Up until this week, the San Diego Police Department has broadcast police calls on an open channel. It’s been a resource for people who follow crime and monitor the police. But some say it has its drawbacks. “In the past we were not encrypted, which meant that by using police scanners anyone in the public, the media, etc. could listen in on all of our radio communications,” said San Diego Police Lt. Daniel Meyer.

In a lab at the UC San Diego School of Medicine a computer screen shows a video of a human lung with a form of fibrosis. Some parts of it have been dyed green and blue, with the deceased section in red. But this isn’t really a lung. It’s a very small model, made from human stem cells, and it’s called an organoid. “We now have a way to screen the drugs on this, to reverse this exact condition,” Professor Pradipta Ghosh said as she pointed at the screen.

When I met William Pink he was wearing a grey hoodie and a crushed hat that was lined with small pins. He held a stick with a string attached to the far end, and the string held a row of wooden rings. “This is an acorn ring game,” he said. “These are the acorn caps from the interior white oak. And the idea of the game is to catch the rings.”He tossed the row upward and a ring came down, impaled on his stick. “Got one,” he said.

About 10 years ago, Ana Moreno was a PhD student at UC San Diego when she had a free Sunday night and did what some serious students do. She started reading science papers. “I came across a paper that talked about these people in Pakistan, street performers, who could walk on fire and do different performances with no pain whatsoever," Moreno said.

On Friday volunteers and City of San Diego work crews planted trees in Colina del Sol Park and along nearby streets for Arbor Day. This week also marked another milestone in the beautification of San Diego’s right of ways. The community of Bay Park saw the city complete its undergrounding of power lines. The month before, the Rolando neighborhood was finished. Power lines and poles that remain a common site are a historic architecture that nobody wants to preserve.

Plant biologist Lena Mueller emerges from a brightly-lit room in a Salk Institute lab, holding a small plant rooted in a very small container of soil. “This is our little legume that we work with and it looks very sad here because we don’t give it a lot of nutrients because we want it to interact with the fungus,” Mueller said. But when fungus and plant interact, that’s when the plant gets a lot happier.

A bipartisan federal commission has called the engineering of biological systems the next transformative leap for human potential. This includes discovering new medicines, creating hardy, fruitful plants and manufacturing products based on organic structures. But the National Security Commission on Emerging Biotechnology said in its new report that the government’s approach to research lacks coordination and needs better leadership.

Ephedra. Artemisia. Yerba santa. Opium poppy. A lot of well-known drugs start with roots in the ground. The San Diego Botanic Garden in Encinitas is leading an effort to make curative plants even better by exploring their genomes. The Medicinal Plants Initiative began three years ago by the botanic garden. During that time, their collection of medicinal plants has quadrupled, according to Benjamin Naman, director of medicinal plants research.

A campground at the Tijuana River Valley Regional Park is set to reopen as planned on Tuesday after being closed for more than a year, despite a push by a local union to keep it closed. The SEIU Local 221, which represents park rangers, argued the area was so polluted it posed a danger to the health of people using the park or working there. The campground is home to a cluster of yurts that offer a temporary home to visiting campers.

Our most familiar image of the dung beetle shows one of them rolling a finely shaped ball of dung to a hiding place where it digs a hole and lays its eggs. Along with the dung ball rollers, there are the “dwellers” that move into a dung pile and set up housekeeping. “And there’s a third group that are called tunnelers. And they tunnel underneath cow pats, and create little brood chambers in these tunnels.
