[PERSPECTIVES] New Paradigms in the Clinical Management of Li-Fraumeni Syndrome

Approximately 8.5%–16.2% of childhood cancers are associated with a pathogenic/likely pathogenic germline variant—a prevalence that is likely to rise with improvements in phenotype recognition, sequencing, and variant validation. One highly informative, classical hereditary cancer predisposition syndrome is Li–Fraumeni syndrome (LFS), associated with germline variants in the TP53 tumor suppressor gene, and a >90% cumulative lifetime cancer risk. In seeking to improve outcomes for young LFS patients, we must improve the specificity and sensitivity of existing cancer surveillance programs and explore how to complement early detection strategies with pharmacology-based risk-reduction interventions. Here, we describe novel precision screening technologies and clinical strategies for cancer risk reduction. In particular, we summarize the biomarkers for early diagnosis and risk stratification of LFS patients from birth, noninvasive and machine learning–based cancer screening, and drugs that have shown the potential to be repurposed for cancer prevention.

Column: Why reporting from South Sudan is so difficult — and critically needed

In August, fellow reporter Jason Patinkin and I crossed on foot from northern Uganda into rebel-held South Sudan. Over the course of four days, we walked more than 40 miles through the bush, escorted by rebel soldiers, to shed light on one of the world’s most underreported conflicts.

Reporting on South Sudan’s war, which began in 2013, has always been a challenge due to the risk and logistical hurdles associated with accessing remote areas where fighting takes place. But over the past year, covering the war and its humanitarian fallout has become particularly difficult. Since the beginning of this year, South Sudan’s government has banned at least 20 foreign journalists in an apparent effort to silence reporters who had a track record of critically reporting on the government.

The war has had a devastating impact on South Sudanese communities, but much of it has remained out of the limelight of international media.

This systematic crackdown on the foreign press (South Sudanese journalists have long risked imprisonment and death for doing their work) coincided with two important developments. In November 2016, the United Nations warned that the violence being committed against civilians in the southern region of Equatoria risked spiraling into genocide. Then, in February, the UN declared a man-made famine, warning that 100,000 people were at risk of starving to death as a result of civil war.

Journalists seeking to cover these events were left with two equally unsavory options: self-censorship or a risky trip to rebel-held parts of the country. Only a handful of journalists have attempted the latter since fighting escalated in July last year. For us, this was our second embed with the rebels this year.

We set off from a town in northern Uganda at five in the morning, bouncing along a bumpy dirt track towards the South Sudan border. Crammed into our four-wheel drive were rebel commander Martin Abucha, a dual American and South Sudanese citizen who we planned to profile for our PBS NewsHour Weekend segment, a couple of guides, and several duffle bags stuffed with our tents, sleeping bags, emergency medical kits and provisions to last us four days.

Just as the sun began to rise above a distant range of hills that we aimed to cross later that day, our car came to a halt in front of a stream. Because of the rainy reason, it carried more water than usual. It was time to disembark and start walking, or “footing,” as South Sudanese tend to call it.

We took off our shoes and waded through the stream’s chilly waters. This was the first of a many rivers we’d have to cross along the way, either on foot or in small flimsy canoes dug out from tree trunks. Each time, we dreaded the idea of falling in with our camera gear.

The first part of our journey in northern Uganda felt very much like a hike through a national park. Passing beautiful landscapes and idyllic farming villages, one could almost forget we were headed into a war zone — but we were about to get a reality check.

We had just crossed into South Sudan when out of nowhere, two dozen armed men popped out of the tall grass and surrounded us at gunpoint.

“Stop! Who are you and where are you going?” a soldier called out in Juba Arabic from his hideout no more than 20 yards away, pointing his AK47 at us. Another one next to him had a rocket-propelled grenade propped on his shoulder, also unequivocally aiming it in our direction.

Instinctively, we threw our hands in the air and exchanged a baffled glance. Had we accidentally bumped into government soldiers? Or perhaps we had come onto the “wrong” rebels? Abucha’s group, called the Sudan People’s Liberation Army In Opposition, is the biggest but not the only armed group in Equatoria, an area rife with rival militia and bandits who exploit the security vacuum left by war.

To our relief, and only after Abucha answered a series of questions, this routine security check quickly gave way to a warm welcome. The platoon would be our escort for the next four days as we trekked to their base and to Loa, Abucha’s hometown.

