    Young rift flanks suggest Venus remains tectonically active

    Venus is an inhospitable place, with temperatures soaring to several hundred degrees Celsius (hundreds of degrees Fahrenheit) and no oceans like those on Earth. Planetary scientists long believed Venus was geologically dormant. However, recent research indicates that Venus remains geologically "alive" and even hosts active volcanoes.

    Drought, water shortages and crop failures: How does the medieval warm period compare with today?

    A heat wave lasting four months, followed by water shortages and crop failures. This is England in the 13th century, not the 21st. What is often called the Medieval Warm Period saw elevated temperatures in many parts of the world between the 10th and 13th centuries.

Though there has been an overall decrease in cannabis use among Minnesota adolescents over the past decade, prior studies have been limited in their ability to examine the nuances in this trend—particularly differences in use among social groups.

    Human sacrifice was deeply ingrained in Inca civilization. Children and young people were selected for sacrifice to appease the gods and sacred mountain spirits. Being chosen was considered a great honor for both the victims and their families. Now, research into the remains of three individuals sacrificed as part of an ancient Inca ritual is revealing new insights into how they died.

    How researchers are using AI to speed up drug discovery and development: Q&A

    Drug development is among the slowest, most failure-prone processes in modern science, with about 90% of drug candidates never reaching the market. Today, artificial intelligence methods have accelerated the first step—plucking promising molecules out of endless possibilities—but countless challenges remain. A successful drug must be not only safe and effective but also able to bypass the body's defenses and reach the right target.

In a new theoretical study, researchers from the Institute for Photonic Quantum Systems (PhoQS) at Paderborn University, in collaboration with researchers from the University of Arizona, have shown that exceptional points in nonlinear systems follow a universal geometric order—something that was previously unclear.

    Recoverable molecular helper guides synthesis of highly pure chiral rotaxanes

    Chiral molecules can exist in left- and right-handed forms. Although these mirror-image forms may look almost identical, they can behave very differently in chemical reactions, biological systems and advanced materials. Preparing one mirror-image form in high purity is therefore an important goal in chemistry.

    How an iceberg may have stopped emperor penguins from breeding on Coulman Island in 2025

    The number of chicks in the Coulman Island emperor penguin colony decreased by about 69% in 2025 compared with 2024, according to research published in Communications Earth & Environment. The authors suggest that a large iceberg, which grounded off the island between July 2025 and January 2026, likely restricted the colony's access to important foraging areas, demonstrating that individual iceberg movements may affect breeding success even when overall sea ice conditions appear favorable.

In Lake Malawi in East Africa, billions of lake fly larvae (Chaoborus edulis) make an unusual commute: By day, they sink more than 200 meters (656 feet) into the lake's oxygen-starved "dead zone" to hide from predators. By night, they rise to safely feed—but not before passing through a horde of waiting fish.

    Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed as the main consequence of climate change, humidity plays a crucial role in determining how much heat the human body can tolerate. When the air is already full of moisture, sweat evaporates less effectively, making it harder for people to cool down.
