Cow gene study shows why most clones fail

A new study by researchers from the U.S. and France finds that multiple anomalies in gene expression, including failure to implant and placenta development, contribute to the high rate of pregnancy failure for cloned embryos. The study reveals critical developmental genes and hormonal signaling issues that lead to these failures.

The fate of Neanderthal genes

A new study reveals that Neanderthal genes are being removed from the human genome at a rate of weak but widespread selection. The researchers found that the small population of Neanderthals mixing with modern humans led to inbreeding, causing genetic variants to persist and then be weeded out by natural selection.

Diversity as natural pesticide

Research suggests that increasing plant diversity can limit the nutrient supply for insect pests, reducing their populations. By introducing different genotypes of the same crop species with varying nutrient levels, farmers may be able to control insects while maintaining consistent production.

Drought conditions slow the growth of Douglas fir trees across the West

A study by University of California - Davis researchers found that drought conditions significantly impact Douglas fir tree growth, with warmer and drier conditions causing the most stress. The analysis of tree core samples over a 91-year period indicates projected decline in growth rates under future climate change scenarios.

Sunflowers move by the clock

Researchers at UC Davis discovered how sunflowers follow the sun during the day using their internal clock, affecting growth hormones and flower orientation. The study found two growth mechanisms at work in sunflower stems, one driven by light availability and another controlled by the circadian clock.

Refugees can offer economic boost to their host countries

A recent study by UC Davis and UN World Food Program found that refugees receiving cash aid can create significant economic benefits for their host countries. The researchers discovered that each additional refugee increased local income by up to 96% in one of the camps, with most of this money spent on goods and services outside the c...

UC Davis study says logos make a group seem real

A UC Davis study found that group symbols like logos and flags create the impression of a unified, effective, and cohesive group, even among diverse members. However, this can come at the cost of appearing less inclusive and warm. The research suggests using symbols strategically to achieve desired impressions.

Behind the levees

A recent study by the University of California, Davis, found that levees can actually increase flood risk for up to a third of residential structures and 22% of commercial structures behind them. The research team estimated long-term flood risk, probabilities of levee failure, and resulting economic losses in the Sny Island levee distr...
