Phys.org / DNA's physical properties may shape which mutations evolution preserves
Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility ...
Phys.org / Interstellar travel IV: Solar, magnetic, & directed-energy sails
Welcome back to our series on interstellar travel! In our first installment, we examined attempts to realize nuclear propulsion and how the technology could be used to reach the nearest star. In our second, we examined how ...
Tech Xplore / Expert comment: New nuclear capacity won't fix today's energy problems
The Fukushima nuclear disaster on March 11, 2011, triggered by a tsunami and leading to multiple reactor meltdowns, shook confidence in nuclear safety well beyond Japan. In Germany, it was a turning point: Chancellor Angela ...
Phys.org / RNA droplets may have helped start life on Earth
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Phys.org / Universal pattern revealed in quantum matter
When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following ...
Phys.org / Why isn't the accounting profession more diverse? Research points to the real levers of change
For the past few decades, universities, employers and professional organizations worldwide have invested in mentoring programs, scholarships and student support initiatives to diversify careers such as professional accounting. ...
Phys.org / Interworld Slingshot: Exploring a new way to find resources in space
Before people can mine resources on the moon, asteroids or Mars, they need to answer a few key questions: What is there? How much is there? And where can it be found? A team led by SETI Institute research scientist Pablo ...
Phys.org / Krypton gas emerges as a new ingredient for quantum computing
To commercialize quantum computing, manufacturers need high-quality superconducting materials for microchips, but they also require a reliable, sustainable nanofabrication process. Tantalum is a corrosion-resistant metal ...
Phys.org / Mars attacks: How much dust from the red planet is safe to breathe?
NASA has released a report recommending an initial health standard for the Martian dust that astronauts could inhale during future missions. Although sending people to Mars is still years away, NASA needs to establish safety ...
Tech Xplore / Flash of light creates high-performance materials without heating the surface beneath
A flash of light lasting a fraction of a millisecond could help create better materials for solar energy. Researchers used ultrafast heating at rates of up to 10 million degrees Celsius per second to rearrange the atoms inside ...
Phys.org / New bone analysis challenges long-held theory on farming's arrival in Ireland and Great Britain
New research led by University College Dublin has rewritten a key chapter in Irish prehistory, revealing that bones long thought to mark the beginning of farming in Ireland belong to bear and wild boar, not cattle.
Phys.org / Dynamic surface reconstruction explains how copper sulfide catalysts tune CO₂ reduction
Copper sulfide (CuS) catalysts continuously reconstruct their surface during electrochemical CO2 reduction, reports a study from the Institute of Science Tokyo, Japan. By uncovering the mechanism behind the dynamic surface ...
