A team of researchers affiliated with several institutions in France has found that amyloid fibrils lit with near-infrared radiation emit a dim, near-infrared signal. In their paper published in the journal Nature Photonics, the group describes their study of amyloid fibrils and plaques in mice and humans and what they found.

Amyloid fibrils are tiny structures that self-form in some proteins. When they clump together, they form what are known as plaques. They are associated with the development of neurological diseases such as Alzheimer’s and Parkinson’s disease. Despite years of study, it is still not known what causes them. In this new effort, the researchers sought to learn more about the early stages of fibril development by developing a way to see it happening.

Prior work had shown that when ultraviolet light shines onto tissue-containing proteins, the tissue emits blue light. Researchers have found that the emissions become stronger if there are fibrils present in the proteins. While this finding has been useful, it has only allowed for superficial study of formation due to the shallow depth of UV and penetration. In their experiments, the researchers tried firing near-field radiation at sample human proteins and found that and fibrils present would emit a dim, near-infrared signal. This was important, because unlike UV light, near-field radiation can penetrate relatively deeply into tissue.

If you are a working, American adult, the 2 TR3Bs you see in this video are your taxpayer dollars floating around. That is technology that Americans have paid for but nearly everyone does not even know it exists, let alone benefit from it.

The TR-3B or also called “Black Manta” is a top-secret black project aircraft of the US Air Force. There is a lot of evidence for the TR-3B. Multiple sightings have been reported e.g. over Antelope Valley, a desert in California. This desert is well-known for the testing of “black project”-related aircraft. It is in close proximity of several military research centers, such as Edwards Air Force Base and Area 42.


Researchers at the Icahn School of Medicine at Mount Sinai have demonstrated that stem cells derived from the placenta known as Cdx2 cells can regenerate healthy heart cells after heart attacks in animal models. The findings, published in the May 20 issue of Proceedings of the National Academy of Sciences (PNAS), may represent a novel treatment for regenerating the heart and other organs.

“Cdx2 cells have historically been thought to only generate the placenta in early embryonic development, but never before were shown to have the ability to regenerate other organs, which is why this is so exciting. These findings may also pave the way to regenerative therapy of other organs besides the heart,” said principal investigator Hina Chaudhry, MD, Director of Cardiovascular Regenerative Medicine at the Icahn School of Medicine at Mount Sinai. “They almost seem like a super-charged population of , in that they can target the site of an injury and travel directly to the injury through the and are able to avoid rejection by the host .”

This team of Mount Sinai researchers had previously discovered that a mixed population of mouse placental stem cells can help the hearts of pregnant female mice recover after an injury that could otherwise lead to . In that study, they showed that the placental stem cells migrated to the mother’s heart and directly to the site of the heart injury. The stem cells then programmed themselves as beating heart cells to help the repair process.

It’s long been known that cannabis plants are indigenous to Central Asia, but a new study provides a fresh focus on where exactly this genus may have first evolved millions of years ago.

Documents dating back to the middle ages show humans have been hypothesising about the geographical origins of cannabis for over a thousand years now, with the famed Arab polymath Ibn Wahshiyya suggesting India or perhaps China as far back as 930 CE.

But the rarity of print fossils (impressions of leaves made on other objects) in the historical record has made it difficult for the research community to identify anything more specific than Central Asia, even with the booming popularity of cannabis currently ongoing in many fields of academic and scientific enquiry.

Robot bees are no replacement for our vital pollinators here on Earth. Up on the International Space Station, however, robots bearing the bee name could help spacefaring humans save precious time.

On Friday, NASA astronaut Anne McClain took one of the trio of Astrobees out for a spin. Bumble and its companion Honey both arrived on the ISS a month ago, and are currently going through a series of checks. Bumble passed the first hurdle when McClain manually flew it around the Japanese Experiment Module. Bumble took photos of the module which will be used to make a map for all the Astrobees, guiding them as they begin their tests there.

The three cube-shaped robots (Queen will arrive from Earth in the SpaceX resupply mission this July) don’t look anything like their namesakes, but they are non-threatening by design, says Astrobee project manager Maria Bualat. Since they’re built to fly around autonomously, doing tasks for the crew of the International Space Station, “one of our hardest problems is actually dealing with safety concerns,” she says.
