Eric Schmidt told a conference crowd that Silicon Valley is obsessed with biology because it’s the perfect “marriage” with tech right now.

This week a new group of astronauts launched from the Baikonur Cosmodrome in Kazakhstan headed for the International Space Station. The three new ISS crew members, Jessica Meir of NASA, Oleg Skripochka of Roscosmos, and Hazza Ali Almansoori of the Emirati Space Agency docked with the station several hours later, temporarily taking the population of the station to nine people. That marks the largest crew aboard the ISS since 2015, but members of previous Expedition team 60 will be returning to Earth in around a week.
While the transferring of astronauts to and from the ISS is fairly standard for space agencies these days, there was something special about this mission. Astronaut Christina Koch was looking forward to being joined by her best friend and fellow NASA astronaut Jessica Meir, so she decided to capture an image of the incoming craft from her perspective on board the ISS. The result is the stunning photo above, showing the ghostly trails from the first stage and the cloud of vapor around the craft.
The astronauts traveled aboard a Soyuz MS-15 spacecraft, docking at the station’s Zvezda service module six hours after launch. The crew will stay aboard the ISS for at least six months and will be working on scientific projects in varied fields including biology, physical sciences, and the development of new technologies. They will also perform upgrades to the stations including installing new lithium-ion batteries which collect power from the station’s solar panels, part of an ongoing project to update the ISS’s power system.
The Columbia team behind the revolutionary 3D SCAPE microscope announces today a new version of this high-speed imaging technology. In collaboration with scientists from around the world, they used SCAPE 2.0 to reveal previously unseen details of living creatures—from neurons firing inside a wriggling worm to the 3D dynamics of the beating heart of a fish embryo, with far superior resolution and at speeds up to 30 times faster than their original demonstration.
These improvements to SCAPE, published today in Nature Methods, promise to impact fields as wide ranging as genetics, cardiology and neuroscience.
Why is having faster, 3D imaging so valuable? “The processes that drive living things are dynamic and ever-changing, from the way an animal’s cells communicate with one another, to how a creature moves and changes shape,” said Elizabeth Hillman, Ph.D., a principal investigator at Columbia’s Mortimer B. Zuckerman Mind Brain Behavior Institute and the paper’s senior author. “The faster we can image, the more of these processes we can see—and imaging fast in 3D lets us see the whole biological system, rather than just a single plane, offering a clear advantage over traditional microscopes.”
Caltech scientists have discovered a new species of worm thriving in the extreme environment of Mono Lake. This new species, temporarily dubbed Auanema sp., has three different sexes, can survive 500 times the lethal human dose of arsenic, and carries its young inside its body like a kangaroo.
Mono Lake, located in the Eastern Sierras of California, is three times as salty as the ocean and has an alkaline pH of 10. Before this study, only two other species (other than bacteria and algae) were known to live in the lake—brine shrimp and diving flies. In this new work, the team discovered eight more species, all belonging to a class of microscopic worms called nematodes, thriving in and around Mono Lake.
The work was done primarily in the laboratory of Paul Sternberg, Bren Professor of Biology. A paper describing the research appears online on September 26 in the journal Current Biology.
Food security is one of the biggest challenges we’re facing as we move further into this century. Changing climate, pests, stress on water and land are all limiting our ability to produce sufficient amounts of food. making food production an issue.
Synthetic biology offers ways to help produce and supply enough safe and nutritious food sustainably for the estimated 9 billion people that will inhabit the planet by 2050.
Here are a few ways how.

Humanist and technoscientific notions of progress have been (mis)used to classify human and nonhuman life forms into hierarchical categories, thereby reducing the complexities of life stories into a linear account of development and innovation. At the same time, critical reflections on key concepts of modernist, Eurocentric and industry-driven concepts of time and historicity and, more forcefully perhaps, new findings in evolutionary biology and physics, have produced alternative narratives, sometimes with a reconsideration of premodern understandings of temporality like, for example, Gilles Deleuze ’s rereading of Leibniz in The Fold.[1] The modernist conception of History (with a capital H) as both an empirical reality and a specific disciplinary and disciplining knowledge [2] has thus become just one possible manifestation within a plurality of histor ies conditioned by socio-cultural particularities that honour the experience of bodies that, voluntarily or not, live outside re/productive timelines, for example.
An increasing number of researchers as well as artists are no longer interested in the taking and making time and space as human universals but in genealogies, intersections, “multiple modernities”[3] and the coexistence of non-simultaneous phenomena in the era of globalization, asymmetrical power relations and technoculture. Moreover, post-anthropocentric thinking and creativity, fostered in posthumanist discourse (including new materialism, speculative realism, object-oriented ontology, neocybernetic systems theory, etc.), also increasingly attends to nonhuman temporalities and how these are entangled, often in conflicting ways, with human time. Such considerations include the vexing question of how emancipatory goals of progressive social trans/formation and justice can be envisaged, let alone obtained, if we can no longer ground our theories and political practices in enlightened narratives of humanist progress and liberation.
TVs and radios blare that “artificial intelligence is coming,” and it will take your job and beat you at chess.
But AI is already here, and it can beat you — and the world’s best — at chess. In 2012, it was also used by Google to identify cats in YouTube videos. Today, it’s the reason Teslas have Autopilot and Netflix and Spotify seem to “read your mind.” Now, AI is changing the field of synthetic biology and how we engineer biology. It’s helping engineers design new ways to design genetic circuits — and it could leave a remarkable impact on the future of humanity through the huge investment it has been receiving ($12.3b in the last 10 years) and the markets it is disrupting.
Evidence that quantum searches are an ordinary feature of electron behavior may explain the genetic code, one of the greatest puzzles in biology.
FRANCE’S tourist beaches are being overrun with toxic slime which experts say can kill sunbathers and swimmers within seconds.
The green algae releases poisonous gases when trodden on causing those nearby to faint and suffer cardiac arrest, say reports.
At least three people and dozens of animals have already died, but some fear other deaths may have been mistakenly passed off as drownings.
