Chronic rhinosinusitis linked to depression, anxiety

Posted by in categories: biotech/medical, neuroscience

(HealthDay)—Chronic rhinosinusitis (CRS) is associated with incidence of depression and anxiety, according to a study published online Feb. 7 in JAMA Otolaryngology-Head & Neck Surgery.

Jong-Yeup Kim, M.D., Ph.D., from Konyang University Hospital in Daejeon, South Korea, and colleagues conducted a retrospective nationwide cohort study using population-based insurance data for 16,224 patients with CRS and 32,448 individuals without CRS, with propensity score matching between the groups. The incidence, survival rate, and hazard ratios of depression and anxiety were calculated for each group.

The researchers found that during the 11-year follow-up, the overall incidence of depression was higher in the CRS versus the non-CRS group (24.2 versus 16.0 per 1,000 person-years; adjusted hazard ratio, 1.54). Higher incidence of anxiety was also seen in the CRS versus the non-CRS group (42.2 versus 27.8 per 1,000 person-years; adjusted hazard ratio, 1.57). Compared with patients with CRS with nasal polyps, patients with CRS without had higher adjusted hazard ratios for developing depression (1.61 versus 1.41) and anxiety (1.63 versus 1.45).

Navy-Funded Scientist Wins Award for Groundbreaking Seafloor Map

Posted by in category: military

Dr. David Sandwell, a geophysicist at Scripps, has been awarded American Geophysical Union’s Charles A. Whitten Medal for creating the world’s first comprehensive, high-resolution map of the ocean floor.

In a long-running project sponsored by the U.S. Navy’s Office of Naval Research, Sandwell combined satellite data with sonar measurements to develop a global depth chart of unprecedented detail. His work has charted thousands of previously unidentified mountains, trenches, and other features in the deepest and least explored parts of the ocean. The work is not only of academic interest: it provides crucial intelligence and scientific information for the Navy.

“Dr. Sandwell’s groundbreaking work provides the first high-resolution map of the ocean floor,” said Dr. Tom Drake, head of ONR’s Ocean Battlespace and Expeditionary Access Department. “This has opened new research areas for oceanography, marine geology and geophysics — critical topics for the U.S. Navy.”

Research suggests life thrived on Earth 3.5 billion years ago

Posted by in category: evolution

This study provides some of the first information regarding how robustly ancient life was metabolizing. Microbial sulfate metabolism is recorded in over 3 billion years of sulfur isotope ratios that are in line with this study’s predictions, which suggest was in fact thriving in the ancient oceans. This work opens up a new field of research, which ELSI Associate Professor Shawn McGlynn calls “evolutionary and isotopic enzymology.” Using this type of data, scientists can now proceed to other elements, such as carbon and nitrogen, and more completely link the geochemical record with cellular states and ecology via an understanding of enzyme evolution and Earth history.

New Senescent Cell Biomarker Discovered

Posted by in category: life extension

Researchers have made progress on the road to effective biomarkers for senescent cells.

In aging research, there has long been a need for better biomarkers that can detect and confirm the presence of senescent cells. This has become particularly urgent in recent years due to the meteoric rise of the senescent cell-clearing therapies known as senolytics.

Traditional ways of measuring senescent cell populations are problematic and have multiple shortfalls, so the development of better biomarkers is very important. Today, we share a new publication in which researchers take a step towards developing such a biomarker [1].

Living on the Moon Could Happen Sooner than We Think

Posted by in categories: robotics/AI, space travel

In January, the deputy head of the CNSA Wu Yanhua explained that Chang’e 5 and 6 would serve as missions to return samples from the moon while Chang’e 7 will survey the South Pole, this lunar area is of great interest for human colonies since holds water ice. Yanhua added that they hope Chang’e 8 will be able to test out some technologies and explore the moon to determine how to build a joint lunar base that multiple countries can share.

Once again, China is not the only one who wants to send humans back to the Moon. Both NASA and the ESA have plans in the works. The ESA’s new director-general, Jan Woerner introduced plans for a permanent Moon base in 2016. His ideal ‘Moon village’ would be home to a diverse set of people such as scientists and artists, as well as public and private organizations. The lunar base would serve many purposes such as astronomical research, tourism, or mining minerals.

Ariel Ekblaw, the founder of the MIT Media Lab’s Space Exploration Initiative, is also looking to “democratize space.” Thus, he has formed multi-disciplinary research groups studying everything from robotics and synthetic neurobiology to architecture, art, space, and even design.
