Japan Achieves 402 TB/s Data Rate – Using Current Fiber Technology

Published

on


Tom’s Hardware reports that Japan’s National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) set a 402 terabits per second data transfer record — over commercially available optical fiber cables.

The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate.

As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent.

“This is achievable with currently available technology used by internet service providers…” the article points out.

“With ‘beyond 5G’ potential speeds achievable through commercially available cables, it will likely further a new generation of internet services.”

My Doctor Misdiagnosed My Diabetes — and I’m Not Alone. What You Need to Know

Published

on


For the longest time, type 1 diabetes was known as a childhood disease. Even until recently, it was still called “juvenile diabetes.” I’m here to tell you that just because you’re an adult doesn’t mean you’ve escaped the wrath of this illness.

I know this because it happened to me. At the age of 30, I was misdiagnosed with type 2 diabetes for over six months. It wasn’t until I started sharing my diagnosis on TikTok that I discovered the truth and that this could happen to someone my age.

Roughly 60% of diagnoses today occur in adults who are 20 years of age or older. This form of type 1 diabetes is called Latent Autoimmune Diabetes of Adults. On top of that, 90% of those diagnosed with type 1 have no family history. 

Rates for people living with diabetes are expected to more than double to 1.3 billion by 2050. This will impact both people with type 1 and type 2 diabetes. Spreading awareness about symptoms and early screening for type 1 diabetes will help people get the correct diagnosis and treatment they need sooner.

Research published in The Lancet projects a steady increase in the prevalence of type 2 diabetes in coming years.

There is a lack of awareness about diabetes, even within the medical community. Because of this, many people go undiagnosed or misdiagnosed with type 2 diabetes for months or even years. Here’s what you need to know.

The difference between type 1 and type 2 diabetes

Type 1 diabetes occurs when the pancreas no longer produces insulin, the hormone that regulates blood glucose, because the immune system attacks itself. Meanwhile, type 2 diabetes occurs due to insulin resistance, often due to lifestyle factors, and tends to be hereditary. As many as 11% of patients diagnosed with type 2 diabetes might actually have LADA. There are a couple things we can all do to prevent others from going undiagnosed and feeling ill for as long as I did. 

The first is to know the signs of type 1 diabetes. The tell-tale symptoms are excessive thirst and urination, extreme feeling of fatigue, blurred vision and weight loss. When I was diagnosed, I was experiencing all of these symptoms and had lost over 20 pounds. After months of misdiagnosis, I saw an endocrinologist who ordered blood tests, and within weeks, I had the correct type 1 diagnosis.

Had my glucose levels gone unchecked for longer, I could have gone into diabetic ketoacidosis or DKA, which can be deadly. Up to 30% of those diagnosed in the US are discovered at this stage. 

Another way we can prevent loss of life or sickness is with early screening for indicators of type 1 diabetes. Two blood tests are used to aid in diagnosis: A c-peptide test, which measures how much insulin a person is making themselves, and an islet autoantibody test, which screens for markers of the autoimmune process associated with type 1 diabetes. With these results, people can prepare and seek out treatment to offset the disease and/or treat it.

New legislation could help

Recent legislation aims to bring early screening for type 1 diabetes to the forefront of preventative care.  

Last month, a bipartisan bill called the Strengthening Collective Resources for Encouraging Education Needed for Type 1 Diabetes Act was introduced in the House of Representatives. The bill directs the Centers for Disease Control and Prevention to conduct a national campaign to increase awareness and knowledge of type 1 detection, screening and management, and will allocate $5 million to the CDC to carry it out.

On my end, I will continue to share my story through articles like this one, videos on social media and interviews on my podcast, Diabetech. My hope is that no one will experience the long stretch of illness I experienced before getting the correct diagnosis and treatment needed.

Diabetes is a complex and complicated disease to manage. Devices like insulin pumps, smart insulin pens and continuous glucose monitors make living with the disease easier to manage, but they come with a steep learning curve. 

I’m fortunate to be able to interview experts in the field on my podcast who help me and my audience stay informed on the latest tools and technology. I encourage anyone living with this disease to connect with me on YouTube, Instagram or TikTok to feel less alone and more in charge of your personal health.

Midjourney is creating Donald Trump pictures when asked for images of ‘the president of the United States’

Published

on


Midjourney, a popular AI-powered image generator, is creating images of Donald Trump and Joe Biden despite saying that it would block users from doing so ahead of the upcoming US presidential election.

When Engadget prompted the service to create an image of “the president of the United States,” Midjourney generated four images in various styles of former president Donald Trump.

When asked to create an image of “the next president of the United States,” the tool generated four images of Trump as well.

When Engadget prompted Midjourney to create an image of “the current president of the United States,” the service generated three images of Trump and one image of former president Barack Obama.

The only time Midjourney refused to create an image of Trump or Biden was when it was asked to do so explicitly. “The Midjourney community voted to prevent using ‘Donald Trump’ and ‘Joe Biden’ during election season,” the service said in that instance. Other users on X were able to get Midjourney to generate Trump’s images too.

The tests show that Midjourney’s guardrails to prevent users from generating images of Trump and Biden ahead of the upcoming US presidential election aren’t enough — in fact, it’s really easy for people to get around them. Other chatbots like OpenAI’s ChatGPT, Microsoft’s Copilot, Google’s Gemini and Meta AI did not create images of Trump or Biden despite multiple prompts.

Midjourney did not respond to a request for comment from Engadget.

Midjourney was one the first AI-powered image generators to explicitly ban users from generating images of Trump and Biden. “I know it’s fun to make Trump pictures — I make Trump pictures,” the company’s CEO, David Holz, told users in a chat session on Discord, earlier this year. “However, probably better to just not — better to pull out a little bit during this election. We’ll see.” A month later, Holz reportedly told users that it was time to “put some foots down on election-related stuff for a bit” and admitted that “this moderation stuff is kind of hard.” The company’s existing content rules prohibit the creation of “misleading public figures” and “events portrayals” with the “potential to mislead.”

Last year, Midjourney was used to create a fake image of Pope Benedict wearing a puffy white Balenciaga jacket that went viral. It was also used to create fake images of Trump being arrested ahead of his arraignment at the Manhattan Criminal Court last year for his involvement in a hush money payment made to adult film star Stormy Daniels. Shortly afterwards, the company halted free trials of the service and, instead, required people to pay at least $10 a month to use it.

Last month, the Center for Countering Digital Hate, a non-profit organization that aims to stop the spread of misinformation and hate speech online, found that Midjourney’s guardrails against generating misleading images of popular politicians including Trump and Biden failed 40% of its tests. The CCDH was able to use Midjourney to create an image of president Biden being arrested and Trump appearing next to a body double. The CCDH was also able to bypass Midjourney’s guardrails by using descriptions of each candidate’s physical appearance rather than their names to generate misleading images.

“Midjourney is far too easy to manipulate in practice – in some cases it’s completely evaded just by adding punctuation to slip through the net,” wrote CCDH CEO Imran Ahmed in a statement at the time. “Bad actors who want to subvert elections and sow division, confusion and chaos will have a field day, to the detriment of everyone who relies on healthy, functioning democracies.

Earlier this year, a coalition of 20 tech companies including OpenAI, Google, Meta, Amazon, Adobe and X signed an agreement to help prevent deepfakes in elections taking place in 2024 around the world by preventing their services from generating images and other media that would influence voters. Midjourney was absent from that list.
