UT Southwestern researchers kill latent HIV-infected cells using immunotoxin

Researchers have successfully developed an immunotoxin that kills over 99% of latent HIV-infected cells using a monoclonal antibody and ricin. The treatment targets CD45RO molecules found on the surface of memory T cells, which are difficult to target due to their low abundance.

Clinical trial demonstrates that bone marrow transplant followed by vitamin A-derivative treatment improves survival from a major childhood cancer

A randomized clinical trial showed that combining bone marrow transplant and high-dose chemoradiotherapy significantly improves disease-free survival in children with neuroblastoma. The addition of vitamin A-derivative treatment further increases survival rates by nearly three-fold.

Modeling the paths of soaring birds helps pilots

Researchers developed a model to predict bird flight patterns, enabling pilots to adjust their routes and altitudes. The model can forecast bird locations and altitudes hours in advance, reducing the risk of bird strikes and damage to windshields and turbine engine blades.

Vegans likely short on calcium, experts say

A study by Purdue University found that vegan diets lack sufficient calcium, even with dairy-free alternatives. Experts recommend drinking milk or adding fortified foods/supplements to meet the daily calcium requirement. Vegans may need to consume large amounts of calcium-rich vegetables like broccoli and kale to get enough.

Racial disparity in lung cancer treatment must be overcome, UCSF specialists assert

Lung cancer treatment disparities between blacks and whites are attributed to racial attitudes and biases, affecting surgical resection rates and survival outcomes. UCSF specialists emphasize the importance of addressing these inequities through improved communication, screening tests, and clinical trials.

Use it or lose it applies to nervous system, scientists find

Researchers found that a muscle protein rapidly disappears from synapses when not receiving nerve signals, supporting the idea of rapid molecular changes in learning. This discovery may explain why withdrawal of certain agents can be fatal to patients on respirators.

Sea level rise behind coastal tree deaths

A University of Florida study found that rising sea levels are causing cabbage palms and other coastal trees to die due to saltwater exposure. The phenomenon may be more immediate than thought, with small increases in sea level affecting large areas of flat coastline on the west coast.

New mini microwave thruster is most powerful in its class

Penn State engineers have developed a new mini-thruster that draws only 80 Watts of power but produces more thrust than any system in its class. The thruster uses microwave technology to create a free-floating plasma, which generates thrust when released through a nozzle.

Primitive primate makes the case for Asian anthropoid origins

A 40 million-year-old fossil from Myanmar, Bahinia pondaungensis, sheds light on the origins of anthropoids, a group that includes monkeys and apes. The discovery suggests that these primates may have originated in Asia, rather than Africa, with similarities to tarsiers found in dental anatomy.

Changing approaches to treating gum disease

Researchers are changing treatment methods for gum disease to focus on treating bacterial infections. This approach can save many teeth that were previously considered 'hopeless' and may reduce the risk of heart disease.
