A sterile solution: How Crispr could protect wild salmon

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

Upon an otherwise unruly landscape of choppy sea and craggy peaks, the salmon farms that dot many of Norway’s remote fjords impose a neat geometry. The circular pens are placid on the surface, but hold thousands of churning fish, separated by only a net from their wild counterparts. And that is precisely the conundrum. Although the pens help ensure the salmon’s welfare by mimicking the fish’s natural habitat, they also sometimes allow fish to escape, a problem for both the farm and the environment.

In an attempt to prevent escaped fish from interbreeding with their wild counterparts and threatening the latter’s genetic diversity, molecular biologist Anna Wargelius and her team at the Institute of Marine Research in Norway have spent years working on ways to induce sterility in Atlantic salmon. Farmed salmon that cannot reproduce, after all, pose no threat to the gene pool of wild stocks, and Wargelius has successfully developed a technique that uses the gene-editing technology Crispr to prevent the development of the cells that would otherwise generate functioning sex organs.

Converting tamarind shells into an energy source for vehicles

Posted by in categories: energy, food, sustainability

Shells of tamarind, a tropical fruit consumed worldwide, are discarded during food production. As they are bulky, tamarind shells take up a considerable amount of space in landfills where they are disposed as agricultural waste.

However, a team of international scientists led by Nanyang Technological University, Singapore (NTU Singapore) has found a way to deal with the problem. By processing the tamarind shells which are rich in carbon, the scientists converted the waste material into carbon nanosheets, which are a key component of supercapacitors — energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.

The study reflects NTU’s commitment to address humanity’s grand challenges on sustainability as part of its 2025 strategic plan, which seeks to accelerate the translation of research discoveries into innovations that mitigate our impact on the environment.

Solectrac launches new 70 HP, 60 kWh electric tractor for $75,000

Posted by in categories: food, sustainability

Electric tractor developer Solectrac has announced that its e70N tractor is now available for sale. Solectrac recently delivered the 70-horsepower, diesel-equivalent tractors to three farms in Northern California as part of a grant from the Bay Area Air Quality Management District’s Funding Agriculture Replacement Measures for Emission Reductions Demonstration Program (FARMER).

Solectrac is an electric tractor developer founded in Northern California with the goal of offering farmers independence from the pollution, infrastructure, and price volatility associated with fossil fuels.

Electrek first reported on Solectrac after it donated a Compact Electric Tractor (CET) to Jack Johnson’s nonprofit organization in Oahu, Hawaii.

Cognitive decline: Investigating dietary factors

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

A great beginning, but more research is needed.


While there are treatments for temporarily alleviating the symptoms of dementia, there is currently no cure available. The search is therefore on to identify lifestyle factors, such as diet, that can reduce individuals’ risk of developing the condition.

Previous research into possible links between eating foods rich in flavonoids and reduced risk of cognitive decline later in life has been inconclusive, however.

I’m sorry Dave I’m afraid I invented that: Australian court finds AI systems can be recognised under patent law

Posted by in categories: food, law, robotics/AI

The applications claimed Dabus, which is made up of artificial neural networks, invented an emergency warning light and a type of food container, among other inventions.

Several countries, including Australia, had rejected the applications, stating a human must be named the inventor. The decision by the Australian deputy commissioner of patents in February this year found that although “inventor” was not defined in the Patents Act when it was written in 1991 it would have been understood to mean natural persons – with machines being tools that could be used by inventors.

But in a federal court judgment on Friday, justice Jonathan Beach overturned the decision, and sent the matter back to the commission for reconsideration.

Centenarians have unique gut bacteria that enables them to live longer

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

TOKYO — Centenarians have unique gut bacteria that enables them to live to a ripe old age, according to new research. Scientists in Japan say this unique gut makeup fuels bile acids that protect against disease.

The discovery could lead to yogurts and other probiotic foods that increase longevity.

“In people over the age of 100, an enrichment in a distinct set of gut microbes generate unique bile acids,” says lead author Professor Kenya Honda of Keio University in a statement per South West News Service. “They might inhibit the growth of pathogens.”

Austin’s Silicon Labs sells business unit for $2.75 billion, shifts focus to Internet of Things

Posted by in categories: business, computing, food, internet, security

Austin-based Silicon Labs has sold its infrastructure and automotive business for $2.75 billion to California-based semiconductor maker Skyworks Solutions. Plans for the all-cash deal was initially announced in April.

Silicon Labs primarily designs semiconductors and other silicon devices. CEO Tyson Tuttle said the deal will allow the company to focus on its growing Internet of Things business. Internet of Things, or IoT as it is known in industry shorthand, refers to a range of non-computing devices —from kitchen devices to security systems — that connect to the Internet.

Silcon Labs’ IoT business already serves tens of thousands of customers and works in thousands of applications, but the deal narrows Silicon Labs focus exclusively to that technology.

Small proteins discovered to be regulators of the aging process

Posted by in categories: food, life extension

Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process. Ubiquitin was previously known to control processes such as signal transduction and metabolism. Prof. Dr. David Vilchez and his colleagues at the CECAD Cluster of Excellence for Aging Research at the University of Cologne performed a comprehensive quantitative analysis of ubiquitin signatures during aging in the model organism Caenorhabditis elegans, a nematode worm broadly used for aging research. This method—called ubiquitin proteomics—measures all changes in ubiquitination of proteins in the cell.

The resulting data provide site-specific information and define quantitative changes in changes across all proteins in a cell during aging. A comparison with the total content of a cell (proteome) showed which changes have functional consequences in protein turnover and actual protein content during aging. The scientists thus discovered new regulators of lifespan and provide a comprehensive dataset that helps to understand aging and . The article, “Rewiring of the ubiquitinated proteome determines aging in C. elegans,” has now been published in Nature.

“Our study of ubiquitin changes led us to a number of exciting conclusions with important insights for understanding the aging process,” said Dr. Seda Koyuncu, lead author of the study. “We discovered that aging leads to changes in the ubiquitination of thousands of proteins in the cell, whereas longevity measures such as reduced food intake and reduced insulin signaling prevent these changes.” Specifically, the researchers found that aging causes a general loss of ubiquitination. This is caused by the enzymes that remove ubiquitin from proteins become more active during aging. Normally, ubiquitinated proteins are recognized and destroyed by the proteasome, the cell’s garbage truck. The scientists showed that the longevity of organisms is determined by age-related changes in the degradation of structural and regulatory proteins by the proteasome.
