MOSS LANDING, CA--MBARI researchers recently measured high concentrations of carbon dioxide in air blowing out to sea from cities and agricultural areas, including Silicon Valley. In a new paper in PLOS ONE, they calculate that this previously undocumented process could increase the amount of carbon dioxide dissolving into coastal ocean waters by about 20 percent.
A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of researchers from Penn State developed the sensor from a protein they recently described and subsequently used it to explore the biology of bacteria that use lanthanides. A study describing the sensor appears online in the Journal of the American Chemical Society.
For people who survive a heart attack, the days immediately following the event are critical for their longevity and long-term healing of the heart's tissue. Now researchers at Northwestern University and University of California, San Diego (UC San Diego) have designed a minimally invasive platform to deliver a nanomaterial that turns the body's inflammatory response into a signal to heal rather than a means of scarring following a heart attack.
Human skeletal muscles have a unique combination of properties that materials researchers seek for their own creations. They're strong, soft, full of water, and resistant to fatigue. A new study by MIT researchers has found one way to give synthetic hydrogels this total package of characteristics: putting them through a vigorous workout.
Despite volumes of data currently available on mankind, it is surprising how little we know about other species. A paper published this week in the journal Proceedings of the National Academy of Sciences (PNAS) confirms that critical information, such as fertility and survival rates, is missing from global data for more than 98 percent of known species of mammals, birds, reptiles, and amphibians.
Scientists from TPU, Germany, and the United States have found a new way to functionalize a dielectric, otherwise known as 'white graphene', i.e. hexagonal boron nitride (hBN), without destroying it or changing its properties. Thanks to the new method, the researchers synthesized a 'polymer nano carpet' with strong covalent bond on the samples.
Prof Raul Rodriguez from the TPU Research School of Chemistry & Applied Biomedical Sciences explains:
Fire ecologists and wildlife specialists at La Trobe University have made key discoveries in how wildlife restores itself after bushfires, and what Australian conservationists can do to assist the process.
The study, published this week in Wildlife Research journal, looks at various reserves in the Australian state of Victoria after bushfires had taken place. It finds that the surrounding area of any fire dictates what species survived and went onto thrive.
Key findings of the study included:
A pair of researchers at Tokyo Institute of Technology (Tokyo Tech) describes a way of making a submicron-sized cylinder disappear without using any specialized coating. Their findings could enable invisibility of natural materials at optical frequency  and eventually lead to a simpler way of enhancing optoelectronic devices, including sensing and communication technologies.
OAKLAND, Calif. - More than 80 percent of all waste from Pennsylvania's oil and gas drilling operations stays inside the state, according to a new study that tracks the disposal locations of liquid and solid waste from these operations across 26 years. Numerous human health hazards have been associated with waste from oil and gas extraction, including potential exposure to compounds known to cause cancer.
The iconic "death roll" of alligators and crocodiles may be more common among species than previously believed, according to a new study published in Ethology, Ecology & Evolution and coauthored by a researcher at the University of Tennessee, Knoxville.
