Laurie Graham, a molecular biologist at Queen’s University in Ontario and lead author on the paper, knows she’s making a bold claim in arguing for the direct transfer of a gene from one fish to another. That kind of horizontal DNA movement once wasn’t imagined to happen in any animals, let alone vertebrates. Still, the more she and her colleagues study the smelt, the clearer the evidence becomes.

Nor are the smelt unique. Recent studies of a range of animals — other fish, reptiles, birds and mammals — point to a similar conclusion: The lateral inheritance of DNA, once thought to be exclusive to microbes, occurs on branches throughout the tree of life.

Sarah Schaack, an evolutionary genomicist at Reed College in Portland, Oregon, believes these cases of horizontal transfer still have “a pretty big wow factor” even among scientists, “because the conventional wisdom for so long was that it was less likely or impossible in eukaryotes.” But the smelt discovery and other recent examples all point to horizontal transfers playing an influential role in evolution.

Summary: The resting brain repeatedly and rapidly replays faster memories of what a person has recently learned and practiced. The more a person replays the memory during rest, the better they become during subsequent sessions where they practice their newly learned skill.

In a study of healthy volunteers, National Institutes of Health researchers have mapped out the brain activity that flows when we learn a new skill, such as playing a new song on the piano, and discovered why taking short breaks from practice is a key to learning.

An international team of scientists says it has sequenced and assembled the entirety of the human genome, including parts that were missed in the sequencing of the first human genome two decades ago.

The claim, if confirmed, surpasses the achievement laid out by leaders from the Human Genome Project and Celera Genomics on the White House lawn in 2000, when they announced the sequencing of the first draft human genome. That historic draft, and subsequent human DNA sequences, have all missed about 8% of the genome.

The sequencing of the new genome fills in these gaps using new technology. It has different limitations, however, including the type of cell line that the researchers used in order to speed up their effort.

Because it was, 62 years ago, the first fully reusable space vehicle, two stages, both reusable. The same concept of Virgin Galactic SpaceShipTwo.

The bike’s powertrain uses a fuel cell to turn gaseous hydrogen into electrical energy.

The engine setup holds its own, too. The Apex H2 will feature a hybrid powertrain that will convert gaseous hydrogen into electrical energy via a special fuel cell, reports New Atlas. Ninebot says the hydrogen-electric setup will be able to generate over 80 horsepower and rocket the bike from zero to 60 mph in less than four seconds. Considering that the original Segway—yes, the infamous two-wheel personal transporter favored by mall cops—topped out at 10 mph, that’s pretty impressive, even if it is slower than the Apex concept’s quoted top speed of 124 mph. Of course, there’s one key difference between the two bikes: The Apex H2 will be one of the rare concept vehicles you’ll be able to buy.
