hh, or the Bombay blood group, is a rare blood type. This blood phenotype was first discovered in Bombay by Y. M. Bhende in 1952. It is mostly found in the Indian subcontinent (India, Bangladesh, Pakistan and Iran).

people who have Bombay phenotype can donate red blood cells to any member of the ABO blood group system (unless some other blood factor gene, such as Rh, is incompatible), but they cannot receive blood from any member of the ABO blood group system (which always contains one or more of A, B or H antigens), but only from other people who have Bombay phenotype.

the usual tests for ABO blood group system would show them as group O.

Maybe not surprising in retrospect but blood typing is far more complex than I realized before going down the rabbit hole. The general article on blood types is also quite interesting. When you go beyond ABO and Rh typing there’s far more variety than what we typically think of for blood types.

As of June 2025, 48 blood-group systems have been identified by the International Society for Blood Transfusion in addition to the ABO and Rh systems.

The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 metres (980 ft) offshore in the north and 40 kilometres (25 mi) in the south within the country limits. The Belize Barrier Reef is a 300-kilometre (190 mi) long section of the 900-kilometre (560 mi) Mesoamerican Barrier Reef System, which is continuous from Cancún on the north-eastern tip of the Yucatán Peninsula through the Riviera Maya and down to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors. It is also vital to the country's fishing industry.

Repost, but an article came up about one in California .

I've seen a few rewilding campaigns in my community (Northeastern US) take shape over the last few years, and it makes me have a little hope. What with everything, all the time, I like when good news slips through.

Act Now to Stop War and End Racism (ANSWER), also known as International A.N.S.W.E.R. and the ANSWER Coalition, is a United States–based protest umbrella group consisting of many antiwar and civil rights organizations.

The Sega Channel was an online game service developed by Sega for the Sega Genesis video game console, serving as a content delivery system. Launched on December 14, 1994, the Sega Channel was provided to the public by TCI and Time Warner Cable through cable television services by way of coaxial cable.

By June 1994, 21 cable companies had signed up to carry the Sega Channel service. US fees varied depending on location, but were approximately $15 monthly, plus a $25 activation fee, which included the adapter. The Sega Channel expanded into Canada in late 1995, with an approximately $19 monthly fee.

The service would go on to garner as many as 250,000 subscribers; however, Sega had anticipated having over one million subscribers by the end of its first year, and had made the service available to over 20 million households.

In late November of 1997 it was announced that the Sega Channel would be shut down on June 30, 1998, but it ended up staying on for another month, finally being discontinued on July 31, 1998.

We had this when I was a kid. It came strangely late in the console's life, but it was cool. This was before cable modems were a household norm and it felt like the future in a way that console gaming didn't recapture for another couple generations. In retrospect that monthly fee was over $30 adjusted for inflation and it's wild that my parents were actually willing to pay that.

The medieval Palace Chapel (Hungarian: Várkápolna; formerly Alamizsnás Szent János-kápolna) in Buda Castle was built in the 15th century by King Sigismund as the lower chapel of the former Castle Church. The Gothic chapel, which survived the destruction of the 1686 siege, was buried under a Baroque terrace for centuries. After its reconstruction in 1963 became part of the exhibition of the Budapest History Museum.

Among all the niche, hyper-specific articles on Wikipedia, it's this one that surprises me that it exists.
