Circa 2016 This gives more exacting detail of the Tasmanian devils resistance to cancer.

A recently emerged infectious cancer has caused the near extinction of the Tasmanian devil, but some populations persist. Here, Epstein et al. provide evidence for possible resistance via rapid evolution in two genomic regions that contain cancer-related immune response genes.

Evolution has long been thought to be random, however, a recent study suggests differently.

Evolution has long been thought of as a relatively random process, with species’ features being formed by random mutations and environmental factors and thus largely unpredictable.

But an international team of scientists headed by researchers from Yale University and Columbia University discovered that a specific plant lineage independently developed three similar leaf types repeatedly in mountainous places scattered across the Neotropics.

By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.

O.o!!!!!

Changing the number of chromosomes an animal has can take millions of generations to happen in nature through the course of evolution – and now, scientists have been able to make these same changes in lab mice in a relative blink of an eye.

The new technique using stem cells and gene editing is a major accomplishment, and one that the team is hoping will reveal more about how the rearrangement of chromosomes can influence the way that animals evolve over time.

Analysis of the genome and proteome shows that eukaryotic evolution gave rise to the regulatory function of chromatin.

Two meters of DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

This finding “proved” the significance of chromosomal rearrangement, a crucial evolutionary indicator of the emergence of a new species.

Researchers from the Chinese Academy of Sciences (CAS) claim to have found a novel technique for programmable chromosome fusion successfully producing mice with genetic changes “that occur on a million-year evolutionary scale” in the laboratory.

The findings could shed light on how chromosome rearrangements—the tidy packages of organized genes provided in equal numbers by each parent, which align and trade or blend traits to produce offspring—influence evolution, reported Phys.org on Thursday.

Microsoft has shut down more than 1,400 malicious email accounts used by cybercriminals to collect stolen customer passwords via ransomware in the past year. The technology company has presented the second edition of ‘Cyber Signals’, a report that it produces periodically on cyber threats and that shows trends in security and cybercrime. In this issue, it offers insight into the evolution of extortion in cybercrime.

In this analysis, the company highlights that the specialization and consolidation of cybercrime have driven ransomware as a service (RaaS), which has become a dominant business model. RaaS programs, such as Conti or REvil, offer cybercriminals the opportunity to buy access to both ransomware payloads, leaked data and payment infrastructure.

Earth’s interior is a far from quiet place. Deep below our surface activities, the planet rumbles with activity, from plate tectonics to convection currents that circulate through the hot magmatic fluids far underneath the crust.

Now scientists studying satellite data of Earth have identified something inside Earth we’ve never seen before: a new type of magnetic wave that sweeps around the surface of our planet’s core, every seven years.

Montana this month gave a City of Billings contractor approval to build homes using 3D-printed walls for new construction in the state. The technology Tim Stark, the contractor, is using comes from Apis Cor, a Florida-based technology company that emphatically states on its website, “We print 3D buildings.”

The first time I encountered Apis Cor was when I wrote about the state of 3D-printed buildings back in 2016. Then Apis Cor was Russia-based and was working with a U.S. company. The website links in my posting back then for both the Russian and U.S. company no longer work. So I am guessing that the Apis Cor of today represents the evolution of both the technology platform as well as the business.

The current version of Apis Cor has constructed a number of pilot homes in the U.S. and the biggest 3D-printed building in the world in the United Arab Emirates. The technology has complied with some international building code standards but not yet in the U.S. Getting regulatory approval from the state of Montana, however, will likely open the door to seeing 3D printers being used more extensively here in North America, and can help lower the cost of home builds and solve growing demand.
