Deadly cyclone Freddy has become Earth’s longest-lived tropical storm

Posted by in categories: climatology, sustainability

Remarkably, the storm has rapidly intensified six times.

Rapid intensification describes an uptick in winds of 35 mph or greater in 24 hours. Research has shown rapid intensification increasing in frequency in many ocean basins because of rising ocean temperatures linked to human-caused climate change.

Asteroid discovery suggests ingredients for life on Earth came from space

Posted by in categories: biological, chemistry, space

March 21 (Reuters) — Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago.

Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency’s Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.

The Ryugu samples, which looked like dark-gray rubble, were transported 155 million miles (250 million km) back to Earth and returned to our planet’s surface in a sealed capsule that landed in 2020 in Australia’s remote outback for analysis in Japan.

Scientists Make Quantum Light Breakthrough: ‘This Experiment Is Beautiful’

Posted by in categories: innovation, quantum physics

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, published in the journal Nature Physics on March 20, describes how the researchers were able to make two photons of light interact and measure the difference between these interacting photons and a single photon.

New treatment could see humans start to live to 150 within the next decade

Posted by in category: biotech/medical

A treatment that enables human beings to live to the age of 150 could be available within the next five to 10 years, one of the world’s most eminent plastic surgeons has claimed. Dr Steven Cohen, who specialises in complex aesthetic facial and regenerative surgery, believes the results of studies and advances in the medical sphere could soon pave the way to extend our lives.

Dissipative Pairing Interactions: Quantum Instabilities, Topological Light, and Volume-Law Entanglement

Posted by in categories: law, quantum physics

A new class of dynamical instabilities generated by a stable photonic lattice Hamiltonian and stable dissipative pairing interaction is sensitive to wavefunction localization and allows selective excitation and entanglement of pure topological photonic edge states with minimal resources.

Gene therapy: Everything you need to know about the DNA-tweaking treatments

Posted by in categories: biotech/medical, genetics

Gene therapy has been headline news in recent years, in part due to the rapid development of biotechnology that enables doctors to administer such treatments. Broadly, gene therapies are techniques used to treat or prevent disease by tweaking the content or expression of cells’ DNA, often by replacing faulty genes with functional ones.

The term “gene therapy” sometimes appears alongside misinformation about mRNA vaccines, which include the Pfizer and Moderna COVID-19 vaccines. These vaccines contain mRNA, a genetic cousin of DNA, that prompts cells to make the coronavirus “spike protein.” The vaccines don’t alter cells’ DNA, and after making the spike, cells break down most of the mRNA. Other COVID-19 shots include the viral vector vaccines made by AstraZeneca and Johnson & Johnson, which deliver DNA into cells to make them build spike proteins. The cells that make spike proteins, using instructions from either mRNA or viral vector vaccines, serve as target practice for the immune system, so they don’t stick around long. That’s very, very different from gene therapy, which aims to change cells’ function for the long-term.
