Thanks in part to the popular film Finding Nemo, clownfishes are well known to the public and well represented in scientific literature. But the same can't be said for the equally colorful sea anemones — venomous, tentacled animals — that protect clownfishes and that the fish nourish and protect in return. A new study takes a step to change that, presenting a new tree of life for clownfish-hosti
On December 1, 1862—a month before he issued the Emancipation Proclamation—President Abraham Lincoln wrote to Congress. He was not yet the Great Emancipator. Instead, he proposed to become the Great Compensator. Lincoln proposed a Thirteenth Amendment to the U.S. Constitution: the most expansive and expensive slavery reparations plan ever put forth by a U.S. president. "Every State wherein slaver
The first time someone commented on what I was eating at work, I was a teenager at my first job, manning the front desk at the local courthouse's law library. On the way out one day, a regular visitors interrupted my fistful of cashews to tell me he loved watching me eat—I did it with such relish. Before I could locate a response, he had left. At 18, I was already well aware of the frequency with

A group of astronomers from University of California, Santa Barbara has discovered cool halo gas spinning in the same direction as galactic disks in typical star-forming galaxies.The researchers used W. M. Keck Observatory to obtain the first-ever direct observational evidence showing that corotating halo gas is not only possible, but common. Their findings suggest that the whirling gas halo will
Composed of massive filaments of galaxies separated by giant voids, the cosmic web is the name astronomers give to the structure of our universe. Why does our universe have this peculiar, web-like structure? The answer lies in processes that took place in the first few hundred thousands years after the Big Bang. None Looking up at the night sky, it seems as though the stars and galaxies are sprea
Yellow Submarine Boaty McBoatface is no longer just an internet sensation — it's also a valuable contributor to climate change research. In 2016, the Natural Environment Research Council asked internet users to name its new research ship . But when "Boaty McBoatface" won the poll, they decided the moniker would be better suited to one of the ship's bright yellow autonomous submarines. On Tuesday,
The unusual appearance of deep-sea fish like the oarfish or slender ribbonfish in Japanese shallow waters does not mean that an earthquake is about to occur, according to a new statistical analysis.
China is among the leaders in the rapidly advancing artificial intelligence field, and its broad range of cutting-edge research expertise is on display in this special issue on 'Artificial Intelligence in China' of Big Data.
New research by University of Wisconsin-Madison sociologist Nathan Seltzer identifies a link between the long-term decline in manufacturing jobs — accelerated during the Great Recession — and reduced fertility rates.
Contrary to current industry trends to develop more immersive virtual reality systems, a new study found that a more immersive environment or the presence of real-world distractions could have surprising effects on a participant's recall, description of the virtual encounter, and how positive they feel about the experience.
Stay chill wherever you go. (Depositphotos/) Just because it's hot out doesn't mean you have to chug down lukewarm beer, soda, or water. Grab a cooler that'll keep your ice frozen and drinks bone-chillingly cold until well after your "Billy Joel and other party jams" playlist has finished. But, coolers have their own specific strengths. Here are some ice chests to fit your particular temperature-
Bad News Earlier this month, researchers from Australia's Breakthrough National Centre for Climate Restoration published research containing a dire warning: reverse climate change or face the end of human civilization as we know it. Now, in an interview with GQ , researcher David Spratt specifically calls out political and economic leaders for turning a blind eye to the ongoing crises of global c
A new study asked hundreds of participants what advice they would give their younger selves if they could. The subject matter tended to cluster around familiar areas of regret. The test subjects reported that they did start following their own advice later in life, and that it changed them for the better. Everybody regrets something; it seems to be part of the human condition. Ideas and choices t
Research supported by the Accelerating Medicines Partnership (AMP) on Rheumatoid Arthritis and Systemic Lupus Erythematosus (RA/SLE) provides new insights into tissue damage for these autoimmune conditions. These discoveries set the stage for uncovering potential drug target candidates that could advance to experimental treatments. Results of the studies were published today (June 18, 2019) in thr

The unmanned aircraft known as drones, used by hobbyists, researchers and industry to take aerial images and perform other tasks, are growing ever more popular—and smaller. But that miniaturization, which has produced drones that fit in a person's palm, has started to bump into the laws of physics.
Monument Valley sits on the Utah-Arizona border, within the Navajo Nation reservation. The iconic sandstone buttes that dot the valley floor can mostly be accessed or viewed from Monument Valley Navajo Tribal Park, which—though instantly recognizable—has many fewer visitors annually than the nearby Grand Canyon. Gathered here, a collection of images of some of the many moods of the valley, from w
It sounds like an old-school vinyl record, but the distinctive crackle in the music streamed into Chris Holloway's laboratory is atomic in origin. The group at the National Institute for Standards and Technology, Boulder, Colorado, spent a long six years finding a way to directly measure electric fields using atoms, so who can blame them for then having a little fun with their new technology?
Feet from the raw bars and sherbet-colored condominiums of Florida's Cedar Key, researchers discovered a new species of egg-sucking sea slug, a rare outlier in a group famous for being ultra-vegetarians.
The first mission involving the autonomous submarine vehicle Autosub Long Range (better known as 'Boaty McBoatface') has for the first time shed light on a key process linking increasing Antarctic winds to rising sea temperatures. Data collected from the expedition will help climate scientists build more accurate predictions of the effects of climate change on rising sea levels.
Ring Wraith When stars are young, they're often surrounded by a ring of dust and gas known as a protoplanetary disk . Eventually, the material in this disk can clump together, forming everything from planets to asteroids. Now, an international team of researchers has found a young star with thin rings and gaps in the outer part of its protoplanetary disk, a region typically home to wide, smooth h

A new study shows that over the past 10,000 years, humanity has experienced a number of foundational transitions, or 'bottlenecks.' During these periods of transition, the advance or decline of societies was related to energy availability in the form of a benign climate and other factors.
For chemists attempting to create new nitrides in the laboratory, a recently published large stability map of the ternary nitrides will be a significantly valuable tool.
A robot. (Pixabay/) Wine growers have a neat, if unusual, trick for making more flavorful wine — don't water the vines. Let the vines go dry right before harvest, and they will yield smaller grapes with more skin and less juice. Smaller grapes produce wine with a deeper color and more complex flavor. Trinchero Family Estates in Napa Valley, California wanted to make sure it was watering its grape

Slow-growing ponderosa pines may have a better chance of surviving longer than fast-growing ones, especially as climate change increases the frequency and intensity of drought, according to new research from the University of Montana.
Transitions are a hallmark of life. When dormant plants flower in the spring or when a young adult strikes out on their own, there is a shift in control. Similarly, there is a transition during early development when an embryo undergoes biochemical changes, switching from being controlled by maternal molecules to being governed by its own genome. For the first time, a team from the Perelman School
