Members of the medical and hacker communities are raising concerns about cybersecurity vulnerabilities affecting medical records, infrastructure and devices.
Experts have long warned of security flaws in medical devices — insulin pumps that can deliver deadly doses, for example. Many devices include wireless connectivity capability.

Doctor-Hackers Raise Awareness Of Medical Device Vulnerabilities
Stable, nontoxic refrigerants changed the world, transforming food storage, expanding Sun Belt populations, even helping early movie theaters succeed. But they also wrecked the ozone layer — Earth’s shield against harmful ultraviolet radiation.
Today, as stockpiles dwindle — and prices rise — due to phase-outs set by the Montreal Protocols 30 years ago, the future of Freon and its successors remains in doubt.

As Stockpiles Dwindle, Freon Prices Rise
Every six months, the Palo Verde Nuclear Generating Station southwest of Phoenix, Arizona shuts down one of its three reactors for refueling and maintenance.
Join me in this feature-length venture into the belly of the beast, from the storage casks to the open reactor itself.

A 200-mile lightning flash and another flash lasting nearly eight seconds have redefined experts’ notions of what is possible for such events.
The new data prompted a World Meteorological Organization committee to recommend revising the definition of lightning discharges.

In 1928, the equations of British physicist Paul Dirac helped to describe the workings of the subatomic particles known as fermions. Within a year, other theorists – including a contemporary and schoolmate of Einstein’s named Hermann Weyl – had come up with solutions to Dirac’s equations that meant two other, quite odd types of fermions might also exist.
Proving them right would take some time, and Weyl’s quasiparticle assumed a kind of legendary status until 2015, when three separate teams confirmed its existence (my article says two, but a third popped up after I wrote it). Read on to find out more about this “ghost particle” and how it could transform electronics.
