As the advent of quantum computers grows closer, cryptographers are trying to devise new mathematical schemes to secure data against their hypothetical attacks.
How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place for up to 30 months to laterally buttress the emerging permanent sabers. By the time the baby teeth fell out, presumably the adult cat knew how to protect its sabers during attacks.
Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
The first study of the use of microarray patches to vaccinate children has shown that the method is safe and induces strong immune responses. The phase 1/2 randomized trial compared results from the measles and rubella vaccine delivered by a microarray patch, a small sticking plaster-like device with an array of microscopic projections that painlessly penetrate the skin and deliver the vaccine, or by conventional injection with a needle and syringe.
The research explores how CRISPR can be used to edit RNA.
While mathematical analysis helps sharpen an algorithm for the election process, a physics perspective can help check if it is implemented fairly
A new study shows that school entry requirements are linked to an increase in human papillomavirus (HPV) vaccinations.
Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give machines ethereal fingers.
When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.
A bright yellow pigment favored a century ago by Impressionists such as Matisse and Van Gogh is losing its luster. Researchers have developed a laser imaging technique that can detect the first tiny signs of the pigment's breakdown before they're visible to the eye. The work could help art conservators take earlier steps to make the color last.
For most people, biting into a lemon would leave them puckered up and desperate to lose that sour flavor, but a new study revealed that roughly one in eight adults like intensely sour sensations. The cross-cultural study demonstrated there is a subset of 'sour likers' who enjoy exceptionally sour foods.
Researchers have discovered enzymes that remove hindrances that stood in the way of developing universal donor blood.
Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models.
Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria. This specificity is presumably mediated by a very special mechanism of action, which the researchers were able to decipher in detail.
Virtual reality dance made easier with crowd wave technique. Open source code can be downloaded for Quest 2 and 3.
Scientists say that an experimental monoclonal antibody drug called mAb43 appears to prevent and reverse the onset of clinical type 1 diabetes in mice, and in some cases, to lengthen the animals' lifespan.
Researchers tested a research-based intervention with English learners with math difficulty. The intervention proved to boost comprehension and help students synthesize and visualize information, which improved the students' math world problem-solving skills.
It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.
