Cells

Scientists have engineered a hybrid mouse with a gene that predates all animal life. The team replaced a single gene in the mouse stem cells with a version from an ancient, single-celled ancestor, and successfully grew healthy live mice from it.

The hugely ambitious project of mapping the estimated 37.2 trillion cells of the human body is close to reaching a historic milestone – the first draft of the 'atlas.' We got a glimpse at what's in store from this unprecedented biological guidebook.

On November 11, MAPHEUS-15 became the 600th suborbital rocket launched from Sweden’s Esrange Space Center. While not wanting to downplay this impressive milestone, many are keener to see whether its payload paid off, scientifically speaking.

Memories can form outside of the brain, according to new research. Non-brain cells exposed to chemical pulses similar to the ones that brain cells are exposed to when presented with new information caused the non-brain cells to switch on a gene critical for memory formation.

Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from sunlight like plants. The breakthrough could have major benefits for growing organs and tissues for transplant, or lab-grown meat.

For 50 years now, camera company Nikon has been highlighting microscopic marvels with the annual Nikon Small World photomicrography competition. Headlining this year’s winners is a groundbreaking view of mouse brain tumor cells.

Microscopic battles rage around and in us at all times, involving surprisingly exciting weapons. Scientists have now observed a bacterium that attacks like a pirate ship, ensnaring its prey with grappling hooks and firing “cannons” that blow it open.

Imagine being horribly maimed and the only way to survive was to merge your damaged flesh with another injured human. Scientists have discovered this startling ability in comb jellies, which can fuse together to share a nervous and digestive system.

In a move akin to puncturing an egg yolk without breaking the shell or egg white, researchers have figured out how to pierce the nucleus of a cell without hurting the rest of the structure. The breakthrough could be big news for medical treatments.

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

A patient with type 1 diabetes has been functionally cured of the disease, requiring no insulin doses for over a year. The treatment involves growing and transplanting new insulin-producing cells from the patient’s own stem cells.

T cells are our first line of defense against cancer, but the battle tends to exhaust them. Now, scientists have found a way to give them extra “batteries” to keep them fighting longer, with promising early results in mice.
