Cracking the Pistachio Genome: A More Nutritious, Climate-Resilient Future

2025-07-31

Researchers at UC Davis have sequenced the most comprehensive pistachio genome to date, paving the way for improved varieties. This detailed genetic map, akin to upgrading from a hand-drawn map to a Google Earth satellite image, allows breeders to develop more nutritious pistachios and helps farmers manage their crops more sustainably in the face of climate change. The study also outlines four key stages of nut development, aiding in optimized water management and reducing pest and disease issues. The improved understanding of gene pathways influencing nutritional value, like protein and unsaturated fatty acid accumulation, promises even healthier pistachios in the future.

Disposable Vapes Release Toxic Metals at Alarming Rates

2025-06-25

A study from UC Davis reveals that some disposable e-cigarettes and vape pods release significantly higher amounts of toxic metals, such as lead, nickel, and antimony, than traditional cigarettes and older e-cigarette models after a few hundred puffs. One disposable device released more lead in a day's use than almost 20 packs of traditional cigarettes. Researchers found that these toxins are either present in the e-liquid or leach from components into the e-liquid, ultimately transferring to the vapor. The high levels of these metals, exceeding health risk thresholds for cancer and other illnesses, highlight the urgent need for stronger regulations and enforcement, especially given the popularity of these devices among teens and young adults who are particularly vulnerable to lead exposure. The findings underscore the potentially severe health consequences, exceeding those of traditional cigarettes in some cases.

Citizen Science Data Reliably Captures Bird Migration Patterns

2025-04-23

A new study shows that citizen science data from iNaturalist and eBird reliably captures known seasonal patterns of bird migration in Northern California and Nevada. Researchers combined data from both platforms, finding similar seasonal patterns for over 97% of bird species, even though the platforms differ in their target users and data collection methods. This study demonstrates the value of citizen science project data, showing that data from different observers and project structures can be integrated to address broad scientific questions.
