Harness the world’s aquatic ‘blue’ food systems to help end hunger

Harness the world’s aquatic ‘blue’ food systems to help end hunger

An editorial in Nature, says: Next week, world leaders will gather for the United Nations Food Systems Summit. The event will be hosted by UN secretary-general António Guterres, with the aim of giving a much-needed boost to efforts to get the agency’s flagship Sustainable Development Goals back on track. One of these goals is to end hunger by 2030. Nearly 700 million people (almost 9% of the world’s population) go hungry; of those, 250 million are potentially on the brink…

Human gut bacteria could be accumulating our medications without our understanding the impact

Human gut bacteria could be accumulating our medications without our understanding the impact

Science Alert reports: When we take medicine, there are often unintended consequences. In the most common scenarios, these are known as side effects. But ‘side effects’ don’t begin to encompass the multitude of strange things that can happen when various compounds enter our system. Sometimes, these unintended consequences occur after drugs physically exit the body, with medicine finding a second life in animals accidentally exposed to the formulations downstream. Yet even before drugs have a chance to leave your body,…

Most people don’t need a Covid vaccine booster, new review says

Most people don’t need a Covid vaccine booster, new review says

The New York Times reports: None of the data on coronavirus vaccines so far provides credible evidence in support of boosters for the general population, according to a review published on Monday by an international group of scientists, including some at the Food and Drug Administration and the World Health Organization. The 18 authors include Dr. Philip Krause and Dr. Marion Gruber, F.D.A. scientists who announced last month that they will be leaving the agency, at least in part because…

Our most reliable pandemic number is losing meaning

Our most reliable pandemic number is losing meaning

David Zweig writes: At least 12,000 Americans have already died from COVID-19 this month, as the country inches through its latest surge in cases. But another worrying statistic is often cited to depict the dangers of this moment: The number of patients hospitalized with COVID-19 in the United States right now is as high as it has been since the beginning of February. It’s even worse in certain places: Some states, including Arkansas and Oregon, recently saw their COVID hospitalizations…

Can an omnipresent virus be turned into a manageable risk?

Can an omnipresent virus be turned into a manageable risk?

Scott Gottlieb writes: This pandemic will eventually be over, and the Delta surge—in which most of those not yet vaccinated against the coronavirus could become infected—may well be America’s last destructive wave. But just because we’re eager to move past the virus doesn’t mean it’s finished with us. In our large, open, and globally connected society, getting to zero COVID, the goal that Australia and New Zealand have pursued, is as politically unrealistic as it is biologically implausible. Americans are…

Biden vaccine mandate raises longstanding legal questions, experts say

Biden vaccine mandate raises longstanding legal questions, experts say

USA Today reports: Throughout the pandemic, public health experts have frequently pointed to the Supreme Court’s 1905 decision in Jacobson v. Massachusetts to justify state vaccine mandates. But experts say that case is unlikely to have much influence over the legal challenges raised to the new Biden administration policy. Henning Jacobson, a pastor from Cambridge, Mass., refused a smallpox vaccination during an outbreak of the disease in 1905, citing bad reactions he had to shots in the past. He was…

Pfizer’s Covid vaccine could be authorized for children aged 5-11 but may pose risk for boys

Pfizer’s Covid vaccine could be authorized for children aged 5-11 but may pose risk for boys

The Guardian reports: Healthy boys may be more likely to be admitted to hospital with a rare side-effect of the Pfizer/BioNTech Covid vaccine that causes inflammation of the heart than with Covid itself, US researchers claim. Their analysis of medical data suggests that boys aged 12 to 15, with no underlying medical conditions, are four to six times more likely to be diagnosed with vaccine-related myocarditis than ending up in hospital with Covid over a four-month period. Most children who…

Inflammatory responses to pathogens changed dramatically during the Neolithic period

Inflammatory responses to pathogens changed dramatically during the Neolithic period

