A nanotechnology treatment derived from bone marrow stem cells has reversed multiple sclerosis symptoms in mice and could eventually be used to help humans, according to a new study led by University of California, Irvine researchers. “Until now, stem cell therapies for autoimmune and neurodegenerative diseases have produced mixed results in clinical trials, partly [...]
In a paper published this week in Nature ("Freestanding crystalline oxide perovskites down to the monolayer limit"), materials science researchers at the University of California, Irvine and other institutions unveil a new process for producing oxide perovskite crystals in exquisitely flexible, free-standing layers. A two-dimensional rendition of this substance is intriguing to scientists and [...]
New research provides insight into the structure of silicon nanocrystals, a substance that promises to provide efficient lithium ion batteries that power your phone to medical imaging on the nanoscale. The research was conducted by a team of University of Alberta chemists, lead by two PhD students in the Department of Chemistry, Alyx Thiessen [...]
Several space missions, planned by both the European Space Agency and NASA, have their target set on Jupiter and its moons. The extraordinarily harsh radiation environments in the Jovian system will set some strict requirements for the electronics inside the spacecraft. To ensure the proper function of the spacecraft, it is important to understand [...]
The text of the video commentary: Elon Musk’s new project Neuralink has been making headlines recently, but very little is known about this mysterious company so far. We’re going to answer the question ‘What is Neuralink?’ and let you know why you should be paying very close attention. I’m Zachary Maslanik, [...]
rance is clamping down on a common food additive that has been shown to be carcinogenic in animal studies. The ban of titanium dioxide, announced by the French government last month, follows a review that could not rule out human cancer risks. The ban is just the latest chapter in a long-running debate on [...]
Today’s societies critically depend on electronic systems. Past spectacular cyber-attacks have clearly demonstrated the vulnerability of existing systems and the need to prevent such attacks in the future. The majority of available cyber-defenses concentrate on protecting the software part of electronic systems or their communication interfaces. However, manufacturing technology advancements and the increasing hardware [...]
Researchers of the Nanoscience Center (NSC) at the University of Jyväskylä, Finland, and in the Xiamen University, China, have discovered how copper particles at the nanometre scale operate in modifying a carbon–oxygen bond when ketone molecules turn into alcohol molecules. Modification of the carbon–oxygen and carbon–carbon bonds found in organic molecules is an important [...]
Cells in the body are wired like computer chips to direct signals that instruct how they function, research suggests (Nature Communications, “The cell-wide web coordinates cellular processes by directing site-specific Ca2+ flux across cytoplasmic nanocourses”). Unlike a fixed circuit board, however, cells can rapidly rewire their communication networks to change their behaviour. The discovery [...]
We may be able to detect cancer soon by simply peeing on a stick. - Cancer is an aberrant function of a normal cell, where the regulators of that cell's dividing are broken and the cell starts to divide without regulation. Left to its own devices, that dividing without regulation will overcome the [...]
