Published Low-cost gel film can pluck drinking water from desert air
(via sciencedaily.com) Researchers developed a low-cost gel film made of abundant materials that can pull drinkable water from the air in even the driest climates.
Published New measurements from Northern Sweden show less methane emissions than feared
(via sciencedaily.com) It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted from a thaw. A crucial, yet an open question is how much precipitation the future will bring.
Published Unlocking the secrets of killer whale diets and their role in climate change
(via sciencedaily.com) Researchers have discovered new clues to understand how killer whales impact their environment.
Published Satellite monitoring of biodiversity moves within reach
(via sciencedaily.com) Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring.
Published Study provides long-term look at ways to control wildfire in sagebrush steppe ecosystem
(via sciencedaily.com) New research provides the first long-term study of methods to control the spread of wildfire in the sagebrush steppe ecosystem that dominates parts of the western United States.
Published New research documents domestic cattle genetics in modern bison herds
(via sciencedaily.com) A new study has revealed the strongest evidence to date that all bison in North America carry multiple small, but clearly identifiable, regions of DNA that originated from domestic cattle.
Published Are new carbon sinks appearing in the Arctic?
(via sciencedaily.com) Original source Global warming can result in the spread of peatland vegetation in the Arctic. An international research group has discovered signs of 'proto-peat', which may be the beginning of new peatlands.
Published Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects
(via sciencedaily.com) Original source Pervasive parasitic infections reduce herbivory rates and can therefore trigger trophic cascades that impact plant communities, according to new research. This work helps fill a recognized knowledge gap regarding the ecological consequences of parasitic infections in natural ecosystems.
Published The forest as a shelter for insects in warmer climates?
(via sciencedaily.com) Insect diversity is declining in Bavaria. Land use is a major driver, but the impact of climate change is still unknown. A study has now investigated in more detail how both factors interact in driving insect diversity and what can be done to conserve it.
Published Self-propelled, endlessly programmable artificial cilia
(via sciencedaily.com) Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.
Published New method can predict summer rainfall in the Southwest months in advance
(via sciencedaily.com) As reservoir levels dwindle in the Southwest, scientists have developed a method to estimate summer rainfall in the region months in advance. These seasonal predictions can enable state and local officials to make key reservoir and water allocation decisions earlier in the season and support more efficient water management.
Published Scientific advance leads to a new tool in the fight against hackers
(via sciencedaily.com) A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.
Published With dwindling water supplies, the timing of rainfall matters
(via sciencedaily.com) A new study shows it's not how much extra water you give your plants, but when you give it that counts. Researchers observed that in summer, plants grow more when given extra water, in addition to any natural rainfall. However, the same is not true in winter.
Published New technique offers faster security for non-volatile memory tech
(via sciencedaily.com) Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.
Published Technology has the potential to change the patient-provider relationship
(via sciencedaily.com) As personal health records (AKA patient portals) allowing patients to see test results, medications and other health information gain in popularity, scientists studied cancer patients' and doctors' differing perceptions of this tool. Patients cited potential for personal health records to deepen their relationship with their healthcare provider and to allow them to be more understood. Physicians were interested in having more clinical information sharing to facilitate better patient care.
Published Deserts 'breathe' water vapor, study shows
(via sciencedaily.com) Deserts may seem lifeless and inert, but they are very much alive. Sand dunes, in particular, grow and move -- and according to a decades long research project, they also 'breathe' humid air.
Published Single-photon source paves the way for practical quantum encryption
(via sciencedaily.com) Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
Published Tiny, cheap solution for quantum-secure encryption
(via sciencedaily.com) Engineers propose a new kind of encryption to protect data in the age of quantum computers.
Published Qubits: Developing long-distance quantum telecommunications networks
(via sciencedaily.com) Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There is one obstacle, however: after a few hundred kilometers within an optical fiber, the photons that carry the qubits or 'quantum bits' (the information) disappear. They therefore need 'repeaters', a kind of 'relay', which are partly based on a quantum memory. By managing to store a qubit in a crystal (a 'memory') for 20 milliseconds, a team has now taken a major step towards the development of long-distance quantum telecommunications networks.
Published Tiny magnets could hold the secret to new quantum computers
(via sciencedaily.com) Scientists have discovered a type of magnetic behavior that could help enable magnetically based quantum devices.
