Researchers from South Korea have engineered a strain of bacteria that infiltrates tumors and fools the body’s immune system into attacking cancer cells. In experiments, the modified bacteria worked to reduce cancer in mice, raising hope for human trials.
Speculation has emerged in recent years that young blood can reverse the aging process, raising the prospect of an exciting new rejuvenation technique. A new study contradicts this claim, pointing to other factors that may be responsible for the perceived anti-aging effects of youthful blood.
Using skin cells extracted from mice, researchers in Japan have produced fully functional egg cells that were used to produce healthy mouse pups. Should the method work in humans, it could introduce powerful new ways of treating infertility—and even allow same-sex couples to produce biological offspring.
This year’s Nobel Prize in Physiology or Medicine has been awarded to Japan’s Yoshinori Ohsumi for furthering our understanding of autophagy, the biological process wherein the body eats some of itself in order to survive.
A new microscope developed at the Marine Biological Laboratory in Woods Hole, Massachusetts is allowing scientists track the position and orientation of individual molecules in living cells. It has the potential to reveal unknown aspects of molecular behavior, including those that turn cells into agents of disease.
Researchers from the University of Washington are the first to visualize the insidious way that the flu virus latches onto a cell and plows its way inside, causing an infection.
Scientists say a groundbreaking fertility treatment to correct potentially harmful genetic mutations has the potential to backfire, recreating the exact mutation the intervention was meant to fix. It’s a problem that could put an immediate halt to the pending practice—but a work-around may be possible.
Scientists have sustained human embryos in a petri dish for 13 days, shattering the previous record of nine days. The breakthrough will allow researchers to study early fetal development in unprecedented detail, and brings us one step closer to viable “artificial wombs.” But it’s adding fuel to an already heated…
Using state-of-the art microscopy, scientists have peered inside cardiac cells while they beat, revealing tube-like structures that buckle and then snap back into shape, much like shock absorbers. The details now appear in Science.
For the first time ever, molecular biologists have filmed the death of a human white blood cell. But the video shows something else, too. These integral components of our immune system do not go quietly into that good night. Rather, they go down alerting their neighbors to the presence of potential pathogens.
For the first time ever, researchers in New Zealand have shown that mitochondrial DNA can move between cells in an animal tumor. It's an extraordinary finding that could lead to an entirely new field of synthetic biology and the treatment of hundreds of diseases.
Researchers at Berkeley have orchestrated the flow of cell groups by using electrical currents. It's a tissue engineering breakthrough that could eventually lead to "smart bandages" that use electricity to guide cells during the wound healing process.
The 2013 Nobel Prize in Physiology or Medicine has been awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof "for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells".
A new five-year pilot study has shown that lifestyle changes, like an improved diet, exercise, and stress management, may help reverse aging processes at the cellular level. But as exciting as this finding is, we’re still far from the proverbial fountain of youth.
No, this isn't something out of an Octavia Butler novel. It’s Tetrahymena thermophila — a single-celled organism that goes way beyond male and female. It has seven different sexes to choose from. Now a new study published in PLOS has finally made sense of its bizarrely complex and seemingly random sex life.
Researchers at the Pasteur Institute in Paris have discovered that certain stem cells can stay alive in human corpses for at least 17 days after that person is declared dead. What were we saying the other day about the difficulty with defining death?
It's one of the biggest milestones for stem cells since their discovery. Researchers yesterday published the first results of a clinical trial where doctors transplanted of stem cells into the eyes of patients suffering from a form of progressive blindness. And the preliminary results look very good.
Researchers have known for some time that women who experience weakened heart function in the months before and after childbirth (a condition known as peripartum cardiomyopathy) recover more quickly than any other group of heart failure patients. Now, a team of researchers from Mt. Sinai School of Medicine thinks it…
Scientists have known for some time that dogfish sharks, like the one pictured up top, naturally produce a broad-spectrum antibiotic called squalamine in their livers. Now, new research into the cellular function of squalamine reveals how it also confers a broad-spectrum antiviral benefit for the shark — one we humans…
Injuries to parts of the nervous system — the spinal cord, for example — are among the most devastating that human beings can sustain. But the recent discovery of a new class of spinal cord cell could soon lead to novel therapies capable of regenerating parts of the central nervous system.
