Drought alters recovery of Rocky Mountain forests after fire

A changing climate is altering the ability of Rocky Mountain forests to recover from wildfire, according to a new study. When warm, dry conditions lead to drought in the years following fires, it impedes the growth and establishment of vulnerable new post-fire seedlings. The study also shows that forest recovery has been negatively affected by increased distances between burned areas and the sources of seeds that typically replace trees lost to fire.

Details revealed for how plant creates anticancer compounds

Rosy periwinkle is a plant that produces organic compounds used to treat cancer, arrhythmia, and other medical conditions. A Japanese research group has revealed the details of the metabolism process for these compounds on a cellular level. Their data suggests the existence of an unknown mechanism which regulates the creation, movement and distribution of compounds within plants.

Wrinkles and crumples make graphene better

Researchers have developed a method for making super-wrinkled and super-crumpled sheets of the nanomaterial graphene. The research shows that the topography can enhance some of graphene's already interesting properties.

Risk of multiple tipping points should be triggering urgent action on climate change

Pioneering new research shows that existing studies have massively under-valued the risk that ongoing carbon dioxide emissions pose of triggering damaging tipping points.

Global warming pushes wines into uncharted terroir

In much of France and Switzerland, the best wine years are traditionally those with an exceptionally hot summer and late-season drought. Now, a study out this week shows that warming climate has largely removed the drought factor from the centuries-old early-harvest equation. It is only the latest symptom that global warming is affecting biological systems and agriculture.

Old tourist photos show seabird's rise over the last century

Researchers have used tourist photos to reconstruct the rise and fall of common guillemots, one of the largest auk species. Those data show that the guillemots suffered early in the 20th century, but their numbers have now risen to a historically high level. They also demonstrate the power of amateur photos and other unconventional sources of evidence to help fill gaps in the scientific record.
