Bizarre Self-Mutilation in Mothers Linked to Cholesterol

Like many octopuses, the California two-spot octopus (Octopus bimaculoides) declines and dies shortly after breeding. Credit: Tom Kleindinst, Marine Biological Laboratory Changes in cholesterol production lead to a tragic octopus death spiral. New research finds remarkable parallels in steroid hormone biology across cephalopods, mice, and humans that can have dire consequences when disrupted. Despite their … Read more

Engineers Investigating NASA’s Voyager 1 Telemetry Data

The team will continue to monitor the signal closely as they continue to determine whether the invalid data is coming directly from the AACS or another system involved in producing and sending telemetry data. Until the nature of the issue is better understood, the team cannot anticipate whether this might affect how long the spacecraft … Read more

Astronomers study galactic nurseries with help of cosmic telescope

Cutting edge instruments and perfect cosmic alignments have allowed astronomers to peer into the nursery rooms of some of the oldest galaxies in the universe. A new paper published Thursday in the journal Nature describes how scientists used a technique called gravitational lensing and new spectrograph technology to view and characterize massive clouds of gas … Read more

Scientists discover why female octopuses self-mutilate to death after laying eggs

A drastic change in steroid hormone levels in female octopuses after they lay eggs causes them to mutilate themselves to death, a new study has revealed. Cephalopods, a group that includes octopuses and squids, have the largest central nervous systems and the greatest brain-to-body mass ratios among spineless creatures. However, cephalopods are unusually short-lived, unlike … Read more

First Direct Visual Evidence That the Object in the Center of the Milky Way Is Indeed a Black Hole

This is the first image of Sagittarius A* (Sgr A*), the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope (EHT). It is the first direct visual evidence of the presence of this black hole. Credit: EHT Collaboration Astronomers reveal the first image of the[{” attribute=””>black hole at the … Read more
