Rather than bringing people into the lab, researchers at MIT are putting tiny labs into people via a tiny implantable capsule that can track the growth of a tumor or detect heart-deterioration or even silent heart attacks from inside the body.
Using a combination of microscopy methods, Harvard researchers have untangled part of the circuitry of the cerebral cortex, illuminating brain connections in 3-D. A new neural circuit model will allow researchers to crawl through the individual connections in a neural network.
A new type of endoscope with a super-small camera on its end could yield cheap, disposable scopes for peering inside your body. The camera is about the size of a grain of kosher salt, and its designers say it's the smallest camera ever.
A potential new cancer treatment could be as simple as taking a swig of some genetically modified salmonella. The bug, famous for forcing food recalls and making people sick, could be weaponized to fight tumor cells.
Human trials are already under way at the University of Minnesota, where researchers have successfully tested salmonella-led tumor control in mice.
Anyone who has ever donated blood has learned his or her blood type, such as AB, O negative, etc., which will be matched to a recipient with the same blood type. If blood types do not match, a recipient’s immune system could reject the transfusion, a potentially fatal proposition. But a new method masks the type of donated red blood cells, possibly eliminating the need to test types and making it easier to give and receive blood.
European regulators have approved the sale of a new medical implant intended to be a less invasive option than gastric bypasses or stomach stapling procedures: a “gastric pacemaker” for the gut. When a person is eating, a device implanted in the abdomen triggers a premature notion of fullness by stimulating stomach nerves.
Six years ago, researchers at the Wake Forest Institute for Regenerative Medicine used tissue-engineering techniques to grow new urethras for five young male patients from their own cells. Now, an article published in the Lancet has declared the procedure a success. Each of the boys is now in good physical health, with a new urethra that has repaired the defects previously present.
In a major breakthrough for Alzheimer’s research, scientists have turned human embryonic stem cells and skin cells into brain cells associated with memory and learning, whose death is key to the progression of the disease. The finding could help scientists test new ways to keep the cells from dying, and could someday lead to lab-grown stockpiles that could be implanted into the brains of Alzheimer’s patients.
Studying our natural internal bacteria could help doctors cure diseases that affect millions

When Jake Harvey visits the clinical center at the National Institutes of Health in Bethesda, Maryland, he is usually dirty, itchy and wheezing—not the happiest state of affairs for a 14-year-old boy. But his doctors require that for 24 hours prior to each visit, he refrain from bathing, or using the inhaler that soothes his asthma, or applying the ointment that softens his eczema. In order to study his illness, they need him to be in as close to his natural state as possible.
It’s been a big week for the world of the small. In a new microscope breakthrough, researchers have figured out how to use a minuscule sheet of light to produce movies of living cells, revealing mitosis in action and illuminating cells' three-dimensional architecture with the greatest detail ever seen.
