As large-scale disasters—including earthquakes, torrential rains, typhoons and wildfires—become increasingly frequent, ensuring that pets as well as their owners can evacuate safely and receive appropriate care has become an important part of disaster preparedness.
Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are found in many biologically active natural products and
New research has revealed that ancient builders deliberately transported enormous 25-tonne stones across at least 18 kilometers (11 miles) to build Britain's tallest surviving prehistoric stone row—the iconic Devil's Arrows.
From repairing damaged tissues to developing better implants, many medical developments depend on materials that can mimic the complex properties of human tissue. Meta-biomaterials are among the most promising candidates. By tailoring their geometry, researchers can create
Halley's Comet captures the imagination in a way that few other astronomical objects do. When it last made its approach toward the sun (admittedly when this author, who is now middle-aged, was 1 year old in 1986), humanity responded with a fleet of spacecraft known informally
As Hong Kong Special Administrative Region's population ages at one of the fastest rates in the world, demand for family elder care increases daily. To understand the responsibilities and roles assumed by grandchildren in caring for their grandparents, the Asia-Pacific
A new study suggests that a period of intense fires and landscape upheaval in the ancient southern Levant may have helped create the conditions that led Neolithic communities to discover how fire could transform clay.

Researchers have developed a method for extrapolating sea surface temperatures from sparse data that is significantly more accurate than other commonly used computational methods and slightly more accurate than the best-performing AI model, while taking a fraction of the time
Across southern Europe, increasingly extreme heat, wildfire and intense rainfall are forcing planners to consider how one event can alter the risk of the next. Portugal's exceptionally wet winter and another summer of wildfire risk are an example of this. As a professor of
The work break room can be a place of rest, gossip, fun or recovery. But it can also be a cause for complaint when yesterday's fish dinner becomes a smelly microwaved lunch. For most people, microwaving fish at work is a big no-no. It has even led to armed confrontations.
An international team of astronomers has discovered the most distant progenitor to a galaxy supercluster ever. The discovery supports existing theories of how galaxy clusters evolve and reveals how they are connected to the larger cosmic web. The study relies largely on data
Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun. A new study based on high-altitude balloon measurements over
Plants are home to a diverse array of microorganisms that support their growth and help them adapt to environmental stress—of which there has been an abundance lately. High temperatures and drought caused by human-induced climate change have led to reduced crop yields and the
Melons produce many seeds, making the melon shape a traditional symbol of fertility and prosperity in Chinese culture. But the historical debate about how melons made their way to modern tables is as long and twisted as the vines they grow on.
