The making of soldier ants

Scientists at McGill University found that a rudimentary 'organ' in ants regulates the balance between soldiers and workers, allowing colonies to maintain a constant ratio. By controlling the growth of this organ, ants can rapidly produce more soldiers when needed.

Boxing up ag field nitrogen

Saturated riparian buffer strips can effectively reduce nitrate loads into nearby streams and lakes by reconnecting water flow through the soil, allowing growers to continue using tile drains. The system's cost per pound of nitrate removed is $1.33 for a 40-year lifetime, making it a simpler and cheaper alternative to other systems.

Cancer patients with rare deadly brain infection treated successfully with off-the-shelf adoptive T-cell therapy

A Phase II clinical trial found marked improvement in three patients with progressive multifocal leukoencephalopathy (PML), a rare and often fatal brain infection. Patients infused with donor T cells targeting the BK virus experienced significant reductions in JC viral load and clinical improvement.

Creating custom brains from the ground up

Researchers at Boston Children's Hospital have developed a new method to create customized mouse models for studying the brain. This technique involves using a natural toxin to kill off developing brain cells, allowing scientists to reconstitute the forebrain from genetically engineered stem cells. The resulting mice have tightly contr...

Mount Sinai builds modeling systems identifying gene-drug and environment interaction

A new approach integrates genomic and temporal information to infer causal relationships between genes, drugs, and their environment, allowing for a more accurate prediction of their interactions over time. The tool demonstrates the improvements in inferring genetic causes of disease enabled by higher-resolution molecular profiling.

Tracking a killer

UCSB, UCSD, and SBP researchers developed a method to track sepsis development on a molecular level, revealing different pathways depending on host responses to various pathogens. Boosting anti-inflammatory activity or blocking TLR-4 activation showed potential as therapeutic approaches.

Reconstructing the history of mankind with the help of fecal sterols -- first test on the Maori

Researchers at Ca' Foscari University of Venice identified and dated traces of sterols in Lake Diamond and Kirkpatrick sediments, proving the presence of the Maori people. The study demonstrates a method for reconstructing human history by analyzing fecal sterols, which also shows the impact of the Maori population on the native forest.

The culprit of superconductivity in cuprates

Researchers at Harvard John A. Paulson School of Engineering and Applied Sciences found that a strong chemical bond between the apical cation and oxygen in cuprate compounds impacts superconductivity temperature. This discovery sheds light on key component of complicated phenomena in cuprates, opening up new avenue for materials design.

Study identifies gene that makes gentle touch feel painful after injury

Researchers identified PIEZO2 as a gene controlling tactile allodynia, a form of pain caused by gentle touch after injury. The study found that PIEZO2 plays an essential role in the nervous system's reaction to injury and inflammation, making it a target for developing precise treatments for relieving painful skin injuries.
