Perfection: The enemy of evolution
Scientists are often trained to seek out the absolute best solution to a given problem. On a chalk board, this might look something like drawing a graph to find a function's minimum or maximum point. When designing a turbojet engine, it might mean tw.....»»
Denis Villeneuve breaks down the evolution of sandworms in "Dune: Part Two"
The sandworms we meet in "Dune: Part Two" serve a different role from those in "Dune." Director Denis Villeneuve tells us why. The sandworms we see in Dune: Part Two couldn't be farther from those we see in the first Dune. Yes, they share the s.....»»
JCDC’s strategic shift: Prioritizing cyber hardening
In this Help Net Security interview, Geoffrey Mattson, CEO of Xage Security, discusses the evolution of the Joint Cyber Defense Collaborative (JCDC) since its 2021 inception and tackles its 2024 strategic priorities in response to escalating cyber th.....»»
Similar genetic elements underlie vocal learning in mammals
The vocalizations of humans, bats, whales, seals and songbirds vastly differ from each other. Humans and birds, for example, are separated by some 300 million years of evolution. But scientists studying how these animals learn to "speak" have time an.....»»
Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals
A new paper published in The Quarterly Review of Biology examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology—habituation and neural adaptation—on the efficacy of mate choice signal.....»»

Mobile application development has experienced a radical pathway, traversing an evolutionary course that calibrates with the pacing of technological advancements and the changing perception of users. The evolution from the simple utilities of the yes.....»»
New findings suggest convergent evolution of algal CO₂-fixing organelles
Researchers at the University of Tsukuba identified the proteins of a CO2-fixing organelle, namely, "pyrenoid," in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independ.....»»
Eco-friendly catalyst and materials research explores pathways to renewable energy
The search for sustainable and affordable energy conversion technologies has highlighted the importance of the oxygen reduction and oxygen evolution reactions (ORR and OER). These processes are crucial for the efficiency of devices such as fuel cells.....»»
New measurement captures clearer picture of our galaxy and beyond
With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to measure the universe's origin and evolution more accurately......»»
Earth"s early evolution: Fresh insights from rocks formed 3.5 billion years ago
Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there was no ozone layer. It was a dynamic and evolving.....»»
Killer instinct drove evolution of mammals" predatory ancestors, scientists suggest
The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers at the University of Bristol and the Open University suggest......»»
Study finds a smoking gun for the spread and evolution of antibiotic resistance
Biomedical engineers at Duke University have uncovered a key link between the spread of antibiotic resistance genes and the evolution of resistance to new drugs in certain pathogens......»»
Biology textbooks do not provide students with comprehensive view of science of sex and gender, say professors
The teaching of science has long generated controversy in the United States—from evolution in the early 20th century to climate change today. Debates have also often emerged around how textbooks teach concepts related to social groups, and in parti.....»»
Astronomers observe the effect of dark matter on the evolution of the galaxies
Dark matter comprises around 85% of all the matter in the universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection difficult. Its existence is inferred from its gravitational.....»»
Science in times of crisis: Lessons from Fukushima and WWII
Collective memory is one way to ensure that past mistakes in the evolution of science systems are not repeated after a crisis, disaster or conflict according to a University of Tokyo historian who has contributed to the International Science Council'.....»»
The cultural evolution of collective property rights for sustainable resource governance
Community-based natural resource management has been dominated for several decades by the design principles of Nobel Prize laureate Elinor Ostrom. These principles provide guidelines for improving the governance of resource systems, from small-scale.....»»
Ancient retroviruses played a key role in the evolution of vertebrate brains, suggest researchers
Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains......»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
When an enemy invades, defenders are ferried to the site to neutralize the marauders. In the human body, a protein carrier called SPNS2 transports S1P molecules from endothelial cells to rally immune cell response in infected organs and tissues......»»
