Electrical engineers at Duke University have devised a fully print-in-place technique for electronics that is gentle enough to work on delicate surfaces including paper and human skin. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages tricked out with patient-specific biosensors.

The techniques are described in a series of papers published online July 9 in the journal Nanoscale and on October 3 in the journal ACS Nano.

“When people hear the term ‘printed electronics,’ the expectation is that a person loads a substrate and the designs for an electronic circuit into a printer and, some reasonable time later, removes a fully functional electronic circuit,” said Aaron Franklin, the James L. and Elizabeth M. Vincent Associate Professor of Electrical and Computer Engineering at Duke.

Scientists at the University of California, Berkeley have used the CRISPR gene-editing tool to give fruit flies an evolutionary advantage they’ve never had before. By making just three small changes to a single gene, the team gave the flies the ability to effectively eat poison and store it in their bodies, protecting themselves from predators in the process.

Milkweed is a common plant that’s toxic to most animals and insects – but the monarch butterfly flies in the face of that plant’s defenses. The bug has evolved the ability to not only thrive on the poisonous plant, but turn it to its own advantage. It stores the toxins in its body, making it poisonous to any predators that might try to eat it.

And now, the UC Berkeley researchers have given fruit flies that ability for the first time. CRISPR has been used to edit the genes of insects, mammals and even humans, but the team says this is the first time a multicellular organism has been edited to endow it with new behaviors and adaptations to the environment. In this case, that means a new diet and a new defense mechanism against predators.

Drew Endy almost can’t talk fast enough to convey everything he has to say. It’s a wonderfully complex message filled with nuance, a kind of intricate puzzle box being built by a pioneer of synthetic biology who wants to fundamentally rejigger the living world.

Endy heads a research team at Stanford that is, as he puts it, building genetically encoded computers and redesigning genomes. What that means: he’s trying to engineer life forms to do useful things. Just about anything could come out of this toolkit: new foods, new materials, new medicines. So you are unlikely to find anyone who is more optimistic than he is about the potential for synthetic biology to solve big problems.

That’s what makes Endy so compelling when he worries about how the technology is being developed. Perhaps more than anyone else working in synthetic biology, Endy has tried to hold the community to account.

Too many hospitals provide medications according to the practicalities of their staffing schedules rather than the ideal dosing times for their patients, according to a new study led by experts at Cincinnati Children’s.

The study, published Oct. 1, 2019, in PNAS, was led by David Smith, MD, Ph.D., Divisions of Pediatric Otolaryngology and Pulmonary Medicine; Marc Ruben, Ph.D.; and John Hogenesch, Ph.D., Co-Director, Center for Circadian Medicine at Cincinnati Children’s.

The study examined the daily distribution of approximately 500,000 doses of 12 drugs in 1,486 inpatients at a major U.S. children’s hospital.

Biomedical engineers at Duke University have devised a machine learning approach to modeling the interactions between complex variables in engineered bacteria that would otherwise be too cumbersome to predict. Their algorithms are generalizable to many kinds of biological systems.

In the new study, the researchers trained a neural network to predict the circular patterns that would be created by a biological circuit embedded into a bacterial culture. The system worked 30,000 times faster than the existing computational model.

To further improve accuracy, the team devised a method for retraining the machine learning model multiple times to compare their answers. Then they used it to solve a second biological system that is computationally demanding in a different way, showing the algorithm can work for disparate challenges.

CRISPR Gene-Editing Shows Promise As HIV Cure, Research Shows : Shots — Health News Researchers safely used CRISPR gene-editing techniques in a patient with HIV. The research provides evidence the approach may be promising for treating HIV infection.

Despite this economic pressure, rural America remains one of our nation’s most fertile regions, and recent advances in biotechnology are making it easier than ever to sustainably grow new kinds of valuable goods, from biopharmaceuticals to biomaterials. With the right strategic investments, rural America could see a biotech “bloom.”

I propose a Bio-Belt stretching through middle America to bring new skills and high-paying jobs to communities that desperately need them. This initiative would bolster investment in biotechnology training, education, infrastructure and entrepreneurship in rural areas in order to develop new, sustainable sources of income.

The Bio-Belt is about much more than biofuel. Fermentation is an increasingly powerful force for converting sugar and other forms of biomass into value-added goods—all through the rational design of cells that can be sustainably grown wherever land is abundant.

The fruit flies in Noah Whiteman’s lab may be hazardous to your health.

Whiteman and his University of California, Berkeley, colleagues have turned perfectly palatable fruit flies—palatable, at least, to frogs and birds—into potentially poisonous prey that may cause anything that eats them to puke. In large enough quantities, the flies likely would make a human puke, too, much like the emetic effect of ipecac syrup.

That’s because the team genetically engineered the flies, using CRISPR-Cas9 gene editing, to be able to eat milkweed without dying and to sequester its toxins, just as America’s most beloved butterfly, the monarch, does to deter predators.

Scientists have unraveled the biological mechanisms behind what they describe as the extraordinary “superpower” ability of jellyfish to regenerate body parts.

Jellyfish are primitive animals which evolved in the oceans around 600 million years ago. Part of the reason for their evolutionary success is that some species are able to grow back tissue that has been lost—a trait that is rare in the animal kingdom.

To learn more about this poorly understood ability, a team of researchers from Tohoku University in Japan investigated the biology of a jellyfish species known as Cladonema pacificum—which has tentacles that spread out like tree branches—for a study published in the journal PeerJ.
