Enabling agent-first process redesign | MIT Technology Review

In an agent-first enterprise, AI systems operate processes while humans set goals, define policy constraints, and handle exceptions. “You need to shift the operating model to humans as governors and agents as operators,” says Scott Rodgers, global chief architect and U.S. CTO of the Deloitte Microsoft Technology Practice. The agent-first imperative With technology budgets for AI expected to increase more than 70% over the next two years, AI agents, powered by generative AI, are poised to fundamentally transform organizations and achieve results beyond traditional automation. These initiatives have the potential to produce significant performance gains, while shifting humans toward higher value work. AI is advancing so quickly that static approaches to task automation will likely only produce incremental gains. Because legacy processes aren’t built for autonomous systems, AI agents require machine-readable process definitions, explicit policy constraints, and structured data flows, according to Rodgers. Further complicating matters, many organizations don’t understand the full economic drivers of their business, such as cost to serve and per-transaction costs. As a result, they have trouble prioritizing agents that can …

Published by Sam Flores

Deutschland sehnt sich nach einem Comeback, doch der versprochene Aufschwung der schwarz-roten Koalition lässt auf sich warten. Während traditionsreiche Parteien wie die SPD und die FDP schwächeln und die Union als Kanzlerpartei nach Orientierung sucht, regieren im Land eher Zweifel statt Tatendrang. In diesem Spezial analysiert Rixa Fürsen den Status Quo mit Ulf Poschardt, dem Herausgeber von Welt, Business Insider und POLITICO. Das Berlin Playbook als Podcast gibt es jeden Morgen ab 5 Uhr.

MIT researchers look to create a more ‘humble’ AI

MIT researchers look to create a more ‘humble’ AI

Published by Jenni Sidey

The problem with asking an AI for a diagnosis is not that it might be wrong. It is that it might be wrong and sound completely certain. That distinction matters considerably in medicine, where studies have shown that experienced ICU physicians will defer to AI recommendations even when their own clinical instincts push back, and where radiologists have been documented following incorrect AI suggestions despite contradictory visual evidence right in front of them. Confidence, it turns out, is persuasive regardless of whether it is warranted. A team of researchers led by MIT now argues that the solution is not smarter AI, at least not primarily. It is humbler AI. Their framework, published in BMJ Health and Care Informatics, attempts to engineer uncertainty into clinical AI systems so that when a model does not know something with confidence, it says so and asks questions instead of pressing forward with an authoritative-sounding answer.

An implant under the skin could replace insulin injections

An implant under the skin could replace insulin injections

Published by Jenni Sidey

A small device implanted just beneath the skin, roughly the size of a large postage stamp and weighing about two grams, kept diabetic mice and rats healthy for three months without a single dose of immunosuppressive medication. That result, published in the journal Device by researchers at MIT, represents a meaningful step toward something diabetes patients have long needed: a way to receive transplanted insulin-producing cells without the drugs that prevent the immune system from destroying them. The implanted device has a built-in mechanism for keeping living pancreatic islet cells alive. The substrate material protects the transplanted pancreatic islet cells by allowing them access to a continuous supply of oxygen generated within the substrate itself. This process occurs without the need for complex systems to supply oxygen. Instead, it uses moisture present within the body as the source for generating the oxygen needed for the islet cells. The concept of islet cell transplantation is not new. Physicians have known for many years that taking insulin-producing cells from a donor can restore normal glucose control. A …

Vermögenssteuer durch die Hintertür? Mit Moritz Schularick – POLITICO

Published by Sam Flores

Das Land braucht Reformen und einen Ausweg aus der Energiepreis-Falle des Iran-Krieges. Über die zwei aktuell drängendsten ökonomischen Baustellen spricht Rixa Fürsen in dieser Sonderfolge mit dem ⁠Präsidenten des Kiel Instituts für Weltwirtschaft (IfW), Moritz Schularick⁠. Erneut findet sich Deutschland in der Rolle des Zaungasts wieder: Wie schon bei der Invasion der Ukraine spürt das Land die Folgen eines Krieges, kann aber nur eingeschränkt handeln. Besonders in der Energiepolitik scheinen uns mangels Handhabe die Hände gebunden. Aber ist das wirklich so? Moritz Schularick zeigt Wege aus der totalen Abhängigkeit auf. Im Gespräch skizziert er eine mögliche strategische Energiepartnerschaft mit Frankreich, inklusive der Debatte um Atomstrom. Der Ökonom erklärt, warum staatliche Eingriffe gegen hohe Spritpreise das falsche Signal sind und wie bürokratische Kleinkriege in den Ministerien Deutschlands die Energie- und Sicherheitspolitik gefährden. Außerdem analysieren Rixa Fürsen und Moritz Schularick den neuen Reformeifer von Union und SPD. Schularick zeigt auf, warum eine Erhöhung der Mehrwertsteuer im Grunde eine verdeckte Vermögenssteuer wäre und wieso Politik und Öffentlichkeit endlich aufhören müssen, nur über den Erhalt der Auto- und Stahlindustrie …

MIT study suggests astrocytes play key role in brain memory storage

MIT study suggests astrocytes play key role in brain memory storage

Published by Jenni Sidey

The human brain holds a staggering number of connections, yet scientists have long struggled to explain how it stores so much information. A new study from MIT researchers suggests the answer may lie in cells once dismissed as simple support. For decades, neurons have taken center stage in memory research. These cells send electrical signals that allow the brain to process thoughts and store experiences. But neurons are only part of the story. The brain also contains billions of astrocytes, star-shaped cells that quietly surround and interact with neural networks. Now, a team led by researchers at MIT proposes that astrocytes may play a direct and powerful role in memory storage. Their findings offer a new way to think about how memories form and persist. “Originally, astrocytes were believed to just clean up around neurons, but there’s no particular reason that evolution did not realize that, because each astrocyte can contact hundreds of thousands of synapses, they could also be used for computation,” said Jean-Jacques Slotine, an MIT professor of mechanical engineering and brain and …

Expanding catalog of black hole collisions is rewriting the history of the universe

Expanding catalog of black hole collisions is rewriting the history of the universe

Published by Jenni Sidey

Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more than doubling the entire catalog built across the previous decade. The universe, it turns out, is not quiet. It is constantly shaking. The LIGO-Virgo-KAGRA Collaboration, an international partnership spanning observatories in the United States, Italy, and Japan, has published its fourth gravitational-wave catalog, GWTC-4.0, in a forthcoming special issue of Astrophysical Journal Letters. The collection represents the most comprehensive census yet of colliding black holes and neutron stars, and it is already pushing physics into territory no one has mapped before. “The beautiful science that we are able to do with this catalog is enabled by significant improvements in the sensitivity of the gravitational-wave detectors as well as more powerful analysis techniques,” said Nergis Mavalvala, dean of the MIT School of Science and a member of the collaboration. The timeline of observing runs covering a time span starting from 2015 and lasting up to the beginning of O4b on 2024 April 10. The periods in which …
