Inventor Beulah Louise Henry’s unstoppable rise to becoming ‘Lady Edison’

Get the Popular Science daily newsletterđź’ˇ Breakthroughs, discoveries, and DIY tips sent six days a week. Beulah Louise Henry was just nine years old when she came up with her first invention in 1896, a device that allowed a man to tip his hat without ever putting down his newspaper.  By her death in 1973, at the age of 85, she’d come up with so many more—a doll with eyes that changed color with the press of a button, a sewing machine without a bobbin (a threaded spool that slowed down work because it had to be frequently refilled), a clock designed to help kids learn to tell time, and others—that the press even dubbed Henry “Lady Edison.”  Her ideas, she once told a reporter, were “messages from a guiding spirit.” Beulah Louise Henry’s early life Henry grew up a daughter of fortune in Raleigh, North Carolina. Her father Walter was a prominent lawyer and orator. Her mother, who was also named Beulah—a common tradition in the late 19th century—was a homemaker and the daughter …

Edison executive pay soars despite devastating Eaton fire

Edison executive pay soars despite devastating Eaton fire

Edison International boosted the pay of its top executives last year despite their responsibility for the safety of the company’s power lines before the devastating Eaton fire, which destroyed a wide swath of Altadena and killed 19 people. Although the company cut cash bonuses for its senior executives, citing the wildfires, their overall compensation went up substantially as the utility’s profit soared in 2025. Pedro Pizarro, chief executive of the parent company of Southern California Edison, received $16.6 million in cash, stock and other compensation last year, up 20% from 2024, according to a new company filing. Steven Powell, president of Southern California Edison, received compensation totaling $6.5 million last year, up from $3.9 million in 2024 — a jump of more than 65%. The utility’s transmission equipment is suspected of igniting two wildfires on Jan. 7, 2025, including the Eaton fire, which left thousands of families homeless. The Times earlier detailed how Edison fell behind in performing maintenance on its aging transmission lines — work that it had told state utility regulators was needed. …

Edison may have unknowingly created graphene with his 1879 light bulb

Edison may have unknowingly created graphene with his 1879 light bulb

According to new research from Rice University, while Edison’s goal was simply to create a longer-lasting electric lamp, the extreme conditions created inside Edison’s carbon filament bulbs in those early light bulbs may have inadvertently produced the same conditions needed to create graphene. The study by James Tour and his former graduate student Lucas Eddy, who was the lead researcher, shows that when the authors recreated Edison’s original incandescent light bulb, they also discovered that the same electrical heating caused by the filament could convert the carbon filament into turbostratic graphene, the name for a type of graphene with loosely stacked atomic layers. Graphene is a single layer of carbon arranged in a two-dimensional honeycomb shape. It is incredibly strong, highly conductive, and transparent. While P.R. Wallace, a physicist in the 1940s, had proposed the theoretical existence of graphene, it was not until the early 2000s that graphene was isolated and characterized by Konstantin Novoselov and Andre Geim, who won the 2010 Nobel Prize in Physics for their work on graphene.
