Scientists Call for Investigation of Mysterious Cloud-like Collections in Cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More

A new way to diagnose malaria

Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More

"Immortal" Cells from Henrietta Lacks Lead to Updated Rules on Genomic Data Sharing

Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.

The change, which expands the remit of an earlier data-sharing policy, is ... Read More

Scientists develop ‘electronic nose’ for rapid detection of C-diff infection

A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More

Catching Up, Part I: Meeting with Former Research Students at ASM in Boston in May.

In this post, I meet up with six of my former undergraduate students at the General Meeting of the American Society of Microbiology in Boston last May. We had a great dinner where we could catch up on challenges and cheer each other on. I am very proud of the great students in this post, who a... Read More

TWiV 300: So happy together

Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent  speaks with Dickson, Alan, Rich, and Kathy about their careers in science.


Hosts:  Read More

TWiV 299: Rocky Mountain virology

Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.


Host: Vincent ... Read More

Synthesis produces new antibiotic

A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.

The laboratory recreation of a fungus-derived antibiotic, viridicatumtoxin B, may someday help bolster the fight against bacteria that evolve resistance to treatments in h... Read More

UTHealth researchers find up to 3,000 times the bacterial growth on hollow-head toothbrushes

Solid-head power toothbrushes retain less bacteria compared to hollow-head toothbrushes, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Dentistry.

The results of the study are published in the August issue of the Journal of Dental Hyg... Read More

Small Molecule Acts As On-Off Switch for Nature's Antibiotic Factory

Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.

Their hope now would be to see whether it is possible to manipulate this switch to make nature's anti... Read More

From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

Rabies is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. A new article sheds light on how the virus hijacks the transport system in ner...

Home is where the microbes are: Home Microbiome Project announces results of study on household microbes

A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria.

A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. The study was conducted by researchers from the U.S. Departm... Read More

Ebola genomes sequenced

Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.

Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More

Zombie bacteria are nothing to be afraid of

Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.

A cell is not a soap bubble that can simply pinch in two to reproduce. The ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental ... Read More

Malaria’s Clinical Symptoms Fade on Repeat Infections Due to Loss of Immune Cells

Children who repeatedly become infected with malaria often experience no clinical symptoms with these subsequent infections, and a team led by UC San Francisco researchers has discovered that this might be due at least in part to a depletion of specific types of immune cells.

Working in Ugand... Read More

Breakthrough antibacterial approach could resolve serious skin infections

Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria ac... Read More

Gut bacteria that protect against food allergies identified

Common gut bacteria prevent sensitization to allergens in a mouse model for peanut allergy, paving the way for probiotic therapies to treat food allergies.

The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. By inducing immun... Read More

Ebola Doctor Reveals How Infected Americans Were Cured

Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

Ebola Could Eventually Afflict Over 20,000, W.H.O. Says

As the tally of deaths from the worst known outbreak of the Ebola virus continued its seemingly inexorable rise, the World Health Organization said on Thursday that the epidemic was still accelerating and could afflict more than 20,000 people — almost seven times the current number of reported c...
