The Truth About Vikings Is More Complicated Than Museums Admit

Scandinavian museums use Viking history to negotiate the tension between popular myths, archaeological evidence, and modern national identity. Walk into a major museum in Scandinavia, and there is a good chance you will encounter an exhibition devoted to the Vikings. Visitors have no shortage of options. In Copenhagen, Denmark’s capital, the National History Museum maintains […]

Chromosome Chaos Reveals 81 New Cancer-Causing Genes

Testing thousands of genes in living tumors revealed hidden drivers of aggressive basal-like breast cancer that cell cultures largely failed to detect. Inside basal-like breast cancer cells, entire stretches of chromosomes may disappear while others are copied repeatedly. Each altered region can contain hundreds of genes, leaving researchers with a difficult question: which of those […]

Rare Autism-Linked Syndrome Is Far More Common Than Scientists Thought

A large genetic analysis suggests that Phelan-McDermid syndrome may affect far more people than previously recognized. For some families, a genetic diagnosis can explain years of medical, developmental, and behavioral challenges. But many people with Phelan-McDermid syndrome (PMS) may still have no idea that they carry the condition. Researchers led by the Seaver Autism Center […]

New Catalyst Turns Stubborn Plant Waste Into Valuable Chemicals

Atomic insight could make plant waste a more practical source of fuels, plastics and chemicals. Every year, agriculture and forestry leave behind large amounts of plant material containing lignin, the substance that helps stems, wood, and other tissues remain rigid. Lignin can make up (up to 35%) of this discarded biomass and represents nature’s largest […]

Quantum Gravity May Be Far Less Quantum Than Physicists Expected

A new study reveals that some proposed signatures of quantum gravity may have an unexpected classical explanation. Imagine placing an object in two locations at once. Quantum mechanics allows such a possibility, at least for sufficiently small systems. But if the object occupies multiple positions, what happens to the gravity surrounding it? That question lies […]

Scientists Discover Why Teenage Memories Can Become Temporarily Inaccessible

Some memories from adolescence may not disappear. The brain may simply lock them away for a time while its memory system is being rebuilt. A study in mice has uncovered an unexpected wave of remodeling in a brain region that helps preserve and retrieve long-term memories. During late adolescence, the protective structures surrounding key neurons […]
