Future quantum computers could be based on electrons floating above liquid helium, according to study by a RIKEN physicist and collaborators, appearing in Physical Review Applied.
Stanford materials engineers have 3D printed tens of thousands of hard-to-manufacture nanoparticles long predicted to yield promising new materials that change form in an instant.
Researchers in the US have developed a synthetic molecular structure called the Ribo-T, and it can be placed inside a living cell to produce specialised proteins and enzymes at almost the same efficiency as an actual ribosome.
Found inside all living cells, ribosomes are dense, complex structures that catalyse a constant stream of protein chains by linking amino acids together in the order specified by messenger RNA (mRNA) molecules. These cellular workhorses are basically in charge of decoding your DNA, and now scientists have manufactured a molecular device that can not only produce protein chains in a test-tube almost as well as a real ribosome, but can also churn out enough protein in bacterial cells without any natural ribosomes to keep them alive.
The team, with researchers from the University of Illinois at Chicago and Northwestern University, says not only will the Ribo-T help them to better understand how our own ribosomes function, but it could lead to more effective drugs and next-gen biomaterials, with these little protein factors churning out whatever we need.
Once believed to be indiscriminate gene translators, ribosomes have been found to play critical roles in cell development and function.
Whether through genetics or training, scientists say, even mere mortals can develop extraordinary abilities.
IBM has created a quantum error-correcting code about 10 times more efficient than prior methods.

Researchers find large language models use a simple mechanism to retrieve stored knowledge when they respond to a user prompt. These mechanisms can be leveraged to see what the model knows about different subjects and possibly to correct false information it has stored.
Diamond is a promising material for the biomedical field, mainly due to its set of characteristics such as biocompatibility, strength, and electrical conductivity. Diamond can be synthesised in the laboratory by different methods, is available in the form of plates or films deposited on foreign substrates, and its morphology varies from microcrystalline diamond to ultrananocrystalline diamond. In this review, we summarise some of the most relevant studies regarding the adhesion of cells onto diamond surfaces, the consequent cell growth, and, in some very interesting cases, the differentiation of cells into neurons and oligodendrocytes. We discuss how different morphologies can affect cell adhesion and how surface termination can influence the surface hydrophilicity and consequent attachment of adherent proteins.
