Attosecond imaging made possible by short and powerful laser pulses
Extremely short pulses of laser light with a peak power of 6 terawatts (6 trillion watts)—roughly equivalent to the power produced by 6,000 nuclear power plants—have been realized by two RIKEN physicists. This achievement will help further develo.....»»
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much o.....»»
NASA is seeking a faster, cheaper way to bring Mars samples to Earth
NASA's plan to bring samples from Mars back to Earth is on hold until there's a faster, cheaper way, space agency officials said Monday......»»
Supporting the future of Mars exploration with supercomputers
You may have flown a flight simulator in a computer game or at a science museum. Landing without crashing is always the hardest part. But that's nothing compared to the challenge that engineers are facing to develop a flight simulation of the very la.....»»

Machine learning could help reveal undiscovered particles within data from the Large Hadron Collider
Scientists used a neural network, a type of brain-inspired machine learning algorithm, to sift through large volumes of particle collision data. Particle physicists are tasked with mining this massive and growing store of collision data for evidence.....»»
NASA discovered bacteria that wouldn"t die. Now it"s boosting sunscreen.
While disinfecting spacecraft headed for Mars, NASA found a stubborn type of bacteria that was tough to clean but great at withstanding UV radiation. Many people associate NASA with exploring new worlds in space, but few know it's also finding.....»»
Chemists devise easier new method for making a common type of building block for drugs
Ring-shaped chemical structures called saturated heterocycles are found in most FDA-approved drugs but are often difficult to create. Scripps Research chemists have just developed a surprisingly easy method for making many of these sought-after compo.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
Theories that explain the crisis in democracy are inadequate for Latin America, experts say
The theories offered by the dominant literature in political science today to try to explain the sources of the political polarization that has endangered democracy around the world are adequate for the United States and Europe, but do not make sense.....»»
A new type of seismic sensor to detect moonquakes
During the Apollo missions of the 1970s, several seismometers were flown to the moon, where they collected data on lunar seismic trembling for eight years. The data showed some lunar quakes were as powerful as a magnitude 5......»»
NASA technology helps guard against lunar dust
Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the moon or Mars, it is a significant hazard that must be mitigated. That's why researchers at NASA's Kennedy Space Center in Florida are s.....»»

Learn about the O.J. Simpson trial from CNN"s ancient "90s website
It's impossible to explain how central O.J. Simpson's trial for the murder of his former wife was to American culture in the 1990s. But CNN's internet archive does a decent job of documenting it. O.J. Simpson, perhaps the most infamous celebrit.....»»
Earthquakes may not be primary driver of glacial lake outburst floods
Glacial lakes form when meltwater is trapped behind a dam, usually glacial ice, bedrock or a type of moraine (terminal types being an unconsolidated pile of debris at the maximum extent of the glacier). When a dam fails, the resulting sudden release.....»»
AT&T: Data breach affects 73 million or 51 million customers. No, we won’t explain.
When the data was published in 2021, the company said it didn't belong to its customers. Enlarge (credit: Getty Images) AT&T is notifying millions of current or former customers that their account data has been compromis.....»»
Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments that have fundamental lim.....»»
Researchers investigate effectiveness of shipping alliances
Research published in the International Journal of Shipping and Transport Logistics has looked at the various factors that affect the overall effectiveness of shipping alliances in the container shipping industry. These alliances, formed as cooperati.....»»
Personality type can help predict who"s single or in a relationship, and how happy they are, says study
The phrase "single life" may conjure images of a busy "Sex and the City"-like social calendar, packed with dates and drama. But researchers at the University of Toronto say that most singles are actually introverts—a far cry from the extroverted st.....»»
Physicists discover a novel quantum state in an elemental solid
Physicists have observed a novel quantum effect termed "hybrid topology" in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation quantum science and.....»»
