Phys.org / Gaia data reveal three galactic open clusters in detail
Using ESA's Gaia satellite, astronomers have investigated three open clusters in the galactic disk, namely Berkeley 17, 18 and 39. Results of the new study, published January 21 on the arXiv pre-print server, yield crucial ...
Phys.org / Unusual RNA caps reveal previously unknown mechanism of genetic transcription
Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) ...
Phys.org / Webb pushes boundaries of observable universe closer to Big Bang
The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed ...
Phys.org / Superfluids are supposed to flow indefinitely. Physicists just watched one stop moving
Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid. Quantum matter, however, can behave very differently. In the early 20th century, researchers discovered ...
Phys.org / Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limitations
Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in 3D micro- and nanofabrication. ...
Phys.org / The infant universe's 'primordial soup' was actually soupy, study finds
In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a "quark-gluon plasma" that lasted for only a few millionths ...
Phys.org / Deforestation is drying out the Amazon rainforest faster than previously thought
Deforestation is having a more devastating effect on the Amazon rainforest than earlier data suggested. While cutting down large swaths of trees destroys vital habitats, it also harms the region's ability to generate its ...
Phys.org / The first direct observation of a liquid charge density wave
Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows through materials, in some ...
Phys.org / Roadkill offers an ethical alternative to live wildlife in scientific research
A recent review of over 312 studies has identified dozens of unique uses of roadkill in scientific research. The review, published in Biology Letters, discusses the advantages of using roadkill instead of live wildlife and ...
Phys.org / Saltwater crocodiles traveled thousands of miles across the Indian Ocean, genetic study suggests
Accounts from early expeditions to the Seychelles more than 250 years ago described crocodiles as common along the coasts of the archipelago. But after the first settlers established a permanent presence in 1770, the Seychelles ...
Phys.org / How dangling moss saves blue manakin eggs from hungry birds
If something exists in nature, there is most likely a very good reason for it. While there are exceptions, many features "selected" by evolution serve a purpose. Take the blue manakin, a small bird commonly found in southeastern ...
Phys.org / Warming may increase mangrove methane emissions—but these forests remain powerful carbon sinks
Mangrove forests play an important role in the global carbon cycle, particularly within the marine carbon system. Growing along tropical and subtropical coastlines, these salt-tolerant trees are among nature's most efficient ...
