Now, his understanding is clearer. This simple story sweetly portrays a realistic, loving relationship. Listeners on laps or in group settings will eagerly volunteer examples of how long forever is and when they had to wait for desired things.
Commendably, the tale helps youngsters approach an abstract math concept—time—concretely and creatively. The watercolor-and-colored pencil illustrations are warm and expressive, depicting lush backgrounds.
Grandpa has stark white hair and white facial hair; Nana looks less stereotypical, with a blonde bob and red specs. The author provides a link to some luscious recipes. Start earning points for buying books!

Depending on how these three factors shake out, the world could be facing several years of a halting post-pandemic transition—one marked by continued viral evolution, localized outbreaks, and possibly multiple rounds of updated vaccinations.
In general, the partial protection effect is one of the reasons why the four known endemic human coronaviruses—the ones that cause a common cold—have such mild symptoms.
A study in BMC Infectious Diseases shows that on average, humans are first exposed to all four of these coronaviruses between the ages of three and five—part of the first wave of infections that young children experience. Past studies make clear that partial immunity can keep people from getting seriously ill, even as coronaviruses successfully enter their systems. Long-term, the same is likely to be true for the new coronavirus.
This transition from pandemic to minor ailment, however, depends on how the immune response to SARS-CoV-2 holds up over time. A study published in Science on January 6 tracked the immune response of COVID patients for five to eight months post-infection, and while individuals varied, about 95 percent of patients had measurable levels of immunity.
Based on the spread of its family tree, researchers estimated in that the endemic coronavirus OC43 entered humans sometime in the late 19th century, likely the early s. Though the carnage of past coronaviruses has faded over time, the road to a relatively painless coexistence between humans and SARS-CoV-2 will likely be bumpy.
In the medium-term future, the impact of the virus will depend largely on its evolution. The human immune system, while protecting many of us from serious illness, is also acting as an evolutionary crucible, putting pressure on the virus that selects for mutations that make it bind more effectively to human cells.
The coming months and years will reveal how well our immune systems can keep up with these changes. New SARS-CoV-2 variants also make widespread vaccination and other transmission-blocking measures, such as face masks and distancing, more crucial than ever.
The less the virus spreads, the fewer opportunities it has to evolve. Current vaccines should still work well enough against emerging variants , such as the B. Other labs have found that mutations in Y. V2, the variant first found in South Africa, are especially effective at helping the virus elude antibodies.
V2 variant, according to another preprint published on January Those 21 people had mild to moderate cases of COVID, however, so their antibody levels were lower to begin with, perhaps explaining why their blood did not neutralize the Y. V2 variant. So far, currently authorized vaccines—which spur the production of high levels of antibodies—seem to be effective against the most concerning variants.
The new variants bring other threats as well. Some, such as B. Veldhoen adds that new variants also may pose a greater risk of reinfection to recovered COVID patients. Researchers are closely monitoring the new variants. To her astonishment, Starfire finds herself in the middle of winter, and before her stands Titans Tower , decrepit and crumbling.
As she investigates the structure, she encounters Cyborg as its only occupant, who has also fallen into disrepair and is now hooked to a bulky power generator. He reveals to Starfire that she is now twenty years in the future; the Titans have disbanded following her disappearance and gone their own ways. Starfire assumes that this is due to Warp's tampering with the time continuum and decides to seek out the others in hopes of finding Warp, and forcing him to fix whatever damage he caused.
However, he points her in the direction of Beast Boy and Raven. He lost touch with Robin a long time ago. In the course of her search, she finds a bald Beast Boy carving out a miserable existence as a carnival curio, and learns Raven has gone insane from loneliness, thinking that all around her is just an illusion. As she tries to find Robin, Starfire encounters Warp again, who has also aged due to her theft of the lens, which is actually a vortex regulator, the heartpiece of his time-travelling technology.
He demands it back to enable himself to return into his own time, but not before Starfire demands that he restore her past.
Warp replies that he has done nothing to damage her own time, because history cannot be changed at all. He explains that he went back in time to steal the clock because history said it disappeared, and history says it disappeared, because he went back to steal it. The course of past, present, and future is inevitable. He takes back the vortex regulator, but before he can finish her off, he is attacked and forced to retreat.
Starfire's defender turns out to be Robin, but with a new superhero identity: Nightwing. In his new hideout, Nightwing re-encourages Starfire by the fact that the Titans have always prevailed even against the impossible before and may do so yet again.
