The mind-bending maths that could stop ‘quantum hackers’

The Hindu:Science - 30/04/2024
As the advent of quantum computers grows closer, cryptographers are trying to devise new mathematical schemes to secure data against their hypothetical attacks.

The double-fanged adolescence of saber-toothed cats

Science Daily - 30/04/2024
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.

Fading lights: Multiple threats to North America's firefly populations

Science Daily - 30/04/2024
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.

Microarray patches safe and effective for vaccinating children, trial suggests

Science Daily - 30/04/2024
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.

Research on RNA editing illuminates possible lifesaving treatments for genetic diseases

Science Daily - 30/04/2024
The research explores how CRISPR can be used to edit RNA.

The physics and maths of keeping elections fair and representative | Explained

The Hindu:Science - 30/04/2024
While mathematical analysis helps sharpen an algorithm for the election process, a physics perspective can help check if it is implemented fairly

Study finds school entry requirements linked to increased HPV vaccination rates

Science Daily - 30/04/2024
A new study shows that school entry requirements are linked to an increase in human papillomavirus (HPV) vaccinations.

Scientists harness the wind as a tool to move objects

Science Daily - 30/04/2024
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.

Long snouts protect foxes when diving headfirst in snow

Science Daily - 30/04/2024
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.

Laser imaging could offer early detection for at-risk artwork

Science Daily - 30/04/2024
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.

One in eight grown-ups love extreme tartness

Science Daily - 30/04/2024
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.

Enzymes open new path to universal donor blood

Science Daily - 29/04/2024
Researchers have discovered enzymes that remove hindrances that stood in the way of developing universal donor blood.

Gemini south reveals origin of unexpected differences in giant binary stars

Science Daily - 29/04/2024
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.

Possible alternative to antibiotics produced by bacteria

Science Daily - 29/04/2024
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.

Researchers develop a new way to instruct dance in Virtual Reality

Science Daily - 29/04/2024
Virtual reality dance made easier with crowd wave technique. Open source code can be downloaded for Quest 2 and 3.

Experimental type 1 diabetes drug shelters pancreas cells from immune system attack

Science Daily - 29/04/2024
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.

Intervention based on science of reading, math boosts comprehension, word problem-solving skills

Science Daily - 29/04/2024
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.

More plants on the menu of ancient hunter-gatherers

Science Daily - 29/04/2024
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.
