  • The fossils of the Jehol Biota are from the Early Cretaceous period, about 130 million years ago, and they comprise a wide variety of animals and plants. So far, about 60 species of plants, 1,000 species of invertebrates, and 140 species of vertebrates have been found in the Jehol Biota.
  • One of the most remarkable discoveries to arise from these fossils came in 2010, when Michael Benton of the University of Bristol found color-banding preserved in dinosaur fossils. These stripes of light and dark are similar to stripes in modern birds, and they provided further evidence that dinosaurs evolved into birds. Benton also found that these fossils had intact mealnosomes—organelles that make pigments. This discovery allowed paleontologists to tell the colors of dinosaurs' feathers for the first time.

  • The researchers suspect they've reached a region of the solar-interstellar boundary that nobody had predicted. In this area, the magnetic field lines of the Sun link up with those of the interstellar field. Scientists are calling this linkage a "highway" for particles to travel along. It lets solar wind particles escape more readily, causing the drop in their intensity. And it opens the door for low-energy cosmic rays to slip in to our Solar System, which is why Voyager 1 is seeing so many of them. According the researchers at the press conference that announced these results, most steady-state models of the Solar System failed to predict anything like this. A few models did have a feature like this, but it was only a transient one that appeared at certain times of the solar cycle.

Revisiting The Purpose Of The Copyright Monopoly: Science And The Useful Arts | Torrent... - 0 views

  • If there’s one thing that needs constant reminding, it’s the explicit purpose of the copyright monopoly. Its purpose is to promote the progress of human knowledge. Nothing less. Nothing more.
  • [Congress has the power] to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.
  • has the power, and not the obligation

  • two kinds of monopolies: copyright monopolies and patent monopolies, respectively. Science and the useful arts. The “science” part refers to the copyright monopoly, and the “useful arts” has nothing to do with creative works – it is “arts” in the same sense as “artisan”, that is, craftsmanship.
  • the purpose of the copyright monopoly isn’t to enable somebody to make money, and never was. Its sole purpose was and is to advance humanity as a whole. The monopoly begins and ends with the public interest; it does not exist for the benefit of the author and inventor.
  • The second thing we note is the “science” part. The US Constitution only gives Congress the right to protect works of knowledge – educational works, if you like – with a copyright monopoly. “Creative works” such as movies and music are nowhere to be found whatsoever in this empowerment of Congress to create temporary government-sanctioned monopolies.
  • Which brings us to the third notable item: “the exclusive right”. This is what we would refer to colloquially as a “monopoly”. The copyright industry has been tenacious in trying to portray the copyright monopoly as “property”, when in reality, the exclusive rights created are limitations of property rights (it prohibits me from storing the bitpatterns of my choosing on my own hardware). Further, it should be noted that this monopoly is not a guarantee to make money. It is a legal right to prevent others from attempting to do so. There’s a world of difference. You can have all the monopolies you like and still not make a cent.
  • The fourth notable item is the “for limited times”. This can be twisted and turned in many ways, obviously; it has been argued that “forever less a day” is still “limited” in the technical sense. But from my personal perspective – and I’ll have to argue, from the perspective of everybody reading this text – anything that extends past our time of death is not limited in time.

  • “If this pans out, it’s potentially the biggest news in the outer Solar System since the discovery of the Enceladus plume,” says Robert Pappalardo, a planetary scientist at the Jet Propulsion Laboratory in Pasadena, California, who was not involved in the research.
  • Roth’s team spotted the plumes when Europa was at its greatest distance from Jupiter. Changing stresses in the moon's crust, caused by tidal forces between the moon and planet, may explain why the researchers didn't see any plumes in the November observation when Europa and Jupiter were close. “Maybe Europa is just burping once in a while,” Pappalardo says.

Stepson of Stuxnet stalked Kaspersky for months, tapped Iran nuke talks | Ars Technica - 0 views

  • Since some time in the second half of 2014, a different state-sponsored group had been casing their corporate network using malware derived from Stuxnet, the highly sophisticated computer worm reportedly created by the US and Israel to sabotage Iran’s nuclear program.
  • the malware was more advanced than the malicious programs developed by the NSA-tied Equation Group that Kaspersky just exposed. More intriguing still, Kaspersky antivirus products showed the same malware has infected one or more venues that hosted recent diplomatic negotiations the US and five other countries have convened with Iran over its nuclear program.
  • We see this battle or arms race emerging and now it involves some kind of confrontation between the security industry and nation-state sponsored spies

  • Kaspersky officials first became suspicious their network might be infected in the weeks following February's Security Analyst Summit, where company researchers exposed a state-sponsored hacking operation that had ties to some of the developers of Stuxnet. Kaspersky dubbed the highly sophisticated group behind the 14-year campaign Equation Group. Now back in Moscow, a company engineer was testing a software prototype for detecting so-called advanced persistent threats (APTs), the type of well-organized and highly sophisticated attack campaigns launched by well-funded hacking groups. Strangely enough, the developer's computer itself was having unusual interactions with the Kaspersky network. The new APT technology under development, it seemed, was one of several things of interest to the Duqu attackers penetrating the Kaspersky fortress. "For the developer it was important to find out why" his PC was acting oddly, Kamluk said. "Of course, he did not consider that machine could be infected by real malware. We eventually found an alien module that should not be there that tried to mask behind legitimate looking modules from Microsoft. That was the point of discovery."
  • What they found was a vastly overhauled malware operation that made huge leaps in stealth, operational security, and software design. The Duqu actors also grew much more ambitious, infecting an estimated 100 or so targets, about twice as many as were hit by the 2011 version.
  • So the Duqu 2.0 attackers pulled an audacious feat that Kaspersky researchers had never seen before. Virtually all of the malware resided solely in the memory of the compromised computers or servers. When one of them was restarted, the infection would be purged, but as the rebooted machine reconnected to the network, it would be infected all over again by another compromised computer in the corporate network. The secret lynchpin making this untraceable reinfection scheme possible was the Windows vulnerability Microsoft patched only Tuesday, which has been designated

  • The authors of the article note several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago - the span of Earth history known as the Ediacaran Period.
  • The authors of the paper recognise two new species of mushroom-shaped animal: Dendrogramma enigmatica and Dendrogramma discoides.
  • The new organisms are multicellular but mostly non-symmetrical, with a dense layer of gelatinous material between the outer skin cell and inner stomach cell layers. The researchers did find some similarities to other animal groupings, such as the Cnidaria - the phylum that comprises corals and jellyfish - and the Ctenophora, which includes the marine organisms known as comb jellies. But the new organisms did not fulfil all the criteria required for inclusion in either of those categories.

  • One way to resolve the question surrounding Dendrogramma's affinities would be to examine its DNA, but new specimens will need to be found. The original samples were first preserved in formaldehyde and later transferred to 80% alcohol, a mode of treatment that prevents analysis of genetic material.
