After 15 years and $500m the US Navy decides it doesn’t need shipboard railguns after all • The Register

Voice Of EU

After more than 15 years of R&D, and half a billion dollars of funding, the United States Navy has decided to give up on the prospect of mounting enormous railguns on its ships. For the moment, at least.

The project was intended to produce a mighty weapon which could fire projectiles at Mach 7 at targets over 100 miles (161km) away, using electromagnets rather than chemical reactions to propel them. But fresh from deliberately creating a 3.9-magnitude earthquake 100 miles (161km) off the coast of Florida to rattle the windows on its latest aircraft carrier, the Navy has decided it can no longer spare the money for continued research.

“Given fiscal constraints, combat system integration challenges and the prospective technology maturation of other weapon concepts, the Navy decided to pause research and development of the Electromagnetic Railgun [EMRG] at the end of 2021,” it said.

Despite producing a weapon that undoubtedly worked to some extent, the programme had been plagued with technological and practical difficulties (see video below).

While formidable, the weapon never managed to reach its promised range and its prodigious power requirements meant that at the time the programme was suspended, of its current fleet only the US Navy’s three weird-looking Zumwelt-class stealthy destroyers generated enough electricity to power the EMRG.

The project had also faced declining funding and cancellation of the Gun-Launched Guided Projectile steerable ammunition which was being specially built for it. Its capabilities also unhelpfully fell somewhere between advanced ammunition for conventional weapons and those of a number of new, longer-ranged hypersonic missiles currently in development.

A report from Popular Science also noted that “developmental challenges included the stalled development of a universal common mount,” meaning that despite its lengthy and expensive gestation, the Navy had not even got so far as creating a way of fitting the weapon to a ship yet.

Ultimately, despite its promise, the US Navy has seemingly lost patience and dumped the EMRG into the “valley of death”, the gap between development and actual use that can befall promising technology which faces major practical challenges, funding problems or research issues. Or, as in this case, all three.

The cancellation of the EMRG does not mean that naval railguns are impossible, however. China has already conducted sea trials with a shipboard railgun mounted on a Type 072III-class landing ship as far back as 2018, a fact which had been spurring US railgun development along. Now it seems the US Navy, at least, is content to counter the prospect of a Chinese naval supergun with other projects and capabilities currently in development.

For those who continue to yearn for huge seaborne electromagnetically propelled projectiles – and let’s face it, who doesn’t? – there is still the prospect of the Electromagnetic Aircraft Launch System fitted to the USN’s new Gerald R Ford-class aircraft carriers. These use linear motors for cheerfully slinging both naval aircraft into the air and unsuspecting trucks into the water at high velocity. ®

It’s fair to say that in the last couple of years the British monarchy has been put under a microscope for the way they handle their own family members, whether that be an heir to the throne and his American wife, or a prince embroiled in a civil sex abuse case. In a two parter titled Royally Flush, however, the Broccoli Productions’ Human Resources podcast goes back in time to investigate the royal family’s role in the slave trade in Britain, questioning how influential they were in trying to prevent abolition.

This is clearly a pandemic production as audio quality can sometimes be shaky, but the content is an important listen. As the country gears up to celebrate the Queen’s platinum jubilee, writer and host, Moya Lothian-McLean takes us on an unexplored trip down memory lane, presenting fascinating insights into why – despite ample evidence that the monarchy was historically instrumental in propping up the slave trade in Britain – we haven’t heard so much as a sorry coming from Buckingham Palace, according to the program maker.

Talking points

  • Never underestimate the skill that goes into making a good podcast. Over a year since Meghan and Harry’s audio production company Archewell signed a podcast deal with Spotify, they’ve only managed to release a single podcast. Hence, presumably the job ads Spotify posted this week, looking for full-time staff to help Archewell.

California’s net neutrality law dodges Big Telecom bullet • The Register

Voice Of EU

Published

on

The US Ninth Circuit Court of Appeals on Friday upheld a lower court’s refusal to block California’s net neutrality law (SB 822), affirming that state laws can regulate internet connectivity where federal law has gone silent.

The decision is a blow to the large internet service providers that challenged California’s regulations, which prohibit network practices that discriminate against lawful applications and online activities. SB 822, for example, forbids “zero-rating” programs that exempt favored services from customer data allotments, paid prioritization, and blocking or degrading service.

