Global warming causes frogs to disappear and decimated frog species may be just the first in a wave of climate-induced extinctions, according to a clue discovered in the early 1990s, when researchers noted that two species of Latin America's brightly colored harlequin frogs were last observed following a particular warm year in the tropics. The frog infections are most likely the first in a coming series of 'climate-induced' epidemics.

The article share the author's experience in visiting the White River National Wildlife Refuge near Saint Charles, Arkansas. According to the author, floodwaters of White River nourish a forest that shelter most of its original species, including bald eagles, river otters, black bears and bobcats. Annually, up to 350,000 ducks, mallards, gadwalls, teals and wigeons, winter in the area. It was learned that the White River refuge harbors more than 250 species of birds, including rare songbirds, herons, egrets, storks and kites. The author said that plants have developed special adaptations to deal with flooding. Animals have also evolved special adaptations that enable them to thrive in bottomlands.

The article talks about epigenome and their function; The National Institutes of Health Roadmap Epigenomics Consortium with Manolis Kellis, a computational biologist in February, 2015 published a comprehension of how the human epigenome works.

Presents ideas concerning the engineering of cells that hunt and kill cancer cells in the human body. Necessity for the understanding of the communication of cells, and how they kill themselves in apoptosis; Idea that genes are responsible for apoptosis; Work of Robert Horvitz; Excitement of drug companies over issue; Goal of isolating cancerous cells from healthy ones in apoptosis.

A diagram is presented which explains the formation of volcanic archipelago Canary Islands, a territory of Spain, west of Morocco, caused by volcanic eruptions.

The article discusses the prototype of an agile remotely operated underwater vehicle (ROV) that Malcolm Maclver, a professor of mechanical engineering and neurobiology at Northwestern University, is building in his laboratory. The model, called GhostBot, in the form of a dusky and carnivorous fish, the ghost knifefish, that moves through the water differently from most other fish and senses the world differently as well, has been turned into a swimming robot incorporated with electrosense.

The article focuses on the instinctive ability, an advantage characteristic of women which can communicate in nonverbal ways and generally articulate things. Doctor of Philosophy (Ph.D.) Gary Klein says that women's intuition is derived from observation and experience which are recorded by the unconscious mind and is believed to be more accurate than men. It adds that the intuitive mind automatically responds to circumstances even the conscious mind does not pay attention.

The article informs that a seasonal dead zone in the northern Gulf of Mexico developed occasionally in the 1800s, but it's become more intense in the last few decades as farmers cranked up fertilizer use. According to a new study of sediment samples from the Gulf, the results suggest that while low-oxygen waters happen naturally, modern farming practices have made the condition much more common. Coastal bottom waters in the northern Gulf of Mexico now become depleted of oxygen almost every summer.

The article informs that for just about every substance, there's a microbe that eats it. That's even true for man-made pollutants that didn't exist 60 years ago. In 1997, microbiologist Steve Zinder of Cornell University isolated the microbe from sewage sludge contaminated with the chemical tetrachloroethene. Since neither chemical existed in nature prior to World War II, Zinder, microbiologists Rekha Seshadri and John Heidelberg of The Institute of Genomic Research in Rockville, Maryland, and their colleagues wondered how the bug could have evolved such talents. They also realized that sequencing the microbe's genome could yield insights into the microbe's metabolism.

While investigating the effect of immune genes on longevity, molecular geneticist Ted Brummel and his colleagues found that middle-aged fruit flies turned up the expression of an antibacterial gene just as they began to die off more frequently. Suspecting that exposure to bacteria might shorten the flies' life span, the researchers wondered what would happen if they eliminated bacteria from inside and outside the fly. Bacteria extended life span only if the fruit flies were exposed within 4 days of hatching; in fact, removing bacteria with antibiotics made old fruit flies live 10% longer. And the genetic makeup of the flies also mattered, because lifelong antibiotic treatment caused one normally long-lived mutant line to die at the same age as normal flies given antibiotics.

Using powerful DNA-sequencing tools developed for the Human Genome Project, scientists have sequenced partial or total genomes of hundreds of previously unknown microbes. The new research underscores the tremendous diversity of microbes in the open ocean, and it could help uncover the key roles of microbes in controlling the global environment. Researchers have determined the species of such unculturable microbes by identifying characteristic genetic fingerprints, but these tell them little about the microbes.

The article focuses on a study in which researchers have found a new receptor on mice and rat tongues that detects fat and helps prepare the body to digest it. The results may help explain why some people crave fat more than others and could help researchers uncover new ways to fight obesity. The taste bud receptors send a signal when they sense fat. The researchers learned this by applying fatty acids to the tongues of mice that had their digestive tracts tied off to prevent ingestion. Normal mice, but not those lacking the CD36 receptors, immediately cranked up their production of bile, which breaks down fats, the researchers report in the November 2005 issue of the Journal of Clinical Investigation.

This article presents information on a study related to sperm whales that bear testimony to ocean pollution. Sperm whales across the Pacific, even in mid-ocean areas thought to be pristine, are accumulating human made chemicals called persistent organic pollutants (POPs). DDT was the most common pollutant, followed by polychlorinated biphenyls. The research vessel Odyssey collected the data during a 5-year investigation of pollution across the world's marine food webs. The 12-person crew surveyed sperm whales, which range the globe and eat fish and giant squid. These massive mammals accumulate POPs in their tissues, making them likely indicators of the health of the world's oceans.
