Ecology Highlight: PLOS ONE at ESA 2013


climate change vulnerable species


PLOS ONE is eagerly anticipating a trip to the 98th annual meeting of Ecological Society of America, August 4 – 10 in Minneapolis, to meet with our Academic Editors, authors, reviewers, and readers and to learn about the latest in ecology research. Attending the meeting will be Terry Monahan (Senior Editorial Manager), Lindsay Morton (Publications Manager), Elizabeth Silva (Associate Editor), and myself (Meg Byrne, Associate Editor).

In conjunction with the Ecology Society of America meeting, PLOS will be launching “The Ecological Impact of Climate Change Collection” on Monday, August 5, 2013. This collection, curated by PLOS ONE Academic Editor Ben Bond-Lamberty, highlights 16 articles recently published in PLOS ONE and PLOS Biology. These articles underscore the far-reaching impacts of climate change and the important contributions scientists are making to increase our understanding of how diverse species are effected by and are responding to climate change. Come back to the EveryONE blog on Monday for a full introduction to the collection by Dr. Bond-Lamberty.

“The Ecological Impact of Climate Change Collection” is part of a larger research and blog series at PLOS helping to refocus the conversation on climate change. The series is scheduled to run over a two-week period, between July 29 and August 9, and features pieces by 10 regular and guest bloggers, including award-winning science journalist Linda Marsa. Topics include changing habitats and species, climate modeling, the impact of climate change on disease, the difficulties facing science writers covering climate change, and the politics of climate change science.

Come find us at the meeting: We would love to hear about your research and your thoughts about the future of science publishing. We’ll be at booth #501 from Monday, August 5, 2013 through Thursday, August 8, 2013.

Resisting Antibiotics: Some Bacteria Get By With a Little Help From Their Friends


Antibiotic resistance is often in the news, as it threatens the effectiveness of one of the foundations of modern medicine. Usually, the concern is about resistance that is inherent to the bacteria, or else develops in bacteria through genetic changes. A paper published today in PLOS ONE suggests another possibility.

In “Chemical communication of antibiotic resistance by a highly resistant subpopulation of bacterial cells,” authors Omar El-Halfawy and Miguel Valvano reveal that some species of bacteria may help others in surviving an antibiotic attack. In addition, they were able to provide insight into the mechanics of how the bacteria perform this action.

The study began with an observation of the bacterial species Burkholderia cenopecia, which typically grows in the soil but can infect people who have cystic fibrosis and those with compromised immune systems. The authors noted that a subpopulation of the species was more resistant to the antibiotic polymyxin B than other bacteria of the species. In other words, these resistant bacteria were more likely to survive after treatment with polymyxin B, and levels of antibiotics that killed the less resistant bacteria did not harm this (more resistant) subpopulation.

When the authors grew the more-resistant B. cenopecia with another strain of bacteria called Pseudomonas aeruginosa (a disease-causing bacterium that can co-exist with B. cenopecia), the P. aeruginosa were much more resistant to the antibiotic than when they grew in isolation.

Why might the P. aeruginosa be more resistant when they were in the presence of B. cenopecia?

The authors suspected that the B. cenopecia were releasing something into their environment that interfered with the action of the antibiotic, making it less potent. Experiments revealed that the bacteria were indeed secreting two proteins associated with increased antibiotic resistance: putrescine (named for its putrid odor!) and Ycel, a protein whose function was previously unknown.

The large amounts of secreted putrescine blocked the antibiotics’ binding to the surface of the bacteria, and could make both B. cenopecia and P.aeruginosa more resistant to polymyxin B when grown together.

Ycel, on the other hand, was able to bind to the antibiotic directly, presumably decreasing its potency. Ycel is predicted to bind amphiphilic molecules (such as detergents, which  are attracted to both water and oil). Consistent with this prediction, the authors showed that Ycel had a protective effect against amphiphilic antibiotics and less of an effect against others.

These results have implications for combating the growing problem of antibiotic resistance. If we could prevent bacteria from making putrescine or Ycel, antibiotic treatments might be more effective, helping us eventually outflank resistance.

