The intricate dance between waves, wind, and gliding pelicans explored
- ScienceDaily
- 21/4/21 22:00
It's a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple. Researchers have recently developed a theoretical model that describes how the ocean, the wind and the birds in flight interact.
Detailed look at intriguing property of chiral materials

Study explains 'cocktail party effect' in hearing impairment
- ScienceDaily
- 21/4/21 22:00
Plenty of people struggle to make sense of a multitude of converging voices in a crowded room. Commonly known as the 'cocktail party effect,' people with hearing loss find it's especially difficult to understand speech in a noisy environment. New research suggests that, for some listeners, this may have less to do with actually discerning sounds. Instead, it may be a processing problem in which...

Cracking the code of the Dead Sea Scrolls
- ScienceDaily
- 21/4/21 21:12
The Dead Sea Scrolls, discovered some seventy years ago, are famous for containing the oldest manuscripts of the Hebrew Bible (Old Testament) and many hitherto unknown ancient Jewish texts. But the individual people behind the scrolls have eluded scientists, because the scribes are anonymous. Now, by combining the sciences and the humanities, researchers have cracked the code, which enables them...

Researchers have found that artificial intelligence algorithms can influence people's preferences for fictitious political candidates or potential romantic partners, depending on whether recommendations were explicit or covert.
Air pollution data in five Chinese cities: Local vs. U.S. monitoring stations
- ScienceDaily
- 21/4/21 21:12
When air quality in China is poor, locally reported air pollution measurements diverge from U.S. embassy-reported measurements more than would be expected by random chance, finds an analysis of air pollution data from five large Chinese cities.
