Nanoplastics can disrupt human liver and lung cell processes in lab experiments
What happens when people unknowingly eat, drink or inhale nearly invisible pieces of plastic? Although it's unclear what impact this really has on humans, researchers have now taken a step toward answering that question. In Environmental Science & Te.....»»
SpaceX shuts down launches after problem with Crew-9 mission"s 2nd stage
SpaceX celebrated the first human spaceflight from its Cape Canaveral launch site on Saturday, and while the two humans aboard the Crew Dragon Freedom are safely on their way to the International Space Station, a problem arose with the rocket's secon.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Water flux recovers asynchronously after snow damage in subtropical forest, study shows
Forests play a crucial role in the global water cycle. However, only a few studies have investigated post-damage radiative forcing of evapotranspiration and its underlying processes in forests......»»
Advancing green chemistry: A tandem catalyst for efficient biomass conversion
The global demand for sustainable energy sources has intensified the search for environmentally friendly alternatives to fossil fuels. Biomass waste, a byproduct of various industrial processes, presents an untapped potential for the production of bi.....»»
Shedding light on a decades-old protein sorting mystery
Christian de Caestecker, a Ph.D. student in the lab of Ian Macara, Louise B. McGavock Professor and chair of the Department of Cell and Developmental Biology, has proposed and validated a mechanism that addresses a decades-old mystery surrounding epi.....»»

Completed experiments on International Space Station to help answer how boiling and condensation work in space
After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA's Glenn Research Center in Cleveland designed, built and tested has completed its test campaign on the International Space Station......»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Key negotiator Norway sees "positive signals" ahead of plastic talks
In the single week that world leaders convened for high-level UN talks in New York, nearly 100,000 water bottles' worth of microplastics swirled through the city's air, posing known and still unknown risks to human health......»»
Improving industrial scale lactoferrin production with synthetic biological systems
Lactoferrin (LF), a multifunctional glycoprotein of the transferrin family, is naturally expressed in human and cow milk. The name "LF" is derived from its ability to bind to iron (ferrin, a suffix indicating iron-binding protein)......»»
Tesla Full Self Driving requires human intervention every 13 miles
It gave pedestrians room but ran red lights and crossed into oncoming traffic. Enlarge / An independent automotive testing company has evaluated Tesla FSD, and it found some concerning results. (credit: PonyWang/Getty Images).....»»
Why do people breach their bail? Research shows it"s not because they"re committing more crimes
In Australia and most countries, everyone is innocent until proven guilty. Because of this, keeping someone in detention before trial comes with serious legal, practical and human-rights consequences, not just for the person accused but also for thei.....»»
Murine study suggests cosmic radiation in outer space may affect long-term cognition
During missions into outer space, galactic cosmic radiation (GCR) will penetrate current spacecraft shielding and thus pose a significant risk to human health......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»

GM and Piston Automotive are plotting a hydrogen fuel cell factory in Detroit, GM's first standalone plant for fuel cell production......»»
Can the "hard steps" in the evolutionary history of human intelligence be recast with geological thresholds?
What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago, yet humans—the only intelligent, technological species we know of in the universe—have existed only for the last 200,0.....»»
