Both intuition and past research suggest that whether people deem someone trustworthy depends on that person's past behavior and reputation for betrayal. In a series of experiments, psychologists found that subjects regarded those who previously exhibited that behavior as less trustworthy. However, when the betrayal benefited them or had no effect on them, participants regarded the betrayer as trustworthy. This pattern was largely consistent across the types of relationships studied: friendships, romantic relationships and professional relationships.

A new study provides the first comprehensive global estimates of the amount of water stored in Earth's plants and the amount of time it takes for that water to flow through them. The information is a missing piece of the puzzle in understanding the global water cycle and how that cycle is being altered by changes in land use and climate.

Antibiotic-resistant Salmonella is a serious public health concern that has increased in recent years as the bacteria have developed ways to survive drugs. According to the U.S. Centers for Disease Control and Prevention, people can get Salmonella from eating contaminated food products or from infected people or animals -- typically via unintentional contact with feces via touching hands or stroking a pet. However, researchers have found that household dogs are an overlooked transmission point for zoonotic pathogens such as nontyphoidal Salmonella, which can cause diarrhea, fever and abdominal cramps, with some infections potentially having life-threatening complications.

An international research team has discovered a new type of skeletal tissue that offers great potential for advancing regenerative medicine and tissue engineering.

RNA is the molecule that reads the genetic information stored in DNA. It's critical for the proper functioning of cells, and in a new study scientists have discovered a way of tagging RNA with a glowing bioluminescent molecule that allows them to track RNA in real time as it moves throughout the body. The work promises to help scientists better understand everything from the way viruses propagate to how memories form in the brain.

Contrary to the long-held belief that the mid-career crisis plagues everyone, new research suggests that job satisfaction follows a U-shaped trajectory only for managerial and professional workers. This provocative finding challenges societal perceptions surrounding midlife and calls for a revaluation of workplace support for individuals in their 40s and 50s.

Construction materials such as concrete and plastic have the potential to lock away billions of tons of carbon dioxide, according to a new study by civil engineers and earth systems scientists. The study shows that combined with steps to decarbonize the economy, storing CO2 in buildings could help the world achieve goals for reducing greenhouse gas emissions.

Laboratory experiments designed to deform ice at its pressure-melting temperature were like grabbing a bagel at the top and the bottom, then twisting the two halves to smear the cream cheese in the middle, according to new research. The resulting data could lead to more accurate models of temperate glacier ice and better predictions of glacier flow and sea-level rise.

Researchers have developed IRIS, a smart ring that allows users to point and click to control smart devices. The prototype Bluetooth ring contains a small camera which sends an image of the selected device to the user's phone. The user can control the device clicking a small button or -- for devices with gradient controls, such as a speaker's volume -- rotating the ring.

Researchers have developed new measurement techniques and methods to measure emissions from category-L vehicles in realistic operation and to determine corresponding limit values.

International research has found almost 30,000 wild species have been traded in the United States, according to data captured by US wildlife trade monitoring organization Law Enforcement Manage Information System.

Researchers have recently achieved a significant breakthrough in the development of next-generation carbon-based quantum materials, opening new horizons for advancements in quantum electronics. The innovation involves a novel type of graphene nanoribbon (GNR), named Janus GNR (JGNR). The material has a unique zigzag edge, with a special ferromagnetic edge state located on one of the edges. This unique design enables the realization of one-dimensional ferromagnetic spin chain, which could have important applications in quantum electronics and quantum computing.

Scientists have developed inhalable lung cancer therapeutics utilizing mucoadhesive proteinic nanoparticles.

Researchers have published a prospective, randomized and controlled study on the use of extracorporeal photopheresis (ECP) in lung transplantation. The findings could significantly change the standard procedure for rejection reactions after lung transplants.

Cancer metastasis -- the spread of cancer to other organs -- is the leading cause of death among cancer patients. Researchers have now uncovered a 'genetic signature' of 177 genes shared across multiple cancer types that drives this deadly process.

A battery that needs feeding instead of charging? This is exactly what researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors for agriculture or research in remote regions. Once the work is done, it digests itself from the inside.

Current state policies aren't enough to curb food waste. Study shows states are falling short of the reduction goals set by the U.S. Environmental Protection Agency.

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Now, researchers have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for more reliable quantum computation.

Hydroclimate whiplash -- rapid swings between intensely wet and dangerously dry weather -- has already increased globally due to climate change, with further large increases expected as warming continues, according to a team of researchers.

A team has developed a new method that facilitates and improves predictions of tabular data, especially for small data sets with fewer than 10,000 data points. The new AI model TabPFN is trained on synthetically generated data before it is used and thus learns to evaluate possible causal relationships and use them for predictions.
