A star known by the unassuming name of KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year. In 2015 a team of astronomers announced that the star underwent a series of very brief, non-periodic dimming events while it was being monitored by…
WikiLeaks’ Assange Promises Leaks on U.S. Election, Google
WikiLeaks founder Julian Assange promised “significant” disclosures on subjects including the U.S. election and Google in the coming weeks as the secret-spilling group marked its 10th anniversary on Tuesday. Assange said WikiLeaks plans to start publishing new material starting this week, but wouldn’t specify the timing and subject. Speaking by video link to an anniversary…
Scientists Trigger Controlled Rogue Wave in the Lab
Scientists have created what just a few years ago many thought was unpredictable, and thus uncontrollable — a rogue wave. Researchers at the Aalto University can now create and control rogue waves under laboratory conditions realistic to ocean environments. “This will help us not only to predict oceanic extreme events, but also in the design…
Photo of the Day: Final Descent Image from Rosetta Spacecraft
A new image of comet 67P/Churyumov-Gerasimenko was taken by the European Space Agency’s (ESA) Rosetta spacecraft shortly before its controlled impact into the comet’s surface on Sept. 30, 2016. Confirmation of the end of the mission arrived at ESA’s European Space Operations Center in Darmstadt, Germany, at 4:19 a.m. PDT (7:19 a.m. EDT / 1:19…
3D-Printed Fish Fossil Offers Clues to the Origins of Human Teeth
Scientists believe a 400 million-year-old fish fossil holds clues to the evolutionary origins of human teeth. Upon excavation, it wasn’t clear whether the ancient armored fish had jaws or teeth. But CT scans allowed scientists to create a 3D-printed model of the fossil, revealing both a jaw and teeth. How and when teeth first appeared…
Tuesdays with Roger: Moving Forward with LTE-U
Roger takes a dive into LTE-U now that the LTE-U coexistence test plan has been released.
TorqueTrak TPM2 provides continuous shaft torque & mechanical-power data
Easy installation – Rotating collar and stationary ring are split and bolt together around the shaft, so no machine assembly or shaft modification is required.
Prodways research claims a 5X faster 3D printing technology
The Prodways R&D teams have been collaborating with CEA-LITEN for two years. This collaboration with this institute of CEA – CEA Tech – is working on a new metal 3D printing process using metal powder combined with organic binders. Recently, the team revealed its first successful production of titanium parts using this new exclusive process. […]
Can you get injection molded quality parts without post processing from 3D printers?
Two features of 3D printers that can be issues for users are the surface finish quality of the part and the subsequent post processing often needed to finish the part. The developers at Rize created a 3D printer to address these issues. The Rize One 3D printer is small enough to sit on a desktop, […]
Clippard unveils precision diaphragm regulators
When Clippard invented miniature regulators in 1962, the MAR Series became very popular as a simple, robust, and cost-effective regulator in a small package with exceptionally long life. As regulator…
NASA’s Curiosity Rover Begins Next Mars Chapter
After collecting drilled rock powder in arguably the most scenic landscape yet visited by a Mars rover, NASA’s Curiosity mobile laboratory is driving toward uphill destinations as part of its two-year mission extension that commenced Oct. 1. The destinations include a ridge capped with material rich in the iron-oxide mineral hematite, about a mile-and-a-half (two-and-a-half…
Navy Celebrates National Cybersecurity Awareness Month
October marks the annual cybersecurity education and awareness campaign. As Navy systems and functions become increasingly reliant on cyberspace, adhering to best cyber practices and behaving with integrity online are critical to protecting Navy networks. The cyber threat is real. Between September 2014 and June 2015, there were 30-million known malicious intrusion attempts on Department…
Silicon Fluorescent Material Developed Enabling Observations Under a Bright ‘Biological Optical Window’
Researchers in Japan developed a silicon fluorescent material that is very low in toxicity and high in luminescence efficiency, compared to conventional materials. Under near-infrared radiation (NIR) at wavelengths of 650 to 1,000 nm — the range known as the “biological optical window” — that is capable of passing through living systems, the joint group…
Metric rigid couplings with step bores
Ruland has expanded its line of rigid couplings to include metric sizes with step bores. This gives equipment manufacturers designing precision servo driven systems or shaft-to-shaft connections a…
Verizon Pushes FCC to Move on Additional High-Frequency Bands for 5G
It seems 3.85 GHz was a nice starter, but isn’t nearly enough high-frequency 5G spectrum for Verizon’s liking. The carrier in a recent filing urged the FCC to swiftly move forward with its plan to open up additional high-frequency spectrum for 5G, asking the commission to focus on bands that are near the 28 GHz…
Pioneering Space Requires Living Off the Land in the Solar System
As NASA continues preparing for the Journey to Mars, the technology now in development is expanding beyond the spacecraft and propulsion systems needed to get there. NASA scientists and engineers also are developing systems to harness abundant resources available in the solar system to support these pioneering missions. The practice is called in-situ resource utilization, or ISRU.…
Photo of the Day: Space Station’s Expandable Habitat
The Bigelow Expandable Activity Module (BEAM) is seen attached to the Tranquility module of the International Space Station. BEAM is an is anexperimental expandable habitat. Expandable habitats, occasionally described as inflatable habitats, greatly decrease the amount of transport volume for future space missions. These “expandables” weigh less and take up less room on a rocket while allowing…
Gone Phishin’: It’s Tough to Detect Harmful Emails
You might not fall for that faux Nigerian prince who urgently needs you to fork over $5,000 so you can rake in a cool million, but you might fall for well-disguised phishing scams, according to a study from Carnegie Mellon University. The study, conducted by Carnegie Mellon’s CyLab Security and Privacy Institute, showed a set…
Official: No ‘Manipulation’ of Data Seen in Election Hacks
Hackers have made their way into state election systems “in a few cases,” but the federal government hasn’t found “any manipulation” so far of voting information, the Homeland Security secretary said Saturday. Twenty-one states have contacted the agency for help in safeguarding their election systems, and Jeh Johnson is urging additional requests for cybersecurity assistance.…
Federal Judge Rejects Suit Over U.S. Control of Internet Group
