Chemical shield stops DNA damage from tiggering disease–'A paradigm shift'

GOOD NEWS NETWORK - A new chemical probe protects healthy cells from DNA damage, preserving them from one of the 8 hallmarks of aging. The story of this potentially paradigmatic development begins where so much of human health begins: the mitochondria. These organelles are disrespectfully monikered as “the powerhouses” of the cell, but they do...

Chemical breakthrough shields mitochondrial DNA before damage triggers chronic disease

INTERESTING ENGINEERING - From Alzheimer’s to heart failure, many chronic diseases have been linked to damage in mitochondrial DNA (mtDNA). Now, scientists at the University of California, Riverside, may have found a way to halt the damage before it begins. The team has developed a chemical probe that targets damage in mitochondrial DNA (mtDNA), a...

Physicists learn to control electricity at the quantum scale

EARTH.COM - Today’s flagship processor packs more than 100 billion transistors, yet squeezing them any closer is turning design into a wrestling match with quantum physics. As the footprints of silicon switches approach the dimensions of a few dozen atoms, stray electrons tunnel across barriers that once looked rock‑solid, wasting power and scrambling signals. Physicists...

Scientists finally confirm the 'crazy' hypothesis about vitamin B1 from 1958

EARTH.COM - Scientists once dismissed a 1958 hypothesis about vitamin B1, or thiamine, as unlikely. The idea was that this vitamin, vital for basic metabolic functions, might turn into a very reactive intermediate during certain biochemical processes. Now, researchers have shown that the hunch was correct. Prof. Vincent Lavallo from the University of California, Riverside...

Super-shielded carbene is stable in liquid water

CHEMISTRY WORLD - A new ‘super-shielded’ carbene is stable in liquid water solutions. The US team that made the carbene claims that it ‘unambiguously confirms’ that it is possible to generate carbenes in an aqueous environment – validating a hypothesis put forward almost 70 years ago by the famed organic chemist Ronald Breslow. In the...

Scientists just confirmed a 67-year-old hypothesis about Vitamin B1

SCIENCEALERT - You often need a lot of patience to be a scientist, and that's certainly been the case for researchers who have now found solid evidence for a hypothesis around vitamin B1 (or thiamine) that was first put forward almost 70 years ago. In 1958, Columbia University chemist Ronald Breslow proposed that vitamin B1...

How Frequent Assessment Can Benefit URM Student Learning

INSIDE HIGHER ED - A pilot study at the University of California, Riverside, found that more regular testing, as opposed to high-stakes exams, can improve student outcomes in a general chemistry course and close equity gaps for historically disadvantaged learners. Assessment is a key element in higher education courses to track student learning, but some...

New light-activated salt treatment targets aggressive breast cancer with precision

STUDYFINDS - In the ongoing battle against aggressive breast cancer, light might become an unexpected ally. Scientists at Michigan State University (MSU) and the University of California, Riverside have engineered a remarkable new treatment that combines two unlikely partners, a specialized salt and near-infrared light, to target and destroy cancer cells while leaving healthy tissue...

New magnetic nanoparticles can safely rewarm tissues for transplants

INTERESTING ENGINEERING - In organ transplantation, time is of the utmost importance as organs’ quality degrades rapidly during transportation. Researchers at the University of California, Riverside, have developed a new technique that could extend the lifespan of human tissues for transplantation. ... In this new development, the researchers have developed a method to rapidly and...

‘Nanowarming’ process a game-changer for organ transplantation

NEW ATLAS - A new two-step process that safely rewarms frozen tissues using nanoscale magnetic rods could help preserve donor organs long-term. The procedure provides an alternative to current time-limited methods and paves the way for more life-saving transplantations. The gold-standard method for preserving organs prior to transplantation is static cold storage, which involves flushing...