Keeping up with the rebels was no easy task. Given the country’s pervasive lack of basic infrastructure, South Sudanese grow up walking for dozens of miles just to go about their daily lives. For sedentary Westerners, keeping the target pace of “two meters per second” (around five miles an hour) proved challenging amid 90-degree temperatures, all while filming and plowing our way through dense, itchy elephant grass.

The upside of the cumbersome terrain was that it kept us safe. During our four-day trip, we didn’t cross a single road, instead walking along a dizzying network of narrow bush paths the rebels seemed to know like the backs of their hands. An unwanted encounter with government troops, who tended to stick to roads and move around in vehicles as opposed to on foot, was highly unlikely.

The closest we got to government-controlled area was a visit to Loa, located just two kilometers away from a main road frequently patrolled by government soldiers. We couldn’t stay long, but the hour we spent on the ground offered us a glimpse into what villages must look like in many parts of Equatoria: burned mud huts, looted schools and clinics, fallow fields and – most strikingly – no civilians.

The war has had a devastating impact on South Sudanese communities like the one in Loa, but much of it has remained out of the limelight of international media. Our four-day venture into rebel-held South Sudan offered us a rare opportunity to report ground truths, and we are thankful for that.

U.S.-backed Syrian forces recapture Raqqa from Islamic State group

Fighters of Syrian Democratic Forces celebrate after Raqqa in Syria was liberated from Islamic State militants on Oct. 17. Photo by Erik De Castro/Reuters

U.S.-backed Syrian Democratic Forces announced Tuesday that they had captured the city of Raqqa from Islamic State militants.

“Everything is finished in Raqqa, our forces have taken full control of Raqqa,” SDF spokesman Talal Sello told AFP. A formal declaration would be announced after operations to clear any remaining sleeper cells and to remove landmines in the city were completed, Sello added.

The move is a major setback for the Islamic State which considered Raqqa the de-facto capital of its self-declared caliphate. It comes on the third anniversary of the global effort to defeat ISIS.

Raqqa was the first provincial capital to fall from government control in March 2013 after it was captured by a rebel army. The army included both Syrian opposition groups and more hard line  parties including al-Nusra and the Islamic State.

A civilian government  that was established in the city divided two months later, and less than a year later ISIS recaptured Raqqa and named the the capital of their caliphate.

About 900 civilians have been killed since the the start of the five-month operation, including 570 people in coalition air raids, according to the Syrian Network for Human Rights. The Britain-based Syrian Observatory for Human Rights put the civilian death toll at 1,130 people. American journalist James Foley was beheaded in the mountains south of the city.

SDF fighters pulled down the Islamic State’s black flag from the city’s National Hospital near the city’s stadium, according to a Reuters report.

Special presidential envoy for the Global Coalition to Defeat ISIS Brett McGurk said in August that the U.S. would attempt to perform a “stabilization” in Raqqa — including demining, removing rubble from major pathways to allow trucks and equipment through, and “basic electricity, sewage, water, the basic essentials to allow populations to come back to their home.”

It is not clear when the 300,000 civilians who have fled Raqqa since April during the operation will be able to return.

As Rohingya refugees continue to flee from persecution, here’s how you can help

More than 500,000 Rohingya Muslims have fled their homes since August to escape systematic violence at the hands of government soldiers in Myanmar. The U.N. has called the actions taken by Myanmar forces against the group “a textbook example of ethnic cleansing.”

A report released by Amnesty International on Wednesday documents widespread rape, killings and burnings of Rohingya across the Rakhine State in Myanmar. The report includes extensive interviews of Rohingya refugees who tell stories of live burnings, sexual violence and mass shootings at the hands of soldiers.

To escape persecution, Rohingya refugees are fleeing in droves to neighboring Bangladesh, a country described by some as a reluctant host for the thousands of refugees behind its borders. Conditions within Bangladesh show refugee camps beyond capacity, as organizations struggle to keep up with humanitarian aid.

Find out more: Rohingya Muslims have been denied citizenship in Myanmar since 1982, though they’ve lived in the area since the 12th century. They are not considered one of the country’s official ethnic groups. As such, their lack of official identity bars them from government services and travel.

