Evolution might stop humans from solving climate change

Science Daily - 03/01/2024
Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.

Understanding climate mobilities: New study examines perspectives from South Florida practitioners

Science Daily - 03/01/2024
A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.

From NYC to DC and beyond, cities on the East Coast are sinking

Science Daily - 03/01/2024
Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.

Elusive cytonemes guide neural development, provide signaling 'express route'

Science Daily - 03/01/2024
Discover the first images of cytonemes during mammalian neural development, serving as express routes to establish morphogen gradients and tissue patterning.

Calcium channel blockers key to reversing myotonic dystrophy muscle weakness

Science Daily - 03/01/2024
New research has identified the specific biological mechanism behind the muscle dysfunction found in myotonic dystrophy type 1 (DM1) and further shows that calcium channel blockers can reverse these symptoms in animal models of the disease. The researchers believe this class of drugs, widely used to treat a number of cardiovascular diseases, hold promise as a future treatment for DM1.

Influencers' vulnerabilities: A double-edged sword

Science Daily - 03/01/2024
New research finds that social media platforms and the metrics that reward content creators for revealing their innermost selves to fans open creators up to identity-based harassment.

Designing the 'perfect' meal to feed long-term space travelers

Science Daily - 03/01/2024
Imagine blasting off on a multiyear voyage to Mars, fueled by a diet of bland, prepackaged meals. As space agencies plan for longer missions, they're grappling with the challenge of how to best feed people. Now, researchers have designed the optimal 'space meal': a tasty vegetarian salad. They chose fresh ingredients that meet male astronauts' specialized nutritional needs and can be grown in space.

Aptamers: lifesavers; ion shields: aptamer guardians

Science Daily - 03/01/2024
Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as well as ability to inhibit specific enzymes or target proteins through three-dimensional binding. They also hold promise for swift diagnoses of colon cancer and other challenging diseases by targeting elusive biomarkers. Despite their utility, these aptamers are susceptible to easy degradation by multiple enzymes, presenting a significant challenge.

Ants recognize infected wounds and treat them with antibiotics

Science Daily - 03/01/2024
The African Matabele ants are often injured in fights with termites. Their conspecifics recognize when the wounds become infected and initiate antibiotic treatment.

Reducing inequality is essential in tackling climate crisis, researchers argue

Science Daily - 03/01/2024
Promoting climate-friendly behaviors will be more successful in societies where everyone has the capacity: financially, physically, and time-wise, to make changes.

A novel switch to turn genes on/off on cue, a promising step toward safer gene therapy

Science Daily - 03/01/2024
Just like a doctor adjusts the dose of a medication to the patient's needs, the expression of therapeutic genes, those modified in a person to treat or cure a disease via gene therapy, also needs to be maintained within a therapeutic window. Staying within the therapeutic window is important as too much of the protein could be toxic, and too little could result in a small or no therapeutic effect. Researchers now report on a technology to effectively regulate gene expression, a promising solution to fill this gap in gene therapy clinical applications.

First step towards synthetic CO2 fixation in living cells

Science Daily - 03/01/2024
Three modules forming a new-to-nature CO2 fixation cycle have been successfully implemented in E.coli.

'Nutritional quality must be at the heart of climate smart agriculture' -- researchers

Science Daily - 03/01/2024
Farmers in sub-Saharan Africa need to diversify away from growing maize and switch to crops that are resilient to climate change and supply enough key micronutrients for the population, according to a major research study. Maize is a staple crop across the region -- where it is grown and consumed in vast quantities.

Healthy omega-3 fats may slow deadly pulmonary fibrosis

Science Daily - 03/01/2024
Higher levels of omega-3, the healthy fat found in fish and nuts, were associated with better lung function and longer transplant-free survival.
