Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
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.....»»

Low levels of common contaminants but high levels of other elements in waters linked to abandoned lithium mine
Lithium ore and mining waste from a historic lithium mine located west of Charlotte, North Carolina, are unlikely to contaminate surrounding waters with common pollutants such as arsenic and lead, according to a new study......»»
"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.....»»
Historically bad year for dolphin strandings on Cape Cod has scientists looking for answers
An unprecedentedly bad year for beached dolphins on Cape Cod might have to do with warming waters changing the availability of the animals' food, said scientists hoping to curb the strandings......»»

Cut into a Gibraltar cliff face overlooking the Alboran Sea, a cave opening leads back in time to one of the earliest manufacturing sites on the planet—a Neanderthal-built tar distillation oven hidden for 65,000 years......»»
Red squirrels are very flexible in shifting their daily routines to avoid urban threats, researchers find
Scientific investigations before and during the COVID-19 lockdown in Berlin in 2020 show that urban red squirrels are extremely flexible in adjusting their diurnal activities to the presence of humans, domestic dogs, domestic cats, and predators such.....»»
Greenland"s meltwater will slow Atlantic circulation, climate model suggests
A team of climate scientists in Germany and China has found evidence, using a climate model, that in the coming years, freshwater inputs to the Irminger Sea Basin will have the biggest impact on the Atlantic Meridional Overturning Circulation (AMOC)......»»
Scientists uncover cross-species neural mechanism for early detection of life motion in visual processing
Visual systems of both humans and animals can detect life motion from the environment at the earliest stage of visual processing, research by scientists from the Chinese Academy of Sciences (CAS) uncovered......»»
Horrifying medical device malfunction: Abdominal implant erupts from leg
Suspicious deaths, perforated sheep veins went unreported before device hit market. On May 7, 2011, Georgia resident Tonya Brand noticed a pain on the inside of her right thigh. A.....»»
Madagascar"s huge ocean algae bloom was caused by dust from drought-stricken southern Africa
Scientists have found new evidence that desertification, potentially linked to global warming, leads to large amounts of nutrient-rich dust landing in the sea, causing ocean algae to grow rapidly. Biological oceanographer John A. Gittings and an inte.....»»
Life in the world"s deepest seas: The challenge of finding 1,000 new marine species by 2030
Oceans cover 71% of the Earth's surface, but despite their immense size and impact on the planet, we know very little about them. While many of us might associate the sea with relaxing holidays on tropical beaches, the ocean is nothing but cold, dark.....»»
Neither desolate nor empty: Deep-sea floor teems with life
The Arctic deep sea harbors significant oil and natural gas reserves along with valuable resources such as rare earths and metals. Climate change and melting ice are facilitating access to these resources, which presents economic opportunities but al.....»»
Climate adaptation knowledge varies between socioeconomic groups, finds study
Since infrastructure in South Florida is vulnerable to the consequences of climate change, including rising sea levels, voters are tasked with deciding if they are willing to invest public money in strategies designed to mitigate these issues......»»
Could a multivitamin help save coral reefs? Preliminary data says yes
Like humans, coral reefs rely on nutrients in the environment surrounding them. Researchers at Woods Hole Oceanographic Institution (WHOI) have been lab testing nutrient-infused tiles to determine whether they would boost the immune system of corals,.....»»
The hidden disease risks of modern housing developments in rural Africa
Tamika Lunn went to Kenya looking for bats. Her task, as a postdoctoral researcher in the lab of U of A biologist Kristian Forbes, was to catch bats to understand if, when and why they carried viruses. A spillover of a bat virus to humans could lead.....»»
Lonely dolphin in Baltic Sea found to be talking to himself
A team of marine biologists at the University of Southern Denmark has discovered a solo male dolphin living in the Baltic Sea, who appears to be talking to himself. In their paper published in the journal Bioacoustics, the group describes how they an.....»»
How humans evolved to be "energetically unique"
Humans, it turns out, possess much higher metabolic rates than other mammals, including our close relatives, apes and chimpanzees, finds a Harvard study. Having both high resting and active metabolism, researchers say, enabled our hunter-gatherer anc.....»»
Flies carry bacteria, and some are resistant to antibiotics—evidence from three South African hospices
