Scientists Observe Sperm Defying a Fundamental Law of Physics

Image from pixabayAccording to a recent study, human sperm use their slender tails to navigate through thick fluids, appearing to defy Newton's third law of motion. This research also examines the movement patterns of these sex cells alongside single-celled algae.Exploring Non-Reciprocal Interactions in Microscopic SwimmersKenta Ishimoto, a mathematical scientist at Kyoto University, and his...

Scientists Show How Sperm and Egg Unite Like a Key in a Lock

This microscope image provided by Osaka University and the Research Institute of Molecular Pathology in October 2024, shows the fertilization of a mouse egg marked in red and green. DNA is marked in blue, showing in the egg at the top and in a sperm cell at the bottom left. Credit: Yonggang Lu/Osaka University/IMP...

Innovative Nanopillars Pierce The Nuclei Of Human Cells

A scanning electron microscope image of a cell sitting atop the nanopillarsAli SarikhaniResearchers have discovered a way to pierce the nucleus of a cell without damaging the rest of its structure, similar to puncturing the yolk of an egg without breaking the white or the shell. This breakthrough could have significant implications for medical...

New Research Unveils: The Impact of a Father’s Diet Before Conception on Child Health

Researchers have found that a father's diet before conception greatly affects his children's health. The artwork shows an allegorical fertilization scene where a fat sperm (colored yellow to symbolize fat) meets the egg (represented as the moon in a starry sky) and lights it up by passing on diet-induced genetic information.Recent research has highlighted...

How does a Small Fern Has Genome 50x Larger Than Humans

A small fern, found only on a few Pacific islands, contains over 100 meters of DNA in each cell, more than any known organism. "The fern, known as Tmesipteris oblanceolata, has round structures that produce spores", says Oriane Hidalgo.A printed version of the entire human genome would fill 220 large books. However, printing the...

What about Heart Health Threatened by Microplastic Pollution ?

How do Microplastic bits affect the heart? A small study from Italy looked into this by checking if these minuscule plastic particles, mostly too small to see (called nanoparticles), were in the artery plaque of the people they studied. The researchers studied 257 individuals who underwent surgery to clear clogged blood vessels. They examined...

Progress on HIV Vaccine?
