Are we missing a crucial component of sea-level rise?

Recent efforts using computational modeling to understand how melting ice in Antarctica will impact the planet's oceans have focused on ice-sheet geometry, fracture, and surface melting—processes that could potentially trigger or accelerate ice-sheet mass loss. Now, researchers from Stanford University have identified an additional process that could have a similarly significant effect on the ice sheet's future: thawing of the bed, known as basal thaw, at the interface of the land and the miles-thick ice sheet above it.

Webb telescope captures 'breathtaking' images of Orion Nebula

The wall of dense gas and dust resembles a massive winged creature, its glowing maw lit by a bright star as it soars through cosmic filaments.

'Dinosaur mummy': Researchers believe they've found one of the best preserved dinosaurs ever

Researchers in Canada have discovered parts of what they believe to be a full "dinosaur mummy" lodged in a hillside, the University of Reading in the United Kingdom announced last week.

New phases of water detected

Scientists at the University of Cambridge have discovered that water in a one-molecule layer acts like neither a liquid nor a solid, and that it becomes highly conductive at high pressures.

Conversion to LED lighting brings new kind of light pollution to Europe

A team of researchers at the University of Exeter has found that the slow conversion of outdoor lighting to LEDs across much of Europe has led to the development of a new kind of light pollution. In their paper published in the journal Science Advances, the group describes their study of photographs taken from the International Space Station.

380-million-year-old heart illuminates evolutionary history

Researchers have discovered a 380-million-year-old heart—the oldest ever found—alongside a separate fossilized stomach, intestine and liver in an ancient jawed fish, shedding new light on the evolution of our own bodies.

Can we live longer? Physicist makes discovery about telomeres

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery will help us understand aging and disease.

Mysterious diamonds came from outer space, scientists say

Strange diamonds from an ancient dwarf planet in our solar system may have formed shortly after the dwarf planet collided with a large asteroid about 4.5 billion years ago, according to scientists.

Refreezing Earth's poles feasible and cheap, new study finds

The poles are warming several times faster than the global average, causing record smashing heatwaves that were reported earlier this year in both the Arctic and Antarctic. Melting ice and collapsing glaciers at high latitudes would accelerate sea level rise around the planet. Fortunately, refreezing the poles by reducing incoming sunlight would be both feasible and remarkably cheap, according to new research published today in Environmental Research Communications.

New study of the Gough map shows what might be the lost islands of Welsh folklore

A pair of researchers, one with Swansea University, the other with Oxford University, has taken a new look at the Gough map and have found what might be the lost islands of ancient Welsh folklore. In their paper published in the journal Atlantic Geoscience, Simon Haslett and Davis Willis describe two small islands on the map that do not exist today.
