Slimming down a colossal fossil whale
A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Older African elephants will be most severely affected by the changing climate
Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
New tool helps decipher gene behavior
Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact in diseases. This research has partly focused on 'epigenetic marks', which are chemical modifications to DNA, RNA, and the associated proteins (known as histones).
Study finds drought fuels invasive species after wildfires
Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Chemistry in the ground affects how many offspring wild animals have
Chemistry in the ground affect how many kids wild animals have Areas with more copper and selenium in the ground lead to higher reproductive success in wild musk oxen in Greenland.
Change in gene code may explain how human ancestors lost tails
A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
New discovery shows how cells defend themselves during stressful situations
A recent study has unveiled an exciting discovery about how our cells defend themselves during stressful situations. The research shows that a tiny modification in the genetic material, called ac4C, acts as a crucial defender, helping cells create protective storage units known as stress granules. These stress granules safeguard important genetic instructions when the cell is facing challenges. The new findings could help shed light on relevant molecular pathways that could be targeted in disease.
Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins
Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.
Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Human stem cells coaxed to mimic the very early central nervous system
The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists.
Butterflies mimic each other's flight behavior to avoid predators
Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being eaten.
Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog
Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.
Blindness from some inherited eye diseases may be caused by gut bacteria
Sight loss in certain inherited eye diseases may be caused by gut bacteria, and is potentially treatable by antimicrobials, finds a new study in mice.
