Why does the cosmic microwave background have a strange patch that is much colder than expected? Syed Faisal ur Rahman looks at some possible explanations.
Photonics experts at Heriot-Watt university are hailing a breakthrough in laser research.
They have come up with a new and relatively inexpensive way of creating a laser supercontinuum.
They hope it could eventually have applications in bio-imaging and optical communications.

That’s no longer the case. Blue Canyon Technologies, AAC Clyde Space, GomSpace, NanoAvionics, Tyvak and several others are ready and willing to build cubesats en masse. So it came as a surprise to many cubesat manufacturers when Kepler Communications announced plans in January to manufacture its constellation of 140 Internet of Things satellites in-house.
Kepler is poised to become one of the world’s largest cubesat operators once its constellation is fully in orbit, a target set for the end of 2022. Only Planet currently operates a fleet that large.
Instead of formally soliciting bids from a wide range of cubesat builders, though, Toronto-based Kepler turned to the University of Toronto Institute for Aerospace Space Flight Laboratory (SFL) for help setting up its own manufacturing line. Kepler also received 1 million Canadian dollars ($760,000) from the Canadian Space Agency to mature its bus design and production techniques, leading some observers to conclude national pride could play a role. Through Kepler, Canada is establishing a robust cubesat manufacturing capability.

There’s been a lot of discussion in recent times around the need to get more women into AI and the primary focus of this discussion has been on developing AI systems that represent both men and women in order to reduce bias. The necessity of including women in the development of AI is universally accepted as being a positive step, and of course, it extends beyond gender to ethnicity and nationality as well if we are to truly create anything without bias.
However, there’s a narrow focus within this discussion on including women with technical skills and we need to look beyond this. There’s a whole host of skills required to develop AI systems, from designing the user interface, user experience, user testing, product development, and the system testing and training required to successfully launch an AI solution.
Monash University is claiming its lithium-sulfur battery is the world’s most efficient and capable of allowing an electric car to travel over 600 miles between charges.
Intel Israel announced that the project is the first of its kind which uses AI to create “female intelligence.” The experts who worked on the project, led by data scientist and researcher Shira Guskin, analyzed thousands of insights from “veteran career women.” Once the initial advice was submitted by many women across the Israeli work force, the researchers passed the data through three algorithm models: Topic Extraction, Grouping and Summarization. This led to an algorithm which “processed the tips pool and extracted the key tips and guidelines.”
The AI said that women should fully invest in their careers, be confident, network, love, and trust their guts.

A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
Nematic superconductivity with spontaneously broken rotation symmetry has recently been reported in doped topological insulators, M x Bi 2 Se 3 (M = Cu, Sr, Nb). Here we show that the electromagnetic (EM) response of these compounds provides a spectroscopy for bosonic excitations that reflect the pairing channel and the broken symmetries of the ground state. Using quasiclassical Keldysh theory, we find two characteristic bosonic modes in nematic superconductors: the nematicity mode and the chiral Higgs mode. The former corresponds to the vibrations of the nematic order parameter associated with broken crystal symmetry, while the latter represents the excitation of chiral Cooper pairs. The chiral Higgs mode softens at a critical doping, signaling a dynamical instability of the nematic state towards a new chiral ground state with broken time reversal and mirror symmetry. Evolution of the bosonic spectrum is directly captured by EM power absorption spectra. We also discuss contributions to the bosonic spectrum from subdominant pairing channels to the EM response.
