Researchers characterize regulating mechanism of orderly zygotic genome activation in early embryos

Researchers characterize regulating mechanism of orderly zygotic genome activation in early embryos

Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent work by Chinese scientists has revealed a novel molecular mechanism of how a totipotent chromatin is established and an orderly zygotic genome activation is controlled in early Drosophila embryos.

Human brain organelles study shows dopamine neurons must work a lot harder than those in primate relatives

Human brain organelles study shows dopamine neurons must work a lot harder than those in primate relatives

A team of neurologists, bioengineers and radiologists has found that two neurons in the human brain that code for dopamine production have to work harder than similar cells in primate relatives. The group has posted a paper describing their work on the bioRxiv preprint server.

Bee alert: Pesticides pose a real threat to more than 70% of wild bees

Bee alert: Pesticides pose a real threat to more than 70% of wild bees

A new study reveals alarming risks that pesticides pose to ground-nesting bees, which are crucial for pollination and food production. As agriculture increasingly relies on pesticides to protect crops, the unintended consequences for these essential pollinators are becoming clearer.

A single cell's siesta: How non-moving single-celled organisms manage to avoid bright light

A single cell's siesta: How non-moving single-celled organisms manage to avoid bright light

Too much of a good thing is no good at all. Living organisms enjoy sunlight—in fact, they need it to stay alive—but they tend to avoid light that is too bright. Animals go to their shelter, humans have a siesta, even plants have mechanisms to avoid an overdose of light. But how do non-moving single-celled organisms deal with light that is too intense? Researchers at the University of Amsterdam have discovered the surprising answer.

Citizen scientists help explain magenta aurora over Japan

Citizen scientists help explain magenta aurora over Japan

Citizen scientists in Japan enabled researchers to learn why May 2024's aurora appeared a magenta color over the country. This effort in extending research beyond academies and laboratories has greater consequences for humanity than explaining pretty lights.

First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago

First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago

Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a volcanic crater. These biomolecules, which came to be known as naphthocyclinones, are representative of a family of antibiotics with potential medical or biological applications. Despite their promising properties, artificially synthesizing these naphthocyclinones has proven to be quite challenging.

Simulations reveal black holes inherit magnetic fields from parent stars

Simulations reveal black holes inherit magnetic fields from parent stars

Black holes are one of the most enigmatic stellar objects. While best known for swallowing up their surroundings into a gravity pit from which nothing can escape, they can also shoot off powerful jets of charged particles, leading to explosive bursts of gamma rays that can release more energy in mere seconds than our sun will emit in its entire lifetime.
