Advances in plate tectonics research provide a new view of deep Earth’s carbon emissions

Posted by in category: climatology

From time to time, when Earth’s tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from deep Earth may have affected the climate over the past billion years.

A new GPS system for microorganisms could enhance forensic investigations

Posted by in category: robotics/AI

A research team led by Lund University in Sweden has developed an AI tool that traces back the most recent places you have been to. The tool acts like a satellite navigation system, but instead of guiding you to your hotel, it identifies the geographical source of microorganisms.

Symmetry in biology: A look into how bees actively organize nests in mirroring patterns

Posted by in category: biological

Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies build symmetrical nests when they are placed on either side of a double-sided comb. The finding, published in Current Biology, extends examples of symmetry in biology to the behavior of communities and the architectural structures that they build.

Neuroimmune communication pathway reveals interactions that may drive endometriosis-associated pain

Posted by in category: biotech/medical

Boston Children’s Hospital and Harvard Medical School researchers have discovered a neuroimmune communication pathway that may drive endometriosis-associated pain and lesion growth.

Endometriosis is a debilitating inflammatory disease affecting up to 15% of women and is characterized by the growth of endometrial-like outside the uterus. Treatments can currently only target symptoms, with over-the-counter medicines and hormonal birth control, or in some cases, surgery.

Endometriosis occurs when cell tissues normally found within the uterus lining take root in areas outside the uterus. This tissue is hormonally sensitive and can become inflamed, especially during , and can cause severe cramping, pain, and other symptoms depending on the area affected.

Two companies to help Navy safeguard high-altitude sensitive electronics from electromagnetic pulse (EMP)

Posted by in categories: electronics, military

SAN DIEGO – U.S. Navy electronics experts are hiring two companies to develop enabling technologies to safeguard naval systems from the effects of high-altitude electromagnetic pulse (EMP).

Officials of the Naval Information Warfare Center Pacific in San Diego, announced estimated $12.5 million separate contracts Wednesday to Long Wave Inc. in Oklahoma City, Okla., and to Reliance Construction Co. in Cary, N.C., for high-altitude EMP hardening processes.

Laser, microwave, and other directed-energy weapons ready for the battlefield

Posted by in categories: drones, energy, military, surveillance

Perhaps no technology has shaped the 21st-century battlefield as profoundly as the drone. These uncrewed aerial vehicles (UAVs), along with their land and sea counterparts, have redefined the way wars are fought by providing military forces with unprecedented capabilities in surveillance, precision targeting, and intelligence gathering — all while reducing the risk to their own personnel. Drones have made complex operations more efficient and less costly, enabling militaries to strike with pinpoint accuracy and maintain a persistent presence over the battlefield.

As the century progresses, the influence of drones continues to expand beyond traditional state actors. Non-state groups and non-peer adversaries increasingly have adopted this technology, leveraging it to level the playing field in conflicts around the world. With commercial drones becoming more accessible, these actors can conduct reconnaissance, drop bombs, and challenge conventional military forces in ways that previously were unimaginable.

The influence of drones flows across all domains of warfare. Loitering munitions, or “Kamikaze drones,” have disrupted traditional force structures by providing smaller, more agile units with the ability to strike high-value targets such as tanks, artillery, and command centers.
