CRISPR-edited rice plants increase grain yield

Posted by in categories: biotech/medical, food, genetics

Scientists from Purdue University and the Chinese Academy of Sciences report the use of CRISPR/Cas9 to develop a variety of rice producing 25–31% more grain than traditional breeding methods.

crispr future technology

The team, led by Jian-Kang Zhu, a distinguished professor in the Department of Horticulture and Landscape Architecture at Purdue and director of the Shanghai Center for Plant Stress Biology at the Chinese Academy of Sciences, made mutations to 13 genes associated with the plant hormone abscisic acid – known to play roles in plant stress tolerance and suppression of growth. Of several varieties created, one produced a plant that had little change in stress tolerance but produced 25% more grain in a field test in Shanghai, China, and 31% more in a field test conducted on China’s Hainan Island.

We’re not prepared for the genetic revolution that’s coming

Genetics is influencing more and more of our decisions, but we can’t make the right choices if we don’t understand it.

Weed-killing robots are threatening giant chemical companies’ business models

Posted by in categories: business, food, genetics, robotics/AI

But if robots kill weeds, who will spray Roundup on everything.


AI-powered weed hunters could soon reduce the need for herbicides and genetically modified crops.

How it’s done now: Current farming methods involve spraying large amounts of indiscriminate weed killer over fields full of crops that have been genetically tweaked (usually by the same company that makes the weed killer) to resist the chemicals. The pesticide and seed industry is enormous, worth $100 billion globally. Of that, herbicide sales alone account for $26 billion.

Swallowable ‘bacteria on a chip’ could help diagnose colon cancer, bowel disorders and gut ulcers

Posted by in categories: biotech/medical, computing, genetics, health

Unlike other ingestible chips, this new version by MIT contains millions of genetically engineered living cells to act as sensors, designed to light up when they detect bleeding.

It’s the latest advance in a growing field of sensors that can be swallowed or worn to monitor our health.

Pills equipped with cameras, thermometers and acidity gauges already look for disease and track digestion.

Blocking anti-aging enzymes makes cancer die of old age

Posted by in categories: biotech/medical, genetics, life extension

At the cellular level, aging and cancer are two sides of the same coin. The mechanism that limits a cell’s lifespan can be slowed down, but that can turn them cancerous, as they divide unchecked. Now, scientists at EPFL have found a way to manipulate that mechanism to effectively turn off cancer’s immortality, letting it die slowly and naturally.

Every time a cell divides, it consults the blueprints contained in the chromosomes, but some genetic information is lost with every division. To protect the important bits, the tips of the chromosomes are covered with repeating sequences of “junk” DNA known as telomeres. Eventually even they erode away, leaving the cell vulnerable to damage – which we recognize as wrinkles, grey hairs, decreased metabolism, and higher chances of disease. In that way, telomere length is inextricably linked to aging.

Selfish Ledger: Google’s mass sociology experiment

Posted by in categories: big data, complex systems, DNA, ethics, evolution, genetics, information science, internet, surveillance

Check out the internal Google film, “The Selfish Ledger”. This probably wasn’t meant to slip onto a public web server, and so I have embedded a backup copy below. Ping me if it disappears. I will locate a permanent URL.

This 8½ minute video is a lot deeper—and possibly more insipid—than it appears. Nick Foster may be the Anti-Christ, or perhaps the most brilliant sociologist of modern times. It depends on your vantage point, and your belief in the potential of user controls and cat-in-bag containment.

He talks of a species propelling itself toward “desirable goals” by cataloging, data mining, and analyzing the past behavior of peers and ancestors—and then using that data to improve the experience of each user’s future and perhaps even their future generations. But, is he referring to shared goals across cultures, sexes and incomes? Who controls the algorithms and the goal filters?! Is Google the judge, arbiter and God?

Scientists Kick Off Synthetic Biology Project to Make Virus-Resistant Super Cells

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

Recently, roughly 200 eminent scientists assembled in Boston. Their agenda? Creating “superhero” human cells impervious to all viral attacks and possibly other killers—radiation, freezing, aging, or even cancer.

The trick isn’t super-soldier serum. Instead, the team is relying on tools from synthetic biology to read the cell’s genetic blueprint and rewrite large chunks of the genome to unlock these superpowers.

“There is very strong reason to believe that we can produce cells that would be completely resistant to all known viruses,” said Dr. Jef Boeke, a geneticist at New York University and a co-leader of the project. “It should also be possible to engineer other traits, including resistance to prions and cancer.”

Key part of human gene activation revealed by new study

Posted by in categories: biotech/medical, genetics

May 15 (UPI) — Until now, scientists weren’t sure how gene activation mechanisms avoided nucleosomes, the bodyguards tasked with keeping DNA turned off.

Researchers at the University of California, San Diego, however, have pinpointed a key factor responsible for unraveling nucleosome structures and allowing genes to be activated.

Geneticists described the newly identified nucleosome destabilizing factor, or NDF, this week in the journal Genes and Development.
