Science and technology continue to change our lives. University of California scientists are tackling the important questions like climate change, evolution, oceanography, neuroscience and the potential of stem cells.

UCTV is the broadcast and online media platform of the University of California, featuring programming from its ten campuses, three national labs and affiliated research institutions. UCTV explores a broad spectrum of subjects for a general audience, including science, health and medicine, public affairs, humanities, arts and music, business, education, and agriculture. Launched in January 2000, UCTV embraces the core missions of the University of California — teaching, research, and public service – by providing quality, in-depth television far beyond the campus borders to inquisitive viewers around the world.

An experimental drug restored brain synapses in two mouse models of Alzheimer’s disease, raising hopes that it could help revive cognitive function in human dementia patients, Yale University researchers report June 1 in the journal Science Translational Medicine.

While much research in Alzheimer’s has centered on reducing levels of beta-amyloid plaque in the brain that is a hallmark of the , recent studies have suggested that immune system response in the brain also plays a role in in patients.

Some scientists now believe that cognitive decline in Alzheimer’s patients results from a loss of synaptic connections between neurons caused by a steady accumulation of beta-amyloid protein in the brain which in turn unleashes a chronic immune system response to the intruder. The end stages of the disease lead to the death of neurons.

One person has died and 22 people have been hospitalized in a listeria outbreak, with most of the infected people having been in Florida about a month before they became sick, the federal authorities said Thursday.

A food source has not been identified as the cause of the outbreak, which has sickened people across 10 states from January 2021 through June 12, 2022, the Centers for Disease Control and Prevention said in a statement.

It typically takes three or four weeks to determine if an illness is tied to an outbreak, so recent cases may not be reported in the data. The true number of sick people is most likely higher because some people recover without medical care, the agency said.
