Nanorings: New building blocks for chemistry      (via sciencedaily.com) 

Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.

Learning how to control HIV from African genomes      (via sciencedaily.com)     Original source 

A study on almost four thousand people of African descent has identified a gene that acts as natural defense against HIV by limiting its replication in certain white blood cells. This research paves the way for new treatment strategies and underscores the importance of studying diverse ancestral populations to better address their specific medical needs and global health disparities.

Novel molecules fight viruses by bursting their bubble-like membranes      (via sciencedaily.com)     Original source 

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?

The key to battling a pathogen hides in its genome      (via sciencedaily.com)     Original source 

The availability, speed and effectiveness of genomic sequencing increased dramatically during the pandemic, as scientists worldwide rushed to find ways to track and predict the virus's movement and evolution. It also was critical in the development of effective vaccines. Biologists argue that building on this momentum is critical in society's response to future pandemics, but it requires significant collaboration and investment now, before the next pathogen is threatening society.

Deadly fungus beaten with new type of treatment      (via sciencedaily.com)     Original source 

Researchers have discovered a new way to attack fungal infections. The key is to block fungi from being able to make fatty acids, the major component of fats. Resistance to anti-fungal drugs is increasing and this new approach will be particularly useful because it works in a new way and affects a broad range of fungal species.

Scientists create novel approach to control energy waves in 4D      (via sciencedaily.com) 

Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.

When electrons slowly vanish during cooling      (via sciencedaily.com) 

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

Mutation accessibility fuels influenza evolution      (via sciencedaily.com)     Original source 

Scientists showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit.

How atomic nuclei vibrate      (via sciencedaily.com) 

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists report that they can thus confirm the wave-like movement of nuclear material more precisely that ever before and that they have found no evidence of any deviation from the established force between atomic nuclei.

'Swine flu' strain has passed from humans to swine nearly 400 times since 2009      (via sciencedaily.com)     Original source 

A new study of the strain of influenza A responsible for the 2009 H1N1 pandemic -- pdm09 -- shows that the virus has passed from humans to swine about 370 times since 2009, and subsequent circulation in swine has resulted in the evolution of pdm09 variants that then jumped from swine to humans.

How eavesdropping viruses battle it out to infect us      (via sciencedaily.com)     Original source 

Dozens of viruses -- at least -- can eavesdrop on host information. Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.