Officials from Myanmar, a majority Buddhist state, claim Rohingya are actually immigrants from Bangladesh to justify their exclusion of the group. This most recent burst of violence comes from Myanmar’s crackdown following clashes with the Arakan Rohingya Salvation Army (ARSA). After the government declared ARSA a terrorist organization, the retaliation escalated into hundreds of Rohingya villages.

Where to give: BRAC, a top-ranked NGO based out of Bangladesh, is scaling up humanitarian efforts for clean water, health, sanitation and child care for refugees from Myanmar. You can learn more about their efforts here.

An emergency appeal was made by the Disasters Emergency Committee for immediate crisis relief funds. DEC distributes funds to 13 member aid organizations.
UNHCR, UNICEF and Save the Children have donation pages dedicated to the crisis, as does the International Rescue Committee. CNN’s Public Good page provides a user-friendly resource to find NGOs that match your giving goals.

To give to starvation relief, try Action Against Hunger or the World Food Programme.

Be sure to research organizations receiving your financial contributions, not only to find the best organization aligned with your goals, but also to avoid potential scams.

Sony Discusses What Lessons Can be Learned from the Failure of Concord

Sony president Hiroki Totoki in a Q&A session with investors was asked about the failure of Concord, which was shut down less than two weeks after it released.

"Currently, we are still in the process of learning," said Totoki (via VideoGamesChronicle). "And basically, with regards to new IP, of course, you don’t know the result until you actually try it.

"So for us, for our reflection, we probably need to have a lot of gates, including user testing or internal evaluation, and the timing of such gates. And then we need to bring them forward, and we should have done those gates much earlier than we did.

"Also, we have a siloed organisation, so going beyond the boundaries of those organisations in terms of development, and also sales, I think that could have been much smoother.

"And then going forward, in our own titles and in third-party titles, we do have many different windows. And we want to be able to select the right and optimal window so that we can deploy them on our own platform without cannibalization, so that we can maximize our performance in terms of title launches. That’s all I have."

Sony senior vice president for finance and IR Sadahiko Hayakawa discussed the success of Helldivers 2 and the failure of Concord.

"We launched two live-service games this year," he said. "Helldivers 2 was a huge hit, while Concord ended up being shut down. We gained a lot of experience and learned a lot from both.

"We intend to share the lessons learned from our successes and failures across our studios, including in the areas of title development management as well as the process of continually adding expanded content and scaling the service after its release so as to strengthen our development management system.

"We intend to build on an optimum title portfolio during the current mid-range plan period that combines single-player games – which are our strengths and which have a higher predictability of becoming hits due to our proven IP – with live-service games that pursue upside while taking on a certain amount of risk upon release."

Concord released for the PlayStation 5 and PC on August 23, and it was shut down on September 6.

Grand Theft Auto: The Definitive Edition trilogy on PC gets a classic lighting update from the mobile version

My strongest and most enduring memory of Grand Theft Auto will always be creasing into complete hysterics watching my mate pile into a crumpled police officer with a wooden baseball bat in GTA 3 after school one time. Young’uns these days just don’t appreciate how revolutionary it was to be able to hit a cop with a thing after he’d already fallen over. Suffice it to say I’ve got good memories of the open world series’ nascent forays into 3D, though never enough to tempt me into revisiting them, especially given the poor reception to Grand Theft Auto: The Trilogy - The Definitive Edition. I can sympathise. I’m annoyed just having to type a semicolon and a dash in the same game name.

How a Robot Is Grabbing Fuel From a Fukushima Reactor



Thirteen years since a massive earthquake and tsunami struck the Fukushima Dai-ichi nuclear power plant in northern Japan, causing a loss of power, meltdowns and a major release of radioactive material, operator Tokyo Electric Power Co. (TEPCO) finally seems to be close to extracting the first bit of melted fuel from the complex—thanks to a special telescopic robotic device.

Despite Japan’s prowess in industrial robotics, TEPCO had no robots to deploy in the immediate aftermath of the disaster. Since then, however, robots have been used to measure radiation levels, clear building debris, and survey the exterior and interior of the plant overlooking the Pacific Ocean.

