In May 2018, California passed a law requiring that almost all new homes built in the state must have solar power after January 2020. California becomes the first state to pass such a law to support Governor Brown’s initiative to reduce carbon emissions by 40 percent by 2030.
Before the advent of microscopy, scientists such as Leonardo da Vinci had to surreptitiously dissect the human body to gather insights into its functional anatomy. Now, two-photon microscopy has further advanced our ability to peer into living tissues with minimal intervention. For instance, two-photon microscopy allows your window of vision to penetrate through a living mouse’s brain and marvel at a neuronal cell’s inner workings. Pan the microscope underneath the skin and you will see hair follicle stem cells dividing and regenerating in real-time. Over a tumor bulge, you can observe metastatic cancer cells migrating and invading blood vessels. The mechanics of this visual journey relies on two photons meeting each other at the same place at the right time.
Outside of normal sneezing exists an entirely separate group of sneezing-related phenomena. One particularly common condition that affects up to 35% of Americans is called the photic sneeze reflex. This reflex is conveniently abbreviated as ACHOO (Autosomal Dominant Compulsive Helio-Ophthalmic Outburst syndrome), so named because it involves sneezing in response to sudden increases in light intensity.
If you are 18 years of age, you have never known a world without a camera phone. Today, the quality of digital phone cameras is crucial to social media platforms, to businesses seeking visibility, and to people documenting as much of their lives and environments as possible. In this article, we will explore the functions of camera mechanics that created one of the most essential remote sensing devices in human history.
Jellyfish and fireflies – what is something these two animals have in common? They both glow! This emission of light by these organisms is called bioluminescence, a term combining the Greek word “bio” meaning “life” and the Latin word “lumen” for “light.” Bioluminescence is produced through a chemical reaction that occurs within cells. Over the years, scientists have gained an appreciation for bioluminescence and have adapted it not only for research and medical purposes, but also as a platform for their passion for art. This artwork, as captivating as the living organisms that it originates from, has become a beautiful way of introducing people to the wonders of biology.
Light has fascinated humanity since the beginning of civilization. From the alignment of the rocks at Stonehenge to the second line of the Torah: “Then God said, ‘Let there be light;’ and there was light,” virtually every human culture has appreciated the importance of light for survival.
According to the National Center for Complementary and Integrative Health (NCCIH), nearly 100 million American adults report suffering from chronic or severe pain. Additionally, pain is a condition that disables more Americans in the US than heart disease, cancer and diabetes combined. The most recent definition of chronic pain is as follows, “a distressing experience associated with actual or potential tissue damage with sensory, emotional, cognitive, and social components.” In accordance with the high prevalence of chronic pain, reports from the Centers for Disease Control concluded that the most commonly prescribed class of medication in the US are opioid analgesics despite a lack of evidence supporting their efficacy in treating chronic pain.
3-D printing. Virtual reality. Artificial intelligence. Self-driving cars. Robotic surgery. Gene editing. Higgs boson. The list goes on. These recent breakthroughs are becoming household words (and items), and they are a testament to the rapid expansion of our society’s technological capabilities. In the world of medical research, however, this paradigm has recently shifted towards exploring natural biological systems rather than focusing on the typical research areas of medical devices and drug development.
