You don't need to be very altruistic to stop an epidemic (medicalxpress.com)

Reducing social contact is widely understood to slow disease spread, but because there is no personal health benefit gained from self-isolating, this would seem to require some concern for others. But how much do you have to care about others before you would choose to self-isolate when sick? Even people who are only barely altruistic still choose to self-isolate when infected, suggesting it may be a natural survival strategy, finds a new University of Warwick-led study.

Finding the honey bee dance floor: New method shows how it moves within the hive (phys.org)

When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or water relative to the sun. For years, scientists had a vague understanding of where this occurred in the hive, generally describing it as near the entrance. But in a new paper published in the journal PLOS One, researchers have developed a mathematical method to pinpoint the exact boundaries and shape of the region where this form of communication occurs, an area known as the dance floor.

New medical imaging technology can aid bone removal in cochlear implant surgery (medicalxpress.com)

Cochlear implant surgery helps people with severe hearing loss by placing an electronic device inside the inner ear. To reach the inner ear, surgeons must first remove part of a bone behind the ear, in a procedure called mastoidectomy. The shape of this surgically created cavity varies from patient to patient and has no clear outer boundary, making it difficult to anticipate using traditional image-analysis tools. Better prediction of this shape before surgery could support navigation systems, robotic tools, and improved visualization for surgeons, along with better outcomes for patients.

Curiosity rover captures Martian spiderwebs up close (phys.org)

For about six months, NASA's Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the red planet later than scientists expected. This possibility raises new questions about how long microbial life could have survived on Mars billions of years ago, before rivers and lakes dried up and left a freezing desert world behind.

A heatshield for 'never-wet' surfaces: Engineers repel even near-boiling water with low-cost, scalable coating (techxplore.com)

Superhydrophobic surfaces—those famously "never-wet" materials that make water bead up and roll away—have a stubborn weakness: hot water. Once temperatures climb above roughly 40 degrees Celsius, many superhydrophobic coatings abruptly lose their magic. Instead of skittering off, hot droplets start sticking, soaking into the surface texture and leaving behind wet patches and residue.
