I actually like this program.
“It watches what you’ve done in the past, what you’ve gotten right, and what you’ve gotten wrong,” he explained. “And then it tries to give you things that are not too easy or not too hard, but are sort of what educational psychologists would say are in your ‘zone of proximal development.’”.
In the wake of a noted IPO, EdTech player Duolingo showed off AI-infused updates to its language lesson platform.

Lasers that ‘softly’ burn paper could be the next evolution in printing. Former students of the University of Technology in Delft, Netherlands, have developed a technology that can print on any kind of paper without consumables, such as toner or ink.
This technique is not unlike burning paper using a magnifying glass and sunlight.
The same principle has been created in a laboratory using an infra-red laser ray, which passes through the set of special lenses and burns the paper, printing black carbon dots.
Circa 2015 Clues of the genetic material in vultures could give rise to humans that have immunity to nearly all bacteria and viruses.
WASHINGTON WASHINGTON (Reuters) — A diet of putrid rotting flesh may not be your cup of tea, but to the cinereous vulture, found across southern Europe and Asia, it is positively delightful. This tough bird, it turns out, is genetically wired to thrive on the stuff.
Researchers on Tuesday said they have sequenced the genome of this big scavenger, also called the Eurasian black vulture, identifying genetic traits that account for a stalwart stomach and powerful immune system that let it carry on eating carrion.
They pinpointed genetic features related to gastric acid secretion that help explain this vulture’s ability to digest carcasses and other features linked to its immune system defense against microbial and viral infections from decomposing flesh.
Why not eradicate disease for everyone?
Zolgensma – which treats spinal muscular atrophy, a rare genetic disease that damages nerve cells, leading to muscle decay – is currently the most expensive drug in the world. A one-time treatment of the life-saving drug for a young child costs US$2.1 million.
While Zolgensma’s exorbitant price is an outlier today, by the end of the decade there’ll be dozens of cell and gene therapies, costing hundreds of thousands to millions of dollars for a single dose. The Food and Drug Administration predicts that by2025it will be approving 10 to 20 cell and gene therapies every year.
I’m a biotechnology and policy expert focused on improving access to cell and gene therapies. While these forthcoming treatments have the potential to save many lives and ease much suffering, health care systems around the world aren’t equipped to handle them. Creative new payment systems will be necessary to ensure everyone has equal access to these therapies.
Bill Gates made headlines for becoming the largest private farmland owner in the U.S. But he’s not the only one. Some of the wealthiest landowners including Jeff Bezos, John Malone and Thomas Peterffy are buying up forests, ranches and farmlands across the United States. Why? Watch the video to find out.
Investments in farmland are growing across the country as people, including the ultra-wealthy like Bill Gates, look for new ways to grow their money.
In 2,020 Gates made headlines for becoming the largest private farmland owner in the U.S. He had accumulated more than 269,000 acres of farmland across 18 states in less than a decade. His farmland grows onions, carrots and even the potatoes that are used to make McDonald’s French fries.
“It’s an asset with increasing value,” American Farmland Trust CEO John Piotti said. “It has great intrinsic value and beyond that, it is a limited resource.”

In order to find a way to trick the body into making new B cells, the researchers probed one of the ways that the body naturally replenishes its supply. Patients undergoing treatment for multiple sclerosis had their MBC stock depleted, at which point their body rapidly started to produce new B cells.
The team identified the specific hormones that shut B cell production down again once stores were replenished, and realized that deactivating the hormone results in the body producing extra B cells left and right. And going forward, they hope to turn that hormonal trick into a new rejuvenating treatment for the elderly and immunocompromised.
“We found specific hormonal signals produced by the old B cells, the memory cells, that inhibit the bone marrow from producing new B cells,” Melamed told The Jerusalem Post. “This is a huge discovery. It is like finding a needle in a haystack.”
Astronomers have used an “X-ray magnifying glass” to study a black hole system in the early Universe. The amplification and magnification of light by an intervening galaxy allowed the detection of two distant X-ray-emitting objects. The objects are either two growing supermassive black holes.
A structural model of the SARS-CoV-2 spike protein as the virus fuses with host human cells reveals an opportunity to disrupt dynamics and halt transmission.
Scientists have simulated the transition of the SARS-CoV-2 spike protein structure from when it recognizes the host cell to when it gains entry, according to a study published on August 31 2021, in eLife.
The research shows that a structure enabled by sugar molecules on the spike protein could be essential for cell entry and that disrupting this structure could be a strategy to halt virus transmission.
New material maintains borophene ’s electronic properties, offers new advantages.
For the first time, Northwestern University engineers have created a double layer of atomically flat borophene, a feat that defies the natural tendency of boron to form non-planar clusters beyond the single-atomic-layer limit.
Although known for its promising electronic properties, borophene — a single-atom.
