Still searching for Planet 9
The solar system has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class that contains Eris, Sedna, Quaoar, Ceres and perhaps many more solar system small bodies. These are defined approximately as bodies that orb.....»»
High pond density benefits the dispersal of aquatic insects in urban areas
Urban ponds are paradise for aquatic life in the middle of the hustle and bustle of a city. In Finland, ponds are defined as freshwater bodies with diameter less than 200 meters, although there is no clear-cut distinction between the definition of po.....»»
Oversized and understudied: Researchers begin to uncover the mysterious lives of jumbo bacteriophages
Viruses are tiny but mighty intruders that can be found in the environment including in human bodies, and they can play a variety of roles in ecosystems. Viruses also come in a range of sizes. Some are even larger than bacteria, which scientists thou.....»»

"Turning Red" review: Imagine if Pixar made "Pen15"
Becoming a woman can be a messy process. For many, puberty hits hard, transforming our bodies into strange creatures we no longer recognize. Our limbs stretch; our curves swell. A natural musk blooms from our skin. We grow hair in places where there.....»»
After Mistaken Identity and Confusion, a Piece of Space Junk Slams Into the Moon
After years of zooming through deep space, a presumed leftover piece of a Chinese rocket slammed into the Moon today, just as space tracking experts expected it would. From a report: At least, it should have hit the Moon around 7:30AM ET this morning.....»»
RNA map of the mammalian cell nucleus reveals new insights into gene regulation
Most people are familiar with the cell nucleus from grade school biology as a storage compartment for DNA. But the nucleus also contains several distinct structures, called nuclear bodies or domains, whose roles scientists are just beginning to under.....»»
Looming Rocket Impact Forecasts Trouble for Future Lunar Exploration
Although the space-junk strike on March 4 will probably be harmless, such events may soon become more common—and dangerous -- Read more on ScientificAmerican.com.....»»
NASA"s plans to prevent a potential asteroid impact catastrophe explained
The Earth exists in a dangerous environment. Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet. Most of these are too small to pose a threat, but some can be cause for concern......»»

Colossal black holes locked in dance at heart of galaxy
Locked in an epic cosmic waltz 9 billion light years away, two supermassive black holes appear to be orbiting around each other every two years. The two giant bodies each have masses that are hundreds of millions of times larger than that of our sun,.....»»
Microscopic view on asteroid collisions could help us understand planet formation
A new way of dating collisions between asteroids and planetary bodies throughout our Solar System's history could help scientists reconstruct how and when planets were born......»»
New insights into the formation of brown dwarfs
Brown dwarfs are strange celestial bodies, occupying a kind of intermediate position between stars and planets. Astrophysicists sometimes call them "failed stars" because they have insufficient mass to burn hydrogen in their cores and shine like star.....»»
Public administration should consider effects of whiteness, masculinity and representation, researchers say
For most of the nation's history, white men have held the vast majority of U.S. government bureaucracy jobs. One recent way to address that has been representative bureaucracy, or ensuring governing bodies are made up of people who reflect their comm.....»»

Exploring Antarctica"s hidden under-ice rivers and their role in future sea-level rise
Underneath Antarctica's vast ice sheets there's a network of rivers and lakes. This is possible because of the insulating blanket of ice above, the flow of heat from within the Earth, and the small amount of heat generated as the ice deforms......»»
Planetary bodies observed for first time in habitable zone of dead star
A ring of planetary debris studded with moon-sized structures has been observed orbiting close to a white dwarf star, hinting at a nearby planet in the "habitable zone" where water and life could exist, according to a new study led by UCL researchers.....»»
Study in mice shows potential for gene-editing to tackle mitochondrial disorders
Defective mitochondria—the 'batteries' that power the cells of our bodies—could in future be repaired using gene-editing techniques. Scientists at the University of Cambridge have shown that it is possible to modify the mitochondrial genome in li.....»»
