It’s the middle of February and flu season is in full swing. Perhaps you’ve already experienced the body aches, fever, and fatigue that signal the influenza virus. However, there is a chance that these same symptoms were not caused by the flu. A family of viruses called adenovirus is also making the rounds and resembles the flu. The adenovirus kills significantly fewer people than the … Continue reading Achoo! Is Adenovirus making you sick this winter?
by Lara Roach figures by Aparna Nathan There are trillions of cells in the human body, and each one needs nutrient molecules they can convert into energy or useful chemicals to survive, grow, and divide. Cells can get their “fuel” from a variety of sources, but the most common is the sugar glucose, which is abundant in foods like fruit and honey. When cells transform … Continue reading The Circle of Lactate: How cancer cells can reuse their own waste
Naked mole rats are a peculiar species in the animal kingdom for a number of reasons. These wrinkled rodents are immune to cancer, insensitive to pain, and capable of surviving for up to 18 minutes in zero-oxygen environments. Recently, researchers have discovered that in addition to these peculiarities, naked mole rats — unlike all other mammalian species — simply do not age. In 1825, British … Continue reading Naked Mole Rats: An Exception to the Rule
If you want to admire the beauty behind the 2016 Nobel Prize in Physics – topological phases of matter, take a course in topology, followed by graduate-level solid state physics. But if you ask for a concrete application of this topic, you now have an excellent example. Harnessing the concept of topology, scientists have engineered a new way to channel light in lasers. Originally a … Continue reading A Freeway for Light: Topology Protects Lasers from Defects
The colonies in this image display some of the diversity of pigment production in Pseudomonas aeruginosa. The blue-green colonies contain a pigment called pyocyanin, which is known to be toxic to human cells and helps the bacteria establish a niche during infections. The colonies containing a brown halo produce the brown pigment pyomelanin, which is thought to help the bacteria scavenge for iron, an essential … Continue reading Colonies 5
Anyone who has seen Star Wars envisions the future of visual displays as “holograms,” where 3D objects materialize out of light in thin air. However, anyone who has looked at a true hologram will likely have been disappointed at the reality. Not only does the image not pop out in its full glorious 3-dimensions in front of you, but the object is typically only visible … Continue reading Help me “photophoretic-trap volumetric displays.” You’re our only hope.
No, we won’t be seeing designer babies anytime soon. But scientists have successfully cloned monkeys for the first time, establishing a technique that could be used to create better disease models using primates, the closest animals to humans. These cloned monkeys, Zhong Zhong and Hua Hua, are alive and well in China. They were created using the same technology (somatic cell nuclear transfer) used to … Continue reading Monkey see, monkey do: scientists have created the first cloned primates
