Did Bats Invent Fireflies?

Boise State University

Bats can learn to avoid fireflies using sonar or vision, but they learn faster they use both. This is evidence that combining information across senses can increase the power of warning signals. This research has implications for how fireflies evolved in relation to bats.

Theory, meet Empiry

Santa Fe Institute

It may seem that there isn't much cross-discussion between theoretical and empirical scientists, but a new cross-citation network analysis shows there is more overlap than many believe.

Genomes of Ape Parasites Reveal Origin and Evolution of Leading Cause of Malaria Outside of Africa

Perelman School of Medicine at the University of Pennsylvania

The genome sequences of ape parasites related to Plasmodium vivax, the main source of mosquito-borne malaria outside Africa, provide insights on the origin and early evolution of the human parasite. This finding could have implications for better comprehending and eradicating malaria infection worldwide.

Research Indicates Long-Legged Lizards Better Adapted for Hurricane Survival

University of Rhode Island

Jason Kolbe has been thinking about hurricanes and lizards for many years. The University of Rhode Island professor of biological sciences has measured the length of lizard legs and the size of their toe pads to assess how those factors influence the animal’s ability to cling to vegetation during strong storms. He even used a powerful leaf blower to test his hypotheses in a laboratory.

Study of Ancient Forefoot Joints Reveals Bipedalism in Hominins Emerged Early

Stony Brook University

In the first comprehensive study of the forefoot joints of ancient hominins, to be published online in PNAS, an international team of researchers conclude that adaptations for bipedal walking in primates occurred as early as 4.4 million years ago

A Scientific Dating Game: Biologists Play RNA-Protein Matchmakers

University of Texas at Dallas

Virtually all functions in our bodies require precise interactions between radically different types of molecules. Researchers at The University of Texas at Dallas are pursuing what differentiates a fruitful encounter from a dud.

Chemistry Research ‘Rocks’ New Data about Ancient Life

University of California San Diego

Sulfur isotopes can serve as tracers of atmospheric oxygen, and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period’s sulfur isotope sedimentary signature—a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.

Leggy Lizards Don’t Survive the Storm

Washington University in St. Louis

Nobody knows exactly what happens at the eye of the storm. But biologists have published a first-of-its-kind look at the physical characteristics of lizards that seem to make the difference between life and death in a hurricane, as reported on July 25 in the journal Nature. Hint: long, strong back legs do not help like you think they might.

Unisexual salamander evolution: A long, strange trip

Ohio State University

The reproductive history of the unisexual, ladies-only salamander species is full of evolutionary surprises. In a new study, a team of researchers at The Ohio State University traced the animals’ genetic history back 3.4 million years and found some head-scratching details – primarily that they seem to have gone for millions of years without any DNA contributions from male salamanders and still have managed to persist.
