It wasn’t until Albert Einstein that we developed a more sophisticated mathematical understanding of time and space that allowed physicists to probe deeper into the connections between them. In their endeavors, physicists also discovered that seeking the origin of time forces us to confront the origins of the universe itself.
What exactly is time, and how did it come into being? Did the dimension of time exist from the moment of the Big Bang, or did time emerge as the universe evolved? Recent theories about the quantum nature of gravity provide some unique and fantastic answers to these millennia-old questions.
Periodic circumferential cytoskeletons support biological tube formation. Here, the authors show that self-assembled actin nanoclusters undergo biased fusion and develop into periodic cables in response to the membrane anisotropy of the expanding Drosophila tracheal tube.
Ten years ago, neuroscientist Sergiu Pasca was just getting his lab up and running. He had not yet published the research for which he would become renowned: a novel technique for growing 3D clusters …

“If we give it to aged mice, they rejuvenate. If we give it to young mice, they age slower. No other therapy right now can do this.”
The fountain of youth has eluded explorers for ages. It turns out the magic anti-aging elixir might have been inside us all along.
Cold Spring Harbor Laboratory (CSHL) Assistant Professor Corina Amor Vegas and colleagues have discovered that T cells can be reprogrammed to fight aging, so to speak. Given the right set of genetic modifications, these white blood cells can attack another group of cells known as senescent cells. These cells are thought to be responsible for many of the diseases we grapple with later in life.
Senescent cells are those that stop replicating. As we age, they build up in our bodies, resulting in harmful inflammation. While several drugs currently exist that can eliminate these cells, many must be taken repeatedly over time.
“Permutation City” by Greg Egan explores the nature of reality, consciousness, and existence. Set in a future where people can upload their consciousness into virtual realities, known as “Autoverse.” A software engineer, René Barjavel, becomes embroiled in a complex and mind-bending exploration of identity and the nature of existence as he grapples with the implications of living in a world where reality itself may be a simulation.
