World-largest petawatt laser completed, delivering 2,000 trillion watts output

Posted by in categories: biotech/medical, mobile phones, nuclear energy, quantum physics, security

Circa 2015 In theory this big bang laser could eventually create complex matter but would need to be pocket-size as I want it on a smartphone to make a replicator so I can make fruit or food in space 😀


The Institute of Laser Engineering (ILE), Osaka University, has succeeded to reinforce the Petawatt laser “LFEX” to deliver up to 2000 trillion watts in the duration of one trillionth of one second (this corresponds to 1000 times the integrated electric power consumed in the world). By using this high-power laser, it is now possible to generate all of the high-energy quantum beams (electrons, ions, gamma ray, neutron, positron). Owing to such quantum beams with large current, we can make a big step forward not only for creating new fundamental technologies such as medical applications and non-destructive inspection of social infrastructures to contribute to our future life of longevity, safety, and security, but also for realization of laser fusion energy triggered by fast ignition.

Researcher introduces new CRISPR 3.0 system for highly efficient gene activation in plants

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

In a study in Nature Plants, Yiping Qi, associate professor of Plant Science at the University of Maryland (UMD), introduces a new and improved CRISPR 3.0 system in plants, focusing on gene activation instead of traditional gene editing. This third generation CRISPR system focuses on multiplexed gene activation, meaning that it can boost the function of multiple genes simultaneously. According to the researchers, this system boasts four to six times the activation capacity of current state-of-the-art CRISPR technology, demonstrating high accuracy and efficiency in up to seven genes at once. While CRISPR is more often known for its gene editing capabilities that can knock out genes that are undesirable, activating genes to gain functionality is essential to creating better plants and crops for the future.

“While my lab has produced systems for simultaneous gene editing [multiplexed editing] before, editing is mostly about generating loss of function to improve the crop,” explains Qi. “But if you think about it, that strategy is finite, because there aren’t endless genes that you can turn off and actually still gain something valuable. Logically, it is a very limited way to engineer and breed better traits, whereas the plant may have already evolved to have different pathways, defense mechanisms, and traits that just need a boost. Through activation, you can really uplift pathways or enhance existing capacity, even achieve a novel function. Instead of shutting things down, you can take advantage of the functionality already there in the genome and enhance what you know is useful.”

In his new paper, Qi and his team validated the CRISPR 3.0 system in rice, tomatoes, and Arabidopsis (the most popular model plant species, commonly known as rockcress). The team showed that it is possible to simultaneously activate many kinds of genes, including faster flowering to speed up the breeding process. But this is just one of the many advantages of multiplexed activation, says Qi.

Meat Grown in Israeli Bioreactors Is Coming to American Diners

Posted by in categories: biotech/medical, futurism

Other companies, including BlueNalu Inc., Upside Foods Inc. and Eat Just, have expressed an intention to sell cell-based products in the U.S. Like them, Future Meat must get approval from the U.S. Department of Agriculture and the Food and Drug Administration before offering its products to the public. Kshuk is optimistic, though reaching price parity with conventional meat will probably take the nascent industry a few years.


An Israeli startup wants to replace chicken coops, barns and slaughterhouses with bioreactors to churn out cell-based meat for American diners.

Future Meat Technologies Ltd. is in talks with U.S. regulators to start offering its products in restaurants by the end of next year. The company has just opened what it calls the world’s first industrial cellular meat facility, which will be able to produce 500 kilograms (1102 pounds) a day.

Researchers create an artificial tactile skin that mimics human tactile recognition processes

Posted by in categories: biotech/medical, cyborgs, robotics/AI

Over the past few decades, roboticists and computer scientists have developed artificial systems that replicate biological functions and human abilities in increasingly realistic ways. This includes artificial intelligence systems, as well as sensors that can capture various types of sensory data.

When trying to understand properties of objects and how to grasp them or handle them, humans often rely on their sense of touch. Artificial sensing systems that replicate human touch can thus be of great value, as they could enable the development of better performing and more responsive robots or prosthetic limbs.

Researchers at Sungkyunkwan University and Hanyang University in South Korea have recently created an artificial tactile sensing system that mimics the way in which humans recognize objects in their surroundings via their sense of touch. This system, presented in a paper published in Nature Electronics, uses to capture data associated with the tactile properties of objects.

Scientists may need to rethink which genes control aging

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

To better understand the role of bacteria in health and disease, National Institutes of Health researchers fed fruit flies antibiotics and monitored the lifetime activity of hundreds of genes that scientists have traditionally thought control aging. To their surprise, the antibiotics not only extended the lives of the flies but also dramatically changed the activity of many of these genes. Their results suggested that only about 30% of the genes traditionally associated with aging set an animal’s internal clock while the rest reflect the body’s response to bacteria.

“For decades scientists have been developing a hit list of common aging . These genes are thought to control the aging process throughout the , from worms to mice to humans,” said Edward Giniger, Ph.D., senior investigator, at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) and the senior author of the study published in iScience. “We were shocked to find that only about 30% of these genes may be directly involved in the aging process. We hope that these results will help medical researchers better understand the forces that underlie several age-related disorders.”

The results happened by accident. Dr. Giniger’s team studies the genetics of aging in a type of fruit fly called Drosophila. Previously, the team showed how a hyperactive immune system may play a critical role in the neural damage that underlies several aging brain disorders. However, that study did not examine the role that bacteria may have in this process.

Pathogenic gut bacteria linked to weight loss from low-calorie diet

Posted by in categories: biotech/medical, food

The same bacteria that cause inflammation also trigger weight loss.


A new study investigating how a low-calorie diet alters gut microbial populations is reporting unexpected results. The findings reveal a strange relationship between extreme caloric restriction and increased levels of a pathogenic bacteria linked to inflammatory bowel disease.

The research began by recruiting 80 overweight or obese subjects. Half the cohort were directed to maintain a stable weight for 16 weeks, while the other half completed a medically supervised weight-loss program including eight weeks of a very low calorie diet (800 kcal per day).
