Pharmaceutical waste and contaminants present a growing global concern, particularly in the context of drinking water and food safety. Addressing this critical issue, a new study by researchers at Bar-Ilan University's Department of Chemistry and Institute of Nanotechnology and Advanced Materials has resulted in the development of a highly sensitive plasmonic-based detector, specifically targeting the detection of harmful piperidine residue in water.

The Los Angeles school district on Wednesday unveiled a much-awaited AI tool named "Ed" to serve as a new student adviser, programmed to tell its young users and their parents about grades, tests results and attendance—while giving out assignments, suggesting readings and even helping students cope with nonacademic matters.

How are profitability, market share, and the digitalization of a company connected? To get to the bottom of this question, the researchers developed a new profitability model based on over 6,000 cases from around 800 US companies from the last 25 years. In order to measure the degree of digitalization, the companies' annual financial statements were combed for certain keywords that indicate digitalization.

A long-term sea level dataset shows ocean surface heights continuing to rise at faster and faster rates over decades of observations.

New research published in the Journal of the Science of Food and Agriculture illuminates the untapped potential of the shrub sea buckthorn as a rich source of natural antioxidants in North America.

Major League Baseball's opening day is March 28, and chances are, some players will be working a bit harder this season than others.

White men who have experienced workplace harassment themselves are more likely to support efforts to combat race and gender bias in their organizations, according to a new University of Michigan study. The findings appear in the American Journal of Sociology.

First impressions are often long-lasting and can impact a professional career in profound and unintended ways. Today, because initial business contacts often happen online—think an emailed intro, a phone text, or a Zoomed teleconference—many individuals form first impressions through these media.

Particles colliding in accelerators produce numerous cascades of secondary particles. The electronics processing the signals avalanching in from the detectors then have a fraction of a second in which to assess whether an event is of sufficient interest to save it for later analysis. In the near future, this demanding task may be carried out using algorithms based on AI, the development of which involves scientists from the Institute of Nuclear Physics of the PAS.

Plants have an extremely high capacity to adapt to their environment. When the seeds of pea sprouts left over from cooking are soaked in water, the sprouts and leaves grow back. Associate Professor Kondo Yuki of Kobe University's Graduate School of Science has focused his research on vascular bundles, which are essential for environmental adaptation.

With Easter just around the corner, we are surrounded by a ubiquity of eggs and adorable yellow chicks that symbolize life and resurrection. In stark contrast is the fact that around seven billion male layer chicks, are shredded or gassed alive by the egg industry every year, just hours after they hatch. Male chicks of course cannot lay eggs, and they are furthermore not worth fattening up like broilers, due to decades of specialized breeding toward either egg laying or meat production—but not both.

For most people, reading about the difference between a global average temperature rise of 1.5 C versus 2 C doesn't conjure up a clear image of how their daily lives will actually be affected. So, researchers at MIT have come up with a different way of measuring and describing what global climate change patterns, in specific regions around the world, will mean for people's daily activities and their quality of life.

What is a city? What are the geographical conditions and social factors that lead to the concentration of population in an area, and how does urbanization progress? And what is needed to create urban environments that meet the diversifying lifestyles and needs of people?

In 2020, a line of severe thunderstorms unleashed powerful winds that caused billions in damages across the Midwest United States. A technique developed by Penn State scientists that incorporates satellite data could improve forecasts—including where the most powerful winds will occur—for similar severe weather events.

Human artificial chromosomes (HACs) capable of working within human cells could power advanced gene therapies, including those addressing some cancers, along with many laboratory applications, though serious technical obstacles have hindered their development. Now a team led by researchers at the Perelman School of Medicine at the University of Pennsylvania has made a significant breakthrough in this field that effectively bypasses a common stumbling block.

By analyzing digital copies of an incredibly rare and obscure 17th-century Italian religious text, a University of Bristol academic has revealed that a long-lost document previously thought to have been written by William Shakespeare's father belongs, in fact, to his relatively unknown sister Joan.

"First comes love, then comes marriage"—so goes the classic children's rhyme. But not everyone agrees. Increasingly, the idea that love is the most important reason to marry—or at least to stay married—is under attack. Republican pundits and lawmakers have been pushing back on the availability of no-fault divorce, challenging the idea that not being in love is a valid reason to end a marriage.

The Noto Peninsula earthquake that occurred on January 1 brought the challenges of earthquake-prone Japan back into sharp focus. With a magnitude of 7.6, surpassing the 1995 Kobe earthquake (Great Hanshin-Awaji earthquake), it caused significant upheaval in the landscape and substantial ground uplift. The large number of aftershocks is also notable. What exactly happened under the Noto Peninsula?

Many important medicines, such as antibiotics and anticancer drugs, are derived from natural products of bacteria. The enzyme complexes that produce these active ingredients have a modular design that makes them ideal tools for synthetic biology. By exploring protein evolution, a team led by Helge Bode from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, has found new "fusion sites" that enable faster and more targeted drug development.

The moon is practically begging to be explored, and the momentum to do so is building. The Artemis Program's effort to return astronauts to the moon for the first time since the Apollo missions captures a lot of attention. But there are other efforts underway.

Heat shock proteins (HSPs) are the chaperones of cellular stress response because they help guide the folding and unfolding of other proteins.

After more than 70 successful flights, a broken rotor ended the remarkable and groundbreaking Ingenuity helicopter mission on Mars. Now, NASA is considering how a larger, more capable helicopter could be an airborne geologist on the Red Planet. For the past several years scientists and engineers have been working on the concept, proposing a six-rotor hexacopter that would be about the size of the Perseverance rover.

Understanding the structure of crop canopies is essential for optimizing crop production as it significantly influences resource utilization efficiency, yield and stress resistance. While research has integrated canopy studies into various agricultural practices, the construction of accurate 3D models remains challenging due to complex spatial distributions and technological limitations.

Researchers from the University of Southampton have developed technology to help scientists observe proteins in motion. Understanding how proteins move will allow novel drugs to be designed.

When you are reading this article, there are multiple hormones working diligently inside your body to stabilize your health status. Just as in human beings, it is impossible for plants to grow and reproduce without being regulated by phytohormones. One of the phytohormones is the brassinosteroid (BR) hormone, also named as the sixth phytohormone.
