Moving quickly and carefully in two layers of gloves, Florian Krauss sets a cube of ice into a gold-plated cylinder that glows red in the light of the aiming laser. He steps back to admire the machine, covered with wires and gauges, that turns polar ice into climate data.

If this were a real slice of precious million-year-old ice from Antarctica and not just a test cube, he’d next seal the extraction vessel under a vacuum and power on the 150-megawatt main laser, slowly causing the entire ice sample to sublimate directly into gas. For Krauss, a PhD student at the University of Bern in Switzerland, this would unlock its secrets, exposing the concentrations of greenhouse gases like carbon dioxide trapped within.

To better understand the role atmospheric carbon dioxide plays in Earth’s climate cycles, scientists have long turned to ice cores drilled in Antarctica, where snow layers accumulate and compact over hundreds of thousands of years, trapping samples of ancient air in a lattice of bubbles that serve as tiny time capsules. By analyzing those bubbles and the ice’s other contents, like dust and water isotopes, scientists can connect greenhouse-gas concentrations with temperatures going back 800,000 years.

Europe’s Beyond EPICA (European Project for Ice Coring in Antarctica) initiative, now in its third year, hopes to eventually retrieve the oldest core yet, dating back 1.5 million years. This would extend the climate record all the way back to the Mid-Pleistocene Transition, a mysterious period that marked a major change in the frequency of Earth’s climatic oscillations—cycles of repeating glacial and warm periods.

Successfully drilling a core that old—a years-long endeavor—might be the easy part. Next, scientists must painstakingly free the trapped air from that ice. Krauss and his colleagues are developing an innovative new way to do that.

“We’re not interested in the ice itself—we’re just interested in the air samples included, so we needed to find a new way to extract the air from the ice,” he says.

Melting isn’t an option because carbon dioxide easily dissolves into water. Traditionally, scientists have used mechanical extraction methods, grinding up samples of individual layers of ice to free the air. But grinding wouldn’t be effective for the Beyond EPICA ice in the university’s storage freezer, which is kept at 50 °C below zero. The oldest ice at the very bottom of the core will be so compressed, and the individual annual layers so thin, that bubbles won’t be visible—they’ll have been pressed into the lattice of ice crystals, forming a new phase called clathrate.

“At the very bottom, we expect 20,000 years of climate history compressed in only one meter of ice,” says Hubertus Fischer, head of the past climate and ice core science group at Bern. That’s a hundredth the thickness of any existing ice core record.

The new method Krauss and Fischer are developing is called deepSLice. (A pizza menu is taped to the side of the device right under the laser warning labels, a gift from a pizzeria in Australia with the same name.) DeepSLice has two parts. The Laser-Induced Sublimation Extraction Device, or LISE, fills half a room in the team’s lab space. LISE aims a near-infrared laser continuously at a 10-centimeter slice of ice core so that it turns directly from solid to gas under extremely low pressure and temperature. The sublimated gas then freezes into six metal dip tubes cooled to 15 K (-258 °C), each containing the air from one centimeter of ice core. Finally the samples are loaded into a custom-made absorption spectrometer based on quantum cascade laser technology, which shoots photons through the gas sample to measure concentrations of carbon dioxide, methane, and nitrous oxide simultaneously. Another big advantage of this system is that it takes a lot less ice (and work) than the old method of analysis, in which scientists measured methane by melting ice (it doesn’t dissolve into water) and measured carbon dioxide by grinding ice.

DeepSLice offers “a unique capability that nobody else has,” says Christo Buizert,

Finding value in generative AI for financial services

UBS report cover

With tools such as ChatGPT, DALLE-2, and CodeStarter, generative AI has captured the public imagination in 2023. Unlike past technologies that have come and gone—think metaverse—this latest one looks set to stay. OpenAI’s chatbot, ChatGPT, is perhaps the best-known generative AI tool. It reached 100 million monthly active users in just two months after launch, surpassing even TikTok and Instagram in adoption speed, becoming the fastest-growing consumer application in history.

UBS report cover 1

According to a McKinsey report, generative AI could add $2.6 trillion to $4.4 trillion annually in value to the global economy. The banking industry was highlighted as among sectors that could see the biggest impact (as a percentage of their revenues) from generative AI. The technology “could deliver value equal to an additional $200 billion to $340 billion annually if the use cases were fully implemented,” says the report.

