The Associated Press files this report from Chernobyl, where invading tanks in February "churned up highly contaminated soil from the site of the 1986 accident that was the world's worst nuclear disaster..."

"Here in the dirt of one of the world's most radioactive places, Russian soldiers dug trenches. Ukrainian officials worry they were, in effect, digging their own graves." For more than a month, some Russian soldiers bunked in the earth within sight of the massive structure built to contain radiation from the damaged Chernobyl nuclear reactor. A close inspection of their trenches was impossible because even walking on the dirt is discouraged.... Maksym Shevchuck, the deputy head of the state agency managing the exclusion zone, believes hundreds or thousands of soldiers damaged their health, likely with little idea of the consequences, despite plant workers' warnings to their commanders. "Most of the soldiers were around 20 years old," he said....

The full extent of Russia's activities in the Chernobyl exclusion zone is still unknown, especially because the troops scattered mines that the Ukrainian military is still searching for. Some have detonated, further disturbing the radioactive ground. The Russians also set several forest fires, which have been put out.

Ukrainian authorities can't monitor radiation levels across the zone because Russian soldiers stole the main server for the system, severing the connection on March 2. The International Atomic Energy Agency said Saturday it still wasn't receiving remote data from its monitoring systems. The Russians even took Chernobyl staffers' personal radiation monitors....

When the Russians hurriedly departed March 31 as part of a withdrawal from the region that left behind scorched tanks and traumatized communities, they took more than 150 Ukrainian national guard members into Belarus. Shevchuck fears they're now in Russia. In their rush, the Russians gave nuclear plant managers a choice: Sign a document saying the soldiers had protected the site and there were no complaints, or be taken into Belarus. The managers signed.
The article includes more stories from Chernobyl's staff: Even now, weeks after the Russians left, "I need to calm down," the plant's main security engineer, Valerii Semenov, told The Associated Press. He worked 35 days straight, sleeping only three hours a night, rationing cigarettes and staying on even after the Russians allowed a shift change. "I was afraid they would install something and damage the system," he said in an interview....

Another Ukrainian nuclear plant, at Zaporizhzhia in southeastern Ukraine, remains under Russian control. It is the largest in Europe.
Long-time Slashdot reader MattSparkes also notes reports that researchers at Chernobyl "had been looking for bacteria to eat radioactive waste — but they now fear that their work was irreparably lost during the Russian invasion of the facility."

New Scientist reports (in a pay-walled article) that scientist Olena Pareniuk "was attempting to identify bacteria that could consume radioactive waste within Chernobyl's destroyed reactor before the Russian invasion. If her samples are lost it will likely be impossible to replace them."

"Everyone's favorite security focused operating system, OpenBSD 7.1 has been released for a number of architectures," writes long-time Slashdot reader ArchieBunker, "including Apple M1 chips."

Phoronix calls it "the newest version of this popular, security-minded BSD operating system." With OpenBSD 7.1, the Apple Silicon support is now considered "ready for general use" with keypad/touchpad support for M1 laptops, a power management controller driver added, I2C and SPI controller drivers, and a variety of other driver additions for supporting the Apple Silicon hardware.

OpenBSD 7.1 also has a number of other improvements benefiting the 64-bit ARM (ARM64) and RISC-V architectures. OpenBSD 7.1 also brings SMP kernel improvements, support for futexes with shared anonymous memory, and more. On the graphics front there is updating the Linux DRM code against the state found in Linux 5.15.26 as well as now enabling Intel Elkhart Lake / Jasper Lake / Rocket Lake support.
The Register notes OpenBSD now "supports a surprisingly wide range of hardware: x86-32, x86-64, ARM7, Arm64, DEC Alpha, HP PA-RISC, Hitachi SH4, Motorola 88000, MIPS64, SPARC64, RISC-V 64, and both Apple PowerPC and IBM POWER." The Register's FOSS desk ran up a copy in VirtualBox, and we were honestly surprised how quick and easy it was. By saying "yes" to everything, it automatically partitioned the VM's disk into a rather complex array of nine slices, installed the OS, a boot loader, an X server and display manager, plus the FVWM window manager. After a reboot, we got a graphical login screen and then a rather late-1980s Motif-style desktop with an xterm.

