Published Exciting advance in stem cell therapy
(via sciencedaily.com) Original source A new technique for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential.
Published Scientists achieve more than 98% efficiency removing nanoplastics from water
(via sciencedaily.com) Original source Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Changing food consumers' choices may help cut greenhouse gases
(via sciencedaily.com) Original source Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.
Published Surprising insight into cancer comes from unique plant species that find different solutions to evolutionary challenges
(via sciencedaily.com) Original source A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer.
Published Expansion of agricultural land threatens climate and biodiversity
(via sciencedaily.com) Original source Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. How can additional cultivation areas be reconciled with nature conservation? Researchers have developed a land-use model that provides answers.
Published Protecting surf breaks mitigates climate change, helps coastal communities
(via sciencedaily.com) Original source Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, research has shown.
Published Rewriting the evolutionary history of critical components of the nervous system
(via sciencedaily.com) Original source A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published Reduce, reuse, 're-fly-cle'
(via sciencedaily.com) Original source Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.
Published Starvation and adhesion drive formation of keratinocyte patterns in skin
(via sciencedaily.com) Original source Cell-cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion researchers find.
Published Ships now spew less sulfur, but warming has sped up
(via sciencedaily.com) Original source New findings document fewer ship tracks, reduced cloud cover, and boosted warming after ship emissions regulations took effect in 2020.
Published New study unveils 16,000 years of climate history in the tropical Andes
(via sciencedaily.com) Original source Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Study reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease
(via sciencedaily.com) Original source Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease. Oleoyl-ACP-hydrolase (OLAH) is an enzyme involved in fatty acid metabolism. A study shows that OLAH drives severe disease outcomes.
Published Researchers ID body's 'quality control' regulator for protein folding
(via sciencedaily.com) Original source Anyone who's tried to neatly gather a fitted sheet can tell you: folding is hard. Get it wrong with your laundry and the result can be a crumpled, wrinkled mess of fabric, but when folding fails among the approximately 7,000 proteins with an origami-like complexity that regulate essential cellular functions, the result can lead to one of a multitude of serious diseases ranging from emphysema and cystic fibrosis to Alzheimer's disease. Fortunately, our bodies have a quality-control system that identifies misfolded proteins and marks them either for additional folding work or destruction, but how, exactly, this quality-control process functions is not entirely known. Researchers have now made a major leap forward in our understanding of how this quality-control system works by discovering the 'hot spot' where all the action takes place.
Published Forest restoration can boost people, nature and climate simultaneously
(via sciencedaily.com) Original source Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Mature forests vital in frontline fight against climate change
(via sciencedaily.com) Original source Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published Balancing technology and governance are key to achieving climate goals
(via sciencedaily.com) Original source Despite advancements in clean energy, global CO2 emissions continue to rise. IIASA researchers contributed to a new international study that underscores the importance of integrating technological advancements with robust institutional capacities to formulate effective climate policies.
Published How mortal filaments' self-assemble and maintain order: Align or die
(via sciencedaily.com) Original source A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.
Published Drug protects against air pollution-related Alzheimer's signs in mice
(via sciencedaily.com) Original source A new study shows how feeding mice a drug called GSM-15606 provided protection against air pollution-related increases in proteins linked to Alzheimer's disease.
Published Taking a 'one in a million' shot to tackle dopamine-linked brain disorders
(via sciencedaily.com) Original source With the help of a tiny, transparent worm called Caenorhabditis elegans, researchers have identified novel players in dopamine signaling by taking advantage of a powerful platform generated via the Million Mutation Project (MMP) for the rapid identification of mutant genes based on their functional impact. They can seek insights from simpler organisms whose genes bear striking similarity to those found in humans and where opportunities for genetic insights to disease can be pursued more efficiently and inexpensively.
