Biologists use computers to study bacterial cell division

Researchers created a mathematical model of bacterial cell division in Caulobacter crescentus, confirming existing hypotheses and identifying gaps in understanding. The model demonstrates the role of computation in biology and provides a framework for testing predictions and simulating mutant bacteria.

Between water and rock -- a new science

Scientists are discovering that aquatic nanoparticles influence natural and engineered water chemistry differently than similar materials of a larger size. The review considers nanoparticles formed by natural processes in water and as unintended consequences of human activity, such as mining or water treatment.

HARDY rice: less water, more food

Scientists have developed a new type of rice that grows better and uses water more efficiently than other rice crops. The HARDY gene improves key features of the grain crop, leading to increased biomass under both drought and non-drought conditions.

Study reveals predation-evolution link

Researchers found a correlation between predation intensity and global marine biodiversity, with increased predation rates preceding changes in armor morphology. The study suggests that ecological interactions may drive evolution, with predators driving diversity through drilling and repair scars.

Virginia Tech faculty members earn IBM awards

Faculty members Kirk Cameron, Wu-Chun Feng, and Dimitrios Nikolopoulos have received IBM Faculty Awards for their exceptional work in plant phylogeny, software productivity, and computing environments. The awards aim to promote collaboration between researchers and foster growth in strategic disciplines.

Fat horses face health problems

A study conducted by Virginia Tech researchers found that 51% of evaluated horses were overweight or obese, posing serious health problems like laminitis and hyperinsulinemia. The study suggests changes in horse care practices can help mitigate these risks.

Light-activated therapy targets DNA components

Researchers at Virginia Tech have introduced a DNA targeting component in light-activated molecular systems, allowing for more selectivity in attacking cancer cells. The new system uses visible light to signal the synthesized bioactive molecules to cleave DNA, reducing damage to healthy tissue.
