Cervical cancer could be eliminated in most countries by 2100 – research

Millions of cases could be prevented with high HPV vaccine and screening coverageCervical cancer could be effectively eliminated in most countries around the world by the end of the 21st century, according to research.The HPV (human papilloma virus) vaccine, which protects against the virus that causes most cases, has dramatically reduced incidences of cervical cancer wherever uptake has been high. There are hopes that the jab given to young girls, together with occasional HPV screening, could e...

What makes someone gay? Science is trying to get it straight.

Heterosexual people have been less interesting to scientists than gay people, in terms of where they come from, because, evolutionarily speaking, being gay doesn't lead to a higher "higher reproductive fitness" — meaning, it doesn't lead to more babies. Across cultures, gay boys tend to be more interested in spending time with their mothers. We still don't really know why gay people are attracted to each other.

Gene therapy could treat rare brain disorder in unborn babies

Doctors could use Crispr tool to inject benign virus into foetus’s brain to ‘switch on’ key genesScientists are developing a radical form of gene therapy that could cure a devastating medical disorder by mending mutations in the brains of foetuses in the womb.The treatment, which has never been attempted before, would involve doctors injecting the feotus’s brain with a harmless virus that infects the neurons and delivers a suite of molecules that correct the genetic faults.

Schizophrenia's surprising link to the gut

For decades, researchers have tried in vain to answer the question: What causes schizophrenia?At the same time, we've developed a growing understanding of how intimately linked the bacteria in our gut and our brains are.New research shows that schizophrenics have vastly different microbiomes, potentially uncovering a cause of — and maybe a future cure to — schizophrenia. None Researchers have tried to pin down what exactly has to happen for schizophrenia to rear its ugly head, but to little avai...

Female human body blocks weak sperm, scientists find

Reproductive tract’s shape lets only strong swimmers through to egg, research suggests For millions of sperm it is the end of the road. Scientists have found evidence that the female reproductive tract is shaped in such a way that stops poor swimmers from reaching their goal.Researchers used small-scale models and computer simulations to show that pinch points that behave like gates along the sperm’s arduous path from cervix to egg allow only the fastest ones through. Continue reading...

Becoming: A Short Timelapse Film Shows a Single Cell Morphing Into a Complete, Complex Living Organism

From Jan van IJken comes "Becoming," a short timelapse film that documents "the miraculous genesis of animal life." He writes: In great microscopic detail, we see the 'making of' an Alpine Newt in its transparant egg from the first cell division to hatching. A single cell is transformed into a complete, complex living organism with a beating heart and running bloodstream. The first stages of embryonic development are roughly the same for all animals, including humans. In the film, we can ob...

Ancient rock wiggles could be earliest trace of moving organism

How Fast Can You Travel Before It Kills You?

The human body can withstand a lot before giving up and dying: falls from second-story windows, years of fevered substance abuse, wolf attacks, etc. We have a pretty good idea of what it can’t tolerate, but some ways of dying instantly have received less attention than others, and speed is one of these. We’ve all seen…Read more...

Five smart things honeybees can do

These insects’ brains may be tiny, but they’re better with numbers than many human children and they are past masters at communicating life skillsLast week, Australian scientists announced that honeybees (Apis mellifera) can learn to add and subtract. Fourteen bees were put through 100 training exercises in a maze – and got the correct answer between 64% and 72% of the time. “It is not that every bee could do this [spontaneously], but we could teach them to do it,” said Dr Adrian Dyer, co-author...
