Scientists Find New Way To Rejuvenate Ageing Human Cells

 



Researchers have unveiled a promising technique that revives ageing human cells by enhancing mitochondrial activity, offering a potential pathway to treat degenerative and age-related diseases. The breakthrough centres on improving the energy-producing ability of cells that naturally weaken over time.

Focus on Mitochondria and Ageing

The study by Texas A&M University highlights how mitochondria, the cell’s energy generators, decline in efficiency with age, contributing to heart, brain and metabolic disorders. Restoring mitochondrial function has long been considered key to slowing biological ageing at the cellular level.

Nanoflower Technology Boosts Cellular Energy

Scientists developed microscopic “nanoflowers” from molybdenum disulfide. These particles, shaped like tiny blossoms, contain pores that absorb harmful reactive oxygen species. By reducing oxidative stress, the nanoflowers activate genes that trigger the formation of new mitochondria in human stem cells, significantly improving their vitality.

Healthier Cells Revive Weaker Neighbours

The energised stem cells can transfer healthy mitochondria to nearby damaged cells, effectively restoring their activity. Researchers describe this as akin to replacing depleted batteries rather than merely recharging them. The method does not require drugs or genetic modification and could serve as a foundation for safe regenerative therapies.

Potential for Future Therapeutic Use

The technique nearly doubled the natural transfer of mitochondria between cells, with smooth muscle cells showing three- to fourfold growth improvements. Heart cells injured by chemotherapy also recorded higher survival rates. Scientists believe the approach could be adapted to support cardiovascular repair, treat muscular dystrophy and rejuvenate tissues across the body, marking the beginning of broader regenerative possibilities.

Uttrakhand Forest Department Establishes Mahabharata Vatika

Image
  The Uttarakhand Forest Department has established two gardens in Haldwani, showcasing plant species referenced in ancient Indian epics. These gardens, named Ramayana Vatika and Mahabharata Vatika, aim to highlight the ecological wisdom embedded in these texts. Mahabharata Vatika Overview Mahabharata Vatika spans one acre and features 37 plant species mentioned in the epic. Chief Conservator of Forests Sanjeev Chaturvedi emphasised the research behind selecting these species. The garden features important plant species such as: Ecological Significance The garden puts stress on the importance of forests as depicted in the Mahabharata. It references the Vana Parva, which discusses tree planting and wildlife conservation . The epic highlights the mutual dependence of tigers and forests, a concept vital to contemporary conservation efforts. Cultural Connections Chaturvedi brought into light that the Mahabharata teaches the spiritual significance of planting trees. He mentioned Bhish...

CAR T-Cell Therapy for Cancer

Image
  India has recently made strides in cancer treatment with the introduction of CAR T-cell therapy . The results from the first clinical trials have been published in The Lancet, showcasing a remarkable success rate. This therapy is a game changer for patients with blood cancers. It offers hope to those who have exhausted other treatment options. What is CAR T-Cell Therapy? CAR T-cell therapy, or chimeric antigen receptor T-cell therapy, is an innovative treatment that harnesses the body’s immune system. It trains T-cells to target and destroy cancer cells. This therapy is specifically designed for certain blood cancers. It is particularly beneficial for patients whose cancer has relapsed or failed to respond to standard treatments. Clinical Trial The clinical trials reported a response rate of nearly 73%. This indicates that number of patients benefited from the treatment. The trials also provided critical data on survival rates for patients with acute lymphoblastic leukaemia and l...

PEN-Plus Strategy Enhances NCD Care in Africa

Image
  In recent years, the burden of non-communicable diseases (NCDs) has escalated in the WHO African Region. A report released by the World Health Organization (WHO) Africa assessed the PEN-Plus approach that aims to decentralise critical health services for severe NCDs. Since its adoption, twenty African countries have improved access to essential care, addressing public health threat. About Non-Communicable Diseases (NCDs) NCDs are chronic diseases that are not caused by infectious agents. They progress slowly and result from a mix of genetic, environmental, and behavioural factors. Common NCDs include heart disease, diabetes , and cancers. Globally, NCDs account for 71% of deaths. In Africa, they represent portion of mortality, ranging from 27% to 88%. The PEN-Plus Approach The PEN-Plus model complements the WHO’s Package of Essential Non-communicable Disease interventions. It focuses on managing severe NCDs at the primary healthcare level. Originally developed in Rwanda, PEN-Plu...
