The Challenges of Growing Plants in Space
Sustained space travel and colonization will depend on the ability to grow food in extra-terrestrial environments. The fact that plants evolved on earth with cues from gravity, photoperiod, barometric pressure and other signals means that plants growing on space stations or other planets will face unique stresses, never previously encountered. Add to this the challenges of watering plants in microgravity, a dependence on artificial lighting, and limited access to crop protection and fertilization strategies, and the ability to produce crops in space is a realistic limiter of long-term human colonization of space. Dr. Anna-Lisa Paul has studied plant biology in space and in extreme earth environments to learn about how plants adapt to these challenges, and even how humans might have to adapt to care for them.

Tiredness: Time for DNA Repair!
We all know the feeling of tiredness, but what causes the urge to sleep? Prof. Lior Appelbaum discusses the link between sleepiness and DNA damage, as sensed through the accumulation of a protein known as PARP1. PARP1 is well known for its roles in DNA repair. Prof. Appelbaum’s team has examined PARP1 accumulation in animal models and shown strong evidence that the desire to sleep is triggered by DNA damage, and the desire to sleep involves action by PARP1. The conclusion is that tiredness should not be ignored, as it is a signal that there is some DNA damage to be corrected, and may play a role in long-term brain health.# COLABRATalking Biotech is brought to you by Colabra – an R&D platform that brings your lab’s world-changing research together in one shared space.

Reprogramming T-Cells for Immunotherapies
T Cells are the body’snatural defenders against pathogens. In the past they have been reprogrammed to recognize specific surface antigens of cancer cells to attack and destroy them. The approach has worked well against a variety of cancers. The limitation is that they addition of genetic material is limited by transfer techniques. This episode of the Talking Biotech Podcast discusses the new approach with Dr. Ken Drazan of Arsenal Bio. They have devised a strategy to place genetic material into T-cells from an afflicted patient that can now work against the disease in question. The approach uses gene editing, adding genetic material to T cells that allows them to recognize specific antigens, such as those associated with ovarian cancer.Follow on Twittter: @ArsenalBio# COLABRATalking Biotech is brought to you by Colabra – an R&D platform that brings your lab’s world-changing research together in one shared space.

Breeding Future Olives
Olives have a prominent role in the production of aromatic healthy culinary oils and brined olives for the table. Olive oil production occurs worldwide on old-growth orchards that are subject to a number of modern production challenges. Disease, pests, climate change and other issues threaten sustainable production. Today’s guest is Prof. Lorenzo Leon, an olive breeder from IFAPA in Cordoba, Spain. He has taken on the mantle of creating the next generation of superior olive cultivars. We discuss the challenges of olive breeding, the protracted timeline, and the fact that his crosses today may result in something in the field decades down the road. We discuss modern genetic tools and their implementation. The discussion is a great appreciation of plant breeders, their important job, and the challenges they face.Follow Dr. Leon on Twitter: @OliveBreeding# COLABRATalking Biotech is brought to you by Colabra – an R&D platform that brings your lab’s world-changing research together in one shared space.

Insulin from Synthetic Biology
Thirty million Americans depend on daily doses of insulin to stay alive. This small protein hormone is responsible for the regulation of blood sugar, and plays a key role in all aspects of physiology, as well as long-term effects on health. Despite its importance, the vast majority of insulin is produced off shore, leaving it vulnerable to supply chain disruptions that could be hazardous for many Americans. Domestic production is hindered by a variety of barriers, from production to regulatory. Cameron Owen is the CEO and Co-Founder of rBIO, and they are using a specially designed E. coli bacterium that focuses strictly on insulin production. This streamlining of the process around bacteria that commit the majority of resources into insulin production leads to minimizing side reactions and higher yields of the desired product. Making the production process more efficient means that this critical hormone may be produced at a lower price and without fear of supply chain production.Follow rBIO on twitter at @rBio_pharma# COLABRATalking Biotech is brought to you by Colabra – an R&D platform that brings your lab’s world-changing research together in one shared space.

Rediscovery of New Cancer Drugs
Drug pipelines are thick with novel compounds that may have an effect on our most insidious diseases. However, most either fail early trials or are withdrawn because companies don’t see the return on investment of driving them forward. These shelved compounds still may have important roles in treating orphan diseases. The Children’s Tumor Foundation identifies these compounds lost to corporate expectations and re-analyzes them for therapeutic potential for other indications. Dr. Annette Bakker describes the process, the potential and the promise of compounds already identified in this partnership with pharmaceutical companies– testing their throwaways for new applications.# COLABRATalking Biotech is brought to you by Colabra – an R&D platform that brings your lab’s world-changing research together in one shared space.

Evidence that Modern Birds are Dinosaurs
The classical assumption was that the modern dinosaur lineage led directly to today’s reptiles. However, a growing suite of evidence has shown that modern birds more closely emulate prehistoric creatures. Today’s guests are Profs Alexander Vargas (University of Chile) and Joao Bothelo (Catholic University of Chile). Their work on comparative anatomy in embryos has unveiled additional similarities between birds and dinosaurs, and pharmacological and molecular evidence has shown that chicken embryos can be affected to present subtle dinosaur-like traits. Their work provides additional evidence that modern birds are actually modern avian dinosaurs.
