Electronic devices are becoming smaller, more connected, and more powerful; and they still have one thing in common: they need energy to function. Even miniature implantable medical devices and remote Internet-of-Things sensors need some amount of power to run, making it a challenge to design equally small, efficient, and durable batteries for them.


One of the alternatives that could potentially be the answer to these problems is the “betavoltaic cell.” These cells are a type of power source akin to photovoltaic cells that, instead of producing an electric current by capturing visible or ultraviolet light, creates electricity using a type of radiation (beta decay) generated internally by a radioactive material. The biggest issue with existing betavoltaic cells is their low conversion efficiency. This means that only a

executive’s appointment signals Frontier’s ambitions to keep growing if federal and state regulators approve its reorganization plan. A federal judge last month approved a plan that could move the business out of bankruptcy by early 2021.

Frontier filed for bankruptcy protection in April to implement a prearranged $10 billion debt-cutting proposal backed by bondholders. Those bondholders named Mr. Stratton a board observer in May and picked him for the executive chairman seat. The appointment is expected to become effective once the Norwalk, Conn., company completes its trip through bankruptcy.

Frontier’s reputation among customers has suffered in recent years as its network of digital subscriber lines failed to deliver the data rates

‘Help us out’: Brother of woman found dead in Chula Vista street pleads for answers

CHULA VISTA, Calif. — The brother of a woman found dead in Chula Vista is pleading for anyone with information to come forward after she was discovered lying in the road not far from her home overnight.

Just before 12:30 a.m. Thursday, a resident called 911 to report they had found a body near Shasta and 2nd streets, Chula Vista police said.

The woman was found naked and with injuries to her head, according to Lt. Dan Peak. Police described her death as “suspicious,” but released no other information about clues that might help explain the disturbing circumstances.

While they confirmed that she is a resident of Chula Vista, officials did not release the woman’s name. A man approached FOX 5 at the scene later that afternoon and identified himself the victim’s brother.

Daniel Rodriguez said it was his younger sister, Laura — the only girl in his family of
