On June 8th, with a radio source beamed at the asteroid designated 2014 HQ124
(less formally, "the beast") while two other telescopes tracked that beam's reflections, NASA was able to gather high-quality images
of the object as it zipped by a mere 776,000 miles from Earth. (Some asteroids are closer
, and a vast number of them could soon be better known
, but none have allowed as good an opportunity for radar obvservation.) Astronomy Magazine's account
adds a bit more detail: To obtain the new views, researchers paired the 230-foot (70m) Deep Space Network antenna at Goldstone, California, with two other radio telescopes, one at a time. Using this technique, the Goldstone antenna beams a radar signal at an asteroid and the other antenna receives the reflections. The technique dramatically improves the amount of detail that can be seen in radar images.
To image 2014 HQ124, the researchers first paired the large Goldstone antenna with the 1,000-foot (305m) Arecibo radio telescope in Puerto Rico. They later paired the large Goldstone dish with a smaller companion, a 112-foot (34m) antenna, located about 20 miles (32km) away.
The first five images in the new sequence — the top row in the collage — represent the data collected by Arecibo and are 30 times brighter than what Goldstone can produce observing on its own.Read Replies (0)

According to an article at The Escapist, a group of hardware developers is working on a portable version
of the long-rumored SteamBox console
, dubbed the SteamBoy. (Video tease
.) This portable version wouldn't be as powerful as some other Steam-centric rigs, but a representative of this group says "it will be possible to play the majority of current games in Steam."While the exact hardware itself is still under wraps, the SteamBoy design should feature a Quad-Core CPU, 4GB RAM, a 32GB built-in memory card, and a 5" 16:9 touchscreen. ... The pictured SteamBoy looks like a combination of the Steam Controller and the PlayStation Vita, with two touchpads, 8 action buttons, 4 triggers, and two additional buttons to the rear. While that should certainly be as functional as a Steam Machine, we still aren't aware what the system specs will be.Read Replies (0)

An anonymous reader writes MIT researchers believe the solution to misuse and leakage of private data is more transparency and auditability, not adding new layers of security. Traditional approaches make it hard, if not impossible, to share data for useful purposes, such as in healthcare. Enter HTTPA, HTTP with accountability.
From the article: "With HTTPA, each item of private data would be assigned its own uniform resource identifier (URI), a component of the Semantic Web that, researchers say, would convert the Web from a collection of searchable text files into a giant database.
Every time the server transmitted a piece of sensitive data, it would also send a description of the restrictions on the data’s use. And it would also log the transaction, using the URI, in a network of encrypted servers."Read Replies (0)

writes Adding to the well-known fish-killing effects deforestation has in increasing turbidity and temperature in streams, a study published in Nature Communications, (abstract, PDF access), demonstrates deforestation causes a depletion of nutrients in associated lake aquatic ecosystems and, as a consequence, impacted fish stocks. Lead author Andrew Tanentzap is quoted as saying, 'We found fish that had almost 70% of their biomass made from carbon that came from trees and leaves instead of aquatic food chain sources.' This has troubling implications, as 'It's estimated that freshwater fishes make up more than 6% of the world's annual animal protein supplies for humans ...' Additionally, this may have significance in regard to anadromous species, such as salmon, which help power ocean ecosystems. The BBC offers more approachable coverage.Read Replies (0)
OpenXcom 1.0 Released

It's a small class of video games that still draw interest or inspire an active community 20 years after their first release — even if we're now 40 years into the era of commercial video games
. Games like Doom
, the several iterations of Civilization
, and the Mario Brothers
franchise will probably be around and played in some form many decades hence. The X-COM
family of games fits, too, having inspired various spiritual successors
since its release in 1994. Now, an anonymous reader writes that the open source (GPL) " OpenXcom 1.0 is finally released
, after 5224 commits, 1843 days, and 606 resolved issues since v0.9. 20 years of X-COM
oldschool lovers enjoy!"Read Replies (0)