Science reports: When early farmers of the Vinca culture first sowed barley and wheat 7700 years ago in the rich soil of the Danube River and its tributaries, they changed more than their diet: They introduced a new way of life to the region. They crowded together in mud huts, living cheek by rump with aurochs, cows, pigs, and goats—and their poop—in settlements that eventually swelled to thousands of people. Togetherness brought a surge in diseases such as influenza, tuberculosis,…

A new way to think about clean air

A new way to think about clean air

Sarah Zhang writes: When London vanquished cholera in the 19th century, it took not a vaccine, or a drug, but a sewage system. The city’s drinking water was intermingling with human waste, spreading bacteria in one deadly outbreak after another. A new comprehensive network of sewers separated the two. London never experienced a major cholera outbreak after 1866. All that was needed was 318 million bricks, 23 million cubic feet of concrete, and a major reengineering of the urban landscape….

Jose Luis Pelaez Inc/Digital Vision via Getty Images By Paul Shafer, Boston University and Alex Hoagland, Boston University Many Americans breathed a sigh of relief when the Supreme Court left the Affordable Care Act (ACA) in place following its third major legal challenge in June 2021. This decision left widely supported policies in place, like ensuring coverage regardless of preexisting conditions, coverage for dependents…

Number of daily steps to good health

Number of daily steps to good health

Science Alert reports: In the latest study to explore this territory, a team led by physical activity epidemiologist Amanda Paluch from the University of Massachusetts, Amherst tracked a cohort of over 2,000 middle-aged Black and White men and women, sourced from four different US cities. The group, with an average age of just over 45, wore accelerometers that tracked their daily step count and step intensity during waking hours, as they went about their lives. The experiment began back in…

Another study promoting ivermectin has suspect data

Another study promoting ivermectin has suspect data

BuzzFeed News reports: For anti-vaccine activists, the clinical trial results couldn’t have been better. The drug ivermectin, scientists in Argentina announced last year, prevented 100% of COVID-19 infections. That glowing finding helped spark a craze for the decades-old medication, which is normally used to delouse people and deworm livestock, and drive the perception that it is a silver bullet against the pandemic. “If you take it, you will not get sick,” an ivermectin-boosting physician told a Senate committee in December,…

Risk of breakthrough infections remains very rare, three studies find

Risk of breakthrough infections remains very rare, three studies find

NBC News reports: The Covid-19 vaccines continue to offer strong protection against severe illness and hospitalization, according to research on more than 1 million people published Wednesday in The Lancet Infectious Diseases. The findings come as the United States prepares to begin offering booster shots to all Americans later this month — a decision driven in part by data federal officials have said indicates the vaccines’ ability to curb infections may be waning. But protection against the most severe forms…

Medical science is failing millions of Covid long-haulers

Medical science is failing millions of Covid long-haulers

Ed Yong writes: While watching the scientific community grapple with long COVID, I have thought a lot about a scene in The Lord of the Rings. Faced with impending doom, the hobbits Merry and Pippin ask the powerful treelike ents for help. But despite the urgency of the situation, the ents are slow. They meet for hours, and after a lot of deliberation, they announce that they’ve agreed that the hobbits are not orcs. The hobbits, who already knew that,…

Ending an eviction moratorium increases Covid-19 hazard, study finds

Ending an eviction moratorium increases Covid-19 hazard, study finds

MIT News reports: Ending an eviction moratorium for renters makes people in a community significantly more likely to contract Covid-19, according to a new study co-authored by MIT researchers. The study uses the variable timing of state-level moratoriums, issued and terminated at different points during the Covid-19 pandemic, to quantify their effect. It is the first study to identify the individual-level risk for people in different social circumstances, due to eviction moratoriums ending. The increased risk runs throughout communities, the…

Vaccines could affect how the coronavirus evolves – but that’s no reason to skip your shot

Vaccines against COVID-19 are the safest – and fastest – way to prevent the spread of variants. Luis Alvarez/ DigitalVision via Getty Images By Andrew Read, Penn State Takeaways A 2015 paper on a chicken virus showed vaccines could enable more deadly variants to spread – in chickens. But that outcome is rare. Only a minority of human and animal vaccines have affected the evolution of a virus. In most of those cases, evolution didn’t increase the severity of the…
