Invasive mosquito known for dengue, yellow fever found in Antioch
An invasive mosquito has been found in Antioch, the Contra Costa Mosquito and Vector Control District said Friday. The species, Aedes aegypti, is capable of transmitting pathogens that can cause Zika virus, dengue fever, and yellow fever. The species was found in an area of Antioch where the district also found invasive mosquitoes last fall. District employees recently re-inspected locations where the mosquitoes were previously found. A sample taken this week from one of those properties contained young mosquitoes developing in the water and one recently emerged adult. The district said in a statement it will likely find more of these mosquitoes as it inspects more properties. An Aedes aegypti mosquito is pictured at a laboratory of the Center for Parasitological and Vector Studies (CEPAVE) of the national scientific research institute CONICET, in La Plata, Buenos Aires Province, Argentina, on March 26, 2024. Researchers at CONICET are studying the biology, genetic characteristics and behaviour of the Aedes aegypti mosquitoes, transmitter of dengue, zika and chikungunya, and creating biological control strategies as Argentina is facing a significant growing number of dengue cases.

"Scheduling a district inspection of your front and back yard is strongly recommended, as Aedes aegypti mosquitoes are found in hard-to-find locations." Aedes aegypti mosquitoes are very small, about a quarter-inch, with black bodies and pearly white stripes and spots. They lay sticky eggs above the water line in any size container that holds water, including potted plants or other outdoor containers. Because of their disease risk and their ability to grow from egg to adult in even very small amounts of water, the district said it is critically important that residents work with the district to prevent them from becoming established in the area. The district says to dump out any amount of standing water from any back or front yard container, including buckets, toys, tires, fountains, flowerpot saucers, pet bowls, and that people should report unmaintained swimming pools to the district. It also says people should wear mosquito repellent when outside and report any daytime mosquito biting to the district at (925) 685-9301 or can go to

You Won't Want to Miss March's Partial Solar Eclipse

Credit - Luis Robayo—Getty Images If you missed the blood moon total lunar eclipse on March 13 into March 14, you may have another chance to see an eclipse event later this month. On March 29, people in parts of the Northern Hemisphere will be able to see a partial solar eclipse. Though perhaps not as enticing as the April 2024 total solar eclipse—in which Americans had the opportunity to see the sun fully overtaken by the moon, casting parts of the country in darkness—the partial solar eclipse will allow some viewers to see the moon block up to 93% of the sun, according to Here's what you need to know about the upcoming partial solar eclipse. Similar to a total solar eclipse, during a partial solar eclipse, the moon passes between the sun and the Earth. But unlike a total eclipse, the three celestial bodies are not completely lined up, and thus the moon will only block parts of the sun to viewers on Earth. To those in the eclipse's path, the sun appears somewhat like a crescent. Partial solar eclipses occur, on average, two times per year, according to the Exploratorium Museum in San Francisco, California. The next partial solar eclipse, the first of this year, will occur on March 29. According to NASA, the partial eclipse will have already started by sunrise in the Americas, while in western Europe and northwest Africa, it will begin mid-to-late morning. In eastern Europe and northern Asia, people can witness the eclipse in the afternoon and early evening. The partial solar eclipse in March will cast a shadow across vast portions of the world, though different areas will be able to see different percentages of the sun covered. According to while over 800 million people will be in the path of the eclipse, only 44,800 people will be able to see at least 90% of the sun be covered by the moon. Per NASA, viewers will see a partial solar eclipse in sections of North America, Europe, Africa, northern Asia, small parts of South America, throughout Greenland and Iceland, as well as parts of the Atlantic and Arctic oceans. Some of the spots whereby the eclipse will encounter the largest coverage include Halifax, Canada, where an estimated 83% of the sun will be covered at around 7 a.m. In Portland, Maine, 64% of the sun will likely be covered at around 6 a.m. Meanwhile, in Nuuk, Greenland, 87% of the sun is set to be covered between 8 a.m. and 9 a.m. Since the sun is never fully covered, viewers must always look at a partial solar eclipse while wearing protective glasses. Safe solar viewing glasses are different from normal sunglasses—they tend to be thousands of times darker. Without protective gear, looking directly at an eclipse can cause serious damage or scarring to the eyes. 'Solar retinopathy is a photochemical injury to your retina,' Dr. Nicole Bajic, a surgical ophthalmologist at the Cleveland Clinic, previously told TIME via email. A good place to buy safe solar viewing glasses, that meet the standard necessary to safely view an eclipse event, is through the American Astronomical Society's (AAS) trusted vendor list, Richard Fienberg, project manager at AAS' Solar Eclipse Task Force, told TIME in 2024. 'There are companies selling eclipse glasses under false pretenses. The two most likely false pretenses are the glasses have not actually been tested properly and shown to be safe, or the glasses are made in China but printed with information that says they're made in America,' he said. If you have old glasses from a previous eclipse event, Feinberg said that these may still be usable, but they should be checked for holes and tears to ensure they meet the safety standard. Viewers can also use an indirect viewing method, like a pinhole projector, in order to indirectly see the eclipse occur through shadows, but this must be done with care. Contact us at letters@
