Herd immunity won’t solve America’s COVID-19 problem

After months battling the COVID-19 pandemic, the idea of “herd immunity” is back in the news. This has been stoked by reports about the White House’s new pandemic advisor, Scott Altas, who has argued in favor of ending social isolation measures and simply allowing healthy people to get infected. The idea is that the virus wouldn’t spread as quickly once enough people became immune. But trying to reach herd immunity without a vaccine would be a disastrous pandemic response strategy. As mathematics and computer science professors, we think it is important to understand what herd immunity actually is, when it’s a viable strategy and why, without a vaccine, it cannot reduce deaths and illnesses from the current pandemic. What is herd immunity? Epidemiologists define the herd immunity thresho...

Reopening elementary schools carries less COVID-19 risk than high schools – but that doesn’t guarantee safety

Reopening elementary schools carries less COVID-19 risk than high schools – but that doesn’t guarantee safety

While only a fraction of the country’s 50 million public school kids headed back to school in-person this month, many have already found themselves back at home. Within two weeks of opening, multiple states reported school-based COVID-19 outbreaks, and thousands of students and school staff have been quarantined following possible exposure to SARS-CoV-2, the coronavirus that causes COVID-19. Many of these districts are in areas with high community spread of COVID-19, and some didn’t enforce social distancing or require face masks. Our team of infectious disease epidemiologists collected data in the San Francisco Bay Area and ran computer simulations to examine how school closures and reopenings can affect the spread of COVID-19. What we learned points to three key strategies for minimi...

African Americans have long defied white supremacy and celebrated Black culture in public spaces

From Richmond to New York City to Seattle, anti-racist activists are getting results as Confederate monuments are coming down by the dozens. In Richmond, Virginia, protesters have changed the story of Lee Circle, home to a 130-year-old monument to Confederate General Robert E. Lee. It’s now a new community space where graffiti, music and projected images turn the statue of Lee from a monument to white supremacy into a backdrop proclaiming that Black Lives Matter. This isn’t a new phenomenon. I’m a historian of celebrations and protests after the Civil War. And in my research, I have found that long before Confederate monuments occupied city squares, African Americans used those same public spaces to celebrate their history. But those African American memorial cultures have often been o...

A Student’s Perspective on Finding Hope, Love, Justice, and Common Humanity

Marching in a steady stream of people shouting familiar slogans through face masks, some of them awkwardly trying to socially distance, my first protest was fairly different from anything I’d have imagined before 2020. That didn’t make it any less powerful. The speeches given by religious and local Black community leaders, united after the police killing of George Floyd, drew in the hundreds of passionate, chanting protesters who were occupying City Hall and stunned them into mournful silence. Nor did it make it any less necessary. Mapping Police Violence data found that Black people in America are not only 3 times more likely to be killed by police than White people, they are also 1.3 times more likely to be killed while unarmed, culminating this year with the tragic deaths of George Flo...

A smart second skin gets all the power it needs from sweat

The big idea Skin is the largest organ of the human body. It conveys a lot of information, including temperature, pressure, pleasure and pain. Electronic skin (e-skin) mimics the properties of biological skin. Recently developed e-skins are capable of wirelessly monitoring physiological signals. They could play a crucial role in the next generation of robotics and medical devices. My lab at Caltech is interested in studying human biology and monitoring human health by using advanced bioelectronic devices. The e-skin we have developed not only analyzes the chemical and molecular composition of human sweat, it’s fully powered by chemicals in sweat. Why it matters Existing e-skins and wearable devices primarily focus on monitoring physiological parameters like heart rate and can’t assess hea...

Insider trading by members of Congress may be difficult to prove

Recent allegations regarding stock trading by members of Congress in the midst of the COVID-19 pandemic have raised calls for the investigation of these politicians for illegal “insider trading.” But successfully prosecuting such cases will be very difficult. Even federal judges struggle with writing clear instructions to lay jurors in insider trading cases. Often, verdicts are reversed on appeal due to errors in explaining complicated legal terms. There are two different provisions of law that could apply to the trading activity of senators and congressional staff. Members of Congress and staff could run afoul of either or both of these laws. But proving a violation and convicting them is not likely. Stock Act and securities law The first provision is a rule known as Rule 10(b)(5) afte...

Pregnant in a time of coronavirus – the changing risks and what you need to know

“So, being pregnant and delivering in a pandemic … what’s that gonna look like?” That question, sent to me by a colleague who is both a registered nurse and an expectant mother, stopped me in my tracks. As an OB-GYN physician, I naturally focus on the science of health care. Her email reminded me of the uncertainty expectant mothers now face as health risks and the health care system around them change amid this coronavirus pandemic. While knowledge about the new coronavirus disease, COVID-19, is rapidly evolving and there are still many unknowns, medical groups and studies are starting to provide advice and answers to questions many expecting families are asking. Do pregnant women face greater risk from COVID-19? So far, the data on COVID-19 does not suggest pregnant women are at higher...

12 productive things you can do to feel better about being stuck at home

Now that the coronavirus has sent workers and students home, closed businesses and canceled events, it’s going to be important to create new routines and find meaningful ways to spend our long days at home. The following organizing tasks are simple and will help you structure your day and create a small sense of control. Order picture frames and albums: Do you have a stack of photos you have been meaning to put in frames or photo albums? If so, take a few minutes online to find options that will work for you, and place the order. Depending on how long social distancing lasts, you may even have time to put those photos into the frames and albums. Send notes: Write those thank-you cards that you have had on your to-do list for the past few months. If you don’t have any thank-you notes to s...

Love in the time of the coronavirus: Do you turn your back when someone offers you a hand, a kiss or a hug?

The toll of the coronavirus grows, with California under a state of emergency, and more than 150 cases and 11 deaths reported in the U.S.. Also, more than 300 million school children worldwide are facing closures of their schools. What does this mean for you in your personal life? We asked Brian Labus, professor of public health at the University of Nevada Las Vegas, about what kinds of physical contact are safe while COVID-19 is spreading. We are exposed to numerous viruses from our day-to-day interactions with other people all the time. However, our risk of being infected by a simple greeting usually isn’t in the forefront of our minds. The spread of COVID-19 has changed that. Conferences have banned handshakes, churches have changed their worship services, and even politicians have ch...

Connecting The Dots Between Slavery And Prison

Students suing the Ivy League say rather than helping to dismantle the system of “human caging,” the school is profiting from it. “Today we take an important step in the effort to explore the complexities of our past and to restore this painful dimension of Harvard’s history to the understanding of our heritage. The past never dies or disappears. It continues to shape us in ways we should not try to erase or ignore.” Harvard University President Drew Faust spoke these words in 2016 as she stood alongside U.S. Rep. John Lewis of Georgia in front of the university’s famed Wadsworth House. They unveiled a plaque in remembrance of enslaved people who served the university centuries ago. In 2019, current President Lawrence Bacow renewed the pledge. But it would appear Harvard, which had a p...
