Why shaving dulls even the sharpest of razors - Phys.org
Razors, scalpels, and knives are commonly made from stainless steel, honed to a razor-sharp edge and coated with even harder materials such as diamond-like carbon. However, knives require regular sharpening, while razors are routinely replaced after cutting m…

A 'Devonian' aquarium: Modern mutant fishes replicate creatures of ancient oceans - Phys.org
Zebrafish are a common aquarium species, of value to hobbyists and scientists alike. Researchers have now engineered an unusual change in them that has echoes of Jurassic Park—but looks alone are deceiving.

Surprisingly dense exoplanet challenges planet formation theories - Phys.org
New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet's ex…

Malignant cancer diagnosed in a dinosaur for the first time - Phys.org
A collaboration led by the Royal Ontario Museum (ROM) and McMaster University has led to the discovery and diagnosis of an aggressive malignant bone cancer—an osteosarcoma—for the first time ever in a dinosaur. No malignant cancers (tumours that can spread th…

Early Mars was covered in ice sheets, not flowing rivers: study - Phys.org
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively thro…

Satellite survey shows California's sinking coastal hotspots - Phys.org
A majority of the world population lives on low lying lands near the sea, some of which are predicted to submerge by the end of the 21st century due to rising sea levels.

New understanding of CRISPR-Cas9 tool could improve gene editing - Phys.org
Within a mere eight years, CRISPR-Cas9 has become the go-to genome editor for both basic research and gene therapy. But CRISPR-Cas9 also has spawned other potentially powerful DNA manipulation tools that could help fix genetic mutations responsible for heredi…

Astrophysicists observe long-theorized quantum phenomena - Phys.org
At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, they shrink in size, until they becom…

A plunge in incoming sunlight may have triggered 'Snowball Earths' - Phys.org
At least twice in Earth's history, nearly the entire planet was encased in a sheet of snow and ice. These dramatic "Snowball Earth" events occurred in quick succession, somewhere around 700 million years ago, and evidence suggests that the consecutive global …

Historic carbon dioxide decline could hold clues for future climate - Phys.org
A new study led by researchers at The Australian National University (ANU) provides a clearer snapshot of conditions during the last ice age—when global ice sheets were at their peak—and could even lead to better models for future climate projections.

Earliest humans stayed at the Americas 'oldest hotel' in Mexican cave - Phys.org
A cave in a remote part of Mexico was visited by humans around 30,000 years ago—15,000 years earlier than people were previously thought to have reached the Americas.
