A new computer-trained scent model has done better than humans at identifying odors. In analyzing 500,000 potential odor molecules that had never before been synthesized, it also handily did work that would take 70 person-years to complete.

While completing an important task with other distraction such as TV can seem like it’s a battle of willpower, scientists have discovered how it's not you but your brain that keeps you on the right track. Or at least it tries to.

Memory is commonly affected following a traumatic brain injury. A new study has found that AI-guided electrical brain stimulation in people with moderate-to-severe traumatic brain injury may successfully treat their memory loss.

It's cheap, easy to transport, effective and non-invasive. Scientists have had their eye on genetically modified lettuce for insulin delivery for a while now (we're as surprised as you are), but it's one step closer after this promising animal trial.

Researchers have just found a bacteria that forms superstructures when it gets caught in sticky traps made by other bacteria, helping it erode enamel and form cavities. The finding could lead to new ways to keep our teeth clear of the invaders.

Bad news, there's no magic pill for weight loss just yet. The good news? Scientists have uncovered the workings of a protein that triggers calorie burning in brown fat, and they believe it gets us one step closer to being able to 'switch on' fat loss.

Researchers have developed a highly efficient new gene-editing method that uses virus-based protein fragments. The method could be used to level up existing cell and gene therapies used to treat cancer and other diseases.

Scientists have identified the role an enzyme, crucial to the body’s metabolism, plays in the development of kidney disease, opening the door to new methods of prevention and treatment of this increasingly prevalent condition.

If you needed more motivation to brush your teeth, this could do the trick. Scientists have discovered that cavity-causing bacteria and fungi in saliva can team up to form “superorganisms” that can sprout limbs to crawl and even leap across teeth.

Like many menial tasks, there may soon be a way to outsource brushing your teeth to robots. A new system of microrobots can change shape to form bristles or floss, and don’t just brush plaque away but release antimicrobials to kill bad bacteria.

A powerful new optical chip can process almost two billion images per second. The device is made up of a neural network that processes information as light without needing components that slow down traditional computer chips, like memory.

Researchers have discovered a new type of cell in the human lung. Named respiratory airway secretory cells (RASCs), they seem to play a role in regenerating other cells and could be a target for new treatments for lung diseases like COPD.
