Published Catalyst purifies herbicide-tainted water and produces hydrogen
(via sciencedaily.com) Researchers have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.
Published Case study of rare, endangered tortoise highlights conservation priorities for present, future World Wildlife Days
(via sciencedaily.com) Though wildlife trafficking has been effectively disrupted since the first World Wildlife Day -- established 50 years ago today via the 1973 Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora -- a newly published case study on one of the world's rarest tortoise species, the ploughshare tortoise, highlights how much room for improvement still exists.
Published DNA repair discovery could improve biotechnology
(via sciencedaily.com) A team of researchers has made a discovery that may have implications for therapeutic gene editing strategies, cancer diagnostics and therapies and other advancements in biotechnology.
Published Earlier take-off could lead to fewer bumblebees and less pollination
(via sciencedaily.com) With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
Published Bald eagles aren't fledging as many chicks due to avian influenza
(via sciencedaily.com) Bald eagles are often touted as a massive conservation success story due to their rebound from near extinction in the 1960s. But now a highly infectious virus may put that hard-fought comeback in jeopardy. New research showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers of mating pairs of bald eagles.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published Quantum chemistry: Molecules caught tunneling
(via sciencedaily.com) Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
Published Seabirds in the eye of the storm
(via sciencedaily.com) Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.
Published Degrading modified proteins could treat Alzheimer's, other 'undruggable' diseases
(via sciencedaily.com) Certain diseases, including Alzheimer's, are currently considered 'undruggable' because traditional small molecule drugs can't interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and breaks apart certain proteins -- rather than just interfering with them -- may offer a pathway toward treatment. Researchers have now designed a compound that targets and breaks down a post-translationally modified protein closely associated with Alzheimer's disease.
Published Centuries of whaling data highlight likely climate change effect
(via sciencedaily.com) Centuries-old whaling records show how southern right whales are altering their feeding habits.
Published New purification method could make protein drugs cheaper
(via sciencedaily.com) Original source Engineers devised a way to purify protein drugs during manufacturing. Their approach, which uses nanoparticles to rapidly crystallize proteins, could help make protein drugs more affordable and accessible, especially in developing countries.
Published Better metric for prioritizing conservation of 'evolutionarily distinctive' species
(via sciencedaily.com) Researchers have published an updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness.
Published Jurassic shark: Shark from the Jurassic period was already highly evolved
(via sciencedaily.com) Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published Rare insect found in Arkansas sets historic record, prompts mystery
(via sciencedaily.com) A giant insect found in Arkansas has set historic records. The Polystoechotes punctata or giant lacewing is the first of its kind recorded in eastern North America in over 50 years. The giant lacewing was formerly widespread across North America, but was mysteriously extirpated from eastern North America by the 1950s. This discovery suggests there may be relic populations of this large insect yet to be discovered.
Published Sea urchin die-offs threaten Caribbean coral reefs
(via sciencedaily.com) The sustained loss of a once abundant species of sea urchin in the Caribbean could also result in the functional extinction of diverse coral species from the region's reefs, according to new research.
Published New hydrogel stem cell treatment repairs injured brain tissue in mice
(via sciencedaily.com) A new hybrid hydrogel that safely delivers stem cells to brain injury sites in mice has been developed. This solves a major challenge -- keeping stem cells alive for long enough to evolve into the cells required to create new tissue after insertion into a damaged part of the body.
Published New superacid converts harmful compounds into sustainable chemicals
(via sciencedaily.com) Researchers have succeeded in producing very special catalysts, known as 'Lewis superacids', which can be used to break strong chemical bonds and speed up reactions. The production of these substances has, until now, proven extremely difficult. The chemists' discovery enables non-biodegradable fluorinated hydrocarbons, similar to Teflon, and possibly even climate-damaging greenhouse gases, such as sulphur hexafluoride, to be converted back into sustainable chemicals.
Published Dinosaur claws used for digging and display
(via sciencedaily.com) Dinosaur claws had many functions, but now a team has shown some predatory dinosaurs used their claws for digging or even for display.
Published Certain frogs more sensitive to climate change, not protected
(via sciencedaily.com) Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.