PLOS ONE Goes to the Mile-High City for ASM 2013

Bacillus anthracis - three color

PLOS ONE is looking forward to connecting with our editors, authors, reviewers, and readers at the 113th General Meeting of the American Society for Microbiology in Denver, Colorado. Representing PLOS ONE will be Damian Pattinson, Executive Editor; Lindsay Kelley, Editorial Board Manager; Camron Assadi, Product Marketing Manager; and myself (Meg Byrne, Associate Editor).

PLOS ONE continues to publish many high-profile papers in microbiology. Some of the most highly cited articles published since 2011 include a genomic characterization of a deadly Escherichia coli strain; a “field guide” to more than 3000 isolates of methicillin-resistant Staphylococcus aureus found around the world; the genome sequence of a novel ammonia-oxidizing archaeon (a member of the recently discovered third domain of life); and an analysis of the lung microbiomes in smokers with chronic obstructive pulmonary disease, smokers without COPD, and non-smokers.

In the last month, a number of publications have caught our readers’ eyes.  These include an article showing that a breast-milk protein can help fight antibiotic-resistant bacteria; a report of a new antibiotic developed from a bacteria-killing virus; a super-phylogeny of the over 3000 bacterial and archaeal genomes that have been sequenced to date; and an analysis of the immune response to a bacterial lung infection in a 500-year-old mummy.

Come find us at the meeting: We’d love to hear your thoughts about PLOS and science publishing, in general. We’ll be at booth #350 from Sunday, May 19th through Tuesday, May 21st.

For authors: Let us show you your article level metrics (ALMs) and give you a special author t-shirt.  We can also show off one of our latest features, Relative Metrics (Beta), which allows you to compare your paper’s usage to the average usage of articles in related subject areas.

For prospective authors: Please come ask us any questions you have about publishing in PLOS ONE and the family of PLOS journals. We can enumerate the many advantages of publishing in our open access journals, including free readership rights, reuse and remixing rights, unrestricted copyright, automatic posting of the article, and machine accessibility of the published article.

For PLOS ONE academic editors: We are looking forward to seeing you at our Editorial Board Reception on Monday May 20th from 5:30 to 7:30 PM at the Hyatt Regency.  We would love to fill you in on our plans for the future, get your feedback, and say a huge “Thank you!” It’s also a great opportunity to meet other academic editors. Please contact Lindsay Kelley or Camron Assadi for further information.

Also, PLOS Biology is looking forward to catching up with their academic editors at a “Meet the Editors” event on Sunday May 19th between 12:30 and 2:30 PM at the PLOS Booth.

We’re looking forward to seeing many microbiologists in Denver and discussing the small but mighty microbe.

How eels navigate to the Sargasso Sea

The migration of European eels (Anguilla anguilla) between freshwater habitats in Europe and North Africa and their spawning ground in the Sargasso Sea is one of the unsolved mysteries in animal navigation. Scientists have speculated that the eels may use the Earth’s magnetic field as a guide during their 6000 kilometer trip, and an article published today by Durif et al. strongly supports this idea.

To test the ability of eels to orient using a magnetic field, the authors used a carefully controlled laboratory setting, in which they eliminated other potential orientation cues, including odors, vibrations, light, and sounds.  They also created an artificial magnetic field, the same strength as the Earth’s magnetic field, which could be oriented in different directions.  Turning the artificial magnetic field between test runs helped rule out the possibility of the eels using other orientation cues.

The authors found that the eels consistently oriented in a particular direction with respect to magnetic north and that the eel’s particular orientation varied with water temperature.  Below 12 oC, which is the temperature range associated with eel migration, the eels oriented in the direction they had been transported from the holding tank to the testing tank.  This also corresponded with the direction of increasing water temperature.  Above 12 oC, the eels oriented at right angles to the direction they had been transported, which the authors speculate might reflect foraging behavior during times of the year the eels are not migrating.

Thus, eels seem capable of using the Earth’s magnetic field as a navigational guide.  They also seem to integrate this information with other cues, such as water temperature, to determine their direction of movement.

While these results provide some insight into how eels navigate to their spawning ground, other mysteries about eel migration remain, including where the spawning ground in the Sargasso Sea is precisely located.  For further reading about eel migration, see another paper published in PLOS ONE in October, in which Béguer-Pon et al. tagged adult American eels (Anguilla rostrata) to map their migration to the Sargasso Sea but instead learned something about porbeagle shark predation.

