Citizen-science climate project adds logs from historic Arctic whaling ships

Old Weather is a citizen-science project that is mining historic ship logs to get a unique peek at the history of Arctic climate. Now volunteers will transcribe logbooks from hundreds of whaling ships that recorded Arctic conditions in the late 1800s a...

Microtubules act as cellular ‘rheostat’ to control insulin secretion

Microtubules -- cellular 'highways' that deliver cargo to the cell membrane for secretion -- have a surprising role in pancreatic beta cells. Instead of facilitating glucose-stimulated insulin secretion, they limit it, a team of investigators report. T...

How cells are foiled by a herpesvirus family member in the virus-host arms race

Not every virus wants to go viral right away -- some want to wait for the perfect opportunity to attack. So the virus has to find a way to enter the cells of the human body without tripping the alarm. It's how viruses in the herpesvirus family, like hu...

New way to make yeast hybrids may inspire new brews, biofuels

Thanks to a new method for making interspecies yeast hybrids in the lab, the makers of beer, wine, biofuels and other products that depend on yeasts may soon have many more strains of the microorganism to work with.

Microtubules act as cellular ‘rheostat’ to control insulin secretion

Microtubules—cellular "highways" that deliver cargo to the cell membrane for secretion—have a surprising role in pancreatic beta cells. Instead of facilitating glucose-stimulated insulin secretion, they limit it, a team of Vanderbilt investigators reported recently in Developmental Cell.

A Camera That Sees Methane

Swedish scientists have built a camera that makes methane gas visible. The tool could help researchers study greenhouses gases and answer tricky questions about climate change. It's also good for visualizing cow farts. Magnus Gålfalk of Linköping University explains that the camera works using infrared spectroscopy. Called "hyperspectral imaging," the method simultaneously captures a spectrum of infrared light for every pixel in a photo. Many gases absorb infrared light, Gålfalk says, not
