Ink positive: how tattoos can heal the mind as well as adorn the body

Forget the stereotypes – getting inked can be a powerful means of reclaiming your body and processing grief or traumaIf one thing has become obvious in the summer heat and the inevitable baring of flesh, it’s the degree to which body art is now the norm. At the pool, the park, or the pub beer garden, you’ll find an enormous variety of designs inked on the skin representing the breadth of...

Boeing’s second Starliner mission to the ISS is a make-or-break moment

December 20, 2019, was supposed to be a landmark moment for the US space program and the US space industry, Boeing in particular. Boeing has been a partner of NASA since the agency’s inception in 1958—the company or those it acquired built the capsules that took Apollo astronauts to the moon and later built the space shuttle, and it helps operate the International Space Station. On that...

Sarah Perry: As an author, I felt useless in the pandemic. So I trained to be a vaccinator

Inspired by a desire to be good and help others during the pandemic, novelist Sarah Perry trained to vaccinate people. But what does it mean to be good when there is so much bad faith?Earlier this year – lockdown three: no sign of spring – I travelled to an airport to try to be good. Dogged for months by the sense of my own uselessness, and having wept with relief and accumulated sorrow when...

Image: Hubble spots squabbling galactic siblings

A dramatic triplet of galaxies takes center stage in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies. This system—known as Arp 195—is featured in the Atlas of Peculiar Galaxies, a list which showcases some of the weirder and more wonderful galaxies in the universe.

UN warns hunger is expected to rise in 23 global hotspots

Hunger is expected to rise in 23 global hotspots in the next three months with the highest alerts for "catastrophic" situations in Ethiopia's embattled Tigray region, southern Madagascar, Yemen, South Sudan and northern Nigeria, two U.N. agencies warned Friday.

Eutelsat Quantum: breakthrough reprogrammable satellite launches

Transmission beams can be reconfigured from the ground, whereas most commercial satellites are hard-wired before launchThe world’s first commercial fully reprogrammable satellite has been launched, ushering in a new era of more flexible communications.Unlike conventional models that are designed and “hard-wired” on Earth and cannot be repurposed once in orbit, the UK-engineered Eutelsat...

Covid clusters among the vaccinated are killing our back-to-normal dreams

They were gold miners in French Guiana, revelers in Cape Cod, and Indian health-care workers. Even though they inhabit worlds apart, they ended up having two things in common. All were vaccinated against covid-19. And they all became part of infection clusters. In recent weeks, cases like these are proving that covid-19 transmission chains and superspreading events can occur even in groups...

In the absence of genetic variation, asexual invasive species find new methods of adapting to their environment

Without the benefits of evolutionary genetic variation that accompany meiotic reproduction, how does an asexual invasive species adapt over time to a new environment to survive? In all-female weevil species that produce only female offspring from unfertilized eggs, the insects' survival techniques have led to the surprising discovery that these creatures can pass down gene regulation changes to...

Bird brains left other dinosaurs behind

Today, being "birdbrained" means forgetting where you left your keys or wallet. But 66 million years ago, it may have meant the difference between life and death—and may help explain why birds are the only dinosaurs left on Earth.

'Greening' biomaterials and scaffolds used in regenerative medicine

Green manufacturing is becoming an increasingly critical process across industries, propelled by a growing awareness of the negative environmental and health impacts associated with traditional practices. In the biomaterials industry, electrospinning is a universal fabrication method used around the world to produce nano- to microscale fibrous meshes that closely resemble native tissue...

Blood-sucking flies may be following chemicals produced by skin bacteria to locate bats to feed on

We humans aren't the only animals that have to worry about bug bites. There are thousands of insect species that have evolved to specialize in feeding on different mammals and birds, but scientists are still learning how these bugs differentiate between species to track down their preferred prey. It turns out, the attraction might not even be skin-deep: a new study in Molecular Ecology found...

Astronomers probe layer-cake structure of brown dwarf’s atmosphere

Astronomers have developed a new way to capture all the exquisite 'layer-cake' details of a brown dwarf's cloud structure. Because brown dwarfs are similar to super-Jupiters, this innovative technique can help deepen scientists' understanding of the atmospheres of giant alien worlds that are more massive than Jupiter.

The environment for permafrost in Daisetsu Mountains in Japan is projected to decrease significantly

Areas with climatic conditions suitable for sustaining permafrost in the Daisetsu Mountains are projected. The size of the area in the Daisetsu Mountains where climatic conditions were suitable for permafrost were estimated to be approximately 150 km2 in 2010. Under the business-as-usual scenario, this area is projected to disappear by around 2070. Under the low-carbon scenario consistent with...

'Greening' biomaterials and scaffolds used in regenerative medicine

In the biomaterials industry, electrospinning is a ubiquitous fabrication method used to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. Alas, the process has traditionally used solvents that not only are environmentally hazardous but also a significant barrier to industrial scale-up, clinical translation, and widespread use. But now, researchers report...

Can Australia fix its CovidSafe app and turn the pandemic into a ‘pingdemic’?

The Australian government is refusing to adopt technology used overseas that could speed up notification of close contactsThe federal government is in discussions to tweak its CovidSafe app to pick up more fleeting contacts due to the more infectious Delta variant, but is refusing to adopt technology used overseas that could speed up notification of close contacts.As England and Wales experience...

Source of DNA mutations in melanoma

The mutations that give rise to melanoma result from a chemical conversion in DNA fueled by sunlight -- not just a DNA copying error as previously believed, reports a new study. The findings upend long-held beliefs about the mechanisms underlying the disease, reinforce the importance of prevention efforts and offer a path forward for investigating the origins of other cancer types.

A single cell type map of human tissues

In a study published in the US journal Science Advances, a single cell type map of human tissues is presented. An open access atlas has been launched with more than 250,000 interactive plots to allow researchers to explore the expression in individual single cell types for all protein-coding genes in these tissues.
