New Fillings Can Repair Teeth From the Inside

They stimulate stem cells to regrow dentin: scientists

(Newser) - Imagine a world without root canals. It's possible with what the UK's Royal Society of Chemistry calls "a new paradigm for dental treatments." Scientists at Nottingham and Harvard universities say they've developed dental fillings that stimulate stem cells to regrow and heal damaged teeth. Researcher... More »

Lab-Grown Bones Were Just Successfully Implanted

It's a scientific first

(Newser) - For the first time, scientists have successfully implanted living bone grown in a laboratory, Live Science reports. And while those implants were in miniature pigs, not humans, it's pretty impressive nonetheless. Scientists removed part of the jaw bones of 14 pigs, carved cow thighbones into the right shape, removed... More »

Strong Chemo Plus Stem Cell Transplant May Halt MS

Study used extremely small sample size, but results are encouraging

(Newser) - The sample size was quite small, but research on patients with multiple sclerosis shows promising results on stopping the progression of the incurable disease that causes the immune system to attack the coating around nerve fibers (and the fibers themselves) in the brain and spinal cord, the BBC reports. Per... More »

Goal of Clinical Trial: Reverse Human Death

Researchers hope to revive brains of the clinically dead

(Newser) - Scientists are predicting "the eventual reversal of death in our lifetime," and a new clinical trial could take us one step closer to that goal. The National Institutes of Health has approved "the first trial of its kind" by US biotech company Bioquark to attempt to revive... More »

Working Mouse Sperm Created From Stem Cells

Step could someday lead to treatment for infertile men

(Newser) - Scientists have produced rudimentary mouse sperm from stem cells in the laboratory, a step that may lead to a treatment for infertile men. If the technique pans out in people, doctors might someday be able to turn skin cells from a man into sperm that can pass along his DNA... More »

Researchers Grow Human Ear on a Rat

Technology could someday be used for those born without ears

(Newser) - Cool—and/or creepy—news out of Japan, where researchers at the University of Tokyo and Kyoto University have created a human ear ... on the back of a rat. The researchers used stem cells that grew into ear cartilage, shaping the cells into an ear by putting them in "biological... More »

Most Cancer Types Boil Down to Bad Luck

Study: Heredity and lifestyle play a role in only 1 in 3 cancer types

(Newser) - Roughly two-thirds of cancer types researchers recently studied largely appear to be the result of random mutations and not inherited genes or environmental and lifestyle factors. Reporting in the journal Science , researchers at the Johns Hopkins University School of Medicine investigated 31 common cancer types and found that 22 of... More »

Huge Breakthrough in Quest for Type 1 Diabetes Cure

Scientists have coaxed stem cells into ones that produce insulin in mice

(Newser) - There's no known cure for Type 1 diabetes, so for 3 million Americans, an insulin pump or regular insulin injections form an imperfect and temporary solution. And it's one that doesn't always keep some of the disease's worst outcomes, including blindness and limb amputation, at bay.... More »

Billionaire: I've Reversed the Aging Process

Nygard claims stem cells are making him younger

(Newser) - A Finnish-Canadian billionaire says scientists have found a way to make him younger. Fashion designer Peter Nygard claims he is getting more stem cell treatment than anyone else is currently receiving, and scientists have found "my markers have shown exactly that I have been actually reversing my aging and...

Eyes of the Dead Could Help Living See

Cell transplants restore brain, eye connection

(Newser) - A new technique could dramatically improve the ways in which the eyes of the dead can help restore sight to the blind, according to research published in the journal Stem Cells Translational Medicine . Researchers extracted a type of adult stem cell from the back of donated eyes and found that... More »

Scientists Hail 'Revolutionary' Stem Cell Breakthrough

Scientists find they can make them using blood cells, acid

(Newser) - A new discovery promises to make stem cell research cheaper, faster, and less controversial to boot. Scientists in Japan have shown that stem cells can be created in less than 30 minutes by simply dipping blood cells in acid; the new cells have been dubbed stimulus-triggered acquisition of pluripotency, or...

Study: Teeth Can Be Made From Urine

Chinese scientists managed to grow teeth-like structures

(Newser) - It's a scientific feat equal parts fascinating and stomach-turning: Scientists have been able to grow "rudimentary teeth" from urine, reports the BBC . Suspend your disbelief, and read on: The Chinese team's process, as outlined in Cell Regeneration Journal, had researchers harvest cells from urine and then convert... More »

Human Stem Cells Made From Cloned Embryos

Oregon scientists report breakthrough

(Newser) - Scientists have made a long-sought—and controversial—breakthrough: They created stem cells from cloned human embryos for the first time, reports AP . In theory, the development by researchers at Oregon Health & Science University means that doctors might someday be able to grow tissue from an ailing patient's own... More »

Wanted: 'Adventurous' Woman to Birth Neanderthal

Bringing Neanderthals back could save humanity, geneticist says

(Newser) - A Harvard professor has hatched a plan to bring back the Neanderthals—but he needs an "adventurous" female volunteer to deliver a knuckle-dragging bundle of joy. George Church, a geneticist who helped pioneer the Human Genome Project, says it is now possible to create artificial Neanderthal DNA from bone... More »

Supreme Court Rejects Stem Cell Case

Scientists challenged use of embryonic stem cells; court gives no comment

(Newser) - Federal funding for embryonic stem cell research is safe for now. The Supreme Court won't hear a challenge to the funding, it said today, giving no comment on the matter. "This is good news for patients," said a statement from the Association of American Medical Colleges. "... More »

5-Day-Old Dead People Great for Stem Cells

Bone-marrow cells have a variety of uses

(Newser) - Even after five days, corpses are an excellent source of stem cells to replace fat, cartilage, bone, and other kinds of cells, New Scientist reports. A research team from the University of Miami, Florida, found it could mine mesenchymal stem cells (MSCs) from the bone marrow of finger bones stored... More »

Nobel Prize for Medicine Goes to Stem Cell Scientists

John Gurdon, Shinya Yamanaka share the prize

(Newser) - The first of this year's Nobel prizes was announced this morning, with a British scientist and a Japanese scientist sharing the prize for medicine.
