T cells' capability to fully prevent acute viral infections opens new avenues for vaccine development

Scientists have discovered that T cells -- white blood cells that can destroy harmful pathogens -- can completely prevent viral infection, to an extent previously thought only possible due to neutralizing antibodies. Their findings reshape our understanding of how our immune system works, paving the way for the design of more effective vaccines. Read more ›

Magma composition may drive volcanic tremor

A new study based on the sampling and analysis of volcanic ash at Cumbre Vieja volcano in the Canary Islands, located off Africa's northwest coast, suggests that the composition of magma could drive tremors during volcanic eruptions. The findings highlight the potential of volcanic ash analysis as a monitoring and forecasting tool. Read more ›

Cleopatra's sister remains missing

anthropologists have analyzed a skull that was found in the ruins of Ephesos (Turkey) in 1929. It was long speculated that it could be the remains of Arsino IV, the sister of the famous Cleopatra. However, the latest anthropological analyses show that the remains are those of a boy between the ages of 11 and 14 who suffered from pathological developmental disorders. His genes point to an origin in Italy... Read more ›

Harnessing microwave flow reaction to convert biomass into useful sugars

Researchers have developed a new process that uses microwave flow reaction and recyclable solid catalysts to efficiently hydrolyze polysaccharides into simple sugars. The developed device utilizes a continuous-flow hydrolysis process, where cellobiose is passed through a sulfonated carbon catalyst that is heated using microwaves, resulting in the efficient conversion of cellobiose to glucose.

Medicare rules may reduce prescription steering

Researchers have found that pharmacy benefit managers (PBMs) -- organizations that negotiate access to medicines for most patients in the United States -- steer patients to use their own pharmacies. However, these pharmacies appear less used in Medicare than in other market segments. These PBMs are part of integrated health care conglomerates that own insurance companies and pharmacies, which may create conflicts of interest. Read more ›

New data on atmosphere from Earth to the edge of space

Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS, which combines numerical modeling with observational data, the team created a nearly 20-yearlong set of data spanning multiple levels of the atmosphere from ground level up to the lower edges of space. Being able to study the interactions of these layers vertically and around... Read more ›

Climate fee on food could effectively cut greenhouse gas emissions in agriculture while ensuring a social balance

Greenhouse gas emissions in agriculture could be significantly reduced in a socially equitable way through a climate fee on food, combined with climate dividends. A new study suggests that pricing greenhouse gas-intensive foods could help meet climate targets for agriculture while generating over 8.2 billion Euros annually. If these funds were redistributed to households through a lump-sum compensation scheme, it would ease the financial burden on households, especially those with... Read more ›

Revealing the 'true colors' of a single-atom layer of metal alloys

Researchers have demonstrated that the direction of the spin-polarized current can be restricted to only one direction in a single-atom layer of a thallium-lead alloys when irradiated at room temperature. The discovery defies conventions: single-atom layers have been thought to be almost completely transparent, in other words, negligibly absorbing or interacting with light. The one-directional flow of the current observed in this study makes possible functionality beyond ordinary diodes, paving... Read more ›

Tongue cancer organoids reveal secrets of chemotherapy resistance

Tongue cancer (TC) cells can enter a chemo-resistant state by activating pathways related to autophagy and cholesterol synthesis, report researchers. Using a large-scale library of TC organoids they developed, the researchers performed comprehensive comparative analyses of chemo-sensitive and chemo-resistant cells. Their efforts shed light on promising avenues toward new treatments for tongue cancer. Read more ›

Rapid return of water from ground to atmosphere through plants

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. Read more ›

Researchers find betrayal doesn't necessarily make someone less trustworthy if we benefit

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:... Read more ›
