Saturn's rings formed 4.4 billion years ago
Earth and Planetary Science Latest findings suggest that Saturn's rings originated around 4.4 billion years ago. NASA's Cassini spacecraft, which has been orbiting Saturn since 2004, has measured the rate at which dust from outside the Saturn sy ...
Can antibiotic intake in early life lead to obesity in adulthood?
Medicine, Health, and Nursing Researchers from New York University Langone Medical Center found that low doses of antibiotics in the early life of mice led to obesity when they grew up due to long-lasting consequences of the antibiotics on gut microbes. F ...
Chemists are racing to create 'robo-chemist,' a synthesis machine
Chemistry and Materials Science There is a growing interest paired with attempts in creating a synthesis machine or a ‘robo-chemist’ that would take over the traditional organic chemistry. Such a device would offer a diversity of compounds for investigati ...
Did methane release leave behind the mysterious Siberian crater?
Earth and Planetary Science In mid-July, a mysterious 30-meter-wide crater was spotted in the frozen Yamal peninsula in Siberia. Although many theories abounded over the cause of the crater, researchers in Russia believe the mysterious hole was left behin ...
Exposure to dim light at night hastens human breast cancer tumor cells’ growth
Medicine, Health, and Nursing The growth of human breast cancer tumors implanted in rats speeded up by 2.5 times when they were exposed to dim light at night according to a study conducted by Steven Hill and his team at Tulane University School of Medicin ...
CRISPR/Cas9 method removes HIV from human cells
Biochemistry, Genetics, and Molecular Biology Researcher Kamel Khalili and his team at Temple University in Philadelphia, Pennsylvania, used the CRISPR/Cas9 genome-editing system to remove HIV from several human cell lines, including microglia and T cells ...
Scientists create biological pacemaker using gene therapy
Biochemistry, Genetics, and Molecular Biology Eduardo Marbán, a cardiologist at Cedars-Sinai Medical Center in Los Angeles, California, and his team has developed a method to keep heart cells outside the sinoatrial node beating, which is less invasive tha ...
Were fluctuating oxygen levels responsible for the “boring billion?”
Earth and Planetary Science Life on Earth began 260 million years after the planet’s early atmosphere witnessed two major spikes in oxygen concentration — the first one is called the ‘great oxygenation event,’ which occurred one roughly 2.3 billion years ...
Humans dislike spending time with their own thoughts
Psychology and Neuroscience Social psychologist Timothy Wilson at the University of Virginia in Charlottesville and his team found that most people had a “disengaged mind.” Wilson’s team conducted a study in which participants were asked to spend 15 minut ...
Mosquitoes are attracted to infected mammals
Plant and Animal Science Scientists from the Swiss Federal Institute of Technology (ETH Zürich) and their colleagues combined analytical chemistry and behavioral assessment to study the relation between malaria-infected mammals and mosquitoes. They found ...
