… along with new, unfamiliar — and often poorly understood — risks.

Technology and business risks morph with changes in technology and how it is delivered. While cloud services are often considered more dependable, businesses face new risks with SaaS and public cloud — risks that are unfamiliar or not completely understood. People’s eyes pop open and ears perk up when they witness prolonged outage events such as the current issue with Atlassian. Suddenly, SaaS dependencies and resilience issues become relevant, as a business can’t access its favorite SaaS tool. The unique risk of using SaaS is that you don’t have control over the application or the tool and cannot reimplement yourself. It is also important to understand the cascading risks, as some of the well-known SaaS services are hosted on a leading hyperscaler’s infrastructure. You need to analyze the business impact of SaaS and cloud services outages just like for any other technology in your portfolio.

Trust but verify vendor claims about service-level agreements supporting operations and resilience plans. To ensure that your SaaS providers deliver on their own promises:

The system developed in Milano is robust and it also has the potential to process information encoded in different coupled systems, including far and enormous galaxies. Thanks to these new results, it is now possible to simulate in the lab complex coupled systems, with order altered by stable defects, difficult to be reproduced otherwise since involving ginormous scale, like galaxies, or part of extreme hydrodynamic systems.

Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research group coordinated by Antonio Ambrosio at the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), in Milano (Italy). The results, published in the journal Nature Photonics, show the realization of 100 light vortices, coupled to form an ordered structure, a light crystal.

Mutual interaction of light and nanostructured materials is the focus of the research of Antonio Ambrosio, Principal Investigator of the research line Vectorial Nano-imaging at IIT in Milano and grantee of the ERC Consolidator project “METAmorphoses.”

Scientists at the US Department of Energy have created a low-cost molten salt battery that can store energy for months — potentially giving us a way to store and use energy from renewables year round.

The challenge: To stop climate change, we need to transition toward cleaner sources of energy.

Renewable energy (especially wind and solar) has become increasingly cheap to generate over the last couple decades, but storage is still an issue — we can burn as much coal or gas as we want, whenever we need it, but we can’t force the wind to blow.

Cognitive dissonance in the government’s decision to approve Bay-du-Nord while professing to fight fossil fuel emissions responsible for climate change.

The decision to approve Bay-du-Nord is based on the low emissions intensity of the oil that will be produced with no accounting for end-use.

There’s still a long way to go, but it’s an important milestone.

Ten years ago, solar and wind didn’t even make up 1% of our global energy mix. Now, in just a decade, they’ve reached 10%. It may not seem like much, but becoming such a significant part of the global energy mix in such a short time is remarkable — though there’s still a long way to go.

The past couple of years have been horrendous in more ways than one, but that doesn’t mean all is bad in the world. In fact, renewable energy continued its impressive growth, according to research from Ember, a climate and energy think tank.

This doesn’t mean you need to don an ushanka and start marching. You can start taking collective action by focusing on community groups and connecting with climate leaders. This will likely help you solve other issues, too, like waste disposal, recycling, and community clean-up projects in your locale.

Conclusion

Combating climate change requires all of us to reconsider our individual and collective climate responsibility. As an individual, you can do your part and let others know what you are doing. It has never been easier to connect with the world and share than it is today. You can join others in writing letters to the editor of your local newspaper, or your local and national government representatives. You can join groups like Citizens’ Climate Lobby and learn how to engage policy decision-makers. And in your daily routines, you can lead by example.

Flooding is common in informal settlements in Bwaise, a neighbourhood in the Ugandan capital Kampala. Bwaise’s residents are largely excluded from planning and local decision-making processes, and have poor housing and limited access to sanitation and other essential services.

The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.

Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.

The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.
