Scientists discover nanoclusters effective for cancer in the second near-infrared synergy therapy

Researchers have developed a new type of nanocarrier that combines photothermal, chemo-therapy, and chemodynamic therapy to target and destroy cancer cells. The nanoclusters, which are responsive to near-infrared light, show a significant inhibitory effect on mouse tumor growth in vivo experiments.

When a single tree makes a difference

A new study from American University found that individual trees can help mitigate urban heat, particularly in evening hours. The research showed that neighborhoods with at least half of the area covered by canopy were 1.4 degrees Celsius cooler than those with few trees.

Transport in 2050: Safer, cleaner and cost efficient?

A Cornell University-led team projects that vehicle electrification, driverless cars, and ride sharing could prevent 5,500 premature deaths and save $58 billion annually in the US by 2050. The study also finds that vehicle electrification is the most important piece for carbon mitigations and health benefits.

Songbirds like it sweet!

Researchers found that songbirds can sense sweetness regardless of their primary diets, with the ability emerging early within the songbird radiation. The team identified the molecular basis of this ability and found that it has been conserved in nearly half of all birds living today.

Having a nice glass of French wine?

A new study from the University of California, Davis, found that France's Appellation d'Origine Contrôlée (AOC) system led to a significant increase in market value for French wines. The AOC system created production standards and mandatory tasting requirements, allowing wine growers to improve quality and be rewarded for it.

Sea-level rise may worsen existing Bay Area inequities

Researchers found that coastal communities in San Mateo County are at risk of financial instability from flooding, with lower-income households disproportionately affected. The study's new methodology aims to provide a human-centered approach to risk assessment, focusing on the residents most likely to lose their livelihoods when water...

Two-thirds of romantic couples start out as friends, study finds

A new study found that nearly 75 percent of research on relationship beginnings focused on romance between strangers, while only eight percent examined friendships-to-romance transitions. The study analyzed data from over 1,900 university students and crowdsourced adults, finding a strong correlation between friends-first initiation an...

Coastal ecosystems worldwide: Billion-dollar carbon reservoirs

Coastal ecosystems worldwide are estimated to have a significant impact on the global economy, with countries like Australia and Indonesia storing large amounts of carbon. The study found that these countries generate annual welfare gains of around $26.4 billion from reduced climate change costs, while other nations like India and Chin...

Promising new research on aggressive breast cancer

A new study published in PNAS has identified a protein called AXL as a crucial player in hypoxia, which promotes cancer progression and resistance to treatment. By blocking the action of this protein, researchers observed improved recovery of blood vessels and revitalization of the tumour's immune environment.

Immune system 'clock' predicts illness and mortality

The study found that a single-number quantitative measure, the inflammatory-age score, tracks well with a person's immunological response and the likelihood of incurring aging-related diseases. Blood levels of CXCL9, a cytokine secreted by certain immune cells, contribute more powerfully than any other clock component to the inflammato...
