Stockholm-based learning platform Sana has announced a suite of generative AI tools along with an extension to its Series B round, bringing its total funding to $80 million.

Inside companies, information is often scattered across silos, buried in systems and locked in different formats, making it inaccessible to employees when they need it most, says Swedish entrepreneur Joel Hellermark. The 26-year-old hopes to help companies tackle this problem through his learning platform Sana, which uses AI to create an index for companies’ information, allowing employees to query and search it and perform tasks like creating training courses and summarizing and translating information.

Workplace collaboration tools are supposed to make things easier. I think they just make everything more complicated.

From my personal experience, these tools require quite a bit of manual input from users and are limited in their scopes of functionality. Strategy documents, proposals, roadmaps, meetings and notes may be found living in separate apps.

Notion hopes that AI can help cut down on the fragmentation within this space with its new product, Notion Projects. Projects aims to connect all aspects of collaboration in one place, making it easier for teams to plan, manage, and execute work, with the help of AI LLMs from OpenAI and Anthropic.

Vectara is continuing to grow as an AI powered conversational search platform with new capabilities announced today that aim to improve generative AI for business data.

The Santa Clara, Calif.- based startup emerged from stealth in Oct. 2022, led by the former CTO and founder of big data vendor Cloudera. Vectara originally branded its platform as a neural search-as-a-service technology. This approach combines AI-based large language models (LLMs), natural language processing (NLP), data integration pipelines and vector techniques to create a neural network that can be optimized for search.

Is this Mars thing really happening? SpaceX did its first test launch of Starship this spring, the rocket that it’s developing to send to Mars. But getting to Mars is still a long way off. So does SpaceX have the funding and business plan to pull it off?For sponsor-free episodes of The Indicator from Planet Money, subscribe to Planet Money+ via Apple Podcasts or at plus.npr.org.

A new study finds a chemical formed when we digest a widely used sweetener is “genotoxic,” meaning it breaks up DNA. The chemical is also found in trace amounts in the sweetener itself, and the finding raises questions about how the sweetener may contribute to health problems.

At issue is sucralose, a widely used artificial sweetener sold under the trade name Splenda®. Previous work by the same research team established that several fat-soluble compounds are produced in the gut after sucralose ingestion. One of these compounds is sucralose-6-acetate.

Our new work establishes that sucralose-6-acetate is genotoxic. We also found that trace amounts of sucralose-6-acetate can be found in off-the-shelf sucralose, even before it is consumed and metabolized.

Thinking of X-rays might trigger memories of broken bones or dental check-ups. But this extremely energetic light can show us more than just our bones: it is also used to study the molecular world, even biochemical reactions in real-time. One issue, though, is that researchers have never been able to study a single atom with X-rays. Until now.

Scientists have been able to characterize a single atom using X-rays. Not only they were able to distinguish the type of atoms they were seeing (there were two different ones), but they also managed to study the chemical behavior these atoms were showing.

“Atoms can be routinely imaged with scanning probe microscopes, but without X-rays, one cannot tell what they are made of. We can now detect exactly the type of a particular atom, one atom-at-a-time, and can simultaneously measure its chemical state,” senior author Professor Saw Wai Hla, from the University of Ohio and the Argonne National Laboratory, said in a statement.

SAN FRANCISCO (Reuters) — Tesla Inc has doubled discounts on some already made new Model 3 electric cars and offered discounts on the Model Y and others in its U.S. inventory to entice buyers amid economic uncertainty, rising competition and the upcoming redesign of its mainstay model.

In California, a Model 3 variant in inventory was priced at $42,060, a discount of $2,680 to the price of newly ordered cars, according to its website. That is double the $1,300 discount on Model 3 cars offered less than two weeks ago.

Physicists have long puzzled over why there is more matter in the Universe than its flipped twin, antimatter. Without this imbalance, the two types of material would have canceled out, leaving nothing but a boring glow in the vast emptiness of space.

Somehow, at some point, something changed in the way the Universe works on a fundamental level, favoring the mirrored state – or parity – of one kind of ‘stuff’ over the other.

Scientists have sought clues to this critical moment in the remnants of the Big Bang, including the cosmic microwave background and gravitational waves, without much luck.
