Northeastern researcher Kim Lewis is spearheading an effort to accelerate discovery of new antibiotics as part of a multi-institutional project to tackle the growing problem of antibiotic resistance.

Somatostatin receptors (SSTRs) constitute a crucial family of G protein-coupled receptors (GPCRs) that play pivotal roles in regulating hormone secretion and inhibiting tumor growth.

The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor material—that could be used to send and store quantum information over widely used telecommunications wavelengths. Could these defects in silicon be the best choice among all the promising candidates to host qubits for quantum communications?

Researchers have created a new class of materials called "glassy gels" that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.

In the late 2000s, Scott Saleska noticed something strange going on in the Amazon rainforest. In 2005, a massive drought struck the region. Two years later, Saleska—a University of Arizona professor in the Department of Ecology and Evolutionary Biology—published surprising research that used satellite images to find that the drought resulted in more green growth in large swaths of the Amazon. On the other hand, field researchers saw plants turn brown and some die in response to the drought.

A team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has invented a technique to study electrochemical processes at the atomic level with unprecedented resolution and used it to gain new insights into a popular catalyst material.

It's no secret Aussies love to surf. It's one of our favorite pastimes, but it turns out riding the perfect wave offers more than just the ultimate thrill—it also provides a major boost to the economy, according to new research from The Australian National University (ANU).

A research team led by Prof. Wu Zhengyan and Zhang Jia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a new environmentally friendly way to deliver pesticides using porous microspheres made of halloysite nanotubes (HNTs).

Researchers at the University of Southampton have conducted the most detailed spatial analysis to date of storm surges along the coast of the UK and Ireland.

Corporate earnings announcements are more than just powerful signals to those in the know. After all, it might be expected that sophisticated investors and employees of public companies closely watch news that directly affects their personal wealth. But surprising news about corporate earnings also affects the communities that surround a company, three Stanford Graduate School of Business accounting professors find in a new paper.

As more organizations attempt to increase the representation of women in traditionally male-dominated occupations (such as engineering, technology or banking), new research from George Washington University professor Jennifer Merluzzi indicates that simply hiring more women into these fields may not make diversity efforts more effective.

Pearl millet, an annual grass used for grain and forage, can be a good food source for honey bees and hover flies, according to a recent study published in the Journal of Entomological Science.

A research team consisting of NIMS, AGC Inc., and JASRI has observed partial crystallization of a glass—an initial stage in its transformation into a stronger, more heat resistant glass-ceramic. The study is published in the journal NPG Asia Materials.

A study published in the journal BioScience sheds light on the importance of gray wolves in the western United States. Led by William Ripple, a scientist at Oregon State University and the Conservation Biology Institute, the research delves into the implications of large predator absence on plant and animal communities, and ecosystem functions. It calls attention to "shifting baselines" wherein increasingly degraded conditions are viewed as reflecting the historical state of a system.

Researchers led by Prof. Luo Guangnan from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have made an important discovery about how materials break down and mix on the surfaces inside the experimental advanced superconducting tokamak (EAST). They found that material erosion is caused by excessive heat loads, particle fluxes to the first wall, and energetic ions during the plasma exposure.

Direct reciprocity facilitates cooperation in repeated social interactions. Traditional models suggest that individuals learn to adopt conditionally cooperative strategies if they have multiple encounters with their partner. However, most existing models make rather strong assumptions about how individuals decide to keep or change their strategies.

Chemical sensors whose signals can be amplified by various triggers hold huge potential in multidisciplinary sciences. However, developing such systems was considered a highly challenging task, until a team of researchers from Tokyo Tech recently came up with a novel signal-amplification system that can be flexibly manipulated by a dynamic allosteric effector or a trigger. This new chemosensor system exhibited exceptional signal amplification by altering the sumanene monomer concentrations.

After a year of installation and commissioning, the new electron storage ring at the heart of the Advanced Photon Source—powered by a world's first injection technique—is ready for business.

The severity of anxiety and depressive symptoms in the planetary science community is greater than in the general U.S. population, according to a study led by a University of Hawai'i at Mānoa scientist and published in Nature Astronomy.

An innovative synthesis strategy has opened the way to 2D/3D fused frameworks using inexpensive quinolines as feedstock, report scientists from Tokyo Tech. By leveraging a light-sensitive borate intermediate, the scientists could transform quinoline derivatives into a great variety of 2D/3D fused frameworks in a straightforward and cost-effective manner.

Terahertz waves are being intensely studied by researchers around the world seeking to understand the "terahertz gap." Terahertz waves have a specific frequency that puts them somewhere between microwaves and infrared light. This range is referred to as a "gap" because much remains unknown about these waves.

As detrimental as viruses may sound, they can be helping hands for farmers when it comes to dealing with plant pathogens.

A team of researchers at the University of Zurich has discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil. The research is published in the journal Nature Communications.

A new study published in Physical Review Letters explores the possibility that a strongly supercooled, first-order phase transition in the early universe could explain gravitational wave signals observed by pulsar timing arrays (PTAs).

Young people today are living with the existential threat of climate change. They are witnessing and experiencing record-breaking heat waves, devastating storms, and rising seas. Moreover, youth are watching the actions of governments and industries fall well short of what is needed to address the climate crisis, leaving many young people feeling powerless and hopeless about the future.
