Falling birth rates reveal a deeper social problem: many people who want children feel blocked by economic, housing, gender, and climate pressures.

Earth’s energy imbalance has doubled—here’s why that matters
Heatwaves across Europe and South Asia have dominated the news recently. But these events are really a surface expression of more fundamental changes affecting our planet: Earth itself is accumulating heat faster than ever before.
We lead a large international team of scientists who come together every year to provide an update on the state of the climate system. This year, we find that Earth’s energy imbalance—the difference between the amount of energy entering and leaving the planet—has doubled in recent decades and is now at record levels.
This extra heat is a key indicator of the pace and scale of human-caused climate change. In a climate unaffected by human greenhouse gas emissions, Earth’s energy imbalance would be zero. But since the 1970s, Earth has become increasingly out of balance. This rate of increase is faster than expected, and work is underway to understand exactly why this is happening.
When the Virus Knows the Answer Before We’ve Asked the Question : How Scientists Are Learning to Forecast Pandemics Before They Happen
Climate change as the macro engine for viral emergence The BA.3.2 “Cicada” variant’s hidden evolution Yeast-display technology and viral forecasting Pan-coronavirus vaccine development at La Jolla Institute How conserved viral regions unlock universal defenses.
Scientists can now force a virus to evolve in a test tube — and predict a pandemic before it starts. Heliox explores the 2026 yeast-display breakthrough that reproduced Omicron’s exact mutations in just two generations, connects it to the climate-driven migration of bat populations worldwide, and asks: are we approaching the day when we vaccinate against a pandemic that hasn’t happened yet?
Scientists open a million-year-old time capsule hidden beneath New Zealand
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived.
Hotter Than a Hot Tub: The 45°C Breakthrough to Cool AI’s Biggest Machines
In favorable climates, NVIDIA’s 45-degree liquid-cooling architecture can enable chiller-less operation with dry coolers, reducing facility cooling water consumption from roughly 2.6 million gallons per megawatt per year for conventional cooling-tower-based systems to near zero — up to a 100% reduction in water use.
The reason: traditional air-cooled data centers depend on large volumes of cooled air to remove heat from IT equipment, often requiring energy-intensive cooling infrastructure during hot weather. With NVIDIA’s 45-degree liquid cooling, heat is captured directly at the chip and transported through liquid loops operating at much higher temperatures, allowing outdoor dry coolers to reject heat efficiently for much of the year while significantly reducing mechanical cooling requirements and facility water consumption.
The data center ambient temperature is flexible — warm summer air is fine — because nothing in the server depends on cool air. The liquid does all the work — and the same liquid can be recirculated in a closed loop so no new water is consumed to cool the chips.
NVIDIA’s latest AI servers can run on coolant warmer than a hot tub — and that counterintuitive choice is one of the biggest efficiency leaps in data center history.
Enhancing soil science research with multi-agent artificial intelligence systems
Soil science is entering a new era characterized by the integration of artificial intelligence (AI) multi-agent systems, extending the field beyond traditional machine learning (ML) applications such as digital soil mapping and spectroscopy. While current ML tools are effective for specific tasks, they often lack the reasoning, contextual integration, and adaptability required to address complex, dynamic soil systems. We propose multi-agent AI systems—autonomous, interactive software agents capable of perceptual processing, planning, and scientific reasoning—as a novel framework to support and accelerate soil science research. These agents can fulfill diverse roles, including synthesizing data from field sensors and remote sensing to create dynamic digital soil twins, generating hypotheses, designing experiments, and simulating climate-driven changes in soil function.
Richard H. Smith | Author of WhiteGrass — A Near-Future Climate Technothriller
Nanotechnology would make possible an all purpose utility belt.
This is a near-future where climate collapse is no longer theoretical, technology moves faster than ethics, and the most dangerous question is no longer can we save the planet?—but who gets to decide how?
WhiteGrass is a CliFi technothriller grounded in real science, real power structures, and deeply human consequences. It is a story about invention and control, about families forced into impossible choices, and about artificial intelligence that may be more morally awake than its creators.
Explore the characters, the science, and the ethical fault lines shaping a future that feels uncomfortably close.
Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on the time scale considered.
Led by Prof. Guy Dagan of the Fredy and Nadine Herrmann Institute of Earth Sciences, the research reveals that aerosol-cloud interactions can produce opposite climate effects in the short and long term. The findings, published in Nature Communications, offer a new explanation for why aerosols remain one of the largest sources of uncertainty in climate projections.
Aerosols come from a variety of natural and human-made sources, including air pollution, wildfires, sea spray and dust. Scientists have long known that these particles influence how clouds form and how much heat Earth retains, but accurately estimating their overall impact on climate has proved difficult.
Hidden meltwater found deep in Antarctic coastal waters reveals stronger climate impacts
Freshwater from melting Antarctic glaciers may be influencing the Southern Ocean in ways scientists have largely overlooked. New research, published in Frontiers in Marine Science, has found that glacial meltwater is not confined to the ocean’s surface, as previously assumed, but can also be detected much deeper in coastal waters along the Western Antarctic Peninsula.
The findings suggest that meltwater from glaciers is being transported and stored tens of meters below the surface, where it could alter ocean circulation, affect the movement of heat and nutrients, and influence how the region responds to climate change.
