UC Santa Cruz to lead data collection center for major federal project on genetic underpinnings of neurological conditions

The UC Santa Cruz Genomics Institute will run the Data Coordination Center for the Scalable and Systematic Neurobiology of Psychiatric and Neurodevelopmental Disorder Risk Genes (SSPsyGene) Consortium. The team will coordinate an initial selection of 250 relevant genes from nearly 30,000 protein coding genes in the human genome.

Researchers track endangered Nassau grouper eggs with underwater microscope

Scientists tracked fertilized Nassau grouper eggs using an underwater microscope, finding that they stayed local in some years but drifted to nearby islands in others. The study reveals the importance of local reproduction and ocean currents in boosting populations and providing spillover benefits for neighboring islands.

Synthetic sRNAs to knockdown genes in medical and industrial bacteria​

Researchers at KAIST have developed a new sRNA tool that can effectively inhibit target genes in various bacteria, including both Gram-negative and Gram-positive bacteria. The BHR-sRNA system was shown to suppress pathogenicity in antibiotic-resistant pathogens and improve industrial strains for high-value-added chemical production.

Extracting the best flavor from coffee

A study published in Physics of Fluids reveals that uneven extraction in coffee brewing can result in weaker espresso and affect its taste. The researchers found that a positive feedback loop between flow and extraction leads to more bitter flavors, making it essential to understand the origin of uneven extraction.

The search for the origin of a rare tumor points to a poorly studied mechanism as a new would-be hot topic in cancer research: ‘succinylation’

Scientists at CNIO identify succinylation as a poorly studied mechanism in cancer research; mutated DLST protein prevents succinylation, leading to pseudohypoxia and tumor growth. Succinylation is crucial for protein function and may be linked to various diseases.

Lack of belief in body’s ability to function through pain linked to daily pre-surgery prescribed opioid use among candidates for elective spine surgery

A new Johns Hopkins Medicine study found that patients with low pain self-efficacy are more likely to use daily prescribed opioids before surgery. Surgeons can use pain self-efficacy scores to identify high-risk patients and provide education and counseling to improve post-surgery outcomes.

New study led by Brown researchers sheds light on incidental findings in lung cancer screening

A new study by Brown researchers found that 33.8% of patients with low-dose computed tomography (LDCT) screening had significant incidental findings, many of which were clinically important. The study suggests that standardizing reporting of these findings could improve patient care and reduce unnecessary medical interventions.
