Researchers developed biomaterial-based inks that respond to and quantify chemicals released from the body or in the environment by changing color. Multiple inks can be screen printed onto clothes or even face masks at high resolution, providing a detailed map of human response or exposure.

Researchers studied how staff at fertility clinics view the assessments that childless couples and women undergo in order to access assisted reproduction. It emerges in the interviews that the assessment of the potential parents is based on the child's future welfare and on the responsible use of public resources.

A new study finds a causal link between sleep deprivation and death. In sleep-deprived fruit flies, death is preceded by the accumulation of molecules known as reactive oxidative species in the gut. When fruit flies were given antioxidant compounds that neutralize ROS, sleep-deprived flies remained active and had normal lifespans. The findings may one day inform new approaches to counteract the harmful effects of insufficient sleep in humans.

Parents pass genes along to their offspring which equip them for their future life. In recent years, research has shown that the reality is much more complex and that parents endow much more than just genes. A new study reveals that active epigenetic modifications are also passed from one generation to the next.

Researchers have developed synthetic microbial spores that can be safely introduced onto objects and surfaces at a point of origin, such as a field or manufacturing plant, and be detected and identified months later. The approach can help determine the source of foodborne illnesses.

Sleep disruption has been shown to be associated with an increased risk of atherosclerosis, but the mechanism has been unclear. A new study reveals that fragmented sleep exacerbates atherosclerosis and may raise the risk of stroke via an effect on inflammatory pathways.

Research shows that energy constraints on a system, coupled with an intrinsic property of systems, push silicon neurons to create a dynamic, at-a-distance communication that is more robust and efficient than traditional computer processors. And it may teach us something about biological brains.

Adult neurogenesis, in which new neurons are generated within the hippocampus in the fully developed adult brain, occurs in mice -- but how new neurons are functionally integrated into existing brain circuitry has remained largely unknown. A study now shows an important new role for neurons generated during adulthood in consolidating memories during sleep in mice.

Vaginal Lactobacillus bacterial strains largely perform better than strains currently used in probiotics for vaginal health, according to a new study. The findings suggest that a vaginal health probiotic that includes top-performing vaginal Lactobacillus strains may improve treatment options for bacterial vaginosis.

The assumption that dietary restriction (and drugs that mimic its effects) will extend both lifespan and healthspan jointly has come under question, based on research involving 160 genetically distinct strains of fruit fly. Noting that results may foreshadow what will happen in humans eating a Spartan diet, researchers report that thirteen percent of the strains were more vigorous, yet died sooner with dietary restriction; 5 percent lived longer, but spent more time in poor health.

In early March, when most Americans began social distancing, the hope was that life would get back to normal after just a few weeks. It’s become clear now that some distancing will be needed for many more months, or even years, to keep the coronavirus at bay. But quarantine fatigue is real. Abstaining from all social contact for the long haul won’t be a sustainable option for most people. So, how can we make decisions about socializing during the coronavirus pandemic?

Risk isn’t binary

Public health messaging over the past several months has focused on staying home as much as possible. Staying home alone or with your household members is still the lowest-risk choice you can make with respect to catching or spreading the coronavirus. Being in a crowded indoor environment is the highest-risk choice.

But risk isn’t binary, and there’s a lot in between those two options. Thinking about a spectrum of risk can help you choose the lowest-risk options for socializing that will be sustainable for you in the long term.

How can you assess the spectrum of risk?

The risk of contracting or transmitting the coronavirus depends on many factors. Here are some important considerations when you’re assessing risk to yourself and others.

  • Know what’s happening with virus transmission in your community. Try to keep tabs on what’s happening with community spread where you live. For example, pay attention to whether the number of new cases, hospitalizations, and deaths are high or low, or increasing or decreasing. Some regions are opening while these numbers remain fairly high, so you may choose to be more conservative with your social contact than the current recommendations in your area. Just because the hair salon is open doesn’t mean you have to get a haircut.
  • Consider vulnerability to the coronavirus. If you or your social contacts are particularly vulnerable to the coronavirus, either because of older age or underlying health conditions, factor this into your assessment of risk when making decisions about interactions outside of your household.
  • Evaluate the risk of the activity, which includes its duration and setting. The highest risk for transmission is with close contact, prolonged interaction, and enclosed environments. In contrast, keeping a distance of at least six feet, brief interactions, and outdoor settings will keep risk lower. Sitting indoors a few feet away from a friend and having a long talk is a higher-risk situation than going for a stroll or chatting briefly with that person outdoors. Face coverings can further reduce risk, and are particularly important when interacting with people in close proximity or indoors. It also helps to use other protective measures, including frequent handwashing.

The benefits of being social

Health is more than just disease prevention. For many people, being healthy requires social interactions with friends and family, spending time outdoors, exercise, physical intimacy, and other pleasures of life. When making decisions about social contact during the coronavirus pandemic, you will need to weigh the risk of the interaction against the potential benefits to your overall health.

Harm reduction strategies can help

Unlike abstinence-only messaging, which simply tells people to stay home, a harm reduction approach meets people where they are by accepting that it isn’t always possible to eliminate risk. It supports people in making lower-risk — but not necessarily zero-risk — choices that are sustainable for them, and offers strategies to reduce any potential harms. The abstinence-only and harm reduction approaches share the same goal of reducing illness and death, but from what we know about HIV, substance use, and other areas of health, harm reduction is far more likely to work.

Several examples of harm-reduction approaches to social contact have been adopted outside of the United States. Acknowledging that single people may need physical intimacy, the Netherlands has suggested that people find a seksbuddy, with one consistent sex partner being much less likely to spread the coronavirus than having multiple partners. Several provinces in Canada have issued guidance on “double bubbles,” in which two households agree to socialize exclusively with each other without the need for physical distancing.

It’s true that every additional social interaction increases risk, but with continued social distancing from other individuals and households, harm reduction approaches might help people forego higher-risk activities, like crowded house parties, over the long term. As we enter the fourth month of this pandemic, with many more months ahead, it’s time to start thinking about sustainability.
