A study led by Wageningen University & Research shows that human interventions have significantly changed tides in river estuaries over the past centuries. In many regions around the world, the difference between high and low tide has increased, and the tidal wave is moving inland faster. These changes often appear to have a greater impact than the effects of sea-level rise.
Designing molecules is one of chemistry's most complex challenges. From life-saving drugs to advanced materials, each compound requires a precise sequence of reactions. Planning these steps demands both technical knowledge and strategic insight, making it a task that often relies on years of experience.
Researchers have demonstrated the first "all-in-one" cocatalyst for photocatalytic overall water splitting, a breakthrough that could simplify the production of clean hydrogen fuel. The discovery marks an important step toward practical technologies that use sunlight and water to generate hydrogen, a key energy carrier expected to play a major role in building a decarbonized and sustainable society.
Urea is an extremely important chemical, especially for fertilizers. But, making urea is energy intensive and relies heavily on fossil fuels. However, new findings from Griffith University and the Queensland University of Technology have highlighted new ways to produce urea electrochemically, using electricity and waste gases such as carbon monoxide (CO) and nitrogen oxides (NO) instead.
Past research has shown that even though science is commonly viewed as essential for effective policymaking, Democrats and Republicans cite different scientific research when creating policy—even when addressing the same topic. Now, a new Northwestern study analyzing congressional reports, hearings and think tank publications from around the country, has found that bipartisan citations, while rare, highlight papers of exceptional scientific influence. Policy documents citing these papers also receive more citations, amplifying their policy impact—and perhaps providing a pathway for future bipartisan successes.
Gene editing has emerged as a powerful approach for targeting the genetic causes of disease, but getting the editing machinery into the right cells efficiently, safely, and at the scale needed for therapies remains one of the biggest set of challenges in the field.
Many important objects in the world can be divided into two categories based on their chirality or handedness, including molecules important for life such as amino acids. Such chiral objects (formally defined as objects which are not identical to their mirror images) are often characterized by a structure which twists in a given direction.
Researchers at the Indian Institute of Science (IISc) have implemented an advanced microscopy technique to visualize multiple biomolecules inside the nucleus of a cancer cell simultaneously at incredibly high resolution. The biomolecules they visualized include critical components of the cell's transcription machinery and proteins that provide structural support to the nucleus—providing one of the first detailed maps of nuclear organization.
Some innovations in physics come from entirely new technologies, others from fresh theoretical insights. Others still take shape by bringing together existing tools in new ways, working out how to combine them to outperform other solutions. The branch of particle physics that studies weakly interacting particles—such as neutrinos and some types of dark-matter candidates—could use innovative detection approaches: technological challenges in this research area quickly become practical as well as economic, as increases in detector volume and spatial resolution improve the sensitivity to the processes producing the particles of interest. Similarly, demanding targets on instrument capability apply to the calorimeters used in collider experiments.
A pioneering project led by researchers from the University of Stirling and the Max Planck Institute has opened the door for new insights into the evolutionary origins of human intelligence, by compiling the largest dataset of great ape cognition available globally.
This week, researchers reported that malaria influenced population distribution in Africa thousands of years ago. Mathematicians at MIT report that classical physics formulations can explain quantum phenomena. And a study found that electron spin causes mirror-image molecules to behave differently from one another.
They already have the bill of a duck, the tail of a beaver, lay eggs like reptiles and have venom like snakes.
An international research team led by DTU has developed a new magnetic material that features a stable internal magnetic structure, almost no external magnetic field, and retains these properties above room temperature. These characteristics may be important for future generations of electronic technologies, for example, within fields where magnetic properties are used instead of electrical charge to process information—so-called spintronics. The results have been published in the journal Nature Chemistry.
When humans are moving as a crowd, their movements tend to be highly coordinated, similarly to the collective motions of bird flocks or other groups of animals. These group behaviors can limit collisions in dynamic environments, allowing individuals to reach their destinations safely.
Scientists have mapped in unprecedented detail the structure of Vibrio bacteria, which can cause life-threatening infections linked to antibiotic resistance. The King's College London team behind the study, published in Nature Communications, say the finding could provide new targets for life-saving treatment.
