Crocodile evolution rebooted by Ice Age glaciations
Crocodiles are resilient animals from a lineage that has survived for over 200 million years. Skilled swimmers, crocodiles can travel long distances and live in freshwater to marine environments. But they can't roam far overland. American crocodiles.....»»
Gene flow in giraffes and what it means for their conservation
Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years, they have attained notoriety for a completely different reason: it has been suggested that instead of one giraffe species, there might be.....»»
Webb and Hubble telescopes affirm the universe"s expansion rate, but the puzzle persists
The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos......»»
Transitioning to memory-safe languages: Challenges and considerations
In this Help Net Security interview, Omkhar Arasaratnam, General Manager at the Open Source Security Foundation (OpenSSF), discusses the evolution of memory-safe programming languages and their emergence in response to the limitations of languages li.....»»
New study discovers how altered protein folding drives multicellular evolution
Researchers have discovered a mechanism steering the evolution of multicellular life. They identify how altered protein folding drives multicellular evolution......»»
Horizontal gene transfer: How fungi improve their ability to infect insects
Researchers at the Kiel Evolution Center have investigated for the first time in detail how a fungus important for biological plant protection can pass on an advantageous chromosome horizontally, using a previously little-studied way of exchanging ge.....»»
New study reveals the evolutionary nature of animal friendships
Biologists from Stockholm University and University of Neuchâtel present groundbreaking research shedding new light on the evolution of social bonds and cooperation among group-living animals. The study was published in the journal PNAS......»»
Scientists use James Webb Space Telescope to uncover clues about Neptune"s evolution
A ring of icy rocks orbiting our sun just beyond Neptune may give us a glimpse of how Neptune—and other objects in the outskirts of our solar system—were formed......»»
Sweet Security raises $33 million to identify and address cloud risks
Six months after coming out of stealth, Sweet Security is announcing a $33 million Series A funding round. The round was led by Evolution Equity Partners, joined by Munich Re Ventures and Glilot Capital Partners. Capitalizing on its strong market tra.....»»
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.....»»
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......»»
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......»»
