An international team of astronomers including researchers at the University of Arizona Lunar and Planetary Laboratory has unveiled groundbreaking findings about the disks of gas and dust surrounding nearby young stars, using the powerful Atacama Large Millimeter/submillimeter Array, or ALMA. [...]
In the world of particle physics, where scientists unravel the mysteries of the universe, artificial intelligence (AI) and machine learning (ML) are making waves with how they're increasing understanding of the most fundamental particles. Central to this exploration are parton distribution functions (PDFs). These complex mathematical models are crucial for predicting outcomes of high energy physics experiments that test the Standard Model of particle physics. [...]
A team of planetary scientists, ecologists, and marine biologists affiliated with several institutions in the U.S. and one in the U.K., has found evidence suggesting that parts of the world's oceans have already passed what has come to be known as a planetary boundary. [...]
Forest fire prevention and control agencies in São Carlos, in the interior of the state of São Paulo, Brazil, will soon have help from the sky to detect fires more quickly and combat them before they grow out of control and cannot be extinguished. [...]
Acyl carrier protein (ACP) plays a central role in fatty acid biosynthesis, acting as a molecular "shuttle" that carries, protects, and delivers elongating acyl chains to various enzymatic partners. However, the high flexibility of ACP and the instability of its thioester‐linked intermediates have long hindered detailed structural characterization of its dynamic behavior. [...]
The reef fish population in the Gulf is growing ahead of the 2025 red snapper season, according to the University of South Alabama's annual fish survey. [...]
A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere. [...]
Previous research has asserted that women and men in gender-equal countries differ more in their preferences than women and men in less equal countries, for example, by making more traditional educational choices. This relationship is known as the gender-equality paradox. [...]
A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan. [...]
When negotiating a salary or a purchase, negotiators often make strategic use of emotions. Social psychologist Zi Ye demonstrates how one negotiator might fake happiness, exaggerate disappointment, or conceal anger—and how the other side may either appreciate or disapprove of such emotional tactics. Ye earned his Ph.D. on 20 May. [...]
For decades it was thought that the family system of the ancient Egyptians was very similar to our own. However, Ph.D. candidate Steffie van Gompel explains that the reality is somewhat different. "In Egyptian families, it was often the eldest son versus the rest of the children." [...]
The sharpest images of the universe are created when radio telescopes around the world work together. For the first time, the world's largest network of radio telescopes, EVN, has observed together with South Africa's MeerKAT, the southern hemisphere's most powerful radio telescope. The images, of a distant black hole jet, open up new possibilities for cosmic discoveries and international cooperation. [...]
Understanding how drug delivery systems distribute in vivo remains a major challenge in developing nanomedicines. Especially in the lung, the complex and dynamic microenvironment often limits the effectiveness of existing approaches. [...]
Forest fires are a fundamental force in Earth's dynamics with a direct impact on human health, food security, and biodiversity. From air quality to landscape configuration and resource availability, the consequences of fire have influenced the development of society throughout history. Their effects on the oceans, though less known, are equally significant. [...]
A research team led by Professor Eiji Inoue from the Department of Biology, Faculty of Science, Toho University have conducted a study on the Japanese weasel (Mustela itatsi). The Japanese weasel is an endemic species to Japan, but it was intentionally introduced to a number of non-native islands and its naturalization on some islands has resulted in severe negative consequences to the local ecosystems. [...]
A group from Nagoya University in Japan has succeeded in performing a difficult reaction to build the bases that make polycyclic aromatic hydrocarbons (PAHs) used in organic LEDs, transistors, and solar cell technology. Their technique allows the creation of these complex molecules—valued for their unique electronic, optical, and medicinal properties—in a new, cleaner, more efficient way. The study was published in Nature Communications. [...]
Extended drought and warm weather are damaging South Australia's marine ecosystems, and periodic flooding of the River Murray poses another major risk. [...]
Scientists warn that the future of our oceans and climate goals depends on reconnecting the ecological threads that hold coastal habitats together. [...]
Even the best products won't meet expectations if they are packed poorly—packaging matters. The same goes for drug delivery. Osaka Metropolitan University researchers have uncovered the critical role played by solvents in how effectively drugs can be loaded into metal–organic frameworks (MOFs), a promising class of drug carriers. [...]
Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria. [...]
A natural alternative to pesticides may be hiding in a misunderstood plant compound—but it could come at an environmental cost. [...]
Tuberculosis is the world's leading infectious cause of death, killing more than one million people each year. When the antibiotic bedaquiline was introduced in 2012, it was the first new tuberculosis drug in over 40 years. Bedaquiline quickly became the key drug in all standard drug-resistant tuberculosis regimens globally. Unfortunately, clinical Mycobacterium tuberculosis strains rapidly become resistant to bedaquiline, predominantly by overexpression of MmpL5. [...]
An advance by Monash University scientists could transform agriculture with designer crops suited to the climate of individual regions. [...]
A team of researchers from Tohoku University, National Institutes for Quantum Science and Technology (QST), and Cambridge University have demonstrated a new way to make a unique material called tin sulfide (SnS), which can help build better and more compact electronic devices. Their findings are published in Nano Letters. [...]
In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing down activity when things get too intense. A new study from Vanderbilt University reveals that these molecular "defenders" evolve differently depending on where they sit in the signaling pathway. [...]
A major cause of hospital-acquired infections, the super bacteria Methicillin-resistant Staphylococcus aureus (MRSA), not only exhibits strong resistance to existing antibiotics but also forms a dense biofilm that blocks the effects of external treatments. [...]
A new global study shows that people in societies characterized by corruption, inequality, poverty, and violence are more likely to develop aversive, "dark" personality characteristics such as selfishness or spitefulness. [...]
The drug pipeline—the process through which a potential new drug gets discovered, tested, approved, and marketed—is a notoriously long and arduous process, and even the most promising drugs can languish or die on the road to the clinic. [...]
