The pursuit of a longer life may currently be trending for tech bros, but the notion of a fountain of youth, or even immortality, has intrigued people for millennia. Yet, some of the more evidence-based methods to increase longevity, such as dieting, are decidedly unpleasant to maintain over time.
Engineers at MIT say they developed a flexible drug delivery patch for promoting healing and tissue regeneration after heart attacks.
The human genome is riddled with relics of viral infections—bits of DNA from viruses that have been inserted in human DNA over millions of years and never left. Most are silent but some have taken on functional roles, particularly in organs that evolve relatively rapidly, including the placenta.
A pioneering patient-reported outcome tool, developed by health care company Observia with the support of Kingston University, has shown significant promise in predicting the risk of a patient with chronic conditions not following their treatment plan, while also uncovering the deep psychological and social reasons driving the patient’s decision making.
The Korea Research Institute of Standards and Science (KRISS) has developed a retina-mimicking eye phantom that faithfully replicates the structural layers and microvascular network of the human retina. This innovation provides a new reference for objectively evaluating and calibrating ophthalmic imaging devices, paving the way for more accurate and reliable diagnosis of retinal diseases.
A poorly characterized protein, historically thought to be a chaperon or enzyme, may actually be a key player in prostate cancer. In a systematic CRISPR screen, scientists from Arc Institute, UCSF, and the Fred Hutchinson Cancer Center have identified PTGES3, known as the third prostaglandin E synthase protein, as an unexpected regulator of the androgen receptor.
In order to understand brain diseases, neuroscientists try to untangle the intricate nerve fiber labyrinth of our brain. Before analyzing brain tissue under a microscope, it is often soaked in paraffin wax to achieve high-quality sections. However, accurately mapping the densely packed nerves inside wax-treated brain slices was so far not possible.
Caricature artists exaggerate distinctive features of an individual, deepening a cleft chin or multiplying freckles. Yale researchers have now applied a similar approach to maps of neural connections, emphasizing individual differences to see if they yield useful information.
MIT researchers created microscopic wireless electronic devices that travel through blood and implant in target brain regions, where they provide electrical stimulation.
Cultured from induced pluripotent stem cells, “miBrains” integrate all major brain cell types and model brain structures, cellular interactions, activity, and pathological features.
