Phys.org / Sudden quantum jolts may not break adiabatic behavior after all
In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the system, work being action ...
Phys.org / Mechanochemistry simplifies synthesis of challenging conductive organic molecules
Mechanochemistry is a growing field for chemical reactions that proceed in the solid state in the absence, or with minuscule amounts, of solvent added. For decades, solvents have been considered conventional for the progression ...
Phys.org / The way a cell fails to divide after copying its DNA can determine its fate
Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction of a second. But things ...
Phys.org / How photosynthetic bacteria pass light along: Two major energy pathways identified
RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and ...
Phys.org / How temperature swings impact the growth of young songbirds
Climate change threatens to cause increasingly extreme and variable temperature swings, affecting everything from urban infrastructure to global food supplies. In the animal kingdom, the hardest hit may be the youngest and ...
Science X / Your hand betrays your sense of fairness, and it does so before you even realize it
It turns out that your body is much more truthful about what is and isn't fair than you might imagine. The rate at which we make physical movements is able to reveal whether our motives are self-interested or retaliatory.
Medical Xpress / Diabetes flips immune cells from repair to inflammation in peripheral artery disease, study finds
Type 2 diabetes can turn immune cells that help with tissue repair and anti-inflammatory responses into triggers of chronic inflammation. A recent study investigated why people with type 2 diabetes are at a higher risk of ...
Phys.org / Slower access, faster chemistry: Nanoreactor design improves catalysis by balancing molecular flow
A new study by a team at Tohoku University, published in Chemical Engineering Journal, has shown that more isn't always better when it comes to nanoscale chemical reactions. One might think that giving reactants completely ...
Phys.org / Stealth switch in tuberculosis enzyme could open route to drug-resistant treatment
Recent research published in Communications Biology marks an advance in structural biology by enhancing understanding of protein regulation mechanisms in Mycobacterium tuberculosis (Mtb), a global health threat. The team ...
Phys.org / A silent robot shadows sperm whales by listening to their clicks
An autonomous underwater glider is giving us a new and effective way to track sperm whales by tuning into their clicks and silently following them. To study these large oceanic predators, researchers need to monitor their ...
Phys.org / Room-temperature multiferroic could pave way to low-energy computing
A team of researchers at Rice University has engineered a new version of a well-known multiferroic that exhibits orders of magnitude higher performance at room temperature than its parent material. The study, published in ...
Phys.org / Under crushing hypergravity, fruit flies adapt—and recover
Expose an animal to extreme physical stress, and the expectation is simple: It will break down. But when UC Riverside scientists subjected fruit flies to forces many times stronger than Earth's gravity—a condition called ...
