Eating the flu
Given the importance and wide distribution of Influenza A viruses, it is surprising how little is known about infections of wild mammals. A new study led by Alex D. Greenwood and Gábor Á. Czirják of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin sheds light on which species are commonly infected and why. (2019-03-06)

Good neighbors
In the animal kingdom, food access is among the biggest drivers of habitat preference. It influences, among other things, how animals interact, where they roam and the amount of energy they expend to maintain their access to food. But how do different members of ecologically similar species manage to live close to each other? (2019-01-22)

Not just images
Hebrew University scientists have successfully transformed an MRI from a diagnostic camera into a device that can record changes in the biological makeup of brain tissue. The development will help doctors understand whether a patient is merely aging or developing a neurodegenerative disease, such as Alzheimer's or Parkinson's. (2019-09-05)

DNA exchange among species is major contributor to diversity in Heliconius butterflies
Exchange of genetic material among species played a major role in the wide diversity of Heliconius butterflies, according to a new study, results of which inform a centuries-long debate about the value of hybridization to species evolution. (2019-10-31)

Metabolite that promotes cancer cell transformation and colorectal cancer spread identified
Osaka University researchers revealed that the metabolite D-2-hydroxyglurate (D-2HG) promotes epithelial-mesenchymal transition of colorectal cancer cells, leading them to develop features of lower adherence to neighboring cells, increased invasiveness, and greater likelihood of metastatic spread. The finding highlights the value of targeting D-2HG to establish new therapeutic approaches against colorectal cancer. (2016-12-01)

The heat is on
Climate change is reorganizing the life in our oceans in a big way: as waters warm, cold-loving species, from plankton to fish, leave the area and warm water species become more successful. So say an international group of scientists in the most comprehensive assessment of the effects of ocean warming on the distribution fish communities. (2019-11-25)

Oncotarget: Researchers identify a potential molecular trigger for invasiveness in prostate cancer cells
A small protein modification can trigger the aggressive migratory and invasive properties of prostate cancer cells, according to new research published on the cover of Oncotarget. The findings give greater insight into how cancers can move from one location in the body to another, and could help develop more effective therapies in the future. Editorial by Xin Ye and Robert A. Weinberg can be found online. (2017-11-20)

Even flies like a familiar song
The process that allows sounds experienced during infancy to shape language is poorly understood. Researchers at Nagoya University found that courtship behavior in Drosophila melanogaster can be shaped by earlier auditory experiences. Their findings allowed them to develop a novel and simple neurological model to study how experiences of sound can shape complex modes of communication in animals. (2018-03-20)

Mechanisms explaining positional diversity of the hindlimb in tetrapod evolution
Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Nagoya University researchers found in eight tetrapod species that the position of the sacral vertebrae and the hindlimbs is determined by the initiation timing of Gdf11 gene expression. This will contribute to a forthcoming model explaining the coupling of spine and hindlimb positioning - a major step in fully understanding tetrapod evolution. (2017-08-18)

How to be a winner in the game of evolution
A new study by University of Arizona biologists helps explain why different groups of animals differ dramatically in their number of species, and how this is related to differences in their body forms and ways of life. (2017-01-13)

Life in marine driftwood: The case of driftwood specialist talitrids
The rare and difficult-to-sample driftwood talitrids, also called driftwood hoppers, are reviewed by David Wildish in the open access journal Zoosystematics and Evolution. The scientist links these crustaceans' trend to small size (dwarfism) to the poor quality of driftwood as food, and/or the size of empty burrows they occupy. Behavioural experiments suggest that the smallest talitrids can occupy most available burrows, whereas the largest ones could complete their life cycle in 58% of them. (2017-12-20)

Enhanced MR-guided focused ultrasound guidelines demonstrate improved efficacy and durability
Data released today show that MR-guided focused ultrasound is a more effective option for a broader population of uterine fibroid sufferers. In a poster presented today at the American College of Obstetrics and Gynecology annual meeting in San Diego, Phyllis Gee, M.D., of the North Texas Uterine Fibroid Institute in Plano, Texas, showed that women undergoing MRgFUS experience rapid and sustained relief from their condition and have a reduced need for alternative, invasive treatments in the future. (2007-05-08)

In communicating wildlife conservation, focus on the right message

Decreased oxygen levels could present hidden threat to marine species
In research published in Nature Scientific Reports, scientists from the University of Plymouth have shown that creatures which develop in hypoxic (low oxygen) conditions in the marine environment could experience previously unseen hindered development, and become compromised as adults. (2018-03-14)

Monitor climate change, not predators, to protect lake diversity: Study
Climate change and other environmental factors are more threatening to fish diversity than predators, according to new research from the University of Guelph. It is a surprising and important finding, as humans rely upon freshwater lakes for more than one-fifth of their protein needs worldwide, says lead author Prof. Andrew MacDougall in U of G's Department of Integrative Biology. (2018-03-23)

Bacteria might help other bacteria to tolerate antibiotics better
A new paper by the Dynamical Systems Biology lab at UPF shows that the response by bacteria to antibiotics may depend on other species of bacteria they live with, in such a way that some bacteria may make others more tolerant to antibiotics. (2020-03-12)

Animal images used in marketing may skew public perception about their survival risks
Many of the world's most charismatic animal species -- those that attract the largest interest and deepest empathy from the public -- are at high risk of extinction in part because many people believe their iconic stature guarantees their survival. (2018-04-12)

Targeted conservation could protect more of Earth's biodiversity
A new study finds that major gains in global biodiversity can be achieved if an additional 5 percent of land is set aside to protect key species. Scientists from Yale University and the University of Grenoble said such an effort could triple the protected range of those species and safeguard their functional diversity. The findings underscore the need to look beyond species numbers when developing conservation strategies, the researchers said. (2017-05-25)

Researchers describe first-ever hybrid bird species from the Amazon
A team of U of T Scarborough researchers have described the first known hybrid bird species to be found in the Amazon rainforest. Through a series of genetic and other tests the team have revealed that the golden-crowned manakin -- first discovered in Brazil in 1957 but not seen again until 2002 - is in fact a hybrid species. (2017-12-25)

Expanding tropical forest spells disaster for conservation
A North Carolina State University study shows that fire suppression efforts in Brazilian savannas turn many of those areas into forest lands, with negative consequences for the plants and animals that live there. (2017-08-30)

Fear of 'killer shrimps' could pose major threat to European rivers
The fear of invasive 'killer shrimps' can intimidate native organisms to such a degree that they are incapable of performing their vital role in river systems, a new study suggests. (2019-06-04)

How do people choose what plants to use?
There are about 400,000 species of plants in the world. Humans use approximately 10-15 percent of them to cover our basic needs, such as food, medicine and shelter, as well as other needs, such as recreation, art, and craft. But why and how have humans selected only a small fraction of all plants to utilize? (2017-01-23)
