Though people often want to share good news as soon as they learn it, a study has found that keeping good news a secret before telling someone else could make people feel more energized and alive.

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.
