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…
A giant-impacts phase in the evolution of planetary systems can explain the observations of close-in giant planets with eccentric orbits. As planetary systems evolve, gravitational…
Metallic asteroids are thought to have started out as blobs of molten iron floating in space. As if that’s not strange enough, scientists now think…
Mysterious features seen in light emitted from active galactic nuclei may be due to partial obscuration by dust clouds, according to new study. Many large…
A ‘deep learning’ algorithm trained on images from cosmological simulations has been surprisingly successful at classifying real galaxies in Hubble images. A machine learning method…
Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images…
