Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
Scientists from six Asian countries have launched an ambitious 10-year effort to build synthetic cells from non-living molecules, marking the region's first coordinated push to create an artificial single-celled biological system. The roadmap, published on May 26 in Nature
Chemical reactions are the backbone to nearly all biological processes, including those used to make new medicines. However, these reactions can often take considerable time and require harsh conditions or materials—potentially inhibiting the timely development of life-changing
The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: Genes on the Y chromosome are critical for fertility in males. In a new study in the journal Current Biology, researchers at the University of Michigan
Laser systems operating in the 2-micrometer wavelength range open diverse opportunities in medical technology, agriculture, and plastics processing. In the Eurostars project DECOMP, Laser Zentrum Hannover e.V. (LZH) has developed novel fiber optic components that overcome
Our capacity for innovation, rather than being the work of random variation, is based on an intrinsic understanding of how the world works, claim Karolinska Institutet and Vrije Universiteit Amsterdam researchers in a new study published in the Proceedings of the National
The ocean is full of invisible workers. Trillions of microbes quietly break down carbon-containing organic matter, which helps to regulate Earth's climate. But scientists have long struggled to understand how different microbes contribute to the process.
In 2018, Caitlin Caspi started a five-year research project looking at how raising the minimum wage could impact nutrition-related health outcomes. Caspi is an associate professor of allied health sciences in the College of Agriculture, Health and Natural Resources (CAHNR),

Nylon is a representative plastic material used throughout our daily lives, from clothing to automobiles. However, most of its raw materials have been produced through petrochemical processes, resulting in large carbon emissions. KAIST researchers have developed a technology
Cells are typically studied outside the body under controlled laboratory conditions. However, conventional flat cell culture methods do not fully reproduce the complex three-dimensional environments that cells experience in living tissues. Tiny hydrogel capsules offer one way
Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to each other. This phenomenon has often been observed in small quantum systems
Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has extended a key temperature tool into the range most

The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom, scientists still debate why it persists despite its high costs. Even more mysterious is the loss of sex in favor of asexual reproduction whereby
The period between 2018 and 2022, sometimes referred to as "the rainbow wave," featured an unprecedented increase in LGBTQ candidates elected to office. Pete Buttigieg's rise from mayor of South Bend, Indiana, to U.S. secretary of transportation with a 2020 bid for president in
Applying an external magnetic field during the synthesis of CoFe2O4 electrocatalysts triples the ammonia yield during electrocatalytic conversion. The magnetic field alters the surface states of the spinel oxide thin films, making catalytically active sites more accessible. In
The latest production from the "molecular movie" imaging technology developed at Oregon State University is a new, inexpensive way of dealing with a common environmental pollutant. Based on short-pulse lasers, the imaging technology allows chemical and biological actions to be
4.5 billion years ago was an interesting time for Earth. The atmosphere was thick and what we would now think of as toxic. The moon, which was freshly formed, looks much more massive than it does today and faintly glows with the residual heat from its own creation. And the
