Metal-organic frameworks were the next big thing in chemistry when they were invented more than three decades ago. Now, these intriguing materials are becoming commercial tools for capturing carbon dioxide and harvesting water from the air.

A parasitic worm may help rebuild blue crab populations in the Chesapeake Bay
Parasitic, egg-eating worms might sound like the stuff of nightmares, but they’re simply a fact of life for blue crabs in the Chesapeake Bay.
Interestingly, a new study published in the journal PLOS One by researchers at William & Mary’s Batten School & VIMS suggests these worms could serve as a valuable biomarker for managing the fishery.
The most recent Winter Dredge Survey, conducted by the Batten School of Coastal & Marine Sciences & VIMS in collaboration with Maryland’s Department of Natural Resources, recorded historically low numbers of blue crabs in the Chesapeake Bay. The findings have sparked concern among the fishery’s many stakeholders and highlight a need for new tools that can help balance economic and ecological priorities—this study may help with that.
More misfolded proteins than previously known may contribute to Alzheimer’s and dementia
For decades, the story of Alzheimer’s research has been dominated by a battle between A-beta and tau amyloids, both of which can kill neurons and impact the brain’s ability to function. A new study suggests, however, that these sticky brain plaques may not be operating alone.
Johns Hopkins University researchers have identified more than 200 types of misfolded proteins in rats that could be associated with age-related cognitive decline.
The findings could lead the way to finding new therapeutic targets and treatments in humans that could provide relief for the millions of people over 65 who suffer from Alzheimer’s, dementia, or other diseases that rob them of their memories and independence as they age.
Study finds psilocybin extends cellular lifespan and promotes healthy aging
According to researchers from Baylor College of Medicine and Emory University, psilocybin, the active compound in psychedelic mushrooms, may have significant anti-aging properties, extending human cell lifespan by up to 57% in laboratory studies and improving survival rates in aged mice by 30% compared to untreated controls.
Scientists Succeed in Reversing Parkinson’s Symptoms in Mice
In 2017, he led a study that identified for the first time an abnormal form of a protein called SOD1 in Parkinson’s patients. Under normal conditions, this protein acts as an antioxidant enzyme, protecting brain cells from damage caused by free radicals, highly reactive molecules that contain oxygen and can deteriorate cells if not properly neutralized. Free radicals are produced by natural bodily processes as well as by external factors, like diet, smoking, and exposure to pollution.
In people with Parkinson’s disease, SOD1 suffers alterations that prevent it from fulfilling its protective function, with it instead accumulating in the brain and causing neuronal damage, according to the findings of Double’s team.
Based on these results, the team then conducted further research, with results suggesting that copper supplementation in the brain could be an effective way to slow and even reverse the symptoms of Parkinson’s (copper is crucial to SOD1’s function). To test this hypothesis, they evaluated the efficacy of a drug called CuATSM, designed to cross the blood-brain barrier and deliver copper directly to brain tissue.
“Robot Greeters Now Speak 15 Languages”: Realbotix Unleashes Multilingual Androids Into US Hotels, Transforming Guest Service and Shaking the Global Hospitality Market

Astronomers say new interstellar visitor 3I/ATLAS is ‘very likely to be the oldest comet we have ever seen’
The thick disk is a band of our galaxy’s most ancient stars that sandwiches the thin disk, which formed more recently and contains our relatively young star, the sun, and the solar system.
“This is an object from a part of the galaxy we’ve never seen up close before,” University of Oxford astrophysicist Chris Lintott said. “We think there’s a two-thirds chance this comet is older than the solar system, and that it’s been drifting through interstellar space ever since.”
If 3I/ATLAS originates from the Milky Way’s thick stellar disk, and thus formed around an ancient star, this also has implications for its chemical composition. Hopkins and crew suggest the interstellar interloper may be rich in water ice.
CDH2 mutation affecting N-cadherin function causes attention-deficit hyperactivity disorder in humans and mice
Molecular mechanisms of attention-deficit hyperactivity disorder (ADHD) are not fully understood. Here the authors demonstrate a mutation in CDH2, encoding N-cadherin, that is associated with ADHD, and in a mouse model, delineate molecular electrophysiological characteristics associated with this mutation.
