Scientists find elusive gas hiding in plain sight

The discovery of turbulent, compact gas in otherwise dormant galaxies gives researchers one more clue to solving the mystery of how galaxies in particular live, evolve and die

Scientists discover that post-starburst galaxies condense their gas rather than expelling it, begging the question: what’s keeping them from forming stars? Post-starburst galaxies were previously thought to scatter all of their gas and dust—the fuel required for creating new stars—in violent energy bursts and at extraordinary speed. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) reveals that these galaxies don’t scatter all of their star-forming fuel. Instead, these dormant galaxies hold onto and compress large amounts of highly-concentrated, turbulent gas after their supposed end. But contrary to expectation, they’re not using it to form stars.

Hey DUDE: mysterious death of carbon star plays out like six-ring circus

V Hya is a carbon-rich asymptotic giant branch (AGB) star located approximately 1,300 light-years from Earth in the constellation Hydra

Scientists studying V Hydrae (V Hya) have witnessed the star’s mysterious death throes in unprecedented detail. Using the Atacama Large Millimeter/submillimeter Array (ALMA) and data from the Hubble Space Telescope (HST), the team discovered six slowly-expanding rings and two hourglass-shaped structures caused by the high-speed ejection of matter out into space. The results of the study are published in The Astrophysical Journal.

Facebook analysis to prevent epilepsy-related deaths

Emotion and stress cues hidden in posts might serve as early warnings of unexpected death

A group of researchers demonstrate that social media could be used to detect behaviors preceding Sudden Unexpected Death in Epilepsy (SUDEP), the leading cause of death in people with uncontrolled epileptic seizures. The findings published in Epilepsy & Behavior reveal that the activity of epilepsy patients in social media increased before their sudden death. These changes in digital behavior could be used as early-warning signals to put preventive interventions for SUDEP into practice, possibly avoiding death.

A decade of deep-reef exploration in the Greater Caribbean

The use of submersibles exponentially increased recorded diversity of islands’ deep-reef fish faunas

The mysteries of underwater life have long been a source of inspiration for writers, filmmakers, and marine biologists. But scientists interested in understanding the biological diversity of the oceans are often limited by the relatively shallow depths accessible via scuba diving. Small research submersibles, while expensive, allow for the exploration of much deeper waters. A new paper co-authored by researchers at the Smithsonian’s Tropical Research Institute (STRI) and National Museum of Natural History (NMNH), the University of Washington and the Universidad Nacional Autónoma de Honduras describes the important contribution of submersibles to increasing our knowledge about the diversity of deep-reef fishes in the Greater Caribbean.

Smelly ocelot habitats may scare off seed-dispersing rodents

An experiment in Panama’s Parque Natural Metropolitano and Gamboa revealed that agoutis were less likely to disperse and pilfer seeds in sites where ferocious felines roam

When going through stressful situations, some people lose their appetite. Similarly, animals that are scared for their lives tend to eat less. In nature, this behavioral change could have downstream effects. Dumas Galvez, a postdoctoral fellow at the Smithsonian Tropical Research Institute (STRI) wondered how fear of predation could influence the consumption patterns of important seed dispersers such as the Central American agouti, a rodent that loves munching on the seeds of Attalea butyracea, a tropical palm tree also known as corozo, palma real o palma de vino.

Tell me what you eat and I will tell you how your microbiota evolves

New study reveals how gut bacteria adapt and affect health in response to diet

New research reveals that diet can change the evolutionary path of bacteria in the gut, within host-relevant timescales. The study, published in Cell Host & Microbe, demonstrates how quickly Bacteroides thetaiotaomicron (B. theta), a prevalent bacterium in the human gut, acquires adaptive mutations in response to dietary changes. These findings show that acquisition of genetic changes can explain the observed microbiota-mediated negative effects that unbalanced diets have on host health.

Eyes in the Sky: drones help solve tropical tree mortality mysteries

Understanding when and where trees die in vast tropical forests is a challenging first step toward understanding carbon dynamics and climate change

Imagine trying to understand how climate change affects vast tropical forests by determining how many trees die each year. Clouds get in the way of satellite views and on-the-ground estimates are expensive and impractical in remote areas. But researchers at the Smithsonian Tropical Research Institute (STRI) are excited by a new analysis that explains variation in tree mortality based on drone images of 1500 hectares of the most-studied tropical forest, Barro Colorado Island, in Panama.

A genetic database to identify missing persons in El Salvador

The Central American country’s powerful database is essential to be able to identify victims and missing persons resulting from the civil war and also emigrants who lose their lives every year trying to cross the border between Mexico and the US

El Salvador, like other Central American countries, has suffered repression and human rights violations ever since colonial times. Indeed, social injustice in the country persisted and was a major trigger of the 1980-1992 armed conflict.

Fortuitous discovery: accidental tree wound reveals novel symbiotic behavior

One afternoon, during the early days of the COVID-19 pandemic in Panama, a bored teenager with a slingshot and a clay ball accidentally shot entry and exit holes in a Cecropia tree trunk. These are “ant-plant” trees, which famously cooperate with fierce Azteca ants; the trees provide shelter and food to the ants, and in exchange the ants defend their leaves against herbivores. The next morning, to his surprise, the Azteca alfari ants living within the Cecropia trunk had patched up the wound.

ALMA catches “intruder” redhanded in rarely detected stellar flyby event

While such intruder-based flyby events have previously been witnessed with some regularity in computer simulations of star formation, few convincing direct observations have ever been made

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder—not bound to the system—object came in close proximity to and interacted with the environment surrounding the binary protostar, causing the formation of chaotic, stretched-out streams of dust and gas in the disk surrounding it.
