A researcher who specialized in cells and microorganisms, Margulis was one of the most important biologists in the last half century—she literally helped to reorder the tree of life, convincing her colleagues that it did not consist of two kingdoms plants and animals , but five or even six plants, animals, fungi, protists, and two types of bacteria. She knew I was interested in ecology, and she liked to needle me. Hey, Charles, she would call out, are you still all worked up about protecting endangered species? Margulis was no apologist for unthinking destruction. More than 90 percent of the living matter on earth consists of microorganisms and viruses, she liked to point out. Heck, the number of bacterial cells in our body is ten times more than the number of human cells! Bacteria and protists can do things undreamed of by clumsy mammals like us:

Volcanic Threat Assessment help prioritize risk reduction efforts at U. October 24, Since , there have been eruptions and 52 episodes of notable volcanic unrest at 44 U. When erupting, all volcanoes pose a degree of risk to people and infrastructure. However, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location.
The assessment uses 24 factors to obtain a score and threat ranking. The findings are in the newly published Update to the U.

Farm-Out Arrangement A contractual agreement in which a mineral rights owner or lessee assigns a working interest to another party who will become responsible for specific exploration, development or production activities. Fault A fracture or fracture zone in rock along which movement has occurred. When movement occurs the vibrations that are produced are known as an earthquake. Fault-Block Mountain A linear mountain that is bounded on both sides by normal faults.
Fault Creep A very slow movement that occurs on faults in response to continuous tectonic deformation. The deformation might not be accompanied by earthquake activity. Faults that creep usually have fewer earthquakes than faults that move suddenly. The photo shows a curb and sidewalk which were becoming offset due to creep along the Hayward Fault in California. The curb was repaired in

We will focus on the heliocentric model and learn about how Earth fits into the Solar System, Galaxy and Universe. We will focus on different types of weather patterns and see why certain regions have different atmospheric conditions. Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns. We will focus on minerals and how they are the building blocks of rocks and we will show how we can no longer live without these resources.
We will place emphasis on the different types of volcanoes around the world and the potential hazards that they impose on mankind. We will also focus on earthquakes and how we use seismic waves to locate their epicenters.

Age is determined by: One tritium unit is equal to one molecule of 3H per molecules of 1H and has an activity of 0. The measured concentration of 3He must be corrected for these other sources. Other concerns are the fractionation of 3He if a gas phase is present and the fact that the solubility of He is temperature dependent. As the 4He atom is essentially an a-particle which has gained 2 electrons, this isotope may be considered a viable research tool wherever a-decay processes predominate, and where subsurface flow conditions are well-constrained.
Groundwater ages are determined using 4He by first determining the solid-to-liquid mass transfer rate in the laboratory or by calibration using groundwater age data obtained through other methods. The age of the groundwater samples are then determined by measuring total He and Ne to correct for atmospheric helium, and then computing the 4He radiogenic component.

How old is your water? But the truth is that water quality will deteriorate the longer water stands in storage facilities or distribution lines. The longer it takes to get to the faucet, the more likely there will be problems. Water age is highly system specific, and many utilities have never calculated the age of water in their systems. How does water age?

Tritium is still be used since it is produced in the atmosphere in small amounts and it can be measured by low-level counting or by the ingrowth of its decay product He I don’t know why the article states a large range for He I expect it is a mash-up of He-3 ingrowth from tritium decay and the subsurface production of He-4 from alpha decay of heavy radioactive elements an alpha particle is a He-4 nucleus.
Thus it can be used to estimate age of very old water.

This study began in November and will continue through August BEG will conduct a number of tasks to accomplish this objective. The ability of phosphate fertilizers to mobilize arsenic from arsenical pesticide applications will also be evaluated, when information on phosphate fertilizer application can be obtained. Relationships between arsenic concentrations and other ions, particularly uranium and oxyanions, will be evaluated using existing databases to determine geologic rather than anthropogenic sources of arsenic.
The impact of different redox conditions on the distribution of arsenic will also be examined. Limited additional groundwater sampling will be conducted where necessary and feasible. Materials will be developed for technology transfer for interested agency staff. BEG will conduct a number of tasks to accomplish the objective. Potential impacts of groundwater discharge on river segments identified as impaired in the Total Maximum Daily Load program will also be examined.
The status of knowledge on distribution of riparian vegetation will also be examined because riparian vegetation can markedly affect contamination of surface water from groundwater discharge. Hovorka , principal investigator; Adrien Lindley, and Mike Barrett In this multiyear study funded by Texas Commission on Environmental Quality, the current geomorphic method for assessment of sensitive features is quantitatively evaluated using hydrologic methods. Typical upland karst features in the Edwards aquifer recharge zone, specifically sinkholes, are studied to determine their connectedness to the subsurface.
Because sinkholes may allow water or contaminants to be transported rapidly to the subsurface via fractures or conduits, they have the potential to be sensitive features during development. Eight pairs of constant-head, single-ring infiltrometer experiments at sinkholes and control plots, as well as another excavated solution cavity, have been conducted at two sites located in the Edwards aquifer recharge zone in southern Travis and northern Hays Counties.

It is an opportunity for us to reflect on the language and ideas that represented each year. So, take a stroll down memory lane to remember all of our past Word of the Year selections. Change It wasn’t trendy , funny, nor was it coined on Twitter , but we thought change told a real story about how our users defined Unlike in , change was no longer a campaign slogan. But, the term still held a lot of weight.

Honey bees are crucial pollinators , and their rapidly diminishing population may have severe effects on human agriculture. If available in bulk quantities, the silk could be used to produce high-strength medical sutures and lightweight forms of body armor.
Among the systems described are a laser -based weapon designed to divert hostile aircraft, an underwater sonic weapon for incapacitating SCUBA divers and a heat-based weapon designed to compel crowds to disperse. Such ” chimeric ” hybrids could give valuable insights into the development of human embryos. In future, the development may permit the production of efficient nanometer-scale electronics.
The invention could permit the creation of a range of electronic-fabric devices, including clothing capable of measuring pollutants, T-shirts that display dynamic information, and carpets that sense how many people are crossing them. The new material could enable the development of “artificial trees” that lower atmospheric concentrations of CO2 in an effort to lessen the effects of climate change. Among the new products and technologies showcased are large-screen OLED televisions, quad-core tablet computers and consumer-ready 3D printers.

From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott ‘s own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago.
The possibility of life on Mars is a subject of significant interest to astrobiology due to its proximity and similarities to date, no proof has been found of past or present life on Mars. Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms.
A study of biology includes the study of the chemical basis of living organisms, DNA. Other related sciences include microbiology and organic chemistry. The word science comes from a Latin word scientica, which means knowledge, or information. Science is a process of systematically gathering detailed information and gaining exact knowledge. We do not know all the “life” information secrets but we are learning more every day. The three biological life cycle s, are; Zygotic meiosis, Sporic meiosis, and Gametic meiosis, Amoeba – one basic life form.
Amoebas and there are many different kinds feed by phagocytosis the engulfing and ingesting of foreign particles or waste matter by phagocytes –they flow around their prey usually a smaller cell and engulf it. Organism that eat other organisms are usually called “consumers”. The amoeba’s cell membrane then fuses with itself, trapping the prey in a “food vacuole” where it will be digested. In the first place, no slight inconvenience results from too great separation beween branches of study which serve for the perfection of one art.
