Molecular troublemakers instead of antibiotics?

They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University are researching how it can be possible to prevent the formation of biofilms from the beginning. On this basis, alternatives to antibiotics could be developed, as many pathogens are already resistant. The biologists have published their findings in the scientific journal Frontiers in Microbiology.

Teasing out the microbiome of the Kansas prairie

PNNL scientists have untangled a soil metagenome — all the genetic material recovered from a sample of soil — more fully than ever before, reconstructing portions of the genomes of 129 species of microbes. While it’s only a tiny proportion of the estimated 100,000 species in the sample, it’s a leap forward for scientists who have had only a fraction of that success to date.

MSU criminologist investigates public safety consolidation

In the first comprehensive work of its kind, a Michigan State University criminologist has completed a study on the implementation and outcomes of public safety consolidation — the merging of a city’s police and fire departments. In the study, released recently in a report by the US Department of Justice, professor of criminal justice Jeremy Wilson details that while public safety consolidation can work well for some communities, it isn’t the best solution for others.

Green monkeys acquired Staphylococcus aureus from humans

Many deadly diseases that afflict humans were originally acquired through contact with animals. New research published in ASM’s Applied and Environmental Microbiology shows that pathogens can also jump the species barrier to move from humans to animals. The study, that will publish July 29, shows that green monkeys in The Gambia acquired Staphylococcus aureus from humans.

North America Has Only 1 True Species of Wolf, DNA Shows

North America Has Only 1 True Species of Wolf, DNA ShowsDNA tests of wolves across North America suggest that there is just one species of the canid: the gray wolf. What's more, populations of red wolves and eastern wolves, thought to be distinct species, are actually just hybrids of gray wolves and coyotes that likely emerged in the last couple hundred years, the study found. The findings, published in the journal Science Advances on Wednesday (July 27), could have implications for the conservation of wolves considered endangered in the United States, the researchers say.

4 Florida Zika Cases Were Likely Contracted in the US, Officials Say

Three men and a woman in Florida became infected with the Zika virus, likely after being bitten by mosquitoes in the area, officials said today (July 29). The cases, which are in Miami-Dade and Broward counties, mark the first time that anyone has caught Zika from mosquitoes in the United States. The patients did not travel to another country where Zika is spreading, and did not have sex with a person who had Zika, ruling out these routes of transmission, officials said.

Fungal Disease ‘Valley Fever’ Is Often Misdiagnosed

A fungal infection called valley fever, which can cause mild to severe lung problems (including holes in the lungs), is often misdiagnosed because the symptoms can resemble those of the flu or other illness, experts say. The misdiagnoses can lead to unnecessary medications that don’t treat the fungal infection, according to new guidelines from the Infectious Diseases Society of America. The guidelines stress that primary care doctors should consider the possibility of valley fever in patients who have pneumonia or continuing flu-like symptoms if they live in or have visited the western or southwestern United States, where the fungus is found naturally in the soil.

Death Spiral: 4th Phase of Life May Signal the End Is Near

Death Spiral: 4th Phase of Life May Signal the End Is NearAlthough most of the "death spiral" research has focused on fruit flies, scientists think these studies can offer valuable insight into the last stage of human life as well. "We believe this is part of the process of, basically, genetically programmed death," Laurence Mueller, chair of the Department of Ecology and Evolutionary Biology at the University of California, Irvine, said in an interview with Live Science. Over the past decade, several studies of fruit flies have suggested this spiral toward death can be seen in the drop in reproductive rate (fecundity), according to a review of this research by Mueller and his colleagues, published earlier this year in the journal Biogerontology.

Mysterious Purple Sea Orb Stymies Scientists

Mysterious Purple Sea Orb Stymies ScientistsWith those words, scientists aboard the Exploration Vessel Nautilus uncovered a marine mystery: a small purple orb tucked halfway under a rock off the coast of California. "None of the known species of California pleurobranch are purple," said Susan Poulton, a spokeswoman for the E/V Nautilus expeditions. It was found on July 18, during an E/V Nautilusexploration of Arguello Canyon, west of the Channel Islands National Marine Sanctuary.

Study finds cosmic rays increased heart risks among Apollo astronauts

Astronaut Neil A. Armstrong, Apollo 11 commander, is pictured inside the Lunar Module (LM) while the LM rested on the lunar surface during the Apollo 11 mission in this NASA handout photoBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – Apollo astronauts who ventured to the moon are at five times greater risk of dying from heart disease than shuttle astronauts, U.S. researchers said on Thursday, citing the dangers of cosmic radiation beyond the Earth's magnetic field. The study by researchers at Florida State University and NASA found that three Apollo astronauts, including Neil Armstrong, the first person to walk on the moon, or 43 percent of those studied, died from cardiovascular disease, a finding with implications for future human travel beyond Earth. The research, published in the journal Scientific Reports, was the first to look at the mortality of Apollo astronauts, the only people so far to travel beyond a few hundred miles (km) of Earth.

New crop of robots to vie for space in the operating room

The integrated operating table engineered to move in sync with the da Vinci robot allowing the surgeon to find the best working angle without the need to stop and reposition the robot's arms is shown in SunnyvaleBy Susan Kelly CHICAGO (Reuters) – Even though many doctors see need for improvement, surgical robots are poised for big gains in operating rooms around the world. Within five years, one in three U.S. surgeries – more than double current levels – is expected to be performed with robotic systems, with surgeons sitting at computer consoles guiding mechanical arms. Robotic surgery has been long dominated by pioneer Intuitive Surgical Inc, which has more than 3,600 of its da Vinci machines in hospitals worldwide and said last week the number of procedures that used them jumped by 16 percent in the second quarter compared to a year earlier.

Belgian scientists make novel water-from-urine machine

Belgian scientist Derese drinks water from a machine that turns urine into drinkable water and fertilizer using solar energy, at the University of GhentA team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries. While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid. "We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese.

Great Red Spot storm heating Jupiter’s atmosphere, study shows

A NASA handout of the planet Jupiter/s trademark Great Red SpotBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – Scientists have long wondered why Jupiter's upper atmosphere has temperatures similar to those of Earth, even though the biggest planet in the solar system is five times farther away from the sun. The answer may be The Great Red Spot, an enormous storm big enough to swallow three Earths that has been raging on Jupiter for at least three centuries, a study showed on Wednesday. Using an infrared telescope at Hawaii's Mauna Kea Observatory, scientists discovered that the upper atmosphere above the Great Red Spot – the largest storm in the solar system – is hundreds of degrees hotter than anywhere else on the planet.
