Blood’s Ancestral Blueprint: A 700-Million-Year Link to Single-Celled Ancestors

An international team led by Kyoto University traced the evolution of blood cells back about 700 million years, showing blood likely formed from ancient unicellular gene programs rather than arising anew with multicellular life. By comparing transcriptomes across species, they found macrophage-like ancestors and shared regulatory genes (notably Fos) that link early single-celled organisms to later mast cells, T cells, red blood cells, and platelets, revealing a deep evolutionary history with implications for understanding diseases such as cancer.

Five subtle signs of bowel cancer you should not ignore

A health feature outlines five early warning signs of bowel cancer—blood in the stool, persistent changes in bowel habits, abdominal pain, bloating, and unexplained weight loss—and urges anyone experiencing these symptoms to see a GP promptly. The piece highlights the value of early reporting for better outcomes and explains NHS screening options, including at-home FIT tests and follow-up tests like colonoscopy or CT scans if results are positive.

Blood Promised for Black Flag Resynced, Not a DLC Feature

Ubisoft's Assassin's Creed Black Flag Resynced remake faced questions after a reveal showing little gore. Ubisoft Singapore's Justin Ng assured on X that there will be blood in the final game (releasing July 9) and it won’t be a paid DLC, with gore and audio/visual effects being tuned in response to feedback. Fans also criticized parry sounds and VFX, but the team views the showcase as a chance to recalibrate before launch, and patches are expected after release following the game’s delay.

Scientists Reveal MAL Blood Group, Paving Precision Transfusions

A UK–Israel team identifies the MAL blood group system, linked to mutations in the MAL gene that remove the AnWj antigen; traced to a 1972 case and published in Blood (2024). This new blood type could improve matching for rare donors and enable tests to distinguish inherited versus antigen-suppression causes, potentially advancing transfusion medicine and patient care.

German police arrest man for blood-painted swastikas on vehicles and property

A man in Hanau, Germany, was detained for painting swastikas with his own blood on nearly 50 vehicles and buildings, with motives linked to personal and job-related issues. The incident, occurring in a city still haunted by a racist attack five years prior, has sparked shock and condemnation from local authorities, emphasizing that such symbols have no place in the community.

Blood Transformed into Bone-Healing Material for Personalized Implants

Researchers at the University of Nottingham have developed a 'biocooperative' material using blood and peptide molecules to enhance tissue regeneration, potentially leading to personalized, 3D-printed implants. This innovative approach leverages the natural healing processes of blood to create regenerative materials that can repair bones and other tissues. The method involves mixing synthetic peptides with a patient's blood to form a material that mimics and enhances the natural regenerative hematoma, offering a promising new avenue for regenerative medicine.

Microplastics in Blood Linked to Increased Heart Attack and Stroke Risk

A study published in Environmental International found microplastics in the blood of 18 out of 20 healthy participants, identifying 24 different polymer types. The research suggests that microplastics travel through the bloodstream and may pose risks to cardiovascular health, including vascular inflammation and changes in blood clotting. The study highlights the need for further research to understand the implications and potential health risks of microplastics in the human body.

"Deadly Discovery: Bacteria's Vampiric Attraction to Human Blood"

Scientists from Washington State University have discovered that certain disease-causing bacteria, including strains of Escherichia coli, are chemically attracted to human blood serum as a source of food, explaining their tendency to cause life-threatening sepsis. The research, published in the journal Elife, found that these bacteria are finely tuned to seek out blood for nourishment, a phenomenon the authors have termed "bacterial vampirism." The team hopes that understanding this behavior could lead to the development of new drugs to block this ability and prevent bloodstream infections, particularly in people with inflammatory bowel diseases.

"Bacterial Vampirism: Deadly Pathogens' Thirst for Human Blood"

Researchers at Washington State University have discovered a new trait called 'bacterial vampirism' among bacteria like Salmonella and E. coli, which are attracted to the liquid part of human blood, or serum, and can enter the bloodstream through small cuts in the digestive system, causing serious complications for people with inflammatory bowel disease. The bacteria can detect as little as a femtoliter of serum and swim toward it, a strategy called 'chemotaxis.' This new understanding could lead to the development of drugs to prevent sepsis in high-risk individuals.

"Identifying Blood-Based Targets for Treating Long COVID"

A study suggests that long COVID leads to ongoing inflammation in the blood, with distinct signs that could be targeted for treatment. The research, led by Imperial College London, found evidence of immune system activation in over 650 people who had been hospitalized with severe COVID-19, indicating potential targets for treatment using existing drugs that modulate the body's immune system. The study, published in the journal Nature Immunology, compared patients with long COVID to those who had fully recovered, revealing patterns of immune system activation and inflammation in those with prolonged symptoms.
