Sandalwood oil by-product prevents prostate cancer development in mice      (via sciencedaily.com)     Original source 

Sandalwood oil has been used worldwide for centuries. Now, a study is the first to demonstrate in vivo the chemo-preventive properties of a by-product of the oil in a mouse model. Results show administering alpha-santalol reduced visible prostate tumors, protected the normal tissue, and delayed progression from a precancerous condition to a high-grade form of cancer. These findings are significant because mortality in prostate cancer patients is mainly attributable to advanced stages of the disease.

New research uncovers biological drivers of heart disease risk      (via sciencedaily.com)     Original source 

Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.

New approach to tackling bacterial infections identified      (via sciencedaily.com)     Original source 

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.

Researchers discover key to molecular mystery of how plants respond to changing conditions      (via sciencedaily.com)     Original source 

A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.

Direct view of tantalum oxidation that impedes qubit coherence      (via sciencedaily.com)     Original source 

Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
