P&G Closer to Customizing Drug Tablets Thanks to 3D Printing

April 5, 2021

A new study by P&G researchers shows how personalized medicine can leverage 3D printing

American multinational Procter and Gamble(P&G) is breaking ground in personalized medicine. Committed to delivering consumer-centric creations, researchers at the company’s Singapore Innovation Center (SgIC) have teamed up with the National University of Singapore and the A*STAR – Agency for Science, Technology, and Research, to develop 3D printed customized drug tablets with specific dosages, release durations, and multiple drug combinations. In a new study published in Elsevier’s Journal of Controlled Release, the researchers show a simple, low-cost, and efficient 3D printing method for fabricating bespoke drug pills that are safe for consumption. In the future, this technology could enable broader access to personalized medicine and better treatments for patients, specifically designed for their particular physiology and needs.

For years, there has been growing interest in personalized medicine, which could help overcome the limitations of traditional “trial-and-error” treatment and offer more effective medications for individual patients. In fact, the impressive success of targeted therapies on cancer and several chronic medical conditions is a testament to the possibilities for this emerging healthcare approach. Individualized drug therapies could even disrupt current drug manufacturing protocols for large batch productions and could eventually reduce healthcare costs by addressing the underlying causes of medical problems immediately – in a preventive way.

China has started training its military personnel with the help of virtual reality (VR) technologies to increase their combat capabilities, according to reports.

VR refers to a computer-generated simulation in which a participant can interact within an artificial three-dimensional environment with the help of electronic devices.

VR devices include specially-made goggles that have a screen-display and gloves fitted with sensors.

This enables the participant to have a realistic experience while carrying out activities under a simulated environment.

In virtual reality, the software used by developers creates a virtual or simulated environment that can be experienced by participants who wear the hardware devices like VR goggles, headphones, and gloves.

While the use of virtual reality has been quite common in video games and other recreational activities, there has been an increasing utilization of the technology in the military domain as well.

This Y Combinator startup is taking lab-grown meat upscale with elk, lamb and Wagyu beef cell lines

April 5, 2021

By Jonathan Shieber

Last week a select group of 20 employees and guests gathered at an event space on the San Francisco Bay, and, while looking out at the Bay Bridge, dined on a selection of choice elk sausages, Wagyu meatloaf and lamb burgers — all of which were grown from a petri dish.

The dinner was a coming out party for Orbillion Bio, a new startup pitching today in Y Combinator’s latest demo day, that’s looking to take lab-grown meats from the supermarket to high-end, bespoke butcher shops.

Instead of focusing on pork, chicken and beef, Orbillion is going after so-called heritage meats — the aforementioned elk, lamb and Wagyu beef to start.

By focusing on more expensive-end products, Orbillion doesn’t have as much pressure to slash costs as dramatically as other companies in the cellular meat market, the thinking goes.

But there’s more to the technology than its bougie beef, elite elk and luscious lamb meat.

“Orbillion uses a unique accelerated development process producing thousands of tiny tissue samples, constantly iterating to find the best tissue and media combinations,” according to Holly Jacobus, whose firm, Joyance Partners, is an early investor in Orbillion. “This is much less expensive and more efficient than traditional methods and will enable them to respond quickly to the impressive demand they’re already experiencing.”

TINY ROBOTS CAN NOW SMUGGLE DRUGS INTO BRAIN TUMORS

April 4, 2021

The future of cancer treatment may be robot-delivered.

By Jay Sprogell

THE FUTURE OF MEDICINE is going to be hand-delivered — but not by mail carriers. Instead, life-saving drugs will be parceled, smuggled, and transported in the body via tiny, self-propelled microbots.

In a study published Wednesday in the journal Science Robotics, a research team in China designed a new kind of bio-hybrid microbot that uses clever biological disguises to get even closer to the source of disease in the body in order to provide the most targeted (and effective) treatment.

The target of choice? Hard to treat illness epicenters like brain tumors.

Scientists will test the world’s first nuclear fusion reactor this summer

April 4, 2021

The International Thermonuclear Experimental Reactor (ITER) will, if things go according to plan, move one step closer to becoming the world’s first functioning nuclear fusion reactor this summer when scientists conduct its inaugural test runs.

Nuclear fusion has, traditionally, been used as the core scientific principle behind thermonuclear warheads. But the same technology that powers our weapons of mass destruction could, theoretically, be harnessed to power our cities. This would be the first fusion reactor capable of producing more energy than it takes to operate.

If we can build and operate fusion reactors safely, we could almost certainly solve the global energy crisis for good. But that’s a big if.

The Battery That Will Finally Unlock Massless Energy Storage

April 4, 2021

It could revolutionize electric vehicles and aircraft.

By Caroline Delbert

Scientists have made a massless structural battery 10 times better than before.
The battery cell performs well in structural and energy tests, with planned further improvements.
Structural batteries reduce weight and could revolutionize electric cars and planes.

In groundbreaking new research, scientists have made a structural battery 10 times better than in any previous experiment.

What’s a structural battery, and why is it such a big deal? The term refers to an energy storage device that can also bear weight as part of a structure—like if the studs in your home were all batteries, or if an electric fence also held up a wall.

In the new paper, researchers from Chalmers University of Technology and KTH Royal Institute of Technology in Sweden reveal how their “massless” structural battery works.RELATED STORYIs the World Ready for the EV Battery Boom?

The main use case is for electric cars, where a literally massive amount of batteries take up a ton of room and don’t contribute to the actual structure of the car. In fact, these cars must be specially designed to carry the mass of the batteries. But what if the frame of the car could hold energy? “Due to their multifunctionality, structural battery composites are often referred to as ‘massless energy storage’ and have the potential to revolutionize the future design of electric vehicles and devices,” the researchers explain.

