Zebrafish navigate to find their comfortable temperature      (via sciencedaily.com)     Original source 

Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.

Clown anemonefish seem to be counting bars and laying down the law      (via sciencedaily.com)     Original source 

We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.

How to run a password update campaign efficiently and with minimal IT costs      (via sciencedaily.com)     Original source 

Computer scientists found that email notifications to update passwords potentially yielded diminishing returns after three messages. They also found that a prompt to update passwords while users were trying to log in was effective for those who had ignored email reminders. Researchers also found that users whose jobs didn't require much computer use struggled the most with the update.

Engineers develop hack to make automotive radar 'hallucinate'      (via sciencedaily.com)     Original source 

Engineers have demonstrated a system they've dubbed 'MadRadar' for fooling automotive radar sensors into believing almost anything is possible. The technology can hide the approach of an existing car, create a phantom car where none exists or even trick the radar into thinking a real car has quickly deviated from its actual course. And it can achieve this feat in the blink of an eye without having any prior knowledge about the specific settings of the victim's radar, making it the most troublesome threat to radar security to date.

Discovery of a third RNA virus linage in extreme environments Jan 17, 2024      (via sciencedaily.com)     Original source 

A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.

Back from the dead: Tropical tree fern repurposes its dead leaves      (via sciencedaily.com)     Original source 

Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.

These male marsupials give up sleep for sex      (via sciencedaily.com)     Original source 

All animals need sleep. When humans or animals don't get enough, it can lead to trouble paying attention, irritability, and other ill effects. In a new study, researchers have made the surprising discovery that a small Australian marsupial called an antechinus will sacrifice hours of sleep per night to make more time for sex during the mating season.
