Like billions of supporting military units in addition to immune cells in the body, eukaryotic cells contained in all mammals also add to the body’s immune system via their own … Continue Reading Newly discovered cell defense soaks up toxins like a sponge.
Antibiotics are medicines used to prevent and treat bacterial infections. Antibiotic resistance occurs when bacteria adapt in response to the use of these medicines and become immune to their mode … Continue Reading Deadly superbugs killed by molecular drills.
A bacteriophage, also known as a phage, is a naturally-occurring virus with the awesome capability to infect and kill bacteria by injecting their DNA into bacterial cells which replicates until … Continue Reading Synthetic bacteriophages with programmable bacteria specificity engineered.
An artificial cell is a bioengineered particle mimicking a naturally occurring biological cell. The hypothesis involves synthetic entities biomimicking some of the properties of natural cells, such as surface characteristics, … Continue Reading New artificial cells successfully minimized to target and kill specific bacteria.
With the rapid advancement of robotic research, it has become increasingly important to develop biomimetic micro- or nanorobots capable of translating biological principles into robotic systems. Now, a study from … Continue Reading Biomimetic nanobots clear bacteria and toxins from blood.
Biofilms are where bacteria join together on a surface and start to form a protective matrix around their group, examples include dental plaque, a slimy biofilm of bacteria forming on … Continue Reading Magnetized bacteriophages successfully punch through biofilms to reach targets.
Bacteriophages are abundant in the environment, which means they are ecologically friendly. They infect and kill only bacteria, which means they could be used as novel biocontrol agents and even … Continue Reading Bacteriophage decontaminates infant formula infected with superbug.
Infectious diseases such as hepatitis C and some of the world’s deadliest superbugs, C. difficile and MRSA among them, could soon be detected much earlier by a unique diagnostic test, … Continue Reading Researchers develop world’s most sensitive universal diagnostic test for all disease.
At its annual assembly in Geneva last week, the World Health Organization approved a radical and far-reaching plan to slow the rapid, extensive spread of antibiotic resistance around the world. … Continue Reading New bacteriophage precision medicine reverses antibiotic resistance in bacteria.
Nanoengineers at the University of California, San Diego have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by … Continue Reading Study shows nanosponge cleans up MRSA infections without the use of antibiotics.
A new method of testing the most common cause of life-threatening infection in people with cystic fibrosis could improve efforts to study and combat the illness. The bacterium Pseudomonas aeruginosa … Continue Reading Researchers develop first human model of P. aeruginosa infection in cystic fibrosis lungs.
Antibiotic-resistant infections are on the rise, foiling efforts to reduce death rates in developing countries where uncontrolled use of antibiotics and poor sanitation run amok. The epidemic of ‘superbugs,’ bacteria … Continue Reading Bacteriophages encoded from antibiotic-resistant bacteria DNA, used to destroy parent bacteria.
One of the human body’s first responses to a viral infection is to make and release signalling proteins called interferons, which amplify the immune system response to viruses. Over time, … Continue Reading Ebola protein blocks early step in body’s counterattack on virus.
St. Jude Children’s Research Hospital scientists have discovered an enzyme that regulates production of the toxins that contribute to potentially life-threatening Staphylococcus aureus infections. The study is published in the … Continue Reading Discovery yields master regulator of toxin production in staph infections.
An experimental vaccine protected 100 percent of animal models against the highly infectious and virulent bacterium, Clostridium difficile, which causes an intestinal disease that kills approximately 30,000 Americans annually. The … Continue Reading C. difficile vaccine proves safe, 100 percent effective in animal models.
Saudi Arabian researchers have detected genetic fragments of Middle East Respiratory Syndrome coronavirus (MERS-CoV) in the air of a barn holding a camel infected with the virus. The study indicates … Continue Reading Researchers detect and confirm MERS-CoV genetic material in the air.
