Tumor-killing liquid offers a safer "bridge" therapy for patients with liver cancer

A liquid formulation called LATTE has been shown to kill liver cancer cells and potentiate chemotherapy treatments in mice, rabbits, pigs, and human tumor samples. The treatment could provide a safer alternative to traditional methods like thermal ablation, which can be resource-intensive and damage surrounding tissues.

Anti-cancer drug's mode of operation deciphered

Immunologists at the University of Freiburg have solved a mystery about how Rituximab, an anti-cancer drug, targets B tumor cells. The researchers found that CD20 organizes nanostructures on the B cell membrane, and its absence or binding to Rituximab activates resting B cells.

Brazil: Air conditioning equipment days of use will double without climate action

A study found that Brazil's average air conditioning equipment days of use would increase by over 100% in a 4°C warming scenario, significantly impacting space cooling needs. The country's energy consumption and CO2 emissions are projected to rise substantially even in more optimistic future warming scenarios.

New weapon against resistant bacteria

Researchers at the University of Southern Denmark have developed a new effective antibiotic to combat resistant bacteria, which are becoming increasingly difficult to treat. The substance, from the pleuromutilin class, fights multiple types of resistant bacteria via a unique mechanism of action.

Infant and toddler food product names may not accurately reflect ingredient amounts

Researchers found that vegetables in U.S. Department of Agriculture's 'dark green' category were often included in product names, but their average order in the ingredient list was close to fourth. Fruits, particularly juice and juice concentrates, were less likely to appear in product names despite being more prominent in the ingredie...

A recipe for regenerating bioengineered hair

Scientists at RIKEN Center for Biosystems Dynamics Research have identified a population of hair follicle stem cells and developed a recipe for normal cyclical regeneration. In the study, 81% of bioengineered hair follicles generated in NFFSE medium went through at least three hair cycles and produced normal hair.

Combination therapy with radiation shows promise in treating glioblastoma

Researchers at UCLA Jonsson Comprehensive Cancer Center identified a new approach combining an anti-psychotic drug, a statin and radiation to improve overall survival in mice with glioblastoma. The triple combination extended median survival 4-fold compared to radiation alone, providing hope for improved treatment options.

Shining a light on the true value of solar power

Researchers found that grid-tied solar photovoltaic (PV) owners are undercompensated in most of the U.S., as the value of solar eclipses net metering and two-tiered rates. This study provides a generalized model to evaluate the economics of grid-tied PV systems, showing substantial future regulatory reform is needed.

Unusual DNA folding increases the rates of mutations

Research reveals that regions of the human genome with unusual DNA folding tend to have higher mutation rates than others. The study found that non-B DNA sequences, which can fold into different conformations, play a major role in determining regional variation in mutation rates across the genome.

Vaccine confidence grows under new administration, latest CUNY SPH Survey reveals

New Yorkers' acceptance of the Covid-19 vaccine has significantly increased under the Biden Administration, with 64% reporting they would take it in January, up from 55% in September. Disparities persist across racial and ethnic groups, but the largest increase was seen among Black respondents. The survey also found that employed indiv...
