With a big assist from artificial intelligence and a heavy dose of human touch, Tim Cernak’s lab at the University of Michigan has made a discovery that dramatically speeds up the time-consuming chemical process of building molecules that will be tomorrow’s medicines, agrichemicals or materials.

The discovery, published in the Feb. 3 issue of Science, is the culmination of years of chemical synthesis and data science research by the Cernak Lab in the College of Pharmacy and Department of Chemistry.

The goal of the research was to identify key reactions in the synthesis of a molecule, ultimately reducing the process to as few steps as possible. In the end, Cernak and his team achieved the synthesis of a complex alkaloid found in nature in just three steps. Previous syntheses had taken between seven and 26 steps.

A small team of astrophysicists affiliated with several institutions in China has found evidence that suggests if wormholes are real, they might magnify light by 100,000 times. In their paper published in the journal Physical Review Letters, the group describes the theories they have developed and possible uses for them.

Prior theoretical efforts have suggested that wormholes might exist in the universe, described as tunnels of a sort, connecting different parts of the universe. Some in the physics community have suggested that it may be possible to traverse such tunnels, allowing for faster-than-light travel across the universe. The researchers note that prior research has shown that black holes have such a strong gravitational pull that they are able to bend light, a phenomenon known as microlensing. They then wondered if wormholes, if they exist, also exhibit microlensing.

Proving that wormholes cause microlensing would, of course, involve first proving that wormholes exist. Still, the researchers suggest that general relativity and other theories could clarify whether the idea is even possible. In their work, they discovered that it was possible to calculate how an electric charge associated with a wormhole would warp the light passing by it. They also found theoretical evidence that wormhole microlensing would be similar to black hole lensing, which, they note, would make it difficult to tell the two apart.

After launching with SpaceX in December, Lunar Flashlight ran into trouble in deep space. Now the mission is eyeing a high-Earth orbit that will allow moon flybys.

Turkey’s stock exchange suspended trading for five days and canceled all trades executed on Wednesday, following a selloff that erased billions of dollars from the value of its main equities gauge after two devastating earthquakes.

While talent matters, the good news is we all learn at basically the same rate—and can “learn anything we want.”

We’re used to thinking of space as continuous.

A stone can be anywhere in space. It can be here. Or it can be an inch to the left. Or it can be half an inch further to the left. Or it can be an infinitesimal fraction of an inch even further to the left. Space is infinitely divisible.

“I think it’s going to be inconclusive, if not impossible to demonstrate conclusively,” one physicist said of the possible interstellar comet.
