Insects typically have a variety of complex exoskeleton structures, which support them in their movements and everyday activities. Fabricating artificial exoskeletons for insect-inspired robots that match the complexity of these naturally-occurring structures is a key challenge in the field of robotics.

Although researchers have proposed several fabrication processes and techniques to produce exoskeletons for insect-inspired robots, many of these methods are extremely complex or rely on expensive equipment and materials. This makes them unfeasible and difficult to apply on a wider scale.

With this in mind, researchers at the University of California in San Diego have recently developed a new process to design and fabricate components for insect-inspired robots with exoskeleton structures. They introduced this process, called flexoskeleton printing, in a paper prepublished on arXiv.

Anzalone’s prime editor is a little different. Its enzyme is actually two that have been fused together—a molecule that acts like a scalpel combined with something called a reverse transcriptase, which converts RNA into DNA. His RNA guide is a little different too: It not only finds the DNA in need of fixing, but also carries a copy of the edit to be made. When it locates its target DNA, it makes a little nick, and the reverse transcriptase starts adding the corrected sequence of DNA letter by letter, like the strikers on a typewriter.

A less error-prone DNA editing method could correct many more harmful mutations than was previously possible.

We’ve long known that viruses can target cancers in our bodies. Now, thanks to gene editing, we’re using them as tumour search and destroy agents – and getting our immune systems to join the fight too.

It has long been understood, and by cultures too various to list, that salamanders have something of the supernatural about them. Their name is thought to derive from an ancient Persian vocable meaning ‘fire within’, and for at least 2,000 years they were believed to be impervious to flames, or even capable of extinguishing them on contact. Aristotle recorded this exceptional characteristic, as did Leonardo da Vinci. The Talmud advises that smearing salamander blood on your skin will confer inflammability. Not so. But the intuition that salamanders possess fantastical powers is not unfounded.

Like earthbound immortals, salamanders regenerate. If you cut off a salamander’s tail, or its arm, or its leg, or portions of any of these, it will not form a stump or a scar but will instead replace the lost appendage with a perfect new one, an intricacy of muscle, nerve, bone and the rest. It will sprout like a sapling. Science has been chopping up salamanders for more than 200 years with the aim of simply understanding the mechanics of their marvels, but more recently with the additional aim of someday replicating those marvels in ourselves. Might salamanders be the great hope of regenerative medicine?

The salamander in which regeneration is most often studied is an odd and endearingly unattractive Mexican species known as the axolotl. In addition to its limbs and extremities, the axolotl is known to regrow its lower jaw, its retinae, ovaries, kidneys, heart, rudimentary lungs, spinal cord, and large chunks of its brain. It heals all sorts of wounds without scarring. The axolotl also integrates the body parts of its fellows as if they were its own, without the usual immune response, and this peculiar trait has facilitated some of the more grotesque disfigurements it’s endured in the name of science. In experiments after the Second World War, East German scientists grafted small axolotls crosswise through the backs of larger ones. The animals’ circulatory systems came to be linked, and the researchers hailed the conjoined mutants as triumphs of collectivism.

Lo sviluppo di biorobot autonomi compie un passo avanti grazie allo sviluppo di dispositivi robotici morbidi guidati dal tessuto neuromuscolare. Creati da un gruppo di ricerca dell’ Università dell’Illinois con a capo il professore di ingegneria meccanica e scienze meccaniche Taher Saif e il professore di bioingegneria Rashid Bashir, sono i primi biorobot semiautomatici capaci di muoversi autonomamente.

Regular fasting is associated with lower rates of heart failure and a longer life span, according to two new studies.

Researchers sought to shed new light on the centuries-old debate about how fasting affects health. Recent studies have shown it contributes to reductions in blood pressure, “bad” LDL cholesterol and insulin resistance, a condition that can raise blood sugar. A 2017 study showed alternate-day fasting was as effective as daily calorie restriction for losing weight and keeping the pounds off.

The new studies focused on data from patients evaluated for heart disease in Utah and other Rocky Mountain states. The research included hundreds of members of The Church of Jesus Christ of Latter-day Saints, also known as Mormons, who typically fast one Sunday each month, for up to 24 hours.

Boosting brain function is key to staving off the effects of aging. And if there was one thing every person should consider doing right now to keep their brain young, it is to add extra virgin olive oil (EVOO) to their diet, according to research by scientists at the Lewis Katz School of Medicine at Temple University (LKSOM). EVOO is a superfood, rich in cell-protecting antioxidants and known for its multiple health benefits, including helping put the brakes on diseases linked to aging, most notably cardiovascular disease. Previous LKSOM research on mice also showed that EVOO preserves memory and protects the brain against Alzheimer’s disease.

In a new study in mice published online in the journal Aging Cell, LKSOM scientists show that yet another group of aging-related diseases can be added to that list—tauopathies, which are characterized by the gradual buildup of an abnormal form of a protein called tau in the brain. This process leads to a decline in mental function, or dementia. The findings are the first to suggest that EVOO can defend against a specific type of mental decline linked to tauopathy known as frontotemporal dementia.

Alzheimer’s disease is itself one form of dementia. It primarily affects the hippocampus—the memory storage center in the brain. Frontotemporal dementia affects the areas of the brain near the forehead and ears. Symptoms typically emerge between ages 40 and 65 and include changes in personality and behavior, difficulties with language and writing, and eventual deterioration of memory and ability to learn from prior experience.

According to the World Health Organization, CBD “is generally well-tolerated with a good safety profile,” but it’s not for everyone. CBD or cannabis-derived medicines can have contraindications with other drugs and can have side effects. A 2017 review of CBD studies said the most commonly reported are fatigue, diarrhea, and appetite or weight changes.

CBD is often touted as a cure-all, but that’s not the whole story. Learn everything you need to know about how CBD works—and how it doesn’t—here.
