New study shows how AI can help us better understand global threats to wildlife      (via sciencedaily.com)     Original source 

Researchers used AI to scour information from websites and social media to map bat hunting and trade. Research found evidence of bat exploitation in 22 countries that had not previously been identified by traditional academic research. Following concerns about the reliability of the IUCN Red List, new research demonstrates how AI's ability to filter vast amounts of online data can support wildlife conservation.

Alaska dinosaur tracks reveal a lush, wet environment      (via sciencedaily.com)     Original source 

A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.

Who knew that coprophagy was so vital for birds' survival?      (via sciencedaily.com)     Original source 

New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.

History repeats as Coral Bay faces mass loss of coral and fish life      (via sciencedaily.com)     Original source 

A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.

Maternal obesity may promote liver cancer      (via sciencedaily.com)     Original source 

Obesity, which could reach 50% of the population in certain developed countries by 2030, is a major public health concern. It not only affects the health of those who suffer from it, but could also have serious consequences for their offspring. Scientists have studied the impact of maternal obesity on the risk of developing liver disease and liver cancer. Using an animal model, the team discovered that this risk was indeed much higher in the offspring of mothers suffering from obesity.

Cicadas' unique urination unlocks new understanding of fluid dynamics      (via sciencedaily.com)     Original source 

While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.

New research sets trap for potentially deadly sandfly      (via sciencedaily.com)     Original source 

Scientists have discovered the specific enzyme that a species of sandfly uses to produce a pheromone attractant, which could lead to the creation of targeted traps to control them and reduce the spread of the potentially fatal disease, Leishmaniasis.

New study reveals transgenerational effects of pesticide linuron on frogs      (via sciencedaily.com)     Original source 

Grand-offspring of male frogs exposed to the pesticide linuron exhibited changes in their DNA that was linked to significant physiological impacts, a study reveals. The research highlights the profound transgenerational consequences of environmental pollution on amphibian populations, which are already under threat of extinction.

Natural history specimens have never been so accessible      (via sciencedaily.com)     Original source 

Researchers have painstakingly taken computed topography (CT) scans of more than 13,000 individual specimens to create 3D images of more than half of all the world's animal groups, including mammals, fishes, amphibians and reptiles.

Research sheds light on new strategy to treat infertility      (via sciencedaily.com)     Original source 

New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unable to produce viable eggs due to previous treatment for cancer or other causes. It also raises the possibility of men in same-sex relationships having children who are genetically related to both parents.

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.

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.

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.
