› Plant-eating lizards on the cusp of tooth evolution
Researchers found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional. |

› Scientists find evidence the early solar system harbored a gap between its inner and outer regions
In the early solar system, a 'protoplanetary disk' of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new study suggests that a mysterious gap existed within this disk around 4.567 billion years ago, and likely shaped the composition of the solar system's infant planets. |

› Plankton head polewards
Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many organisms to head to the poles and form new communities -- with unforeseeable consequences for marine food webs. |

› Ultrafast magnetism: heating magnets, freezing time
Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this principle. However, the microscopic mechanisms of ultrafast demagnetization remain unclear. Now, a team has developed a new method at BESSY II to quantify one of these mechanisms and applied it to the rare-earth element Gadolinium, whose magnetic properties are caused by electrons on both the 4f and the 5d shells. |

› Behavior resembling human ADHD seen in dogs
A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD). |

› Flu and heart disease: The surprising connection that should convince you to schedule your shot
Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiovascular risks. |

› Why do we remember stressful experiences better?
When the brain stores memories of objects, it creates a characteristic pattern of activity for each of them. Stress changes such memory traces. |

› Cellular environments shape molecular architecture
An important cellular structure called the nuclear pore complex (NPC) has larger dimensions than previously thought. A research team made this discovery using cryo-focused ion beam (cryo-FIB) milling and cryo-electron tomography (cryo-ET) -- which allowed them to analyze the NPC directly inside cells. |

› How to program DNA robots to poke and prod cell membranes
A discovery of how to build little blocks out of DNA and get them to stick to lipids has implications for biosensing and mRNA vaccines. |

› Discovery of new role for the brain?s immune cells could have Alzheimer's implications
The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain's small vessels. |

› Contraceptive pill can reduce type 2 diabetes risk in women with polycystic ovary syndrome
A study has revealed for the first time that the contraceptive pill can reduce the risk of type 2 diabetes by over a quarter in women with polycystic ovary syndrome (PCOS). The research findings also show that women with PCOS have twice the risk of developing type 2 diabetes or pre-diabetes (dysglycemia) -- highlighting the urgent need to find treatments to reduce this risk. |
