New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from every measurement. Their experiment outperforms even a perfect, noise-free run of the old method. The work appeared in Physical Review Letters.
Flinders University researchers examined AOD VET provision in Australia in 2024, comparing it with a 2011 review, and found there has been a contraction in programs despite a major increase in the share of private providers—while demand for qualified support workers continues to increase.
When people think about climate change and animals, they might picture melting sea ice, drought-stricken landscapes or species struggling in the wild. Far less attention is given to the animals living in our care. Yet as heat waves become more frequent, intense and unpredictable, zoos may be facing one of the biggest animal welfare challenges of the coming decades.
Children and seniors who have difficulty chewing and swallowing conventional tablets may have an easier way to find pain relief. Cornell researchers have developed an ultrafast-dissolving nanofiber film that can deliver a cocktail of three drugs so quickly and effectively that 90% of the formulation is released in less than two seconds.
A new review led by professor Emese Bordy at the University of Cape Town (UCT) Department of Geological Sciences brings together more than two decades of research on the Karoo Supergroup, revealing how scientific understanding of this iconic geological archive has changed since 2000.
Cells travel through the body both individually and in collective groups during development, wound healing and diseases such as cancer. New research from the McKelvey School of Engineering at Washington University in St. Louis shows that cells can sense even the smallest defects, or micro-injuries, in the surface beneath which they travel and stall long enough to begin the healing process.
The appeal of soccer matches to spectators is a key factor in the success of professional sports leagues. League officials therefore seek to make competitions as interesting as possible. But how can the appeal of matches and competitions be measured?
Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year. Caused by the bacterium Borrelia burgdorferi, it is most often spread by bites from blacklegged ticks. Lyme can be treated with antibiotics, but if untreated, infection can spread to the joints, heart and nervous system, and some people can experience persistent symptoms.
A 4,000-year-old painted stone plaque discovered on a remote Indonesian island is the first known example of portable art belonging to the Austronesian Painting Tradition (APT), providing a rare glimpse into the symbolic world of some of history's greatest maritime voyagers.
