Published From square to cube: Hardware processing for AI goes 3D, boosting processing power
(via sciencedaily.com) Original source A breakthrough development in photonic-electronic hardware could significantly boost processing power for AI and machine learning applications. The approach uses multiple radio frequencies to encode data, enabling multiple calculations to be carried out in parallel. The method shows promise for outperforming state-of-the-art electronic processors, with further enhancements possible.
Published Pinpointing the emergence of muddy flavors in your fish
(via sciencedaily.com) Original source Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com) Original source Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
Published Drought conditions expose rivers to hotter water temperatures
(via sciencedaily.com) Original source A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors
(via sciencedaily.com) Original source The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published How to build greener data centers? Scientists say crank up the heat
(via sciencedaily.com) Original source Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.
Published Surprising discovery about coral's resilience could help reefs survive climate change
(via sciencedaily.com) Original source A team has studied the mountainous star coral, Orbicella faveolata, to determine whether coral populations that have survived higher temperatures can pass their heat tolerance on to their offspring. To the scientists' surprise, the results showed the opposite: The offspring from a population that is less heat-tolerant performed better when exposed to high temperatures than their counterparts from a heat-tolerant population. The findings counter the commonly held notion among scientists that if coral parents can handle the heat, so should their offspring.
Published Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
(via sciencedaily.com) Original source Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Published Study reveals our European ancestors ate seaweed and freshwater plants
(via sciencedaily.com) Original source Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.
Published Unique marimo threatened by rising lake temperatures
(via sciencedaily.com) Original source Rising lake water temperatures threaten the survival of marimo, unique algal balls found only in cold lakes. Researchers clarified that the warmer it gets, the more the inward decomposition outpaces the outward growth of these life forms, making them increasingly fragile.
Published New threat to Antarctic fur seals
(via sciencedaily.com) Original source Populations of charismatic animals have recovered since hunting ban but now struggle to find enough food.
Published Marine bacteria take a bite at plastic pollution
(via sciencedaily.com) Original source A bacterium found in the sea can degrade a plastic that otherwise resists microbial breakdown in marine environments.
Published New study confirms presence of flesh-eating and illness-causing bacteria in Florida's coastal waters following Hurricane Ian
(via sciencedaily.com) Original source When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
Published Climate change coping mechanism discovered in humble algae
(via sciencedaily.com) Original source One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.
Published What phytoplankton physiology has to do with global climate
(via sciencedaily.com) Original source Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.
Published Physicists demonstrate powerful physics phenomenon
(via sciencedaily.com) Original source In a new breakthrough, researchers have used a novel technique to confirm a previously undetected physics phenomenon that could be used to improve data storage in the next generation of computer devices.
Published Gray whales experience major population swings as a result of Arctic conditions
(via sciencedaily.com) Original source Dynamic and changing Arctic Ocean conditions have likely caused three major mortality events in the eastern North Pacific gray whale population since the 1980s.
Published Self-correcting quantum computers within reach?
(via sciencedaily.com) Original source Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.
Published Exploring parameter shift for quantum fisher information
(via sciencedaily.com) Original source Scientists have developed a technique called 'Time-dependent Stochastic Parameter Shift' in the realm of quantum computing and quantum machine learning. This breakthrough method revolutionizes the estimation of gradients or derivatives of functions, a crucial step in many computational tasks.
