To test the interaction between senolytic removal of senescent cells and cellular reprograming, we designed a model combining these two interventions in an inducible overexpression system in Drosophila. First, we used the four Yamanaka factor based OKSM approach as this had been previously shown to induce pluripotent stem cells in mice [7], humans [29 – 31] and non-mammalian vertebrate and invertebrate species [32]. To make a senolytic factor for Drosophila, we took advantage of the mouse sequence (FOXO4-DRI [22]) to design an orthologous peptide based on the Drosophila foxo (forkhead box, sub-group O) gene [33]. We then characterized effects of these two interventions independently as well as in combination.

We began by looking at the effect of OKSM and Sen on stem cells in an intestinal stem cell (ISC) model [34, 35]. We chose to investigate phenotypic effects specifically in the digestive system of Drosophila (Supplementary Figure 1). As in mammals, the Drosophila gastric lining has a high turnover of cells which is enabled by stem cell pools that replenish the epithelia [34]. Age-dependent loss of stem cells and degradation of barrier function has been shown to contribute to age-dependent functional decline and mortality in Drosophila [36]. The Drosophila gut is composed of four cell types: enterocytes (ECs or absorptive cells), enteroendocrine (EEs or secretory cells), enteroblasts (EBs or transit amplifying cells) and intestinal stem cells (ISCs).

Biotech company Mogling Bio has successfully has completed its first seed investment round with a sole investor, Kizoo Technology Capital.

Mogling Bio is developing new pharmacological approaches to rejuvenate old stem cells of the hematopoietic (blood cell formation) system.

Ageing causes stem cells to lose their normal structure by increased activity of the protein CDC42. Normalising CDC42 activity can restore structure, order and functionality in those aged stem cells.

The Aging and Drug Discovery Conference (ARDD) 2022 is pleased to present Alex Zhavoronkov from Insilico, with the talk A case study of the application of Pharma. AI platform for discovery and development of dual-purpose therapeutics targeting aging and disease.

Held in Copenhagen at the glorious Ceremonial Hall, this meeting gathers the most prominent figures of the aging and longevity research field, from scientists to clinicians, investors, developers, and everything in between. The fast growth of the conference is evidence of its great quality of it. In 2022 we had around 400 people on-site, and many others joined through the web.

A compound that both inhibits the MRSA superbug and renders it more vulnerable to antibiotics in lab experiments has been discovered by researchers at the University of Bath in the UK.

Antibiotic resistance poses a major threat to human health around the world, and Staphylococcus aureus has become one of the most notorious multidrug-resistant pathogens. Led by Dr. Maisem Laabei and Dr. Ian Blagbrough at the University of Bath, scientists have discovered a compound that both inhibits the Methicillin-resistant Staphylococcus aureus (MRSA) superbug and renders it more vulnerable to antibiotics.

Staphylococcus aureus (staph) is a type of bacteria found on people’s skin. Staph bacteria are usually harmless, but they can cause serious infections that can lead to sepsis or death. Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of staph infection that is difficult to treat because of resistance to some antibiotics.

Short clip of Michael Levin, an American developmental and synthetic biologist at Tufts University, talking about Planarian and their capacity to regenerate their organs indefinetely, which makes then biologically immortal.

The remarks where given during a fascinating three-hour-long conversation with Lex Fridman that was aired on october 1st, 2022.

Biohacking is a relatively new practice that focuses on studying and learning about living beings and looking for ways to improve their function.

Scientists including an Oregon State University materials researcher have developed a better tool to measure light, contributing to a field known as optical spectrometry in a way that could improve everything from smartphone cameras to environmental monitoring.

The study, published today in Science, was led by Finland’s Aalto University and resulted in a powerful, ultra-tiny spectrometer that fits on a microchip and is operated using artificial intelligence.

The research involved a comparatively new class of super-thin materials known as two-dimensional semiconductors, and the upshot is a proof of concept for a spectrometer that could be readily incorporated into a variety of technologies—including quality inspection platforms, security sensors, biomedical analyzers and space telescopes.

“We are very pleased that we can now start with the first activities to stimulate and consolidate cellular agriculture in the Netherlands,” said Ira van Eelen, CEO of KindEart. Tech and a board member of Cellular Agriculture Netherlands. “With this we can guarantee that the Netherlands remains the ideal place for cellular agriculture to thrive. We have a rich history in cellular agriculture and are a global leader in biotechnology, alternative proteins and food innovation. Supported by this visionary leadership that the Dutch government is showing again today, we will expand our team in the coming months and roll out the first activities around public research, scaling up, and education.”

Indeed, the Netherlands has been demonstrating considerable progress in developing cultured meat. In July, for example, Dutch company Meatable revealed its first lab-grown sausages, which are expected to go on sale to consumers by 2025. The addition of €60 million in government funding will make the Netherlands an even more attractive location for companies in the sector.

Currently a niche and miniscule part of the overall food market, cultured meat has potential to become another “exponential” technology – much like the semiconductor industry, solar energy, genome sequencing, and so on. The benefits in terms of animal welfare, climate change, food safety, antibiotic resistance, land and water usage could be substantial.
