In the urgent quest for a more sustainable global food system, livestock are a mixed blessing. On the one hand, by converting fibrous plants that people can’t eat into protein-rich meat and milk, grazing animals like cows and sheep are an important source of human food. And for many of the world’s poorest, raising a cow or two—or a few sheep or goats—can be a key source of wealth.

But those benefits come with an immense environmental cost. A study in 2013 showed that globally, livestock account for about 14.5 percent of greenhouse gas emissions, more than all the world’s cars and trucks combined. And about 40 percent of livestock’s global warming potential comes in the form of methane, a potent greenhouse gas formed as they digest their fibrous diet.

That dilemma is driving an intense research effort to reduce methane emissions from grazers. Existing approaches, including improved animal husbandry practices and recently developed feed additives, can help, but not at the scale needed to make a significant global impact. So scientists are investigating other potential solutions, such as breeding low-methane livestock and tinkering with the microbes that produce the methane in grazing animals’ stomachs. While much more research is needed before those approaches come to fruition, they could be relatively easy to implement widely and could eventually have a considerable impact.

CDK Global touts itself as an all-in-one software-as-a-service solution that is "trusted by nearly 15,000 dealer locations." One connection, over an always-on VPN to CDK's data centers, gives a dealership customer relationship management (CRM) software, financing, inventory, and more back-office tools.

That all-in-one nature explains why people trying to buy cars, and especially those trying to sell them, have had a rough couple of days. CDK's services have been down, due to what the firm describes as a "cyber incident." CDK shut down most of its systems Wednesday, June 19, then told dealerships that evening that it restored some services. CDK told dealers today, June 20, that it had "experienced an additional cyber incident late in the evening on June 19," and shut down systems again.

"At this time, we do not have an estimated time frame for resolution and therefore our dealers' systems will not be available at a minimum on Thursday, June 20th," CDK's told customers.

A 911 vendor's malfunctioning firewall caused a statewide outage in the emergency calling system in Massachusetts on Tuesday afternoon, the state government said. A Massachusetts government press release issued yesterday said the state's 911 vendor, Comtech, "has advised State 911 that they have applied a technical solution to ensure that this does not happen again."

"A preliminary investigation conducted by the State 911 Department and Comtech determined that the outage was the result of a firewall, a safety feature that provides protection against cyberattacks and hacking," the announcement said. "The firewall prevented calls from getting to the 911 dispatch centers, also known as Public Safety Answer Points (PSAPs)."

Comtech's initial review "confirmed that the interruption was not the result of a cyberattack or hack," but "the exact reason the firewall stopped calls from reaching dispatch centers remains under review," the state said. A full review is continuing.