Ultrasound Imaging Technique Allows Scientists To Read Minds

April 4, 2021

The team successfully tested the method on non-human primates and read out their brains’ intentions.

By Fabienne Lang

A new type of brain-machine interface (BMI) that’s minimally invasive can read out the brain’s intentions using ultrasound technology.

A collaborative team of researchers at Caltech developed the system that can read brain activity corresponding to the planning of movement.

The team’s study was published in the journal Neuron on Monday 22 March.

Neuroscientists working on BMIs in order to map out the brain’s activity to corresponding movements will be having a field day thanks to this new study. Typically, these devices read and interpret brain activity and link it up to a computer or machine.

However, these devices typically require invasive brain surgery, which many patients aren’t willing to partake in.

The news of this new technology, which uses functional ultrasound (fUS) technology accurately maps out neural activity from its source deep within the brain at a resolution of 100 micrometers.

Seattle-based Spaceflight Inc. says it’s won a contract to handle the launch logistics for a pair of NASA satellites that will study the factors behind atmospheric drag.

The twin CubeSats for a mission known as Low-Latitude Ionosphere / Thermosphere Enhancements in Density, or LLITED, are to be lofted into orbit by a SpaceX Falcon 9 rocket around the end of this year. That launch that will mark the first use of Spaceflight’s Sherpa-LTC orbital transfer vehicle, also known as an OTV or space tug.

In January, a different type of Spaceflight space tug, the Sherpa-FX, successfully deployed more than a dozen spacecraft after a Falcon 9 launch. The Sherpa-LTC represents a step above the FX because it has its own in-orbit propulsion system.

The chemical-based thruster system, built for Spaceflight by Benchmark Space Systems, makes it possible for the Sherpa-LTC to shift between different orbital locations. Spaceflight’s mission plan calls for an initial round of satellite deployments, followed by a maneuver that will set the Sherpa up for deploying the LLITED satellites in a different orbit.

“Spaceflight’s full-service offering with our portfolio of Sherpa OTV vehicles greatly increases the scientific opportunities for NASA, universities, and other organizations that require deployments to non-traditional orbital destinations,” Valerie Skarupa, director of government business development for Spaceflight Inc., said in a news release.

Yet another type of OTV, the Sherpa-LTE, will soon make its debut with an electric propulsion system.

Driverless Air Taxis Could Fly Tourists to Restaurants 100-Feet Above the Ground

April 3, 2021

A groundbreaking concept proposes driverless air taxis lifting tourists to restaurants situated 100 feet off the ground – giving an unprecedented experience and view of the Italian wilderness around.

By Mark Bustos

Chinese unmanned aircraft company EHang Holdings are working with architects from the Rome, Italy-based Giancarlo Zema Design Group to turn this lofty vision into a reality. The 100-foot towers – dubbed “Vertiports” by the proponents – are designed to receive the driverless air taxis landing vertically on each roof.

Tourists who will go on the experience will be automatically carried to the raised restaurants. After the dining experience with a panoramic view of the Italian forests, tourists will be ushered by their self-driving vehicles in an equally scenic ride back to their nearby accommodations.

Hitting the reset button: Stanford psychologist says we can build a better normal after the pandemic

April 3, 2021

Instead of emerging from the coronavirus pandemic resilient to crisis and catastrophe, Stanford psychologist Jamil Zaki asks what if we grew stronger because of it?

BY MELISSA DE WITTE

With the end of the pandemic in sight and a longing to return to some resemblance of normalcy, Stanford psychologist Jamil Zakithinks the harrowing experience of the past year is a unique opportunity to reset people’s expectations about many aspects of society. Instead of simply returning to life before the pandemic, what if we could institute new personal and social norms that are more balanced, just and equitable?

Instead of emerging from the coronavirus pandemic merely resilient to crisis and catastrophe, Stanford psychologist Jamil Zaki asks what if we grew stronger because of it?

Zaki believes a concept psychologists call “growth through adversity” may be key to defining what this “new normal” could look like. Instead of resilience – which is about bouncing back from disaster, unchanged – growth through adversity is about finding ways to learn from those hardships and focus on what matters.

“Resilience is staying the course through a storm. Growth is charting a new course,” Zaki said.

He points out that even before the pandemic upended our lives, much of what was considered normal in society was deeply problematic: People had been reporting feeling lonelier and more isolated than ever before. Economic inequality between the rich and poor has been soaring at an alarming rate. And profound racial disparities have marred everything from employment to health and housing.

The pandemic didn’t create these problems. In some cases, it merely exposed them; in others, it exacerbated them.

“A stronger normal holds the adversity we’re going through now up as a mirror, one that can clarify what we’ve been neglecting all along,” said Zaki, associate professor of psychology in Stanford’s School of Humanities and Sciences.

What a Year of WFH Has Done to Our Relationships at Work

April 2, 2021

by Nancy Baym, Jonathan Larson, Ronnie Martin

We know it’s been a while, but do you remember bumping into colleagues in the office hallway, chatting about weekend plans or a big project you’re working on? Do you recall finding yourself in the right place at the right time, giving someone a missing piece of information or introducing a colleague to someone new? If you’re like many people, you may not have realized how much these conversations mattered until you found yourself working from home.

These informal interactions are key to what’s known as social capital — benefits people can get because of who they know. You rely on your social capital every time you’ve hit a dead end and someone pitched in to help you, even though they didn’t have to. It shows up when you need expertise and someone you’d only met once was able to offer it. You also help others build their social capital when you go above and beyond to support them with knowledge, mentoring, or kindness. And the reason you can turn to someone else and offer extra help is that you’ve built a base of familiarity and goodwill through these unplanned interactions that once filled our workdays.
