Arctic “methane bomb” may not explode even after permafrost thaws, new study suggests
In the Arctic, the key variables of future climate change lie beneath the surface. Microbes in the soil layer just above the frozen permafrost metabolize carbon, turning it into carbon dioxide and methane, a much more potent greenhouse gas. As these soils warm, more carbon is released, potentially setting off a warming feedback loop also […]
Breakthrough in transmitting information through fiber-optic networks brings the dream of a quantum internet inching closer
Scientists have built a new type of molecular qubit that helps connect quantum computers through existing communication technologies, laying the foundation for a future quantum internet. The new qubits contain a rare earth element called erbium, which has optical and magnetic properties that allow quantum information to be transmitted using the same wavelengths as fiber […]
The world’s first global carbon tax was about to be introduced. President Trump dealt a “devastating blow” to the agreement.
With relatively little fanfare, the first-ever global carbon tax was scheduled to be formally adopted as an international agreement this year. The International Maritime Organization (IMO), the United Nations agency that oversees global shipping, had drafted a net-zero framework to shift the industry to cleaner fuels. This is an important step in the energy transition, […]
Free radicals are highly reactive molecules. Are free radicals always harmful or do they have any benefits?
Free radicals have a bad reputation. These highly reactive and unstable molecules are associated with cancer, aging, and degenerative diseases such as Alzheimer’s disease. However, the body constantly produces free radicals as an important part of life-sustaining processes such as respiration, cell signaling, and defense against disease. So are free radicals really that bad, or […]
Matrix Push C2 uses browser notifications for fileless, cross-platform phishing attacks
Malicious attackers are leveraging browser notifications as a vector for phishing attacks to distribute malicious links using a new command-and-control (C2) platform called Matrix Push C2. “This browser-native fileless framework leverages push notifications, fake alerts, and link redirects to targeted victims across operating systems,” Blackfog researcher Brenda Robb said in a report Thursday. In these […]
