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: Medieval monks would copy manuscripts and each copy would inevitably contain errors — accidental mutations.

Ice-sheet dynamics Sampling the surface of Taku Glacier in Alaska. There is increasingly dense firn between surface snow and blue glacier ice. An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. At Summit Camp in Greenland, the depth is 77 m and the ice is years old; at Dome C in Antarctica the depth is 95 m and the age years.
The bubbles disappear and the ice becomes more transparent. Ice is lost at the edges of the glacier to icebergs , or to summer melting, and the overall shape of the glacier does not change much with time. These can be located using maps of the flow lines. These include soot, ash, and other types of particle from forest fires and volcanoes ; isotopes such as beryllium created by cosmic rays ; micrometeorites ; and pollen.
It can be up to about 20 m thick, and though it has scientific value for example, it may contain subglacial microbial populations ,  it often does not retain stratigraphic information. In polar areas, the sun is visible day and night during the local summer and invisible all winter. It can make some snow sublimate , leaving the top inch or so less dense. When the sun approaches its lowest point in the sky, the temperature drops and hoar frost forms on the top layer.

Combination of OSL, radiocarbon and micromorphology to clarify deposition and activity sequences in arid sites. Abstract Archaeological surveys of the Negev Highlands show that the settlement history of this arid environment oscillated widely over time. This observation is almost entirely based on scant sherd assemblages from surveys, with only a few chronometric ages from one or two archaeological features at a given site. The reasons for the scarcity of chronometric ages include insufficient attention to radiocarbon dating in past research, low amounts of datable organic material for radiocarbon dating and issues related to low rate of site accumulation, and incomplete preservation of activity remains.
In order to overcome these problems, we present here the results of a detailed chronometric radiocarbon and optically stimulated luminescence OSL dating study exploring the development of Negev archaeological sites in the third millennium BCE. The study included micromorphological analyses to aid identification of sedimentological and post-depositional processes at the studied sites.

Everything Worth Knowing About Scientific Dating Methods This dating scene is dead. The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.

Methods fall into one of two categories: These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating.

By Vijayalaxmi Kinhal Ecologist Recycling is crucial and even the smallest step can have significant benefits for the environment. A better understanding of the advanatges of recycling can ensure that it becomes a natural and important part of your life. From that amount, the following occured: As more waste ends in landfills, the bigger the problem gets.
Products that are not biodegradable or are slow to decompose, like plastic, can remain in landfill sites for centuries, often emitting gases that could be harmful to the environment. The EPA fact sheet pg. Conserves Natural Resources Manufacturing of products requires virgin sources of both renewable wood, and non-renewable fossil fuels or metal ore. At their current rate of extraction and use, the world will eventually run out of these precious natural resources.
So it is vital to save them for future generations. When products manufactured from the natural resources like metals or plastic are discarded in landfills, they are lost to humanity forever. Natural Resource Savings Recycling ensures sustainable use of limited resources. Saves “17 trees, 7, gallons of water, gallons of oil, and 3 cubic yards of landfill space” Recycled plastic:
