A universal cancer vaccine in development could help rev up the immune system against tumors and supercharge the effects of existing cancer therapies, an animal study suggests. Similar to vaccines for viral infections like the flu, many cancer vaccines are designed to help the immune system recognize specific proteins. However, while conventional vaccines aim to … Read more
Google has harnessed motion sensors on more than 2 billion smartphones to create an earthquake early-warning system that’s as effective as standard seismometers, a new study reveals. Between 2021 and 2024, the company’s Android Earthquake Alerts (AEA) system captured more than 11,000 quakes through smartphone accelerometers and issued more than 1,200 alerts to Android users … Read more
Half-forgotten memories can be resurrected using “mental time travel,” a new study suggests. The research, published Monday (July 28) in the journal PNAS, showed that a person can rejuvenate their fading memories by recalling the emotions and thoughts they had when they first stored that memory. In fact, the researchers found that the refurbished memories … Read more
Memories of places “drift” across the brain as they are carried by different sets of neurons over time, a new study in mice suggests. Historically, neuroscientists thought that memories of locations and features of our immediate environment were encoded by specific “place cells.” These place cells, located in a key memory center called the hippocampus, … Read more
The Western Roman Empire famously ended in A.D. 476 when its last emperor abdicated the throne. But the city of Rome continued on. So what happened to the “Eternal City” after it was no longer the capital of one of the largest and most enduring empires ever seen? In the century after the empire’s fall, … Read more
Scientists have created a prototype robot that can grow, heal and improve itself by integrating material from its environment or by “consuming” other robots. It’s a big step forward in developing robot autonomy, the researchers say. The researchers coined the term “robot metabolism” to describe the process that enables machinery to absorb and reuse parts … Read more
As many as 200 worlds beyond our solar system discovered by astronomers may be larger than estimated, which could influence the search for extraterrestrial life. That’s the theory of a team of researchers who looked at hundreds of extrasolar planets, or exoplanets, observed by NASA’s Transiting Exoplanet Survey Satellite (TESS). TESS hunts exoplanets by catching … Read more
Mars was a rainier, wetter place than planetary scientists previously thought, according to a new study of ancient, inverted river channels that span more than 9,000 miles (14,484 kilometers) in the Red Planet’s southern Noachis Terra region. “Our work is a new piece of evidence that suggests that Mars was once a much more complex … Read more
Our solar system has been around for 4.6 billion years. While that sounds like a long time, it’s just a blip in the 13.8 billion-year story of the universe. And one day, the solar system will cease to exist. But when will the solar system end? And how will it die out? The answers to … Read more
You can use up all the storage on your phone or max out your computer’s drive, but can you use up all the memory space in your brain? Despite how you might feel before an exam or after a sleepless night before a work deadline, neuroscientists say that for a typical, healthy brain, memory capacity … Read more
