These remaining caves exist on Earth and high-resolution pictures taken by interplanetary probes inferred lava tubes on Mars and Luna by observing linear cavities and sinuous collapse chains where the galleries cracked. A new paper measured the size and gathered the morphology of lunar and Martian collapse chains (collapsed lava tubes), using digital terrain models obtained through satellite stereoscopic images and laser altimetry taken by interplanetary probes.
Its genome shares features with those of mammals such as the platypus and echidna.
Some sequences of DNA move or jump location, they are even referred to as 'jumping genes', and those found in the tuatara are most similar to those found in platypus while others are more similar to those in lizards.
Archeological finds are not new on the Arabian peninsula. There is evidence for lithics (stone tools) but evidence showed they were less advanced than northeast Africa or the Levant.
In Europe, the Levant and Africa, the Middle Paleolithic showed use of Levallois flaking methods, including predetermined forms of flaking products. Like spear tips, which gave hunters a big advantage in food. But new work also shows fluting, which was more common n Arabia.
'Deepfakes' Are The Most Worrisome Form Of Artificial Intelligence For Terrorism And Crime - And 5 Others To Think About
The 20 ways were ranked in order of concern based on the harm AI could cause, the potential for criminal profit or gain, how easy they would be to carry out and how difficult they would be to stop.
What does a pandemic smell like? If dogs could talk, they might be able to tell us.
We’re part of an international research team, led by Dominique Grandjean at France’s National Veterinary School of Alfort, that has been training detector dogs to sniff out traces of the novel coronavirus (SARS-CoV-2) since March.
Most adults will remember spending much of their childhood playing outdoors without much parental supervision. But fears for children’s safety plus the demands of modern life mean many parents don’t allow their children the same freedoms.
To make it suitably ironic, environmentalists who have spent decades and $40 billion on campaigns saying single-family homes in suburbia are a blight on nature and we should all live in urban apartments are now claiming we should be growing vegetables and trading them with each other to create a more sustainable future.
The public was sold a false bill of goods by “grassroots” anti-vaping activists when they crusaded against e-cigarettes and e-cigarette flavors in front of city councils, state houses and the U.S. Congress throughout 2019.
We were told that the seductively delicious flavors of Juuls and other e-cigarettes were luring youngsters to dangerous nicotine products. To curb underage vaping, the government needed to get rid of the flavored nicotine replacement products.
The COVID-19 pandemic has led to rampant new use of personal protective equipment (PPE) but we're also facing a problem of more garbage in landfills. It could be trivial but in a world where people people about Keurig K-cups, technology to turn billions of items of disposable PPE from its polypropylene (plastic) state into biofuels mean it can be a viable consideration.
A study in Biofuels explains that the transformation into biocrude, a type of synthetic fuel, will not just prevent the severe after-effects to humankind and the environment but also produce a source of energy.
used to help explain the brain's understanding of the body, as well as scores of clinical disorders, has been dismissed as not fit-for-purpose in a new academic paper from the University of Sussex.
The Rubber Hand Illusion, where synchronous brush strokes on a participant's concealed hand and a visible fake hand supposedly give the impression of illusory sensations of touch and of ownership of the fake hand, has been considered accepted science for more than 20 years. Psychologists believe it increases knowledge of the brain's understanding of the body, as well as scores of clinical disorders.
Unable to reproduce on their own, viruses replicate by infecting a living organism's cells and getting the cells to make copies of them. Two main options exist for copies of a virus's genetic structure made in the cell: stay in the cell as a template for making even more copies or get packaged as a new virus and leave in an attempt to infect other cells. The stay strategy initially produces copies of the genetic code faster, while the leave strategy emphasizes newly infecting cells. How do they evaluate these opposing evolutionary strategies?
It has continuously existed far longer than any other alpine flora on Earth, which can infer how modern biotas have been shaped by past geological and climatic events.
COVID-19 has thrown professional baseball in North America a curveball. An outbreak among players for the Miami Marlins, that has spread to the Philadelphia Phillies and St. Louis Cardinals, brings into question the infection control protocols touted by Major League Baseball.
The data used were the social ties of 28,238 adults aged 45 to 85 and their waist circumference, body mass index and general obesity. These results are only exploratory, they cannot create a causal link and since they are based on surveys have numerous confounders.
Next generation gaming, beyond better graphics, requires establishing new relationships between game progress and entertainment experience. Chess is a much different experience versus another person than it is a computer, as is Poker. Many less experienced people play far more conservatively versus people because computers don't feel real. And then there are some sports where the experience is limited because you aren't very good at them, such as sports.
If a particle is an elementary body, how many individual, distinct properties can it really have? For the word "elementary" means that it is intrinsically simple! But things are not so clear-cut in the subnuclear world. An elementary particle, while devoid of inner structure and dimensions, still has a number of measurable attributes. For the Higgs boson we may size up:
- mass (of course!)
Yet that would violate a central dogma of chemistry; that molecular diffusion and chemical reaction are unrelated.
The ripples generated by chemical reactions, especially when catalyzed - accelerated by substances not themselves consumed - propagate long-range. This challenges the view that molecular motion and chemical reaction are decoupled, and that reactions affect only the nearby vicinity.