In 2017, under the leadership of then-chairman Ajit Pai, the US Federal Communications Commission tossed out America’s net neutrality rules, to the delight of the internet service providers that had to comply. Then in 2018, the FCC issued an order that redefined broadband internet services, treating them as “information services” under Title I of the Communications Act instead of more regulated “telecommunications services” under Title II of the Communications Act.

California lawmaker Scott Wiener (D) crafted SB 822 to implement the nixed 2015 Open Internet Order on a state level, in an effort to fill the vacuum left by the FCC’s abdication. SB 822, the “California Internet Consumer Protection and Net Neutrality Act of 2018,” was signed into law in September 2018 and promptly challenged.

In October 2018, a group of cable and telecom trade associations sued California to prevent SB 822 from being enforced. In February, 2021, Judge John Mendez of the United States District Court for Eastern California declined to grant the plaintiffs’ request for an injunction to block the law. 

So the trade groups took their case to the Ninth Circuit Court of Appeals, which has now rejected their arguments. While federal laws can preempt state laws, the FCC’s decision to reclassify broadband services has moved those services outside its authority and opened a gap that state regulators are now free to fill.

“We conclude the district court correctly denied the preliminary injunction,” the appellate ruling [PDF] says. “This is because only the invocation of federal regulatory authority can preempt state regulatory authority.

The FCC no longer has the authority to regulate in the same manner that it had when these services were classified as telecommunications services

“As the D.C. Circuit held in Mozilla, by classifying broadband internet services as information services, the FCC no longer has the authority to regulate in the same manner that it had when these services were classified as telecommunications services. The agency, therefore, cannot preempt state action, like SB 822, that protects net neutrality.”

The Electronic Frontier Foundation, which supported California in an amicus brief, celebrated the decision in a statement emailed to The Register.

“EFF is pleased that the Ninth Circuit has refused to bar enforcement of California’s pioneering net neutrality rules, recognizing a very simple principle: the federal government can’t simultaneously refuse to protect net neutrality and prevent anyone else from filling the gap,” a spokesperson said.

“Californians can breathe a sigh of relief that their state will be able to do its part to ensure fair access to the internet for all, at a time when we most need it.”

There’s still the possibility that the plaintiffs – ACA Connects, CTIA, NCTA and USTelecom – could appeal to the US Supreme Court.

In an emailed statement, the organizations told us, “We’re disappointed and will review our options. Once again, a piecemeal approach to this issue is untenable and Congress should codify national rules for an open Internet once and for all.” ®

RCSI scientists find potential treatment for secondary breast cancer

Voice Of EU

Published

on

An existing drug called PARP inhibitor can be used to exploit a vulnerability in the way breast cancer cells repair their DNA, preventing spread to the brain.

For a long time, there have been limited treatment options for patients with breast cancer that has spread to the brain, sometimes leaving them with just months to live. But scientists at the Royal College of Surgeons Ireland (RCSI) have found a potential treatment using existing drugs.

By tracking the development of tumours from diagnosis to their spread to the brain, a team of researchers at RCSI University of Medicine and Health Sciences and the Beaumont RCSI Cancer Centre found a previously unknown vulnerability in the way the tumours repair their DNA.

An existing kind of drug known as a PARP inhibitor, often used to treat heritable cancers, can prevent cancer cells from repairing their DNA because of this vulnerability, culminating in the cells dying and the patient being rid of the cancer.

Prof Leonie Young, principal investigator of the RCSI study, said that breast cancer research focused on expanding treatment options for patients whose disease has spread to the brain is urgently needed to save the lives of those living with the disease.

“Our study represents an important development in getting one step closer to a potential treatment for patients with this devastating complication of breast cancer,” she said of the study, which was published in the journal Nature Communications.

Deaths caused by breast cancer are often a result of treatment relapses which lead to tumours spreading to other parts of the body, a condition known as secondary or metastatic breast cancer. This kind of cancer is particularly aggressive and lethal when it spreads to the brain.

The study was funded by Breast Cancer Ireland with support from Breast Cancer Now and Science Foundation Ireland.

It was carried out as an international collaboration with the Mayo Clinic and the University of Pittsburgh in the US. Apart from Prof Young, the other RCSI researchers were Dr Nicola Cosgrove, Dr Damir Varešlija and Prof Arnold Hill.

“By uncovering these new vulnerabilities in DNA pathways in brain metastasis, our research opens up the possibility of novel treatment strategies for patients who previously had limited targeted therapy options”, said Dr Varešlija.
