  • To look through space is to look through time. Astronomers on a 5-years survey have turned up 100 supermassive black holes from a time when they were thought to be rare, suggesting we might need to rewrite our understanding of their evolution.
  • Science
    Some studies suggest the world is entering a sixth major extinction event. But now, in a rare piece of good news from that field, researchers from Australia, Canada and the US have rediscovered Wallace’s giant bee, an insect that hasn’t been seen in almost 40 years.

    According to a new study, Earth's surface is smooth compared to the landscapes found deep within the planet. Using data from one of the biggest earthquakes on record, geophysicists have now found massive mountain ranges hundreds of kilometers beneath our feet.
  • For such simple organisms, bacteria are surprisingly crafty when it comes to defending themselves from antibiotics. Now researchers at Princeton have discovered a new bacterial defense mechanism, where dying bugs will “hoard” antibiotics to allow their neighbors to grow unharmed.
  • Science
    ​Although traditional seismographs are essential for warning of earthquakes, they can be difficult to access when placed on the sea floor. Well, that's where the MERMAID underwater seismic floats are designed to come in, and they've recently been successfully tested in the Galápagos.
  • As the seas get warmer and more acidic, all kinds of havoc is wrought, and now a new study has identified yet another symptom. Researchers at Princeton and McGill Universities have found that the seafloor is beginning to dissolve as a result of human activity.

    ​Cloudina was a tiny sea creature that existed about 545 million years ago, and many scientists believe that it played a major role in building the first reefs. Princeton geoscientists Adam Maloof and Akshay Mehra, however, think otherwise – and they do so because of a unique rock-grinding machine.
  • ​When it comes to part-picking robots, they're typically programmed to grasp a specific object in a specific fashion. Scientists from MIT and Princeton, however, have developed a system that allows robots to grab random objects from a bin, then identify what the objects are and where they should go.
  • Scientists may eventually be able to biologically engineer unique artificial lifeforms from scratch. A new study from Princeton has brought that future a step closer, by confirming that an artificial protein the team developed functions as an enzyme in living bacteria.
  • There are stories in the stars, so they say, and the story of Kronos is a doozy. Astronomers from Princeton noticed some marked chemical differences between the star and its binary partner, Krios, and determined the most likely cause: Kronos has devoured the equivalent of 15 Earths.
  • Future windows could change their tint or opacity on demand to keep out unwanted heat, light or nosy neighbors. A team from Princeton has now developed a self-powered “smart window” system that uses a transparent solar cell to harvest UV energy from sunlight.
  • Science
    A new water purification technology developed by researchers at Princeton University doesn't require filters, instead relying on the injection of CO2 gas to change the water's​ chemistry and separate waste particles based on their electrical charge.
