Cells

Scientists are conducting a long-term experiment on evolution to investigate how single-celled organisms could evolve into multicellular lifeforms. After thousands of generations, their yeast grew 20,000 times bigger and 10,000 times tougher.

Cancer is the end result of a wide range of problems, and learning how it occurs is key to prevention and treatment. Now, scientists have discovered a never-before-seen cancer-causing mechanism – a kind of clog in a cellular garbage disposal system.

Three times more men than women develop mouth and throat cancers, most likely caused by HPV, the world's most common STI. There's a vaccine that can prevent 90% of these HPV-related cancers, however it's mainly women getting the shots.

Scientists at UC San Diego have developed a way to potentially slow down the cellular aging process, using an oscillating genetic 'clock.' In tests, yeast cells were found to live significantly longer than those without.

Researchers have created a micro-robot the size of a single biological cell that navigates using both electricity and magnetic fields and can identify and capture a single cell, opening the door to a vast array of applications.

Scientists have made a breakthrough towards an off-the-shelf treatment for immunotherapy against cancer. A synthetic protein tweak can allow immune cells from any donor to be given to any patient without the risk of a dangerous immune reaction.

Scientists have long known that the engine room of cells, the mitochondria, play an essential role in the growth of cancer. Now, they have the clearest picture yet of just how the energy organelles form complex structures within lung cancer tumors.

Nearly 20,000 women will receive an ovarian cancer diagnosis in 2023. But new findings into how resilient cells help neighbor cells also resist chemotherapy may lead to more effective treatment of a disease that has a recurrence rate of more than 70%.

Scientists have developed a new type of cancer vaccine that shows promise in clearing out leukemia in mice. The technique involves reprogramming cancer cells into immune cells so that they can teach the immune system how to fight off the disease.

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.

An international team of scientists has found a way to regenerate kidneys damaged by disease, restoring function and preventing kidney failure. The discovery could help improve treatments for complications stemming from diabetes and other diseases.

Our ancestors probably didn’t smell good, but did they smell well? A new study has grown odor receptors from Neanderthals and Denisovans, and tested their sensitivities to different smells compared to modern humans.
