The presence of the carp, a freshwater invasive species spread worldwide, is alarmingly reducing the populations of diving ducks and waterbirds, according to a study published in the journal Biological Conservation by the researchers Alberto Maceda Veiga, from the Biodiversity Research Institute of the University of Barcelona (IRBio) and Raquel López and Andy J. Green, from the Doñana Biological Station (EBD-CSIC).

This is the first study which clearly shows the ecological impact of the carp on water birds in Mediterranean shallow lakes, and it warns about the dramatic effect of this invasive species on other species such as the white-headed duck (Oxyura leucocephala) and the red-crested pochard (Aythya farina), classified as endangered species by the International Union for Conservation of Nature (UICN).

In their work toward 3-D printing transplantable tissues and organs, bioengineers and scientists from Rice University and Baylor College of Medicine have demonstrated a key step on the path to generate implantable tissues with functioning capillaries.

The future cost of energy storage technologies can now be predicted under different scenarios, thanks to a new tool created by Imperial researchers.

Using a large database, the team can predict how much consumers will have to pay in the future for energy storage technologies based on cumulative installed capacity, current cost and future investment.

Harvard University researchers have resolved a conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere.  That conflict — between temperature ranges based on global climate models and paleoclimate records and ranges generated from historical observations — prevented the United Nations’ Intergovernmental Panel on Climate Change (IPCC) from providing a best estimate in its most recent report for how much the Earth will warm as a result of a doubling of CO2 emissions.

Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design in the journal Nature Energy.

The team, led by Yury Gogotsi, PhD,Distinguished University and Bach professor in Drexel’s College of Engineering, in the Department of Materials Science and Engineering, created the new electrode designs from a highly conductive, two-dimensional material called MXene. Their design could make energy storage devices like batteries, viewed as the plodding tanker truck of energy storage technology, just as fast as the speedy supercapacitors that are used to provide energy in a pinch — often as a battery back-up or to provide quick bursts of energy for things like camera flashes.
