Today, researchers from Eindhoven University of Technology and University Paris-Saclay are defying a classical theory from American physicist Josiah Willard Gibbs, with proof of a five-phase equilibrium, something that many scholars considered impossible.
For many livestock species, artificial insemination (AI) is standard. But it can be tricky to achieve success the first time, thanks to variability in ovulation timing across the herd. A new University of Illinois study identifies a naturally occurring sugar that slows the maturation of sperm in pigs, opening up the possibility of extending sperm storage time within the female reproductive tract and increasing the chances of successful fertilization through AI.
Researchers at Uppsala University have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customising treatment of bacterial infections. The study is published in PLOS Biology.
Scientists have found that the "segmentation clock"--a genetic network that governs the body pattern formation of embryos--progresses more slowly in humans than in mice because the biochemical reactions are slower in human cells. The differences in the speeds of biochemical reactions may underlie differences between species in the tempo of development.
Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event of Bacteria and another single-celled organism known as Archaea. However, evidence of a transition period in which the two organisms mixed where nowhere to be found. That is, until now. In the deep waters of the Black Sea, a team of scientists from NIOZ and Utrecht University found microbes that can make membrane lipids of unexpected origin.
Colloidal particles have become increasingly important for research as vehicles of biochemical agents. In future, it will be possible to study their behaviour much more efficiently than before by placing them on a magnetised chip. A research team from the University of Bayreuth has discovered that colloidal rods can be moved on a chip quickly, precisely, and in different directions. A pre-programmed magnetic field even enables these controlled movements to occur simultaneously.
Researchers undertook a detailed study on green-to-red photoconversion (light-induced conversion) of the Green Fluorescent Protein (GFP). In their recent study, scientists from Skoltech and their colleagues describe the molecular mechanism of photoconversion in detail for the first time ever.
The eyes of the fruit fly are covered by a thin and transparent coating with anti-reflective, anti-adhesive properties. Researchers from the University of Geneva and Lausanne discovered that the coating only consists of two ingredients: retinin and corneal wax. They succeeded in artificially reproducing the phenomenon on different kinds of surface. This process, which is very inexpensive and is based on biodegradable materials, could have numerous applications for contact lenses, medical implants and textiles.
It is generally accepted that the inner region of the early solar system was subject to an intense period of meteoric bombardment referred to as the late heavy bombardment. However, researchers have found evidence that suggests this period occurred slightly earlier than thought and was less intense but also more prolonged. Such details about this period could impact theories about the early Earth and the dawn of life.
Researchers use discarded wound dressings as a novel and non-invasive way to study the mechanisms that promote healing.
