Particle Physics Revolutionizes Archaeology

How many mysteries are buried within Egypt’s Great Pyramid of Giza? Whatever the answer, we know of one more. Scientists recently discovered an unknown void in the heart of the pyramid. Over the past centuries, archaeologists have unveiled many features of the pyramid’s interior. If you get a tour today, you can venture along its Grand Gallery, into the king’s chamber, and touch the 4,500-year-old walls … Continue reading Particle Physics Revolutionizes Archaeology

How Our Immune System Causes Heart Attacks (and Cancer)

by Giulia Notarangelo figures by Abagail Burrus A drug that might significantly reduce the risk of heart attack and lung cancer is being hailed by researchers as the biggest breakthrough in the treatment of cardiovascular disease since the introduction of cholesterol-lowering drugs called statins over 30 years ago. Despite the fact that drug companies sell over $30 billion worth of statins annually, roughly 600,000 people still … Continue reading How Our Immune System Causes Heart Attacks (and Cancer)

Saying goodbye to our first interstellar visitor

No, I don’t mean Matthew McConaughey. A few weeks ago, our first interstellar visitor flew nearby Earth and now is on its way back out of our solar system. While these types of extra-solar system objects have long been expected to exist as a bi-product of planet formation in nearby solar systems, this is the first ever detected – an event scientists have been waiting decades for. Continue reading Saying goodbye to our first interstellar visitor

Conservation spending proven to make a difference

The world is currently experiencing its sixth mass extinction event. Species are disappearing at an estimated 1000x the expected normal rate of extinction (roughly 5 species per year). Conservation efforts around the world are trying to reduce the rate of biodiversity loss, but they are hindered by the lack of hard evidence linking conservation spending to biodiversity improvements. A team led by University of Oxford researchers … Continue reading Conservation spending proven to make a difference

How stress can change your DNA

A first link between chronic stress, genetics, and mental illness has recently observed in mice. Researchers have discovered that the genes of mice exposed to chronic stress change over time. Modifications were most associated with genes related to a variety of mental illnesses, such as depression, autism spectrum disorder, and schizophrenia.1-3 How exactly are genetics, stress, and mental illness related? DNA, serves as instructions for cells and is broken up into … Continue reading How stress can change your DNA

CRISPR 2.0: Genome engineering made easy as A-B-C

CRISPR 2.0 is causing quite the ruckus in the scientific community. Why? Imagine that you had written a note in permanent marker, but later decided you wanted to change a single word. Without the ability to erase, your options would be limited, and further changes might make the note illegible. New CRISPR technologies, or “base editors,” behave as molecular erasers. These molecular erasers enable you to very precisely … Continue reading CRISPR 2.0: Genome engineering made easy as A-B-C

Neutron star collision provides a glimpse of the future of astrophysics

Albert Einstein predicted the observation of gravitational waves from the merger of black holes over a century ago. This astrophysical phenomenon remained elusive, however, until their detection at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the summer of 2015. This Nobel Prize-winning discovery added a new technique to the observational astronomy tool box and propelled LIGO onto the public scene. Since their initial discovery, gravitational waves have been … Continue reading Neutron star collision provides a glimpse of the future of astrophysics
