Earth is on its way to the biggest mass extinction since the dinosaurs, scientists warn
Three scientists who have studied extinctions of thousands of species of vertebrates believe so, though others are skeptical of the doomsday-like findings.
“This is the case of a biological annihilation occurring globally, even if the species these populations belong to are still present somewhere on Earth,” Rodolfo Dirzo, the study’s co-author and a Stanford University biology professor, said in a news release.
The researchers analyzed 27,600 species of birds, amphibians, mammals and reptiles — about half of all known vertebrate species — and found that 8,851 (about 32 percent) have seen declining populations and shrinking areas of habitat. A more detailed analysis on 177 mammal species found that more than 40 percent have experienced significant drops in population. The findings, the study says, mean that billions of animal populations that once roamed the Earth are now gone.
[Earth is on brink of a sixth mass extinction, scientists say, and it’s humans’ fault].

Technology can be wonderful. But how do you keep track of yourself when technology allows you to be everywhere at once?
In this film Prof. Yair Amichai-Hamburger (director of the Research Center for Internet Psychology at the Sammy Ofer School of Communications) argues that even though technology allows us to reach out and connect more easily than ever before, if we don’t ever take a step back, we can lose track of our humanity in the process.
Roadmap to human cortex scale neuromorphic hardware
It should be possible to build a silicon version of the human cerebral cortex with the transistor technology that was in production in 2013. The resulting machine would take up less than a cubic meter of space and consume less than 100 watts, not too far from the human brain. This article is summarizing the work of Jennifer Hasler and Bo Marr writing in Frontiers of Neuroscience – Finding a roadmap to achieve large neuromorphic hardware systems.
Computational power efficiency for biological systems is 8–9 orders of magnitude higher (better) than the power efficiency wall for digital computation. Analog techniques at a 10 nm node can potentially reach this same level of biological computational efficiency. Figure 1 show huge potential for neuromorphic systems, showing the community has a lot of room left for improvement, as well as potential directions on how to achieve these approaches with technology already being developed; new technologies only improve the probability of this potential being reached.
‘Biological Teleportation’ Edges Closer With Craig Venter’s Digital-to-Biological Converter
The year is 2030. In a high-security containment lab, scientists gathered around a towering machine, eagerly awaiting the first look at a newly discovered bacterium on Mars.
With a series of beeps, the machine—a digital-to-biological converter, or DBC—signaled that it had successfully received the bacterium’s digitized genomic file. Using a chemical cocktail comprised of the building blocks of DNA, it whirled into action, automatically reconstructing the alien organism’s genes letter-by-letter.
Within a day, scientists had an exact replica of the Martian bacterium.
New research suggests problematic memories could be deleted
June 22 (UPI) — In a series of experiments, neuroscientists were able to selectively delete different types of memories stored a single neuron belonging to a marine snail.
The feat, detailed in the journal Current Biology, suggests problematic memories — like those responsible for PSTD and anxiety — in the human brain could be excised without harming other memories.
When the brain stores a traumatic experience in its memory bank, the memory is actually stored in multiple forms. Each memory can include bits of incidental information from the experience. Years later, these incidental, or neutral, memories can trigger panic attacks and severe anxiety.
Are Artificial Wombs the Future of Birth?
In April, Scientists based in Philadelphia unveiled an artificial womb undergoing testing on fetal lambs. With a prediction from one of the researchers that the technology could be ready for human testing in three to five years, artificial wombs suddenly became the most unexpected rage of 2017. But what sort of artificial wombs might realistically be a part of healthcare in the near future?
In this video series, the Galactic Public Archives takes bite-sized looks at a variety of terms, technologies, and ideas that are likely to be prominent in the future. Terms are regularly changing and being redefined with the passing of time. With constant breakthroughs and the development of new technology and other resources, we seek to define what these things are and how they will impact our future.
CellAge Has Secured a Seed Fundraising Round
CellAge, the synthetic biology company are going from strength to strength thanks to the support of the community last year during their fundraiser at Lifespan.io.
CellAge is featured in Startup Lithuania. As many of you will recall, CellAge hosted a successful project with us at Lifespan.io and they are busy developing a new aging biomarker for researchers thanks to the support of the community.
Now they are going from strength to strength having just secured a seed round backed by Michael Greve’s Kizoo Technology Capital and other investors.
Gigantic ‘alien megastructures’ built by an advanced civilisation could be orbiting dozens of nearby stars, boffin says
My theory, alien life will either be nearly impossible to find and we will spend centuries just looking for microbes. Or aliens will turn out to be so common that they could care less who we are and where we came from, and we will just be a new backwards species that turns up at the alien bar.
The world was electrified last year when it was suggested that scientists had spotted an “alien megastructure” orbiting a distant star.
Now a space boffin has suggested huge extraterrestrial constructions could be relatively easy to spot, so long as we look in the right place using the correct tools.
In 2016, one expert suggested the unexplained “winking” behaviour of a far-off sun called Tabby’s Star may have been caused by the rotation of a gigantic craft called a Dyson’s Sphere.
