Global warming has forced U.S. plants and animals to change their behavior in recent decades in ways that can be harmful, according to a new report prepared for the Pew Center on Global Climate Change.
The Pew Center review of more than 40 studies is co-authored by Camille Parmesan, integrative biologist at The University of Texas at Austin, and Hector Galbraith of Galbraith Environmental Services, who is affiliated with the University of Colorado at Boulder. Their analyses revealed that more than half the studies provided strong evidence of a direct link between global warming and changes in the behavior of species in the continental United States and Alaska.
"Other recent syntheses of biological impacts, including my own, have focused on very large datasets across the globe," said Parmesan. "The conclusion from those studies is that global climate change has affected about half of all wild species. That’s important, but what people really want to know is what’s happening in their backyard. This is the first study to focus on U.S. datasets. The message from the report is that human-driven climate change has affected species all across the U.S., from new tropical species arriving in Florida to changes in the basic functioning of ecosystems in Alaska."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
