A new study in Nature Microbiology shows that the most common organism in the world’s oceans — and possibly the whole planet — harbors a virus in its DNA. This virus may have helped it survive and outcompete other organisms. The study began as a 91爆料 School of Oceanography senior thesis.
A team of chemical engineers has developed a new way to produce medicines and chemicals and preserve them using portable 鈥渂iofactories鈥� embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor鈥檚 offices or even basic refrigeration makes it hard to access critical medicines and other small-molecule compounds. The team 鈥� led by Hal Alper, a professor of chemical engineering at the University of Texas, and…
In oxygen-poor parts of the ocean, some microorganisms survive by breathing arsenic. This holdover from the ancient Earth was not thought to still exist in the open ocean.
In a comprehensive study of healthy corals published Nov. 22 in the journal Nature Communications, a team of scientists from the 91爆料 Bothell, Pennsylvania State University and Oregon State University report that coral bacteria are a surprisingly diverse bunch 鈥� and that different sections of the coral body can host unique communities of bacteria.
The bacterial communities that live inside each of our guts are relatively similar when times are good, but when stress enters the equation, those communities can react very differently from person to person.
A 91爆料 team has shed new light on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe’s entire genome, the oceanographers found that it significantly contributes to the removal of life-supporting nitrogen from the water in new and surprising ways.
91爆料 scientists have sequenced the complete genetic makeup of a species of ecologically important algae, which may aid in biofuel production.
A new book by 91爆料 geologist David Montgomery weaves history, science and personal challenges into an exploration of humanity’s tangled relationship with microbes, perhaps the least loved and most misunderstood creatures on Earth 鈥� and in you. “The Hidden Half of Nature: The Microbial Roots of Life and Health” comes out Nov. 16 from W.W. Norton & Co. Montgomery, a 91爆料 professor of Earth and space sciences, co-wrote the book with his wife, Anne Bikl茅, a biologist and…
The costly effects of cutbacks on maternal/child services, assuring a pure water supply, and what you need to know about Middle East respiratory syndrome.
People who are genetically equipped to stop hepatitis C viruses from turning off a type of interferon generally have a robust antiviral response. Findings on the mechanisms governing this ability suggest new avenues for treatment research.
Titanium-based materials can inhibit bacterial growth when bound to metal ions. If proven beneficial in clinical trials, certain titanates could be applied after a dental procedure to prevent infection or decay.
A new drug, called pritelivir, may offer a new treatment option for patients with genital herpes, a new industry-sponsored – study led by 91爆料 researchers has found.
When a bacterial cell divides into two daughter cells there can be an uneven distribution of cellular organelles. The resulting cells can behave differently from each other, giving them an evolutionary advantage.
Researchers hope to build a predictive model of the human microbiome to study what affects this massive biological system and to design ways to manipulate the microbiome to achieve desired clinical outcomes.
New research shows bacteria may draw other bacteria to an infection site by laying down trails of a 鈥渕olecular glue鈥� that attract free-swimming individual bacteria.
The Erasmus virus resets 207 genes in lung cells to hamper the cells’ ability to launch an antiviral reaction. Available drugs might correct this sabotage.
Latest research findings suggest the possibility of reverting TB hyper-susceptibility to TB hyper-resistance.
Bacteria speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Collisions can result in mutations.
Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. 91爆料 scientists consider the genetic underpinnings of such evolutionary rescue.
Microorganisms 鈥� 99 percent more kinds than had been reported in findings published just four months ago 鈥� are hitching rides in the upper troposphere from Asia.
