If we want to colonize Mars, we’re going to need to figure out a way to feed ourselves there, and continuously sending food to the Red Planet isn’t a sustainable plan.
But now, a team of researchers thinks it’s figured out a way to produce enough food on Mars to feed a million people — and they say their plan to make Martian colonists self-sufficient would take just a hundred years to implement.
Tesla CEO Elon Musk has a weak spot for potty humor.
First, the carmaker introduced a “fart app” for its electric vehicles, which generates rude bathroom sounds.
Now, Musk says Teslas will soon be getting “customized horn and movement sounds,”— including “goats” and “farts,” according to a emoji-laden Sunday tweet.
When it comes to regeneration, some animals are capable of amazing feats — if you cut the leg off a salamander, it will grow back. When threatened, some geckos drop their tails as a distraction, and regrow them later.
Other animals take the process even further. Planarian worms, jellyfish, and sea anemones can actually regenerate their entire bodies after being cut in half.
Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals pull off the feat, and uncovered a number of DNA switches that appear to control genes for whole-body regeneration. The study is described in a March 15 paper in Science.
A crowdfunded startup wants to encourage homeowners to fight insect invasions with a natural enemy.
In a certain sense, physics is the study of the universe’s symmetries. Physicists strive to understand how systems and symmetries change under various transformations.
New research from Washington University in St. Louis realizes one of the first parity-time (PT) symmetric quantum systems, allowing scientists to observe how that kind of symmetry—and the act of breaking of it—leads to previously unexplored phenomena. The work from the laboratory of Kater Murch, associate professor of physics in Arts & Sciences, is published Oct. 7 in the journal Nature Physics.
Other experiments have demonstrated PT symmetry in classical systems such as coupled pendulums or optical devices, but this new work in Murch’s lab, along with experiments in China by Yang Wu et al., reported in Science this May, provides the first experimental realization of a PT-symmetric quantum system.
As a student astronomer scanning the skies with homemade instruments a quarter of a century ago, Didier Queloz spent months doubting the data that led him to an inescapable conclusion: he’d just discovered the first planet outside Earth’s solar system.
The Swiss scientist had spent much of his PhD research refining techniques to detect so-called exoplanets, which until one fateful night in October 1995 had previously only existed in the realm of science fiction.
Queloz and his colleague Michel Mayor, who on Tuesday were awarded the Nobel Prize for Physics for their pioneering work, had already overcome a number of obstacles in their galaxy-wide search.
Methane bomb is ticking.
Researchers were able to see the greenhouse gas bubbling through the seawater.
Walmart has over 100,000 different machine learning or AI-based projects currently in production. The success rate, however, is still just 75 percent.
With a self-guiding drone hovering over your shoulder, a not-too-humanoid robot sidekick as your wingman, and a four-legged fetch ‘bot trotting along beside, the day when you can surround yourself with a whole gaggle of AI-powered helpers is already here … even if it’s still the wee hours of the early morning.
Whether by air, on wheels, or even on padded little robot paws, the technology that drives our mechanized helpers is reaching that autonomous point at which the droids are able to think for themselves as they carry out their limited missions. Sure, they’re not quite ready to cross platforms and begin communicating with one another just yet, but at least they all can communicate with you — which pretty much makes you the star character in your budding little electronic entourage.
