Walking Thoughts

  One of the things I am proudest of in my career is having built something that did not previously exist. I joined a two-person engineering start-up as its first Net Zero specialist and was given the opportunity to develop a new proposition around carbon reduction. I turned my experience in embodied carbon, Lean, management and engineering into a portfolio of commercially viable services, won client work, built the delivery capability and recruited and developed the people needed to deliver it. As demand grew, I established the processes and management structures required to support the organisation, ultimately helping transform a one-person engineering training business into a 20-person carbon reduction and sustainability consultancy. What particularly motivates me about leadership is not simply managing people, but creating the conditions in which talented people can do their best work. I developed my original team to the point where two senior managers were able to take over my...

  Today is the anniversary of the day NASA lost a $125 million spacecraft to a unit conversion. Mars Climate Orbiter disappeared because one engineering team worked in imperial units while another worked in metric. Somewhere, Dr Foy is still saying:  “Units and dimensions, class…” Dr Foy was my physics teacher and, as a child, my role model. Elegant, brilliant and prone to regaling us with stories from her PhD days. I went on to study physics at university, before evolving into a chemical engineer via biochemistry and, eventually, a PhD of my own. (See what I did there? No? Never mind. It amused me.) The right role model can change the trajectory of a student. A great mentor can do the same for someone at the beginning of their career. And apparently, some lessons have a remarkably long shelf life. Units matter. Those who have worked for me or been unfortunate enough to be mentored by me will scarcely believe I’m  still  banging on about this. But I see it constantly...

  Insulin was discovered in  Toronto  in 1921  because a unique mix of an intuitive surgeon's specific hypothesis, a well-equipped university physiology laboratory, and an ethical decision to share the patent made the breakthrough possible. [ 1 ,  2 ] Why Toronto in 1921? The Right Idea:  Canadian surgeon  Frederick Banting  had a sudden insight in late 1920  that tying off pancreatic ducts would destroy digestive enzymes before they broke down the internal secretion needed to control blood sugar.  [ 1 ,  2 ,  3 ] The Right Institutional Support:   Banting  took his idea to  John J. R. Macleod , a leading professor of physiology at the  University of Toronto .  Macleod  provided  Banting  with a proper laboratory, experimental dogs, and medical student  Charles Best  as an assistant for the summer of 1921 .  [ 1 ,  2 ,  3 ] Biochemical Expertise:  When...

 Yesterday, I attended a fascinating webinar on powder dispersion. I had originally been rejected for attending the webinar, which was a new experience. But my interest in the subject is genuine, withpowdered zero valent iron taking centre stage during my PhD research.  Dr. Jacob provided an expert view Of the physical characteristics of different powders, Including two of my favourites  - metals and activated carbon. These are very different physical properties, including their relative densities and absorption capabilities. For me powdered zero iron acted as an electron donor in a redox remediation of contaminated waste water. And my previous love activated carbon is applied in drinking water Treatment to add sob organics and so treating taste. Other factors that Dr Jacob covered with the health and safety factors and physical losses. Well, thanks to Dr Jacob for a fascinating webinar. Let me know when you have turned a rejection around to end in a positive result?

  Scientists just discovered that peptides in axolotl mucus kills breast cancer cells naturally, without harming healthy tissue. And it also destroys drug-resistant MRSA bacteria Published in the journal PLOS ONE, the study reveals that specific antimicrobial peptides (AMPs) extracted from the axolotl's protective slime successfully destroyed methicillin-resistant Staphylococcus aureus (MRSA).  Even more remarkably, three of these peptides selectively triggered programmed cell death in breast cancer cells while completely sparing healthy breast tissue, offering an incredibly precise new pathway for targeted therapies. By gently massaging captive-bred axolotls to collect their mucus, scientists identified and synthesized 22 potential peptide candidates, finding that their unique chemical structures allow them to puncture bacterial cell walls and disrupt oncogenes in cancer cells. This natural defense mechanism is significantly harder for pathogens to develop resistance against ...
