A Whole New Species Can Develop In Just Two Generations, New Research Indicates
An island of the Galapagos archipelago is home to a brand new species which provides direct evidence that a species can develop from two other species in as little as two generations. The Galapagos Islands in the Pacific Ocean is such a remote area that it is the ideal place to study evolution, biodiversity and natural selection. The current research was an analysis of decades of field work on Darwin’s finches, inhabitants of this remote ecosystem   Read More ...

Cetaceans’ Big Brains Are Linked to Their Rich Social Life
Killer whales have group-specific dialects, sperm whales babysit one another’s young and bottlenose dolphins cooperate with other species. These social skills are all closely linked with the aquatic mammals’ brain sizes, according to a recent study in Nature Ecology & Evolution. Scientists first proposed a relation between social living and brain expansion, or encephalization, nearly three decades ago, when they observed that primate species with larger brains typically lived in bigger groups   Read More ...

The Tiger Subspecies Revised, 2017
There are certain animal species where – for reasons related to the charisma of the animal concerned, and the distinct nature of its various populations – we tend to learn about the various subspecies. Giraffes are one good example. Another is the Tiger Panthera tigris. Most people interested in animals know that tigers vary enough across their extensive (historical) range that the naming of several different forms is warranted   Read More ...

The "Birds Are Not Dinosaurs" Movement
A huge quantity of evidence shows that birds are dinosaurs, and specifically a lineage of the coelurosaurian theropod group Maniraptora. Additional support for the coelurosaurian origin of birds arrives on a regular basis, since new Jurassic and Cretaceous fossil species that fit somewhere on the bird lineage are reported virtually every month. But… I can’t help but be interested in ‘non-standard’ or ‘alternative’ hypotheses on evolutionary history, and among the most interesting is the ‘Birds Are Not Dinosaurs’ (or BAND) movement   Read More ...

Online software spots genetic errors in cancer papers
Two scientists have rolled out a program that spots incorrect gene sequences reported in experiments — and have used it to identify flaws in more than 60 papers, almost all of them studies of cancer. Jennifer Byrne, a cancer researcher at the Kids Research Institute of the Children’s Hospital at Westmead in Sydney, Australia, and Cyril Labbé, a computer scientist at the University of Grenoble Alpes in Grenoble, France, made public an early version of the program, called Seek & Blastn, in October and now they want other researchers to test the program and help to improve it   Read More ...

Myeloid Zinc Finger 1 and GA Binding Protein Co-operate with Sox2 in Regulating the Expression of Yes-Associated Protein 1 in Cancer Cells
The transcription factor (TF) yes-associated protein 1 (YAP1) is a major effector of the tumor suppressive Hippo signaling pathway and is also necessary to maintain pluripotency in embryonic stem cells. Elevated levels of YAP1 expression antagonize the tumor suppressive effects of the Hippo pathway that normally represses YAP1 function. High YAP1 expression is observed in several types of human cancers and is particularly prominent in cancer stem cells (CSCs)   Read More ...

Even Unpalatable Foods Taste Good to the Brain
When we experience something painful, our brain produces natural painkillers that are chemically similar to potent drugs such as morphine. Now research suggests these endogenous opioids also play another role: helping regulate the body's energy balance.

Biology's Beloved Amphibian--the Axolotl--Is Racing Toward Extinction
When biologist Luis Zambrano began his career in the late 1990s, he pictured himself working miles from civilization, maybe discovering new species in some hidden corner of Mexico’s Yucatán Peninsula. Instead, in 2003, he found himself counting amphibians in the polluted, murky canals of Mexico City’s Xochimilco district. The job had its advantages: he was working minutes from his home and studying the axolotl (Ambystoma mexicanum), a national icon in Mexico and arguably the world’s most recognizable salamander   Read More ...

The Evolution of a Graphic: Beetle Resurrection
My initial assignment for illustrating Hannah Nordhaus’ December 2017 article about the endangered American Burying Beetle, Nicrophorus americanus, was to represent the beetle’s life cycle.

The more I learned about N. americanus, however, the more this approach seemed inadequate to showcase the beetle’s fascinating behaviors and striking appearance   Read More ...

State officials say a University of Maine student has discovered a new species of wasp. Hillary Morin Peterson discovered the species while doing work for her thesis. The Maine Department of Agriculture, Conservation and Forestry announced the discovery on Thursday. The Brunswick resident named the wasp Ormocerus dirigoius, in tribute to Maine’s motto, “Dirigo.” It means “I lead” in Latin. Peterson discovered the small, non-stinging species of wasp while doing research about the invasive winter moths that live in Maine   Read More ...

EIF5A2 Contributes to the Maintenance of CD133(+) Hepatocellular Carcinoma Cells via the c-Myc/microRNA-29b Axis
Cancer stem cells (CSCs)/cancer-initiating cells (CICs) are suggested responsible for driving cancer resistance to conventional therapies and for cancer recurrence and/or metastasis. CD133 is served as a key biomarker to identify and characterize this subpopulation of cells in hepatocellular carcinoma (HCC). Our previous study indicated that overexpression of eukaryotic initiation factor 5A2 (EIF5A2) promotes HCC cell metastasis and angiogenesis. In the present study, we demonstrated that EIF5A2 might play a crucial role in CSCs regulation and investigated its potential molecular mechanisms   Read More ...