It was easy to install XFCE, which let us set the screen resolution and other modern niceties, and there are also KDE, GNOME, and other pretty front-ends, plus plenty of familiar tools such as Mozilla apps, LibreOffice and so on....

We were expecting to have to do a lot more work. Yes, OpenBSD is a niche OS, but the project gave the world OpenSSH, LibreSSL, the PF firewall as used in macOS, much of Android's Bionic C library, and more besides.... In a world of multi-gigabyte OSes, it's quite refreshing. It felt like stepping back into the early 1990s, the era of Real Unix, when you had to put in some real effort and learn stuff in order to bend the OS to your will — but in return, you got something relatively bulletproof.

On April 15th Americans filed their taxes with the Internal Revenue Service (or IRS). But on the same day ProPublica was reporting a difference between "the rich and the rest of us" — that their wealth just isn't easily defined: For one, wages make up only a small part of their earnings. And they have broad latitude in how they account for their businesses and investments. Their incomes aren't defined by a tax form. Instead, they represent the triumph of careful planning by skilled professionals who strive to deliver the most-advantageous-yet-still-plausible answers to their clients. For them, a tax return is an opening bid to the IRS. It's a kind of theory....

We counted at least 16 other billionaires (along with hundreds of other ultrawealthy people, including hedge fund managers and former CEOs) among the stimulus check recipients. This is just how our system works. It's why, in 2011, Jeff Bezos, then worth $18 billion, qualified for $4,000 in refundable child tax credits. (Bezos didn't respond to our questions.) A recent study by the Brookings Institution set out with a simple aim: to compare what owners of privately held businesses say they earn with the income that appears on the owners' tax returns. The findings were stark: "More than half of economic income generated by closely held businesses does not appear on tax returns and that ratio has declined significantly over the past 25 years."

That doesn't mean business owners are illegally hiding income from the IRS, though it's certainly a possible contributor. There are plenty of ways to make income vanish legally. Tax perks like depreciation allow owners to create tax losses even as they expand their businesses... "Losses" from one business can also be used to wipe out income from another. Sometimes spilling red ink can be lots of fun: For billionaires, owning sports teams and thoroughbred racehorses are exciting loss-makers. Congress larded the tax code with these sorts of provisions on the logic that what's good for businesses is good for the economy. Often, the evidence for this broader effect is thin or nonexistent, but you can be sure all this is great for business owners. The Brookings study found that households worth $10 million or more benefited the most from being able to make income disappear....

In the tax system we have, billionaires who'd really rather not pay income taxes can usually find a way not to. They can bank their accumulating gains tax-free and deploy tax losses to wipe out whatever taxable income they might have. They can even look forward to a few thousand dollars here and there from the government to help them raise their kids or get through a national emergency.
This system also means it's much harder to catch underreported income on the tax returns of the wealthy, the article points out. And with so many legal deducations, it's also hard to prove the low incomes really exceed what the law allows. Even then, the wealthy can still hire an army of the best tax lawyers to make their case in court.

And now thousands of auditors have left the agency — and have not been replaced. The end result? "Audits of the wealthy have plummeted.

"Business owners have still more reason to be bold...."

The New York Times reports: Images such as Ukrainian tractors towing away a disabled Russian tank and helicopter, although unverified, have not only helped fight Russian disinformation, but also helped support Ukrainian charities and even the Ukrainian military. The merchandise sales they have generated in the United States and elsewhere are surprising given that many people buying the T-shirts, stickers, coffee mugs and chocolate bars would never have thought about the Eastern European country before the conflict.
One example? Toronto-based Christian Borys, who decided to launch a site selling stickers of the Virgin Mary hoisting an antitank missile (adapted from a painting by the American artist Chris Shaw.) In eight weeks Borys' "Saint Javelin" site "has raised so far almost $1.5 million to assist the Ukrainian charity Help Us Help, which has branched into multiple services, and to provide protective equipment for journalists covering the war, he said." Mr. Borys, who had worked for the e-commerce platform Shopify before turning to journalism, said he created a website in half an hour, hoping to raise money to send to a charity for Ukrainian orphans. That night, he made 88 Canadian dollars in sales. By the time he added T-shirts at the end of February, the threat of war had turned into a full-scale invasion, and he said sales grew to 170,000 Canadian dollars a day — most coming from the United States. "The internet speaks in memes and it just became this crazy, viral sensation," he said. "I think it's because people were looking for a symbol of support, a way to support Ukraine, because they saw the whole injustice of everything...."