It will take decades to decommission Fukushima Dai-ichi, and one of the most dangerous, complex tasks is the removal and storage of about 880 tons of highly radioactive molten fuel in three reactor buildings that were operating when the tsunami hit. TEPCO believes mixtures of uranium, zirconium and other metals accumulated around the bottom of the primary containment vessels (PCVs) of the reactors—but the exact composition of the material is unknown. The material is “fuel debris,” which TEPCO defines as overheated fuel that has melted with fuel rods and in-vessel structures, then cooled and re-solidified. The extraction was supposed to begin in 2021 but ran into development delays and obstacles in the extraction route; the coronavirus pandemic also slowed work.

While TEPCO wants a molten fuel sample to analyze for exact composition, getting just a teaspoon of the stuff has proven so tricky that the job is years behind schedule. That may change soon as crews have deployed the telescoping device to target the 237 tons of fuel debris in Unit 2, which suffered less damage than the other reactor buildings and no hydrogen explosion, making it an easier and safer test bed.

“We plan to retrieve a small amount of fuel debris from Unit 2, analyze it to evaluate its properties and the process of its formation, and then move on to large-scale retrieval,” says Tatsuya Matoba, a spokesperson for TEPCO. “We believe that extracting as much information as possible from the retrieved fuel debris will likely contribute greatly to future decommissioning work.”

How TEPCO Plans to Retrieve a Fuel Sample

Getting to the fuel is easier said than done. Shaped like an inverted light bulb, the damaged PCV is a 33-meter-tall steel structure that houses the reactor pressure vessel where nuclear fission took place. A 2-meter-long isolation valve designed to block the release of radioactive material sits at the bottom of the PCV, and that’s where the robot will go in. The fuel debris itself is partly underwater.

The robot arm is being preceded by a smaller telescopic device. The telescopic device, which is trying to retrieve 3 grams of the fuel debris without further contamination to the outside environment, is similar to the larger robot arm, which is better suited for the retrieval of larger bits of debris.

Mitsubishi Heavy Industries, the International Research Institute for Nuclear Decommissioning and UK-based Veolia Nuclear Solutions developed the robot arm to enter small openings in the PCV, where it can survey the interior and grab the fuel. Mostly made of stainless steel and aluminum, the arm measures 22 meters long, weighs 4.6 tons and can move along 18 degrees of freedom. It’s a boom-style arm, not unlike the robotic arms on the International Space Station, that rests in a sealed enclosure box when not extended.

The arm consists of four main elements: a carriage that pushes the assembly through the openings, arm links that can fold up like a ream of dot matrix printer paper, an arm that has three telescopic stages, and a “wand” (an extendable pipe-shaped component) with cameras and a gripper on its tip. Both the arm and the wand can tilt downward toward the target area.

After the assembly is pushed through the PCV’s isolation valve, it angles downward over a 7.2-meter-long rail heading toward the base of the reactor. It continues through existing openings in the pedestal, a concrete structure supporting the reactor, and the platform, which is a flat surface under the reactor.

Then, the tip is lowered on a cable like the grabber in a claw machine toward the debris field at the bottom of the pedestal. The gripper tool at the end of the component has two delicate pincers (only 5 square millimeters), that can pinch a small pebble of debris. The debris is transferred to a container and, if all goes well, is brought back up through the openings and placed in a glovebox: A sealed, negative-pressure container in the reactor building where initial testing can be performed. It will then be moved to a Japan Atomic Energy Agency facility in nearby Ibaraki Prefecture for detailed analysis.

While the gripper on the telescopic device currently being used was able to reach the debris field and grasp a piece of rubble—it’s unknown if it was actually melted fuel—last month, two of the four cameras on the device stopped working a few days later, and the device was eventually reeled back into the enclosure box. Crews confirmed there were no problems with signal wiring from the control panel in the reactor building, and proceeded to perform oscilloscope testing. TEPCO speculates that radiation passing through camera semiconductor elements caused electrical charge to build up, and that the charge will drain if the cameras are left on in a relatively low-dose environment. It was the latest setback in a very long project.

“Retrieving fuel debris from Fukushima Daiichi Nuclear Power Station is an extremely difficult task, and a very important part of decommissioning,” says Matoba. “With the goal of completing the decommissioning in 30 to 40 years, we believe it is important to proceed strategically and systematically with each step of the work at hand.”

This story was updated on 15 October, 2024 to clarify that TEPCO is using two separate tools (a smaller telescopic device and a larger robot arm) in the process of retrieving fuel debris samples.
