Small Protein, Big Impact: Microprotein Discovery Offers Hope for Obesity and Aging

on
Researchers have uncovered a tiny but powerful protein that helps keep our cells’ energy factories humming – a discovery that could spark new approaches to tackling obesity and age-related decline. Scientists at the Salk Institute in La Jolla found that a  “microprotein”  in mouse fat cells plays a critical role in maintaining healthy  mitochondria , the structures that generate energy in our cells. By preserving mitochondrial function, this diminutive protein helps cells burn fuel efficiently, which in turn could influence body weight and the aging process. The findings shine light on how molecular biology connects to everyday health, opening the door to  science-backed strategies for better metabolism and longevity.

How does flowers look like to insects?

on
To the human eye, a garden in bloom is a riot of colour. Flowers jostle for our attention, utilising just about every colour of the rainbow. But of course, it is not our attention they need to attract, but that of insects, the perfect pollinating agents. And as these remarkable pictures show, there is more to many flowers than meets the eye - the human eye at least. Many species, including bees, can see a broader spectrum of light than we can, opening up a whole new world. The images, taken by Norwegian scientist-cameraman Bjorn Roslett, present a series of flowers in both natural and ultraviolet light, revealing an insect's eye view.







Ultraviolet light, invisible to us, uncovers colours and patterns which drawthem to the source of pollen and nectar - all hidden to humans without special equipment. This secret colour world was discovered in the Fifties and scientists realised that these distinct patterns were designed to act as "landing strips" or arrows, guiding the insects to the right spot. Because we cannot see UV light, the colours in these photographs are representational, but the patterns are real. via Dailymail.

You are quite welcome Arlene. There's a lot about insects we don't know still.