Three weeks ago, Mr. Borys, a Canadian of Ukrainian Polish origin, turned Saint Javelin from an all-volunteer effort to a full-time staff of four to keep up with demand. His website has branched out from the Virgin Mary to other saints: Saint Carl Gustaf wears a gas mask, while "Saint Olha, the Warrior Queen of Kyiv" wears a crown and hoists a bazooka over her camouflaged shoulders. "People on Instagram demand we make things basically," Mr. Borys said. "We get messages from people in Spain who say, 'Hey, we just shipped the C-90,' a shoulder-fired rocket propelled grenade launcher," he said. "And they'll say, 'Hey we want a saint for Spain' or a saint specific to that type of system."

"As more and more workers have fallen under the gaze of algorithms, a growing chorus of experts have noted how platform companies have paralleled the practices of colonial empires," writes MIT Technology review, "in using management tools to surveil and exploit a broad base of cheap labor." But resistance rose in Jakarta from an informal "base camp" for gig-worker drivers with Indonesia's largest ride-hailing company Gojek. And their experience "could reveal a new playbook for resistance: a way for workers to build collective power, achieve a measure of security, and take care of one another when seemingly no one else will."

"If one person shares a tip or a concern, it quickly travels through a loose network of WhatsApp and Telegram groups and across social media," the article points out — also noting that drivers eventually learned that by repeatedly rejecting certain gigs, they can train the app's algorithm to offer them different kinds of work. But that's just the beginning... Other drivers who are skilled in deciphering the mysteries of the algorithm offer paid "therapy services" to those who are struggling. A therapist will take over a client's phone for a week and slowly coax the account back to health before returning it to its owner.

Then there are more sophisticated hacks. The more tech-savvy in the driver communities have developed an entire ecosystem of unauthorized apps that help drivers tweak and tune their accounts, Qadri says. Some are relatively trivial, built simply to eliminate a reliance on Gojek's engineering team: they enlarge the text on the app's user interface to improve its readability, or help drivers accept jobs automatically, a feature Gojek has by now incorporated. But the most popular, with more than half a million downloads, spoof a phone's GPS. They can give the illusion that a driver who is resting is still working. This can avoid penalties for sick time or help quickly graduate an account to higher levels with more earning potential. Such apps can also give drivers access to places with high customer demand without requiring them to muscle into crowded spaces....

As driver networks have grown and accumulated political capital, they've also sought to agitate for broader reforms. They use social media to protest undesirable app updates or push for feature requests. Gojek now sends representatives to base camps to seek feedback and buy-in from drivers about forthcoming changes.
"This sense of community is now at the heart of what distinguishes Jakarta's drivers from other gig workers around the world," the article argues. "While such workers everywhere have felt increasingly squeezed and exploited by unforgiving algorithms, most have struggled to organize and effect concrete changes in the platforms that control their work or the government policies that enable their mistreatment."

Or, as one California law professor tells the site, "You don't get the kind of regulations you want without worker power, and you don't have worker power without worker community."

If you ranked all U.S. companies by annual revenue, Occidental Petroleum comes in at #183.

But Wednesday this massive "hydrocarbon exploration" company "outlined plans to advance its clean energy transition business," reports Reuters, "including spending between $800 million and $1 billion on a facility to remove carbon dioxide (CO2) from the air." The proposed facility, the world's largest direct air capture (DAC) project, is set to begin construction in the second half of this year in the Permian basin, the largest U.S. oilfield, with a start in 2024. The U.S. oil and gas producer is aiming to build a profitable business from providing services and technologies that pull CO2 out of the air and burying it underground to advance government and business climate mitigation goals. This year's investments in the low carbon business will total $275 million, and the company plans to develop over time three carbon sequestration hubs that will be online by 2025 and another 69 smaller DAC facilities by 2035, it told investors....

Occidental's first DAC facility has a goal of removing 1 million tonnes of CO2 from the atmosphere per year — 100 times bigger than all 19 DAC plants currently operating worldwide combined, according to the International Energy Agency.

