Senescent cells refer to those that have stopped dividing but do not die. They damage nearby healthy cells by releasing chemicals that cause inflammation.

The team identified a protein found in senescent cells in humans and mice and created a peptide vaccine based on an amino acid that constitutes the protein.

The vaccine enables the body to create antibodies that attach themselves to senescent cells, which are removed by white blood cells that adhere to the antibodies.

The earliest genetic traces of Native American ancestry among Polynesians.

The peopling of Polynesia was a stunning achievement: Beginning around 800 C.E., audacious Polynesian navigators in double-hulled sailing canoes used the stars and their knowledge of the waves to discover specks of land separated by thousands of kilometers of open ocean. Within just a few centuries, they had populated most of the Pacific Ocean’s far-flung islands. Now, researchers have used modern DNA samples to trace the exploration in detail, working out what order the islands were settled in and dating each new landfall to within a few decades.

“The whole question of the settlement of Polynesia has been going on for 200 years,” says University of Hawaii, Manoa, archaeologist Patrick Kirch, who was not involved in the research. “This is a really great paper, and I’m happy to see it.”

Over the past few years, different techniques have made it possible to improve the viewing angles of the cameras, taking advantage of extra functionalities such as lasers. This technology allows the device to track objects moving around corners, even when they are completely obscured from view. The device could be used for search-and-rescue missions or installed on cars to detect incoming vehicles.

Now, researchers at the Stanford Computational Imaging Lab have developed a novel method called non-line-of-sight imaging, or keyhole imaging, that allows you to scan an entire room by simply pointing a laser through the keyhole. A single point of laser light entering a room can be used to see what physical objects might be inside.

What’s New: In its relentless pursuit of Moore’s Law, Intel is unveiling key packaging, transistor and quantum physics breakthroughs fundamental to advancing and accelerating computing well into the next decade. At IEEE International Electron Devices Meeting (IEDM) 2021, Intel outlined its path toward more than 10x interconnect density improvement in packaging with hybrid bonding, 30% to 50% area improvement in transistor scaling, major breakthroughs in new power and memory technologies, and new concepts in physics that may one day revolutionize computing.

“At Intel, the research and innovation necessary for advancing Moore’s Law never stops. Our Components Research Group is sharing key research breakthroughs at IEDM 2021 in bringing revolutionary process and packaging technologies to meet the insatiable demand for powerful computing that our industry and society depend on. This is the result of our best scientists’ and engineers’ tireless work. They continue to be at the forefront of innovations for continuing Moore’s Law.” –Robert Chau, Intel Senior Fellow and general manager of Components Research

Why It Matters: Moore’s Law has been tracking innovations in computing that meet the demands of every technology generation from mainframes to mobile phones. This evolution is continuing today as we move into a new era of computing with unlimited data and artificial intelligence.

And some of the genetic programming for this regenerative superpower may have been passed down to humans.

Chinese scientists have developed a targeted delivery system that can bring gene-editing tools to colon cells, offering a precise cure for inflammatory bowel disease.

The study, published on Thursday in the journal Science Advances, reported a CRISPR-Cas9 prodrug nanosystem that can transport a gene-editing protein exclusively to inflammatory lesions in mice colons and then “switch on” the protein.

More specifically, the diffractive pupil mirror pattern spreads starlight into a complex flower pattern. This makes it easier to show the fine detail needed to detect the small wobbles a planet would make in the star’s motion.

TOLIMAN fills an important niche in the study of exoplanets, searching for them around the very nearest stars. As has been noted, that task has actually been more difficult, so far, than finding planets around more distant stars. TOLIMAN will focus on detecting these worlds, if they are there. What will it find?

Bottom line: A new custom-designed space telescope mission called TOLIMAN will search for nearby habitable planets in the closest star system to Earth, Alpha Centauri.

Engineered Arts, a robotics firm located in the United Kingdom, released a video showing a humanoid robot that looks exceptionally lifelike — and suddenly the science fiction movie I, Robot is trending.

The company named their robot Ameca, but Ameca’s hyper-realistic expressions and motions look eerily like Sonny, the fictional android (played by actor Alan Tudyk) who co-starred with Will Smith in the film. It may be a coincidence, or it’s one more example of science fiction inspiring real life tech.

In the Engineered Arts video, the grey-faced humanoid robot wakes up, makes a surprised expression, and then examines its own hands as if it also can’t believe how real it looks. The company calls Ameca “the world’s most sophisticated human-shaped robot” — which may be self-promoting, but perhaps not underserved, based on that video.
