An international team of astronomers has used NASA’s James Webb Space Telescope to study the disk of gas and dust around a young, very low-mass star. The results reveal the largest number of carbon-containing molecules seen to date in such a disk. These findings have implications for the potential composition of any planets that might form around this star. Rocky planets are more likely than gas giants to form around low-mass stars, making them the most common planets around the most common stars in our galaxy. Little is known about the chemistry of such worlds, which may be similar to or very different from Earth. By studying the disks from which such planets form, astronomers hope ...

It’s an unusual collaboration. Botanists and archaeologists don’t often work together, unless they’re studying the way people have used plants through time. But a new four-year grant from the National Science Foundation is shaking things up. It provides more than $1 million to study how Mediterranean plants that people have largely ignored evolved and diversified in one of the most formative periods of human history. “The Mediterranean is at the crossroads of Europe,” said Nicolas Gauthier, curator ...

DURHAM, N.C. -- Biomedical engineers at Duke University have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys. By allowing the cells to grow closer together, this new membrane helps researchers to better control the growth and function of the key cells and tissues of any organ, enabling them to more accurately model a wide range of diseases and test therapeutics. The research appears June 4 in the journal Science Advances. Often ...

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex “soup” that is hard for scientists to decipher. Now, researchers in ACS’ Journal of Proteome Research have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms. Plants and animals living in coral reefs release various substances, from complex macromolecules to individual amino acids, into the surrounding water. To determine ...

One of the biggest challenges in quantum technology and quantum sensing is “noise”–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information. Looking deeper at this issue, JILA Associate Fellow and University of Colorado Boulder Physics Assistant Professor Shuo Sun recently collaborated with Andrés Montoya-Castillo, Assistant Professor of Chemistry, and his team to develop a new method for better understanding and controlling this noise, potentially paving the way for significant advancements in quantum computing, ...

For a tiny hunter of the microbial world that relies on extending its neck up to 30 times its body length to release its deadly attack, intricate origami-like cellular geometry is key. This geometry enables the rapid hyperextensibility of the neck-like protrusion, for single-celled predator Lacrymaria olor, a new study reports. The findings not only explain L. olor’s extreme shape-shifting ability but also hold potential for inspiring innovations in soft-matter engineering or the design of robotic systems. Single-celled protists are well known for their ability to perform dynamic morphological changes in ...

In a Policy Forum, R. Scott Kemp and colleagues argue that promoting new nuclear reactor technologies using high-assay low-enriched uranium (HALEU) threatens the international system of controls that has prevented nuclear weapons proliferation for over 30 years. “Governments and others promoting the use of HALEU have not carefully considered the potential proliferation and terrorism risks that the wide adoption of this fuel creates,” write Kemp et al. The authors warn that if HALEU becomes a standard reactor ...

James Webb Space Telescope (JWST) observations have revealed abundant hydrocarbons in the protoplanetary disk surrounding a young, very-low-mass star – findings that provide novel insights into the chemical environment from which many terrestrial planets, in particular, are born. Planets form in disks of gas and dust that orbit young stars. Observations show that terrestrial planets form more efficiently than gas giant planets around very-low-mass stars (VLMSs) – those with less than 0.3 solar masses. Although the chemical compositions of the inner disk regions around higher mass stars ...

Heat production in fat tissue, a trait also known as adipose tissue thermogenesis, evolved over two stages in mammals, fully developing in eutherian mammals after the group’s evolutionary divergence from marsupials, according to a new study. The results could provide insights that inform future therapies related to metabolism and obesity. Many organisms produce heat internally to regulate body temperature. It is thought that the evolution of the ability to maintain high body temperatures provided ...

“There are some things in life you can watch and then never unwatch,” said Manu Prakash, associate professor of bioengineering at Stanford University, calling up a video of his latest fascination, the single-cell organism Lacrymaria olor, a free-living protist he stumbled upon playing with his paper Foldscope. “It’s … just … it’s mesmerizing.” “From the minute Manu showed it to me, I have just been transfixed by this cell,” said Eliott Flaum, a graduate student ...

The MIRI Mid-INfrared Disk Survey (MINDS), led by Thomas Henning from the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, aims to establish a representative disk sample. By exploring their chemistry and physical properties with MIRI (Mid-Infrared Instrument) on board the James Webb Space Telescope (JWST), the collaboration links those disks to the properties of planets potentially forming there. In a new study, a team of researchers ...

From the outside, most T cells look the same: small and spherical. Now, a team of researchers led by Berend Snijder from the Institute of Molecular Systems Biology at ETH Zurich has taken a closer look inside these cells using advanced techniques. Their findings show that the subcellular spatial organisation of cytotoxic T cells – which Snijder refers to as their cellular architecture – has a major influence on their fate. Characteristics that determine a cell’s fate When cells with nuclear invaginations encounter a pathogen, they turn into powerful effector cells that rapidly proliferate and kill the pathogen. Their fellow ...
