Oh hey, not a big deal, but the hubble took a picture of a star that’s nearing supernova status
From an excellent post by Jason Davis
From Washington, D.C., the rings would only fill a portion of the sky, but appear striking nonetheless. Here, we see them at sunrise.
From Guatemala, only 14 degrees above the equator, the rings would begin to stretch across the horizon. Their reflected light would make the moon much brighter.
From Earth’s equator, Saturn’s rings would be viewed edge-on, appearing as a thin, bright line bisecting the sky.
At the March and September equinoxes, the Sun would be positioned directly over the rings, casting a dramatic shadow at the equator.
At midnight at the Tropic of Capricorn, which sits at 23 degrees south latitude, the Earth casts a shadow over the middle of the rings, while the outer portions remain lit.

Genetically modified organisms get a bad rap for many reasons, but we’ve actually been genetically altering what we eat since the dawn of human history.
“For 10,000 years, we have altered the genetic makeup of our crops,”explains UC Davis plant pathology professor Pamela Ronald.
“Today virtually everything we eat is produced from seeds that we have genetically altered in one way or another.” (You can read more about Ronald’s thoughts on genetically engineered food here.)
Right now her focus is on rice. It’s one of our basic crops and without it, we would struggle to feed much of the world.
With climate change, we’re seeing an increase in flooding in places like India and Bangladesh, which makes it harder to grow this important food staple.
So Ronald and her lab have developed a flood-tolerant strain of rice. It’s known as Sub1a or “scuba rice” and millions of farmers in South Asia are now growing it in their fields.
Today is National Food Day, a day dedicated to hunger awareness. But as we focus on food insecurity, we need to talk more about how global warming will make the problem worse.
As our climate continues to heat up, it has huge impacts on what foods we are able to grow. Will our crops be able to survive droughts and floods? The University of California leads six labs that are working to develop other climate-resilient crops including chickpea, cowpea and millet.

English-speaking parents tend to use vague, one-size-fits-all verbs as they emphasize nouns: cars, trucks, buses, bicycles and scooters all simply “go.” Mandarin speakers do the opposite: they use catchall nouns such as “vehicle” but describe action—driving, riding, sitting on, pushing—with very specific verbs. “As a native English speaker, my first instinct when a baby points is to label,” Tardif says. Her babysitter, on the other hand, was a native Mandarin speaker, whose instinct was to name the action she thought the child was trying to achieve.

The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were discovered more than a decade ago. Molecules trace the coldest parts of space, and black holes are the most energetic phenomena in the universe, so finding molecules in black hole winds was like discovering ice in a furnace.
Astronomers questioned how anything could survive the heat of the energetic outflows, but a new theory from researchers in Northwestern University’s Center for Interdisciplinary Research and Exploration in Astrophysics (CIERA) predicts that these molecules are not survivors at all, but brand-new molecules, born in the winds with unique properties that enable them to adapt to and thrive in the hostile environment.
