Researchers have found that opsin 3 -- a protein closely related to rhodopsin, the protein that enables low-light vision -- has a role in adjusting the amount of pigment produced in human skin, a determinant of skin color.
Engineers have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user's skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a flexible, stretchable battery pack and can be embedded in clothing. Researchers say wearing it could help save energy on air conditioning and heating.
For the first time, immunologists have captured on video what happens when T-cells undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allowed for the videos holds promise for the fight against autoimmune disorders such as Type 1 diabetes.
A multidisciplinary team has provided new insight into underlying mechanisms controlling the precise size of cells. The researchers found that 'the adder,' a function that guides cells to grow by a fixed size from birth to division, is controlled by specific proteins that accumulate to a threshold.
Scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation explains more than half of the variation in dog ownership, implying that the choice of getting a dog is heavily influenced by an individual's genetic make-up.
