Viewer impatience may explain why ads lasting ten seconds or less outperform longer spots‎

A research team led by professor Inyoung Chae of Sungkyunkwan University (SKKU), together with professor Beth L. Fossen of Indiana University and professor Philip Kim of Texas Christian University in the United States, has demonstrated that ultrashort "micro ads" lasting 10 seconds or less are significantly more effective than longer, more elaborate advertisements at driving immediate online visits and consumer engagement.

The 2025 Kamchatka tsunami kept the Pacific ringing for more than ten hours. Its rhythm could help tsunami warnings‎

On July 29, 2025, at 23:24 Universal Time, a long stretch of seafloor off Russia's Kamchatka Peninsula was thrust upward. The magnitude 8.8 earthquake was the largest on Earth since the Tohoku earthquake of 2011, according to the U.S. Geological Survey, and within minutes a tsunami was spreading across the Pacific. Warnings went out from Japan to Chile. On Shumshu, in the Kuril Islands, the water splashed up to about 19 meters (62 feet) high.

Global pollination analysis reveals climate explains specialized partnerships better than latitude‎

An international study led by researchers from Charles University in Prague (CUNI) and the Biology Centre of the Czech Academy of Sciences (BC CAS) has mapped how closely flowering plants and their pollinators depend on each other.

Salivary gland mini-organs grown from pluripotent stem cells offer potential path to treating severe dry mouth‎

Extreme dry mouth, caused by radiation used to treat cancer and by autoimmune diseases such as Sjögren's disease, radically affects quality of life for sufferers. It can hamper speaking, swallowing and eating, and for years has seemed an intractable problem.

Engineer brings 'surgineering' mindset to future of medicine‎

Farshid Alambeigi refers to one of his most ambitious research efforts as "the sci-fi project." The idea lives up to the name. He is developing robotic technology that could one day help manufacture living tissue—potentially even functioning organs—for transplantation.

How the biological clock regulates phases of wakefulness‎

The circadian clock is an internal biological system that regulates sleep-wake cycles, as well as many physiological functions such as body temperature and hormone production. In many animals, this clock relies on a network of neurons that generates rhythms of approximately 24 hours.

Google DeepMind develops invisible watermarks for AI-designed proteins‎

Watermarks have long protected everything from bank notes and fine art to digital photographs and software, helping prove authenticity and trace an object's origin. Their main function is to protect copyright and verify authenticity.

The ocean as a medicine cabinet: Researchers search for useful microbes‎

New medicines, crop protection products and treatments for fish diseases could have their origins on the seabed. That is where project coordinator Gilles van Wezel and project manager Mariana Avalos Garcia, both biologists in Leiden, together with their colleagues, searched for microorganisms that produce useful compounds. Their search took them to sponges, algae, fish and salt-tolerant plants.

Machine learning detects bacterial invasion and DNA damage in human cells‎

When scientists assess how dangerous a bacterium is, the first question often seems simple: Can it be stopped or killed? In microbiology and antibiotic research, one of the classic readouts has been whether a bacterium can grow in the presence of a given treatment. The bacterium either grows or it does not. The drug either stops it or it does not.

EarthCARE's view of volcanic plume boosts air safety‎

Anak Krakatau, which means Child of Krakatoa, has been active sporadically since it emerged from the sea at the beginning of the last century in the caldera formed after the 1883 eruption of Mount Krakatoa.
