Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it at hundreds of miles per second, creating bright shock waves. In this image, blue indicates ionized oxygen (O II) and purple shows ionized magnesium (Mg II). Researchers were particularly interested in these elements because they can be used to identify shocks and ionization fronts. This object is located in the nebula NGC 1977, which itself is part of a complex of three nebulae called The Running Man. NGC 1977 -- like its companions NGC 1975 and NGC 1973 -- is a reflection nebula, which means that it doesn't emit light on its own, but reflects light from nearby stars, like a streetlight illuminating fog. Hubble observed this region to look for stellar jets and planet-forming disks around young stars, and examine how their environment affects the evolution of such disks.

Exotic laser-produced high-energy-density (HED) plasmas akin to those found in stars and nuclear explosions could provide insight into events throughout the universe. Physicists have discovered a new way to measure and understand these plasmas, among the most extreme states of matter ever produced on Earth. Improved understanding could provide benefits ranging from fine-tuning the high-density plasmas in inertial confinement fusion experiments to better understanding of processes throughout the universe.

A team of researchers has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxin, to grow. Until now, they didn't understand exactly how auxin sets growth in motion.

In the human brain, the hormone insulin also acts on the most important neurotransmitter for the reward system, dopamine. Insulin lowers the dopamine level in a specific region of the brain (striatum) that regulates reward processes and cognitive functions, among other things. This interaction can be an important driver of the brain's regulation of glucose metabolism and eating behavior.

After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean. A new data-model study now shows that it took only a decade to initiate this tipping point in the climate system, and that ice mass loss then continued for many centuries.

Rising oceans get more attention in climate change discussions, but rivers are rising, too, according to new research by a University of South Carolina postdoctoral fellow. The research shows that rivers need more attention in policy management and disaster preparation, both at the coast and farther inland.

The World Climate Conference in Glasgow has just ended, and the question is whether the goal of maximum global heating of 1.5°C can still be achieved. In a model calculation, researchers show how the energy transition could lead to the lowest possible cumulative emissions: Instead of slowly cutting back emissions, we should quickly push ahead with the conversion to solar energy and use fossil power plants at full capacity for one last time to do so.

Galápagos giant tortoises can weigh well over 300 pounds and often live over 100 years. So what's the secret to their evolutionary success? A new study concludes that compared with other turtles, these animals evolved to have extra copies of genes -- called duplications -- that may protect against the ravages of aging, including cancer. Laboratory tests on Galápagos giant tortoise cells corroborate the idea that the animals have developed such defenses.

Bubbles are common in nature and can form when ocean waves break and when raindrops impact surfaces. When bubbles burst, they send tiny jets of water and other materials into the air. A new study examines how the interplay between bubble surfaces and water that contains organic materials contributes to the transport of aerosolized organic materials -- some of which are linked to the spread of disease or contamination -- into the atmosphere.

Maya archaeologists have excavated salt kitchens where brine was boiled in clay pots over fires in pole and thatch buildings preserved in oxygen-free sediment below the sea floor in Belize. But where these salt workers lived has been elusive, leaving possible interpretations of daily or seasonal workers from the coast or even inland. This gap left nagging questions about the organization of production and distribution.

By adding the genes necessary for transcription and translation to the artificial genomic DNA, it could be possible to develop artificial cells that can grow autonomously, and it will be expected to produce efficient useful substances.

Fear is essential for survival, but must be well regulated to avoid harmful behaviors such as panic attacks or exaggerated risk taking. Scientists have now demonstrated in mice that the brain relies on the body's feedback to regulate fear. The brain's insular cortex strongly reacts to stimuli signaling danger. However, when the body freezes in response to fear, the heartbeat slows down leading to attenuated insular cortex activity. Processing these opposing signals helps the insular cortex to keep fear in balance. The body's reactions are thus actively used to regulate emotions and are much more than passive emotional responses.

Groundwater in California's Central Valley is at risk of being depleted by pumping too much water during and after droughts. Under a best-case scenario, the researchers found there is a high probability it would take six to eight years to fully recover overdrafted water, but current California climate projections suggest realistic recovery times are even longer.
