10 more planets humans may be able to ruin — Researchers from NASA’s Kepler space telescope team announced we might get to bring our garbage party to another planet — OK, a bunch of them. The Kepler team has apparently identified 219 new planet candidates, 10 of which are roughly Earth-size and within their star’s habitable zone, the orbit zone around a star that could support liquid water and possibly life. This latest update to the Kepler catalogue brings the total number of planet candidates identified by the space-based telescope to 4034.
~ Well gosh, that’s heartening. Maybe they should have Keplered them to themselves?
Mystery Mars-sized planet — It’s been about 11 years since Pluto was demoted to dwarf planet status, leaving a 2370km-sized void in our hearts. Since then, the hunt for Planet X – aptly renamed Planet 9 – has grown into an international movement to find such an object in the Kuiper Belt beyond Neptune’s orbit. Now, scientists Kat Volk and Renu Malhotra from the University of Arizona’s Lunar and Planetary Laboratory are upping the ante: they suggest a completely different, tenth planetary-mass object is hiding somewhere in the Kuiper Belt as well.
~ Sigh. Or, you know, they’re just making suff up. It’s pretty dark out there.
Uranus is the loneliest thing in the solar system — It hasn’t had contact with anyone in over 30 years, since NASA’s Voyager 2 spacecraft whizzed by it on 24th January 1986. Thankfully, some good folks at NASA and elsewhere are advocating for missions to Uranus and its Ice Giant companion, Neptune, which could take place at some point in the next few decades.
~ If only I could think of a pun.
Satellites solve ‘bright nights’ — When Roman philosophers such as Pliny the Elder witnessed moonless nights glow bright like the day, it made an impression. Others since then have been awestruck by these ‘bright nights’ too.
Scientists from York University in Toronto have since observed what they call “enhanced airglow events” where elements in the night sky release photons. They know what’s causing airglow in their satellite data. But now they think they have figured out what enhances the glow, which may have caused the brighter nights documented throughout history.
~ Let me guess: was it light?
Study forces scientists to rethink human genome — As genetic sequencing has gotten cheaper and computerised data analysis has gotten better, more and more researchers have turned to what are known as genome-wide association studies in hopes of sussing out which individual genes are associated with particular disorders. If you have a whole lot of people with a disease, you should be able to tell what genetic traits those people have in common that might be responsible. This thinking has resulted in an entire catalogue of hundreds of research studies that has shed light on the genetic origins of diseases such as type 2 diabetes, Parkinson’s disease, Crohn’s disease and prostate cancer, while helping fuel the rise of personalised medicine.
But now, a group of Stanford University geneticists writing in the journal Cell posit that such large studies are actually likely to produce genetic variants with little bearing on the disease in question — essentially false positives that confuse the results.
~ ‘False positives’ really is cruel irony.
Stunning medieval longsword discovered in Polish bog — Late last month, an excavator operator was working at a peat bog in the Polish municipality of Mircze when he accidentally stumbled upon a glorious specimen of 14th century craftsmanship. The remarkably well-preserved longsword is a unique find for the area, and its discovery has prompted an archaeological expedition hoping to find more artefacts in the (location undisclosed) bog.
~ For the love of peat!
Study sheds new light on incredible 3000-year-old prosthetic toe — It’s called the Greville Chester Great Toe, and it’s one of the earliest prosthetic devices known to scientists. The Iron Age prosthetic was discovered by archaeologists 17 years ago in a plundered tomb that was carved into an older burial chamber known as Sheikh ´Abd el-Qurna, an acropolis just west of Luxor, Egypt. A team of researchers from the University of Basel and the University of Zurich are currently reexamining the device, and the archaeological site itself, using state-of-the-art techniques — and they’re learning some extraordinary new things about it.
~ Come on, if they could make a massive pyramid, a toe doesn’t seem that much of a stretch.
