Science, engineering, and discovery — the research and breakthroughs that matter.

Sunken treasure: Historic US ocean liner reborn as artificial reef and more — today's news signal.

A majestic and all but indestructible 20th-century ocean liner that once ferried royal leaders, movie stars and even the "Mona Lisa" to the United States was being deliberately sunk Wednesday to become the world's largest artificial reef.

With wars raging in Ukraine and across the Middle East, commentators increasingly ask whether we're sliding toward a third world war. But what makes a war "global"?

Bovine tuberculosis is evolving in different ways across different regions in Wales, according to the most detailed analysis of the bacterium conducted to date. One of the most significant animal health challenges facing Wales, bovine TB affects cattle health and farm businesses

Humans have left their mark on virtually every place on the planet, from the deep sea to the peaks of the highest mountains. But a few very remote atolls in the Pacific Ocean may be exceptions. A new Frontiers in Marine Science study has found two coral atolls, Bikar and Bokak, l

In arid regions, the microbes that power threatened dryland soil ecosystems called biological soil crusts stay dormant over long periods, only "awakening" when they sense moisture from infrequent rainfall. Now, a team led by researchers at Penn State—driven by projections that th

Newly discovered artifacts are evidence of the earliest known example of a tradition of making clay figurines in the Middle East—and challenge long-held beliefs about when and how clay began to be used for symbolic purposes in the region, according to a study published in PLOS On

The rate of sea-level rise is now more than 4 millimeters (0.16 inches) per year, having more than doubled since 1993–2002. Scientists estimate that this figure may go up to 10 millimeters (0.39 inches) per year in the near future. The inundation of coastlines and islands will af

Long before pottery became commonplace in Southwest Asia, people living beside the Upper Tigris were experimenting with ways to turn clay into containers.

Researchers at the Xinjiang Technical Institute of Physics and Chemistry (XTIPC) of the Chinese Academy of Sciences (CAS) have developed a core-shell confined iron-based single-atom catalyst that combines high Fenton-like catalytic activity with structural stability, enabling nea

Pictorial reading supports, such as icons, can help people with aphasia better comprehend the material and enjoy the reading process. But exactly what type of icon is most helpful?

Deep-sea mining could destroy unique habitats hidden inside metal-rich nodules and more — today's news signal.

Researchers at The University of Queensland are on a quest to identify key aroma compounds that could make no- and low-alcohol (NOLO) wine more attractive to drinkers.

Climate change has caused substantial alterations in forest ecosystems worldwide through changes in temperature and precipitation patterns. A new study from Osaka Metropolitan University (OMU) suggests that these effects are also evident in Japan, where forests are undergoing cha

Strangles is one of the most common infectious diseases of horses worldwide, but accurately determining whether a horse has been exposed to the bacterium that causes it can be challenging. Researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS)

Today, tropical waters typically host a wider range of marine animals than polar waters. This decline in marine biodiversity from the equator toward the North and South poles is known as the latitudinal diversity gradient.

Inside each cell is a dynamic world of molecules and chemicals, signals and receivers, and construction and destruction. With all this activity, it's inevitable that cellular parts get worn down over time. Thankfully, cells have evolved an efficient recycling process that breaks

Swiss researchers have found a new way of detecting the notorious date-rape drug GHB in urine for up to 72 hours after ingestion, in a possible boon to sexual assault investigations.

A European spacecraft has begun close inspections of an asteroid rammed by NASA four years ago in a planetary defense test.

The divisions over baboons run deep in Simon's Town, where their defenders and haters have clashed on social media and sometimes in real life for years.

Researchers at the Interface Science Department (ISC) have shown that electrochemical reactions at solid-solution interfaces can be impacted by two closely related, yet, distinct factors. The applied potential can drive a reaction forward. Additionally, electric fields in the ext

Earth's water may have been born in the planet's fiery atmosphere rather than delivered by icy comets or asteroids. Scientists discovered that rocky pebbles reacting with hydrogen under extreme heat can produce water in minutes, potentially generating hundreds of oceans' worth du

This summer, with its scarce rainfall and repeated heat waves, witnessed one of the most severe droughts in Europe since 1540. The resulting wildfires across western Europe received considerable media attention, but eastern Europe was also heavily hit, worsening the humanitarian
