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 oak trees outwit their predators
Spring in the forest: Many insects, particularly caterpillars, hatch just when the trees' nutrient-rich leaves are still young and soft. This means they find a table laden with food and can start eating straight away. If ...
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 physics explanation shows why US elections keep ending 50:50—and why more spending won't change that
A physics-inspired model calibrated on 40 years of US congressional data pinpoints a spending threshold of roughly 1.8 million USD at which campaigns stop influencing who wins and start fueling polarization instead.
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 / 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 ...
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 ...
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 / Early brain regions play greater role in decision-making, challenging traditional neuroscience
New insight into decision-making pathways in the brain may impact the way engineers think about artificial intelligence, according to new research from The Grainger College of Engineering at the University of Illinois Urbana-Champaign. ...
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 / 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 ...
Medical Xpress / Reverse engineering ketamine's effects may lead to new antidepressants
Weill Cornell Medicine investigators have "reverse engineered" ketamine's antidepressant effects to identify potential new strategies for treating depression. While there are many effective treatments available for depression, ...
