Reducing their natural signals: How sneaky germs hide from ants

Science Daily - 02/02/2023
Not only humans are social, ants are too. Group members are taking care of sick ones by providing collective hygiene measures. This presents germs with a task. They must circumvent the immunity of an individual ant and avoid the group's healthcare. A new study reveals that germs develop a sneaky way to escape the ant colony's defense systems by reducing their detection cues.

ChatGPT helps streamline routine tasks, but don’t expect it to do all the heavy lifting in all areas in its present state. It might not be the best tool for the job if you’re looking to dive deep into a topic or solve a complex problem

New research turns what we know about bird window strikes inside-out

Science Daily - 02/02/2023
New research reveals that decals intended to reduce incidents of bird window strikes -- one of the largest human-made causes of bird mortality -- are only effective if decals are placed on the outside of the window. Researchers found that the patterns on the films and decals placed on the internal surface of windows do not reduce collision because they may not be sufficiently visible to birds.

Science Daily - 02/02/2023
A new study shows that both social isolation and loneliness are associated with higher rates of heart failure but whether or not a person feels lonely is more important in determining risk than if they are actually alone.

Antidepressants used for chronic pain on the rise, but are they effective?

Science Daily - 02/02/2023
New research has found some antidepressants may be effective in treating certain chronic pain conditions, but others lack convincing evidence on their effectiveness.

A quasiparticle that can transfer heat under electrical control

Science Daily - 02/02/2023
Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.

Engineers examine drinking water management strategies

Science Daily - 02/02/2023
While residents in California are still dealing with damage from last month's floods -- after years of devastating droughts -- engineers are looking at better ways to manage the delivery of safe drinking water to homes. Things to consider include a changing climate, costs and sustainability.
