Road testing: Research team studies potholes in quest for better asphalt sustainability

A Missouri S&T research team is studying asphalt binders, the materials that hold road materials together, to better understand how they perform and help improve the durability of Missouri's roads. Because roads are constantly exposed to sunlight, changing weather and the stress of daily traffic, these binders can break down over time, making reliable testing essential.

'Listen, father!': 1,700-year-old tomb discovered in Egypt contains a poem in ancient Greek and spells to protect the dead

Archaeologists in Egypt have discovered a 1,700-year-old limestone tomb with a rare poem inscribed on it in ancient Greek, likely from a son lamenting his father's death. The tomb, which has a pyramid-shaped roof, dates to the fourth century, when the Roman Empire controlled Egypt. A team found it in the Dakhla Oasis, near ancient Mothis (modern-day Mut), a prominent city in the oasis. Built for a husband and wife, the tomb has a stone plaque containing a 19-line poem written in ancient Greek, representatives of the Egyptian Ministry of Tourism and Antiquities said in a translated statement. The deceased man was named Pisechtes and may have been a judge. However, the statement didn't mention...

The Andes were supposed to stop this cacao killer. They didn't.

Black pod disease destroys up to a quarter of the world's cacao every year, roughly 700,000 metric tons worth more than $2 billion. The water mold responsible across the Americas is Phytophthora palmivora, and in Colombia it is the dominant Phytophthora on cacao. How it travels among the country's three Andean regions, though, has remained an open question.

How to balance quantum batteries' high power with stable energy delivery

Quantum batteries are an emerging area of research, with progress coming from theoretical studies and proof-of-principle experiments in small quantum systems. Unlike conventional chemical batteries used in everyday life, they use quantum systems to store and transfer energy. Researchers are exploring them as potential future energy sources for quantum processors and other quantum technologies.

Shared DNA switch turns on genes in both bacteria and yeast

Microbial cell factories that produce pharmaceutical ingredients and other useful compounds include both the bacterium Escherichia coli and yeast, the organism used to leaven bread and ferment alcohol. The two organisms turn genes on by different rules, so a production design built for one has been hard to transfer to the other.

Childless women who shape history and culture are still judged on not being mothers

Childless women who shape history and culture are still judged on not being mothers

The women I return to most—Elizabeth I, her potential heir Arbella Stuart (and rival to James Charles Stuart, later King James I), Virginia Woolf, Katharine Hepburn, Debbie Harry—never had children. Their reasons were wildly different: some chose not to, some were prevented, and some never got the chance. The pattern raises two questions. Did their work or their position cost them their choice? And why does it seem to matter, overshadowing the legacies and achievements of great women?

SpaceX's Starship reaches orbit for the first time, then returns early and explodes

Starship has made it to orbit for the first time ever. But the loss of an engine during its nail-biting ascent meant SpaceX's mission ended earlier than planned — with an explosion to boot. The tallest and most powerful rocket ever built blasted off from SpaceX's Starbase in Boca Chica, Texas on Monday (Sept. 28) at 8.49 a.m. ET (7.49 a.m. local time). Soon after launch, one of Starship's six main upper-stage Raptor engines failed after separating from the lower-stage booster rocket. A tense few minutes followed while the mission team deliberated over whether the mission should continue to orbit. Eventually, the call came through: "Go for orbit." Liftoff of Starship! https://t.co/40D8bXSkr2S...

Laser temporarily reprograms ultrathin optical device without electrodes

A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and telecommunications. Most devices are built to perform a particular job. If you want them to do something different, you generally need to replace a component, rewire the system or manufacture a new one. For example, every time you ask a large language model like ChatGPT or Claude a question, many electrical signals race through computer chips, carrying information and performing calculations. This takes energy, and lots of it.
