Astronomers discover first step toward planet formation
Solving the mystery of how planets like Earth were formed is an important question for understanding the origin of life. Planets are thought to form when interstellar dust and gas collect in a protoplanetary disk surrounding a protostar, but it has b.....»»

The upside-down capacitor in mid-‘90s Macs, proven and documented by hobbyists
A "copy/paste error" on a Mac logic board has led to some restoration problems. "Am I the first person to discover this?" is a tricky question when it comes to classic Macs, some.....»»
Scientists reveal structural link for initiation of protein synthesis in bacteria
Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mys.....»»
Bio-inspired droplet-based systems herald a new era in biocompatible devices
Oxford University researchers have made a significant step toward realizing a form of "biological electricity" that could be used in a variety of bioengineering and biomedical applications, including communication with living human cells. The work wa.....»»
Archaeologists discover 4,000-year-old canals used to fish by predecessors of ancient Maya
Long before the ancient Maya built temples, their predecessors were already altering the landscape of Central America's Yucatan peninsula......»»
Scientists reveal possible role of iron sulfides in creating life in terrestrial hot springs
An international team of scientists has published a study highlighting the potential role of iron sulfides in the formation of life in early Earth's terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction.....»»

Astronomers discover a "hot Neptune" in a tight orbit
A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as these form......»»
Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the lowest mass ratio contact bi.....»»
Magnetically driven vortices may be generating Earth-size concentrations of hydrocarbon haze at Jupiter"s poles
While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet's north and south poles that appear and disappear seemingly at r.....»»
X-ray measurements reveal an unexpected role for copper in photocatalysts
Copper is a promising catalyst for sustainably converting carbon dioxide into substances with more electrons (called reduced species). This is an important step in converting carbon dioxide into fuels. This reaction is often initiated by electrical e.....»»
Astronomers measure cosmic electrons at the highest energies to date
Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unpreced.....»»
A 4.45 billion-year-old crystal from Mars reveals the planet had water from the beginning
Water is ubiquitous on Earth—about 70% of Earth's surface is covered by the stuff. Water is in the air, on the surface and inside rocks. Geologic evidence suggests water has been stable on Earth since about 4.3 billion years ago......»»
Unusual supernova observations grant astronomers a peek into the cosmic past
An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed......»»
Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published November 19 in The Astr.....»»
Study discovers formation of Criegee intermediates from photochemical oxidation of alkenes
