Researchers uncover new biological target for combating Parkinson's disease

Researchers have identified a new biological target for combating Parkinson's disease by discovering a compound that eases symptoms in mice. The study found that a protein called AIMP2 activates a self-destruct pathway, leading to cell death, but also triggered the activation of PARP1 and PAR, which can be targeted by existing compounds.

Mercury levels in Pacific fish likely to rise in coming decades

Researchers have solved the mystery of how mercury enters open-ocean fish, finding that up to 80% is produced deep in the ocean by bacteria. Mercury levels are likely to rise in Pacific fish over the coming decades due to increased industrialization in Asia.

Scientists analyze the extent of ocean acidification

A new study by Alfred Wegener Institute researchers analyzed data from over 150 species, finding that most animal groups are affected negatively by higher carbon dioxide concentrations. Corals and echinoderms react sensitively to ocean acidification, while crustaceans may be more resilient in certain scenarios.

Epilepsy drug dosage linked to specific birth defects

A new study has found a link between high doses of epilepsy medication valproate and increased risk of physical birth defects such as spina bifida and hypospadias in babies. Reducing the dose of valproate during pregnancy can significantly lower this risk, providing pregnant women with epilepsy new hope.

Study provides strongest clues to date for causes of schizophrenia

A new genome-wide association study has identified two major pathways involved in causing schizophrenia, including a calcium channel pathway and a micro-RNA 137 pathway. The study, published in Nature Genetics, provides the strongest clues to date for understanding the causes of this debilitating mental illness.

Ocean fish acquire more mercury at depth

Researchers found that photochemical reactions break down mercury at the surface, but it's converted to its toxic form at deeper depths. This process affects ocean fish and the human seafood supply, with implications for reducing mercury emissions.

Researchers find essential brain circuit in visual development

A study in mice reveals an essential brain circuit that helps dictate how the eyes connect to the brain, which could lead to new treatments for amblyopia. The research found that manipulating a specific brain circuit can prevent ocular dominance in young mice and induce it in older mice beyond the critical period.

Gallo Center study in mice links cocaine use to new brain structures

Research suggests cocaine use may lead to continued drug seeking by stimulating growth of new brain structures associated with learning and memory. The study used live brain imaging to observe mice given cocaine or saline, finding significant increases in dendritic spines after two hours.

Cocaine's effect on mice may explain drug-seeking behavior

Researchers found that cocaine exposure leads to rapid growth of new dendritic spines in the frontal cortex, enabling mice to strongly prefer drug cues over other stimuli. This study sheds light on the brain's role in drug-seeking behavior and may inform strategies for tackling addiction.
