Advanced microscope shows cells at work in incredible 3D detail

For the first time, scientists have peered into living cells and created videos showing how they function with unprecedented 3D detail. Using a special microscope and new lighting techniques, a team from Harvard and the Howard Hughes Medical Institute captured zebrafish immune cell interactions with unheard-of 3D detail and resolution. The tech has already yielded new insights on cell function and…

NASA team finds massive Everglades mangrove damage from Irma. Can it recover?

Last spring, a team of NASA scientists looking at South Florida's dwindling wetlands flew over the Everglades hoping to use aerial 3D imaging and data from the planet's longest orbiting satellites to plot changes. Then Irma hit. In a matter of hours, about 40 percent of the mangroves were damaged or flattened. The massive toll…

Breakthrough brings gene-editing medicine one step closer to patient applications

Imagine a future where a guided biomachine put into your body seeks out defective gene sequences in each cell and edits in the correct information with precision accuracy. It's called gene editing, and University of Alberta researchers have just published a game-changing study that promises to bring the technology much closer to therapeutic reality. "We've…

New new genus and species of extinct baleen whale identified

University of Otago palaeontologists are rewriting the history of New Zealand's ancient whales by describing a previously unknown genus of baleen whale, alive more than 27.5 million years ago and found in the Hakataramea Valley. The new genus and species of extinct baleen whale is based on a skull and associated bones unearthed from the…

Climate change is transforming the Great Barrier Reef

A new study published online today in Natureshows that corals on the northern Great Barrier Reef experienced a catastrophic die-off following the extended marine heatwave of 2016. "When corals bleach from a heatwave, they can either survive and regain their colour slowly as the temperature drops, or they can die. Averaged across the whole Great Barrier…

Scientists merge statistics, biology to produce important new gene computational tool

The cells in our bodies express themselves in different ways. One cell might put a chunk of genetic code to work, while another cell ignores the same information entirely. Understanding why could spur new stem cell therapies, or lead to a more fundamental understanding of how organisms develop. But zeroing in on these cell-to-cell differences…

A lesson from mating birds: The song gets sweeter over time, a Miami scientist finds

On a dewy summer morning, Karla Rivera-Cáceres, an ornithology researcher at the University of Miami, crouched in her usual workspace –– the tall grasses of Costa Rica’s woodland –– and heard something unusual. Rivera-Cáceres studies bird song, and that day she was listening to the canebrake wren, a brown bird whose bland appearance (it was…

Germs with unusual antibiotic resistance widespread in U.S.

Health departments working with CDC's Antibiotic Resistance (AR) Lab Network found more than 220 instances of germs with "unusual" antibiotic resistance genes in the United States last year, according to a CDC Vital Signs report released today. Germs with unusual resistance include those that cannot be killed by all or most antibiotics, are uncommon in a geographic…

Mutating DNA caught on film

DNA mutations cause tumor cells to grow out of control, but they also generate variety that enables organisms to adapt to their environments and evolve. Until now, biologists have only had crude methods for estimating the average rates and effects of mutations. But in a new study, biophysicists have documented individual mutations as they happen in bacterial cells.…

Astronaut’s DNA no longer matches that of his identical twin, NASA finds

Spending a year in space not only changes your outlook, it transforms your genes. Preliminary results from NASA's Twins Study reveal that 7% of astronaut Scott Kelly's genes did not return to normal after his return to Earth two years ago. The study looks at what happened to Kelly before, during and after he spent…
