Chromatin structure found to play a key role in canine social behavior evolution
A study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation......»»
Light-responsive gene regulation at the mRNA level
Researchers at the University of Bayreuth have established a new optogenetic approach that can control the bacterial production of proteins at the mRNA level using blue light. The new system gates the activation of the genetic substance particularly.....»»

New study unveils 16,000 years of climate history in the tropical Andes
A new study that explores ancient temperatures and rainfall patterns in the tropical Andes of South America has revealed how 16,000 years of climate history in this part of the world was driven by carbon dioxide levels and ocean currents from global.....»»
Unveiling the ancient Maya"s relationship to animals and nature
As the scorching May sun of Central Belize blazes down on us, temperatures soar to a staggering 106°F. Local farmers anxiously await the onset of the rainy season to sow their crops, but the much-needed first rain remains elusive. This property is o.....»»
Align or die: Revealing unknown mechanism essential for bacterial cell division
A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto "dying to align": Misaligned filaments "die" spontaneously to form a ring structure at the center of the dividing cell. The stud.....»»
Discovery of tiny bone sheds light on mysterious "hobbit" humans
The discovery of a tiny arm bone suggests that an ancient human dubbed "hobbits" only shrank down to their diminutive size after they arrived on an Indonesian island a million years ago, scientists said on Tuesday......»»
135-million-year-old marine crocodile sheds light on Cretaceous life
An international team of scientists, including researchers from Germany and the UK, have described a new species of ancient marine crocodile, Enalioetes schroederi. Enalioetes lived in the shallow seas that covered much of Germany during the Cretaceo.....»»
From fungi to pharmaceuticals: A milestone for the production of eutyscoparol A and violaceoid C
The natural world is rich in chemical compounds with remarkable medicinal properties. A notable example is penicillin, discovered by chance from the Penicillium mold. This discovery revolutionized the treatment of bacterial infections and highlighted.....»»
Research shows that glossy black-cockatoos prefer to feed from trees growing in acidic soils
Glossy black-cockatoos are seed-eating birds that feed almost exclusively on the cones of drooping sheoak trees. However, counter-intuitively, they select trees that grow on the poorest soils found on ancient sedimentary rocks......»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
