Published Environmental impact reports hugely underestimate consequences for wildlife
(via sciencedaily.com) Original source Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.
Published Case for Candida auris wastewater surveillance
(via sciencedaily.com) Original source Researchers say tracking methodology in Southern Nevada fungal outbreak provides blueprint for monitoring and responding to emerging global public health threat.
Published Researchers clear the way for well-rounded view of cellular defects
(via sciencedaily.com) Original source New research investigates how cells divide, particularly in the fibrous environment of living tissue. Cells are typically studied in a flat environment, and the difference between flat and fibrous landscapes opens new windows into the behavior of cells and the diseases that impact them.
Published New atomic-scale understanding of catalysis could unlock massive energy savings
(via sciencedaily.com) Original source In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.
Published Fully recyclable printed electronics ditch toxic chemicals for water
(via sciencedaily.com) Original source Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Broccoli consumption protects gut lining, reduces disease, in mice
(via sciencedaily.com) Original source Broccoli is known to be beneficial to our health. For example, research has shown that increased consumption of the cruciferous vegetable decreases incidence of cancer and type 2 diabetes. In a recent study, researchers found that broccoli contains certain molecules that bind to a receptor within mice and help to protect the lining of the small intestine, thereby inhibiting the development of disease. The findings lend support to the idea that broccoli truly is a 'superfood.'
Published Blind dating in bacteria evolution
(via sciencedaily.com) Original source A team of researchers reconstructed long-extinct proteins of a UV protection system of cyanobacteria. The surprising result: the proteins were already compatible with each other when they first met. This discovery expands the knowledge horizon on the rules of evolution.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Sierra squirrels find their niche amid a changing climate
(via sciencedaily.com) Original source A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published AI-equipped eyeglasses read silent speech
(via sciencedaily.com) Original source Researchers have developed a silent-speech recognition interface that uses acoustic-sensing and artificial intelligence to continuously recognize up to 31 unvocalized commands, based on lip and mouth movements.
Published NASA's Webb scores another ringed world with new image of Uranus
(via sciencedaily.com) Original source Following in the footsteps of the Neptune image released in 2022, NASA's James Webb Space Telescope has taken a stunning image of the solar system's other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet's atmosphere. The Webb data demonstrates the observatory's unprecedented sensitivity for the faintest dusty rings, which have only ever been imaged by two other facilities: the Voyager 2 spacecraft as it flew past the planet in 1986, and the Keck Observatory with advanced adaptive optics.
Published Two-dimensional nanoparticles with great potential
(via sciencedaily.com) Original source A research team has discovered how catalysts and many other nanoplatelets can be produced in an environmentally friendly way from readily available materials and in sufficient quantities.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more
(via sciencedaily.com) Original source Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published Hubble sees possible runaway black hole creating a trail of stars
(via sciencedaily.com) Original source There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.
Published Researchers create embryo-like structures from monkey embryonic stem cells
(via sciencedaily.com) Original source Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. Investigators now report on the creation of embryo-like structures from monkey embryonic stem cells. The investigators also transferred these embryo-like structures into the uteruses of female monkeys and determined that the structures were able to implant and elicit a hormonal response similar to pregnancy.
Published Activating adult-born neurons through deep brain stimulation alleviates Alzheimer's symptoms in rodent models
(via sciencedaily.com) Original source People with Alzheimer's disease develop defects in cognitive functions like memory as well as problems with noncognitive functions that can lead to anxiety and depression. Investigators used mice to study a process through which new neurons are generated in adulthood, called adult hippocampus neurogenesis (AHN). The research showed that deep brain stimulation of new neurons helped restore both cognitive and noncognitive functions in mouse models of Alzheimer's disease.
Published US forests face an unclear future with climate change
(via sciencedaily.com) Original source Climate change might compromise how permanently forests are able to store carbon and keep it out of the air. In a new study, researchers found that the regions most at risk to lose forest carbon through fire, climate stress or insect damage are those regions where many forest carbon offset projects have been set up. The authors assert that there's an urgent need to update these carbon offsets protocols and policies.
Published Super-sized nanocage could deliver bigger drug cargoes
(via sciencedaily.com) Original source Nanocages are tiny artificial containers that can be used to deliver therapeutics to a target destination in the body. But some drug molecules are like gifts that are too big for a standard-sized nanocage 'box'. Now researchers describe how they have built a super-sized nanocage that could be used to deliver larger drug cargoes. They have built a bigger box.
Published Shedding light on mechanisms of electrochemical energy storage
(via sciencedaily.com) Original source Researchers have developed a new technique that can quickly identify the exact electrochemical mechanisms taking place in batteries and supercapacitors of various compositions -- a breakthrough that could speed the design of higher performing energy storage devices.
Published Twinkling stars fuel interstellar dust
(via sciencedaily.com) Original source Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust. Dusty AGBs are particularly prominent producers of dust, and the light they shine happens to vary widely. For the first time, a long-period survey has found the variable intensity of dusty AGBs coincides with variations in the amount of dust these stars produce. As this dust can lead to the creation of planets, its study can shed light on our own origins.
