Longer, Refined Super Predator: A study to draw more accurate pictures of the true form of Megalodon
Shark biologists say such lemon sharks are a better model of the body of megalodon, which has become extinct than the Great White shark. Credit: Albert Kok Megalodon has long been imagined as a giant great white shark, but new research suggests that all perceptions are wrong. This study shows that prehistoric hunters had longer bodies, even lemon sharks and…

Water is older than we originally thought and may form an important component of the first galaxy
Primitive halo steam. A, B, simulated images at 1 kpc water vapor distance at 13M⊙CC supernova at 90 Myr after the explosion (a) and 200m⊙pi supernova at 3 Myr after the explosion (b). The mass fraction of halo’s diffuse water vapor differs from 10-14 to 10-12 for CC supernova and from 10-12 to 10-10 for PI supernova. The dense mass…

Graphyne’s transformation: a new carbon form with the potential of electronic devices
Orthogonal to sheet plane views of stacked arrangements of graphine AA, AB1, AB2, and ABC. Only the AA and AB1 packing modes are consistent with the interplanar reaction of triple bonds forming polycetylene chains in the reacted graphine. Credit: Proceedings of the National Academy of Sciences (2025). doi:10.1073/pnas.2413194122 Graphine is a different carbon crystalline form than both diamond and graphite.…

Structured light self-image in cylindrical systems reveals a new form of space-time duality
Illustrations of generalized self-images at angle positions and illustrations of angular angular momentum of related orbital angular momentum using ring-shaped optical fibers and phase masks. Credit: Matthias Erickson, University of Tampere Photonics researchers at the University of Tampere in Finland and the Kathler Brossel Institute in France have shown that self-image of light, a phenomenon known in nearly two centuries,…

Gibellulula ATTENBOROUGHII, a new fungus of an orb woven cave spider. Credit: Mold This week, astronomers reported the discovery of the super Earth, which could maintain life, and occupied the eccentric track around the stars inside and outside the resident zone. The first mouse, designed with embryon stem cells from two father, lived in adulthood. The researchers harmonized the morphological…

The bacteria in the polymer form cable-like structures and grow into a living gel.
A 3D rendering taken with a confocal microscope shows non-motile E. coli bacterial cells developing serpentine “cables” as they grow in a polymer solution. A scale bar is included. Credit: Sebastian Gonzalez La Corte et al./Princeton University/California Institute of Technology Scientists at the California Institute of Technology and Princeton University have found that bacterial cells growing in a slime-like polymer…

Planets can form even in the harshest conditions
An artist’s concept of planet formation occurring in a harsh stellar environment. Credit: AUI/NSF NRAO/S.Dagnello According to the most widely held astronomical model (the nebular hypothesis), new stars are born from giant clouds of dust and gas (also known as nebulae) that undergo gravitational collapse. The remaining dust and gas forms a protoplanetary disk surrounding the new star and slowly…

Team develops promising new form of antibiotic that causes bacterial cells to self-destruct
Credit: Journal of Medicinal Chemistry (2024). DOI: 10.1021/acs.jmedchem.4c00773 To address the global threat of antibiotic resistance, scientists are exploring new ways to bypass bacterial cell defense systems. Researchers at the University of Toronto (U of T) have used what they learned from previous research on cancer to develop a new compound that causes bacterial cells to self-destruct. The research team’s…

Rain helped form the first cells and may have been the beginning of life as we know it
Credit: Pixabay/CC0 Public Domain Billions of years of evolution have made modern cells incredibly complex. Inside cells, there are small compartments called organelles that perform specific functions essential for cell survival and activity. For example, the nucleus stores genetic material and mitochondria produce energy. Another important part of the cell is the membrane that surrounds it. Proteins embedded in the…
