Freaky Eight-Letter DNA Could Be the Stuff Aliens Are Made Of

Conventional DNA is comprised of the familiar A, C, G, and T base pairs, but a newly created genetic system is packed with eight, thus doubling the number of letters normally found in self-replicating molecules. Intriguingly, the new system, dubbed “hachimoji,” could resemble the building blocks of extraterrestrial…Read more...

Why the zebra got its stripes: to deter flies from landing on it

Pattern seems to confuse flies, researchers who dressed horses up as zebras findThe mystery of how the zebra got its stripes might have been solved: researchers say the pattern appears to confuse flies, discouraging them from touching down for a quick bite.The study, published in the journal Plos One, involved horses, zebras, and horses dressed as zebras. The team said the research not only supported previous work suggesting stripes might act as an insect deterrent, but helped unpick why, reveal...

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...

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.

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...

2-Billion-Year-Old Squiggles Could Be the Earliest Evidence of a Mobile Life Form

The reported discovery of 2.1-billion-year-old fossilized track marks etched in sedimentary rock is pushing back the earliest evidence of self-propelled movement by an organism on Earth by a whopping 1.5 billion years.Read more...

Ancient rock wiggles could be earliest trace of moving organism

Scientists say 2.1bn-year-old fossils may show evidence of self-propelled motionA collection of short wiggly structures discovered in ancient rocks could be the earliest fossilised traces of organisms able to move themselves, scientists say.If scientists are correct, the 2.1bn-year-old structures point to an earlier origin than generally thought for eukaryotes – cells with a membrane-bound nucleus and which make up plants, animals and fungi – previouslybelieved to have first emerged about 1.8bn ...

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...

Newly Discovered Spiked Dinosaurs From South America Look Like Creatures From 'No Man's Sky'

Paleontologists in Argentina have uncovered a dinosaur unlike anything ever seen before. Alive some 140 million years ago, these majestic herbivores featured long, forward-pointing spikes running along their necks and backs. These spikes may have served a defensive role, but their exact purpose now presents a…Read more...

Women’s brains are four years younger than men’s, study finds

Analysis of metabolic brain age may explain differences in cognitive decline rate Women’s brains are nearly four years younger than men’s, at least in how they burn fuel, according to scans performed by US researchers.Scientists found that healthy women have a “metabolic brain age” that is persistently younger than men’s of the same chronological age. The difference is apparent from early adulthood and remains into old age. Continue reading...

The long battle against infectious diseases | Letters

Readers respond to a recent article and letter published in the GuardianI would like to clarify that, contrary to your article (The microbes are fighting back, and if anyone thinks there is a simple solution, they are wrong, 25 January), a few decades ago precisely no one in drug discovery thought that the war against infectious diseases had been won. Sir Alexander Fleming, who first discovered antibiotics, warned of microbial resistance and it has been known about ever since.The reason drug com...

Extras for an Hour, Voyagers for a Lifetime: 'Live Long and Evolve'

None Those were the days. Father and son huddled around a glowing TV screen, eagerly awaiting the next Star Trek episode. It was our ritual. The two of us would gather at a set time, sprawling on a tattered sofa with an armful of snacks: pastries, popcorn, maybe even ice cream. For an hour our lives were suspended; we were no longer citizens of planet Earth—neither pubescent grade schooler nor certified civil engineer. For an hour, we were extras aboard Captain Jean-Luc Picard's USS Enterprise...
