The specifics of health care are proving divisive among physicians who otherwise support the Democratic Party.

Wayne Goldner is a staunch Democrat who has penned op-eds criticizing conservative health care laws for threatening coverage for preexisting conditions. “Universal health care is a human right, and it should not bankrupt a family to have an illness,” he says, while attending a New Hampshire primary event for California Rep. Eric Swalwell. Yet after having led a medical practice in Nashua for 35 years, the OB-GYN doesn’t understand the plans being bandied about by many liberal presidential hopefuls. “My litmus test is that if a candidate wants ‘Medicare for All,’ then they are too stupid to understand the complexities of the medical care system,” he adds.

As Democratic contenders have raced to the left to attract their base, with many of them endorsing Medicare for All and even a single-payer system, there are some within the rank and file — particularly medical professionals like Goldner — who are less excited. And while universal health care has become a nearly universal plank within the party, the much more complex question of how to get there is far from settled among these voters. That divide is now beginning to find reflection in the positions adopted by Democratic presidential candidates as they prepare for primary debates starting in August.

Turkish-born engineering guru Ozgur Sinanoglu believes he and his team have created a chip that’s tamper-proof.

Ozgur Sinanoglu is obsessed with computer chips — a passion born at age 10 when his father brought home a Commodore 64. Now 42 and the associate dean of engineering at New York University Abu Dhabi, Sinanoglu claims that he and his colleagues have designed an unhackable chip. Given last year’s Meltdown and Spectre — security flaws that researchers are calling catastrophic because they could affect nearly every computer chip manufactured in the past 20 years — producing a chip capable of repelling attacks would restore peace of mind to everyone from government agencies to private companies.

Whether you crave a Le Creuset pot or a live sheep, these savings clubs will help you save for it.

Eleven times a year, from January to November, Amelia Mxunyelwa, a domestic worker from Cape Town, and five other women from her church contribute R350 ($25) each to their stokvel, putting the money in a bank account that’s held in two of the members’ names. At the beginning of December, the women withdraw the year’s savings and all six of them go on a pre-Christmas shopping spree. They buy in bulk: six 22-pound bags of sugar, six 22-pound bags of mielie meal, six 24-packs of beef stock, six live sheep. “It’s nice to save in this way,” says Mxunyelwa, who has tried and failed “many times” to save on her own. With a stokvel “you have no choice,” she explains.
