A team has developed a method for selectively manipulating genetically engineered cells with ultrasound.

People often associate Escherichia coli with contaminated food, but E. coli has long been a workhorse in biotechnology. Scientists have now demonstrated that the bacterium has further value as part of a system to detect heavy metal contamination in water.

Researchers have published a method for 3D-printing an ink that contains calcium carbonate-producing bacteria. The 3D-printed mineralized bio-composite is unprecedentedly strong, light, and environmentally friendly, with a range of applications from art to biomedicine.

It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years. And when susceptible deer are infected, they die within days. Now, scientists have found gene variants in deer associated with the animals' susceptibility to EHD.

Fungal pathogens that cause pine ghost canker are infecting conifer trees in urban forests of Southern California, scientists found.

Researchers have created and preliminarily tested what they believe may be one of the first models for predicting who has the highest probability of being resistant to COVID-19 in spite of exposure to SARS-CoV-2, the virus that causes it.

Scientists recently announced the invention of a nanowire 10,000 times thinner than a human hair that can be cheaply grown by common bacteria and tuned to 'smell' a vast array of chemical tracers -- including those given off by people afflicted with a wide range of medical conditions, such as asthma and kidney disease. Thousands of these specially tuned wires, each sniffing out a different chemical, can be layered onto tiny, wearable sensors, allowing healthcare providers an unprecedented tool for monitoring potential health complications. Since these wires are grown by bacteria, they are organic, biodegradable and far greener than any inorganic nanowire.

A new study shows that a 2018 California bill banning routine antibiotic use in livestock is linked with reduction in some antibiotic-resistant infections.

Researchers have added components of plant chloroplasts to bacteria. This feat, 50 years in the making, allows them to analyze the proteins in greater detail in order to improve Rubisco, and eventually photosynthesis.

An international research team demonstrates that the European spruce bark beetle (Ips typographus) uses volatile fungal metabolites of plant defense substances as important chemical signals in their attack on spruce trees. The researchers also show that the insects have olfactory sensory neurons specialized for detecting these volatile compounds. The fungal metabolites likely provide important clues to the beetles about the presence of beneficial fungi, the defense status of the trees, and the population density of their conspecifics. The study highlights the importance of chemical communication in maintaining symbiosis between bark beetles and their fungal partners.

In a bid to understand why mosquitoes may be more attracted to one human than another, researchers say they have mapped specialized receptors on the insects' nerve cells that are able to fine-tune their ability to detect particularly 'welcoming' odors in human skin.

Researchers have generated the first induced pluripotent stem cells (iPSCs) from bats, gaining valuable insights into the close relationship between bats and viruses.

A Danish creek has surprised researchers by containing previously unknown virus species.

Changing the structure of a dietary fiber commonly found in a range of food products has been found to promote healthy gut bacteria and reduce gas formation, a finding that could help people with intolerances to fiber and irritable bowel conditions.

Researchers have confirmed the first cases of canine distemper virus (CDV), which can cause fatal neurological disease, in tigers and leopards in Nepal.

In a potential game changer for the treatment of superbugs, a new class of antibiotics was developed that cured mice infected with bacteria deemed nearly 'untreatable' in humans -- and resistance to the drug was virtually undetectable.

A new study in humans and mice shows the antibodies generated by your first COVID vaccination or infection can actually 'hurt' subsequent booster shots. That's because these antibodies rapidly 'mop up' the booster from the body, before it has a chance to stimulate the cells from the immune system. The scientists plan new experiments to administer drugs that transiently block antibody activity at the time of boosting to allow the vaccine to be sensed better by immune cells.

'Forever chemicals' are everywhere -- water, soil, crops, animals, the blood of 97% of Americans -- researchers are trying to figure out how they got there. Their recent findings suggest that the microbes that help break down biodegradable materials and other waste are likely complicit in the release of the notorious per- and polyfluoroalkyl substances (PFAS) into the environment.

The microbes responsible for some infections can rapidly mutate into variants that evade detection and treatment. Now, a newly developed procedure could help researchers catch up to these sneaky pathogens.

The spread of antibiotic resistance, where infectious bacteria are able to defeat the drugs intended to kill them, may not be primarily driven by antibiotic consumption, according to a new study.
