HOUSE OF SUNSCREEN: INNOVATIONS IN SUNCARE

Meet your sunscreen dream.

“My first sunscreen was the one with the little girl and the dog pulling her swimsuit off,” recalls Gaby Giron, Sephora Assistant Skincare Merchant. “I just remember the smell. It was definitely memorable, but not in the best sense.” Thankfully, the days of chalky, greasy, weird-smelling sun protection are over—along with excuses not to wear it. New innovations in formulas and formats now offer a wealth of solutions to old problems, and, often, additional skincare benefits. Read on for the answer to your sunscreen dreams.  MELISSA LANE

Art in Engineering Revealed

Many people think that applying science and math to real-world problems gives you engineering. That’s true, of course, and from the wide field of intellectual pursuit every year blooms seemingly physics-defying bridges, technologies that operate at the nanoscale, amazingly capable robots and vehicles that take us to space or the deepest depths of the ocean. But often lost in this utilitarian view of engineering is the fact that it can also give rise to a whole lot of art, too. 

The University of Cambridge’s engineering department saw the charm in its community’s work and put out a call for the most visually stunning images in a photography competition sponsored by optics maker Zeiss. Now the department has put them on display for us to ogle. 

“I love the way in which the essence of engineering can be captured in a single beautiful image – these intriguing works of art convey wonderful stories of determined engineers battling to crack real-world problems and finding the most elegant answers,” said department research director Philip Guildford, one of the competition’s judges.

Using the Power of Space to Fight Cancer

From cancer research to DNA sequencing, the International Space Space is proving to be an ideal platform for medical research. But new techniques in fighting cancer are not confined to research on the space station. Increasingly, artificial intelligence is helping to “read” large datasets. And for the past 15 years, these big data techniques pioneered by our Jet Propulsion Laboratory have been revolutionizing biomedical research.

Microgravity Research on Space Station

On Earth, scientists have devised several laboratory methods to mimic normal cellular behavior, but none of them work exactly the way the body does. Beginning more than 40 years ago aboard Skylab and continuing today aboard the space station, we and our partners have conducted research in the microgravity of space.  In this environment, in vitro cells arrange themselves into three-dimensional groupings, or aggregates. These aggregates more closely resemble what actually occurs in the human body. Cells in microgravity also tend to clump together more easily, and they experience reduced fluid shear stress – a type of turbulence that can affect their behavior. The development of 3D structure and enhanced cell differentiation seen in microgravity may help scientists study cell behavior and cancer development in models that behave more like tissues in the human body.

In addition, using the distinctive microgravity environment aboard the station, researchers are making further advancements in cancer therapy. The process of microencapsulation was investigated aboard the space station in an effort to improve the Earth-based technology. Microencapsulation is a technique that creates tiny, liquid-filled, biodegradable micro-balloons that can serve as delivery systems for various compounds, including specific combinations of concentrated anti-tumor drugs. For decades, scientists and clinicians have looked for the best ways to deliver these micro-balloons, or microcapsules, directly to specific treatment sites within a cancer patient, a process that has the potential to revolutionize cancer treatment.

A team of scientists at Johnson Space Center used the station as a tool to advance an Earth-based microencapsulation system, known as the Microencapsulation Electrostatic Processing System-II (MEPS-II), as a way to make more effective microcapsules. The team leveraged fluid behavior in microgravity to develop a new technique for making these microcapsules that would be more effective on Earth. In space, microgravity brought together two liquids incapable of mixing on Earth (80 percent water and 20 percent oil) in such a way that spontaneously caused liquid-filled microcapsules to form as spherical, tiny, liquid-filled bubbles surrounded by a thin, semipermeable, outer membrane. After studying these microcapsules on Earth, the team was able to develop a system to make more of the space-like microcapsules on Earth and are now performing activities leading to FDA approval for use in cancer treatment.  

In addition, the ISS National Laboratory managed by the Center for the Advancement of Science in Space (CASIS) has also sponsored cancer-related investigations.  An example of that is an investigation conducted by the commercial company Eli Lilly that seeks to crystallize a human membrane protein involved in several types of cancer together with a compound that could serve as a drug to treat those cancers. 

“So many things change in 3-D, it’s mind-blowing – when you look at the function of the cell, how they present their proteins, how they activate genes, how they interact with other cells,” said Jeanne Becker, Ph.D., a cell biologist at Nano3D Biosciences in Houston and principal investigator for a study called Cellular Biotechnology Operations Support Systems: Evaluation of Ovarian Tumor Cell Growth and Gene Expression, also known as the CBOSS-1-Ovarian study. “The variable that you are most looking at here is gravity, and you can’t really take away gravity on Earth. You have to go where gravity is reduced." 

Crunching Big Data Using Space Knowledge

Our Jet Propulsion Laboratory often deals with measurements from a variety of sensors – say, cameras and mass spectrometers that are on our spacecraft. Both can be used to study a star, planet or similar target object. But it takes special software to recognize that readings from very different instruments relate to one another.

There’s a similar problem in cancer research, where readings from different biomedical tests or instruments require correlation with one another. For that to happen, data have to be standardized, and algorithms must be “taught” to know what they’re looking for.

Because space exploration and cancer research share a similar challenge in that they both must analyze large datasets to find meaning, JPL and the National Cancer Institute renewed their research partnership to continue developing methods in data science that originated in space exploration and are now supporting new cancer discoveries.

JPL’s methods are leading to the development of a single, searchable network of cancer data that researcher can work into techniques for the early diagnosis of cancer or cancer risk. In the time they’ve worked together, the two organizations’ efforts have led to the discovery of six new Food and Drug Administration-approved cancer biomarkers. These agency-approved biomarkers have been used in more than 1 million patient diagnostic tests worldwide.
