Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucat n Peninsula of Mexico triggered the extinction of all known non-bird dinosaurs. But for the early ancestors of today's waterfowl, surviving that mass extinction event was like ... water off a duck's back. Location matters, as Antarctica may

Based on the current pledges of countries for limiting their emissions of greenhouse gases, global temperatures are projected to reach 2.7 degrees Celsius beyond pre-industrial levels by the end of this century. A new review paper highlights how this would dramatically reshape the Arctic, the fastest-warming region of Earth. In 2024, annual average global air

Where lies the origin of the Indo-European language family? Researchers contribute a new piece to this puzzle. They analyzed ancient DNA from 435 individuals from archaeological sites across Eurasia between 6.400--2.000 BCE. They found out that a newly recognized Caucasus-Lower Volga population can be connected to all Indo-European-speaking populations. Where lies the origin of the
Food scientists are working to make pancakes healthier by boosting the popular morning favorite's nutritional value while enhancing its taste and texture. Generally, pancakes are made with refined flours, contributing to empty calories. The scientists want to make tasty pancakes with whole grains that add some fiber and protein. Typical breakfast pancakes are soft, fluffy
The microalga Nannochloropsis oceanica holds potential as a valuable source of sustainably produced nutrients such as protein, omega-3 fatty acids, and vitamin K2. A new study shows that cultivation conditions, particularly temperature and light, play a significant role in the yield. The world is searching for sustainable solutions for future food production, and microalgae appear
A new study proposes a framework for understanding living matter as a cascade of machines making machines, extending from the atomic scale to the scale of the entire biosphere. What is life?-This remains the quintessential puzzle of biological sciences, a question that embodies the intricate complexity and stunning diversity of life forms. This study suggests
Current optical and electron microscopy imaging techniques are not suited for measuring the dynamic characteristics of living microorganisms at tiny scales due to complex sample preparation methods or resolution or speed constraints. To address this issue, a team of researchers adapted the high-speed atomic force microscopy (HS-AFM) technique to capture nanoscale physical and mechanical data
This week, the world's governments are meeting in Geneva for the 78th meeting of the Standing Committee of CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora. CITES is the main agreement that regulates international wildlife trade, which is critical to ensuring that trade does not damage the status of
Many U.S. forests are privately owned, particularly in the Eastern and North Central part of the country. This makes control of invasive plants and pests challenging because efforts must be coordinated across landowners. A new study explores how differences in ownership motivation affects willingness to control, and how economic incentives can be implemented most efficiently.
Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. Researchers report evidence that marine nutrient cycles -- essential for sustaining ocean ecosystems -- are changing in unexpected ways as the planet continues to warm. Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in
Painted lady butterflies are world travelers. The ones we encounter in Europe fly from Africa to Sweden, ultimately returning to areas north and south of the Sahara. But what determines whether some butterflies travel long distances while others travel short distances? Scientists show that the different migration strategies are shaped by environmental conditions rather than
Scientists have created genetically-engineered mice that could help accelerate anti-aging research. Washington State University scientists have created genetically-engineered mice that could help accelerate anti-aging research. Globally, scientists are working to unlock the secrets of extending human lifespan at the cellular level, where aging occurs gradually due to the shortening of telomeres-the protective caps at the
Recyclers, battery manufacturers, and electric vehicle manufacturers must work together to revolutionize lithium-ion battery (LIB) recycling processes to meet ever-growing demand for electric vehicles (EVs) and energy storage systems.

New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2 degrees Celsuis above preindustrial levels. For those aged over 60, the same 2 degree rise would see more than a third of the
