Phys.org / Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination
In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked ...
Phys.org / Scientists uncover why Antarctica became engulfed by ice millions of years before the Arctic
Scientists have uncovered why Antarctica became engulfed by ice millions of years before the Arctic. The international research, published in Science, helps solve one of climate science's longest-standing puzzles: how a vast ...
Medical Xpress / Dynamic protein behavior drives blood-brain barrier specialization, study reveals
A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC), in collaboration with the Proteomics Platform of the Institute for Research in Biomedicine (IRB Barcelona), has uncovered a key mechanism ...
Phys.org / Microtubules in ovarian cell bridges may be key to fertility
Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these follicles, the oocyte is surrounded by granulosa cells that supply nutrients, signaling molecules and ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Phys.org / How giant tropical trees transport water 70 meters to stay as drought-resilient as smaller trees
The giant trees of tropical forests are important allies in the fight against climate change because of their ability to store carbon, yet they are still poorly understood by science. However, a study published in the journal ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
Phys.org / Quantum properties of multimode light observed despite extreme losses
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. ...
Medical Xpress / Common mucus-clearing treatments don't help ICU patients breathe easier and may cause harm, clinical trial finds
For patients struggling to breathe because of acute respiratory failure, clearing mucus from the airways is a routine part of treatment. Mucoactive agents are widely used for this purpose. But after years of clinical use, ...
Medical Xpress / Long sitting bouts linked to increased cancer risk
Each additional hour of prolonged, uninterrupted sedentary behavior in a person's day is associated with a 9% higher risk of cancer death, according to a study published in PLOS Medicine by Frederick Ho of the University ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
Phys.org / Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic ...
