Phys.org / Synchronized infrared lasers control molecular shape changes and expose hidden fingerprints

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different ...

Phys.org / Single ion maps 3D electromagnetic fields above chips with record sensitivity

Researchers at ETH Zurich have developed a method that uses a single ion to detect electromagnetic fields above a surface and to create a three-dimensional map of them. In the future, this approach can be used to improve ...

Phys.org / How signals in the embryo tell cells what to become: A lab's final discovery

Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan Kettering Institute Developmental Biology Chair Kathryn Anderson, Ph.D., is publishing its final study.

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 / 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 / The broader a fungus's diet, the better it kills insects and helps plants

Many fungi lead triple lives—acting as deadly insect pathogens, decomposers in the soil, and helpful partners living inside and transferring insect-derived nitrogen to plant roots. Scientists have long wondered what allows ...

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 / 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 / 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 / Prescribed burns may generate over 20% of fine particle pollution in southeastern US

Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
