A new line of evidence, first announced last summer, suggests that the cosmic expansion rate may fall much closer to the rate predicted by early-universe measurements and the standard theory of cosmology.
But at Argonne National Laboratory in Illinois, physicist Chris Benmore and his colleagues are levitating objects with an unlikely tool: sound.Beyond the entertainment value, acoustic levitation is helping Benmore and his team do science: They're suspending pharmaceuticals and watching how molecules interact, by pointing the most intense X-ray source in the western hemisphere at the acoustic levitator.
Unlike teaching, where we have real consequences when we fail to modernize, such as poor evaluations and losing enrollment, there are no real consequences for the professional societies organizing the meetings or for presenting scientists.
He focused on two markers of infant health—gestational age and birth weight—and compared them with the data on police shootings in California over the same nine-year period.White and Hispanic infants didn’t seem to be affected, and police shootings of unarmed victims of other races didn’t produce a strong effect either.
Most jet engine designers test their creations on the ground.A Florida startup once just made model planes—but now it’s building little baby jet engines for drones.
In March, Yoshua Bengio received a share of the Turing Award, the highest accolade in computer science, for contributions to the development of deep learning—the technique that triggered a renaissance in artificial intelligence , leading to advances in self-driving cars , real-time speech translation , and facial recognition .Now, Bengio says deep learning needs to be fixed.
It’s called a solid-state greenhouse effect—light penetrates the surface, passes through the translucent ice, and then hits darker regolith, which warms up. Could an insulating material create a solid-state greenhouse effect warm enough to make Mars habitable?
The fake force allows a rotating reference frame to act like a stationary one. In the non-rotating frame, the ball just moved along with a constant velocity—just as it should with no net forces acting on it.
Some, like the wagon wheel illusion, rely on frame rate tricks (with the right camera settings, flowing water can appear to freeze in midair).
And, still staying within our solar system, we will swing by an asteroid called Gault that is being torn apart by our sun in a fun phenomenon called the YORP effect, or Yarkovsky–O'Keefe–Radzievskii–Paddack, named after the people who discovered it.
Notice how the balls look "bunched up" on the left side of the sound source but spread out on the right side? Here is a plot of the apparent ball frequency for a source moving at 4 m/s with the ball sound speed of 10 m/s.
Since December, Indian policymakers have taken a page from China’s playbook, enacting sweeping restrictions in an attempt to curtail the power of ecommerce behemoths like Amazon, and pushing proposals that would require internet companies to censor “unlawful” content, break user encryption, and forbid Indian data from being stored on foreign soil.
There is a Fortnite Effect, yes, but it's not being caused by the game's continuing utter dominance—the source is a lack of original thinking among developers and investors both. Activision-Blizzard announced that it would pour money into its games, increasing development staff up to 20 percent over the next year.
“We said, what if we replaced the urban area of Houston with cropland?” Using a system called the Weather Research and Forecasting model to simulate climate and its changes over a region (as opposed to models with lower resolution but wider geographic scope), that’s actually possible.
It’s called the entourage effect: THC, like a rock star, only reaches its full potential when it rolls with a crew, consisting of hundreds of other compounds in the plant that scientists know about so far.But the problem with researching a schedule I drug is that the government doesn’t want you to do it.