No sense of direction? Consider consulting some carp

The ability to navigate using the earth’s magnetic field is a skill that is not unique to humans.  Over the last few decades, scientists have discovered that numerous organisms have an ability to tell which way is north.  And the list is growing.

In one study, “Magnetic Alignment in Carps: Evidence from the Czech Christmas Fish Market,” Hart et al. reported that carp tend to align themselves along a north-south axis.  The authors photographed over 14,000 carp swimming in plastic tubs at pre-Christmas fish markets and found that, on average, the fish positioned themselves facing either the North Pole or the South Pole.

While the authors have not yet proven that carp can sense the geomagnetic field, they did rule out other possible orientation cues, including light, wind, temperature, and water flow. What benefit a common orientation may provide the fish remains unknown.  One possible explanation the authors present is that it may help the fish coordinate their movement when they swim in a school.

Some other organisms also have an ability to detect localized magnetic fields.  In a paper titled “Desert Ants Learn Vibration and Magnetic Landmarks,” Buehlmann et al. demonstrated that ants can sense a strong magnetic field created by two small magnets and use this as a landmark to find their nest.

In the absence of any other landmark (such as a vibrational, visual, or olfactory cue), ants who had been trained to associate the magnetic field with the nest entrance spent a lot more time near the magnetic field than ants who were naive to this landmark.  It is unclear how relevant this experiment is to ants in their natural environment, but the study nevertheless highlights the ants’ ability to sense a magnetic field.

While little is known about how carp align with the earth’s magnetic field or how ants sense a localized magnetic field, more is known about how some tiny organisms, aptly named magnetotactic bacteria, orient with a magnetic field.  These bacteria form straight chains of nano-size magnetic particles within the cells. The magnetic chains are attached to intracellular structures, thus allowing the bacteria to align passively with the earth’s magnetic field, like compass needles.

In a paper published earlier this month, Kalirai et al. showed that some magnetotactic bacteria form anomalous magnetic chains, with some sections of the chain oriented north and others south.  This finding contradicts scientists’ previous understanding that all the magnetic particles in a single chain would have the same alignment.  The study raises many questions: Would bacteria with anomalous magnetic chains have a competitive disadvantage in their natural environment?  Is there a single genetic mutation that leads to the anomalous magnetic chains?

All three of these studies raise intriguing questions, and we look forward to future discoveries from these scientists.

Great Genetics: PLOS ONE at ASHG

For the 2012 American Society for Human Genetics conference in San Francisco, we are highlighting a selection of recently published articles in the area.  In the last two years, PLOS ONE has published over 700 articles on human genetics; the eight summarized below are among the top 5% with regard to post-publication citations, HTML views, PDF downloads, and bookmarking.

Two of these papers address the genetic underpinnings of Alzheimer disease.  By mining genetic data, Jones et al. linked two physiological processes, cholesterol metabolism and the innate immune response, to late-onset Alzheimer disease development.  In a paper published in September of this year, Jun et al. discovered a correlation between the presence of cataracts and Alzheimer disease, and identified genetic variations in the gene encoding for the ?-catenin protein that may be the link between these two conditions.

Looking at another eye disorder, Nakano et al. investigated the genetic component of glaucoma.  Their research identified genetic variations among people of Japanese ancestry that are associated with certain types of glaucoma.

Another paper looked at the potential role of epigenetic modification in type 2 diabetes. Specifically, Bell et al. compared DNA from healthy women and women with type 2 diabetes and examined variations in DNA methylation, a chemical modification to the DNA that affects gene expression.  The analysis revealed significant methylation differences in regions of DNA previously associated with type 2 diabetes, suggesting that variations in DNA methylation may play a role in the disease.

Two studies considered variations in the number of repeats of specific DNA sequences, which can affect disease pathology and even drive evolution.  Valsesia et al. investigated DNA copy number variations and their effect on gene expression in seven different melanoma cell lines.  Their research identified candidate genes and molecular pathways involved in metastatic melanoma.  Zhang et al. compared the performance of four software programs in detecting copy number variations in DNA sequences longer than 1,000 bases.  The authors found inconsistency even among the most established programs, emphasizing the work that still needs to be done in this area.

