Published Nanoparticles for optimized cancer therapy



Pancreatic cancer is one of the deadliest types of cancers in humans. It is the fourth leading cause of cancer-related deaths in the western world. The early stages of the disease often progress without symptoms, so diagnosis is usually very late.
Published New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America



New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s



In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published Evolution of taste: Early sharks were able to perceive bitter substances



New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
Published No scientific evidence for cognitively advanced behaviors and symbolism by Homo naledi



A new study casts doubt on claims that Homo naledi, a small-brained hominin dating to between 335-241,000 years ago, deliberately buried their dead and produced rock art in Rising Star Cave, South Africa. Recent articles suggested the recent excavations at the Rising Star Cave system provided evidence of at least three burial features, two in the Dinaledi Chamber and a third in the Hill Antechamber cavity. The group of experts have now called for a deeper dig into the science behind the findings.
Published Template for success: Shaping hard carbon electrodes for next-generation batteries



Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers explored an innovative strategy to turn hard carbon into an excellent negative electrode material. Using inorganic zinc-based compounds as a template during synthesis, they prepared nanostructured hard carbon, which exhibits excellent performance in both alternative batteries.
Published Palaeo-CSI: Mosasaurs were picky eaters



Mosasaurs, those large marine reptiles from the long-gone Cretaceous world, were quite picky in their choice of diet. Researchers came to this conclusion after studying the wear marks on mosasaur teeth.
Published Understanding the dynamic behavior of rubber materials



Rubber-like materials can exhibit both spring-like and flow-like behaviors simultaneously, which contributes to their exceptional damping abilities. To understand the dynamic viscoelasticity of these materials, researchers have recently developed a novel system that can conduct dynamic mechanical analysis and dynamic micro X-ray computed tomography simultaneously. This technology can enhance our understanding of the microstructure of viscoelastic materials and pave the way for the development of better materials.
Published Head lice evolution mirrors human migration and colonization in the Americas



A new analysis of lice genetic diversity suggests that lice came to the Americas twice -- once during the first wave of human migration across the Bering Strait, and again during European colonization.
Published Scaling up nano for sustainable manufacturing



A research team has developed a high-performance coating material that self-assembles from 2D nanosheets, and which could significantly extend the shelf life of electronics, energy storage devices, health & safety products, and more. The researchers are the first to successfully scale up nanomaterial synthesis into useful materials for manufacturing and commercial applications.
Published 'Hot' new form of microscopy examines materials using evanescent waves



A team of researchers has built a prototype microscope that does not rely on backscattered radiation, instead uses passive detection of thermally excited evanescent waves. They have examined dielectric materials with passive near-field spectroscopy to develop a detection model to further refine the technique, working to develop a new kind of microscopy for examining nanoscopic material surfaces.
Published French love letters confiscated by Britain finally read after 265 years



Over 100 letters sent to French sailors by their fianc es, wives, parents and siblings -- but never delivered -- have been opened and studied for the first time since they were written in 1757-8.
Published 450-million-year-old organism finds new life in Softbotics



Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal



The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
Published Researchers discover new ultra strong material for microchip sensors



Researchers have unveiled a remarkable new material with potential to impact the world of material science: amorphous silicon carbide (a-SiC). Beyond its exceptional strength, this material demonstrates mechanical properties crucial for vibration isolation on a microchip. Amorphous silicon carbide is therefore particularly suitable for making ultra-sensitive microchip sensors.
Published Researchers engineer colloidal quasicrystals using DNA-modified building blocks



A new study unveils a novel methodology to engineer colloidal quasicrystals using DNA-modified building blocks. The implications of this breakthrough are far-reaching, offering a potential blueprint for the controlled synthesis of other complex structures previously considered beyond reach.
Published Hebrew prayer book fills gap in Italian earthquake history



The chance discovery of a note written in a 15th century Hebrew prayer book fills an important gap in the historical Italian earthquake record, offering a brief glimpse of a previously unknown earthquake affecting the Marche region in the central Apennines.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators



Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published Where is a sea star's head? Maybe just about everywhere



A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published New twist on optical tweezers



Optical tweezers use laser light to manipulate small particles. A new method has been advanced using Stampede2 supercomputer simulations that makes optical tweezers safer to use for potential biological applications, such as cancer therapy.
