Phys.org / New synthesis strategy for (–)-gukulenin A reveals the chemistry behind its anticancer effects
A team of researchers from Yale University, U.S., successfully achieved the first stereoselective synthesis of the complex natural product (–)-gukulenin A (7), which exhibits notable cytotoxicity against ovarian cancer.
Phys.org / Ape ancestors and Neanderthals likely kissed, new analysis finds
A new study led by the University of Oxford has found evidence that kissing evolved in the common ancestor of humans and other large apes around 21 million years ago, and that Neanderthals likely engaged in kissing too. The ...
Phys.org / Humans are evolved for nature, not cities, say anthropologists
A new paper by evolutionary anthropologists Colin Shaw (University of Zurich) and Daniel Longman (Loughborough University) argues that modern life has outpaced human evolution. The study suggests that chronic stress and many ...
Phys.org / Archaeologists reveal second-largest Roman olive oil mill in the Roman Empire
Ca' Foscari University of Venice is co-directing a major international archaeological mission in the Kasserine region of Tunisia. The excavations, focused on the area of ancient Roman Cillium, on the border with present-day ...
Phys.org / How most of the universe's visible mass is generated: Experiments explore emergence of hadron mass
Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are much larger than the ...
Phys.org / Physicists drive antihydrogen breakthrough at CERN with record trapping technique
Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an innovative technique that increases the antihydrogen trapping rate by a factor of ten.
Phys.org / Disputed Jordan codices reveal age variations under ion-beam scrutiny
Scientists have delivered the most detailed assessment yet of a set of disputed lead books known as the Jordan codices. With debate centered on whether they could date back to the early Christian period, a study led by the ...
Phys.org / Social media use soars as kids drop sports, reading and the arts
In striking new statistics, experts warn of social media's growing grip on young people, with use among children and teens soaring by more than 200% since before COVID and showing no sign of decline.
Phys.org / Stars forge elements in new, uncharted ways: Experimental physicist discusses the 'i-process'
All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a nucleus heavier than iron ...
Phys.org / New cable design mitigates flaws in superconducting wires
When current flows through a wire, it doesn't always have a perfect path. Tiny defects within the wire mean current must travel a more circuitous route, a problem for engineers and manufacturers seeking reliable equipment.
Phys.org / Wine grape still carries molecular memory of its ancestry after 400 years, study finds
About 400 years ago, a cross between cabernet franc and sauvignon blanc gave birth to cabernet sauvignon. Today, cabernet sauvignon is the world's most-planted wine grape, dominating vineyards from Napa to Bordeaux. New research ...
Phys.org / Sharper MRI scans may be on horizon thanks to new physics-based model
Researchers at Rice University and Oak Ridge National Laboratory have unveiled a physics-based model of magnetic resonance relaxation that bridges molecular-scale dynamics with macroscopic magnetic resonance imaging (MRI) ...
