Researchers reconstruct the genome of the common ancestor of all mammals

An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like this fossil animal, Morganucodon, which lived about 200 million years ago. Credit: Wikipedia by … Read more

NASA’s DART asteroid collision shown in newly released photos

Stunning images showing NASA’s DART spacecraft’s intentional collision with an asteroid were released Tuesday. The Italian Space Agency shared the first images snapped by the tiny camera trailing the vending-machine-sized spacecraft, the LICIACube — or  Light Italian Cubesat for Imaging of Asteroids. The images were transmitted seven million miles back to earth about three hours … Read more

Mysterious radio signal from deep space flashes Earth 2,000 times within 2 months – The US Sun

POWERFUL signals are being beamed in Earth’s direction from deep space at an unprecedented rate. According to scientists, a repeating fast radio burst source discovered last year was recorded firing more than 1,800 bursts our way within the space of two months. 1 Fast Radio Bursts are thought to come from powerful objects called magnetarsCredit: … Read more

Scientists Discover That Chromosomes Are Fluid

The study found that chromosomes are fluid, almost liquid, outside of their division phases. Chromosome manipulation in live cells indicates that they are fluid. Researchers from CNRS, the Curie Institute, and Sorbonne University have successfully physically acted on chromosomes in live cells for the first time. They found that, outside of cell division phases, chromosomes are actually … Read more

Quantum technology reaches unprecedented control over captured light

Illustration of the aluminum resonator to the right. The blue and red patterns show quantum mechanical states that the Chalmers researchers can create and control. Counting from the top to the bottom right, the states are: Gottesman-Kitaev-Preskill (GKP), Cubic phase state, Binomial state, Fock state and Cat state.

Study Shows Transmission of Epigenetic Memory Across Multiple Generations

Summary: By altering the epigenetic markers on chromosomes, researchers witnessed changed gene expression in offspring and grand-offspring. The findings reveal the occurrence of transgenerational epigenetic inheritance. Source: UC Santa Cruz Without altering the genetic code in the DNA, epigenetic modifications can change how genes are expressed, affecting an organism’s health and development. The once radical … Read more
