3. Evolution shifts to off-world human colonies.

4. Transhumanism will drive evolution.

Is natural selection still a major force in human evolution? As far back as high school biology, we’ve been taught to think the answer must be yes. But is it really true?

Is it possible to rapidly increase (or decrease) the amount of information the brain can store?

A new international study led by the Research Institute of the McGill University Health Centre (RI-MUHC) suggests it may be. Their research has identified a molecule that improves brain function and memory recall is improved. Published in the latest issue of Cell Reports, the study has implications for neurodevelopmental and neurodegenerative diseases, such as autism spectrum disorders and Alzheimer’s disease.

I remember questioning this data, as it was not even research on animals, it was observation of people’s medical files.

Three unlikely collaborators are at the heart of the fast-moving COVID-19 research scandal, which led to retractions last week by The Lancet and The New England Journal of Medicine (NEJM), and the withdrawal of an online preprint, after the trove of patient data they all relied on was challenged. The three physician-scientists never were at the same institution nor had they ever before written together, but they are the only authors in common on the disputed papers, and the other co-authors all have ties to at least one of them. Their partnership, which seized a high-impact role during a global public health crisis, has now ended disastrously.

The first author for both retracted papers was cardiac surgeon Mandeep Mehra, an eminent Harvard University professor who works at Brigham and Women’s Hospital (BWH) and is known internationally for cardiovascular medicine and heart transplants. He provided the kind of gravitas that can fast-track papers to leading journals. In a statement provided by BWH, Mehra said he had met another of the trio, cardiac surgeon Amit Patel, in “academic and medical circles,” and that Patel had introduced him to Sapan Desai, a vascular surgeon and founder of Surgisphere, the tiny company that supplied the data. Journal disclosures, however, also indicate Mehra received compensation from Triple-Gene, a gene therapy company Patel co-founded to develop cardiovascular treatments.

Another link on diet/healthspan.

Studies by Monash Biomedicine Discovery Institute (BDI), have provided a new understanding into the roles two essential amino acids play in metabolic health, which may help scientists in the fight against obesity.

Led by Dr. Adam Rose, the recent finding, published in Nature Communications, shows that by reducing the amount of two amino acids —threonine and tryptophan—in young healthy mice, they were able to burn more calories than they consumed, without calorie reduction, keeping them lean and healthy and without the side-effect of lower muscle mass. A low-threonine diet even protected mice that were morbidly obese and prone to developing type 2 diabetes.

Paved roads are nice to look at, but they’re easily damaged and costly to repair. Erik Schlangen demos a new type of porous, asphalt made of simple materials with an astonishing feature: When cracked, it can be “healed” by induction heating. (Filmed at TEDxDelft.)

A Minneapolis manufacturing company whose plant was set on fire by rioters plans to leave the city, saying that city officials afforded them no assistance in handling the destruction.

“They don’t care about my business,” 7-Sigma Inc.’s president and owner, Kris Wyrobek, told The Star Tribune about Minneapolis public officials. “They didn’t protect our people. We were all on our own.”

The 7-Sigma plant in south Minneapolis, which the company has maintained since 1987, shut down several hours early around 7 p.m. instead of 11 p.m. as a precautionary measure on the first night of rioting. The company manufactures several products, including rollers for high-speed printing presses and medical training mannequins.

The personal genomics and biotechnology company 23andMe is perhaps best known for its home DNA testing kits, whereby consumers can learn about their genetic make-up or ancestry.

However, after the COVID-19 outbreak was declared a global pandemic, the company switched gears and looked to see how their gene testing services could offer a helping hand in understanding the disease’s pathophysiology.

One aspect of COVID-19 that has puzzled scientists and clinicians alike is why, when infected with SARS-CoV-2, do some patients display mild to moderate symptoms (or no symptoms at all), whereas other patients develop severe symptoms that can prove fatal?

Their new approach to 3D bioprinting and allows for non-invasive tissue growth and wound healing. It works through injecting bioink cells, the additive material traditionally used in 3D bioprinting, under the skin and using near-infrared light to penetrate the tissue and transfer customizable building designs — like an ear or an abstract shape — to newly injected cells.

The ear began to form in just 20 seconds.

Using a new approach to 3D bioprinting researchers have designed a way to non-invasively grow a wide range of customizable tissue under living skin.

Everyone knows that the great and power omnipresent mushroom that lives across the universe able to survive even in space.

Researchers have elucidated the molecular mechanism of the fungus that turns ants into living zombies. The fungus specifically affects the ants’ neurobiology, odor perception and biological clock. The Utrecht microbiologist Robin Ohm publishes this, together with American and German colleagues, in G3.

The fungus Ophiocordyceps camponoti-floridani can infect ants and manipulate their behavior in a way that is beneficial for fungus growth and transmission. These infected ants are called “zombie ants.” Influenced by the fungus, the ants climb to a high point and bite into a branch, attaching themselves until death. The fungus then digests the ant and forms a fruitbody with which the fungus spreads its spores. The molecular mechanisms behind this behavioral modification are still largely unknown, as in similar parasitic interactions in which the behavior of a host is manipulated.
