Shell authorizes Vito deepwater project

Royal Dutch Shell said Tuesday it’s authorizing the multibillion-dollar Vito project in the deepwater Gulf of Mexico – the first major Gulf project announced this year. Although the offshore energy sector continues to languish after the recent oil bust, Big Oil players like Shell are now beginning to move forward with big new projects at dramatically reduced prices. While Shell isn’t revealing the project cost, Shell said it has cut the Vito cost estimate by 70 percent from the initial…

Sales picking up for oilfield service groups

Schlumberger, Halliburton, and BHGE have reported a combined 15% growth in revenues for 1Q 2018 compared to the same period last year, according to analyst Rystad Energy. Their oilfield service sales increased by 21% on average, although their oilfield equipment sales were only 1% higher. Audun Martinsen, vice president of Oilfield Service Research at Rystad, said: “With the great surge of activity in short cycle businesses – like US shale and the slower-to-respond equipment market, typically in offshore – this…

Drug fights graft-versus-host-disease in mice — ScienceDaily

An investigational drug in clinical trials for rheumatoid arthritis prevents a common, life-threatening side effect of stem cell transplants, new research from Washington University School of Medicine in St. Louis shows. Studying mice, the researchers found the drug prevented what’s known as graft-versus-host disease, a debilitating, sometimes lethal condition that develops when transplanted stem cells attack the body’s own organs or tissues. About half of patients receiving donor stem cells develop graft-versus-host disease, which can linger for months or years…

BGP leaks and cryptocurrencies

Over the few last hours, a dozen news stories have broken about how an attacker attempted (and perhaps managed) to steal cryptocurrencies using a BGP leak.

Doctors may soon be able to see a brain tumor burned away in real time

Some 80,000 Americans will be diagnosed with a brain tumor this year according to the American Brain Tumor Association. Many of them will need major surgery and chemotherapy. Sixteen thousand of them will lose the battle. But a team of USC Viterbi School of Engineering researchers are now making it easier, faster and safer for doctors to use an emerging procedure – one that involves burning away tumors in more patients, including those with brain tumors. Radiofrequency ablation, or RFA,…

3-D printed food could change how we eat

A: Food materials are pulverized under ultra-low temperature close to -100 degrees Celsius. B: Micro-sized food materials are reconstructed into a porous film-shaped material by jetting bonding an agent under optimized water content and heat conditions. The process to build film-type materials is repeated layer by layer to form to a three-dimensional food block.C: The exterior of foods and internal microstructure of a food block with specific porosity is designed to give texture with controlled human body absorption while eating…

Electrode shape improves neurostimulation for small targets

This small chip holds a 2-D electrode with a shape that can better stimulate small targets in the body over time. Credit: Purdue University image/Kayla Wiles A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Scientific Reports. The shape, called “fractal,” would be particularly useful for stimulating smaller areas, such as deep brain structures or the retina,…

CSS at Scale: LinkedIn’s New Open Source Projects Take on Stylesheet Performance

Example source and output of CSS Blocks. Text content here.  Development of CSS Blocks and OptiCSS Following the realization that selector performance and file size were hurting our site speed, we needed to make progress quickly to alleviate the issue. The team worked hard to establish new best practices, including converting our application to use BEM-style selectors and to prefer shared class names in our templates over mixins in our stylesheets. The choice to adopt BEM was controversial; many developers…

Saipem wins $190m contracts

Saipem has secured new contracts worth approximately $190m in Offshore Drilling and Offshore Engineering and Construction (E&C). In Offshore Drilling, the contract involves the sixth-generation semi-submersible rig Scarabeo 8, which is suitable for harsh and adverse environments. To be carried out offshore Norway, the drilling activities for the project will continue for approximately ten months, excluding options. Awarded by Norske Shell, the first contract refers to the development of an optional well in relation to the contract previously assigned and…

Shell to sell Argentina unit for $950M

Royal Dutch Shell said Tuesday that it has agreed to sell its downstream business in Argentina to Raizen, Shell’s joint-venture company with Cosan Ltd. for $950 million. The oil-and-gas company said that the sale includes its refinery in Buenos Aires, about 645 retail stations, its supply and distribution activities across the country and other businesses.     Once the transaction is complete, the operations acquired by Raizen will continue their relationships with Shell through commercial agreements that are worth about…
