Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Phys.org / How cells manage nitric oxide: Research uncovers dynamic 'gate' that tames powerful signaling molecule
Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain ...
Phys.org / Quantum computers go high-dimensional with a four-state photon gate
The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it possible to carry out ...
Phys.org / Between flood and drought: The metric that could better explain what happens to water in the age of climate change
A key question in any discussion about climate is "How much rain fell?" But perhaps there is an even more important one. Like any household budget, the global water economy is based on "income," that is, water entering the ...
Phys.org / From algae to biofuel: Study opens doors to cheaper, cleaner fuel sources
A researcher's keen eye and spirit of curiosity led to the discovery of a new method for cell engineering—a finding that opens doors to more sustainable sources for everything from fuel to vitamin supplements.
Phys.org / A new method reveals hidden rules of gene control
Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription ...
Dialog / Bringing quantum ideas to the messy world of disordered proteins
Imagine trying to design a key for a lock that is constantly changing its shape. That is the exact challenge we face in modern drug discovery when dealing with intrinsically disordered proteins.
Phys.org / Courtship is complicated, even in fruit flies
Love is in the air for the vinegar fly. Drosophila melanogaster has long been a model for understanding how brains translate sensory information into courtship behavior. Male flies perform a multitude of romantic actions—orienting, ...
Phys.org / Plant hormone therapy could improve global food security by balancing growth with immunity
Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there's a downside to this protective mechanism: the plant's growth is suppressed ...
Phys.org / Reading the enemy: How genome science is reshaping the fight against wheat stem rust
In 2013, farmers in the highlands of Ethiopia began to notice something unsettling: a familiar variety of wheat was failing in an unfamiliar way. Stems weakened, plants collapsed, and fields that had once held firm against ...
Phys.org / Stretchy plastics conduct electricity via tiny, whisker-like fibers
A stretchy, conductive type of plastic could help power the next generation of implantable biomedical devices, like longer-lasting pacemakers or glucose monitors, according to Enrique Gomez, professor of chemical engineering ...
Phys.org / How the echolocation of bats has shaped their skulls
Bats are some of the most highly specialized mammals to have ever evolved. This includes not only the evolution of active flight, but also their echolocation. This ability requires the bats to produce high frequency noises ...
