A California company says its experimental blood test was able to detect many types of cancer at an early stage and gave very few false alarms in a study that included people with and without the disease.
Grail Inc. gave results in a news release on Friday and will report them Saturday at the American Society of Clinical Oncology meeting in Chicago. They have not been published in a journal or reviewed by other scientists.
Many companies are trying to develop early detection “liquid biopsy” tests that capture bits of DNA that cancer cells shed into blood.
Machines are mastering vision and language, but one sense they’re lagging behind on is touch. Now researchers have created a sensor-laden glove for just $10 and recorded the most comprehensive tactile dataset to date, which can be used to train machine learning algorithms to feel the world around them.
Dexterity would be an incredibly useful skill for robots to master, opening up new applications everywhere from hospitals to our homes. And they’ve been coming along in leaps and strides in their ability to manipulate objects, OpenAI’s cube juggling robotic hand being a particularly impressive example.
So far, though, they’ve had one hand tied behind their backs. Most approaches have relied on using either visual data or demonstrations to show machines how they should grasp objects. But if you look at how humans learn to manipulate objects, you realize that’s just one part of the puzzle.
Researchers have determined that gum disease (gingivitis) plays a decisive role in whether a person develops Alzheimer´s or not.
“We discovered DNA-based proof that the bacteria causing gingivitis can move from the mouth to the brain,” says researcher Piotr Mydel at Broegelmanns Research Laboratory, Department of Clinical Science, University of Bergen (UiB).
The bacteria produces a protein that destroys nerve cells in the brain, which in turn leads to loss of memory and ultimately, Alzheimer´s.
The researchers of a new publication take a look at the effects of obesity on aging and consider its impact in the context of the Hallmarks of Aging, a popular theory that breaks down aging into nine distinct processes.
The case for obesity accelerating aging
Being overweight and carrying excessive amounts of visceral fat, a type of body fat that is stored in the abdominal cavity and surrounds a number of important internal organs, such as the liver, pancreas, and intestines, is known to increase the risk of age-related diseases.
We are pleased to announce the launch of the Longevity Book Club hosted by LEAF Director Javier Noris, where you can join other longevity enthusiasts in reading the most interesting works that relate to our mission of ending age-related diseases.
You will also get the opportunity to listen to discussion panels and take part in Q&A sessions that are focused on books that touch on these important scientific, philosophical, moral and futuristic longevity topics. This is the ideal place to meet like-minded longevity enthusiasts who are working on building their knowledge on longevity and all of the implications that come with ending age-related diseases.
Biologist, Tyrone Hayes is a soft-spoken professor at the University of California with a big message. One of the most commonly used pesticides in agriculture, atrazine, is responsible for feminizing amphibians, according to his research. More importantly, the chemical is effectively eliminating male chromosomes at an alarming rate, at levels which are three times lower than what are currently appearing in our drinking water. It isn’t just lead and fluoride we need to be concerned about, but a known endocrine disruptor, created by Syngenta, that is utterly changing our gene pool.
Hayes has been fighting Syngenta, to report the harmful effects of Atrazine for decades now. His scientific papers describe how Atrazine demasculinizes male gonads producing testicular lesions associated with reduced germ cell numbers in teleost fish, amphibians, reptiles, and mammals, and induces partial and/or complete feminization in fish, amphibians, and reptiles. These effects are strong (statistically significant), consistent across vertebrate classes, and specific. Reductions in androgen levels and the induction of estrogen synthesis — demonstrated in fish, amphibians, reptiles, and mammals — represent plausible and coherent mechanisms that explain these effects.

Ira Pastor comments:
The global economic cost of diabetes was estimated in 2018 to be over US$750 billion.
Type 1 diabetes (T1D), is a form of diabetes in which very little or no insulin is produced by the pancreas. While the cause of type 1 diabetes is still unknown.
Type 2 diabetes (T2D) involves insulin resistance, a condition in which cells fail to respond to insulin properly.
In the “Automate the Freight” series, I’ve concentrated on stories that reflect my premise that the killer app for self-driving vehicles will not be private passenger cars, but will more likely be the mundane but necessary task of toting things from place to place. The economics of replacing thousands of salary-drawing and benefit-requiring humans in the logistics chain are greatly favored compared to the profits to be made by providing a convenient and safe commuting experience to individuals. Advances made in automating deliveries will eventually trickle down to the consumer market, but it’ll be the freight carriers that drive innovation.
While I’ve concentrated on self-driving freight vehicles, there are other aspects to automating the supply chain that I’ve touched on in this series, from UAV-delivered blood and medical supplies to the potential for automating the last hundred feet of home delivery with curb-to-door robots. But automation of the other end of the supply chain holds a lot of promise too, both for advancing technology and disrupting the entire logistics field. This time around: automated packaging lines, or how the stuff you buy online gets picked and wrapped for shipping without ever being touched by human hands.