"There's just not going to be enough other alternatives for CO2 offsets," said Occidental Chief Executive Vicki Hollub. "So this is a sure opportunity." Executives did not say when they expect the business to turn a profit. DAC is currently not commercial on a large scale. "We expect that to play out over the next five to 10 years as we develop plants," Richard Jackson, Occidental's head of U.S. onshore resources and carbon management operations, told Reuters by phone. "The commerciality of those plants will be determined by mainly the market".
Last month Occidental announced that Airbus had already pre-purchased "400,000 tonnes of carbon removal credits from [Occidental's] planned first Direct Air Capture facility," specifically, "the capture and permanent sequestration of 100,000 tonnes of CO2 from the atmosphere each year for four years — with an option to secure more volume in the future."

Occidental called the deal "indicative of the availability of a feasible, affordable, and scalable decarbonization solution for aviation and other hard-to-abate industries."

After startup Axiom Space brokered the first visit to the Space Station by an all-private crew, the AX-1 mission turned into a "longer-than-expected" stay, reports CNN. It launched on April 8 and "was originally billed as a 10-day mission," CNN notes, "but delays have extended the mission by about a week." The four crew members — Michael López-Alegría, a former NASA astronaut-turned-Axiom employee who is commanding the mission; Israeli businessman Eytan Stibbe; Canadian investor Mark Pathy; and Ohio-based real estate magnate Larry Connor — are slated to leave the space station aboard their SpaceX Crew Dragon capsule on Sunday at 8:55 pm ET. That's another 24-hour delay from what NASA and Axiom were targeting on Saturday. They now plan to spend a day free flying through orbit before plummeting back into the atmosphere and parachuting to a splashdown landing off the coast of Florida at about 1 pm ET Monday, according to a tweet from Kathy Lueders, the head of NASA's human spaceflight program...

During their first 12 days on the space station, the group stuck to a regimented schedule, which included about 14 hours per day of activities, including scientific research that was designed by various research hospitals, universities, tech companies and more. They also spent time doing outreach events by video conferencing with children and students. The weather delays then afforded to them "a bit more time to absorb the remarkable views of the blue planet and review the vast amount of work that was successfully completed during the mission," according to Axiom....

It's not the first time paying customers or otherwise non-astronauts have visited the ISS, as Russia has sold seats on its Soyuz spacecraft to various wealthy thrill seekers in years past. But AX-1 is the first mission with a crew entirely comprised of private citizens with no active members of a government astronaut corps accompanying them in the capsule during the trip to and from the ISS. It's also the first time private citizens have traveled to the ISS on a US-made spacecraft.

Dirk Hohndel gets frequently mentioned on Slashdot. He was a very early contributor to Linux (and for the last five years the chief open source officer and vice president at VMware). But he's also the guy who interviews Linus Torvalds in the keynote sessions of Open Source Summits.

Hohndel "has a well known track record with Linux going back to the 1990's," reports Phoronix, and was even a member of the Linux Foundation Board of Directors.

But they add that now Hohndel has "somewhat surprisingly has moved on to promoting a blockchain effort."

Dirk Hohndel was CTO at SUSE going back to the mid-90's before joining Intel for a fifteen year run that ended in 2016 where he was Intel's Chief Linux and Open-Source Technologist...

When Dirk left VMware unexpectedly at the beginning of the year, he wrote on LinkedIn that he felt he completed his job at the company in driving open-source transformation. He was leaving to go "look for the next opportunity, the next step in my career" and now it apparently is with blockchain. The surprising news today is that he's joined the Cardano Foundation. The Cardano Foundation is a Swiss-based foundation built around the Cardano public blockchain platform. Cardano is open-source and is the most notable proof-of-stake blockchain that was started by Ethereum co-founder Charles Hoskinson. Cardano has its own cryptocurrency, ADA....

Dirk will be serving as the Cardano Foundation's Chief Open-Source Officer.
Interestingly, Linus Torvalds appears to be less enthralled with blockchain technologies. Last year ZDNet reported on the reaction when Linux Foundation executive director Jim Zemlin suggested Torvalds sell an NFT of the 1991 email that first announced Linux to the world.

"An amused and appalled Torvalds replied, "I'm staying out of the whole craziness with crypto and NFTs. Those people are cuckoo!"

