California aims to quintuple its coronavirus testing
California plans to significantly ramp up its coronavirus testing and tracing efforts, as the state strives to reach a point where it could relax stay-at-home rules implemented to contain the outbreak.
During a press conference on Wednesday, Gov. Gavin Newsom said the state intends to increase testing capacity from about 16,000 per day to 25,000 by April 30, and reach between 60,000 and 80,000...
USGS releases first-ever comprehensive geologic map of the Moon
Have you ever wondered what kind of rocks make up those bright and dark splotches on the moon? Well, the USGS has just released a new authoritative map to help explain the 4.5-billion-year-old history of our nearest neighbor in space.

New dual-action coating keeps bacteria from cross-contaminating fresh produce
Over the course of their journey from the open fields to the produce displays at grocery stores, fresh vegetables and fruits can sometimes become contaminated by microorganisms. These items can then spoil other produce, spreading the contamination further and increasing the number of food items that can cause illnesses.
Digital agriculture paves the road to agricultural sustainability
In a study published in Nature Sustainability, an ecosystem scientist and an agricultural economist outline how to develop a more sustainable land management system through data collection and stakeholder buy-in.
Caribbean coral reef decline began in 1950s and 1960s from local human activities
Not long ago, the azure waters of the Caribbean contained healthy and pristine coral reef environments dominated by the reef-building corals that provide home to one-third of the biodiversity in the region.

Despite longstanding popular belief, bicycle lanes can actually improve business. At worst, the negative impact on sales and employment is minimal, according to a new study. Researchers studied 14 corridors in 6 cities -- Portland, Seattle, San Francisco, Memphis, Minneapolis and Indianapolis -- and found such improvements had either positive or non-significant impacts on sales and employment....

Human-caused warming will cause more slow-moving hurricanes, warn climatologists
- ScienceDaily
- 20/4/22 21:13
Hurricanes moving slowly over an area can cause more damage than faster-moving storms, and rising global temperatures will likely cause more mid-latitude hurricanes to slow down, said a team of climatologists. They used a large ensemble of climate simulations to explore the link between anthropogenic climate warming and hurricane movement speed.
Tectonic plates started shifting earlier than previously thought

- 20/4/22 21:13
Scientists examining rocks older than 3 billion years discovered that the Earth's tectonic plates move around today much as they did between 2 and 4 billion years ago. The findings suggest that the continents settled into place and sustained life much earlier than previously thought, and give insights into plate tectonics on other planets.

Despite the importance of sweet potato, little is known about the sweet potato microbiome.
Disappearing Alaskan sea ice is significant for Arctic marine ecosystem
- ScienceDaily
- 20/4/22 21:11
A new study shows that plant materials originating in Arctic sea ice are significantly incorporated into marine food webs that are used for subsistence in local communities of the greater Bering Strait region. The research has the potential to demonstrate the importance of sea ice ecosystems as a source of food in Arctic waters in Alaska and beyond.
More protections needed to safeguard biodiversity in the Southern Ocean

Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new study.
New systematic review captures what makes a positive post-birth experience for new mothers

A new qualitative systematic review conducted to inform the scope of a new World Health Organization (WHO) post-birth (postnatal) guideline identifies four clear themes for a positive experience in mothers across 15 different countries and cultures.
Human-caused warming will cause more slow-moving hurricanes, warn climatologists
Hurricanes moving slowly over an area can cause more damage than faster-moving storms, because the longer a storm lingers, the more time it has to pound an area with storm winds and drop huge volumes of rain, leading to flooding. The extraordinary damage caused by storms like Dorian (2019), Florence (2018) and Harvey (2017) prompted Princeton's Gan Zhang to wonder whether global climate change...
Scientists invent nanoparticle that could improve treatment for bone defects
A team of biomaterials scientists and dentists at the UCLA School of Dentistry has developed a nanoparticle that, based on initial experiments in animals, could improve treatment for bone defects.

A new study shows that plant materials originating in Arctic sea ice are significantly incorporated into marine food webs that are used for subsistence in local communities of the greater Bering Strait region.
Tectonic plates started shifting earlier than previously thought
An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some researchers theorize it happened around four billion years ago, while others think it was closer to one billion.
More protections needed to safeguard biodiversity in the Southern Ocean
Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new CU Boulder study published today, Earth Day, in the journal PLOS ONE.
Sweet potato microbiome research important first step towards improving yield
Grown around the world, sweet potatoes are an important source of nutrition particularly in sub-Saharan African and Asian diets. Sweet potatoes are especially significant to sub-Saharan Africa as a source of Vitamin A, a nutrient commonly deficient in the region. While China currently produces the most sweet potatoes by country, sub-Saharan Africa has more land devoted to sweetpotatoes and...
Study finds bike lanes provide positive economic impact
Despite longstanding popular belief, bicycle lanes can actually improve business. At worst, the negative impact on sales and employment is minimal, according to a new study from Portland State's Transportation Research and Education Center (TREC).
New design could make fiber communications more energy efficient
Researchers say a new discovery on a U.S. Army project for optoelectronic devices could help make optical fiber communications more energy efficient.
