Using algorithms to decode the complex phonetic alphabet of sperm whales
The allure of whales has stoked human consciousness for millennia, casting these ocean giants as enigmatic residents of the deep seas. From the biblical Leviathan to Herman Melville's formidable Moby Dick, whales have been central to mythologies and.....»»
Scientists use acoustic data to track blue and fin whale occurrences in the Arctic
The long-term analysis of blue whale and fin whale vocalizations in the eastern Fram Strait offers valuable insights into seasonal and annual patterns regarding these species' occurrence in the region. For example, blue whales can primarily be heard.....»»
Capturing complex atoms in optical tweezers
A team led by Francesca Ferlaino has set a new milestone in atomic physics by trapping individual erbium atoms in optical tweezers for the first time. Taking advantage of erbium's complex electronic structure, which opens up new degrees of freedom an.....»»
Same plant, different tactic: Habitat determines response to climate, thale cress study finds
Plants need light to grow, but too much light can induce damage to the photosynthetic complex known as photosystem II. It is known that plants adapted to growing under full sun repair this light-induced damage more. But this repair activity slows dow.....»»
Fruit fly study offers new insights into sperm evolution
Sperm are the most diverse and rapidly evolving cell type. Why sperm have undergone such dramatic evolution is a mystery that has stumped biologists for more than a century......»»

Reading PDFs has become second nature, but when it comes to editing, converting, or even organizing PDF documents, the process can be cumbersome. UPDF has changed that, offering an AI-powered PDF solution that makes these complex tasks easier for Mac.....»»
Study finds opposing effects of short-term and continuous noise on western bluebird parental care
Research led by Kerstin Ozkan and published in PeerJ has uncovered the complex and contrasting effects of human-generated noise on Western Bluebird (Sialia mexicana) parental behavior, raising critical questions about how anthropogenic noise affects.....»»
First right whales of season gorge on critical food off Massachusetts, giving hope for a strong year
Scientists who study a critically endangered species of whale that lives off New England said encouraging early signs suggest the animals could have a strong season for feeding and breeding......»»
Biodiversity is not a luxury: Study explores the connection between wealth and ecosystem health
A new study suggests that a more complex understanding of how wealth and biodiversity are linked may help communities with little wealth achieve the levels of diversity typically associated with more affluent areas......»»
X-ray diffraction enables measurement of in-situ ablation depth in aluminum
When laser energy is deposited in a target material, numerous complex processes take place at length and time scales that are too small to visually observe. To study and ultimately fine-tune such processes, researchers look to computer modeling. Howe.....»»
New Zealanders save more than 30 stranded whales by lifting them on sheets
More than 30 pilot whales that stranded themselves on a beach in New Zealand were safely returned to the ocean after conservation workers and residents helped to refloat them by lifting them on sheets. Four of the pilot whales died, New Zealand's con.....»»
First successful test of wild minke whales reveals they have ultrasonic hearing
A team of marine biologists from Norway, the U.S. and Denmark has conducted the first hearing test of a live baleen whale. For their study published in the journal Science, the group corralled a pair of wild minke whales and recorded their brain wave.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»
Exploring the impact of offshore wind on whale deaths
In the winter of 2022–2023, nearly a dozen whales died off the coast of New Jersey, near the sites of several proposed wind farms. Their deaths prompted concern that related survey work being conducted in the area somehow contributed to their death.....»»
Algorithmic management raises concerns over worker autonomy
In more and more workplaces, important decisions aren't made by managers but by algorithms which have increasing levels of access to and control over workers. While algorithmic management can boost efficiency and flexibility (as well as enabling a ne.....»»
AI and genus-conditioned algorithms create precise simulation-ready models of 600,000 existing urban trees
The Irish philosopher George Berkely, best known for his theory of immaterialism, once famously mused, "If a tree falls in a forest and no one is around to hear it, does it make a sound?" What about AI-generated trees? They probably wouldn't make a s.....»»
"Genetic time machine" reveals complex chimpanzee cultures
In recent decades, scientists have clearly demonstrated that chimpanzees, like humans, pass on complex cultures such as tool use from generation to generation. But human culture has become vastly more sophisticated, from the Stone Age to the Space Ag.....»»
Video: Our sun is the star in a new simulation
NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar d.....»»
Fewer than 7% of global hotspots for whale-ship collisions have protection measures in place, researchers report
According to the fossil record, cetaceans—whales, dolphins and their relatives—evolved from four-legged land mammals that returned to the oceans beginning some 50 million years ago. Today, their descendants are threatened by a different land-base.....»»
Aquaculture researchers decode the genome of the African catfish to advance modern breeding approaches
Scientists at the Research Institute for Farm Animal Biology (FBN) in Dummerstorf have decoded the genome of the African catfish (Clarias gariepinus), in collaboration with international partners......»»
Social media has complex effects on adolescent well-being, and policymakers must take note
In late 2024, more than 20 years after the birth of Facebook, the impact of social media on our lives cannot be overstated. Initially underestimated by many in business, social media eventually came to be recognized for its power to enable workers to.....»»
