Researchers from the University of California, Davis, and an international team of scientists have used the genome-editing tool CRISPR-Cas to create disease-resistant rice plants, according to a new study published in the journal Nature June 14.

Small-scale field trials in China showed that the newly-created rice variety, developed through genome editing of a recently discovered gene, exhibited both high yields and resistance to the fungus that causes a serious disease called rice blast. Rice is an essential crop that feeds half of the world’s population.

Guotian Li, a co-lead author of the study, initially discovered a mutant known as a lesion mimic mutant while working as a postdoctoral scholar in Pamela Ronald’s lab at UC Davis. Ronald is co-lead author and Distinguished Professor in the Department of Plant Pathology and the Genome Center.

A longtime board member at Nvidia Corp. dumped more than $48 million worth of the chip maker’s shares earlier this week, cashing in on the stock’s recent surge.

Harvey Jones, who has been on the Nvidia NVDA, +2.12% board since 1993, sold nearly of the company Tuesday at prices between $400 and $408.51, according to a filing with the Securities and Exchange Commission made public Wednesday. He pocketed $48.3 million through the transaction, which took place with shares that he held in his living trust.

Intel announced the next step on its road to quantum with the release of its latest quantum chip, a 12-qubit, silicon-based chip the company is calling “Tunnel Falls”. No, no, it’s okay, you can keep those greenbacks in your wallet: Intel isn’t in the commercialization phase yet. Instead, Tunnel Falls is meant to be a research test chip: it’s still a stepping stone towards the actual Quantum Processing Units of the future. Hopefully, those will be more like Intel’s own Tunnel Falls than Iran’s Amazon-based “quantum computing” technology.

“Tunnel Falls is Intel’s most advanced silicon spin qubit chip to date and draws upon the company’s decades of transistor design and manufacturing expertise. The release of the new chip is the next step in Intel’s long-term strategy to build a full-stack commercial quantum computing system. While there are still fundamental questions and challenges that must be solved along the path to a fault-tolerant quantum computer, the academic community can now explore this technology and accelerate research development.” says Jim Clarke, Intel’s director of Quantum Hardware.

While it may be underwhelming to know that Tunnel Falls is just a research test chip, it’s also an often overlooked necessity for any new technology. Before any work can be done within the quantum computers of the future, the algorithms, the learning and the how-to have to be started today. One issue with that is the difficulty in producing quantum computing hardware; there’s a reason such a small number of big companies — from Intel to Microsoft, IBM, IonQ, and Google — are actively developing quantum computing hardware.

Astronomers discovered two runaway stars racing out of our galaxy at speeds 10 times faster than the fastest human-made spacecraft.

Much like artificial intelligence, quantum computing has the potential to transform many industries. But a cybersecurity threat looms large.

Controlling chemical reactions to generate new products is one of the biggest challenges in chemistry. Developments in this area impact industry, for example, by reducing the waste generated in the manufacture of construction materials or by improving the production of catalysts to accelerate chemical reactions.

For this reason, in the field of polariton chemistry—which uses tools of chemistry and quantum optics—in the last 10 years different laboratories around the world have developed experiments in optical cavities to manipulate the chemical reactivity of molecules at room temperature, using electromagnetic fields. Some have succeeded in modifying chemical reactions products in organic compounds, but to date, and without relevant advances in the last two years, no research team has been able to come up with a general physical mechanism to describe the phenomenon and to reproduce it to obtain the same measurements in a consistent manner.

Now a team of researchers from Universidad de Santiago (Chile), part of the Millennium Institute for Research in Optics (MIRO), led by principal investigator Felipe Herrera, and the laboratory of the chemistry division of the US Naval Research Laboratory, (United States), led by researcher Blake Simpkins, for the first time report the manipulation of the formation rate of urethane molecules in a solution contained inside an infrared cavity.

Scientists from a collection of Chinese research institutions collaborated on a study of organ regeneration in mammals, finding deer antler blastema progenitor cells are a possible source of conserved regeneration cells in higher vertebrates. Published in the journal Science, the researchers suggest the findings have applications in clinical bone repair. With the activation of key characteristic genes, it could potentially be used in regenerative medicine for skeletal, long bone or limb regeneration.

Limb and organ regeneration is a long coveted technology in medical science. Humans have some limited regenerative abilities, mostly in our livers. If a portion of the liver is removed, the remaining liver will begin to grow until it reaches its original functional size. Lungs, kidneys, and pancreas can do this also, though not as thoroughly or efficiently.
