Team builds the first living robots

A team of scientists has created the first living robots, 'xenobots', by assembling frog embryo cells into new life forms. These biodegradable organisms can move, heal themselves, and even carry payloads, promising advances in drug delivery, toxic waste clean-up, and more.

Artificial muscle sheets transform stem cells into bone

Researchers have developed a new method to transform stem cells into bone cells using an artificial muscle sheet with shape-memory function. This technology has potential applications in treating complex bone fractures by culturing stem cells on the sheet and adapting them to directly strengthen bones.

New study reveals international movements of Atlantic tarpon, need for protection

A new study by the University of Miami Rosenstiel School revealed that Atlantic tarpon migrate thousands of kilometers in distance beyond U.S. borders. The research found the fish use both freshwater and estuarine habitats throughout their life, with previously unknown spawning locations identified in Florida and the Gulf of Mexico.

Connecting the dots in the migraine brain

Researchers found structural brain connectivity changes between migraine patients and healthy volunteers, as well as between episodic and chronic migraine patients. Strengthening connectivity was observed in areas implicated in migraine's pathophysiology, while weakening connectivity patterns were seen in the temporal lobe of migraine ...

Researchers find minimally invasive procedure to treat chronic Achilles tendon disorder improves patient outcomes and reduces recovery time

Researchers have developed a minimally invasive procedure to treat chronic Achilles tendon disorder, reducing pain and recovery time. The percutaneous Zadek osteotomy (ZO) technique has shown significant improvement in functional outcomes and faster recovery times compared to traditional open surgery.

Children's packed lunches lack nutritional quality

A recent study found that fewer than two in every 100 packed lunches meet nutritional standards, with an increase in vegetables and a decrease in sugary food. The researchers argue that the Government should make fresh vegetables freely available in schools and that the food industry should develop healthier options.

Iodine in the stratosphere

Researchers detected inorganic iodine in the stratosphere at a concentration of 0.77 parts per trillion by volume, suggesting it plays a crucial role in ozone depletion. Iodine emissions from humans may increase particle formation and continue to affect stratospheric ozone levels.
