Climate change drives collapse in marine food webs

Climate change drives collapse in marine food webs
A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine "food webs." Published in the open access journal PLOS Biology, the study's lead author PhD student, Hadayet Ullah…

CRISPR treatment prevents hearing loss in mice

CRISPR treatment prevents hearing loss in mice
Using molecular scissors wrapped in a greasy delivery package, researchers have disrupted a gene variant that leads to deafness in mice. A single treatment involving injection of a genome editing cocktail prevented progressive hearing loss in young animals that would have otherwise gone deaf, Howard Hughes Medical Institute (HHMI) Investigator David Liu and colleagues report…

Origins of photosynthesis in plants dated to 1.25 billion years ago

Origins of photosynthesis in plants dated to 1.25 billion years ago
The world's oldest algae fossils are a billion years old, according to a new analysis by earth scientists at McGill University. Based on this finding, the researchers also estimate that the basis for photosynthesis in today's plants was set in place 1.25 billion years ago. The study, published in the journal Geology, could resolve a long-standing…

New software can verify someone’s identity by their DNA in minutes

New software can verify someone’s identity by their DNA in minutes
In the science-fiction movie Gattaca, visitors only clear security if a blood test and readout of their genetic profile matches the sample on file. Now, cheap DNA sequencers and custom software could make real-time DNA-authentication a reality. Researchers at Columbia University and the New York Genome Center have developed a method to quickly and accurately…

Antibiotics resistance: Researchers succeed to block genes of resistance

Antibiotics resistance: Researchers succeed to block genes of resistance
Antibiotics are commonly used around the world to cure diseases caused by bacteria. But as the World Health Organization and other international bodies have pointed out, the global increase of antibiotic resistance is a rapidly worsening problem. And since antibiotics are also an essential part of modern medicine, as prophylactic treatment during surgeries and cancer…

Sea turtles overcame hurricane and heat to have decent South Florida nesting season

Sea turtles overcame hurricane and heat to have decent South Florida nesting season
Green sea turtles, once served in soup with a splash of sherry, overcame a hurricane and another hot summer to produce a record South Florida nesting season. Sea turtle nesting season officially ended Tuesday, with the suspension of rules restricting beach lighting that could disorient newly hatched turtles. For months, thousands of female greens made nighttime crawls…

Newly discovered nearby planet could support life

Newly discovered nearby planet could support life
You may want to get used to the name Ross 128 b. The newly discovered exoplanet is the second-closest found to our solar system, only 11 light-years away. And it could support life. Announcements about exoplanets, those found outside our solar system, seem almost commonplace in this golden age of discovery for astronomers. So why…

Ancient lizardlike creature bridged gap between land and sea

Ancient lizardlike creature bridged gap between land and sea
This beautifully preserved, nearly complete fossil is shedding new light on the evolution of the aquatic members of a small, enigmatic group of ancient reptiles called pleurosaurs. The bones belong to a new species of pleurosaur whose anatomical features weren’t fully adapted to water, but were on the way to enabling an aquatic lifestyle. The creature (which…
