Researchers are exploring the relationship between microbial natural products and the gene clusters that enable their production. By learning to recognize what genes lead to what types of products, they hope to use genome sequencing to speed discovery of new natural products that may have key therapeutic properties.
An oncogene, UPS21, has been confirmed as a frequently amplified gene in pancreatic ductal adenocarcinoma, the most common and often lethal form of pancreatic cancer. The discovery could lead to new treatment options.
Scientists have been researching the effect of precipitation and population size on rising temperatures in cities compared with the surrounding countryside. They have found that more green spaces can help to lower temperatures in urban zones -- but not everywhere.

Eighteen people die every day waiting for transplants, and a new patient is added to the organ transplant list every 10 minutes. Much of the problem surrounds the lack of registered donors. New research provides incentives that could lead to a solution and ultimately save lives.
Patients in the United States and Canada are seven times as likely as those in Sweden to receive a prescription for opioid medications after surgery, according to a new multi-institutional study. Though the United States and Canada had similar prescription rates, patients in the U.S. were prescribed a much higher dosage - as measured by the total morphine milligram equivalents (MME).
A millipede-like creature from 550 million years ago is among the earliest examples of this.
A traumatic brain injury is often easily suspected and can be confirmed and treated if necessary following an injury using a blood analysis, but scientists are reporting that even one mild blast to the brain can cause very subtle but permanent damage as well. Urine analysis taken within one week of a mild to traumatic brain injury also can provide faster diagnosis and treatment for such injuries.

Light-emitting diodes made of indium gallium nitride provide better luminescence efficiency than many of the other materials used to create blue and green LEDs. But a big challenge of working with InGaN is its known dislocation density defects that make it difficult to understand its emission properties.
The Global Precipitation Measurement mission or GPM core satellite provided information about the rate in which rain was falling within the Eastern Atlantic Ocean's latest tropical storm, Gabrielle.
Intrepid Brazilian and British scientists say they have located the Amazon's tallest tree in northern Brazil, untouched by a spate of wildfires that have raged in the rainforest for weeks. The scientists say they located an unusually large specimen of the giant Dinizia Excelsa species -- measuring 88 meters (288-feet) with a circumference of 5.50 meters -- in a sanctuary of other Dinizia trees....
A Himalayan lake was the final resting place of an estimated 800 skeletons. Researchers still don't know what killed...
A new vaccine has the potential to treat and prevent toxic shock caused by invasive streptococcal disease, which kills more than 160,000 people every year. When ISD occurs, some strains can make more toxins than others and cause streptococcal toxic shock syndrome (STSS). Now that antibodies have been generated, the next step would be to make monoclonal antibodies that could be suitable for a human...
Grey squirrels eavesdrop on the chatter between nearby songbirds as a sign of safety.
A new mathematical model provides support for environmental taxation, such as carbon taxes, as an effective strategy to promote environmentally friendly practices without slowing economic growth.
Animals not only tune in to alarm cries or ‘all-clear’ signals from other speciesSquirrels eavesdrop on the chatter of songbirds to work out whether the appearance of a predator is cause for alarm, researchers have found.Animals including squirrels have previously been found to tune in to cries of alarm from other creatures, while some take note of “all-clear” signals from another species...
Plastic pollution has entered the fossil record, research showsPlastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the...
when they feel safe to communicate the absence of danger or share their location. This "chatter" from multiple bird species could therefore be a useful cue to other creatures that there is no imminent threat.
A new mathematical model provides support for environmental taxation, such as carbon taxes, as an effective strategy to promote environmentally friendly practices without slowing economic growth. Xinghua Fan and colleagues at Jiangsu University, China, publish their model and findings in the open-access journal PLOS ONE on September 4, 2019.

In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world's cities, heat island intensity can largely be explained by a city's population and precipitation level, researchers have reported. The analysis suggests that cooling cities by planting more vegetation may be more effective in drier regions...

A recent study investigated around 100,000 localized seismic events to search for patterns in the data. Scientists discovered that earthquakes of differing magnitudes have more in common than was previously thought. This suggests development of early warning systems may be more difficult than hoped. But conversely, similarities between some events indicate that predictable characteristics may aid...
