Reptile roadkill reveals new threat to endangered lizard species      (via sciencedaily.com)     Original source 

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.

Interstellar signal linked to aliens was actually just a truck      (via sciencedaily.com)     Original source 

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.

Early life adversity leaves long-term signatures in baboon DNA      (via sciencedaily.com)     Original source 

Early experiences in an animal's life can have a significant impact on its capacity to thrive, even years or decades later, and DNA methylation may help record their effects. In a study of 256 wild baboons, researchers found that resource limitation during early life was associated with many differences in DNA methylation, a small chemical mark on the DNA sequence that can affect gene activity.

Global warming is affecting bats' hibernation      (via sciencedaily.com)     Original source 

Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.

Bee-2-Bee influencing: Bees master complex tasks through social interaction      (via sciencedaily.com)     Original source 

Bumblebees successfully learned a two-step puzzle box task through social observation. This task was too complex for individual bees to learn on their own. Observing trained demonstrator bees performing the first unrewarded step was crucial for successful social learning. Individual bees failed to solve the puzzle without previous demonstration, despite extensive exposure.

Discovery tests theory on cooling of white dwarf stars      (via sciencedaily.com)     Original source 

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.

Do some electric fish sense the world through comrades' auras?      (via sciencedaily.com)     Original source 

It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. Biologists have found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.

Tiny worms tolerate Chornobyl radiation      (via sciencedaily.com)     Original source 

A new study finds that exposure to chronic radiation from Chornobyl has not damaged the genomes of microscopic worms living there today -- which doesn't mean that the region is safe, the scientists caution, but suggests that these worms are exceptionally resilient.

What makes black holes grow and new stars form? Machine learning helps solve the mystery      (via sciencedaily.com)     Original source 

It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
