Paris (AFP) — Scientists have developed a human embryo “blueprint” using human stem cells, in a breakthrough that could provide vital insight into the early stages of infant development, new research showed Thursday.

Teams from the University of Cambridge and the Netherlands-based Hubrecht Institute said their model will allow them to observe never-before-seen processes underlying the formation of the human body.

The layout of humans — known as the body plan — happens through a process known as gastrulation, where three distinct layers of cells are formed in the embryo that will later give rise to the body’s three main systems: nervous, musculoskeletal and digestive.

Paris (AFP) — Scientists have observed the fifth state of matter in space for the first time, offering unprecedented insight that could help solve some of the quantum universe’s most intractable conundrums, research showed Thursday.

Bose-Einstein condensates (BECs) — the existence of which was predicted by Albert Einstein and Indian mathematician Satyendra Nath Bose almost a century ago — are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius).

At this point, the atoms become a single entity with quantum properties, wherein each particle also functions as a wave of matter.

“The operation is believed to be the first of its kind in the U.S. The patient, a woman in her 20s, had been healthy, but the coronavirus devastated her lungs.”

A young woman whose lungs were destroyed by the coronavirus received a double lung transplant last week at Northwestern Memorial Hospital in Chicago, the hospital reported on Thursday, the first known lung transplant in the United States for Covid-19.

The 10-hour surgery was more difficult and took several hours longer than most lung transplants because inflammation from the disease had left the woman’s lungs “completely plastered to tissue around them, the heart, the chest wall and diaphragm,” said Dr. Ankit Bharat, the chief of thoracic surgery and surgical director of the lung transplant program at Northwestern Medicine, which includes Northwestern Memorial Hospital, in an interview.

The job market of tomorrow will require people to develop their technical capacity in tandem with human-only skills.

Regeneron Pharmaceuticals announced Thursday that it’s started the first clinical trial of its experimental coronavirus antibody drug.

The antibody cocktail is being tested in four human populations. Two groups of people will receive the drug to test its effectiveness as a treatment for Covid-19; the other two will receive it as a possible prevention.

“We’ll be hopefully to quickly test the safety and then start understanding the efficacy for four major different settings of this virus challenge,” Regeneron’s chief scientific officer, Dr. George Yancopoulos, said on CNBC’s “Squawk Box.” Yancopoulos said he thinks that, “if all goes well,” the company could have “definitive data” within a few months on the effectiveness of the antibody cocktail.

Recent therapeutic trials of “classical” psychedelic drugs, such as psilocybin (from magic mushrooms) or LSD, have reported benefits to wellbeing, depression and anxiety. These effects seem to be linked to a sense of “ego dissolution” — a dissolving of the subjective boundaries between the self and the wider world. However, the neurochemistry behind this effect has been unclear. Now a new paper, published in Neuropsychopharmacology, suggests that changes in brain levels of the neurotransmitter glutamate are key to understanding reports of ego dissolution — and perhaps the therapeutic effects of psychedelics.

Natasha Mason at Maastricht University, the Netherlands, and colleagues recruited 60 participants for their study. All had taken a psychedelic drug before, but not in the three months prior to the study. Half received a placebo and the other half were given a low to moderate dose of psilocybin (0.17 mg/kg of body weight).

The team then used a technique called proton magnetic resonance spectroscopy (MRS) to look at concentrations of glutamate (as well as other neurochemicals) in the medial prefrontal cortex (mPFC) and the hippocampus — two regions that have been implicated as key to the psychedelic drug experience. The team also looked at patterns of “functional connectivity” within networks of brain regions, a measure of how closely correlated brain activity is across those regions. Six hours after taking the drug or placebo, the participants reported on their subjective experiences using two surveys: The 5 Dimensions of Altered States of Consciousness and the Ego Dissolution Inventory.

Many consumers may have heard of blockchain technology, especially in relation to cryptocurrency. However, they may not be aware of its full potential and impact across industries. Blockchain has the potential to simplify and add greater security to data management, and since its inception, this technology has quietly been changing business processes.

To get further insights, we asked the members of Forbes Technology Council to share some ways blockchain has changed (or will soon change) business. Their best answers are below.

Last week, I wrote about the diversity problem in AI and why we need to fix it. I asked you to tell us about your experiences as a Black person in AI or share the names of Black colleagues you admire. Thank you to everyone who responded. It was heart-warming to hear from so many of you.

Many of you shared your frustration with the lack of mentors who understand your challenges, the alienation of being the only Black face at professional meetings, and the struggle to overcome economic and social inequalities. Black women, especially, wrote about the difficulties of building a career in AI. Some of you described your efforts to support Black people in science and technology and provide tech resources to underserved communities. Thank you for sharing with us your dreams and also your disappointments.

We will feature some of your stories in our Working AI blog series. Please stay tuned.
