Phys.org / Does relativity lie at the source of quantum exoticism?
Since its beginnings, quantum mechanics hasn't ceased to amaze us with its peculiarity, so difficult to understand. Why does one particle seem to pass through two slits simultaneously? Why, instead of specific predictions, ...
Medical Xpress / Study overturns 'snapshot' model of cell cycle in use since 1974
Cells have a big decision: Should they replicate or sleep? Healthy cells can go either way. Cancer cells' replication switches are stuck in the 'on' position. Now a study by University of Colorado Cancer Center researchers ...
Phys.org / Bioengineering biomimetic human small muscular pulmonary arteries
During the progression of pulmonary hypertension, structural and functional changes in the small muscular arteries play a significant role and contribute to the disease. Bioengineers aim to develop advanced, anatomically ...
Medical Xpress / Tailoring an anti-cancer drug for optimal tumor cell killing
In a study published this week in Science, Université de Montreal researchers report key structural and biochemical differences among a class of anti-cancer drugs known as PARP inhibitors. These distinguishing differences ...
Phys.org / Technique reveals how crystals form on surfaces
The process of crystallization, in which atoms or molecules line up in orderly arrays like soldiers in formation, is the basis for many of the materials that define modern life, including the silicon in microchips and solar ...
Phys.org / Using chemistry to unlock the difference between cold- and hot-brew coffee
Cold brew may be the hottest trend in coffee-making, but not a lot is known about how this process alters the drink's chemical characteristics. Scientists now report that the content of potentially health-promoting antioxidants ...
Phys.org / Whooping cranes form larger flocks as wetlands are lost—and it may put them at risk
Over the past few decades, the critically endangered whooping crane (Grus Americana) has experienced considerable recovery. However, in a report appearing April 2 in the journal Heliyon, researchers found that habitat loss ...
Medical Xpress / Researchers find that nicotinamide may help treat fibrotic eye diseases and mitigate vision loss
Nicotinamide, a form of vitamin B3, can inhibit aggressive cell transformations during wound healing and may be key to the development of therapies to treat fibrotic eye diseases that impair vision, according to a new Mount ...
Medical Xpress / Natural sunscreen gene influences how we make vitamin D
Genetic variations in the skin can create a natural sunscreen, according to University of Queensland researchers investigating the genes linked with vitamin D.
Medical Xpress / Single mutation leads to big effects in autism-related gene
A new study in Neuron offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been ...
Phys.org / Repair instead of renew: Damaged powerhouses of cells have their own 'workshop mode'
If the energy supply of a cell is disturbed by damage, it can protect itself from functional losses and repair itself in a kind of workshop mode. That is the result of a new study conducted by Professor Dr. Aleksandra Trifunovic ...
Phys.org / Fossil skull casts doubt over modern human ancestry
Griffith University scientists have led an international team to date the skull of an early human found in Africa, potentially upending human evolution knowledge with their discovery.
