Geologists challenge conventional view of Earth’s continental history, stability with new study
The seemingly stable regions of the Earth’s continental plates — the so-called stable cratons — have suffered repetitive deformation below their crust since their formation in the remote past, according to new research from the University of Illinois…
Researchers describe the melting of gold nanoparticles in gold-bearing fluids in the Earth’s crust
Gold is a precious metal that has always fascinated humans. From Priam’s Treasure to the legend of El Dorado, gold –regarded as the noblest of metals– has been a symbol of splendour and wealth in many civilizations. Historically, gold deposits were k…
Chronic exposure to lead, cadmium and arsenic increases risk of cardiovascular disease
Around the world, most people are regularly exposed to low or moderate levels of lead, cadmium and arsenic in the environment, increasing risk of coronary artery disease, stroke and peripheral artery disease, according to a new statement.
New study links contraceptive pills and depression
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women’s risk by 73 per cent during the first two years of use.
All-electric rideshare fleet could reduce carbon emissions, increase traffic issues
Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehic…
A novel, completely solid, rechargeable air battery
Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as fl…
Flaring star could be down to young planet’s disc inferno
New simulations offer new explanation for star’s 85-year flare. In this scenario, a young giant planet is burning up very close to its star, suggesting solar systems may have hosted many of such planets that have since ‘evaporated’.
Loneliness, insomnia linked to work with AI systems
Employees who frequently interact with artificial intelligence systems are more likely to experience loneliness that can lead to insomnia and increased after-work drinking, according to research published by the American Psychological Association.
Climate change: Rising rainfall, not temperatures, threaten giraffe survival
Giraffes in the East African savannahs are adapting surprisingly well to the rising temperatures caused by climate change. However, they are threatened by increasingly heavy rainfall, as researchers have shown.
A new Tatooine-like multi-planetary system identified
An international team of astronomers has announced the second-ever discovery of a multiplanetary circumbinary system.
New material transforms light, creating new possibilities for sensors
A new class of materials that can absorb low energy light and transform it into higher energy light might lead to more efficient solar panels, more accurate medical imaging and better night vision goggles.
Which came first: The reptile or the egg?
The earliest reptiles, birds and mammals may have borne live young, researchers have revealed.
