Outside of expensive transplants and drugs with questionable effectiveness, a proper treatment has continued to elude the great number of scientists working in the realm of hair loss. But sources of optimism are never far away, the latest coming out of Japan’s Yokohama National University where scientists have developed an improved technique they claim brings higher rates of follicle growth and could be scaled up to cover larger, vaster expanses more efficiently.
For several years now, we’ve been hearing about “microneedle patches” that deliver medication less painfully and more safely than hypodermic needles. A new take on the technology may allow them to work even better, by copying the structure of venomous snakes’ fangs.
Our bodies do a decent enough job of repairing themselves, able to patch up wounds, fight off infections and even heal broken bones. But that only applies up to a certain point – lose a limb, for example, and it’s not coming back short of a prosthesis. Other creatures have mastered this skill though, and now scientists at the University of California Davis (UC Davis) and Harvard have sequenced the RNA transcripts for the immortal hydra and figured out how it manages to do just that.
(repeat) Are you ready to defer all your personal decision-making to machines? Polls show that most Americans are uneasy about the unchecked growth of artificial intelligence. The possible misuse of genetic engineering also makes us anxious. We all have a stake in the responsible development of science and technology, but fortunately, science fiction films can help.
The movies Ex Machina and Jurassic Park suggest where A.I. and unfettered gene-tinkering could lead. But even less popular sci-fi movies can help us imagine unsettling scenarios regarding over-population, smart drugs, and human cloning.
And not all tales are grim. The 1951 film, The Man in the White Suit, weaves a humorous story of materials science run amok.
While in its early stages, bioprinting of human tissue is an emerging technology that is opening up some exciting possibilities, including the potential to one day 3D print entire human organs. This scientific objective has now grown a little bit closer, with researchers at Carnegie Mellon University reporting a breakthrough that enabled the printing of full-scale heart components that in some cases functioned similarly to the real thing.
An exciting new study, led by scientists from King’s College London, has discovered a new type of cell in the liver. The research describes the cell as having “stem cell-like properties,” with the potential to regenerate damaged liver cells and treat disease in the organ without the need for a transplant.
Tech billionaire Peter Thiel painted a gloomy picture of artificial intelligence in his NYT’s op-ed on Thursday, detailing the technology’s real value and purpose as primarily a military one.
“The first users of the machine learning tools being created today will be generals,” Thiel declared in his 1,200-word piece. “A.I. is a military technology.”
Thiel’s portrayal is a far cry from the optimistic view that many in Silicon Valley have embraced. Artificial intelligence has promised to give us the next, best Netflix recommendations, let us search the internet using our voices, and do away with humans behind the wheel. It’s also expected to have a huge impact in medicine and agriculture. But instead, Thiel says that AI’s real home is on the battlefield — whether that be in the physical or cyber worlds.
SELF-RENEWAL Fluorescent markers reveal which genes are turned on as hydras’ stem cells develop into specific cell types. For instance, nerve cells light up magenta in one hydra (second from left). Another (second from right) shows gene activity behind two of the stages of development (early, green; late, red) of the animal’s stinging cells.
In the deep of the ocean, where the sun’s rays struggle to penetrate, organisms lurk that could solve the biggest medical crisis facing humanity.
Far below the surface bacteria are engaged in warfare with each other — and to do so they make an antibiotic so strong it can destroy the toughest superbugs in our hospitals.
“But there’s a problem,” Rebecca Goss, a professor of organic chemistry at the University of St Andrews, said. “It disintegrates in sunlight.”
