How to Distinguish Habitable Worlds Apart from Lifeless Gas Giants

Telling Habitable Worlds Apart from Lifeless Ones

A new study demonstrates how to distinguish between cloudy mini-Neptunes and volatile-dominated super-Earths based on the differences in the wing steepness and relative depths of water absorption features in moderate-resolution NIR transmission spectra (R~100). Perhaps the most intriguing exoplanets found so far are those bigger than our rocky, oceanic Earth but smaller than cold, gas-shrouded […]

Mitochondria Can Either Spur or Stop Obesity

Mitochondria Are the Key to Becoming Obese or Remaining Lean

In two newly published studies, researchers show how mitochondria play a key role in the body’s ability to control weight gain. Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body’s energy-producing “battery,” according to two new studies by Yale School of Medicine researchers featured as the cover story in […]

Observations Reveal How Interstellar Dust Grains Align

Astronomers Reveal Critical Interplay of Interstellar Dust and Hydrogen

In a newly published study, astronomers report key observations that confirm a theory on how dust grains in interstellar space spin and organize themselves in the presence of magnetic fields to precisely align in key astrophysical environments. For astrophysicists, the interplay of hydrogen — the most common molecule in the universe — and the vast […]

Harvard and MIT Scientists Create Never-Before-Seen Form of Matter

Scientists Create a New Form of Matter

By binding photons together to form molecules, scientists from Harvard and MIT have created a never-before-seen form of matter. Harvard and MIT scientists are challenging the conventional wisdom about light, and they didn’t need to go to a galaxy far, far away to do it. Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, […]

Ocean Eddies Are Mathematically Equivalent to Black Holes

Researchers Discover Mathematical Link between Ocean Eddies and Black Holes

According to newly published research, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly shielded by circular water paths that nothing can escape from the inside of these loops, not even water. The mild winters experienced in Northern Europe are thanks […]
