Preserved presolar silicate grains found in Ryugu samples
A large international team of space scientists and geochemists has found preserved presolar silicate grains in surface samples collected from the Ryugu asteroid by the Japanese space probe Hayabusa2 in 2018 and 2019 and returned to Earth in 2020. In.....»»
X-ray method enables micron-resolution imaging of living organisms over long time periods
Researchers have developed an X-ray imaging technique that can produce detailed images of living organisms with a much lower X-ray dose than previously possible. The advance enables small organisms or other sensitive samples to be studied at high res.....»»

Earliest-known fossil mosquito suggests males were bloodsuckers too
Researchers reporting in the journal Current Biology on December 4 have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthpart.....»»
British research ship crosses paths with world"s largest iceberg as it drifts out of Antarctica
Britain's polar research ship has crossed paths with the largest iceberg in the world—a "lucky" encounter that enabled scientists to collect seawater samples around the colossal berg as it drifts out of Antarctic waters, the British Antarctic Surve.....»»
Meteorites likely source of nitrogen for early Earth, Ryugu samples study finds
Micrometeorites originating from icy celestial bodies in the outer solar system may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published in Nature Astronomy by an intern.....»»
Inferring causative microbial features from metagenomic data of limited samples
Increasing evidence has shown an association between gut microbiota and numerous diseases inferred by metagemomic (MWAS), indicating the microbiota as one of the most promising and effective strategies to control these diseases. However, inferring ca.....»»
Separating out signals recorded at the seafloor
Blame it on plate tectonics. The deep ocean is never preserved, but instead is lost to time as the seafloor is subducted. Geologists are mostly left with shallower rocks from closer to the shoreline to inform their studies of Earth history......»»
3D folding of the genome: Theoretical model helps explain how cell identity is preserved when cells divide
Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell.....»»
ALMA observation of young star reveals details of dust grains
One of the primary goals of the Atacama Large Millimeter/submillimeter Array (ALMA) is to study the formation and evolution of planetary systems. Young stars are often surrounded by a disk of gas and dust, out of which planets can form......»»
NASA pauses Mars Sample Return mission due to ongoing budget issues
NASA’s iconic mission to bring back samples of Martian soil and rocks has gone awry. The space agency shared that the Mars Sample Return mission … The post NASA pauses Mars Sample Return mission due to ongoing budget issues appeared first on.....»»
Feathery moa"s fossilized footprints, ancient age revealed
Cosmogenic nuclide dating, a method commonly used in dating coastal areas and alluvial riverbeds for landscape reconstruction, is also useful for calculating the age of trace fossils, such as a footprint, where no remains of the animal are preserved......»»
Bioengineers send cardiac muscle samples into space to study heart cell biology in microgravity
Mount Sinai's Cardiovascular Research Institute is sending bioengineered human heart muscle cells and micro-tissues into space for the first time on NASA's 29th SpaceX commercial resupply services mission, which launched Thursday, November 9. The "Sp.....»»
Orkney"s lost tomb—how researchers made the Neolithic discovery
Orkney in the north of Scotland is renowned for its remarkably well-preserved monuments. Many of these are Neolithic (10,000 BC to 2,200 BC) and consist of stone circles and chambered tombs, which are still highly visible in the landscape. Chambered.....»»
Insect trapped in amber reveals the evolutionary battles of ancient Europe
An extraordinary insect preserved in amber is opening our ears to a world of communication beyond our hearing. New research on an extinct katydid in the Natural History Museum's collection reveals that katydids have been using ultrasounds for million.....»»
Recent fossil discovery suggests the first dinosaur egg was leathery
The discovery of several exceptionally preserved reproduction-related dinosaur specimens over the last three decades has improved our knowledge of dinosaur reproductive biology. Nevertheless, due to limited fossil evidence and a lack of quantitative.....»»
Water on asteroid Ryugu"s parent found to have shaped distribution of its elements
A large international team of space scientists, geochemists, and engineers, has found that water that existed on the parent of Ryugu had an impact on the distribution of elements on the asteroid. In their paper published in the journal Science Advanc.....»»
Extracellular vesicles captured by sustainable wood cellulose-based nanofiber may identify and improve cancer treatment
A research team in Japan, led by Nagoya University's Akira Yokoi, has developed an innovative technique using cellulose nanofiber (CNF) sheets derived from wood cellulose to capture extracellular vesicles (EVs) from fluid samples and even organs duri.....»»
Oldest known samples of brittle stars from supercontinent Gondwana discovered in South Africa
A small team of paleontologists with members from Rhodes University, in South Africa, the National Museum of Natural History, Luxembourg City, and the University of Oxford, in the U.K., has discovered the oldest known brittle star samples from the su.....»»
NASA"s OSIRIS-REx mission surpasses goal for collection of asteroid samples
