What can salad dressing tell us about cancer? Think oil and vinegar — ScienceDaily

Researchers led by St. Jude Children’s Research Hospital scientists have identified another way the process that causes oil to form droplets in water may contribute to solid tumors, such as prostate and breast cancer. The findings appear today in the journal Molecular Cell. Researchers found evidence that mutations in the tumor suppressor gene SPOP contribute to cancer by disrupting a process called liquid-liquid phase separation. Liquid-liquid phase separation is seen often in nature and is the reason why oil and…

Analysis reveals disease’s complexity, suggests potential clinical subtypes defined by genetics and physiology — ScienceDaily

Most patients diagnosed with type 2 diabetes are treated with a “one-size-fits-all” protocol that is not tailored to each person’s physiology and may leave many cases inadequately managed. A new study by scientists at the Broad Institute of MIT and Harvard and Massachusetts General Hospital (MGH) indicates that inherited genetic changes may underlie the variability observed among patients in the clinic, with several pathophysiological processes potentially leading to high blood sugar and its resulting consequences. By analyzing genomic data with…

Securing Time with Digital Signatures

When you visit a secure website, it offers you a TLS certificate that asserts its identity. Every certificate has an expiration date, and when it’s passed due, it is no longer valid. The idea is almost as old as the web itself: limiting the lifetime of certificates is meant to reduce the risk in case a TLS server’s secret key is compromised. Certificates aren’t the only cryptographic artifacts that expire. When you visit a site protected by Cloudflare, we also…

Our Adventures in Scaling – Engineering Blog

Unpredictable Scaling Wealthfront’s position as a financial services company presents interesting scalability challenges. The announcement of a stock market decline for instance can cause a large number of our clients to simultaneously pick up their phones, load their Wealthfront accounts, and look to see how the market activity has impacted their finances. After one particularly steep market decline on February 5th of this year, Wealthfront’s site (along with those of Vanguard, TD Ameritrade, Betterment, and T. Rowe Price) had trouble…

Introducing the Cloudflare Onion Service

When: a cold San Francisco summer afternoon Where: Room 305, Cloudflare Who: 2 from Cloudflare + 9 from the Tor Project What could go wrong? Bit of Background Two years ago this week Cloudflare introduced Opportunistic Encryption, a feature that provided additional security and performance benefits to websites that had not yet moved to HTTPS. Indeed, back in the old days some websites only used HTTP — weird, right? “Opportunistic” here meant that the server advertised support for HTTP/2 via…

RJI announces theme, info session for 2019 Student Competition

Zechang Fu, Rachel Thomas, William Fries, Meiying Wu and Alex Johar won the 2018 RJI Student Competition with VeriPixel, which uses blockchain technology to allow news organizations and news consumers to verify the authenticity of photographs sent over open networks. As the internet of things technology marches forward, college students who participate in this year’s RJI Student Competition will be challenged to develop products to help improve lives in smart homes through news delivery. The research firm Gartner projects there…

The required cryptographic upgrade to BGP routing

We have talked about the BGP Internet routing protocol before. We have talked about how we build a more resilient network and how we can see outages at a country-level via BGP. We have even talked about the network community that is vital to the operation of the global Internet. Today we need to talk about why existing operational practices for BGP routing and filtering have to significantly improve in order to finally stop route leaks and hijacks; which are…

Mathematicians propose to improve cellular network coverage by using UAVs

UAVs providing network coverage. Credit: Allen Dressen RUDN University mathematicians have simulated the work of a cellular network and modeled the use of unmanned aerial vehicles as additional transmitters. Most of the available communication systems have flat coverage and do not take into account the difference in altitude, which results in the appearance of the so-called “blind” zones. Flying drones could solve this issue. The work is published in the journal IEEE Transactions on Vehicular Technology. “Drones have become a…

Welcome to Crypto Week

The Internet is an amazing invention. We marvel at how it connects people, connects ideas, and makes the world smaller. But the Internet isn’t perfect. It was put together piecemeal through publicly funded research, private investment, and organic growth that has left us with an imperfect tapestry. It’s also evolving. People are constantly developing creative applications and finding new uses for existing Internet technology. Issues like privacy and security that were afterthoughts in the early days of the Internet are…

Listen to Cloudflare’s Kenton Varda speak about originless code

JAMstack Radio is a show all about the JAMstack, a new way to build fast & secure apps or websites. In the most recent episode, the host, Brian Douglas, met with Kenton Varda, tech lead for Cloudflare Workers and author of Sandstorm.io to discuss some of the infinite uses for running code at the edge. Listen to what Kenton had to say about serverless technology in this twenty two minute podcast here: Here’s the transcript of the podcast as well:…
