It’s time to celebrate another first in the field of quantum physics: scientists have been able to ‘teleport’ a qutrit, or a piece of quantum information based on three states, opening up a whole host of new possibilities for quantum computing and communication.

Up until now, quantum teleportation has only been managed with qubits, albeit over impressively long distances. A new proof-of-concept study suggests future quantum networks will be able to carry much more data and with less interference than we thought.

If you’re new to the idea of qutrits, first let’s take a step back. Simply put, the small data units we know as bits in classical computing can be in one of two states: a 0 or a 1. But in quantum computing, we have the qubit, which can be both a 0 and 1 at the same time (known as superposition).

Alkahest, a California-based biotech start-up, has just revealed some compelling early results from an ongoing Phase 2 trial into the efficacy of its novel formulation of plasma proteins derived from young blood, developed to slow, or even stop, the cognitive decline associated with Alzheimer’s disease.

Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve the main features of the Unruh effect.

Well, that depends on your frame of reference, but even so, does that mean that we need to stop worrying about aging? Not really.

The tardigrades were part of a “lunar library” that Spivack’s foundation had put together. According to Wired, the package was about the size of a DVD and contained human DNA—including Spivack’s own—as well as 30 million pages of information on mankind’s knowledge and thousands of dehydrated tardigrades.

Tardigrades are known as one of the toughest creatures on Earth. They are microscopic, measuring about 0.012 to 0.020 inches in length, and can withstand temperatures of up to 304 degrees Fahrenheit and can survive being frozen alive. One tardigrade is known to have survived being frozen for 30 years. They can also live without water for up to a decade by shriveling up and placing themselves in a state of suspended animation—a trait DARPA is currently studying in the hope of preserving soldiers injured on the battlefield.

It’s amazing these plants exist at all.

In addition to having access to large colonies of monkeys and other species, animal researchers in China face less public scrutiny than counterparts in the United States and Europe. Ji, who says his primate facility follows international ethical standards for animal care and use, notes that the Chinese public has long supported monkey research to help human health. “Our religion or our culture is different from that of the Western world,” he says. Yet he also recognizes that opinions in China are evolving. Before long, he says, “We’ll have the same situation as the Western world, and people will start to argue about why we’re using a monkey to do an experiment because the monkey is too smart, like human beings.”

BEIJING, GUANGZHOU, JIANGMEN, KUNMING, AND SHANGHAI—Early one February morning, researchers harvest six eggs from a female rhesus macaque—one of 4000 monkeys chirping and clucking in a massive outdoor complex of metal cages here at the Yunnan Key Laboratory of Primate Biomedical Research. On today’s agenda at the busy facility, outside Kunming in southwest China: making monkey embryos with a gene mutated so that when the animals are born 5 months later, they will age unusually fast. The researchers first move the eggs to a laboratory bathed in red light to protect the fragile cells. Using high-powered microscopes, they examine the freshly gathered eggs and prepare to inject a single rhesus sperm into each one. If all goes well, the team will introduce the genome editor CRISPR before the resulting embryo begins to grow—early enough for the mutation for aging to show up in all cells of any offspring.
