Sugar could help detect cancer
So maybe sugar isn’t all bad. Research at University College London has found that consuming sugar could help doctors detect cancer in a person’s body. The procedure –called glucose chemical exchange saturation transfer – tracks the sugar through a person’s body, where, during an MRI exam, it “lights up” areas where the cancer has invaded. This approach could provide a safer and simpler alternative to the standard radioactive techniques used today.
This tactic is based on the fact that tumors consume much more glucose than healthy tissue. After having a person consume glucose, MRI scans can be used to see where the sugar goes – which should lead the doctors to the cancer. The new GlucoCEST uses radio waves to magnetically “label” glucose in the body, which can then be found by using simple imaging techniques. Instead of eating the sugar, a patient would receive an injection.
The researchers claim that cancer can be detected using roughly half the sugar that you would find in a standard chocolate bar, which could make this a particularly cost-effective method for detecting cancer.

Rotten egg smell and colon cancer
Hydrogen sulfide, the foul-smelling gas produced by rotten eggs, may turn out to be a key element in treatment colon cancer. As eggs rot, they produce the gas, which also, it turns out, is important to colon cancer metabolism. According to research from the University of Texas Medical Branch at Galveston, colon cancer cells produce large amounts of hydrogen sulfide, which allows the cancer to grow and survive. Colon cancer “thrives” on the smelly substance, using it to make energy, divide and continue to invade their host, according to the research team.
In this study, the researchers observed mice which had had colon cancer cells implanted into them. After withholding hydrogen sulfide, the scientists saw that the tumors grew much more slowly. The cancer cells also decreased in angiogenesis, the process by which a tumor hijacks oxygen and nutrients from the host for its own use.
The researchers determined that blocking certain chemicals could curtail cancer cell growth, which could lead to new treatment options.

Inconsistent bedtimes could stunt brain growth
Keeping a consistent bedtime for children could be an important element in how their brains develop. According to research published in Epidemiology and Community Health, kids who had irregular bedtimes in their early years scored lower on math, reading and spatial awareness tests than children who followed a consistent nighttime schedule.
The research was part of the UK Millennium Cohort Study, which analyzed the bedtimes of nearly 11,000 seven-year-olds. The scientists gathered data on the children at the ages of three, five and then seven to find out how well they were doing with their learning and whether this might be related to their sleeping habits. They determined that erratic bedtimes were most common at the age of three, when around one in five of the children went to bed at varying times. By age seven, more than half of the children studied had a regular bedtimes between 7:30 and 8:30 p.m.
Overall, children who had never had regular bedtimes tended to fare worse than their peers on the tests and the impact was more obvious throughout early childhood in girls than in boys.
The researchers, from University College London, suspect that irregular bedtimes could disrupt the body’s natural circadian rhythms and that such disruptions can cause sleep deprivation, which could undermine the brain’s ability to acquire and retain information.
