New Web-Based Tools to Help Food Companies Protect the Food Supply

Our economy, livelihood and wellbeing depend on food and its supply chains. Supply chains may break if a natural disaster destroys a crop in its primary production region, or if someone tampers with food to cause harm or raise profits. In such cases we need to find out quickly about these incidents and find alternative sources of food ingredients and supplies.

With $3 Million Grant, Researchers Hope to Help Find Sites to Grow Tomorrow’s Produce

NIFAGrant-crops-asseng071917.jpg

University of Florida researchers are sounding a warning bell that fresh produce may be hard to come by in the future. Scientists with the UF Institute of Food and Agricultural Sciences cite changes in our climate, loss of fresh water and competition for resources as major threats in farmers’ ability to increase production of fruits and vegetables.

UC San Diego scientists will study an innovative research technique as a way to control disease-causing mosquitoes. The project, which will receive up to $14.9 million, will focus on a technique known as gene drive, which can spread desirable genes in wild populations and suppress harmful organisms.

Scientists Calculate Total Amount of Plastics Ever Produced

Humans have created 8.3 billion metric tons of plastics since large-scale production of the synthetic materials began in the early 1950s, and most of it now resides in landfills or the natural environment, according to a study published today in the journal Science Advances.

Toward 20-Story Earthquake-Safe Buildings Made From Wood

20170714-331DSC_7387UCSanDiegoPublications_ErikJepsencopy.jpg

-- A two-story wooden structure endured four different earthquake simulations on July 14, 2017 on the world’s largest outdoor shake table here in San Diego. And it’s still standing before more tests in the coming weeks. The goal of the tests is to gather enough data to design wood buildings as tall as 20 stories that do not suffer significant damage during large earthquakes. That is, not only can occupants leave the building unharmed, but they can come back and resume living in the building shortly after a temblor.

Artifacts Suggest Humans Arrived in Australia Earlier Than Thought

A team of researchers, including a faculty member and seven students from the University of Washington, has found and dated artifacts in northern Australia that indicate humans arrived there about 65,000 years ago — more than 10,000 years earlier than previously thought.

Scientists Identify New Way Cells Turn Off Genes

For some developmental genes one allele must stay silent, otherwise debilitating syndromes and cancers can arise. HHMI Investigator Yi Zhang and his colleagues have uncovered a new imprinting mechanism cells use to keep these genes quiet in mice.

Scientists Identify New Epigenetic Mechanism That Switches Off Placental Genes in Mice

Harvard Medical School researchers have discovered a new regulatory mechanism for genomic imprinting, the process that silences one parent’s gene so that only the other parent’s gene is expressed in offspring.
