Published Researchers map genome for cats, dolphins, birds, and dozens of other animals
(via sciencedaily.com) Original source Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Published A long-lasting neural probe
(via sciencedaily.com) Original source An interdisciplinary team of researchers has developed a soft implantable device with dozens of sensors that can record single-neuron activity in the brain stably for months.
Published Use it or lose it: How seagrasses conquered the sea
(via sciencedaily.com) Original source Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.
Published Chats with AI shift attitudes on climate change, Black Lives Matter
(via sciencedaily.com) Original source People who were more skeptical of human-caused climate change or the Black Lives Matter movement who took part in conversation with a popular AI chatbot were disappointed with the experience but left the conversation more supportive of the scientific consensus on climate change or BLM. This is according to researchers studying how these chatbots handle interactions from people with different cultural backgrounds.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Humpback whales move daytime singing offshore
(via sciencedaily.com) Original source New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Published Computer scientists invent simple method to speed cache sifting
(via sciencedaily.com) Original source Computer scientists have invented a highly effective, yet incredibly simple, algorithm to decide which items to toss from a web cache to make room for new ones.
Published Misinformation and irresponsible AI -- experts forecast how technology may shape our near future
(via sciencedaily.com) Original source From misinformation and invisible cyber attacks, to irresponsible AI that could cause events involving multiple deaths, expert futurists have forecast how rapid technology changes may shape our world by 2040.
Published What coffee with cream can teach us about quantum physics
(via sciencedaily.com) Original source A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published Offshore wind farms are vulnerable to cyberattacks
(via sciencedaily.com) Original source Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.
Published Marine heat waves trigger shift in hatch dates and early growth of Pacific cod
(via sciencedaily.com) Original source Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.
Published New research guides mathematical model-building for gene regulatory networks
(via sciencedaily.com) Original source A newly published study provides guidance for building accurate mathematical models for gene regulatory networks.
Published Don't blame the sharks: Why more hooked tarpon are being eaten
(via sciencedaily.com) Original source In wave-making research, a team of biologists has quantified the rate at which great hammerhead sharks are eating Atlantic tarpon hooked by anglers at Bahia Honda, Florida -- one of the prime tarpon fishing spots in the Florida Keys.
Published Manipulated hafnia paves the way for next-gen memory devices
(via sciencedaily.com) Original source A new study outlines progress toward making bulk ferroelectric and antiferroelectric hafnia available for use in a variety of applications, including high-performance computing.
Published Researchers unveil new way to counter mobile phone 'account takeover' attacks
(via sciencedaily.com) Original source Computer science researchers have developed a new way to identify security weaknesses that leave people vulnerable to account takeover attacks, where a hacker gains unauthorized access to online accounts.
Published The megalodon was less mega than previously believed
(via sciencedaily.com) Original source A new study shows the Megalodon, a gigantic shark that went extinct 3.6 million years ago, was more slender than earlier studies suggested. This finding changes scientists' understanding of Megalodon behavior, ancient ocean life, and why the sharks went extinct.
Published DNA origami folded into tiny motor
(via sciencedaily.com) Original source Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
Published Self-powered sensor automatically harvests magnetic energy
(via sciencedaily.com) Original source Researchers have designed a self-powering, battery-free, energy-harvesting sensor. Using the framework they developed, they produced a temperature sensor that can harvest and store the energy from the magnetic field that exists in the open air around a wire.
Published Sea otters helped prevent widespread California kelp forest declines over the past century
(via sciencedaily.com) Original source The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.
