Brain state affects memory recall

New research from UC Davis found that high theta waves before recalling a memory are associated with better performance, contradicting the assumption that the brain waits for external stimuli. The study suggests that most of the brain is busy with internal activity unrelated to the outside world.

Hydrocarbons in the deep Earth

A computer modeling study published in PNAS reveals that methane molecules can combine to form larger hydrocarbon molecules under high temperatures and pressures of the Earth's upper mantle. This finding has significant implications for understanding carbon reservoirs and fluxes in the Earth.

Immune molecule regulates brain connections

A recent study published in Nature Neuroscience reveals a potential link between immunity, infectious disease, and conditions such as schizophrenia and autism. Researchers found that an immune molecule called Major Histocompatibility Complex type 1 (MHC type I) regulates brain connections during early postnatal development.

AAAS news briefs from UC Davis

Researchers at UC Davis are presenting innovative solutions to reduce greenhouse gas emissions from the transportation sector, including electrification of vehicles and producing biofuels. The university is also exploring celestial superfluids, which offer potential breakthroughs in materials science and technology.

Plants cloned as seeds

Researchers have successfully cloned plants as seeds, paving the way for hybrid crop plants that can breed true. The breakthrough uses a process called apomixis, where eggs and sperm are haploid, allowing diploid eggs to be produced without sexual recombination.

Popular kids more likely to bully peers

A new study finds that popular adolescents, particularly those in the second tier of popularity, are more likely to engage in bullying behavior. The researchers argue that social status and aggression are linked, with students who occupy the center of the social hierarchy wielding power and potentially deterring retaliation.

Where unconscious memories form

A study published in Neuron found that the perirhinal cortex plays a crucial role in forming unconscious conceptual memories. Researchers used functional magnetic resonance imaging (fMRI) scans to map brain activity while participants performed memory tests, revealing that damage to this area impairs memory formation.

UC Davis study: Wild salmon decline was not caused by sea lice from farm salmon

A new UC Davis study concludes that sea lice from salmon farms have no significant impact on the productivity of wild pink salmon populations. The research analyzed 10 years of farm fish counts and 60 years of wild fish counts, contradicting earlier reports linking farm salmon to the 2002 population crash in western Canada.

Plant clock gene also works in human cells

Researchers identified a plant clock gene that works in human cells and vice versa, with similar function. The study suggests convergent evolution as the explanation for this phenomenon, highlighting the importance of maintaining accurate circadian rhythms in both plants and humans.

New DNA repair pathway

UC Davis researchers have identified a new inducible pathway for repairing DNA damaged by oxygen radicals, which could lead to a better understanding of the causes of some cancers. The discovery involves an enzyme called NEIL1 that detects and repairs aberrant bases before changes in the genome become permanent.

Understanding diabetes at the molecular level

Scientists have identified a crucial protein complex called TORC 2 that plays a significant role in insulin signaling and is linked to both diabetes and cancer. The study found that activating this complex is essential for cells to take up sugar from the blood, and that it may hold potential as a new target for treating type II diabetes.

Low elevations hold climate surprises

A new study reveals climate change impacts low-elevation mountain plants more significantly than expected, with increased drought stress observed in forests below 4,000 feet. The findings inform local conservation strategies by predicting biological responses to climate change.
