At the ends of the Universe there are black holes billions of times the mass of our sun. These giant quasars feed on interstellar gas, swallowing large quantities of it non-stop - and that is how they can be detected: The light that is emitted by the gas as it is sucked in and crushed by the black hole's gravity travels for eons across the Universe until it reaches our telescopes.

Looking at the edges of the Universe is looking into the past. These far-off, ancient quasars appear to us in their "baby photos" taken less than a billion years after the Big Bang: monstrous infants in a young Universe.

Generex Biotechnology Corporation has announced publication of a follow-up study from a Phase I clinical trial of the immunotherapeutic agent AE37 in patients with prostate cancer. The study demonstrates an association between a specific immune response generated by AE37 and improved overall survival.  

A prior study showed that AE37-immunized patients had better overall and disease-free survival as a group than would be expected from their disease status and the current study shows that patients with the strongest immunological response did the best. In particular, both the presence of AE37-induced T cells in peripheral blood as well as a robust delayed type hypersensitivity (DTH) response elicited by AE37 correlated significantly with overall survival.

The U.S. Food and Drug Administration has approved INVOKAMET™, a fixed-dose therapy combining canagliflozin and metformin hydrochloride in a single tablet, for the treatment of adults with type 2 diabetes. INVOKAMET provides the clinical attributes of INVOKANA® (canagliflozin), the first sodium glucose co–transporter 2 (SGLT2) inhibitor available in the United States, together with metformin, which is commonly prescribed early in the treatment of type 2 diabetes. 

Formerly conjoined twins Carl and Clarence Aguirre celebrated the 10th anniversary of their separation today with the medical team that successfully separated and cared for them at The Children's Hospital at Montefiore (CHAM) - the first documented set of twins to undergo a successfully staged separation of craniopagus twins in the world.

One in two and a half million live births are craniopagus - twins joined at the head - and when Carl and Clarence arrived at Montefiore from the Philippines in September 2003, they were already dying from complications of their condition. Doctors believe that without the surgery, both boys would have died in 6-8 months. 

Effective new drugs and screening would make hepatitis C a rare disease by 2036, according to a new computer simulation conducted by The University of Texas MD Anderson Cancer Center and the University of Pittsburgh Graduate School of Public Health. 

Hepatitis C, a virus transmitted through the blood, is spread by sharing of needles, the use of contaminated medical equipment, and by tattoo and piercing equipment that has not been fully sterilized. Those at the highest risk for exposure are baby boomers – people born between 1946 and 1965. Widespread screening of the U.S. blood supply for hepatitis C began in 1992. A majority of people were infected through blood transfusions or organ transplants before 1992.

Money can't make you happy but perhaps math can predict how much less unhappy you will be than if you lived in poverty.

The happiness of over 18,000 people worldwide has been predicted by a mathematical equation, with results showing that moment-to-moment happiness reflects not just how well things are going, but whether things are going better than expected.
