New bioplastic degrades faster than paper

Scientists discover fastest degrading bioplastic material in seawater.

Researchers from the Woods Hole Oceanographic Institution (WHOI) have made a groundbreaking discovery: cellulose diacetate (CDA) is the fastest degrading type of plastic in seawater. This bioplastic, when modified using a technique called “foaming” to make it porous, degrades a staggering 15 times faster than solid CDA, outpacing even the decomposition rate of paper. This remarkable finding underscores the potential of bioplastics and innovative modifications to combat plastic pollution in our oceans.

A cost-effective catalyst to revolutionize hydrogen production

A low-cost palladium-based nanosheet

Researchers from the Tokyo University of Science developed a new catalyst called bis(diimino)palladium coordination nanosheets (PdDI). These low-cost palladium-based nanosheets perform as well as platinum in producing hydrogen. Created using a simple synthesis process with minimal precious metals, the nanosheets reduce metal usage and lower hydrogen production costs.

Our breathing affects our vision

Breathing shapes what we see.

A study from Karolinska Institutet in Sweden found that breathing influences pupil size. The pupil is smallest during inhalation and largest during exhalation. This effect is always present and doesn't require external stimuli. Breathing's impact on brain activity and cognitive functions suggests this could help regulate vision and attention.

Loneliness after losing a spouse, study

Persistent Loneliness After Spousal Loss, Despite Social Support

Researchers at Monash University found that losing a spouse causes one to feel more lonely and isolated despite support. Based on data taken from nearly 750 people who had lost their spouses, they found that loneliness and grief affected both genders similarly, with no significant differences based on wealth or health status.

A long-standing Jupiter’s cloud mystery solved

A misunderstanding about the composition of Jupiter’s clouds resolved.

A collaboration between amateur and professional astronomers has led to a major discovery about Jupiter's clouds, challenging a long-standing belief. Thanks to amateur astronomer Dr. Steven Hill, it’s now found that the clouds are not made of ammonia ice, but rather a mix of ammonium hydrosulphide and smog.
