Published Want to cut emissions that cause climate change? Tax carbon
(via sciencedaily.com) Putting a price on producing carbon is the cheapest, most efficient policy change legislators can make to reduce emissions that cause climate change, new research suggests.
Published Researchers discover that privacy-preserving tools leave private data anything but
(via sciencedaily.com) Researchers explored whether private data could still be recovered from images that had been 'sanitized'' by such deep-learning discriminators as privacy protecting GANs (PP-GANs).
Published Heat-free optical switch would enable optical quantum computing chips
(via sciencedaily.com) In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.
Published Gulf Oil Spill's long-lasting legacy for dolphins
(via sciencedaily.com) Health impacts from a 2010 spill are found even in dolphins born years later.
Published COVID-19 lockdown highlights ozone chemistry in China
(via sciencedaily.com) Recently, the ozone season in China has been getting longer, spreading from summer into early spring and late winter. The COVID-19 lockdown can help explain why. Researchers found that decreases in NOx emissions are driving increased ozone pollution in late winter in China.
Published Laser system generates random numbers at ultrafast speeds
(via sciencedaily.com) Scientists have developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in today's digitally connected world.
Published Forests' long-term capacity to store carbon is dropping in regions with extreme annual fires
(via sciencedaily.com) Researchers have analysed decades' worth of data on the impact of repeated fires on ecosystems across the world. Their results show that repeated fires are driving long-term changes to tree communities and reducing their population sizes.
Published Quantum systems learn joint computing
(via sciencedaily.com) Researchers realize quantum-logic computer operation between two separate quantum modules in different laboratories.
Published Traditional hydrologic models may misidentify snow as rain, new citizen science data shows
(via sciencedaily.com) Original source Normally, we think of the freezing point of water as 32°F - but in the world of weather forecasting and hydrologic prediction, that isn't always the case. In the Lake Tahoe region of the Sierra Nevada, the shift from snow to rain during winter storms may actually occur at temperatures closer to 39.5°F, according to new research from the Desert Research Institute (DRI), Lynker Technologies, and citizen scientists from the Tahoe Rain or Snow project.
Published Long-term exposure to low levels of air pollution increases risk of heart and lung disease
(via sciencedaily.com) Analysis of records for more than 63 million Medicare enrollees from 2000 to 2016 finds long-term exposure to air pollution had a significant impact on the number of people hospitalized for cardiac and respiratory conditions. Researchers examined three components of air pollution: fine particulate matter, nitrogen dioxide and ozone. Even levels lower than national standards affected heart and respiratory illnesses.
Published Quantum computing: When ignorance is wanted
(via sciencedaily.com) Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.
Published Oil spill has long-term immunological effects in dolphins
(via sciencedaily.com) A study has found long-term impacts of the 2010 Deepwater Horizon oil spill in the northern Gulf of Mexico on bottlenose dolphins' immune function.
Published Cybersecurity vulnerabilities of common seismological equipment
(via sciencedaily.com) Seismic monitoring devices linked to the internet are vulnerable to cyberattacks that could disrupt data collection and processing, say researchers who have probed the devices for weak points.
Published Emissions of banned ozone-depleting substance are back on the decline
(via sciencedaily.com) Global emissions of a potent substance notorious for depleting the Earth's ozone layer -- the protective barrier which absorbs the Sun's harmful UV rays -- have fallen rapidly and are now back on the decline, according to new research.
Published How iodine-containing molecules contribute to the formation of atmospheric aerosols, affect climate
(via sciencedaily.com) Original source Chemists have helped discover that iodic acids can rapidly form aerosol particles in the atmosphere, giving scientists more knowledge of how iodine emissions can contribute to cloud formation and climate change.
Published Sensor and detoxifier in one
(via sciencedaily.com) Ozone is a problematic air pollutant that causes serious health problems. A newly developed material not only quickly and selectively indicates the presence of ozone, but also simultaneously renders the gas harmless. The porous '2-in-one systems' also function reliably in very humid air.
Published Extreme UV laser shows generation of atmospheric pollutant
(via sciencedaily.com) Scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous acid.
Published Immense hydrocarbon cycle discovered in world's ocean
(via sciencedaily.com) Hydrocarbons and petroleum are almost synonymous in environmental science. After all, oil reserves account for nearly all the hydrocarbons we encounter. But the few hydrocarbons that trace their origin to biological sources may play a larger ecological role than scientists originally suspected.
Published Say goodbye to the dots and dashes to enhance optical storage media
(via sciencedaily.com) A new technology is aimed at modernizing the optical digital storage technology. This advancement allows for more data to be stored and for that data to be read at a quicker rate. Rather than using the traditional dots and dashes as commonly used in these technologies, the innovators encode information in the angular position of tiny antennas, allowing them to store more data per unit area.
Published Failed storage tanks pose atmospheric risks during disasters
(via sciencedaily.com) Engineers model the hypothetical threats from toxins released when above-ground storage tanks fail during a storm. Using data from hurricanes Ike and Harvey and from the Houston Ship Channel, they illustrate potential atmospheric pollutants during and after a disaster.