Writing for the New Yorker, Ronan Farrow reports on Pegasus, "a spyware technology designed by NSO Group, an Israeli firm, which can extract the contents of a phone, giving access to its texts and photographs, or activate its camera and microphone to provide real-time surveillance — exposing, say, confidential meetings." Pegasus is useful for law enforcement seeking criminals, or for authoritarians looking to quash dissent.... In Catalonia, more than sixty phones — owned by Catalan politicians, lawyers, and activists in Spain and across Europe — have been targeted using Pegasus. This is the largest forensically documented cluster of such attacks and infections on record. Among the victims are three members of the European Parliament... Catalan politicians believe that the likely perpetrators of the hacking campaign are Spanish officials, and the Citizen Lab's analysis suggests that the Spanish government has used Pegasus....

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 target members of Rwanda's opposition party and journalists exposing corruption in El Salvador. In Mexico, it appeared on the phones of several people close to the reporter Javier Valdez Cárdenas, who was murdered after investigating drug cartels. Around the time that Prince Mohammed bin Salman of Saudi Arabia approved the murder of the journalist Jamal Khashoggi, a longtime critic, Pegasus was allegedly used to monitor phones belonging to Khashoggi's associates, possibly facilitating the killing, in 2018. (Bin Salman has denied involvement, and NSO said, in a statement, "Our technology was not associated in any way with the heinous murder.") Further reporting through a collaboration of news outlets known as the Pegasus Project has reinforced the links between NSO Group and anti-democratic states.

But there is evidence that Pegasus is being used in at least forty-five countries, and it and similar tools have been purchased by law-enforcement agencies in the United States and across Europe. Cristin Flynn Goodwin, a Microsoft executive who has led the company's efforts to fight spyware, told me, "The big, dirty secret is that governments are buying this stuff — not just authoritarian governments but all types of governments...." "Almost all governments in Europe are using our tools," Shalev Hulio, NSO Group's C.E.O., told me. A former senior Israeli intelligence official added, "NSO has a monopoly in Europe." German, Polish, and Hungarian authorities have admitted to using Pegasus. Belgian law enforcement uses it, too, though it won't admit it.
Calling the spyware industry "largely unregulated and increasingly controversial," the article notes how it's now impacting major western democracies. "The Citizen Lab's researchers concluded that, on July 26 and 27, 2020, Pegasus was used to infect a device connected to the network at 10 Downing Street, the office of Boris Johnson, the Prime Minister of the United Kingdom.... The United States has been both a consumer and a victim of this techÂnology. Although the National Security Agency and the C.I.A. have their own surveillance technology, other government offices, including in the military and in the Department of Justice, have bought spyware from private companies, according to people involved in those transactions."

But are the company's fortunes faltering? The company has been valued at more than a billion dollars. But now it is contending with debt, battling an array of corporate backers, and, according to industry observers, faltering in its long-standing efforts to sell its products to U.S. law enforcement, in part through an American branch, Westbridge Technologies. It also faces numerous lawsuits in many countries, brought by Meta (formerly Facebook), by Apple, and by individuals who have been hacked by NSO....

In November, the [U.S.] Commerce Department added NSO Group, along with several other spyware makers, to a list of entities blocked from purchasing technology from American companies without a license. I was with Hulio in New York the next day. NSO could no longer legally buy Windows operating systems, iPhones, Amazon cloud servers — the kinds of products it uses to run its business and build its spyware.

The U.S. government "is launching a $6 billion effort to rescue nuclear power plants at risk of closing," reports the Associated Press, "citing the need to continue nuclear energy as a carbon-free source of power that helps to combat climate change." A certification and bidding process opened Tuesday for a civil nuclear credit program that is intended to bail out financially distressed owners or operators of nuclear power reactors, the U.S. Department of Energy told The Associated Press exclusively, shortly before the official announcement. It's the largest federal investment in saving financially distressed nuclear reactors... "U.S. nuclear power plants contribute more than half of our carbon-free electricity, and President Biden is committed to keeping these plants active to reach our clean energy goals," Energy Secretary Jennifer Granholm said in a statement. "We're using every tool available to get this country powered by clean energy by 2035, and that includes prioritizing our existing nuclear fleet to allow for continued emissions-free electricity generation and economic stability for the communities leading this important work...."

