A research team has developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room temperature, preventing accidental needle stick injuries and unethical multiple use of needle. A thin-film temperature sensor can be embedded with this needle, enabling real-time monitoring of the patient's core body temperature, or detection of unintended fluid leakage, during IV medication.

Researchers used chiral (twisted) magnets as their computational medium and found that, by applying an external magnetic field and changing temperature, the physical properties of these materials could be adapted to suit different machine-learning tasks.

For years, researchers and clinicians have known that lupus, an autoimmune condition, occurs in women at a rate nine times higher than in men. Some of the factors that cause the disease's high prevalence in women have eluded discovery, but in a new study investigating the immune system processes in lupus and the X chromosome, researchers have uncovered answers about the disease's frequency in females.
