What was once thought to be just one star is actually two. What's more, the two stars are so close that they've broken a record for being the tightest ultracool binary system ever observed, revolving around each other in less than an Earth day.

Mini human brains, grown from stem cells and implanted into living mice, have for the first time been shown to respond to things the mice were seeing. Scientists were able to watch the responses in real time thanks to specialized graphene electrodes.

Engineers have developed an electronic patch capable of monitoring biomolecules in deep tissue, which they say can be used to detect a range of life-threatening conditions, including organ dysfunction and malignant cancers.

Intestinal glucose levels are a major indicator of gastrointestinal health, and the current method of measuring them involves putting a catheter down the patient's throat. Soon, however, a swallowable "smart pill" could do the job less intrusively.

A pair of new studies have reported novel links between fungal microorganisms and cancer. The research reports different types of tumors seem to harbor unique fungal populations, raising the possibility of new ways to diagnose and treat cancer.

Scientists have recently had success in curing mice of a serious type of pneumonia, using what are described as "microrobots." The bots were actually live algae cells, which carried life-saving medication throughout the rodents' lungs.

Respiratory ailments may hamper the body's ability to draw oxygen from the lungs, which is why patients' blood oxygen levels often need to be checked. New research now suggests that people could track those levels at home, using their smartphone.

Scientists at UCSD have built a lithium battery that can not only operate at freezing cold and scorching hot temperatures, but may store double the energy of current devices and be friendlier to the environment while it's at it.

Scientists have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by copying a healthy version from the other. “Nicking” the DNA also seemed to work better than cutting it.

Your smartphone continuously emits Bluetooth Low Energy (BLE) signals, even when it isn't paired to a Bluetooth device. Scientists are now reporting that by analyzing those signals, it could be possible for someone else to track your whereabouts.

Because GPS doesn't work indoors, it can be difficult for robots to determine where they are within a structure. A new system could help, by using a building's existing Wi-Fi access points to guide wheeled or walking robots.

While we've already seen skin-worn patches that can detect individual substances in the bloodstream, a new one goes considerably further. It simultaneously measures glucose, alcohol and lactate, and could have multiple applications.
