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.
New research from the University of East Anglia reveals how soil bacteria build the only known enzyme for the destruction of the potent global warming and ozone-depleting gas nitrous oxide.
Alongside carbon dioxide (CO2) and methane, the greenhouse gas nitrous oxide (N2O), commonly known as 'laughing gas', is now a cause for great concern, and there is much international focus on reducing emissions.
Researchers from Drexel University and Trinity College in Ireland, have created ink for an inkjet printer from a highly conductive type of two-dimensional material called MXene. Recent findings, published in Nature Communications, suggest that the ink can be used to print flexible energy storage components, such as supercapacitors, in any size or shape.
Of all the different possible methods to combat anthropogenic climate change conceived of so far, among the least studied is climate engineering.
An umbrella term for large-scale projects designed to disrupt the Earth's carbon cycle or radiation balance, climate engineering has only relatively recently been included in the conversation about methods that could mitigate the harm caused by carbon emissions.
Scientists from the University of East Anglia have discovered a unique oil eating bacteria in the deepest part of the Earth's oceans - the Mariana Trench.
Together with researchers from the China and Russia, they undertook the most comprehensive analysis of microbial populations in the trench.
The Mariana Trench is located in the Western Pacific Ocean and reaches a depth of approximately 11,000 metres. By comparison, Mount Everest is 8,848 metres high.
Well-adorned or well-endowed - but not both. Evolutionary biologists at the University of Zurich have for the first time demonstrated that male primates either have large testicles or showy ornaments. Developing both at the same time may simply take too much energy.
New Haven, Conn. - Cthulhu is calling from the ancient depths -- and this time, researchers are only too happy to speak its name.
Researchers at Yale, Oxford, the University of Leicester, Imperial College London, and University College London have identified a 430 million-year-old fossil as a new species related to living sea cucumbers. They named the creature Sollasina cthulhu, after H.P. Lovecraft's tentacled monster, Cthulhu.
A study announcing the discovery appears April 10 in the journal Proceedings of the Royal Society B.
