Planet dwellers like us naturally look first to other moons and planets for colonization. Yet, asteroids have enough resources to build space habs for trillions, with the same living space per person as for Earth.

The idea is to use the materials from the asteroids and NEOs to make new habitats. This gives far more living space than the amount you get if you hollow asteroids out, and live inside them.

The Moon and Mars are our only choices for surface colonization in the near future. Neither is a second Earth; both have many issues at present, especially, the almost total lack of atmosphere. Technically, Mars does have an atmosphere, true, enough for winds and dust storms, but it is so thin it would count as a laboratory vacuum on Earth.

People often ask, "How close are we to sending humans to Mars" and it's not surprising given the optimistic presentations by Elon Musk and others. However, Mars is just too far away to send humans at this stage.

Dr. Jane Goodall is in a panic about GMOs and all of modern agriculture. What isn't plagiarized in her screeds about food is a mishmash of conjecture, anti-science mysticism, and lack of a clue about biology. She is not alone in losing her mind a bit with age. Dr. Linus Pauling became obsessed with Vitamin C as he aged, his claim that high doses would cure a cold is still promoted by supplement salespeople today. Dr.
What is a photon jet? Despite their exotic name, photon jets are a well studied thing nowadays. The original studies were performed by experimentalists who aimed to test quantum chromodynamics: they used to spend their time discriminating prompt photon production in hadron collisions from backgrounds. I remember a lot of such studies were performed in the 80ies and 90ies by my CDF colleagues, especially within the "QCD working group".
The importance of the detection of single, isolated photons of high energy has risen enormously since then, given their role in the discovery of the Higgs boson. Photon jets are in fact the background to beat down if you want a neat peak of H --> γγ decays to pop out of a mass histogram constructed from events featuring two photon candidates.
A new photoelectrode can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods, another step on the road to turning solar power from an expensive subsidized sideshow into the default energy of the future.
The famous paradox 'which came first, the chicken or the egg?' was created by philosophers to discuss cause and effect. Since chickens lay eggs, and eggs produce get the idea.
Since yesterday, and for almost a week, the literature festival in Mantova hosts "ScienceGround", a quite innovative initiative at the boundary between a science fair, a workshop, a library, and a place to hang around together and exchange ideas and information. The location is the beautiful hall of the church of Santa Maria della Vittoria, where a modular and dynamically configurable space has been set up.

Consider the statistical challenges around Dysonian SETI. The standard approach (for searches within the Milky Way) is to find stars that are "outliers", e.g. those that are significantly dimmer than their spectrophotometric characteristics and parallax would suggest. Statistical interpretation of the outliers of a single metric's distribution is not straightforward, however.

The normal/gaussian distribution is not normally found in nature. Real-world distributions are often skewed and long-tailed. Outliers (or "black swans") are to be expected.

A fully 3D printed array of light receptors on a hemispherical surface is the first significant step toward creating a "bionic eye."

The project began with a hemispherical glass dome to show how they could overcome the challenge of printing electronics on a curved surface. Using a custom-built 3D printer, they started with a base ink of silver particles. The dispensed ink stayed in place and dried uniformly instead of running down the curved surface. The researchers then used semiconducting polymer materials to print photodiodes, which convert light into electricity. The entire process took about an hour.
Two teams have announced the fifth and most prominent way that the Higgs boson - "the God particle" as it was once called - decays into other particles called bottom quarks. This pathway is the last to be detected of the five main signature pathways that can identify the Higgs particle.

Quarks are tiny constituents of protons, which themselves are some of the building blocks of atoms. The bottom quark is one of the six types of quarks that make up the menagerie of particles in the "standard model" that explains matter and their interactions
