Every cell in your body runs on a currency called ATP, and the factories that mint it are mitochondria. For decades, ...

The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without sustaining damage from dangerously intense rays. Living on light is a dangerous ...

Overview Energy plans to develop satellites collecting solar power in geosynchronous orbit and beaming it to Earth using near-infrared wide-beam lasers. Credit: Overview Energy WASHINGTON — Overview ...

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Limb ...

Sperm cells are made in the testicles and carry the father's genetic material. A sperm cell has a head, neck, and tail to help it reach and fertilize the egg. Around 300 million sperm are released ...

Let’s say it’s 2036, and scientists are working on a new class of drugs. These medications are mirror-image versions of the molecules your body uses to fight disease. Their big advantage is that ...

Large cell carcinoma is aggressive, requiring early detection through imaging and biopsy for optimal treatment outcomes. Treatment strategies vary by stage, including surgery, chemotherapy, radiation, ...

Overview Energy emerged from stealth today with a plan to use the world’s solar panels as nighttime collectors of power beamed down from space. The startup plans to use large solar arrays in ...

Cell-surface RNAs, including glycoRNAs, have been described, yet their precise composition across primary cell types remains unresolved, in part due to technical challenges in preserving membrane ...

A global consortium of scientists has created the first and most detailed "developmental maps" of the mammalian brain (from mouse to human) to date, taking the first critical steps in unraveling the ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

Professor Indraneel Mittra and his team show that DNA fragments from dying cells function as agents of horizontal gene transfer in mammalian cells. For decades, scientists have known that bacteria can ...
