Sunflowers face the rising sun because increased morning warmth attracts more bees and also helps the plants reproduce more efficiently, according to a study by researchers at the University of California, Davis. The results were published Aug. 9 in New Phytologist.

“It’s quite striking that they face east,” said Stacey Harmer, professor of plant biology in the UC Davis College of Biological Sciences and senior author on the paper. “It’s better for them to face east, as they produce more offspring.”

We watch a ball as it falls into our glove. We hear a strange sound in another part of the house and listen intently. In neuroscience, the act of narrowing our senses in response to an environmental event is called “attention,” and it is understood that when we attend to a stimulus, we lose the ability to focus on other surrounding inputs.

Think of chromosomes as nature’s shoelaces. Built from DNA, these thread-like structures carry and ferry the genetic information necessary for life. To maintain genetic integrity, chromosomes possess protective structures located at their ends called telomeres. These telomeres are like the plastic tips of shoelaces, preventing the genetic thread from unraveling as cells continuously divide.

Drought can have a lasting impact on the community of microbes that live in and around roots of rice plants, a team led by UC Davis researchers has found. Root-associated microbes help plants take up nutrients from the soil, so the finding could help in understanding how rice responds to dry spells and how it can be made more resilient to drought. The work was published July 22 in Nature Plants.

A team of scientists from UC Davis and Rice University are starting small as they begin to figure out how to build an artificial brain from the bottom up.

Celina Juliano, an associate professor in the Department of Molecular and Cellular Biology, and Jacob Robinson of Rice University’s Brown School of Engineering have won a $1 million Keck Foundation grant to advance the team’s synthetic neurobiology effort to define the connections between neurons and muscles that drive programmed behaviors in living animals.

A new study by UC Davis researchers confirms the low likelihood that SARS-CoV-2 contamination on hospital surfaces is infectious. The study, published June 24 in PLOS ONE, is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs. 

The deep ocean is home to many strange looking fish and other animals. A new study shows that the cold, dark depths of the ocean contain a wider variety of body shapes for fish than shallower waters. That supports the idea that the deep ocean is a hotspot of evolution for fishes.

In April of this year the Vertebrate Genomes Project (VGP) announced their flagship study including high-quality, near error-free, and near complete reference genome assemblies for 16 species representing six major lineages of vertebrates, including mammals, reptiles, monotremes, amphibians and fish.

While drugs help patients mitigate the most extreme conditions of mental illnesses like schizophrenia or depression, they often don’t address the cognitive deficits many diseases cause, such as memory loss, low attention span and impaired decision-making.

Mechanical and aerospace engineering (MAE) professor Steve Robinson, assistant professor Jonathon Schofield, and Neurobiology, Physiology and Behavior (NPB) associate professor Wilsaan Joiner are teaming up in a new four-year, $1.3 million NASA-funded project to study different visual and haptic strategies to help astronauts more safely and precisely operate ro
