Published Molecular fossils shed light on ancient life
(via sciencedaily.com)
Original source 
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published Study reshapes understanding of mass extinction in Late Devonian era
(via sciencedaily.com)
Original source 
A recently published study puts forth a new theory that volcanic eruptions combined with widespread ocean detoxification pushed Earth's biology to a tipping point in the Late Devonian era, triggering a mass extinction.
Published North Korea and beyond: AI-powered satellite analysis reveals the unseen economic landscape of underdeveloped nations?
(via sciencedaily.com)
Original source 
A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions with limited statistical data (e.g., North Korea), supporting international efforts to propose policies for economic growth and poverty reduction in underdeveloped countries. The research team plans to make this technology freely available for use to contribute to the United Nations' Sustainable Development Goals (SDGs).
Published Training algorithm breaks barriers to deep physical neural networks
(via sciencedaily.com)
Original source 
Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware.
Published First global estimate of marine aquarium trade to encourage sustainable practices
(via sciencedaily.com)
Original source 
New research estimates 55 million marine organisms worth $2.15bn are sold in the marine aquarium trade each year, making it as valuable as global fisheries such as tuna.
Published Giant doubts about giant exomoons
(via sciencedaily.com)
Original source 
The extrasolar planets Kepler-1625b and Kepler-1708b are supposedly the home worlds of the first known exomoons. A new study now comes to a different conclusion.
Published Three proposals from researchers to meet EU climate goals
(via sciencedaily.com)
Original source 
The ability to meet EU climate goals is enhanced by investing in new technologies that remove carbon dioxide from the atmosphere. Although it is currently unprofitable for both companies and countries to do so, there are solutions to make it financially viable.
Published Study: International scientists believe lack of women in physics tied to personal preference, but viewpoint ignores gender norms
(via sciencedaily.com)
Original source 
Fewer women pursue careers in physics than biology, and scientists from around the world believe these differences come down to personal preferences, according to a new study of international scientists. The study's researchers warn that merely chalking this imbalance up to individual choice may diminish the push for gender equality in the sciences.
Published Manipulation of gut microbiota with flaxseed could reduce breast cancer risk
(via sciencedaily.com)
Original source 
A new study demonstrates that the human gut microbiome may be a factor in breast health.
Published How ChatGPT could help first responders during natural disasters
(via sciencedaily.com)
Original source 
Researchers train AI to accurately recognize addresses and other location descriptions in Hurricane Harvey social media posts.
Published Magnetization by laser pulse
(via sciencedaily.com)
Original source 
To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team has discovered some time ago that a certain iron alloy can be magnetized with ultrashort laser pulses.
Published Growing biofilms actively alter host environment
(via sciencedaily.com)
Original source 
Dental plaque, gut bacteria and the slippery sheen on river rocks are all examples of biofilms, organized communities of microorganisms that colonize our bodies and the world around us. A new study reveals exactly how growing biofilms shape their environments and fine-tune their internal architecture to fit their surroundings. The findings may have implications for a wide variety of applications, from fighting disease to engineering new types of living active materials.
Published Polaritons open up a new lane on the semiconductor highway
(via sciencedaily.com)
Original source 
On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.'
Published Urbanization increases seasonal differences in plant-pollinator networks
(via sciencedaily.com)
Original source 
Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.
Published Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans
(via sciencedaily.com)
Original source 
Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign.
Published Wasps that recognize faces cooperate more, may be smarter
(via sciencedaily.com)
Original source 
A new study of paper wasps suggests social interactions may make animals smarter. The research offers behavioral evidence of an evolutionary link between the ability to recognize individuals and social cooperation.
Published Tiny llama nanobodies neutralize different noroviruses: Can they improve human anti-viral therapies?
(via sciencedaily.com)
Original source 
Researchers investigated a novel strategy to neutralize human noroviruses. They tested the ability of tiny antibodies produced by llamas, called nanobodies, to effectively neutralize human norovirus infection in the lab. The unexpected findings reveal that nanobodies could be developed as a therapeutic agent against human norovirus.
Published Sister climate cities, utility data predict future water, electricity demands
(via sciencedaily.com)
Original source 
Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close to what other cities are predicted to experience in the future -- to assess how climate change may impact residential water and electricity use across 46 cities in the United States.
Published It turns out, this fossil 'plant' is really a fossil baby turtle
(via sciencedaily.com)
Original source 
Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
Published Geoscientists map changes in atmospheric carbon dioxide over past 66 million years
(via sciencedaily.com)
Original source 
An international consortium of geoscientists has reconstructed atmosphereric levels of carbon dioxide going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years.
