Sri Lanka has become the latest victim of China’s toxic counterfeit culture. After receiving the first consignment of organic fertilizers from China, the Sri Lankan agriculture ministry has found that 20,000 metric tons of fertilizers are toxic.

Rearing animals for human consumption and clearing land to grow their feed causes untold environmental damage. Mass-producing plant-based proteins could be equally unsustainable. New technologies are being developed to grow pork, beef and chicken-like tissue in the lab, but can output be upscaled enough to make a real difference?

According to astronomers, several asteroids with diameters more than 10 meters collide with the surface of the solar system’s largest planet every year, causing explosions visible from Earth. Previously, such collisions were registered in 1,994 2009, 2,010 2012, 2,016 2017 and 2019.

If confirmed, this will be the ninth recorded impact on Jupiter since the first in July 1,994 when Comet Shoemaker-Levy 9 shattered into several smaller pieces, sinking one after another into the giant’s gas shell, leaving dark marks on the clouds of Jupiter, some of them the size of our planet.

Surgeons have successfully attached a pig’s kidney to a human and confirmed that the body accepted the transplant in a major scientific breakthrough, The New York Times reported.

This successful operation is a promising sign as scientists work to be able to use animal organs in life-saving transplants in humans.

Scientists altered a pig gene and engineered the kidney to eliminate sugar to avoid an immune system attack. In the past, the human body would reject the transplant due to the presence of glycan, a sugar molecule in pig cells.

The team used a high-resolution atomic force microscope (AFM) operating in a controlled environment at Princeton’s Imaging and Analysis Center. The AFM probe, whose tip ends in a single copper atom, was moved gradually closer to the iron-carbon bond until it was ruptured. The researchers measured the mechanical forces applied at the moment of breakage, which was visible in an image captured by the microscope. A team from Princeton University, the University of Texas-Austin and ExxonMobil reported the results in a paper published Sept. 24 in Nature Communications.

“It’s an incredible image—being able to actually see a single small molecule on a surface with another one bonded to it is amazing,” said coauthor Craig Arnold, the Susan Dod Brown Professor of Mechanical and Aerospace Engineering and director of the Princeton Institute for the Science and Technology of Materials (PRISM).

“The fact that we could characterize that particular , both by pulling on it and pushing on it, allows us to understand a lot more about the nature of these kinds of bonds—their strength, how they interact—and this has all sorts of implications, particularly for catalysis, where you have a molecule on a surface and then something interacts with it and causes it to break apart,” said Arnold.

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way.

The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It’s one large-ish asteroid, approximately 780 meters across — that’s Didymos proper — and a 160-meter “moonlet” in its orbit.

As the moonlet is more typical of the type likely to threaten Earth — there being more asteroids that are that size and not easily observed — we will be testing the possibility of intercepting one by smashing into it at nearly 15,000 miles per hour. This will change the speed of the moonlet by a mere fraction of a percent, but enough that its orbit period will be affected measurably. Knowing exactly how much will help us plan any future asteroid-deflection missions — not surprisingly, there isn’t a lot of existing science on ramming your spacecraft into space rocks.

Is there anything out there?

The concept of primordial black holes has waxed and waned in scientific circles over the decades. At first, it was a fascinating possibility. After all, the first few seconds of the big bang were pretty heady times, and there may have been large enough differences in density to generate black holes of all sorts of sizes, from microscopic to gigantic. But repeated observations have continually been unable to come up with any conclusive evidence for their existence.

And then there’s dark matter, the mysterious substance that makes up the vast bulk of matter in the cosmos. Scientists aren’t exactly sure what lies behind dark matter, and primordial black holes are a tantalizing possibility.
