Radioactive tadpoles reveal contamination clues

Tadpoles from an uncontaminated wetland were placed in a canal with releases of radiocesium from a nearby reactor, accumulating the contaminant at different rates. The study found that bullfrog tadpoles reached maximum threshold levels between 11-14 days, which is faster than previously studied species like waterfowl and fish.

Laser method promising for detecting trace chemicals in air

Researchers developed a mid-infrared picosecond laser-driven electron avalanche technique to detect electric charges and chemicals in air. They measured electron densities down to one part per quadrillion, equivalent to picking out one free electron from a million billion normal air molecules.

Upcycling process brings new life to old jeans

Researchers have developed an efficient and low-cost method to convert waste denim into reusable cotton fibers, reducing textile waste and conserving resources. The new process uses a 1:4 mixture of ionic liquid and DMSO to dissolve cellulose building blocks, resulting in white or colored viscose-type fibers.

Elemental old-timer makes the universe look like a toddler

Physicists at Rice University have reported the first direct observation of two-neutrino double electron capture for xenon 124, a process that decays into tellurium 124 with an estimated half-life of 160 trillion years. This discovery puts the half-life closer to 18 sextillion years, challenging our understanding of this isotope.

Plastic waste disintegrates into nanoparticles, study finds

A new study from Lund University investigates the degradation of plastic waste, finding that it can break down into nanoplastics under mechanical stress. The researchers warn that this could lead to adverse consequences for animals and humans, as nanoplastic particles are extremely small and can be ingested by living organisms.

Why are young adults wasting so much food? Study looks at perceptions and food behaviors

A study found that young adults, particularly college students, are high food wasters due to a lack of learned food management behaviors. The study's findings suggest that environmental factors, such as access to refrigerators and cooking facilities, also play a role in their behavior.

Tiny helpers that clean cells

Researchers have identified three known SNAREs and a new protein Ykt6 as essential for the fusion of autophagosomes with vacuoles, allowing for efficient cellular waste recycling. This breakthrough study sheds light on the molecular mechanisms underlying autophagy, a vital process in maintaining cellular homeostasis.

People waste nearly a pound of food daily

A new study finds that Americans waste nearly a pound of food per person each day, with the amount of wasted food corresponding to harvests produced using 780 million pounds of pesticide and 1.8 billion pounds of nitrogen fertilizer annually. The study also found that higher quality diets were associated with higher levels of food waste.
