5G rollout meets major pushback

The Grind

The highly-anticipated rollout of fifth generation cellular technology (5G) is running into some trouble.

First of all, the project is expected to take 10 years and will require an estimated 500,000 new cell towers and small-cell sites.

A handful of cities in California have already issued ordinances to block cell sites in residential areas based on concerns about 5G’s effects on health and property value.

The Details

A lawsuit filed by more than 90 cities and counties accuses the FCC of overstepping its authority by building infrastructure without input from local officials.

“Most cities want 5G, but they don’t want to be told how, when, and at what cost,” reports the Wall Street Journal. “Rules the FCC has already passed, meant to expedite 5G’s rollout, might well be creating acrimony that serves to do the exact opposite.”

The FCC’s “5G Fast” plan gives jurisdictions 90 days to approve new 5G antennas and limits what governments can charge carriers for the real estate on which the new infrastructure is built.

“What the wireless guys are asking is for cities to treat them totally differently than every other entity asking for construction permits,” says Blair Levin, a former FCC executive. “I think it will backfire because…instead of a cooperative relationship you’ll get a hostile relationship.”

President Trump views the rollout as crucial in winning the tech race with China, even though his decision to ban American ISPs from using Chinese parts has slowed the process.

“We cannot allow any other country to out-compete the United States in this powerful industry of the future,” said Trump in April. “We are leading by so much in so many different industries of that type, and we just can’t let that happen. The race to 5G is a race America must win.”

He also claimed the rollout would create 3 million American jobs and add $500 billion to the US economy.

Researchers develop a better way to monitor brain pressure

The Grind

Researchers at MIT have developed a minimally invasive way to monitor intracranial pressure (ICP) in patients suffering from traumatic brain injuries or diseases like meningitis.

The current method is so invasive – it requires drilling a hole into the skull – that it is only used in emergencies.

Normal ICP is between 5 and 15 mmHg. If that pressure increases to 20 mmHg or higher, blood flow is restricted and the patient is at risk of cell death, loss of consciousness, and death.

In severe cases, doctors relieve ICP by draining fluid from the brain or by removing a piece of the skull to allow more room for the brain to expand.

“Ultimately, the goal is to have a monitor at the bedside in which we only use minimally invasive or noninvasive measurements and produce estimates of ICP in real time,” explains senior study author Thomas Heldt, an associate professor of electrical and biomedical engineering.

The Details

Heldt began looking for a new way to monitor ICP more than 10 years ago.

In 2012, his team developed a new way to estimate a patient’s ICP based on arterial blood pressure and the velocity of blood flow entering the brain.

This year, Heldt tested that theory on real patients with injuries so severe that invasive ICP measurements were already being done.

The new method was successful to within 1 mmHg of the measurements taken using the invasive method.

The Takeaway

In theory, Heldt’s method will make it possible to monitor the brains of patients with diseases like encephalitis, malaria, and meningitis.

“In the past, for these conditions, we would never consider ICP monitoring,” says co-author Robert Tasker. “What the current research has opened up for us is the possibility that we can include these other patients and try to identify not only whether they’ve got raised ICP but some degrees of magnitude to that.”

Moving forward, Heldt will oversee two follow-up studies to test the new method on a wider range of patients and to learn more about how ICP affects the brain.

“There’s been a fundamental limitation of studying intracranial pressure and its relation to a variety of conditions,” adds Heldt. “Simply because we didn’t have an accurate and robust way to get at the measurement non-invasively.”
