A new peer-to-peer botnet named Panchan appeared in the wild around March 2022, targeting Linux servers in the education sector to mine cryptocurrency.

Panchan is empowered with SSH worm functions like dictionary attacks and SSH key abuse to perform rapid lateral movement to available machines in the compromised network.

At the same time, it has powerful detection avoidance capabilities, such as using memory-mapped miners and dynamically detecting process monitoring to stop the mining module immediately.

Synthetic carbon allotropes are fascinating for their outstanding properties and potential applications. Scientists have devoted decades to synthesizing new types of carbon materials. However, a two-dimensional fullerene, which possesses a unique structure, has not been successfully synthesized until now.

A research group led by Prof. Zheng Jian from the Institute of Chemistry of the Chinese Academy of Sciences (ICCAS) developed a new interlayer bonding cleavage strategy to prepare a two-dimensional polymeric fullerene.

The researchers prepared magnesium intercalated C60 bulk crystals as the precursor to the exfoliation reaction. They then utilized a ligand-assisted cation exchange strategy to cleave the interlayer bonds into bulk crystals, which led to the bulk crystals being exfoliated into monolayer nanosheets.

Lasers produce coherent waves of light: All the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As a result, we can build “atom lasers” containing coherent waves of matter. But can we make these matter waves last, so that they may be used in applications? In research that was published in Nature this week, a team of Amsterdam physicists shows that the answer to this question is affirmative.

Getting bosons to march in sync

The concept that underlies the atom laser is the so-called Bose-Einstein Condensate, or BEC for short. Elementary particles in nature occur in two types: fermions and bosons. Fermions are particles like electrons and quarks—the building blocks of the matter that we are made of. Bosons are very different in nature: they are not hard like fermions, but soft: for example, they can move through one another without a problem. The best-known example of a boson is the photon, the smallest possible quantity of light. But matter particles can also combine to form bosons—in fact, entire can behave just like particles of light. What makes bosons so special is that they can all be in the exact same state at the exact same time, or phrased in more technical terms, they can “condense” into a coherent wave. When this type of condensation happens for matter particles, physicists call the resulting substance a Bose-Einstein Condensate.

NASA really doesn’t want SpaceX’s Starship to blow up on the launch pad at the agency’s Kennedy Space Center in Cape Canaveral, Reuters reports — a potential disaster so severe it could cut off the United States from accessing the International Space Station.

The facilities in question, Launch Complex 39A, served as NASA’s “Moonport” to deliver astronauts to the lunar surface during the Apollo program. Now, it’s the only launch pad capable of sending astronauts to the ISS — on board SpaceX’s much smaller Crew Dragon spacecraft — from US soil.

Now, SpaceX wants to pick up where NASA left off in the 1970s and return astronauts to the Moon in the upcoming years with its nearly 400-feet-tall Starship and Super Heavy booster stack. But the risk catastrophe, it terms out, is palpable.

Rabois’s pushback to remote work comes at a time when many workers are pushing to continue having the option, and companies who allowed it during the pandemic are deciding what their policies will look like moving forward. According to ADP Research Institute, 64% of workers surveyed said they would consider looking for another job if their employer asked them to return full-time.

While Protocol talked to other investors who argued that asking workers to return to the office shouldn’t be a big deal, not everyone agrees, and the debate has spilled over onto Twitter, giving the public a glimpse into how executives and investors view the issue.

In a response to Rabois’s tweet about only funding IRL startups, Jeremy Stoppelmann, cofounder and CEO of Yelp, tweeted that Rabois’s tweet was the “Equivalent to ‘looking to fund startups running Windows95.’”.

Check it out and post some of the stuff from it. My favorite because of fuel prices was this:

Many innovations in the mobility sector will be on the agenda, among them Japanese electric inflatable vehicles transportable in a backpack and operational in just a few seconds from Poimo, which will be seen for the first time outside Japan.

You will find many more innovations to investigate and post. Just google the companies listed in the link and their innovations.

VivaTech is the world’s rendezvous for startups and leaders to celebrate innovation. It’s a gathering of the world’s brightest minds, talents, and products.

Circa 2006 string theory would explain everything even extradimensional beings or even weird phenomenon. Basically it could even explain something even greater about our existence that even a God level entity had a grand design of our universe. It could even explain miracles by these entities using string theory. Even Einstein thought that there could be a great designer and oddly enough this could explain all things in physics and our world even an infinite multiverse that our universe is much more odd then we previously thought. String theory could even essentially be the next step after quantum mechanics.

In the first part of this paper, we explain what empirical evidence points to the need for having an effective grand unification-like symmetry possessing the symmetry SU-color in 4D. If one assumes the premises of a future predictive theory including gravity — be it string/M-theory or a reincarnation — this evidence then suggests that such a theory should lead to an effective grand unification-like symmetry as above in 4D, near the string-GUT-scale, rather than the standard model symmetry. Advantages of an effective supersymmetric G(224) = SU L × SU R × SU c or SO(10) symmetry in 4D in explaining (i) observed neutrino oscillations, (ii) baryogenesis via leptogenesis, and (iii) certain fermion mass-relations are noted. And certain distinguishing tests of a SUSY G(224) or SO(10)-framework involving CP and flavor violations (as in μ → eγ, τ → μγ, edm’s of the neutron and the electron) as well as proton decay are briefly mentioned.

Recalling some of the successes we have had in our understanding of nature so far, and the current difficulties of string/M-theory as regards the large multiplicity of string vacua, some comments are made on the traditional goal of understanding vis a vis the recently evolved view of landscape and anthropism.

Circa 2019

According to string theory, all particles and fundamental forces arise from the vibrational states of tiny strings. For mathematical consistency, these strings vibrate in 10-dimensional spacetime. And for consistency with our familiar everyday experience of the universe, with three spatial dimensions and the dimension of time, the additional six dimensions are “compactified” so as to be undetectable.

Different compactifications lead to different solutions. In string theory, a “solution” implies a vacuum of spacetime that is governed by Einstein’s theory of gravity coupled to a quantum field theory. Each solution describes a unique universe, with its own set of particles, fundamental forces and other such defining properties.

Some string theorists have focused their efforts on trying to find ways to connect string theory to properties of our known, observable universe—particularly the standard model of particle physics, which describes all known particles and all their mutual forces except gravity.

Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model. Instead, they could be upgraded with the latest sensors and processors that would snap onto a device’s internal chip—like LEGO bricks incorporated into an existing build. Such reconfigurable chipware could keep devices up to date while reducing our electronic waste.

Now MIT engineers have taken a step toward that modular vision with a LEGO-like design for a stackable, reconfigurable artificial intelligence .

The design comprises alternating layers of sensing and processing elements, along with light-emitting diodes (LED) that allow for the chip’s layers to communicate optically. Other modular chip designs employ conventional wiring to relay signals between layers. Such intricate connections are difficult if not impossible to sever and rewire, making such stackable designs not reconfigurable.
