- Methods to enhance the ocean's uptake of carbon dioxide (CO₂) are being explored to help tackle the climate crisis. However, some of these approaches could significantly exacerbate ocean deoxygenation. Their potential impact on marine oxygen must therefore be systematically considered when assessing their suitability.
- This week, the state of Florida reached a "startling milestone" in the effort to eradicate invasive Burmese pythons in the Everglades. Archaeologists found the 6,000-year-old remains of a teen girl with cranial modification. And a study of the moons of Uranus provides more confirmation that the planet is just really weird.
- Two key protein structures in the body are being visualized for the first time, thanks in part to the latest technology in the University of Cincinnati's Center for Advanced Structural Biology—potentially opening the door for better designed therapeutics.
- Air pollution causes health problems and is attributable to some 50,000 annual deaths in the United States, but not all air pollutants pack the same punch.
- A new platform for engineering chiral electron pathways offers potential fresh insights into a quantum phenomenon discovered by chemists—and exemplifies how the second quantum revolution is fostering transdisciplinary collaborations that bridge physics, chemistry, and biology to tackle fundamental questions.
- Coastal planners take heed: Newly uncovered evidence from fossil corals found on an island chain in the Indian Ocean suggests that sea levels could rise even more steeply in our warming world than previously thought.
- 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.
- 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.
- 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.
- 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 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.
- 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.
