From 1851 to 1858, Henry David Thoreau noted a number of natural occurrences in detail, including the first flowering dates for over 500 species of wildflowers in Concord. Additionally, Alfred Hosmer, a botanist in the same area
, had recorded the flowering dates
of over 600 species of wild plants in 1878 and from 1888 to 1902. With that data, Richard Primack
, a biology professor at Boston University, and fellow researcher Abraham Miller-Rushing
spent years aligning old plant names with current names to study the change flowering patterns
from the recorded past to present. Their phenological
study concluded that plants in Concord, on average, are now flowering 10 days earlier than they were in Thoreau's time
(full article for the journal BioScience). [more inside]

Monsanto Is Going Organic in a Quest for the Perfect Veggie
- "The lettuce, peppers, and broccoli—plus a melon and an onion, with a watermelon soon to follow—aren't genetically modified at all. Monsanto created all these veggies using good old-fashioned crossbreeding, the same technology that farmers have been using to optimize crops
for millennia. That doesn't mean they are low tech, exactly. Stark's division is drawing on Monsanto's accumulated scientific know-how to create vegetables that have all the advantages of genetically modified organisms without any of the Frankenfoods ick factor." [more inside]

Take a stroll through French artist Vincent Fournier‘s
] gallery of animal photographs, and you’re likely to come across some creatures you’ve never seen before. Like, for instance, a jellyfish that is capable of electronically transmitting data across the Abyssal depths of the ocean. Or, perhaps, a scorpion that can perform semi-automated surgery on humans.
“These creatures come from the future—an imagined future, based loosely on current research on synthetic biology and genetic engineering,” says Fournier, of his project Post-Natural History, a series of digitally-altered photos of animals that do not yet exist. “The idea is that these are living species, reprogrammed by mankind to better fit our environment as well as to adapt to new human desires.”

Bacteria have a Hobo Code.
Next month's Science News
carries a pretty interesting overview about the cutting edge of microbial science, including recent studies showing "in many mammals a microbial community ferments various sweats, oozes and excretions into distinctive scents that reveal age, health and much more to knowing noses in a select social circle
". That's right, microbes are posting status updates to each other through smells, sharing with other microbes what they've learned about host animals.

After a species goes extinct, in some cases its "ghost"
may linger in the ecosystem it leaves behind in the form of evolutionary anachronisms. [more inside]

"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia
was written by Pliny the Elder
between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian
, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum
, famously recounted by Pliny's eponymous nephew Pliny the Younger

For a long time, there have been newspaper stories and covers of magazines that talked about “The end of antibiotics, question mark?” Well, now I would say you can change the title to “The end of antibiotics, period.”

The Course of Their Lives.
While much in medicine has changed over the last century, the defining course of a first year medical student's education is still 'Gross Anatomy.' This is their hands-on tour of a donated cadaver -- an actual human body -- and is an experience which cannot be replicated by computer models. When Milwaukee Journal Sentinel reporter Mark Johnson came up with the idea of following a med school gross anatomy class for a feature story, his editor challenged him to make it different. So he chose to intertwine the students' stories with that of Geraldine 'Nana' Fotsch, a living future donor, as sort of a stand-in for the cadaver. (Via

In a nutshell
, this new study provides evidence that we need a certain amount of sleep every night, because the brain takes this time to rid itself of toxic metabolic byproducts, which would otherwise accumulate in the brain and impair brain function, destroy neurons — and potentially cause neurodegenerative disorders.
