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...
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...
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...
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.
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.

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...
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...

FRIDAY 30. JULY 2021
The world's first commercial fully re-programmable satellite lifted off from French Guiana on Friday on board an Ariane 5 rocket, ushering in a new era of more flexible communications.
A British court on Friday overturned government approval for the construction of a controversial road tunnel close to the Stonehenge stone circle, following opposition from historians, archaeologists and druids.
NASA did not violate regulations when it decided to give SpaceX the sole contract to build a Moon lander, a watchdog said Friday, in a ruling that denied challenges by competitors Blue Origin and Dynetics.
California's largest wildfire so far this year was flaring up Friday but it was because the flames were chewing through unburned islands of vegetation within a perimeter that firefighters have built, authorities said.
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...
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.
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...
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...
New research has found that two types of weevils, common yet invasive beetles in many parts of the world, have been using epigenetic changes to adapt and respond to different toxins in the plants they eat. The findings have implications for how we consider asexual invaders and how successful they can be because of gene regulation.
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.
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...
Researchers have shown that a targeted therapy using non-thermal radio waves is safe to use in the treatment of hepatocellular carcinoma (HCC), the most common type of liver cancer, according to a new study. The therapy also showed a benefit in overall survival.
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...
Symptoms for early COVID-19 infection differ among age groups and between men and women, new research has found.
Research on a newly discovered bird fossil found that a unique brain shape may be why the ancestors of living birds survived the mass extinction that claimed all other known dinosaurs.
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...
Occurring faster than the speed of sound, the mystery behind the breakdown of plasma discharges in water is one step closer to being understood as researchers pursue applying new diagnostic processes using state-of-the-art X-ray imaging to the challenging subject.
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.

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.
Greek authorities ordered additional fire patrols and infrastructure maintenance inspections Friday as the country grappled with a heat wave fed by hot air from Africa that is expected to last more than a week.
