Breakthrough in glioblastoma treatment with the help of a virus      (via sciencedaily.com)     Original source 

Researchers are describing the results of a recent clinical trial -- a breakthrough in glioblastoma treatment with the help of a modified cold virus injected directly into the tumor. When combined with an immunotherapy drug, the authors observed a subset of patients that appeared to be living longer as a result of this therapy.

Researchers describe the melting of gold nanoparticles in gold-bearing fluids in the Earth's crust      (via sciencedaily.com)     Original source 

Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold --regarded as the noblest of metals-- has been a symbol of splendour and wealth in many civilizations. Historically, gold deposits were known to form when metal was transported dissolved by hot aqueous solution flows --hydrothermal fluids-- until it accumulated in some areas in the Earth's upper crust. The recent discovery of gold nanoparticles in such mineral deposits has brought some doubts on the validity of the classical model.

All-electric rideshare fleet could reduce carbon emissions, increase traffic issues      (via sciencedaily.com)     Original source 

Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.

Climate change: Rising rainfall, not temperatures, threaten giraffe survival      (via sciencedaily.com)     Original source 

Giraffes in the East African savannahs are adapting surprisingly well to the rising temperatures caused by climate change. However, they are threatened by increasingly heavy rainfall, as researchers have shown.

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.

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).

Taurine may be a key to longer and healthier life      (via sciencedaily.com)     Original source 

A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.

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.

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.

Colorful fresh foods improve athletes' vision      (via sciencedaily.com)     Original source 

Nutrition is an important part of any top athlete's training program. And now, a new study proposes that supplementing the diet of athletes with colorful fruits and vegetables could improve their visual range. The paper examines how a group of plant compounds that build up in the retina, known as macular pigments, work to improve eye health and functional vision.
