Chemists want to reengineer metabolic proteins and pathways in microbes so they can convert sugar into commodity chemicals. Now a mutant protein found in cancer cells provides clues to help scientists improve a protein that could help microbes create a precursor to nylon. In science, as in so much of life, inspiration can come from unusual places.
Superhydrophobic surfaces enable simple water-based data storage and logic.
Most of our plastics come from petroleum-based chemicals. Now, thanks to engineered microbes, similar materials might be made using food waste from Starbucks.
Scientists are looking for elements and molecules that signify life as we know it. But even if they don’t find those molecules, minerals contain important information about the Martian environment. That could help scientists determine if life could have survived on the planet.
A new ordinance in Alameda County requires the pharmaceutical industry to pay for disposal of extra medicine. The regulation is part of a larger movement to shift responsibility for waste disposal from local governments to companies that make products like paint, medicine and batteries.
The source of the stench in crushed “stinkspar” is a 200-year old mystery. Solving this puzzle took a mixture of old-fashioned chemical analysis and modern instruments.
Conserving delicate artwork requires knowing what paints and techniques were used to create a piece. A new imaging technique helps restorers look at the pigments in frescos even while visitors are enjoying the works in a gallery.
Dogs have an amazingly sensitive sense of smell that allows them to find lost people, illegal drugs and even floating whale poop. A new sensor uses the same principles to sniff out rotten food.
