Google on Wednesday revealed that it suspended over 39.2 million advertiser accounts in 2024, with a majority of them identified and blocked by its systems before it could serve harmful ads to users.

In all, the tech giant said it stopped 5.1 billion bad ads, restricted 9.1 billion ads, and blocked or restricted ads on 1.3 billion pages last year. It also suspended over 5 million accounts for scam-related violations.

In comparison, Google suspended over 12.7 million advertiser accounts, stopped 5.5 billion bad ads, restricted 6.9 billion ads, and blocked or restricted ads on 2.1 billion pages in 2023.

Sound doesn’t just enter your ears – it may actually talk to your cells. New research out of Kyoto University shows that acoustic waves, even those in the audible range, can alter cellular behavior. Using specially designed equipment, scientists found that sound can suppress the formation of fat ce

Tissue from other organs, such as rat hearts and livers, has also been successfully cryopreserved and revived before. Whether this could eventually translate to putting an entire organ—or even an entire organism—in a state of suspended animation requires future research. Some animals produce their own cryoprotectants as they transition to a state of torpor to avoid harsh winters. This is something else scientists could learn from in the pursuit of artificial suspended animation. Alien and Foundation are onto something. Putting humans into a state of suspended animation during spaceflight would drastically reduce the risk of tissue damage caused by microgravity and extreme radiation. No one is trekking to Mars—at least not yet—so we still have time. But even just the thought is no less tantalizing.

Scientists in Korea achieved the first experimental realization of bound states in the continuum in a single resonator, opening doors to ultra-efficient wave control for future tech. A research team from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University has ach

An international study published in Communications Earth & Environment has advanced earthquake simulations to better anticipate the rupture process of large earthquakes.

Using data for the Turkey earthquake of February 2023, the scientists have developed a detailed 3D dynamic model that provides a more accurate understanding of the strong shaking during this earthquake and hence information for future seismic hazard assessments. The research was led by King Abdullah University of Science and Technology (KAUST) Professor Martin Mai and scientist Bo Li.

The Turkey earthquake was responsible for the death of tens of thousands of people. It was marked by a doublet, which describes two separated by a short time. The first fractured a long stretch of the fault approximately 350 km long, breaking different sections in succession. Just hours later, a second massive rupture followed, amplifying the destruction. Doublets do not show typical aftershock behavior and are a challenge to mathematically describe.

The room is crowded and noisy. There are conversations all around, and the residual smell of popcorn and beer hangs in the air. Yet two women meeting for the first time can judge within minutes whether they have the potential to be friends—guided as much by smell as any other sense, according to new Cornell psychology research.

“People take a lot in when they’re meeting face to face. But , which people are registering at some level, though probably not consciously, forecasts whether you end up liking this person,” said Vivian Zayas, professor of psychology in the College of Arts and Sciences (A&S). “It’s amazing, our attunement to other people, even without being consciously aware of how in tune we are.”

In a study of heterosexual women, Zayas and first author Jessica Gaby, Ph.D., found that personal, idiosyncratic preferences based on a person’s everyday scent, captured on a T-shirt, predicted how much women liked their interaction partner following four-minute chats across a table in a crowded room. These face-to-face conversations, in turn, influenced how participants later judged the T-shirt scent alone.
