Physics of snakeskin sheds light on sidewinding

Researchers discovered that sidewinders' bellies have tiny pits and few spikes, which enhances sidewinding but is not as efficient for forward undulation. The study provides insights into convergent evolution and could lead to improvements in human technology, such as snake robots for search-and-rescue missions.

Could robots for sex, friendship improve our aging society?

A new paper argues that robots designed for older adults can provide essential human values like social interaction, emotional fulfillment, and bodily integrity. The author suggests that Western cultures' narrow view of sex as lust needs to be challenged, and that robots can enable people to experience physical affection and self-respect.

Microscopic robots 'walk' thanks to laser tech

The new microscopic robots are controlled by flashing laser pulses and can walk thanks to a simple circuit made from silicon photovoltaics. The researchers explored ways to enhance the robots with more complicated electronics and onboard computation, potentially leading to swarms of tiny robots crawling through human tissue and blood.

Don't forget to clean robotic support pets, study says

A new study found that robotic support pets for older adults and people with dementia acquire bacteria over time, posing a risk of illness. However, a simple cleaning procedure involving anti-bacterial products and wipes can effectively reduce microbial loads to safe levels.
