Digital transformation has been positioned as a cure-all to many of the challenges today’s enterprises face. But to fully reap the benefits of a digital transformation, businesses need to do more than just adopt the latest tools and apps. They also have to change their attitudes, practices and processes around data and technology, throughout their own organization and in their interactions with partners and customers.

“Digital transformation requires a jump on the technology side, but it requires a leap on the people side,” says Bill Gundrey, executive director for digital engineering and operations at Raytheon Missiles & Defense. “At Raytheon, digital transformation is a team sport. It impacts every function in our company, as well as customers and suppliers. We had to change the way people think about data and technology.”

It took two electric trucks to cover a distance of 250 miles.

Remy Oktay, a US engineering student, has successfully completed a test run and is preparing to launch the world’s first electric flight that an electric vehicle will power.

Therefore the EV plane will need to be recharged three times.

Remy Oktay.

Oktay will perform a flyover of the electric plane, a Pipistrel Alpha Electro, at the Lafayette-Lehigh football game, where he also studies, on November 19. To do this, the electric aircraft needs to go from Hartford, Connecticut, to Easton, Pennsylvania. But there is no charging infrastructure at any of the airports in the 150 miles (240 km) as the crow flies the distance between them.

Other proteins work as well meaning the process can be scaled without interfering with food supplies.

Researchers at Princeton Engineering have found that egg whites can be used to cheaply remove salt and microplastics from seawater, according to a press release by the institution published on Thursday.

The scientists used the food substance to create an aerogel, a lightweight and porous material that can be used in many types of applications, including water filtration, energy storage, and sound and thermal insulation.

Princeton scientists discovered that egg whites can create a filtration process that requires only gravity to operate and wastes no water. They are now looking for other uses for the substance.

Solar cells that are stretchable, flexible and wearable won the day and the best poster award from a pool of 215 at Research Expo 2016 April 14 at the University of California San Diego. The winning nanoengineering researchers aim to manufacture small, flexible devices that can power watches, LEDs and wearable sensors. The ultimate goal is to design and build much bigger flexible solar cells that could be used as power sources and shelter in natural disasters and other emergencies.

Research Expo is an annual showcase of top graduate research projects for the Jacobs School of Engineering at UC San Diego. During the poster session, graduate students are judged on the quality of their work and how well they articulate the significance of their research to society. Judges from industry, who often are alumni, pick the winners for each department. A group of faculty judges picks the overall winner from the six department winners.

This year, in addition to solar cells, judges recognized efforts to develop 3D skeletal muscle on a chip; a better way to alleviate congestion in data center networks; a nano-scale all-optical sensor; fiber optic strain sensors for structural health monitoring; and a way to predict earthquake damage in freestanding structural systems.

BACKGROUND
With a rich family history in Aviation, former Oil Trader & Royal Marines Reservist, Richard Browning, founded pioneering Aeronautical Innovation company, Gravity Industries in March 2017 to launch human flight into an entirely new era.

The Gravity #JetSuit uses over 1000bhp of Jet Engine power combined with natural human balance to deliver the most intense and enthralling spectacle, often likened to the real life Ironman.

Gravity has to date been experienced by over a billion people globally and covered by virtually every media platform. The Gravity Team, based in the UK, have delivered over 100 flight & Speaking events across 30 countries including 5 TED talks.

“The team and I are delivering on the vision to build Gravity into a world class aeronautical engineering business, challenge perceived boundaries in human aviation, and inspire a generation to dare ask ‘what if…”

The fundamental laws of friction remain a mystery to this day.

Researchers at the NYU Tandon School of Engineering have discovered a fundamental friction law that is leading to the design of two-dimensional materials capable of minimizing energy loss, according to a press release from the institution published on Thursday.

Friction lies behind the invention and development of many of today’s most advanced technologies, however, its fundamental laws remain obscure to this day despite many developments in the field.

NYU Tandon School of Engineering professor of Chemical and Biomolecular Engineering Elisa Riedo and postdoctoral researcher Martin Rejhon have found evidence of a new law of friction.

Dr Charles Brenner on the longevity understanding disconnect, the best interventions for longevity, and the NR trials he’d like to see.

The Longevity Investors Conference is a key event for those interested in learning about longevity investment opportunities and finding out more about the exciting directions in which the field is accelerating. The world’s leading and most private longevity-focused investors-only conference, LIC attracts some of the most prominent thought leaders.

One of those thought leaders is Charles Brenner, the biochemist whose work on nicotinamide adenine dinucleotide (NAD), the central catalyst of metabolism, includes the discovery of nicotinamide riboside (NR) kinase pathway and the resulting tech that led to the development of NR as an NAD-booster.

As Eric Verdin did recently, Brenner is one for driving the longevity debate, even if it causes more than a few ripples, and in cautioning against overstating progress, he is a significant calibration point for our industry (Twitter wars, notwithstanding). We were able to grab a few moments with Brenner at LIC to find out more about his thoughts on the current state of play.

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers.

Now, researchers at MIT have come up with a way to improve the energy density of these nonrechargeable, or “primary,” batteries. They say it could enable up to a 50% increase in useful lifetime, or a corresponding decrease in size and weight for a given amount of power or energy capacity, while also improving safety, with little or no increase in cost.

The new findings, which involve substituting the conventionally inactive battery electrolyte with a material that is active for energy delivery, are reported today in the journal Proceedings of the National Academy of Sciences, in a paper by MIT Kavanaugh Postdoctoral Fellow Haining Gao, graduate student Alejandro Sevilla, associate professor of mechanical engineering Betar Gallant, and four others at MIT and Caltech.

It could decrease reliance on palm oil to produce biofuel.

Have you ever guessed that a leftover coffee could turn into biodiesel? Here’s a remarkable development for bioscience. Seemingly, Aston University scientists produced high-quality biodiesel microalgae fed on leftover coffee. According to Aston University’s release, this development is also a breakthrough in the microalgal cultivation system.

Dr. Vesna Najdanovic, senior lecturer in chemical engineering, and Dr. Jiawei Wang were part of a team that produced algae and subsequently turned it into fuel.

The results of the study were published in the November 2022 issue of Renewable and Sustainable Energy Reviews.

Is solar geoengineering an alternative solution to the climate crisis?

Solar geoengineering is a branch of geoengineering that focuses on reflecting sunlight back into outer space to reduce global warming. There are several solar geoengineering techniques being researched; the most feasible one consists of spraying reflective aerosols in the stratosphere.

Scientists also consider brightening marine clouds to make them more reflective.

Recently, the White House’s Office of Science and Technology Policy launched a five-year research plan to investigate methods for reflecting solar radiation back to outer space in an attempt to reduce the effects of global warming.