Another paper addressed the issue of chromosome translocation, or the abnormal rearrangement of parts of chromosomes.  In a collaboration between biologists and physicists, Engreitz et al. showed that the three-dimensional organization of DNA in the cell nucleus may help explain certain chromosomal translocations linked to human disease.

Finally, using data from the Human Genome Diversity Project, Kirin et al. profiled the lengths and frequencies of DNA sequences that are identical on maternal and paternal chromosomes.  This large-scale analysis allowed the authors to make conclusions about historic and contemporary patterns of intra-communal parentage in different human populations.

If you are at the ASHG, we hope that you stop by the PLOS booth and meet some of the PLOS staff.  We will be at booth # 1606.  Also, if you have published in PLOS ONE, we have a stylish PLOS ONE author t-shirt to give you.  We look forward to seeing you there.

A selection of influential PLOS ONE papers on tropical medicine and malaria

For the XVIII International Congress for Tropical Medicine and Malaria Conference in Rio de Janeiro, PLOS ONE is highlighting eight recent articles.  Since January 2011, PLOS ONE has published almost 700 articles in the areas of tropical neglected diseases, tropical medicine, and malaria.  We’re sharing with you some of the papers that have received the most attention.  The authors on these papers come from across the globe, representing Brazil, Colombia, Ethiopia, France, the Netherlands, Papua New Guinea, Spain, Sri Lanka, Switzerland, the United Kingdom, and the United States.

One paper in particular has stood out.  Researchers found a novel therapy that could revolutionize the treatment of viral infections from the common cold to Ebola.  The therapy eliminates cells that contain viral RNA while leaving uninfected cells unharmed.  In the study, the therapy was effective against 15 different viruses, including dengue flavivirus, rhinoviruses, and H1N1 influenza virus.

An article published last month reported that malaria incidence in Sri Lanka has declined by 99.9% since 1999, despite ongoing conflict in the country.  The success of the malaria program could be explained in part by effective prevention measures, early detection, and maintaining the program in conflict zones.  In less than a month, the paper has received over 1,000 views.

Bacteria on people’s skin can affect how attractive they seem to malaria-transmitting mosquitoes.  Research published last December found that malaria mosquitoes preferred people whose skin had an increased number of bacteria but fewer overall types.  The article received significant press coverage and has been viewed almost 10,000 times.

Although a vaccine that blocks malaria transmission is theoretically possible, several obstacles have prevented its development, including producing Plasmodium parasite antigens in a cost-effective manner.  A paper published in May 2012 showed algae can make Plasmodium proteins that can elicit an antibody response.  This approach could bring down overall costs of a vaccine.  Since publication this paper has been viewed over 3,500 times.

A different approach to combatting malaria is to increase the mosquito’s defenses against the parasite.  A paper published in January 2011 showed that it is possible to insert an anti-malarial gene into a specific location in the Anopheles gambiae genome.  This technique decreased infections of Plasmodium yoelii nigeriensis and could be effective against other Plasmodium parasites.  Since publication this paper has received over 2,000 views.

The results from a World Health Organization-led effort to estimate the global incidence of leishmaniasis, a parasitic disease spread by sandflies, published in May 2012.  To obtain an accurate estimate of the disease burden, the authors collected data from 98 countries and 3 territories.  The authors stressed the importance of this in-depth assessment in helping policy makers and aid organizations determine funding priorities for this underreported disease.  The paper has been viewed over 5,000 times.

One strategy parasites use to evade the host’s immune system, initiate infection, and even manipulate host behavior is to imitate the host’s proteins.  A study published in March 2011 presented a method for scanning entire parasite genomes to identify proteins that are mimicking host proteins.  The paper received over 4,000 views and was featured on the This Week in Parasitism podcast.

Finally, a new method for diagnosing infection by Schistosoma mansoni, the parasite that causes schistosomiasis, was published in June 2012.  This method, which is based on detecting the parasite’s DNA, provides greater sensitivity than the most routinely used diagnostic approach, requires only a urine sample, and has a relatively low cost.

If you are at the ICTMM, we hope that you have had a chance to stop by the PLOS booth, pick up one of the PLOS ONE postcards, and meet staff from PLOS Pathogens and PLOS Neglected Tropical Diseases.
