A first-of-its-kind stem cell transplant has changed the life of a man who was left blind in one eye following a firework accident.
A stunning Hubble image showcases a spiral galaxy seemingly intertwined with a nearby star—but looks can be deceiving!
This new Hubble Space Telescope.
The Hubble Space Telescope (often referred to as Hubble or HST) is one of NASA’s Great Observatories and was launched into low Earth orbit in 1990. It is one of the largest and most versatile space telescopes in use and features a 2.4-meter mirror and four main instruments that observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. It was named after astronomer Edwin Hubble.
Is NASA still Moonbound, or will the next giant leap mean skipping straight to Mars?
Speculation is mounting that the Trump administration may scale back or cancel NASA’s Artemis missions following the departure of a key official and Boeing’s plans to lay off hundreds of employees working on its lunar rocket.
Late Wednesday, NASA abruptly announced the retirement of longtime associate administrator Jim Free, effective Saturday.
ServiceNow, which provides businesses with outsourced IT and customer service support as well as other digital services, said it was buying the business process automation company Moveworks for $2.85 billion in cash and stock. The Santa Clara, California-based ServiceNow framed the acquisition around the burgeoning market for AI agents that can perform digital tasks for people, often involving the use of other software.
The company is among a clutch of competing software giants, including Salesforce, Microsoft, and Alphabet’s Google, that are building platforms that enable companies to automate work with AI agents. ServiceNow said the purchase would allow it to combine its own agentic AI and automation capabilities with Moveworks’ AI assistant, as well as Movework’s prowess in providing AI-based search tools that allow organizations to find information within their own large data pools.
Gina Mastantuono, ServiceNow’s president and chief financial officer, told Fortune that while ServiceNow’s AI agents primarily automate specific back-end tasks, Moveworks had built an elegant front-end AI assistant that can perform a wide range of different tasks.
The same interface works for both people requesting a task to be fulfilled and for the people who are normally responsible for fulfilling those requests. More than 90% of the customers that use Moveworks’ AI assistant have rolled it out to their entire workforce—a reach into the employee base that Mastantuono said was attractive to ServiceNow.
The combined companies would be able to build what ServiceNow said would be a powerful universal AI assistant, along with more perceptive AI-based enterprise search to find answers to requests, automate and complete everyday tasks, and increase productivity.

Part 3 of the groundbreaking but less-known theory of quantum mechanics proposed by Louis de Broglie in 1923. In this video de Broglie’s unification of wave and particles using his matter waves to show that Fermat’s principle of ray optics is equivalent to Maupertuis’ principle for the dynamics of particles. Although incomplete, this corresponds to the early development of de Broglie’s pilot-wave theory.

Although it’s not the first time this was hypothesized, this study is the first time researchers looked at the presence of gingipains within the brains of diseased patients. Even more, the patients themselves were never even diagnosed with Alzheimer’s.
“Our identification of gingipain antigens in the brains of individuals with AD and also with AD pathology but no diagnosis of dementia argues that brain infection with P. gingivalis is not a result of poor dental care following the onset of dementia or a consequence of late-stage disease, but is an early event that can explain the pathology found in middle-aged individuals before cognitive decline,” the authors explained.
While this isn’t a one-size-fits-all answer to what causes Alzheimer’s, it’s a step in the right direction to finding the reasoning behind this life-altering disease.
How will artificial intelligence affect the distribution of income and wealth this century? After falling through much of the 20th century, income inequality, measured as the fraction of income going to the richest 1% of residents, has been rising since the 1980s. The fraction has doubled in both China and the United States during that time, increased by 50% in Europe and one-third worldwide.
Industrialization dominated the economy before then, but starting in the ’70s and ’80s, capital took over as globalization increased, tax changes reduced progressivity and game-changing technologies were introduced rapidly.
The computer and personal computer revolution came first, followed by the Internet and the World Wide Web. Now artificial intelligence (AI) is beginning to make its mark in the world as a next-generation general-purpose technology.
Real-space quantum vortices are key to many phenomena in modern physics. New experiments provide the first proof of vortices in momentum space, raising the prospect of exploring novel orbitronic phenomena.
