The first commercial space hotel will be more like a cruise ship than Stanley Kubrick's sleek space station from 2001, says Tim Alatorre, senior design architect of the Von Braun Space Station. The Gateway Foundation is designing the world's first space hotel – the Von Braun Space Station – with the aim of making visiting space accessible to everyone.
In the last few years, evidence has been emerging that several psychedelics seem to alleviate the symptoms of depression. Now scientists have tested a new compound - and early trials indicate that it, too, has potential.
Publication of the largest-ever study of the roles of genes in homosexual behavior is fanning the debate over whether being gay is due to genes or environment. First reported at a genetics conference in 2018, the study found five genetic variants associated with having a same-sex sexual partner (SN: 10/20/18). But those variants, called SNPs, don’t predict people’s sexual behavior, researchers report in the Aug. 30 Science.
Canadian astronomers at McGill University, using satellite data collected over the past decade, have come up with a spectral “fingerprint” of Earth that could be compared to atmospheric signatures from exoplanet transits to help determine their ability to support life.
“Death by Dark Matter.” That’s not the name of your new favorite metal band; it’s the literal title of a new study by a trio of American of physicists
Machine learning can help manage a wide range of mental health disorders. But the psychiatric profession is worryingly unprepared for this change, according to a global survey.
A startup that spun out of Cambridge University claims a battery breakthrough that can charge an electric car in just six minutes. It’s something we heard before, but the difference here is that they claim that they can commercialize the new battery as soon as next year.
Two detections of gravitational waves set off a flurry of excitement among astronomers. Was it a double observation of a single black-hole merger, or just a cosmic coincidence?
The same brain regions are activated when both reading and listening to stories, a new study says. It's a new insight into how our brains process semantic meaning.
The milestone was a long time coming.
In 1904, the Brazilian city of Rio de Janeiro shook with violence as citizens rioted. Property was destroyed, dozens were wounded, and 30 people lost their lives as the population rose up against a perceived common enemy: a mandatory vaccine for smallpox
E-cigarette “vaping” is widely assumed to be safer than cigarette smoking, but scientists at the UNC School of Medicine have uncovered evidence suggesting that vaping promotes the same cellular responses found in smokers who suffer from emphysema.
The oldest stars in our Galaxy are also the busiest, moving more rapidly than their younger counterparts in and out of the disk of the Milky Way, according to new analysis carried out at the University of Birmingham.
Silicon’s reign in cutting-edge electronics may soon over. The carbon nanotube could be its successor.
On December 2nd, 1942, a team of scientists led by Enrico Fermi came back from lunch and watched as humanity created the first self-sustaining nuclear reaction inside a pile of bricks and wood underneath a football field at the University of Chicago. Known to history as Chicago Pile-1, it was celebrated in silence with a single bottle of Chianti, for those who were there understood exactly what it meant for humankind, without any need for words.
Researchers have successfully fertilized several northern white rhino eggs with the sperm of the last two bulls, Suni and Saut, both now deceased.
Five of Jupiter's many moons have new names thanks to suggestions from the public.
Pet owners are being urged by vets to feed their dogs and cats on a diet rich in insects. The British Veterinary Association (BVA) says some insect-based foods may be better for pets than prime steak. The vets expect resistance from some pet lovers, but they say surveys suggest many would accept insect-based food.
But it’s not clear that eating ‘people food’ is necessarily bad for urban birds.
NASA has officially opened its new supercomputer, Aitken, at the Ames Research Center in Silicon Valley. It uses a modular design which requires less electricity and power than traditional facilities and and it will allow researchers to run complex simulations more quickly.
According to a study published in Current Biology in 2015, children raised without religion tend to be kinder than children brought up in very religious households. The study was a collaborative effort between numerous academics from seven different universities that are spread out all over the world.
Europe is in for another heat wave after this weekend as strong upper level ridge / Omega blocking pattern establishes. Temperatures will be back into low/mid 30s across many parts of our continent. Very warm weather is also expected across Scandinavia.
A study published in the journal Scientific Reports provides new insights into the effects of music on thoughts. The research indicates that heroic music tends to evoke more empowering and motivating thoughts, while sad music tends to evoke more relaxing or depressive thoughts.
Scientists have identified a specific gene they believe could be a key player in the changes in brain structure seen in several psychiatric conditions, such as schizophrenia and autism. The team from Cardiff University’s Neuroscience and Mental Health Research Institute has found that the deletion of the gene CYFIP1 leads to thinning of the insulation that covers nerve cells and is vital for the smooth and rapid communications between different parts of the brain.
