The interaction between a probing tip and an adsorbed molecule can significantly impact the molecular chemical structure. The tip-induced bond weakening, tilting, and hopping processes of a single molecule were investigated by sub-nanometre resolved tip-enhanced Raman spectroscopy (TERS). The C−O stretching mode is always redshifted as the tip approaches, revealing the weakening of the C−O bond. Further analyses of the vibrational Stark effect and TERS imaging suggest a delicate tilting of the adsorbed CO molecule.
An antibody in single-chain fragment variable (scFv) format that binds to the powerful opioid carfentanil was shown to reverse signs of carfentanil overdose in preclinical tests conducted by scientists at Scripps Research.

When we think of soil, most of us think of dirt on the ground. But a surprising amount of the planet’s soil thrives in the treetops of old-growth forests, high above terra firma.
The key to understanding proteins — such as those that govern cancer, COVID-19, and other diseases — is quite simple. Identify their chemical structure and find which other proteins can bind to them. But there’s a catch.
Light affects living organisms in many different ways: for example, plants orient their growth direction towards the sun, while circadian rhythms in humans are controlled by daylight.
Scandium-44 is a promising medical isotope for positron emission tomography (PET) imaging for identifying cancer, heart disease, and other conditions. Scandium-44 can be produced through the radioactive decay of titanium-44, but the challenge is to reliably separate scandium-44 from titanium-44 at hospitals. A new approach produces an isotope generator that is portable, uses facilities routinely available at hospitals, and works efficiently and reliably. This will enable medical staff to more easily use scandium-44 for PET scans and other applications.
Using the full capabilities of the Quantinuum H1-1 quantum computer, researchers from the Department of Energy’s Oak Ridge National Laboratory not only demonstrated best practices for scientific computing on current quantum systems but also produced an intriguing scientific result. By modeling singlet fission — in which absorption of a single photon of light by a molecule produces two excited states — the team confirmed that the linear H4 molecule’s energetic levels match the fission process’s requirements.
In chemical reactions, molecules transform from reactants into reaction products through a critical geometry called a transition state that lasts less than one millionth of one millionth of a second. Scientists recently captured a critical geometry using the ultra-high speed “electron camera” at SLAC. The research will help explain why reactions generate only specific reaction products.
Antiviral therapies are notoriously difficult to develop, as viruses can quickly mutate to become resistant to drugs. But what if a new generation of antivirals ignores the fast-mutating proteins on the surface of viruses and instead disrupts their protective layers?
Scientists from the National University of Singapore have successfully synthesised a special protein-mimic that can self-assemble into a pore structure. When incorporated into a lipid membrane, the pores permit selective transport of water across the membrane while rejecting salt (ions).
Viruses often mutate or hide themselves within cells. But by mimicking the way the immune system naturally deals with invaders, researchers reporting in ACS Infectious Diseases have developed a “peptoid” antiviral therapy that effectively inactivates three viruses in lab tests.
