Formation of the moon brought water to Earth

Earth seen from the moon (stock image; elements of this image are furnished by NASA). Credit: © Arvin / Adobe Stock The Earth is unique in our solar system: It is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Both were essential for…

Wealthy man looking down on city. Credit: © ChenPG / Adobe Stock People who see themselves as being in a higher social class may tend to have an exaggerated belief that they are more adept than their equally capable lower-class counterparts, and that overconfidence can often be misinterpreted by others as greater competence in important…

Synthetic biologists hack bacterial sensors

Bacteria illustrations (stock image). Credit: © pandawild / Adobe Stock Rice University synthetic biologists have hacked bacterial sensing with a plug-and-play system that could be used to mix-and-match tens of thousands of sensory inputs and genetic outputs. The technology has wide-ranging implications for medical diagnostics, the study of deadly pathogens, environmental monitoring and more. In…

Anxiety might be alleviated by regulating gut bacteria

Gut microbes illustration. Credit: © nobeastsofierce / Adobe Stock People who experience anxiety symptoms might be helped by taking steps to regulate the microorganisms in their gut using probiotic and non-probiotic food and supplements, suggests a review of studies published today in the journal General Psychiatry. Anxiety symptoms are common in people with mental diseases…

The return of the wolves

Howling wolves. Credit: © dine Haase / Adobe Stock The current return of wolves to human-dominated landscapes poses a major challenge for the protection of this species, says conservation biologist and private lecturer (PD) Dr. Marco Heurich from the University of Freiburg. He emphasizes that conflicts arise around the conservation of wolves in these landscapes…

Bonobo mothers help their sons to have more offspring

Bonobos. Credit: © IADNIKOV SERGEI / Adobe Stock In many social animal species individuals share child-rearing duties, but new research from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, finds that bonobo mothers go the extra step and actually take action to ensure their sons will become fathers. This way bonobo mothers increase…

New method to predict the vulnerability of ecosystems

Pouncing snow leopard. Credit: © Jane Rix 2018 / Adobe Stock Natural ecosystems are as vulnerable as they are diverse. Environmental changes such as climate change, pollution or the spread of alien species can easily throw an ecosystem off balance. Researchers are therefore investigating how susceptible ecosystems are to disruption. But in their search for…

Farmers have less leisure time than hunter-gatherers

Rice farm, Philippines (stock image). Credit: © raksyBH / Adobe Stock Hunter-gatherers in the Philippines who adopt farming work around ten hours a week longer than their forager neighbours, a new study suggests, complicating the idea that agriculture represents progress. The research also shows that a shift to agriculture impacts most on the lives of…

Dietary cholesterol or egg consumption do not increase the risk of stroke, Finnish study...

Soft-boiled egg. Credit: © aga7ta / Adobe Stock A new study from the University of Eastern Finland shows that a moderately high intake of dietary cholesterol or consumption of up to one egg per day is not associated with an elevated risk of stroke. Furthermore, no association was found in carriers of the APOE4 phenotype,…

Why are gels elastic?

Toothpaste on brush. Credit: © cristovao31 / Adobe Stock From the toothpaste you squeeze on your brush first thing in the morning to the yogurt you slurp down to the fabric softener that keeps your pajamas cozy and soft, gels are ubiquitous in consumer products, foods, and in industrial applications, too. However, until now, scientists…

Giant impact caused difference between Moon’s hemispheres

Moon. Credit: © astrosystem / Adobe Stock The stark difference between the Moon's heavily-cratered farside and the lower-lying open basins of the Earth-facing nearside has puzzled scientists for decades. Now, new evidence about the Moon's crust suggests the differences were caused by a wayward dwarf planet colliding with the Moon in the early history of…

A new way of diagnosing and treating disease — without cutting skin

Laser light (stock image). Credit: © ivanovevgeniy / Adobe Stock University of British Columbia researchers have developed a specialized microscope that has the potential ability to both diagnose diseases that include skin cancer and perform incredibly precise surgery -- all without cutting skin. The researchers describe the technology in a study published today in Science…

Driverless cars working together can speed up traffic by 35%

Autonomous cars concept. Credit: © folienfeuer / Adobe Stock A fleet of driverless cars working together to keep traffic moving smoothly can improve overall traffic flow by at least 35 percent, researchers have shown. The researchers, from the University of Cambridge, programmed a small fleet of miniature robotic cars to drive on a multi-lane track…

‘Spider-like senses’ could help autonomous machines see better

Drones in city concept (stock image). Credit: © ChenPG / Adobe Stock What if drones and self-driving cars had the tingling "spidey senses" of Spider-Man? They might actually detect and avoid objects better, says Andres Arrieta, an assistant professor of mechanical engineering at Purdue University, because they would process sensory information faster. Better sensing capabilities…

How egg cells choose their best powerhouses to pass on

Mitochondria illustration. Credit: © Mopic / Adobe Stock Developing egg cells conduct tests to select the healthiest of their energy-making machines to be passed to the next generation. A new study in fruit flies, published online May 15 in Nature, shows how the testing is done. The work focuses on mitochondria, the cellular machines that…

Scientists find new type of cell that helps tadpoles’ tails regenerate

Tadpole. Credit: © Frank / Adobe Stock Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These 'Regeneration-Organizing Cells' help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues. It…
