Ukraine’s digital battle with Russia highlights the advantages of decentralized power

Ukraine’s digital battle with Russia highlights the advantages of decentralized power

Wired reports: When Russian president Vladimir Putin launched his full invasion of Ukraine in February, the world expected Moscow’s cyber and information operations to pummel the country alongside air strikes and shelling. Two months on, however, Kyiv has not only managed to keep the country online amidst a deluge of hacking attempts, but it has brought the fight back to Russia. Even Ukrainian officials are surprised by how ineffective Russia’s digital war has been. “I think that the root cause…

How democracies spy on their own citizens

How democracies spy on their own citizens

Ronan Farrow writes: Commercial spyware has grown into an industry estimated to be worth twelve billion dollars. It is largely unregulated and increasingly controversial. In recent years, investigations by the Citizen Lab and Amnesty International have revealed the presence of Pegasus on the phones of politicians, activists, and dissidents under repressive regimes. An analysis by Forensic Architecture, a research group at the University of London, has linked Pegasus to three hundred acts of physical violence. It has been used to…

DeepMind software that can predict the 3D shape of proteins is already changing biology

Nature reports: For more than a decade, molecular biologist Martin Beck and his colleagues have been trying to piece together one of the world’s hardest jigsaw puzzles: a detailed model of the largest molecular machine in human cells. This behemoth, called the nuclear pore complex, controls the flow of molecules in and out of the nucleus of the cell, where the genome sits. Hundreds of these complexes exist in every cell. Each is made up of more than 1,000 proteins…

The smaller bombs that could turn Ukraine into a nuclear war zone

The smaller bombs that could turn Ukraine into a nuclear war zone

The New York Times reports: In destructive power, the behemoths of the Cold War dwarfed the American atomic bomb that destroyed Hiroshima. Washington’s biggest test blast was 1,000 times as large. Moscow’s was 3,000 times. On both sides, the idea was to deter strikes with threats of vast retaliation — with mutual assured destruction, or MAD. The psychological bar was so high that nuclear strikes came to be seen as unthinkable. Today, both Russia and the United States have nuclear…

A large solar storm could knock out the power grid and the internet – an electrical engineer explains how

Typical amounts of solar particles hitting the earth’s magnetosphere can be beautiful, but too much could be catastrophic. Svein-Magne Tunli – tunliweb.no/Wikimedia, CC BY-NC-SA By David Wallace, Mississippi State University On Sept. 1 and 2, 1859, telegraph systems around the world failed catastrophically. The operators of the telegraphs reported receiving electrical shocks, telegraph paper catching fire, and being able to operate equipment with batteries disconnected. During the evenings, the aurora borealis, more commonly known as the northern lights, could be…

New cyber tool circumvents censorship sending texts to Russians about the war in Ukraine

New cyber tool circumvents censorship sending texts to Russians about the war in Ukraine

The Wall Street Journal reports: People around the world are using a new website to circumvent the Kremlin’s propaganda machine by sending individual messages about the war in Ukraine to random people in Russia. The website was developed by a group of Polish programmers who obtained some 20 million cellphone numbers and close to 140 million email addresses owned by Russian individuals and companies. The site randomly generates numbers and addresses from those databases and allows anyone anywhere in the…

The rise of Big Tech may just be starting

The rise of Big Tech may just be starting

Farhad Manjoo writes: The stock market has lately soured on the technology industry. Stock prices of many of the largest companies are down this year, some slightly — shares of Apple and Google have fallen more than 6 percent — and some stupendously: Facebook’s parent company, Meta, and Netflix have lost about a third of their value since the New Year. Because surging tech stocks drove a big part of the stock market’s rise in 2021, their decline has contributed…

The staggering ecological impacts of computation and the Cloud

The staggering ecological impacts of computation and the Cloud

Steven Gonzalez Monserrate writes: Screens brighten with the flow of words. Perhaps they are emails, hastily scrawled on smart devices, or emoji-laden messages exchanged between friends or families. On this same river of the digital, millions flock to binge their favorite television programming, to stream pornography, or enter the sprawling worlds of massively multiplayer online roleplaying games, or simply to look up the meaning of an obscure word or the location of the nearest COVID-19 testing center. Whatever your query,…

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

The Guardian reports: Humanity’s drugs have polluted rivers across the entire world and pose “a global threat to environmental and human health”, according to the most comprehensive study to date. Pharmaceuticals and other biologically active compounds used by humans are known to harm wildlife and antibiotics in the environment drive up the risk of resistance to the drugs, one of the greatest threats to humanity. The scientists measured the concentration of 61 active pharmaceutical ingredients (APIs) at more than 1,000…

Experiment demonstrates that nuclear fussion is no longer a pipedream solution for the climate crisis

Experiment demonstrates that nuclear fussion is no longer a pipedream solution for the climate crisis

CNN reports: There’s no silver bullet to the climate crisis, but nuclear fusion may be the closest thing to it. In the quest for a near-limitless, zero-carbon source of reliable power, scientists have generated fusion energy before, but they have struggled for decades to sustain it for very long. On Wednesday, however, scientists working in the United Kingdom announced that they more than doubled the previous record for generating and sustaining nuclear fusion, which is the same process that allows…

Applying machine learning to cosmology

Applying machine learning to cosmology

Charlie Wood writes: A group of scientists may have stumbled upon a radical new way to do cosmology. Cosmologists usually determine the composition of the universe by observing as much of it as possible. But these researchers have found that a machine learning algorithm can scrutinize a single simulated galaxy and predict the overall makeup of the digital universe in which it exists — a feat analogous to analyzing a random grain of sand under a microscope and working out…

I’m not sorry for my delay

Joe Pinsker writes: At first, being reachable all the time felt good. To professionals who started using BlackBerries 20 years ago to conduct business on the go, it registered as a superpower. “They felt like masters of the universe,” Melissa Mazmanian, an informatics professor at UC Irvine who studied the devices’ uptake in the early 2000s, told me. But as more people got mobile devices, responding to messages anytime became the norm among co-workers as well as friends and loved…

The worrisome rise of Non-Fungible Tokens

Caleb Scharf writes: Humans are very good at inventing commodities, and we’ve been at it for a long time. See that pebble over there? Well, that’s a better pebble than all these others, and if you give me something in exchange for it, I’ll let you take ownership. It’ll be your pebble, forever. And soon there will be a market in pebbles, a pebble community, pebble exhibitions and auctions filled with pebble speculators, pebble exchanges, and pebble artists. The deeper,…

Are we witnessing the dawn of post-theory science?

Laura Spinney writes: Isaac Newton apocryphally discovered his second law – the one about gravity – after an apple fell on his head. Much experimentation and data analysis later, he realised there was a fundamental relationship between force, mass and acceleration. He formulated a theory to describe that relationship – one that could be expressed as an equation, F=ma – and used it to predict the behaviour of objects other than apples. His predictions turned out to be right (if…

Waste is central, not peripheral, to everything we design, make and do

Waste is central, not peripheral, to everything we design, make and do

Justin McGuirk writes: The opposition between ‘nature’ and ‘culture’ is problematic for many reasons, but there’s one that we rarely discuss. The ‘nature vs culture’ dualism leaves out an entire domain that properly belongs to neither: the world of waste. The mountains of waste that we produce every year, the torrents of polluting effluent, the billions of tonnes of greenhouse gases, the new cosmos of microplastics expanding through our oceans – none of this has ever been entered into the…
