Daily Roundup: Robotic Moths, Cancer Battles, Electricity Vending Machines
- All bats aren’t created equal: Using robotic moths, scientists discovered that bats emitting non-stop radar-like calls catch more insects than their intermittent-emitting brethren—and they do this by hearing the “siren-like” echoes of flying bugs. This suggest that bats evolved their echolocation abilities to increase their nightly catch.
- Scientists reported that ovarian cancer survival rates have doubled in the UK in the past 30 years, a changeÂ they attribute to better treatments, such as broader access to chemotherapy.
- Cheetos, Snickers, and electricity: Japanese companies are rolling out the first vending machines capable of charging electric cars, with plans of installing at least 10,000 by the end of the year.
- Laugh your leg ulcers away: After a five-year study discovered that ultrasound—commonly used to treat leg ulcers—was ineffective, lead researcher Andrea Nelson told the BBC, Instead, lead researcher Professor Andrea Nelson said: “The key to care with this group of patients is to stimulate blood flow back up the legs to the hear….[and] “believe it or not, having a really hearty chuckle can help… This is because laughing gets the diaphragm moving and this plays a vital part in moving blood around the body.”
- Tis the season to take more drugs: Researchers discovered that our bodies metabolize drugs at different rates depending on the season (faster in the summer, slower in the winter)—a finding that could lead to modifying prescription drug doses based on the season.
- Good for the criminal, bad for the owner: Engineers have invented a robot that can open any combination lock in under two hour. Hide your money while you can.
