UMass Amherst molecular biologist wins grant to outwit plant fungal diseases

(University of Massachusetts at Amherst) The Fusarium oxysporum fungus causes wilt in over 100 plant species including tomato, cotton, watermelon and banana, costing farmers billions of dollars in losses worldwide each year. The disease is difficult to control. Show More Summary

A genetic variation may increase tuberculosis susceptibility

(Mary Ann Liebert, Inc./Genetic Engineering News) -Researchers have shown that a single nucleotide change in a gene that affects production of hepcidin--a peptide involved in inflammation, immunity, and control of iron levels--is associated with greater susceptibility to extrapulmonary tuberculosis.

Shooting the achilles heel of nervous system cancers

(Dartmouth-Hitchcock Medical Center) A cooperative research team led by researchers at Dartmouth's Norris Cotton Cancer Center devised a strategy to target cancer cells while sparing normal cells by capitalizing on vulnerabilities that are exposed only in tumor cells. Show More Summary

Ancient Italian fossils reveal risk of parasitic infections due to climate change

(University of Missouri-Columbia) In 2014, a team of researchers led by a paleobiologist from the University of Missouri found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes.

Shale gas development spurring spread of invasive plants in Pa. forests

(Penn State) Vast swaths of Pennsylvania forests were clear-cut circa 1900 and regrowth has largely been from local native plant communities, but a team of researchers in Penn State's College of Agricultural Sciences has found that invasive, non-native plants are making significant inroads with unconventional natural gas development.

Reciprocal effects

(University of California - Santa Barbara) Postdoctoral research fellow Julia Buck discovers a new paradigm for describing trophic cascades caused by infectious agents.

Cow antibodies yield important clues for developing a broadly effective AIDS vaccine

(International AIDS Vaccine Initiative) As outlined in a study published today in Nature, lead author Devin Sok, Director, Antibody Discovery and Development at the International AIDS Vaccine Initiative (IAVI), reports the elicitation of powerful, HIV-blocking antibodies in cows in a matter of weeks - a process that usually takes years in humans.

Molting feathers may help birds deal with environmental contaminants

(Wiley) Mercury is a ubiquitous environmental contaminant that affects the health of birds and other wild animals.

Innate reaction of hematopoietic stem cells to severe infections

(University of Zurich) Researchers at the University of Zurich have shown for the first time that hematopoietic stem cells detect infectious agents themselves and begin to divide -- that is, without signals from growth factors. ThisShow More Summary

New mutations related to hereditary neuroendocrine tumours

(Centro Nacional de Investigaciones Oncológicas (CNIO)) The presence of a germline mutation in the GOT2 gene found in a patient with metastasis gives rise to increased activity of the encoder enzyme. Furthermore, the authors describe extraordinarily rare mutations in two patients: one in the SDHC gene and another in the IDH1. Show More Summary

Taste and health affect consumer choices for milk and nondairy beverages

(Elsevier) To learn more about what affects consumer decisions regarding fluid milk purchases, researchers from North Carolina State University used surveys, conjoint analysis, and means-end-chain analysis to uncover the underlying values among dairy milk and nondairy beverage consumers.

Mixed outcomes for plants and animals in warmer 2080s climate

(University of York) More than three quarters of plants and animals in England are likely to be significantly affected by climate change by the end of the century, say researchers.

The way rivers function reflects their ecological status and is rarely explored

(University of the Basque Country ) A study conducted by a UPV/EHU-University of the Basque Country research group within the framework of the European Globaqua project proposes going beyond the study of river ecosystems and incorporating...Show More Summary

Researchers improve method to identify aquatic species using environmental DNA

(University of Notre Dame) Researchers from the University of Notre Dame have improved their method of tracking species by using the biological material those organisms leave behind known as environmental DNA (eDNA).

In frogs, preventing early-life gut microbiome disruptions leads to better health

(University of Connecticut) Biologists at the University of Connecticut and University of South Florida have found that a crucial window in the development of tadpoles may influence a frog's ability to fight infectious diseases as an...Show More Summary

Loma Linda University researchers finds links between meal frequency and BMI

(Loma Linda University Adventist Health Sciences Center) A study by researchers from Loma Linda University School of Public Health and the Czech Republic has found that timing and frequency of meals play a role in predicting weight loss or gain.

Penn researchers engineer macrophages to engulf cancer cells in solid tumors

(University of Pennsylvania) In a recent study, human macrophages were engineered to ignore the 'don't eat me' signal both healthy and cancerous cells exhibit. Combined with cancer-specific targeting antibodies, these engineered macrophages invaded and engulfed human tumor cells in a mouse model.

A common underlying genetic basis for social behavior in dogs and humans

(Princeton University) In a new study published in the journal Science Advances, an interdisciplinary team of researchers, including those from Princeton University, identified genetic changes that are linked to dogs' human-directed social behaviors and suggest there is a common underlying genetic basis for hyper-social behavior in both dogs and humans.

Gu and Paranthaman named ORNL Corporate Fellows

(DOE/Oak Ridge National Laboratory) Researchers Baohua Gu and Parans Paranthaman have been named Corporate Fellows of the Department of Energy's Oak Ridge National Laboratory.

Damming and lost connectivity for fish in northeastern ecosystems

(American Institute of Biological Sciences) Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species.
