UT mathematician develops model to control spread of aquatic invasive species

A mathematical model has been developed to predict how invasive species spread in rivers and how to control their movement using optimal water flow rates. The study, published in Mathematics, uses a partial differential equation model to illustrate how adjusting the water flow rate can prevent invasive populations from expanding upstream.

Eastern equine encephalitis virus poses emergent threat, say NIAID officials

Eastern equine encephalitis virus is a deadly mosquito-borne illness that has existed for centuries, with a particularly deadly year in the US in 2019. Current research efforts focus on developing vaccines and treatments, but challenges include limited funding and difficulties in reaching target populations.

Not so selfish after all--Key role of transposable elements in mammalian evolution

A study published in Nucleic Acids Research reveals that transposable elements have been co-opted by hosts to provide useful functions, such as encoding part of a host protein. The research found tens of thousands of potentially co-opted TE sequences, which are more conserved across species and suggest a key role in mammalian evolution.

Survey finds 1 in 3 patients needed more information on cancer treatment side effects

A nationwide survey of over 400 US adults with cancer found that nearly all patients felt confident in their treatment decisions but had gaps in knowledge about potential side effects. The study highlights the need for more informed patient counseling and coordination between oncology disciplines to manage treatment-related side effects.

Leadership's in the blood for tiny fish

Research on Trinidadian guppies reveals that leadership tendencies are partly inherited, with around a third of the variation explained by pedigree. Males bred for high leadership exhibit lower aggression and increased sociability compared to those bred for low leadership. In contrast, female leadership does not appear to be linked to ...

The cause of chewy chicken meat

University of Delaware researchers identify gene expression irregularities and lipoprotein lipase enzyme as causes of wooden breast syndrome in broiler chickens. This metabolic disorder can make the meat hard and chewy, causing significant economic losses for growers.

Machine, meet stem cells

Scientists at Gladstone Institutes used a machine-learning approach to discover new ways of controlling the spatial organization of induced pluripotent stem cells. The model predicted patterns that could lead to the creation of functional organs for research or therapeutic purposes, and was found to be correct in simulating desired arr...

Outback telescope captures Milky Way center, discovers remnants of dead stars

A radio telescope in the Western Australian outback has captured a new view of the Milky Way's centre, revealing remnants of 27 massive stars that exploded as supernovae. The data comes from the GaLactic and Extragalactic All-sky MWA survey, which used low-frequency radio waves to map the sky.