A new study, published in the journal Clinical Psychological Science, suggests that the time adolescents are spending on their phones and online is not that bad. The study tracked young adolescents on their smartphones to test whether more time spent using digital technology was linked to worse mental health outcomes.
A puppy pal that gets sprayed by a skunk is no friend to human noses. The nasty odor can linger for weeks or more. But at least one kind of Tolypocladium fungi makes a chemical that can snuff out the stink. Called pericosine, it reacts with skunk spray’s sulfur-containing compounds, forming residues that aren’t offensive to the nose and can be more easily washed away, researchers report in the July 26 Journal of Natural Products.
NASA is examining a claim that an astronaut improperly accessed the bank account of her estranged spouse from the International Space Station, The New York Times reported Friday -- potentially the first criminal allegation from space.

Two NASA astronauts successfully installed a new docking adapter Wednesday for incoming SpaceX and Boeing vehicles that may arrive with crew as early as this year.
Look at anything made from trees—a ream of paper, a cardboard box, lumber—and it's probably stamped with the logo of the Forest Stewardship Council (FSC) or an equivalent organization. These nonprofits certify that forests are managed sustainably, and one common requirement is no genetically modified (GM) trees. But that ban hinders research and should change, researchers say in today's issue of Science. The technology, they argue, has important potential to remedy many pressing problems facing forests.
There is a strange forest in an otherwise unremarkable stretch of empty land north of San Francisco, where 42 steel trees sweep their parabolic canopies across the skies like industrial sunflowers. It’s quiet here, at the Allen Telescope Array, but the silence is deceiving. Just ask the trees, which are condemned to listen to a shrieking cosmos so that they might hear an extraterrestrial whisper—a whisper so faint that the sound of a snowflake falling to the earth is deafening by comparison. The astronomers who walk among these trees are preoccupied by the Big Question: What will the whisperer say? Will it be a greeting? A warning?
Oil spills can spell big trouble for the environment, and an efficient and swift response is critical in trying to contain the problem. In the not-too-distant future folks dealing with such incidents may have a robotic helper to call on...
One of the sources of mysterious energy blasts could be relatively nearby, scientists say
Although it outnumbers regular matter by a ratio of five to one, dark matter is frustratingly elusive. Many experiments have been and are being run to try to hunt down different types of candidate particles, but so far no direct trace has been found of any of them. Now, researchers from Max Planck have proposed a new hypothetical particle that might be behind dark matter – the superheavy gravitino – and outlined just how we might find them.
Nepal will make the Everest region a plastic-free zone by 2020 by banning single-use plastics, a move that will curb excessive pollution on the highest point of the Earth’s surface. The executive council of Khumbu Pasang Lhamu Rural Municipality in Solukhumbu district reached this decision on Wednesday, the Efe news reported.
During colonoscopy, air insufflation to distend the lumen and facilitate careful inspection and scope insertion can induce pain and cause discomfort. Carbon dioxide (CO ) insufflation can decrease abdominal pain and discomfort during and after colonoscopy. ...
The technology is likely to revolutionize the lenses used in VR/AR headsets as well.
Mars has the closest resemblance to Earth in our solar system. So, when humans become capable of interplanetary travel and consider colonising any planet, Mars would automatically be the first target due to its proximity and similarity to Earth.
It’s not as morbid as you think; having a reliable way of predicting people’s mortality, especially as they age, could help to improve how doctors treat disease.
It’s a race to the skies in terms of which company actually deploys an on-demand air taxi service based around electric vertical take-off and landing aircraft. For its part, German startup Volocopter is taking another key step with the revelation of its first aircraft designed for actual commercial use, the VoloCity. The VoloCity is the fourth-generation eVTOL vehicle that Volocopter has created, but the first three were created for testing and demonstration purposes, and have flown more than 1,000 times in service of that goal.
Legumes could be the answer, writes Richard Trethowan from the University of Sydney, Australia.
"To look forward to the Moon, we need to learn from the past."
Fast radio bursts are getting more attention from scientists, who can now detect more of them.
A team of scientists hauled 500 kilograms of fresh snow back from Antarctica, melted it, and sifted through the particles that remained. Their analysis yielded a surprise: The snow held significant amounts of a form of iron that isn't naturally produced on Earth.
