South Australian algal bloom species the world's most toxic harmful microalga yet recorded
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.
Storms impact the architecture of webs and the survival of spiders
In the dense forests of the Ecuadorian Andes, the survival of a spider relies not only on its ability to prey on insects but also on its capacity to resist a threat coming from the skies. A new study revealed that the heavy rainfall that hits the region acts as an "ecological fil

New beetle genus named after One Piece's Monkey D. Luffy, encompassing two new species
A research team from the Natural History Museum of Denmark has published a compelling new study in insect taxonomy in the open-access journal ZooKeys, officially establishing a new genus of rove beetle: Luffy gen. nov. The inspiration for the name comes directly from Monkey D. Lu
Hawaiʻi island spinner dolphins are producing fewer calves
Unexpectedly low calf numbers within the spinner dolphin population off Hawaiʻi Island were revealed in a study led by scientists with the Marine Mammal Research Program (MMRP) at the University of Hawaiʻi at Mānoa, along with national and international collaborators. Their resea
Simple cell migration mechanism may explain how hair follicles organize before birth
Simple cell migration mechanism may explain how hair follicles organize before birth
In mammals, hair follicles emerge during embryonic development, forming geometric patterns that vary from one species to another. But how is the position of each hair determined? A team from the University of Geneva (UNIGE) has shown that a simple mechanism based on the movement

They're here: Biologists identify first established colonies of invasive clam in northeast
A collaborative team of biologists led by the University of Massachusetts Amherst, MIT Sea Grant at the Massachusetts Institute of Technology and the Center for Coastal Studies has discovered that the invasive Manila clam, Ruditapes philippinarum, has established itself along the
Bumblebees collect up to 7 times more toxic metals than honeybees
Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.
UK waters hit with extreme heatwave as global sea temperatures reach record levels
Experts warn that some marine species are at risk of ‘mass mortality events’ in ever-warming oceansUK waters are being hit with an “extreme” marine heatwave, the Met Office has said, as scientists warn that high ocean temperatures globally could result in “mass-mortality events”
Tiny Jurassic bird reveals a key step in bird evolution
Tiny Jurassic bird reveals a key step in bird evolution
The transition from a lumbering, heavy dinosaur body to the flight-adapted bird body plan is one of many fascinating episodes in evolutionary history. Working out how this massive transformation took place relies heavily on fossil records, especially of transitional species. A st
