Ancient crocodiles' family tree reveals unexpected twists and turns

Despite 300 years of research, and a recent renaissance in the study of their biological make-up, the mysterious, marauding teleosauroids have remained enduringly elusive. Scientific understanding of this distant cousin of present day long snouted gharials has been hampered by a poor grasp of their evolutionary journey - until now.

Final dance of unequal black hole partners

Researchers used the Frontera supercomputer to model for the first time a black hole merger of two black holes with very different sizes (128:1). The research required seven months of constant computation. The results predict the gravitational waves such a merger would produce, as well as characteristics of the resulting merged black hole.

Baby dinosaurs were 'little adults'

Paleontologists have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed 'Fabian', was discovered in 2015 at the Frick fossil site in Switzerland.

Down Syndrome-associated gene suppresses age-related corneal clouding

Down syndrome and hypercholesterolemia mouse models suggest that the DSCR-1 gene protects against abnormal cornea vascularization and associated blindness by suppressing oxidized LDL cholesterol production and downstream angiogenic signaling during chronic high cholesterol. While the neurological pathology of Down syndrome patients worsens with age, they are less susceptible to age-related...

Higher-resolution imaging of living, moving cells using plasmonic metasurfaces

Researchers have demonstrated that placing cells on a plasmonic metasurface of self-assembled gold nanoparticle can improve the resolution of images of living cells taken in real-time under a widefield fluorescence microscope. The metasurface effectively confines light emission from parts of the cell near the metasurface to a nano-thickness plane, providing a simple method to improving both axial...

Has the hidden matter of the universe been discovered?

Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data.

A new candidate material for quantum spin liquids

Using a unique material, scientists have been able to design and study an unusual state of matter, the Quantum Spin Liquid. The work has significant implications for future technologies, from quantum computing to superconductivity and spintronics.

Patients reported international hydroxychloroquine shortages due to COVID-19

A new study shows that patients with rheumatic diseases across Africa, Southeast Asia, the Americas and Europe had trouble filling their prescriptions of antimalarial drugs, including hydroxychloroquine, during the 2020 global coronavirus pandemic, when antimalarials were touted as a possible COVID-19 treatment. Patients who could not access their antimalarial drugs faced worse physical and mental...
