Forming the Smallest Ice Crystals in the World

water-crystallises-with-a-six-fold-symmetry

A team of scientists have solved a previously unsolved scientific mystery, finding the minimum number of water molecules that must come together in order for them to be able to form a real ice crystal. Ice crystals also have small beginnings – even smaller than previously believed. Already 475 water molecules can form a real […]

Vampyroteuthis infernalis, the vampire squid, which technically isn’t a squid at all, is a cephalopod that lives 3,000 feet deep in warm waters. In the deep pelagic zone, there is little oxygen and V. infernalis reaches a size of just 30 cm in adulthood. V. infernalis feeds on corpses, feces and its own mucus and […]

Study Suggests that Astrocytes are Critically Important for Processing Sensory Information

astrocyte cells help the brain respond to visual stimuli

A newly published study from a team of neuroscientists at MIT is latest in a growing body of evidence suggesting that astrocytes are critically important for processing sensory information. A new study from MIT neuroscientists sheds light on a neural circuit that makes us likelier to remember what we’re seeing when our brains are in […]

Bearing a Male Child Can Alter a Woman’s Brain

male-cell-female-liver-tissue

A new study indicates that male DNA, left over from pregnancy with a male fetus, can persist in a woman’s brain throughout the rest of her life. Although the exact biological impact of the DNA is yet unclear, the study found that women with more male DNA in their brains were less likely to suffer […]

Troughs Suggest Vesta has Characteristics like a Planet or Large Moon

extensive system of troughs encircles Vesta's equatorial region

Using data from NASA’s Dawn spacecraft, scientists have been working hard to determine the story behind the enormous troughs that wrap around the giant asteroid Vesta and now believe that troughs may be dropped blocks of terrain bounded by fault lines. Washington — Enormous troughs that reach across the asteroid Vesta may actually be stretch […]

Mira Supercomputer Will Run Simulation of Our Universe

The advent of the Mira supercomputer, along with more powerful Sequoia and K supercomputers, marks the first time that computers have enough computational power to simulate trillions of particles on the move, running a simulation of the Universe. Mira can process quadrillions of operations every second, which is rare in the machine world. It will […]

3D Renderings of Carboniferous Period Insects

roachoid-insect-carboniferous

Two 305-million-year-old insect nymphs were scanned in high resolution in order to construct three-dimensional portraits. The two insects were scanned using fossils from the Carboniferous Period, which lasted from 359.2 Ma (million years ago) to the beginning of the Permian Period, at 299 Ma. The researchers published their findings in the journal PLoS ONE. One […]

Inhibition of MicroRNAs in Mice Can Attenuate Cardiovascular Stress

hypertrophic-cardiomyopathy

Cardiac stress that’s caused by a heart attack or high blood pressure will frequently lead to pathological heart growth and eventually lead to heart failure. Researchers have discovered that two micro-scale RNA molecules, microRNA miR-212 and miR-132 play a role in this detrimental development in mice. When these molecules were inhibited, the mice were protected […]

Genetic Variability Helps Sea Urchins Cope with Environmental Changes

strongylocentrotus-purpuratus

The current rising acidity in the ocean is supposed to have dire consequences for organisms like coral, but there are some sea urchins that have the genetic tools to adapt to inhospitable conditions. The results were presented at the Third International Symposium on the Ocean in a High CO2 World in Monterey, California, and are […]

New Image of the Seagull Nebula

Close-up view of the head of the Seagull Nebula

A close-up view of the head of the Seagull Nebula, which is located roughly 3,700 light-years away from Earth, was captured in this new image from ESO’s La Silla Observatory. Nebulae are among the most visually impressive objects in the night sky. They are interstellar clouds of dust, molecules, hydrogen, helium and other ionized gases […]
