Individual Lichens Can Have Up to Three Fungi

Jan. 17, 2019 — Individual lichens may contain up to three different fungi, according to new research from an international team of researchers. This evidence provides new insight into another recent discovery that ... read more

Gut Bacteria Make Key Amino Acids Dispensable, Expanding Food Options for Invasive Flies

Jan. 16, 2019 — Fruit flies fed antibiotics to suppress their gut microbiome are forced to avoid the best food patches if they lack vital amino acids, according to a new ... read more

Researchers Create 'Shortcut' to Terpene Biosynthesis in E. Coli

Jan. 16, 2019 — Researchers have developed an artificial enzymatic pathway for synthesizing isoprenoids, or terpenes, in E.coli. This shorter, more efficient, cost-effective and customizable pathway transforms E. ... read more

Jan. 15, 2019 — The cyanobacteria blooms that plague western Lake Erie each summer are both an unsightly nuisance and a potential public health hazard, producing liver toxins that can be harmful to humans and their ... read more

Jan. 15, 2019 — Scientists have completed one of the largest bacterial comparative gene expression studies to date and taken another step forward in understanding the African Salmonella strain that is currently ... read more

Jan. 15, 2019 — Scientists have shown how the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host. Studying adaption to hypoxic or ... read more

Jan. 15, 2019 — Two new species of fungi have made an appearance in a rapidly melting glacier on Ellesmere Island in the Canadian Arctic, just west of ... read more

Marine Bacterium Sheds Light on Control of Toxic Metals

Jan. 14, 2019 — An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper. Although essential to life, metal ions can also ... read more

Jan. 14, 2019 — New research suggests that the gut microbiome may help prevent the development of cow's milk allergy. Scientists found that gut microbes from healthy human infant donors transplanted into mice ... read more

Herpes Viruses and Tumors Evolved to Learn How to Manipulate the Same Ancient RNA

Jan. 14, 2019 — Herpes viral infections use the ancient genetic material found in the human genome to proliferate, mimicking the same process tumors have been found to manipulate, Mount Sinai researchers have shown ... read more

Gene-Editing Tool CRISPR Repurposed to Develop Better Antibiotics

Jan. 11, 2019 — Scientists have repurposed the gene-editing tool CRISPR to study which genes are targeted by particular antibiotics, providing clues on how to improve existing antibiotics or develop new ... read more

Jan. 11, 2019 — Engineers have developed a microfluidic technique that can quickly process small samples of bacteria and gauge a specific property that's highly correlated with bacteria's ability to ... read more

Jan. 11, 2019 — Scientists have discovered an unusual new light sensor in green algae. The sensor triggers a reaction that is similar to one in the human ... read more

Experimental Antibody 'Cocktail' Protects Animals from Three Deadly Ebola Viruses

Jan. 10, 2019 — Scientists have developed a combination of monoclonal antibodies that protected animals from all three Ebola viruses that cause human disease. The antibody 'cocktail,' called MBP134, is the ... read more

Madariaga Virus Spreads to Haiti

Jan. 10, 2019 — Madariaga virus (MADV), or South American eastern equine encephalitis virus (EEEV), has -- until now -- been found primarily in animals of South and Central America, with the first human outbreak ... read more

Bacteria Help Discover Human Cancer-Causing Proteins

Jan. 10, 2019 — Researchers applied an unconventional approach that used bacteria to discover human proteins that can lead to DNA damage and promote ... read more

Viral Production Is Not Essential for Deaths Caused by Food-Borne Pathogen

Jan. 10, 2019 — The replication of a bacterial virus is not necessary to cause lethal disease in mice infected with a food-borne pathogen called Enterohemorrhagic Escherichia coli (EHEC), according to a new study. ... read more

Jan. 10, 2019 — Scientists have created an 'on' switch for CRISPR-Cas9 that allows it to be turned on in select cells only, specifically those that have a particular protein-cutting enzyme, or protease. ... read more

Jan. 10, 2019 — In a first for plant virology, a team from CIRAD recently used nanopore technology to sequence the entire genomes of two yam RNA viruses. This as yet little-used but promising molecular biology ... read more

Lung Neuropeptide Exacerbates Lethal Influenza Virus Infection

Jan. 10, 2019 — Researchers found that lung immune cells (phagocytes) produce increased levels of neuropeptide Y (NPY) when mice are infected with severe influenza virus. NPY and its receptor form the NPY-Y1R axis. ... read more
