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 ...
Tech Xplore / Giving drones a sense of 'pain' could help them predict instability before it happens
Imagine you're running and you sprain your ankle. The pain makes you gingerly limp the rest of the way home. This is a great example of how nature adapts to failures in a system. The pain tells you: "If you continue running ...
Phys.org / Conservation genomics faces growing calls to center Indigenous knowledge and data rights
Throughout human ecological history, we have played a variety of roles within ecosystems around the world. In this so-called Anthropocene era, genomic innovations have given us new and powerful ways to influence the environment ...
Phys.org / Diffractive networks enable optical information transfer through random and unknown diffusers
The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or diffusive medium, such ...
Phys.org / Hidden role of garnet reveals how Earth's 660-km seismic boundary forms
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle ...
Medical Xpress / BCG vaccine may rewire brain immunity, shift Alzheimer's markers over 12 months
New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine—which is delivered through the skin to prevent tuberculosis—may remodel the human brain's immune environment, ...
Tech Xplore / Blame the model, not the machine—better data helps 3D-printed metamaterials match predictions
Additive manufacturing, such as 3D printing, provides an excellent opportunity to design metamaterials: materials with an engineered structure that leads to desired properties such as, for instance, resistance to vibrations. ...
Phys.org / Instant digital rewards may make hard thinking feel less worthwhile
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward ...
Phys.org / Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits ...
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 / 'Polypill' for heart failure cuts hospitalizations and ER visits by 60% in trial
A "polypill" combining three medications recommended to treat heart failure into a single daily dose proved far more effective for patients than taking the drugs separately, a randomized clinical trial led by UT Southwestern ...
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 ...
