Soon, 1 out of every 15 points of light in the sky will be a satellite
I'm outside at my rural Saskatchewan farm, chatting with my neighbors who I've invited over to appreciate the night sky through my telescope. After exclamations and open-mouthed wonder over Saturn's rings, and light that has been traveling through sp.....»»
A nebula that extends its hand into space
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4......»»
"Lost" spy satellite orbited Earth undetected for 25 years—until now, scientists say
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post.....»»
Attackers may be using TunnelVision to snoop on users’ VPN traffic (CVE-2024-3661)
Researchers have brought to light a new attack method – dubbed TunnelVision and uniquely identified as CVE-2024-3661 – that can be used to intercept and snoop on VPN users’ traffic by attackers who are on the same local network. .....»»
Physicists reach atomic-scale telegraphy with light
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency.....»»

CJEU Gives File-Sharer Surveillance & Data Retention a Green Light
In a judgment published today, Europe's top court concludes that suspected file-sharers can be subjected to mass surveillance and retention of their data as long as certain standards are upheld. Digital rights groups hoped to end the French 'Hadopi'.....»»
Study sheds light on cancer cell "tug-of-war"
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is a.....»»
Study identifies early warning signals for the end of the African humid period
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the syste.....»»
