The discovery and development of new small-molecule compounds for therapeutic use involves a huge investment of time, effort and resources. Giving a new spin to conventional chemical synthesis, a team of researchers from the National University of Si.....»»
The birth of a subnanometer-sized soccer ball
Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important for the fundamental understan.....»»
Swiss farmers contributed to the domestication of the opium poppy
Fields of opium poppies once bloomed where the Zurich Opera House underground garage now stands. Through a new analysis of archaeological seeds, researchers at the University of Basel have been able to bolster the hypothesis that prehistoric farmers.....»»
Hydrogen peroxide-producing drug boosts cancer-killing effect of radiotherapy
A small drug molecule that appears to protect normal tissue from the damaging effects of radiation, may simultaneously be able to boost the cancer-killing effect of radiation therapy, according to a new study......»»
Low levels of a simple sugar -- A new biomarker for severe MS?
Researchers have discovered a sugar molecule whose levels are reduced in the blood of patients with particularly severe multiple sclerosis. Their discovery could pave the way for a new therapeutic approach......»»
Restricting growth, spread of head and neck cancers
Researchers have discovered a key molecule that allows cancer stem cells to bypass the body's natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhib.....»»
DNA-inspired "supercoiling" fibers could make powerful artificial muscles for robots
The double helix of DNA is one of the most iconic symbols in science. By imitating the structure of this complex genetic molecule we have found a way to make artificial muscle fibers far more powerful than those found in nature, with potential applic.....»»
Engineering single-molecule fluorescence with asymmetric nano-antennas
NIR fluorescence has shown great potential in bioscience, but low quantum-yield has largely impeded research on most NIR fluorophores. Here, scientists in China use asymmetric plasmonic nano-antennas to drastically enhance an NIR dye's single-molecul.....»»
Under pressure: Manipulating protein-mimicking molecules with hydrostatic pressure
Stimulus-responsive supramolecular structures have emerged as an alternative to conventional ones, owing to their applications in sensing, drug delivery, and switchable memory systems. Now, scientists at Tokyo Institute of Technology explore the hydr.....»»
Researchers create long-sought zigzag-edged carbon nanobelts
NUS chemists have developed a strategy for the atomically precise synthesis of fully conjugated zigzag-edged carbon nanobelts (CNBs). The obtained molecule, known as octabenzo[12]cyclacene, is acknowledged as one of the first fully characterized synt.....»»
New catalyst for lower carbon dioxide emissions
If the CO2 content of the atmosphere is not to increase any further, carbon dioxide must be converted into something else. However, as CO2 is a very stable molecule, this can only be done with the help of special catalysts. The main problem with such.....»»
Fan-made Sonic game for PS5 was created inside another game
