Spacey ‘super puffs’ are changing our understanding of how planets form

An artistic rendering of WASP-107b orbiting in front of its star (ESA/Hubble, NASA, M. Kornmesser/) When Caroline Piaulet first started looking at an exoplanet called WASP-107b, a gas giant orbiting a star in the Virgo constellation about 212 light years away, she was mostly interested in finding out what was inside it. “I essentially wanted […]

Changing resilience of oceans to climate change — ScienceDaily

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and present — depletes ocean oxygen, […]

Changing diets — not less physical activity — may best explain childhood obesity crisis

A third of rivers in US found to be changing from blue to green and yellow

Credit: Unsplash/CC0 Public Domain A team of researchers with members from the University of North Carolina at Chapel Hill and Colorado State University reports that approximately a third of the rivers in the U.S. have changed color over the past 34 years. In their paper published in the journal Geophysical Research Letters, the group describes […]

US rivers are changing from blue to yellow and green, satellite images show

  A third of U.S. rivers have significantly changed color over the last 36 years, turning from blue to  yellow and green, striking new images reveal. Researchers analyzed 235,000 satellite images — taken over a 34-year period between 1984 and 2018 — from NASA and the U.S. Geological Survey (USGS) Landsat program. The changing hues […]

What pandemic messaging around changing holiday rituals gets wrong

In the midst of the raging coronavirus pandemic, we’re faced with agonizing decisions about whether to forgo treasured holiday rituals. Many people have defied health officials, putting themselves at risk of contracting COVID-19 or spreading the disease in order to uphold their family traditions in person. A new paper by two researchers at UC Berkeley’s […]

Changing the perspective on the ‘Cinderella of the cytoskeleton’

SETD2 is a protein well known as a chromatin remodeler, one that helps turn genes on or off by modifying histone proteins in the nucleus of the cell. When researchers discovered that SETD2 is mutated or lost in several cancer types, most commonly a type of kidney cancer called clear-cell renal cell carcinoma, all eyes […]
