Reconciling predictions of climate change
Harvard researchers have resolved a major conflict in estimates of how much the Earth will warm in response to a doubling of CO2 in the atmosphere -- finding that the lower range of estimates offered by historical observations does not take into account long-term patterns of warming. The research finds a range of 1.5 to 4.5 degrees Celsius, even up to 6 degrees, may also be possible due to a doubling of CO2.

International team develops new way to produce pure hydrogen efficiently
An international team of researchers, including Lehigh University's Christopher J. Kiely, have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). Their discovery is described in a paper published recently in Science.

Recreating interstellar ions with lasers
Trihydrogen, or H3+, has been called the molecule that made the universe, where it plays a greater role in astrochemistry than any other molecule. While H3+ is astronomically abundant, no scientist understood the mechanisms that form it from organic molecules.

Dinosaurs' loss was frogs' gain: The upside of a mass extinction
Based on earlier studies, biologists believed that the vast majority of today's frogs originated in a blossoming of new species 100 million years ago. New and more complete genetic data pinpoints this radiation much earlier: 66 million years ago at the Cretaceous-Paleogene boundary, precisely when much of life on Earth was wiped out by a comet or asteroid. Frogs took advantage of flourishing angiosperms to escape to the treetops into many more ecological niches.

Utah is home to earliest use of a wild potato in North America
Researchers have discovered potato starch residues in the crevices of a 10,900-year-old stone tool in Escalante, Utah -- the earliest evidence of wild potato use in North America. This is the first archaeological study to identify Solanum jamesii, a wild species native to the southwestern United States, as an important part of ancient human diets. The long history could mean that the species was transported, cultivated or even domesticated.

Frogs illustrate the creative destruction of mass extinctions
Using the largest set of frog genetic data ever evaluated for evolutionary relationships, researchers discover not one but three explosions of new frog species, all concentrated in the aftermath of the mass die-off of most dinosaurs and many other species about 66 million years ago.

In urban Baltimore, poor neighborhoods have more mosquitoes
A new study published in the Journal of Medical Entomology reports that in Baltimore, Maryland, neighborhoods with high levels of residential abandonment are hotspots for tiger mosquitoes (Aedes albopictus). This environmental injustice may leave low-income urban residents more vulnerable to mosquito-borne disease.

Bizarro comet challenging researchers  
Scientists pursue research through observation, experimentation and modeling. They strive for all of these pieces to fit together, but sometimes finding the unexpected is even more exciting.  That's what happened to University of Central Florida's astrophysicist Gal Sarid, who studies comets, asteroids and planetary formation and earlier this year was part of a team that published a study focused on the comet 174P/Echeclus. It didn't behave the way the team was expecting.
