A University of Florida economist is optimistic that the US International Trade Commission will grant relief to US growers hit hard by surging imports of tomatoes and peppers from Mexico. The commission's six-member committee will vote on July 2, with potential remedies including increased tariffs and quotas.
Researchers at the Weizmann Institute have discovered an enzyme called MACH that triggers cellular self-destruction in autoimmune disorders like juvenile diabetes and multiple sclerosis. This finding may lead to treatments that selectively block abnormal cell death signals while allowing normal cell suicide processes to continue.
Researchers at the University of Cincinnati are testing a new portable computer monitoring system to predict changes in traffic flow and traffic delays in real time. The goal is to warn drivers about long delays before they reach a construction zone, giving them time to exit an interstate and use an alternate route.
A new study found that men who smoked light were two-thirds less likely to get prostate cancer if they ate medium to high levels of beta carotene. Heavy smokers received a 50% reduction in risk when consuming high levels of dietary beta carotene.
A new study by Johns Hopkins Medicine reveals that testosterone replacement therapy may improve visual and spatial skills, as well as verbal fluency and memory in men with low testosterone. The findings suggest a potential role for testosterone in cognitive function and brain function.
A new study found that in women, depressive symptoms can predict subsequent alcohol problems over time. Conversely, in men, drinking issues are more likely to lead to depression after three years. This longitudinal study, based on 986 adults, highlights the importance of monitoring both conditions.
A new DNA polymerase, dubbed zeta, allows yeast cells to replicate damaged DNA, increasing their odds of survival but also the risk of mutations. This enzyme is a last-gasp option for cells when all attempts to fix damaged DNA have failed, and its discovery sheds light on how organisms cope with this constant problem.
