How to create an efficient governance control program
Your success as an organization, especially in the cyber realm, depends on your security posture. To account for the ongoing evolution of digital threats, you need to implement robust governance control programs that address the current control envir.....»»
Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era
Paleontologists have discovered a strange new species of marine lizard with dagger-like teeth that lived near the end of the age of dinosaurs. Their findings, published in Cretaceous Research, show a dramatically different ocean ecosystem to what we.....»»
How did evolution produce a firefly?
A new study looks at the development of a firefly's light-emitting organs. Enlarge (credit: Xinhua Fu) On one level, we have fireflies figured out. We know the enzyme they use to make light (called luciferase), as well a.....»»
Shortcut to success: Toward fast and robust quantum control through accelerating adiabatic passage
In work published in Physical Review Letters researchers at Osaka University's Institute of Scientific and Industrial Research (SANKEN) used "the shortcuts to the adiabaticity (STA)" method to greatly speed-up the adiabatic evolution of spin qubits......»»
Hanoi chokes as Vietnam capital tops most polluted cities list
Vietnamese capital Hanoi was blanketed by a thick haze of pollution on Tuesday that obscured high-rise buildings and left the city's nearly nine million people breathing toxic air......»»
Modeling the origins of life: New evidence for an "RNA World"
Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, allowing slight variations.....»»
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.....»»
The Future of Mobile App Development and Why Flutter is Leading the Way
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
