Published How much spring nitrogen to apply? Pre-planting weather may provide a clue
(via sciencedaily.com) With the rising cost of nitrogen fertilizer and its impacts on air and water quality, researchers want to help farmers make more informed fertilizer rate decisions. Their latest modeling effort aims to do that by examining the role of pre-growing season weather on soil nitrogen dynamics and end-of-season corn yield.
Published Radio waves for the detection of hardware tampering
(via sciencedaily.com) Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.
Published Less air pollution leads to higher crop yields
(via sciencedaily.com) New analysis shows crop yields could increase by about 25% in China and up to 10% in other parts of the world if emissions of a common air pollutant decreased by about half.
Published Research shows how Gulf of Mexico escaped ancient mass extinction
(via sciencedaily.com) An ancient bout of global warming 56 million years ago that acidified oceans and wiped-out marine life had a milder effect in the Gulf of Mexico, where life was sheltered by the basin's unique geology. The findings could help scientists determine how current climate change will affect marine life and aid in efforts to find deposits of oil and gas.
Published Oil spill remediation: Research confirms effectiveness of oil dispersants
(via sciencedaily.com) Chemical dispersants are some of the best tools to clean up after an oil spill. However, scientists do not fully understand how well they work. A new study validated their efficacy in order to better prepare for the next disaster.
Published Secure communication with light particles
(via sciencedaily.com) While quantum computers offer many novel possibilities, they also pose a threat to internet security since these supercomputers make common encryption methods vulnerable. Based on the so-called quantum key distribution, researchers have developed a new, tap-proof communication network.
Published Researchers develop new biobattery for hydrogen storage
(via sciencedaily.com) A team of microbiologists has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest of climate protection.
Published Emulating impossible 'unipolar' laser pulses paves the way for processing quantum information
(via sciencedaily.com) A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing.
Published How ice clouds develop: Asian monsoon influences large parts of the Northern Hemisphere
(via sciencedaily.com) Atmospheric researchers have discovered a mechanism that allows nuclei for ice clouds to form and rapidly grow in the upper troposphere. Although the conditions for nucleus formation are only fulfilled in the Asian monsoon region, the mechanism is expected to have an impact on ice cloud formation across large parts of the Northern Hemisphere.
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 In poplars, two plant hormones boost each other in defense against pathogenic fungi
(via sciencedaily.com) In contrast to previous assumptions, the defense hormones salicylic acid and jasmonic acid do not always suppress each other in regulating plant chemical defenses against pests and pathogens. In trees, the interplay of both hormones can actually increase plant resistance.
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 Lesser known ozone layer's outsized role in planet warming
(via sciencedaily.com) New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean -- one of Earth's main cooling systems.
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 Exposure assessment for Deepwater Horizon oil spill: Health outcomes
(via sciencedaily.com) Mathematicians have developed statistical methods that lay the framework for the crucial first step of determining whether there are any linkages between exposures and health outcomes from the 2010 Deepwater Horizon oil spill, which is considered the largest marine oil spill in the history of the U.S.
Published A 4 V-class metal-free organic lithium-ion battery gets closer to reality
(via sciencedaily.com) Organic, metal free, high-energy batteries are a pathway to a greener future. Yet scientists have struggled to find ways to boost the voltage in organic lithium-ion batteries. Now, a study has proposed a small organic molecule known as croconic acid that can maintain a working voltage of around 4 Volts.
Published How plants activate their immune system against pathogens in rain
(via sciencedaily.com) A recent study has revealed that when plants are exposed to rain, hair-like structures on the leaf surface called trichomes recognize this rain as a risk factor for causing disease and activate their immune system to prevent infections. These findings could contribute to the development of methods to protect plants from infectious diseases caused by rain.
Published Earthworms like to eat some plastics, but side effects of their digestion are unclear
(via sciencedaily.com) Earthworms are a welcome sight for gardeners and farmers because the wriggling invertebrates recycle nutrients from soil, making them more accessible to plants. As worms burrow, they consume almost everything in their path, including microscopic plastic pollution. Now, researchers have observed that earthworms actually prefer soil with some types of microplastics but digest the polymers differently, which the team suggests could impact the animals' health and the ecosystem.
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.
