Insight, involving representational change, can boost long-term memory. Here, in an fMRI study, the authors show that insight triggers stronger conceptual shifts in solution relevant brain regions and enhanced network integration, improving memory retention.
Large language models (LLMs) are remarkably versatile. They can summarize documents, generate code or even brainstorm new ideas. And now we’ve expanded these capabilities to target fundamental and highly complex problems in mathematics and modern computing.
Today, we’re announcing AlphaEvolve, an evolutionary coding agent powered by large language models for general-purpose algorithm discovery and optimization. AlphaEvolve pairs the creative problem-solving capabilities of our Gemini models with automated evaluators that verify answers, and uses an evolutionary framework to improve upon the most promising ideas.
AlphaEvolve enhanced the efficiency of Google’s data centers, chip design and AI training processes — including training the large language models underlying AlphaEvolve itself. It has also helped design faster matrix multiplication algorithms and find new solutions to open mathematical problems, showing incredible promise for application across many areas.
NASA’s Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.
A common assumption is that AGI won’t need any further training by humans. The reality is that AGI will surely need to further tap into human knowledge. Here’s why.
Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fiber optic networks.
The smartphone is a great example of the power of light. Inside the box, its electronic functionality works because of quantum mechanics. The front screen is an entirely photonic device: liquid crystals controlling light. The back too: white light-emitting diodes for a flash, and lenses to capture images.
We use the word photonics, and sometimes optics, to capture the harnessing of light for new applications and technologies. Their importance in modern life is celebrated every year on 16 May with the International Day of Light.
On March 15, 2024, near the peak of the current solar cycle, the sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of solar energetic particles. This solar activity led to stunning auroras across the solar system, including at Mars, where NASA’s Perseverance Mars rover made history by detecting them for the first time from the surface of another planet.
“This exciting discovery opens up new possibilities for auroral research and confirms that auroras could be visible to future astronauts on Mars’ surface,” said Elise Knutsen, a postdoctoral researcher at the University of Oslo in Norway and lead author of the Science Advances study, which reported the detection.
Engineers at NASA’s Jet Propulsion Laboratory in Southern California have revived a set of thrusters aboard the Voyager 1 spacecraft that had been considered inoperable since 2004. Fixing the thrusters required creativity and risk, but the team wants to have them available as a backup to a set of active thrusters whose fuel tubes are experiencing a buildup of residue that could cause them to stop working as early as this fall.
In addition, the mission needed to ensure the availability of the long-dormant thrusters before May 4, when the Earth-bound antenna that sends commands to Voyager 1 and its twin Voyager 2 went offline for months of upgrades.
Landslide-generated tsunamis pose a serious risk to coastal communities, particularly within narrow fjords where tall cliffs can trap and amplify waves. Scientists rely heavily on earthquake-based observation systems to issue tsunami warnings, but these methods don’t always capture localized ground movement caused by landslides.
Now, for the first time, scientists have detected tsunami waves caused by a landslide using data from a ship’s satellite receiver. The CIRES and CU Boulder-led research, published in Geophysical Research Letters, shows the potential for an approach to improving tsunami detection and warning, providing lifesaving information to coastal communities.
“Landslides into water can produce a tsunami, and some of them can be quite large and destructive,” said CIRES Fellow Anne Sheehan, a professor of Geological Sciences at CU Boulder and co-author of the study. “Scientists have captured larger, earthquake-induced tsunamis using ship navigation systems. Our team had equipment in the right place at the right time to show this method also works for landslide-generated tsunamis.”
Mindfulness-based therapy can offer significant relief for individuals who are still depressed after receiving treatment, according to a new clinical trial.
Researchers hope their findings, published in Lancet Psychiatry, could provide a new treatment pathway for people with depression who have not benefited from previous treatment.
The study, titled “Mindfulness-based cognitive therapy versus treatment as usual after non-remission with NHS Talking Therapies high-intensity psychological therapy for depression: a UK-based clinical effectiveness and cost-effectiveness randomised, controlled, superiority trial,” was led by a researcher from the University of Surrey.
Have you ever been stuck on a problem, puzzling over something for what felt like ages without getting anywhere, but then suddenly the answer came to you like a bolt from the blue?
We’ve all experienced that “aha! moment,” that sudden clarity or magical epiphany you feel when a new idea or perspective pops into your head as if out of nowhere.
Now, new evidence from brain imaging research shows that these flashes of insight aren’t just satisfying—they actually reshape how your brain represents information, and help sear it into memory.
