Published Research provides crucial insights into moss growth under elevated CO2 levels that may benefit climate change models
(via sciencedaily.com)
Original source 
Approximately 12,000 species of mosses exist and cover close to four million square miles of earth, equivalent to the size of Canada, and are ecologically and evolutionarily important. Mosses play an essential role in rainwater retention, decreasing plant pathogens and increasing carbon sequestration in soil, thus improving the overall soil health. Mosses also protect long-term carbon storage systems, such as bogs and permafrost.
Published New twist on AI makes the most of sparse sensor data
(via sciencedaily.com)
Original source 
An innovative approach to artificial intelligence (AI) enables reconstructing a broad field of data, such as overall ocean temperature, from a small number of field-deployable sensors using low-powered 'edge' computing, with broad applications across industry, science and medicine.
Published New tool models viability of closed-loop geothermal systems
(via sciencedaily.com)
Original source 
Researchers have used computer models of closed-loop geothermal systems to determine if they would be economically viable sources of renewable energy. They found that the cost of drilling would need to decrease significantly to hit cost targets.
Published When we see what others do, our brain sees not what we see, but what we expect
(via sciencedaily.com)
Original source 
When we engage in social interactions, like shaking hands or having a conversation, our observation of other people's actions is crucial. But what exactly happens in our brain during this process: how do the different brain regions talk to each other? Researchers provide an intriguing answer: our perception of what others do depends more on what we expect to happen than previously believed.
Published Another step toward the HIV-1 vaccine: Dynamics of neutralizing antibodies
(via sciencedaily.com)
Original source 
Longevity of neutralizing antibodies is an essential factor for an effective HIV-1 vaccination.
Published Keep it secret: Cloud data storage security approach taps quantum physics
(via sciencedaily.com)
Original source 
Distributed cloud storage is a hot topic for security researchers, and a team is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage solution.
Published Putting sound waves to work to create safer public spaces
(via sciencedaily.com)
Original source 
Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors built a system of piezoelectric sensors that can be installed in walls, floors, and ceilings to absorb sound waves and collect their energy. They used computer simulations to fine-tune variables including the voltage needed to power the main device component, the frequency and intensity of the input sound, and piezoelectric sensors tested in parallel and serial configurations.
Published Galactic 'lightsabers': Answering longstanding questions about jets from black holes
(via sciencedaily.com)
Original source 
The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.
Published How tiny hinges bend the infection-spreading spikes of a coronavirus
(via sciencedaily.com)
Original source 
Far from being stiff and pointy, a coronavirus's infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A new study suggests that disabling those hinges could block infection.
Published New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America
(via sciencedaily.com)
Original source 
New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.
Published A tale of two proteins: Fundamental research could make growing better crops like clockwork
(via sciencedaily.com)
Original source 
Rhomboid-like protein 10, or RBL10, is thought to be an enzyme that degrades other proteins in the chloroplast membrane, but its function is largely unknown. Researchers are studying how RBL10 affects photosynthetic membrane lipid metabolism, an essential process in photosynthesis.
Published Hormonal contraceptives in teens may alter risk assessment, rat study suggests
(via sciencedaily.com)
Original source 
Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests.
Published Earth's surface water dives deep, transforming core's outer layer
(via sciencedaily.com)
Original source 
A new study has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a distinct, thin layer. Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction.
Published Faster Arctic warming hastens 2C rise by eight years
(via sciencedaily.com)
Original source 
The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.
Published Scientists uncover aurora-like radio emission above a sunspot
(via sciencedaily.com)
Original source 
Astronomers have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km above a relatively dark and cold patch on the Sun, known as a sunspot.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com)
Original source 
Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Ammonia for fertilizers without the giant carbon footprint
(via sciencedaily.com)
Original source 
Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertilizer vital for crop-growing.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s
(via sciencedaily.com)
Original source 
In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published This wireless, handheld, non-invasive device detects Alzheimer's and Parkinson's biomarkers
(via sciencedaily.com)
Original source 
An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone. The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art method. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well. The device relies on electrical rather than chemical detection, which researchers say is easier to implement and more accurate.
