hiv_transmission: HIV transmission network (1988-2001)
A set of networks of HIV transmissions between people through sexual, needle-sharing, or social connections, based on combining 8 datasets collected from 1988 to 2001. Metadata includes test results of several diseases, as well as demographic variables such as age, ethnicity, and gender. Networks come in two flavors: egodyads and altdyads. Egodyads are the network among study-participants and their direct partners. Altdyads are the…

Researchers from the University of Warwick in the U.K. found that the geostationary orbit
— a region of space at the altitude of 22,000 miles (36,000 kilometers)
— is full of dangerous, previously unseen bits of space junk that could destroy satellites.
The geostationary orbit is quite unique.
Satellites at this altitude circle Earth in sync with the planet's rotation, appearing permanently suspended above a fixed spot on the equator.
A single satellite in t…

Space junk debris cloud discovered in high-traffic orbit 'is a potential minefield' for the costliest satellites
"The debris in geosynchronous orbit is a potential minefield."

Nogle gange hader jeg at bo på bŸhlandet. Da jeg boede alene, var det ikke det store problem, for så fyrede jeg op for anlægget, og så kunne knallerter, save og bonderŸve forsvinde som dug for solen. Når man så bor sammen med en, der dels altid går rundt med stimuli i hovedtelefoner og bliver overvældet over musik med lyrik i længere tid, så er der pludselig ingen måde at stoppe det på udover at tage hovedtelefoner på, som så bliver lŸbende afbrudt af spŸrgsmål eller hund der kræver opmærkso…

Due to an ongoing commercial spacecraft attitude control issue, NASA and Katalyst Space announced Wednesday the LINK spacecraft will not capture or boost the #Swift satellite to a higher altitude to extend its science mission: https://www.nasa.gov/news-release/nasa-updates-next-steps-for-commercial-swift-boost-mission/ - however, LINK still will attempt to conduct rendezvous and proximity operations with Swift to demonstrate key capabilities for the future of space exploration.

Starlink has by far the most satellites in orbit,
densely packed within a narrow altitude range, mostly near 550 kilometres from Earth.
A recent analysis by renowned space debris researchers Hugh Lewis and Donald Kessler shows that
this dense bit of orbit is the only altitude below 800 kilometres that is above the collisional runaway threshold.
In other words, if there is a collision at 550 kilometres altitude, the debris would collide with other satellites, making m…

A new CRASH Clock measures the chance of satellite collisions, and it’s ticking down fast
How prepared are we for a solar storm, bad software update or cybersecurity event that could trigger widespread loss of satellite control?

Will the Alps remain Europe's inexhaustible water source ?
The Waterwise project is collecting an unprecedented amount of data from across the Alpine peaks
to better understand the vulnerability of headwater catchments
— the high-altitude streams that feed the continent's major rivers.

The Alps are drying out: EU-funded project assesses the future of Europe's "water tower"
Will the Alps remain Europe's inexhaustible water tower? The Waterwise project is collecting an unprecedented amount of data from across the Alpine peaks to better understand the vulnerability of headwater catchments — the high-altitude streams that feed the continent's major rivers. #SmartRegions
