Ludwig Cancer research study finds way to revive potent immune cells for cancer therapy

A Ludwig Cancer Research study has discovered how to revive terminally exhausted T lymphocytes, found within tumors, for cancer therapy by using an immune factor called interleukin-10. This revival restores their potent anti-cancer activity, leading to tumor regression and cures in mouse models of melanoma and colon cancer.

Pristine quantum criticality found

A team of physicists from Rice University and colleagues discovered that quantum fluctuations may give rise to topological phases of matter. The study used magnetic susceptibility, specific heat, and inelastic neutron scattering measurements to show that the material CeRu4Sn6 is quantum critical without fine-tuning.

Prebiotic ethanolamine found in space

Researchers found prebiotic ethanolamine in a molecular cloud near the center of our galaxy, suggesting it may have formed in space and was incorporated into meteorites and planetesimals. This discovery supports the idea that the molecule could have contributed to the assembly and evolution of primitive cell membranes on early Earth.

Sustainable funding needed to provide nursery places

Researchers found that children who attended childcare outside the home during COVID-19 made greater gains in language and thinking skills, particularly among those from less advantaged backgrounds. The study recommends sustainable funding for nursery provision, promotion of funded places in target areas, and removal of administrative ...

How hepatitis C virus evades the immune system

Researchers discovered a novel molecular mechanism by which HCV interferes with the host's immune system, leading to chronic infection. The study found that HCV core protein is degraded via SPP and MHC class I proteins, impairing proper immune response and allowing infection to become chronic.

Mapping the local cosmic web

Researchers have created a new map of dark matter in the local universe using machine learning, revealing previously undiscovered filamentary structures connecting galaxies. The map provides a detailed understanding of the distribution of dark matter and its gravitational influence on galaxies.

Is closing the gap working?

A five-year study found that Australia's Closing the Gap program has not improved disparities in Indigenous health, income, employment, child removal, and incarceration. Researchers suggest that 'Western' cultural beliefs over Indigenous cultures hinder policy change.

Identifying how chemotherapy drug works could deliver personalized cancer treatment

Decitabine, used to treat blood cancers like MDS and AML, works by activating endogenous retroviruses that induce an immune response. The study found two key gene sequences involved in this process, Staufen1 and TINCR, whose expression levels determine a patient's response to the drug.

Otago study helps explain how religious beliefs are formed

A University of Otago study found that anxiety enhances recall of supernatural agents, leading to the formation of religious beliefs. The research suggests that anxious individuals are initially attracted to the scary traits of gods and other supernatural concepts due to their alarming effects on our expectations.

Infants recognize rapid images, just like adults

Researchers found that infants aged 7 and 8 months could identify two faces when the temporal interval was 800ms, but overlooked the second face when separated by 200ms. This suggests that infants take less than a second to process visual information and have the same temporal limitation as adults.
