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.
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.
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 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.
In the cell membrane, TRPM8 acts as a receptor for cold, enabling humans to sense cold. Researchers at Ludwig-Maximilians-Universitat have developed a photoswitchable TRPM8 channel activator based on the natural cooling agent menthol. This molecule called azo-menthol precisely controls TRPM8 channels using light. Azo-menthol can be switched ON and OFF with the precision of light.
