Eddies: Circular currents and their influence on the world's hottest ocean      (via sciencedaily.com)     Original source 

Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the Indian Ocean.

Researchers demonstrate noise-free communication with structured light      (via sciencedaily.com)     Original source 

Scientists used a new invariant property of vectorial light to encode information. This quantity, which the team call 'vectorness', scales from 0 to 1 and remains unchanged when passing through a noisy channel.

For pet dogs, 'running with the pack' may be the best prevention to promote healthier living      (via sciencedaily.com)     Original source 

The largest survey and data compilation of its kind --- from more than 21,000 dog owners --- has revealed the social determinants that may be tied to healthier aging for people's beloved canine companions. Among them, a measurement of the amount of a dog's social support network proved to have the greatest influence and association on better health outcomes -- 5 times the effect of financial factors, household stability or the age of the owner.

Mirror, mirror on the wall... Now we know there are chiral phonons for sure      (via sciencedaily.com)     Original source 

New findings settle the dispute: phonons can be chiral. This fundamental concept, discovered using circular X-ray light, sees phonons twisting like a corkscrew through quartz.

Why certain fish are left off the hook      (via sciencedaily.com)     Original source 

A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.

New research identifies cells linking chronic psychological stress to inflammatory bowel disease      (via sciencedaily.com)     Original source 

For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).

Lingering effects of Neanderthal DNA found in modern humans      (via sciencedaily.com)     Original source 

Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -- until now.

Lost giants: New study reveals the abundance decline of African megafauna      (via sciencedaily.com)     Original source 

A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.

A new way to develop drugs without side effects      (via sciencedaily.com)     Original source 

Have you ever wondered how drugs reach their targets and achieve their function within our bodies? If a drug molecule or a ligand is a message, an inbox is typically a receptor in the cell membrane. One such receptor involved in relaying molecular signals is a G protein-coupled receptor (GPCR). About one-third of existing drugs work by controlling the activation of this protein. Researchers now reveal a new way of activating GPCR by triggering shape changes in the intracellular region of the receptor. This new process can help researchers design drugs with fewer or no side effects.

Greenhouse gas emissions at 'an all-time high' -- and it is causing an unprecedented rate of global warming, say scientists      (via sciencedaily.com)     Original source 

Human-induced warming, largely caused by the burning of fossil fuels, reached an average of 1.14°C for the most recent decade (2013 to 2022) above pre-industrial levels. This is up from 1.07°C between 2010 and 2019. Human-induced warming is now increasing at a pace of over 0.2°C per decade. The analysis also found that greenhouse gas emissions were 'at an all-time high', with human activity resulting in the equivalent of 54 (+/-5.3) gigatonnes (or billion metric tonnes) of carbon dioxide being released into the atmosphere on average every year over the last decade (2012-2021). Given the speed at which the global climate system is changing, the scientists argue that policymakers, climate negotiators and civil society groups need to have access to up-to-date and robust scientific evidence on which to base decisions.
