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

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

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

Ripples in Spacetime from Colliding Stars detected by LIGO-Virgo Collaboration

The LIGO collaboration has reported the merger of two neutron stars. Another collaboration (Virgo) was able to detect the signal. Scientists were able to make a tighter estimate on where the merger happened. The merger suggests gravity propagates at the speed of light, proves that photons (light particles) are even closer to massless than previously measured, and heavy elements like platinum might primarily come from colliding stars instead of supernovae. Continue reading Ripples in Spacetime from Colliding Stars detected by LIGO-Virgo Collaboration

November 1 – What Genes Cannot Tell: The role of epigenetics in determining who we are

Time: 7-9 p.m., Wednesday, November 1st Location: Armenise Amphitheater at Harvard Medical School, 200 Longwood Avenue, Boston (link to directions) Speakers: Nava Gharaei, Kalki Jukreja, and Jenny Zheng All the cells in our body have the same DNA, and yet a stomach cell is able to digest food while a heart cell pumps blood. Similarly, genetically identical individuals have the same DNA, yet they develop into unique individuals … Continue reading November 1 – What Genes Cannot Tell: The role of epigenetics in determining who we are

October 25 – Here Comes the Sun: Harnessing the power of renewable energy

Time: 7-9 p.m., Wednesday, October 25th Location: Armenise Amphitheater at Harvard Medical School, 200 Longwood Avenue, Boston (link to directions) Speakers: Emily Kerr and Justin Teesdale Over the last few years, electricity generation from renewable sources has grown at a remarkable pace and is projected to almost double by 2025. As we rely more on these green energy sources, how do we transform a power source that only … Continue reading October 25 – Here Comes the Sun: Harnessing the power of renewable energy
