TESS Finds a Super-Earth and two Mini-Neptunes in a Single System

The field of extrasolar planet studies continues to grow by leaps and bounds. Currently, 5,090 exoplanets have been confirmed in 3,816 systems, and another 8,933 candidates are awaiting confirmation. The majority of these have been Neptune-like gas giants (1,779), gas giants comparable to Jupiter or Saturn (1,536), and rocky planets many times the size of … Read more

Early detection system for nuisance alga infesting Papahānaumokuākea reefs

New species of algae at Pearl and Hermes Atoll. Credit: NOAA/National Marine Sanctuaries A new species of nuisance algae, which was formally described in 2020 by University of Hawaiʻi at Mānoa experts, continues to smother more reefs and coral at Papahānaumokuākea Marine National Monument. However, an early detection technique developed by UH Mānoa researchers can … Read more

Scientists unveil new system for naming majority of the world’s microorganisms

Fluorescent-stained bacteria (pink) and archaea (green) from near-boiling water from Great Boiling Spring in Gerlach, Nevada. Credit: Jeremy Dodsworth What’s in a name? For microorganisms, apparently a lot. Prokaryotes are single-celled microorganisms—bacteria are an example—that are abundant the world over. They exist in the oceans, in soils, in extreme environments like hot springs, and even … Read more

Alien Artifacts Could Be Hidden Across the Solar System. Here’s how we Could Search for Them.

Do aliens exist? Almost certainly. The universe is vast and ancient, and our corner of it is not particularly special. If life emerged here, it probably did elsewhere. Keep in mind this is a super broad assumption. A single instance of fossilized archaebacteria-like organisms five superclusters away would be all it takes to say, “Yes, … Read more

A window into the fruit fly’s nervous system

An implanted Drosophila melanogaster fruit fly (foreground) interacting with an intact one (background). Credit: Alain Herzog (EPFL) Scientists at EPFL have developed an implantation technique that allows optical access to the “spinal cord” of the fruit fly, Drosophila melanogaster. This work can potentially lead to breakthroughs in the fields of neuroscience, artificial intelligence, and bio-inspired … Read more

Putting the food system in context

Credit: Sustainability (2022). DOI: 10.3390/su14137776 Innovations that make the food supply chain more “responsible”—eco-friendly, good for public health, fairer to farmers—will come faster if the contexts … Read more

Samples From Asteroid Ryugu Contain Bits That Came From Outside the Solar System

Long before our Sun began to form, stars were dying in our part of the galaxy. One of them exploded as a supernova. The catastrophe created minute grains of dust and the force of the explosion blasted through a nearby cloud of gas and dust. That action seeded the cloud with “alien” materials from the … Read more

How a scientist established a two-stage solar flare early warning system

Space: Science & Technology” width=”800″ height=”530″/> The visualization of four features during the existence of an active region. The x-axis represents time and its unit is a sample, where “0” represents the start time of an active region, and the time gap between adjacent times is 1.5 h. The y-axis represents the value of a … Read more

Scientists discover new antiviral defense system in bacteria

A team led by researchers at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has discovered that organisms across all three domains of life—bacteria, archaea, and eukaryotes (which includes plants and animals)—use pattern recognition of conserved viral proteins to defend against pathogens.