A dozen U.S. commercial nuclear power reactors have closed in the past decade before their licenses expired, largely due to competition from cheaper natural gas, massive operating losses due to low electricity prices and escalating costs, or the cost of major repairs. This has led to a rise in emissions in those regions, poorer air quality and the loss of thousands of high-paying jobs, dealing an economic blow to local communities, according to the Department of Energy. A quarter or more of the fleet is at risk, the Department of Energy added. The owners of seven currently operating reactors have already announced plans to retire them through 2025.... Twenty more reactors faced closure in the last decade before states stepped in to save them, according to the Nuclear Energy Institute , the industry's trade association.... Low electricity prices are the main cause of this trend, though federal and state policies to boost wind and solar have contributed as well, the NEI added.

There are 55 commercial nuclear power plants with 93 nuclear reactors in 28 U.S. states. Nuclear power already provides about 20% of electricity in the U.S., or about half the nation's carbon-free energy. If reactors do close before their licenses expire, fossil fuel plants will likely fill the void and emissions will increase, which would be a substantial setback, said Andrew Griffith, acting assistant secretary for nuclear energy at DOE. While natural gas may be cheaper, nuclear power hasn't been given credit for its carbon-free contribution to the grid and that has caused nuclear plants to struggle financially, Griffith added....

David Schlissel, at the Ohio-based Institute for Energy Economics and Financial Analysis, said he wishes the federal government, before it allocated the $6 billion, had analyzed whether that money might have been better spent on ramping up renewables, battery storage and energy efficiency projects, which can be done quickly and cheaply to displace fossil fuels.

The Energy Department has teamed with GM and MathWorks to launch an EcoCAR Electric Vehicle Challenge that asks student groups at 15 North American universities to develop more efficient EV technology. From a report: The will have students tinker with a Cadillac Lyriq over four years as they develop automation, connectivity and propulsion tech, and they can will win annual prizes based on their progress. The teams are also expected to use a mix of connected car and sensor tech to enable sharing EV battery power with homes, "recreational uses" (think camping) and the electrical grid. GM is supplying the cars as part of a broader $6 million investment in the challenge. EcoCAR kicks off this fall.

European Union lawmakers have secured a provisional deal on a landmark update to rules for digital services operating in the region -- grabbing political agreement after a final late night/early morning of compromise talks on the detail of what is a major retooling of the bloc's existing ecommerce rulebook. From a report: The political agreement on the Digital Services Act (DSA) paves the way for formal adoption in the coming weeks and the legislation entering into force -- likely later this year. Although the rules won't start to apply until 15 months after that -- so thereâ(TM)s a fairly long lead in time to allow companies to adapt.

The regulation is wide ranging -- setting out to harmonize content moderation and other governance rules to speed up the removal of illegal content and products. It addresses a grab-bag of consumer protection and privacy concerns, as well as introducing algorithmic accountability requirements for large platforms to dial up societal accountability around their services. While 'KYC' requirements are intended to do the same for online marketplaces.

The Covid-19 pandemic brought on a surge of "zoom-bombing" as hackers and pranksters crashed into virtual meetings with abusive messages and imagery. Now, Zoom has agreed to a "historic" payout of $85m as part of a class-action settlement brought by its users, including church groups who said they were left traumatized by the disruptions. From a report: As part of the settlement agreement, Zoom Video Communications, the company behind the teleconference application that grew popular during the pandemic, will pay the $85m to users in cash compensation and also implement reforms to its business practices. On Thursday, federal judge Laurel Beeler of California granted final approval to the agreement which was first filed in July. The agreement was granted preliminary approval in October. The settlement stems from 14 class-action complaints filed against the San Jose-based company by users between March and May of 2020, in which they argued that the company violated their privacy and security.

Analysis of thousands of tumours has unveiled a treasure trove of clues about the causes of cancer, representing a significant step towards the personalisation of treatment. The Guardian: Researchers say that for the first time it is possible to detect patterns -- called mutational signatures -- in the DNA of cancers. These provide clues including about whether a patient has had past exposure to environmental causes of cancer such as smoking or UV light, for example. This is important as these signatures allow doctors to look at each patient's tumour and match it to specific treatments and medications. However, these patterns can be detected only through analysis of the vast amounts of data unearthed by whole genome sequencing -- identifying the genetic makeup of a cell.
