'Jumping genes' help stabilize DNA folding patterns

"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of Medicine in St. Louis indicates that such genes, also called transposable elements, play another, more surprising role: stabilizing the 3-D folding patterns of the DNA molecule...

Remarkable Walking Sharks Are Strutting All Over and Here’s Their Deal

Scientists have discovered four new species of walking sharks proving the ocean somehow can always seem a little more mysterious. According to a study published in the Marine and Freshwater Research journal on Tuesday, the Hemiscylliidae genus of sharks “walk” using their pectoral and pelvic fins to move across the ocean floor and live in coastal waters around northern Australia and...

We can’t trust the billionaires of Davos to solve a climate crisis they created | Payal Parekh

It’s time to turn away from the World Economic Forum and its mass-polluting ‘affiliates’. We need new, radical solutions• Payal Parekh is an international climate activistThis week, among the private chalets and deep snow of Davos, the world’s leading politicians and businesspeople have been spending their time at the World Economic Forum (WEF), and they’ve been talking about the...

A new twist on quantum communication in fiber

New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks. The team have demonstrated that multiple quantum patterns of twisted light can be transmitted across a conventional fiber link that, paradoxically, supports only...

Principles for a green chemistry future

In the most recent issue of the academic journal Science, the case is made for a future where the materials and chemicals that make up the basis of our society and our economy are healthful rather than toxic, renewable rather than depleting, and degradable rather than persistent.

Shaping the social networks of neurons

The three proteins teneurin, latrophilin and FLRT hold together and bring neighboring neurons into close contact, enabling the formation of synapses and the exchange of information between the cells. In the early phase of brain development, however, the interaction of the same proteins leads to the repulsion of migrating nerve cells, as researchers from the Max Planck Institute of Neurobiology and...
