So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists. Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size.

If those genes don’t work, babies are born with severely small brains, called microcephaly. Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency. In fact, the variations were so common they couldn’t be accidental mutations but instead were probably due to natural selection, where genetic changes that are favorable to a species quickly gain a foothold and begin to spread, the researchers report.

Lahn offers an analogy:

Twitter Facebook Research results show the eruption occurred in the 16th century BC, consistent with the archaeological record. The effects of the eruption were felt as far away as Egypt and what is now Istanbul in Turkey. Other researchers estimated the date of the eruption to about BC using measurements of radiocarbon, sometimes called carbon , from bits of trees, grains and legumes found just below the layer of volcanic ash. By using radiocarbon measurements from the annual rings of trees that lived at the time of the eruption, the UA-led team dates the eruption to someplace between and , a time period which overlaps with the date range from the archeological evidence.

Work conducted at the UA Accelerator Mass Spectrometry Laboratory contributed substantially to the radiocarbon calibration curve currently in use worldwide. Now radiocarbon testing requires just slivers of wood, so Pearson and her colleagues could test the annual growth rings of trees from back to BC — before, during and after the time Thera was thought to have erupted.

Pearson learned about the Thera eruption while studying archeology in college and has been fascinated by the eruption and its aftermath ever since. Narrowing the date for the Minoan-era eruption of the volcano Thera is so important for Mediterranean archeology that there have been whole conferences about when that eruption occurred, she said. Pearson wanted to know whether current dendrochronological and radiocarbon techniques could provide a more precise date for the eruption.

The radioactive carbon within an annual tree ring decays at a steady rate and can act as a clock indicating when the tree grew that ring. Pearson and her colleagues used two different tree-ring chronologies from long-lived trees that were alive at the time of the Thera eruption but were growing 7, miles apart. Brown provided 85 Irish oak annual tree-ring samples that spanned the same years. Because Irish oaks and bristlecone pines add a growth ring every year, the rings laid down year-by-year represent an environmental history going back thousands of years in time.

Social and dating Meeting people should be easy. After all, the world is full of them and they’re fairly evenly divided in terms of gender, height and so forth. They’re not perfect but they’re better than ordering brides by mail or submitting to your mother’s idea of who your perfect match is. Just like other means of meeting candidates for romance, dating sites are fraught with peril.

You could meet people you don’t like, people who don’t like you, people who are boring or even downright dangerous. But the same is true of just about any other method of meeting people. Ever ridden the subway? What it comes down to is that there are risks in everything so as long as you take the obvious precautions — don’t meet strangers in dark places, don’t send money to someone you’ve never met and don’t reveal all your personal information in a single gush — online dating is probably less dangerous than crossing a busy street or trying to clean out your gutters on a windy day.

One thing’s for sure — there’s no shortage of dating sites. No one really knows how many there are but the answer is somewhere in the thousands.

Kapteyn — was using crossdating to reconstruct the climates of the Netherlands and Germany. Douglass sought to better understand cycles of sunspot activity and reasoned that changes in solar activity would affect climate patterns on earth, which would subsequently be recorded by tree-ring growth patterns i.

Wood Diagram of secondary growth in a tree showing idealised vertical and horizontal sections. A new layer of wood is added in each growing season, thickening the stem, existing branches and roots, to form a growth ring. Horizontal cross sections cut through the trunk of a tree can reveal growth rings, also referred to as tree rings or annual rings.

Growth rings result from new growth in the vascular cambium , a layer of cells near the bark that botanists classify as a lateral meristem ; this growth in diameter is known as secondary growth.

The science that uses tree rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences. The beginning of earlywood formation and the end of the latewood formation form one annual ring, which usually extends around the entire circumference of the tree. A tree-ring chronology therefore represents departures of growth for any one year compared to average growth. For example, an index of 0.

Usually this process tries to remove the growth trends due to normal physiological aging processes and changes in the surrounding forest community. Principles of Dendrochronology Henri D.

Tree-Ring Dating Dendrochronology Dr. Ron Towner from the Laboratory of Tree-Ring Research at the University of Arizona explains the principles behind dendrochronology and why this dating method is valuable to archaeologists. Ron demonstrates how to accurately count tree-rings, and discusses the importance of patterns and master chronologies. Family trees, the tree of life, getting back to your roots…. But beyond the powerful imagery that trees give us to represent our history, what can trees actually tell us about the past?

Dendrochronology is the scientific method of tree-ring dating. Americans first developed it in the early 20th century and now “dendro” is a common method of chronology that is used by scientists all over the world. Dendrochronology has become a fundamental tool in science, for reinforcing and expanding on the timelines of historical and ecological events in the past.

Dendrochronology operates on the principle that in temperate climates, like the southwestern United States, trees grow one ring every year. In the springtime when moisture surges, the cells of a tree expand quickly. Over the course of the summer as the ground becomes more dry, the cells begin to shrink. This change in cell size is visible in tree-rings, or growth-rings.
