Chinese scientists have produced a 3D map of an entire rhesus monkey brain, which is 200 times larger than a mouse brain, at a resolution of just 0.001 mm (1 micron).

Seeing the environmental crises rising particularly because of the construction sector, more conscious choices regarding building materials need to be considered. Since the beginning of our craft, architects and constructors have been trying to utilize natural materials in buildings—either used in their raw form, like bamboo, or processed and incorporated into different materials. Hempcrete is one type of concrete incorporating natural materials; it is energy-saving and durable.

SpaceX’s Starship rocket is gearing up for its most ambitious test yet, and CEO Elon Musk has shared images of the rocket stacked up.

Dean’s appearance at TED comes during a time when critics—including current Google employees —are calling for greater scrutiny over big tech’s control over the world’s AI systems. Among those critics was one who spoke right after Dean at TED. Coder Xiaowei R. Wang, creative director of the indie tech magazine Logic, argued for community-led innovations. “Within AI there is only a case for optimism if people and communities can make the case themselves, instead of people like Jeff Dean and companies like Google making the case for them, while shutting down the communities [that] AI for Good is supposed to help,” she said. (AI for Good is a movement that seeks to orient machine learning toward solving the world’s most pressing social equity problems.)

TED curator Chris Andersen and Greg Brockman, co-founder of the AI ethics research group Open AI, also wrestled with the unintended consequences of powerful machine learning systems at the end of the conference. Brockman described a scenario in which humans serve as moral guides to AI. “We can teach the system the values we want, as we would a child,” he said. “It’s an important but subtle point. I think you do need the system to learn a model of the world. If you’re teaching a child, they need to learn what good and bad is.”

There also is room for some gatekeeping to be done once the machines have been taught, Anderson suggested. “One of the key issues to keeping this thing on track is to very carefully pick the people who look at the output of these unsupervised learning systems,” he said.

Since receiving a $25 million grant in 2,019 to become the first National Science Foundation (NSF) Quantum Foundry, UC Santa Barbara researchers affiliated with the foundry have been working to develop materials that can enable quantum information-based technologies for such applications as quantum computing, communications, sensing, and simulation.

They may have done it.

In a new paper, published in the journal Nature Materials, foundry co-director and UCSB materials professor Stephen Wilson and multiple co-authors, including key collaborators at Princeton University, study a new material developed in the Quantum Foundry as a candidate superconductor—a material in which electrical resistance disappears and magnetic fields are expelled—that could be useful in future quantum computation.

Researchers from the group of Hans Clevers (Hubrecht Institute) corrected mutations that cause cystic fibrosis in cultured human stem cells. In collaboration with the UMC Utrecht and Oncode Institute, they used a technique called prime editing to replace the ‘faulty’ piece of DNA with a healthy piece. The study, published in Life Science Alliance on August 9 shows that prime editing is safer than the conventional CRISPR/Cas9 technique. “We have for the first time demonstrated that this technique really works and can be safely applied in human stem cells to correct cystic fibrosis.”

Cystic fibrosis (CF) is one of the most prevalent genetic diseases worldwide and has grave consequences for the patient. The mucus in the lungs, throat and intestines is sticky and thick, which causes blockages in organs. Although treatments are available to dilute the mucus and prevent inflammations, CF is not yet curable. However, a new study from the group of Hans Clevers (Hubrecht Institute) in collaboration with the UMC Utrecht and Oncode Institute offers new hope.

Caffeinated coffee might be protective to overall health, but so is decaf. For example, a 2,019 systematic review published in the Journal of Human Nutrition and Dietetics aiming to “investigate the association of caffeinated and decaffeinated coffee consumption and all-cause mortality” found “similar inverse associations [between] caffeinated coffee and decaffeinated coffee [and all-cause mortality.]”

But is coffee healthy? And do coffee drinkers live longer than non-coffee drinkers?

At the turn of the 20th century, it was considered common knowledge that coffee was unhealthy—there were advertising claims that coffee drinking caused blindness and that “you can recover from any ordinary disease by discontinuing coffee.” And while that may obviously be untrue, there are continuing fears about whether coffee is actually healthy or not. Google receives 4,400 queries a month about” why coffee is bad for you” (for context, “why coffee is good for you” gets only 1,300 queries a month).

For several years, Lu’s lab has been working on ways to use DNA to store information such as memory of cellular events. In 2,014 he and Farzadfard developed a way to employ bacteria as a “genomic tape recorder,” engineering E. coli to store long-term memories of events such as a chemical exposure.

Technique for editing bacterial genomes can record interactions between cells, may offer a way to edit genes in the human microbiome.
