Oxygen in the atmosphere may not be an entirely reliable ‘biosignature,’ but there are ways to distinguish false positives from signs of life, scientists say….
A new study published in Elementa by researchers at the University of California, Santa Cruz and NOAA examines traditional aspects of seafood sustainability alongside greenhouse gas emissions…
New analysis of strontium isotopes reveals how the global carbon cycle has responded to changes in climate and sea level through geologic time. A new…
UC Santa Cruz researchers published a new study — in collaboration with UC Water and the Sierra Nevada Research Institute at UC Merced — that…
Most of Northern California’s kelp forest ecosystem is gone, replaced by widespread ‘urchin barrens’ that may persist long into the future, according to a new…
Study of flowers with two types of anthers solves mystery that baffled Darwin. Some flowers use a clever strategy to ensure effective pollination by bees,…
Researchers used a scanning tunneling microscope to visualize quantum dots in bilayer graphene, an important step toward quantum information technologies. Trapping and controlling electrons in…
A continuous record of the past 66 million years shows natural climate variability due to changes in Earth’s orbit around the sun is much smaller…
First clear confirmation of accretion disk formation in a tidal disruption event without x-ray emissions supports theoretical predictions. When a star passes too close to…
A comprehensive study of four salmon species across all regions of Alaska finds salmon are returning to rivers smaller and younger than in the past….
A simple model explains a wide range of observations by describing a contest between galaxy halos and their central black holes that eventually turns off…
The first end-to-end (‘telomere-to-telomere’) completely gapless DNA sequence of a human chromosome is a major milestone for genomics research. Although the current human reference genome…
Evidence Supports ‘Hot Start’ Scenario and Early Ocean Formation on Pluto A new study suggests that Pluto and other large Kuiper belt objects started out…
UCSC researchers developed a deep-learning framework called Morpheus to perform pixel-level morphological classifications of objects in astronomical images. Researchers at UC Santa Cruz have developed…
Campaigns to plant 1 trillion trees must be undertaken with care and a commitment to long-term management. Restoration ecologist Karen Holl has a simple message…
Researchers demonstrated the mathematical impossibility of representing social networks and other complex networks using popular methods of ‘low-dimensional embeddings.’ Models and algorithms for analyzing complex…
A new scenario based on computer simulations accounts for all of the observed characteristics of the first known interstellar object to visit our solar system….
The bright colors of the chicks of American coots help their parents choose favorites, according to a new study. The American coot is a somewhat…
