This image taken by the new microscope shows a living bone cancer cell with nucleus (blue), mitochondria (green) and cytoskeleton (magenta).

When you want to look at something small up close, you use a microscope. And when you want to look at something really really small, you use a super-resolution microscope. These tools can look in resolutions of a millionth of a millimeter, but they work slowly due to the volume of image data that they need to record. Now, researchers have developed a way to speed up the process by creating a method which can record data at this microscopic scale in real-time.

Jeanne Loring, director of the Center for Regenerative Medicine at Scripps Research Institute, and her colleagues transplanted a set of cells into the spinal cords of mice that had lost use of their hind limbs to multiple sclerosis. Within a week, as the experimentalists had expected, the mice rejected the cells. But after another week, the mice began to walk.

Increased length of the hippocampus dentate gyrus (DG) for overexpressed TLX gene vs. control group.

City of Hope researchers have found that over-expressing a specific gene could prompt growth in adults of new neurons in the hippocampus, where learning and memory are regulated.

Heptagon Acoustic Tweezer repairs damaged nerves

acoustictweezer

Miniaturized ultrasonic device capable of capturing and moving single cells and tiny living creatures.

University of Glasgow researchers have devised a Heptagon Acoustic Tweezer which makes use of resonance for manipulating matter. This sonic tweezer uses acoustic force to build cell matrices with the possibility of repairing injured nerves.

High-tech glasses help surgeons see cancer

Cancer-detecting-glasses

The glasses are designed to make it easy for surgeons to differentiate cancerous cells from healthy cells.

Researchers at the Washington University School of Medicine have developed high-tech eyewear that helps surgeons detect cancer cells, which glow blue when viewed using the special glasses.

3D printed eye cells could one day cure blindness

Researchers have actually printed viable retina cells using an inkjet printer.

The ability to print up new, living versions of the damaged parts of your body is becoming more viable as a medical procedure, and cuts and scrapes aren’t the only maladies that medical 3D printing can help cure. Living, 3D printed retina cells could someday aid in curing many kinds of blindness.

3D printed human cells could end animal testing within 5 years

3D-printed human tissue could very soon begin saving millions of lives — those of the humble lab mice.

A hundred million animals are killed in labs and classrooms across the U.S. every year.  Many of these mice, rats and rabbits are needed in part to develop the early stages of new vaccines and medicines, which might later go on to treat human illnesses. It is a harsh reality for the animals involved, but one which may be about to change.

Chemotherapy can backfire and cause cancer to grow

Chemotherapy works by inhibiting reproduction of fast-dividing cells such as those found in tumors.

A new study that came out Sunday has found that cancer-busting chemotherapy can cause damage to healthy cells which triggers them to secrete a protein that sustains tumor growth and resistance to further treatment.

World’s oldest fossils could give clues about life on Mars

oldest fossils

This cluster of cells is one example of the spheroidal and ellipsoidal microfossils found at the 3.4-billion-year-old.

Scientists say life thrived on Earth 3.4 billion years ago even though the world still had no oxygen.  But now they say they have the world’s oldest fossils to prove it.
