud magnetar known as XTE J1810-197. Results of the study, presented September 24 on the arXiv pre-print repository, could help us better understand the nature of this peculiar object.
We often appreciate the world around us in terms of its glorious sights, stirring sounds and evocative smells, all of which mark important stimuli and changes in our environment. But senses that are no less crucial to our survival yet often taken for granted are our abilities to register heat, cold and touch, a form of perception called somatosensation. Because of them, we can feel the warmth of.
In a surprising discovery, an international team of researchers, led by scientists in the University of Minnesota Center for Quantum Materials, found that deformations in quantum materials that cause imperfections in the crystal structure can actually improve the material's superconducting and electrical properties.

Did they just get out of a rough meeting or a
Scientists at the University of Maryland Center for Environmental Science have sequenced the genome of the blue crab. The best way to understand an organism is to understand its genetic makeup, also known as its genome. Once the code is understood, it reveals many secrets of how the organism works. Researchers plan to investigate the genetics of growth and reproduction, and the genome will be made
The pink notebook my mother kept when she was sick contains 18 entries, most of them shorter than a haiku. The pages list medications and surgeries, the names of family members who sent money, and which body parts hurt and how badly. One entry, from October 1995, reads: "Neck (severe pain) Coming out of the mall to cold air." I was 5 that day; my sister was 3. We were leaving the mall after takin
When Ray Kelly was appointed commissioner of the New York Police Department, in 1992, he announced that his No. 1 priority was to recruit more Black officers to the force. "Without these actions, there will be increased tension between the communities and the police," Kelly told The New York Times . "Tension leads to hostilities and that will lead to more cries of racism in the department." Kelly
When Pluto passed in front of a star on the night of August 15, 2018, a Southwest Research Institute-led team of astronomers had deployed telescopes at numerous sites in the U.S. and Mexico to observe Pluto's atmosphere as it was briefly backlit by the well-placed star. Scientists used this occultation event to measure the overall abundance of Pluto's tenuous atmosphere and found compelling eviden
For several years now, large investment firms have used public proclamations, like BlackRock's "Dear CEO" letters, to signal their commitment to corporate social responsibility. New research shows the companies these firms invest in are picking up the signal and repeating the message.

USB Type-C only appeared on the scene a few years ago, but it has already become almost ubiquitous on phones, tablets, laptops, and more. The EU is even considering making USB-C a requirement on a huge swath of consumer electronics. However, just because you see the distinctive oval-shaped USB-C plug on a device does not mean it automatically supports high-speed data or fast charging. The non-pro

Here at ET we occasionally delve into topics for no particular reason beyond curiosity. In this case, that's lasers. At the consumer level, we're surrounded by products that rely on lasers — optical media, barcode scanners, fiber optics, and printers are all common — but for this article, we decided to scale up a bit. There are a couple contenders for the world's biggest laser, and they're all in
Analyzing 10 minutes of people's idle thoughts indicates two tendencies: one that veers toward rumination, and the other toward inspiration. As reported in the journal Scientific Reports , 78 participants were trained to voice their thoughts aloud for 10 minutes while sitting alone in a room without access to electronic devices. Researchers used audio equipment to record those thoughts, then tran
A new study by Monash University researchers has applied the Rapid Evidence Review method for the first time to peatland conservation and suggests the technique can be applied to other environmental problems.
River winds are induced by the daily thermal contrast between the land and the river. During the daytime, warmer temperatures over the land lead to lighter air masses that are lifted. The air masses in turn drive onshore air movement from the river toward the land. Subsequently, the air subsides over the river. The result is a closed local air circulation cell in the vertical plane (Figure 1). At
Quantum computing is an exciting technology with tremendous potential. However, at present that is exactly what it remains – a potential, without any current application. It's actually a great example of the challenges of trying to predict the future. If quantum computing succeeds, the implications could be enormous. But at present, there is no guarantee that quantum computing will become a reali
To cool off in summer, there's nothing better than a walk in the woods. Trees act as a buffer that cools the air beneath their foliage in summer and warms it in winter. This phenomenon is caused not only by the protection that the forest canopy provides, but also by the transpiration of trees in summer: trees absorb cooler water from the soil, and this water is then transported up to the leaves, e
In 2030, almost 1 in 3people around the world will still be mainly using polluting cooking fuels and technologies, a major source of disease and environmental destruction and devastation, new research warned. This rises to more than 4 in 5 in sub-Saharan Africa, where the number of people mainly using polluting fuels is growing at an alarming rate.
They look like jellyfish but they aren't. They seem inoffensive but are efficient predators—occasionally, they even eat fish. They are gelatinous and very delicate—and extremely rarely do they fossilize!

ʻUaʻu kani, or wedge-tailed shearwater, is a seabird species common in Hawaiʻi. Though historically found nesting along coastlines, human development in these areas has likely reduced the availability of nesting habitats, pushing the seabird colonies to nest in undeveloped islets.
Imagine there's a bus that arrives every 30 minutes on average and you arrive at the bus stop with no idea when the last bus left. How long can you expect to wait for the next bus? Intuitively, half of 30 minutes sounds right, but you'd be very lucky to wait only 15 minutes.
Machine learning algorithms pervade modern life. They shape decisions about who gets a mortgage, who gets a job, and who gets bail, and have become so enmeshed in our political and economic processes that some scientists argue we are witnessing the emergence of "algorithmically infused societies."
Most stars including the sun generate magnetic activity that drives a fast-moving, ionized wind and also produces X-ray and ultraviolet emission (often referred to as XUV radiation). XUV radiation from a star can be absorbed in the upper atmosphere of an orbiting planet, where it is capable of heating the gas enough for it to escape from the planet's atmosphere. M-dwarf stars, the most common type

The Covid-19 pandemic has exacerbated food insecurity in the U.S., but it may have also provided a roadmap for mitigating the problem. The crisis fueled the growth of a vast online marketplace for food and grocery delivery — a marketplace that can be tapped to modernize government nutrition assistance.
Ett läkemedel mot alkoholism visar lovande resultat som möjlig behandling för personer med sexmissbruk. Det visar en avhandling från Umeå universitet. Nu görs en större studie av medicinen. – Sexmissbruk är en sjukdom som innebär lidande och riskerar att leda till allvarliga konsekvenser för såväl personen själv som för omgivningen. Därför är det välkommet med fler möjliga behandlingsalternativ,
Antivaxxers have long appealed to "natural immunity" as being somehow inherently superior to vaccine-induced immunity, which is apparently "artificial". This is a trope that comes from alternative medicine concepts about purity and contamination that is now endangering us in the age of the pandemic. The post first appeared on Science-Based Medicine .

Om inte sättet att bruka skogen förändras finns risk att den traditionella rennäringen försvinner. Det menar forskare som studerar renarnas vinterföda, laven. Laven håller nämligen på att ta slut. På bara drygt 30 år har hälften av laven i de lavrika skogarna försvunnit, och utan stödfoder svälter renarna.
Klockan 11.30 får vi veta. Då kommer Nobelförsamlingen på Karolinska Institutet meddela vem eller vilka som får årets Nobelpris i medicin eller fysiologi. Bodil Appelquist, vetenskapsreporter på SVT, hoppas på ett pris till en upptäckt som betytt ofantligt mycket för världen de senaste åren.