For businesses from every sector, the current challenge is to separate the hype that accompanies any new technology from the real and lasting value it may bring. This is a pressing issue for firms in financial services. The industry’s already extensive—and growing—use of digital tools makes it particularly likely to be affected by technology advances. This MIT Technology Review Insights report examines the early impact of generative AI within the financial sector, where it is starting to be applied, and the barriers that need to be overcome in the long run for its successful deployment.

DOWNLOAD THE REPORT

The main findings of this report are as follows:

Corporate deployment of generative AI in financial services is still largely nascent. The most active use cases revolve around cutting costs by freeing employees from low-value, repetitive work. Companies have begun deploying generative AI tools to automate time-consuming, tedious jobs, which previously required humans to assess unstructured information.

There is extensive experimentation on potentially more disruptive tools, but signs of commercial deployment remain rare. Academics and banks are examining how generative AI could help in impactful areas including asset selection, improved simulations, and better understanding of asset correlation and tail risk—the probability that the asset performs far below or far above its average past performance. So far, however, a range of practical and regulatory challenges are impeding their commercial use.Legacy technology and talent shortages may slow adoption of generative AI tools, but only temporarily. Many financial services companies, especially large banks and insurers, still have substantial, aging information technology and data structures, potentially unfit for the use of modern applications. In recent years, however, the problem has eased with widespread digitalization and may continue to do so. As is the case with any new technology, talent with expertise specifically in generative AI is in short supply across the economy. For now, financial services companies appear to be training staff rather than bidding to recruit from a sparse specialist pool. That said, the difficulty in finding AI talent is already starting to ebb, a process that would mirror those seen with the rise of cloud and other new technologies.

More difficult to overcome may be weaknesses in the technology

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Unpacking the hype around OpenAI’s rumored new Q* model

Ever since last week’s dramatic events at OpenAI, the rumor mill has been in overdrive about why the company’s board tried to oust CEO Sam Altman.

While we still don’t know all the details, there have been reports that researchers at OpenAI had made a “breakthrough” in AI that alarmed staff members. The claim is that they came up with a new way to make powerful AI systems and had created a new model, called Q* (pronounced Q star), that was able to perform grade-school level math.

Some at OpenAI reportedly believe this could be a breakthrough in the company’s quest to build artificial general intelligence, a much-hyped concept of an AI system that is smarter than humans.

So what’s actually going on? And why is grade-school math such a big deal? Our senior AI reporter Melissa Heikkilä called some experts to find out how big of a deal any such breakthrough would really be. Here’s what they had to say.

The Download: OpenAI’s wild year, and tech’s cult of personality

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Inside OpenAI’s wild year

Few companies can say they’ve had more of a rollercoaster year than OpenAI. At the beginning of 2023, the world’s hottest AI startup was riding high on the success of its ChatGPT chatbot. Now, it’s dusting itself off from an attempted coup which saw Sam Altman ousted and reinstated as the company’s CEO within a few short days.

Our AI experts have been following OpenAI’s every move throughout the year, often with exclusive access to the people building the revolutionary products and systems. Check out just some of the highlights from the past year—and what we think is coming next.

+ ChatGPT is everywhere. Here’s where it came from. While ChatGPT may have looked like an overnight sensation, it was actually built on decades of research.

+ Back in April, our senior AI editor Will Douglas Heaven had exclusive conversations with four OpenAI insiders to learn more about how they built the viral chatbot.

+ One of the year’s hottest topics was how ChatGPT was already changing education—from cutting corners for science homework, to writing entire theses. But some teachers believe that generative AI could actually make learning better. (Bonus: check out high school senior Rohan Mehta’s robust defense of ChatGPT in the classroom)

+ OpenAI’s hunger for data is coming back to bite it. The company’s AI services may be breaking data protection laws, and there is no resolution in sight. Read the full story.

+ Ilya Sutskever, OpenAI’s chief scientist, was one of the key executives to turn against and try to overthrow CEO Sam Altman in the recent OpenAI revolt. When Will Douglas Heaven met him earlier this year, Sutskever told him about his new priority—figuring out how to stop an artificial superintelligence from going rogue. Read the full story.
