New Blood Group Discovered After a 50-Year Mystery

GBUnited Kingdom|

Researchers from the UK and Israel have identified a new human blood group system called the MAL blood group, a significant scientific achievement following a unique case from 1972. The mystery began when a pregnant woman's blood sample was found to lack a surface molecule present on all other known red blood cells at the time. This absence remained unexplained for nearly five decades.

The findings were published in September 2024, marking the culmination of nearly 20 years of research led by UK National Health Service hematologist Louise Tilley. The MAL blood group adds to the already extensive list of blood group systems recognized, which are crucial for safe blood transfusions. Mismatches can lead to severe reactions, making this discovery significant for patient care, especially for those with rare blood types.

The MAL group is characterized by the absence of the AnWj antigen, which is present in over 99.9 percent of the population. Tilley's research team identified a genetic mutation responsible for creating an AnWj-negative blood type in three patients, indicating that other factors may also suppress this antigen. The study provides a pathway for further testing, allowing potential identification of underlying health issues in those with the rare blood type.

This new blood group highlights the intricate variations in human blood and the importance of continued research to enhance blood transfusion safety and patient care.

Andrew Tate Faces New Allegations of Rape and Coercive Control

Controversial influencer Andrew Tate has been accused by four women of rape, coercive control, and assault. One alleged victim recounted a disturbing encounter in 2013, claiming he told her he was "debating whether to rape you or not," before proceeding with an assault, as reported by The Guardian. The victim, who was in a relationship with Tate at the time, stated the incident occurred after a training session for one of his kickboxing fights. Tate has categorically denied all allegations, calling them "a pack of lies" and "gross fabrications." His legal team argues that claims for personal injury are barred due to a three-year limitation period. Three of the women had previously reported their allegations to the Hertfordshire police in 2019, but no charges were filed by the Crown Prosecution Service. A preliminary hearing regarding the claims is scheduled for April 15. In addition to these allegations, Tate faces investigations related to human trafficking and money laundering in Romania, with both he and his brother currently reported to be in Dubai.

Rare Quadruple Supernova Predicted to Outshine the Moon in 23 Billion Years

Researchers at the University of Warwick have identified a pair of white dwarf stars destined to produce a spectacular quadruple supernova that will shine ten times brighter than the moon. This significant event is projected to occur in approximately 23 billion years, far beyond humanity's timeline, according to a study published in *Nature Astronomy* on April 4. The binary system, designated WDJ181058.67+311940.94, is located just 150 light-years from Earth and has a combined mass of about 1.56 times that of the sun. The white dwarfs currently orbit each other every 14 hours, but this period will diminish drastically, culminating in explosive annihilation as they advance to within 1/60th of the Earth-Sun distance. Lead author James Munday remarked on the excitement of discovering such a high-mass system, while co-author Ingrid Pelisoli emphasized the importance of finding progenitors for type 1a supernovas near Earth. The upcoming explosions will enable astronomers to measure cosmic distances and understand the universe's expansion better. Despite the eventual explosion's magnitude, Earth would likely be unscathed if the event occurred today, as our planet is expected to be long gone due to the sun’s eventual demise.

UK Watchdog Launches Investigation into Online Suicide Forum Linked to 97 Deaths

Britain's broadcasting regulator, Ofcom, has initiated an investigation into an online suicide forum suspected of being linked to nearly 100 deaths in the UK. According to the National Crime Agency (NCA), the forum is connected to 97 fatalities, with some sources, including the BBC, estimating that approximately 50 of these suicides can be directly tied to the site. Ofcom is examining whether the service provider failed to implement necessary safety measures to protect users from illegal content and activity. Although the specific website remains unnamed, it is reportedly hosted in the United States and serves tens of thousands of members, including minors. Users allegedly exchange methods and instructions related to suicide. This investigation is the first of its kind under the Online Safety Act of 2023, which mandates that service providers promptly remove illegal content once identified. If the provider does not comply with Ofcom's requests, the regulator may pursue court action to enforce content removal and potentially impose fines of up to £18 million or 10% of worldwide revenue. Mental health advocates emphasize the urgency of shutting down the site to prevent further tragedies.
