Good for him.

A new company launched Monday by former NASA chief Dan Goldin aims to deliver a major boost to the field of neural computing.

KnuEdge’s debut comes after 10 years in stealth; formerly it was called Intellisis. Now, along with its launch, it’s introducing two products focused on neural computing: KnuVerse, software that focuses on military-grade voice recognition and authentication, and KnuPath, a processor designed to offer a new architecture for neural computing.

BOSTON, June 3 (UPI) — Until now, synthetic biological systems have focused exclusively on either analog or digital computation. Researchers at MIT have devised a technique for creating cellular gene circuits capable of complex computation.

Analog computation, also called continuous computation, is the type of processing happening as the human eye adjusts to changing light conditions. Digital computation involves binary decision making, on or off processes.

The new synthetic cellular circuitry designed by MIT scientists performs like a comparator, receiving analog input signals and converting them into digital output signals.

Future genetic engineering may create animals that can photosynthesize like plants. These animals would require less food because they will make some of it from sunlight. In principle, even humans could be modified this way!

There are already some natural cases of animal-plant integration. Some marine flatworms have algae living in their translucent bodies,between their cells. Increasing the degree of plant-animal integration further, the method used by coral and various other marine animals is to have symbiotic algae living, not between their cells (like the flatworms), but actually inside some of their cells. The algae are typically of the genus Symbiodinium, and live in “symbiosomes,” blobs inside the animal cells that hold the algae separate from the rest of the cell. Each symbiosome is a kind of really, really tiny terrarium (a “nanoterrarium”) maintained by the finely engineered nanotechnology device of nature we call the cell. The cells supply the algae, in its symbiosome home, with basic chemicals and exposure to light. In return the algae produce nutrients that the animals extract from the symbiosome and use. In coral, when these algae die the coral loses color and, if not reversed, itself dies in the phenomenon called “coral bleaching.”

Not surprised;

A long line of research links poverty and depression. Now, a study by Duke University scientists shows how biology might underlie the depression experienced by high-risk adolescents whose families are socio-economically disadvantaged.

The study, published May 24, 2016 in the journal Molecular Psychiatry, combined genetics, brain imaging and behavioral data gathered as adolescents were followed for more than three years as part of a larger study.

Sea urchins are remarkable organisms. They can quickly regrow damaged spines and feet. Some species also live to extraordinary old ages and—even more remarkably—do so with no signs of poor health, such as a decline in regenerative capacity or an increase in age-related mortality. These ocean Methuselahs even reproduce as if they were still youngsters.

MDI Biological Laboratory Associate Professor James A. Coffman, Ph.D., is studying the regenerative capacity of sea urchins in hopes that a deeper understanding of the process of regeneration, which governs the regeneration of aging tissues as well as lost or damaged body parts, will lead to a deeper understanding of the aging process in humans, with whom sea urchins share a close genetic relationship.

In a paper recently published in Aging Cell, a leading journal in the field of aging biology, with Andrea G. Bodnar, Ph.D., of the Bermuda Institute of Ocean Studies, the scientists shed new light on the aging process in sea urchins, raising the prospect that the physical decline that typically accompanies aging is not inevitable.

The oldest space dust yet found on Earth suggests that the ancient atmosphere of Earth had significantly more oxygen than previously thought, a new study finds.

Although oxygen gas currently makes up about one-fifth of Earth’s air, there was at least 100,000 times less oxygen in the primordial atmosphere, researchers say. Oxygen easily reacts with other molecules, which means it readily gets bound to other elements and pulled from the atmosphere.

Previous research suggests that significant levels of oxygen gas started permanently building up in the atmosphere with the Great Oxidation Event, which occurred about 2.4 billion years ago. This event was most likely caused by cyanobacteria — microbes that, like plants, photosynthesize and release oxygen. [Infographic: Earth’s Atmosphere Top to Bottom].

According to established scientific knowledge, complex cells (called eukaryotic cells) can’t survive without mitochondria — tiny organelles that control respiration and power movement and growth. You can think of them as tiny batteries converting energy so that cells can go about their business, but they perform other key jobs, too. They are, as the common adage goes, the powerhouse of the cell.

Now, scientists working in Canada and the Czech Republic have made a surprising discovery: a eukaryotic cell without these mitochondrial batteries. It’s an unprecedented find that’s likely to change our thinking about how some types of cells can exist and grow. In other words, life is more flexible than we thought.

“[Mitochondria] were considered to be absolutely indispensable components of the eukaryotic cell and the hallmark of the eukaryotic cell,” team leader, Anna Karnkowska from the University of British Columbia told Nell Greenfieldboyce at NPR.
