A newly-released Hubble image shows Messier 88, a black hole-powered spiral galaxy that is gradually plunging toward the crowded heart of the Virgo Cluster. This image, taken with the Wide Field Camera 3 (WFC3) instrument aboard the NASA/ESA Hubble Space Telescope, shows the spiral galaxy Messier 88. Image credit: NASA / ESA / Hubble / D. Thilker / MAUVE-HST Team. Messier 88 is located approximately...
New observations from NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft reveal that the Zwan-Wolf effect — a phenomenon once thought unique to Earth’s magnetosphere, in which charged particles are squeezed like toothpaste coming out of a tube along magnetic structures called flux tubes — is also reshaping the Red Planet’s upper atmosphere. An artistic representation...
For more than four and a half millennia, the Khufu Pyramid has stood on the Giza plateau, enduring dozens of earthquakes without serious structural damage. New research led by Egypt’s National Research Institute of Astronomy and Geophysics offers a quantitative explanation for this remarkable durability. It shows that the structure’s natural vibration frequencies differ sharply from those of...
Paleontologists have recovered the fossilized remains of three hyaenodont species, including one previously unknown to science, from Miocene sediments in Pakistan. Metapterodon anari.

A marine biologist studying the photophores of a bioluminescent fish species found needle-shaped guanine crystals that scatter and redirect light instead of merely reflecting it, a discovery that could inspire more efficient biomedical and optical devices.

Mathematicians from University College London and the University of California, Davis, have published a mathematical proof that the Universe’s accelerating expansion can be explained without dark energy, dealing a serious blow to the Lambda-cold dark matter model — the standard cosmological model that has stood for nearly 30 years. Alexander et al. provide a mathematical proof that instabilities...
In a small randomized trial in the United Kingdom, adults who added a serving of 100% fruit juice or a smoothie to a healthier diet reported lower depression scores after four weeks. People who drink a glass of 100% fruit juice or a smoothie each day as part of the UK’s 5-a-day healthy eating guidance see improvements in their mental wellbeing.

Scientists have extracted and analyzed proteins from the tooth enamel of six Homo erectus individuals who lived in China roughly 400,000 years ago, offering an unprecedented glimpse into the genetic makeup of one of humanity’s most successful and far-ranging ancestors. Their results suggest that Homo erectus may have carried genetic variants that were later passed to Denisovans and eventually...
Unusual gases rising from geothermal springs within the Kafue Rift of Zambia suggest a deep fracture in Earth’s crust could mark the early stages of a new tectonic boundary. Location map of the extensional zone within the Central African Plateau of Zambia. The Kafue Rift is connected to the Luano and Luangwa rifts to the NE, and the Western branch of the EARS at the Rukwa rift (RRB) and Rungwe...
