Published Biomanufacturing using chemically synthesized sugars enables sustainable supply of sugar without competing with food
(via sciencedaily.com) Original source Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.
Published A century of reforestation helped keep the eastern US cool
(via sciencedaily.com) Original source Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
Published Benefits of heat pumps
(via sciencedaily.com) Original source Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition.
Published CRISPR-copies: New tool accelerates and optimizes genome editing
(via sciencedaily.com) Original source Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.
Published Australia's most at-risk bird species share some common traits
(via sciencedaily.com) Original source Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.
Published Frequent marine heatwaves in the Arctic Ocean will be the norm
(via sciencedaily.com) Original source Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new study.
Published Greenland's ice sheet is melting -- and being replaced by vegetation
(via sciencedaily.com) Original source An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.
Published Eco-friendly way to generate power from waste wood
(via sciencedaily.com) Original source A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
Published If we can't untangle this mess, Norway's blue industry will never be green
(via sciencedaily.com) Original source For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.
Published Polar bears unlikely to adapt to longer summers
(via sciencedaily.com) Original source More time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly bear relatives and either rest or eat terrestrial food. The polar bears in this study tried versions of both strategies -- with little success.
Published Global deforestation leads to more mercury pollution
(via sciencedaily.com) Original source Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.
Published Key advance for capturing carbon from the air
(via sciencedaily.com) Original source A chemical element so visually striking that it was named for a goddess shows a 'Goldilocks' level of reactivity -- neither too much nor too little -- that makes it a strong candidate as a carbon scrubbing tool.
Published When the global climate has the hiccups
(via sciencedaily.com) Original source Climate changes usually happens over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers have now been able to prove the phenomenon also occurred during the penultimate glacial period.
Published Immune genes are altered in Alzheimer's patients' blood
(via sciencedaily.com) Original source A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.
Published Sensors made from 'frozen smoke' can detect toxic formaldehyde in homes and offices
(via sciencedaily.com) Original source Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
Published Conversion process turns greenhouse gas into ethylene
(via sciencedaily.com) Original source Engineers have created a more efficient way of converting carbon dioxide into valuable products while simultaneously addressing climate change.
Published Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets
(via sciencedaily.com) Original source Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.
Published Alien invasion: Non-native earthworms threaten ecosystems
(via sciencedaily.com) Original source Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.
Published Industrial pollution leaves its mark in Mediterranean corals
(via sciencedaily.com) Original source For the first time, pollutants from burning fossil fuels have been found embedded in corals, offering scientists a potential new tool to track the history of pollution, finds a new study.
Published Researchers unveil method to detect 'forever chemicals' in under 3 minutes
(via sciencedaily.com) Original source PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
