A German-American research team has discovered two highly unusual bacterial species in the tissue of two deep-sea corals from the Gulf of Mexico. These previously unknown coral symbionts have an extremely reduced genome and lack the ability to obtain energy from carbohydrates, the team reports in an article published in the journal Nature Communications.

As the Earth faces unprecedented climate change, a look into the planet's deep past may provide vital insights into what may lie ahead. Knowledge of the natural world millions of years ago is fragmented, but a 15-year study of a site in Bolivia by an international team led by Case Western Reserve University provides a comprehensive view of an ancient ecosystem when the Earth was much warmer than today.

Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano, a seismic wave was recorded by two distant seismic stations. Now, researchers argue that similar early signals could be used to warn of other impending eruptions in remote oceanic volcanoes.

Fine tuning an experimental setup improved a detector's sensitivity to neutrinos and perhaps eventually dark matter—two difficult-to-measure forms of matter which hold great importance for understanding particle physics and experimental cosmology. The University-of-Michigan-led study is published in Physical Review D.

Researchers from the UCLA Samueli School of Engineering and the University of Rome Tor Vergata in Italy have developed synthetic genes that function like the genes in living cells.

A new study highlights key challenges and tensions in research ethics, particularly in light of emerging technologies such as artificial intelligence, and calls for the adoption of new research ethics policies.

In 2022, archaeologists from the Nicolaus Copernicus University in Toruń made a startling discovery in Pień, near Dąbrowa Chełmińska, Poland: the grave of a young woman buried with a sickle around her neck and a triangular padlock on her toe. This peculiar arrangement quickly earned her the moniker of the "Vampire Woman." The burial, likely from the 17th century, featured anti-vampire elements—meant, according to some interpretations, to prevent the dead from rising. Now, a collaboration between scientists and Swedish sculptor and archaeologist Oscar Nilsson has brought her face back to life through meticulous reconstruction, reports Nicolaus Copernicus University in Toruń. Using a combination of 3D printing, DNA analysis, and forensic artistry, Nilsson recreated the visage of this enigmatic woman, whose life and death remain a topic of fascination and speculation. 17th Century Sickle Burials Reflect Belief that Demons Stalked War-Torn Poland Rh-Negative Blood: An Exotic Bloodline or Random Mutation?

The Supreme Court agreed on Monday to hear a bid by Louisiana officials and civil rights groups to preserve an electoral map that raised the number of Black-majority congressional districts in a legal challenge by a group of voters who called themselves "non-African American."

Former President Donald Trump referenced the recent killing of a Georgia woman by repeating his call for the death penalty when an illegal migrant is found guilty of murder. The man accused of killing 25-year-old Minelys "Mimi" Rodriguez-Ramirez last week is said to be...
