(Press-News.org)
A new peer-reviewed article published in Big Earth Data presents a comprehensive roadmap for building an integrated Global Ground-Based Earth Observatory (GGBEO) to better tackle the escalating planetary environmental and climate crisis. The study argues that unifying existing ground-based, in situ, remote sensing, marine, and airborne observation networks is crucial for meeting the United Nations’ Sustainable Development Goals (SDGs) and for advancing climate science and societal resilience.

Abstract
To tackle the planetary environmental and climate crisis and meet the United Nations’ Sustainable Development Goals (SDGs), we must fully leverage the potential of Earth observations (EO). This involves integrating globally sourced data on the atmosphere, hydrosphere, cryosphere, lithosphere, along with ecological and socio-economic information. By harmonizing and integrating these diverse data sources, we can more effectively incorporate observational data into multi-scale modeling and artificial intelligence (AI) frameworks. This paper is based on discussions from the “Towards Global Earth Observatory” workshop held from May 8–10, 2023, organized by the World Meteorological Organization (WMO) and the Atmosphere and Climate Competence Center (ACCC), in collaboration with the Institute for Atmospheric and Earth System Research (INAR) at the University of Helsinki. The current state of EO and data repositories is fragmented, highlighting the need for a more integrated approach to establish a new global Ground-Based Earth Observatory (GGBEO). Here, we summarize the current status of selected in-situ and ground-based remote sensing observation systems and outline future actions and recommendations to meet scientific, societal, and economic needs. In addition, we identify key steps to create a coordinated and comprehensive GGBEO system that leverages existing investments, networks, and infrastructures. This system would integrate regional and global ground-based in situ and remote sensing systems, marine, and airborne observational data. An integrated approach should aim for seamless coordination, interoperable and harmonized data repositories, easily searchable and accessible data, and sustainable long-term funding.

Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots: microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each.
Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices.
Powered by light, the robots carry ...

CLEVELAND—Athletes are 2.5 times more likely than the general public to develop nail fungus, according to a study in the Journal of the American Academy of Dermatology. A condition that can disrupt training, change performance and end careers. However, until now, no thorough study has examined how nail fungus affects various sports.
Today, Case Western Reserve University and University Hospitals announced the launch of the first large-scale collaborative study focused on onychomycosis, a chronic fungal infection of the nails, among ...

When engaging in a political discussion, talking about what you oppose instead of what you support may make others more open to your views, according to research published by the American Psychological Association.
“In an era of deepening political polarization, our research offers a counterintuitive insight into how we can better communicate across ideological lines: Talk about what you oppose, not what you support,” said lead author Rhia Catapano, PhD, of the University of Toronto.
In a series of experiments involving more than 10,000 participants, the researchers examined how the way people talk about their opinions—specifically, ...

PULLMAN, Wash — Washington State University researchers have found a way to modulate a common virus protein to prevent viruses from entering cells where it can cause illness, a discovery that could someday lead to new antiviral treatments.
In the fundamental research, reported in the journal Nanoscale, the researchers in the School of Mechanical and Materials Engineering and the Department of Veterinary Microbiology and Pathology were able to find and block an important interaction at the molecular level that allows ...

There is currently a massive shortage of doctors in the NHS and international medical graduates are critical to addressing that, making up just over 40% of the nation’s medical workforce. Yet compared to those who qualified as doctors in the UK, relatively few international medical graduates rise through the medical ranks to achieve positions as either consultants or GPs.
A new three-year project, funded by the National Institute for Health and Care Research (NIHR), aims to identify the precise reasons behind that, exploring why some international medical ...

Doenjang is a traditional Korean fermented soybean paste made from meju—naturally fermented soybean blocks—mixed with salt and aged through long-term fermentation. Unlike Japanese miso, Korean doenjang does not use koji; its flavor develops entirely from the natural fermentation of meju. It is prepared via fermentation and aging with microbial cultures, which produce umami compounds that improve its palatability. While umami is a well-understood concept, kokumi—a term used to describe attributes ...

LOS ANGELES — Two Keck Medicine of USC hospitals – USC Norris Cancer Hospital and Keck Hospital of USC – have each received a Top Teaching Hospital award for outstanding achievement in patient safety and quality from The Leapfrog Group, a nonprofit national watchdog organization. It is the first time two hospitals within the health system have received this honor simultaneously.
“This award is one of the most competitive and ...

World-first research published today by University of Sydney scientists has uncovered a mechanism that may explain why glioblastoma returns after treatment, offering new clues for future therapies which they will now investigate as part of an Australian industry collaboration.
Glioblastoma is one of the deadliest brain cancers, with a median survival rate of just 15 months. Despite surgery and chemotherapy, more than 1250 clinical trials over the past 20 years have struggled to improve survival rates.
Published in Nature Communications, the study shows that a small population of drug-tolerant cells known as “persister cells” rewires its metabolism ...

If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis, as researchers at the University of Basel have shown in trials with mice. However, their results also open up opportunities for treatments that make use of the microbiome.
When the immune system confuses friend and foe, autoimmune diseases develop. In the case of multiple sclerosis (MS), it mistakenly attacks the body’s protective layer of nerve fibers, known as the myelin sheath. Those affected can experience exhaustion ...

New York, NY [December 15, 2025] —Scientists at the Icahn School of Medicine at Mount Sinai have developed a novel artificial intelligence tool that not only identifies disease-causing genetic mutations but also predicts the type of disease those mutations may trigger.
The method, called V2P (Variant to Phenotype), is designed to accelerate genetic diagnostics and aid in the discovery of new treatments for complex and rare diseases. The findings were reported in the December 15 online issue of Nature Communications [DOI: 10.1038/s41467-025-66607-w].
Current genetic analysis tools can estimate whether a mutation is harmful, but they cannot determine ...
