Phys.org / Metamorphosis in newts proves costly, with one sex paying a heavier price
Metamorphosis, that profound transformation enabling certain animals to shift between habitats such as from an aquatic to a terrestrial environment, is generally viewed in terms of its benefits. A team of researchers from ...
Phys.org / Why infected stink bugs lift their wings: Hidden parasite escape caught on camera
Male strepsipterans develop inside a host insect during their larval stage and, upon reaching the adult stage, emerge from the host body to begin a free-living phase. In a new study, researchers at University of Tsukuba directly ...
Phys.org / Scientists split gentoo penguins into four species, one totally new to science
The four-foot-tall Emperor penguin of Antarctica may be the most iconic member of this unique family of birds, but 17 other species of penguins populate the Southern Hemisphere, many of them confined to isolated islands that ...
Phys.org / Lab-evolved cyanobacteria survive minute-by-minute light swings, offering clues to hardier crops
Plant scientist Dario Leister and his team are investigating how cyanobacteria adapt to rapidly changing light intensities. This could help optimize photosynthesis in crops. Photosynthesis is one of the most complex processes ...
Phys.org / Plants survived the dinosaur-killing asteroid by duplicating genomes, study suggests
When an asteroid as big as Mount Everest struck Earth 66 million years ago, it wiped out all non-avian dinosaurs and roughly a third of life on the planet. But many plants survived the devastation. In a new study published ...
Phys.org / Nanoparticles overcome drug-resistant cancer via sequential drug release and photothermal therapy
Cancer cells frequently develop the ability to expel anticancer drugs before they can work—a phenomenon called multidrug resistance (MDR)—which is one of the leading reasons why chemotherapy fails in patients. Research published ...
Phys.org / Nearly 3,000 peer-reviewed medical papers have fake citations, AI-assisted audit finds
A new Columbia University School of Nursing AI-assisted audit reveals nearly 3,000 peer-reviewed medical papers have fake citations that do not exist in scientific databases. The results highlight an alarming trend in academic ...
Phys.org / How a strange fruit fly became a bloodthirsty underwater hunter
A carnivorous fruit fly living in bubbling African streams may sound like a fever dream. However, with the help of DNA analysis of a pinned insect from a museum in Zurich, researchers have managed to draw an evolutionary ...
Phys.org / How Dante's Inferno modeled a planetary impact 500 years before modern science
New research reveals that Dante Alighieri's Inferno wasn't just a masterpiece of literature: it was a gedankenexperiment in impact physics. From multi-ring craters to shockwaves that reshaped the globe, discover how a 14th-century ...
Phys.org / This anti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA—a system called CRISPR that's become indispensable to gene editing. But viruses can fight back with a molecular trick that stops the scissors ...
Phys.org / One fifth of flowering plant evolutionary history is at risk of extinction, experts warn
In a new study published in the journal Science, researchers from the Royal Botanic Gardens, Kew, ZSL (Zoological Society of London) and their international collaborators including Boise State University present the first ...
Phys.org / Oceans near record heat again as El Niño conditions begin to build
The European Union's climate monitor said Friday that ocean temperatures are edging toward record highs as conditions shift toward a potentially powerful El Niño weather pattern.
