‘Double-sided tape’ could replace surgical stitches

Sutures are commonly used to close wounds in the skin or other tissues. Similar to sewing fabric, the doctors will use a needle attached to a thread to penetrate the tissue and close the edges of the wound together, facilitating quick healing. Although surgical sutures have been used for thousands of years, they still have some limitations: 1) the needles cause some damage to the … Continue reading ‘Double-sided tape’ could replace surgical stitches

Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air

In the Canadian town of Squamish, there’s a small building with a massive fan on its purple roof. The fan is rapidly pulling outside air into the facility. The air enters the outdoors again, but it’s not quite the same. About 75% of the carbon dioxide (CO2) is gone. Run by the company Carbon Engineering (CE), the building is the pilot plant for their technology … Continue reading Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air

Nanowires

  Nanowires are thin structures measuring 0.000000001 meters in diameter, which is so thin that they essentially behave as if they only have one-dimension. This one-dimensional nature gives nanowires a ton of interesting electrical and magnetic properties, which are super useful in electronics and medical devices, especially as they are getting smaller and smaller. Nanowires can be made from a number of different materials. The grey columns in this … Continue reading Nanowires

The Chemistry Nobel: Evolving proteins into better medicines and biofuels

It’s that time of year – Nobel Prize season! This year, the Chemistry Nobel prize was awarded to three scientists: one half to Frances Arnold “for the directed evolution of enzymes,” and the other half to George Smith and Sir Gregory Winter “for the phage display of peptides and antibodies.” What exactly are these award-winning technologies and how have they impacted society? ‘Directed evolution of … Continue reading The Chemistry Nobel: Evolving proteins into better medicines and biofuels

Building the Smallest Chemical Beaker

Typically, if you want to understand the foundation of something, building from the ground up sounds like a sensible approach. However, researchers in Dr. Ni’s group at Harvard have taken this idea a step further by building molecules one atom at a time. The group’s goal is to better understand the minimal requirements and exact properties of chemical reactions. For comparison, while every chemistry class … Continue reading Building the Smallest Chemical Beaker

The FDA Approves the First Non-Opioid Drug to Ease Opioid Withdrawal Symptoms

It is 2018, and we are well on our way towards curing cancer. Yet, as we look around, we find another nightmare haunting our society that is as formidable, if not more so, as it has been for centuries. That nightmare is opioid addiction.  Overcoming opioid addiction is notoriously difficult, because of the excruciating symptoms associated with the withdrawal process, during which the only aid … Continue reading The FDA Approves the First Non-Opioid Drug to Ease Opioid Withdrawal Symptoms
