Frogs Without Legs Regrow Leglike Limbs In New Experiment
An anonymous reader quotes a report from The New York Times: African clawed frogs are masters of putting themselves back together, handily regenerating lost tails and hind limbs, when they are tadpoles. But these powers dim with maturity. Wait for an.....»»
Good news for clumsy divers: Physics holds the key to less-painful belly-flops
Insights could help improve future designs of naval ships, seaplanes, or projectiles. Brown researchers set up a belly flop-like water experiment using a blunt cylinder, adding an important vibrating twist to it that ul.....»»

NASA rocket to see sizzling edge of star-forming supernova
A new sounding rocket mission is headed to space to understand how explosive stellar deaths lay the groundwork for new star systems. The Integral Field Ultraviolet Spectroscopic Experiment, or INFUSE, sounding rocket mission, will launch from the Whi.....»»
When not to reward whistleblowers
The use of whistleblowing to challenge teacher absence in the developing world is worth considering, but its effectiveness can be dampened by offering monetary rewards for reporting absent colleagues, according to a field experiment conducted by Stef.....»»
Research investigates reproductive resource defense in golden rocket frogs
Some things in life are worth fighting for. For animals, the defense of space, known as territoriality, usually functions to safeguard valuable resources like food and mates. However, for a species of tropical frog, researchers have recently discover.....»»
Carl Sagan detected life on Earth 30 years ago—here"s how his experiment is helping us search for alien species today
It's been 30 years since a group of scientists led by Carl Sagan found evidence for life on Earth using data from instruments on board the Nasa Galileo robotic spacecraft. Yes, you read that correctly. Among his many pearls of wisdom, Sagan was famou.....»»
What happens to switchgrass when food reserves are depleted?
As potential for biofuel, switchgrass is a perennial plant that is of great interest to researchers. Scientists from the MSU-DOE Plant Research Laboratory Walker lab are looking at how these plants regrow, even when regrowing with less than its usual.....»»
New study with video shows how female frogs defend themselves against unwanted mating
Among many species, breeding preferences and tactics can differ among males and females. When aggressive behavior by males toward unreceptive females goes awry, it may result in failure to reproduce, and in some cases, fatality for the females involv.....»»
These Gene-Edited Chickens Were Made to Resist Bird Flu
Avian influenza can wipe out entire poultry flocks. An early experiment with Crispr suggests that gene editing can protect chickens against infection......»»
Leap in the dark: On a mission to rescue the Caribbean"s biggest frog
A rescue mission is under way in the Caribbean to save one of the world's largest—and rarest—frogs from extinction......»»
How do caterpillars acquire chubby legs? Scientists trace the origins to a genetic program associated with crabs
Adult insects, including butterflies and moths, typically have only three pairs of legs. But the existence of extra legs in caterpillars—chubby abdominal appendages also known as "prolegs"—has long posed an evolutionary mystery to biologists. A r.....»»
Paint that can change colors? The skin of an octopus holds the key, researchers say
When you think of an octopus, you might be envious of its eight limbs. After all, there's a lot to be done with eight arms. But scientists are a bit more interested in something else: its skin......»»
A Monkey Got a New Kidney From a Pig—and Lived for 2 Years
Human donor kidneys are in short supply. A new experiment that tested gene-edited organ transplants in monkeys showed that pig kidneys may one day be viable substitutes......»»
AI Designs Little Robots in 30 Seconds and They Keep Sprouting Legs
An AI used to build artificial neural networks can also create autonomous robot bodies with remarkable speed .....»»
Female common frogs fake death to get rid of males
A new study shows that, contrary to previous assumptions, female common frogs can reject males and have developed a variety of mate avoidance behaviors to do so. The research was led by Carolin Dittrich and Mark-Oliver Rödel from the Museum für Nat.....»»
The EU Just Kicked Off Its Biggest Climate Experiment Yet
The world’s largest single market has launched a bold plan to tax carbon at its borders. The rest of the world is paying very close attention......»»
Paleontologists find first molecular evidence of ginger pigment molecules in fossil frogs
Paleontologists at University College Cork (UCC) have found the first molecular evidence of pheomelanin, the pigment that produces ginger coloration, in the fossil record......»»
Einstein right again: Antimatter falls “down” due to gravity like ordinary matter
CERN's ALPHA experiment confirms matter and antimatter react to gravity in a similar way. Enlarge / An artist's conceptual rendering of antihydrogen atoms falling out the bottom of the magnetic trap of the ALPHA-g apparatus. (cre.....»»
Chi-Nu experiment ends, bolsters nuclear security and energy reactors
The results of the Chi-Nu physics experiment at Los Alamos National Laboratory have contributed essential, never-before-observed data for enhancing nuclear security applications, understanding criticality safety and designing fast-neutron energy reac.....»»
Despite being properly treated and highly diluted, wastewater still impacts river ecosystem, finds study
An experiment using water from a large wastewater treatment plant (WWTP) carried out by the Stream Ecology group has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly di.....»»
