Webb finds plethora of carbon molecules around young star

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 ...

Study finds home health aides struggle with mental health

Study Finds Home Health Aides Struggle with Mental Health Home health aides (HHAs) are vulnerable to stress, isolation and depressive symptoms, which impact their own health as well as their patients’ desire to age in place, according to Weill Cornell Medicine researchers. HHAs are a rapidly growing workforce trained and certified to provide personal and medical care, as well as emotional support, in the home. “As a doctor, I’ve learned that home health aides are a critical part of patients’ well-being,” said senior author Dr. Madeline Sterling, ...

Researchers develop microneedle patch to reverse hair loss caused by autoimmune disease

Alopecia areata (AA) is an autoimmune disease characterized by hair loss, which occurs when T cells of the immune system mistakenly attack hair follicles. To restore control over hyperactive immune cells, investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, and MIT developed a cutting-edge approach to deliver T cell regulators directly to sites of hair loss and halt autoimmune activity. Findings, published in Advanced Materials, demonstrated marked and lasting increases in hair regrowth in models of the disease. Our immune system evolved to safeguard against the overactivation that occurs when it mistakenly attacks ...

Discovery highlights ‘critical oversight’ in perceived security of wireless networks

A research team led by Rice University’s Edward Knightly has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street. Contrary to the common belief that these links are inherently secure due to their elevated positioning and highly directive millimeter-wave and sub-terahertz “pencil-beams,” the team exposed a novel method of interception using a ...

Diagnosing damaged infrastructure from space

As infrastructure ages, it becomes more susceptible to failure, which can cause safety and mobility concerns for drivers and pedestrians, and economic woes for taxpayers. A recent study published in “Transportation Research Record” shows that high-resolution synthetic aperture radar (SAR) satellite data can detect infrastructure issues early on, which can help prevent further damage to roads in the same way that annual checkups can help prevent more complex health issues in humans. Led by Dr. Anand Puppala and Ph.D. candidate Amit Gajurel, researchers at Texas A&M University are working on a new method of infrastructure monitoring using Synthetic ...

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 ...

Silkworms help grow better organ-like tissues in labs

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 ...

Scientists ‘read’ the messages in chemical clues left by coral reef inhabitants

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 ...

Mapping noise to improve quantum measurements

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, ...

Tiny predator owes its shape-shifting ability to “origami-like” cellular architecture

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 ...

Widespread use of high-assay low-enriched uranium raises significant nuclear security concerns

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 ...

JWST uncovers features of very-low-mass star’s protoplanetary disk that influence planet composition

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 ...

Researchers identify key differences in inner workings of immune cells

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.
