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.

How does a virus hijack insect sperm to control disease vectors and pests?      (via sciencedaily.com)     Original source 

A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.

Scientists raise the alarm: Too many harbour porpoises die each year in fishing nets      (via sciencedaily.com)     Original source 

In order to keep the population of harbour porpoises in Danish coastal waters stable, only 24 can perish in fishing nets each year. However, over 900 die each year.

Baby quasars: Growing supermassive black holes      (via sciencedaily.com)     Original source 

The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.

The sweet stuff: How insects tell sugars apart      (via sciencedaily.com)     Original source 

Whereas humans have one receptor on their tongues that can detect all sorts of sweet things, from real sugar to artificial sweeteners like aspartame, insects have many receptors that each detect specific types of sugars. Researchers have now uncovered one way insect receptors are able to be so selective, an insight they say will help us understand how animals decipher the chemical world and how we might mimic that ability in the future.

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.

Scientists CT scanned thousands of natural history specimens, which you can access for free      (via sciencedaily.com)     Original source 

Natural history museums have entered a new stage of scientific discovery and accessibility with the completion of openVertebrate (oVert), a five-year collaborative project among 18 institutions to create 3D reconstructions of vertebrate specimens and make them freely available online.

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.

Lab-grown liver organoid to speed up turtle research, making useful traits easier to harness      (via sciencedaily.com)     Original source 

Researchers developed protocols for growing organoids that mimic a turtle liver, the first organoids developed for a turtle and only the second for any reptile. The discovery will aid deeper study of turtle genetics, including the cause of traits with potential medical applications for humans such as the ability to survive weeks without oxygen.

Conservation actions for SA's white shark population now a matter of urgency      (via sciencedaily.com)     Original source 

A group of marine biologists specializing in shark ecology, genetics and fisheries have challenged the findings from a recent study suggesting that South Africa's white shark population has not decreased, but simply redistributed eastwards to flee predation from orcas.

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.
