'Jumping genes' help stabilize DNA folding patterns
Remarkable Walking Sharks Are Strutting All Over and Here’s Their Deal
"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...
How the North Korean hackers behind WannaCry got away with a stunning crypto-heist
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
The so-called Lazarus group has used elaborate phishing schemes and cutting-edge money-laundering tools to steal money for Kim Jong-un’s regime.
Blue-emitting diode demonstrates limitations and promise of perovskite semiconductors
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
University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.
Going with the flow: New insights into mysterious fluid motions
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...
TV provider shifting satellite to high orbit over explosion fears
Water issuing from an ordinary faucet tells a complex tale of its journey through a pipe. At high velocities, the faucet's gushing stream is turbulent: chaotic, disorderly—like the crash of ocean waves.
Principles for a green chemistry future
US authorities said Friday they had granted permission to a TV provider to urgently lift a four-ton (3,600-kilogram) satellite to a so-called "graveyard orbit" over fears a battery fault may soon cause it to explode.
Shaping the social networks of neurons
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.
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...
