The Next Era of Gene Editing Will Be Disease Agnostic

At the WIRED Health summit last week, Harvard biochemist and gene-editing pioneer David Liu says later this year his lab plans to report on a single gene-editing strategy that could treat many unrelated diseases. He calls it disease-agnostic therapeutic gene editing. “It sounds sort of crazy, but there’s actually a very good molecular biology reason why this could be possible,” he told the audience in Boston, stopping short of details. Gene-editing treatments are currently being developed for

Whole-Genome Sequencing Will Change Pregnancy

The world of pregnancy is going to radically change, predicts Noor Siddiqui. “I think that the default way people are going to choose to have kids is via IVF and embryo screening,” she said at the WIRED Health summit last week. “There’s just a massive amount of risk that you can take off of the table.” Siddiqui is the founder and CEO of Orchid, a biotech company that offers whole-genome screening of embryos for IVF. By analyzing the DNA of different embryos before selecting which one to implant

New Bacteria Discovered in Flies Could Sicken Humans

A new species of bacteria has come to light in Brazil. It’s genetically similar to two other disease-causing bacteria from the Andes, which are known to infect humans through sand fly bites. According to a study published this summer in the journal Acta Tropica, researchers have discovered a new bacteria species in phlebotomine insects (sand flies) in the Amazon National Park in Brazil’s state of Pará. Its DNA is similar to that of two Andean bacteria in Peru, Bartonella bacilliformis and Barto

RFK Jr’s plan to improve America’s diet is missing the point

“I’m working with Linda on forcing medical schools … to put nutrition into medical school education,” Kennedy said during a cabinet meeting on August 26. The next day, HHS released a statement calling for “increased nutrition education” for medical students. “We can reverse the chronic-disease epidemic simply by changing our diets and lifestyles,” Kennedy said in an accompanying video statement. “But to do that, we need nutrition to be a basic part of every doctor’s training.” It certainly sou

Climate Change Is Bringing Legionnaire’s Disease to a Town Near You

This story originally appeared on Vox and is part of the Climate Desk collaboration. Air conditioners have been working overtime this hot summer, from those tiny window units to the massive AC towers that serve the tightly packed apartment buildings in major cities. And while they bring the relief of cool air, these contraptions also create the conditions for dangerous bacteria to multiply and spread. One particularly nasty bacteria-borne illness is currently spreading in New York City using t

Plague Case Confirmed Near Lake Tahoe After Likely Flea Bite

A California resident has tested positive for the plague after camping near Lake Tahoe, local health officials confirmed. It’s the latest in a string of positive cases in the western U.S. this year. The infected person was likely bitten by a plague-infected flea in the South Lake Tahoe area, according to local health officials. This is the first local case in the area since 2020. The person is currently recovering and is undergoing medical treatment at home. “Plague is naturally present in man

Possible Local Malaria Case Found in New Jersey. Here’s What to Know

A once-vanquished disease spread by mosquitoes may be making inroads into the United States. New Jersey officials are now investigating whether a resident’s malaria infection was locally acquired. The New Jersey Departments of Health (NJDOH) and Environmental Protection reported on the case Monday. The resident hadn’t recently traveled, suggesting they likely caught it from homegrown mosquitoes. If so, this would be the first locally acquired malaria case seen in the state in over three decades

Vitamin E: Health Benefits, Food Sources and What to Know Before Using Supplements

You may have noticed vitamin E on the label of your favorite skin-care products. It's a nutrient that can help protect your skin from UV damage, making it a common ingredient for facial sunscreens. But vitamin E isn't just applied topically -- you also need to get it in your daily diet. Consuming enough vitamin E is crucial because it plays a key role in human development and functioning. The vitamin includes eight compounds, but only one of those -- alpha-tocopherol -- is used in the human body

Travelers Are Unknowingly Smuggling Invasive Ticks Into the U.S.

Here’s an important tip for international travelers coming back home: Be sure to check for any blood-sucking creepy-crawlies attached to you. In a study out today, health experts warn that exotic, potentially disease-carrying ticks are regularly entering the U.S. by hitching a ride onto returning Americans. Tick scientists in Connecticut conducted the research, published Friday in the journal iScience. They detailed seven separate cases of nonnative ticks entering the state via travelers in rec

Woman Diagnosed with Malaria in Washington May Be State’s First Locally Acquired Case

Washington state officials have revealed that a local woman has been diagnosed with malaria, which, if confirmed, would mark the first known case of the disease being acquired in the state. The woman was diagnosed with malaria, a mosquito-borne illness caused by a parasite, on August 2, according to the officials. State and federal public health agencies are working to confirm the source of the infection, according to a statement published on Wednesday. Officials believe that the infection may

Lithium compound can reverse Alzheimer’s in mice: study

“The idea that lithium deficiency could be a cause of Alzheimer’s disease is new and suggests a different therapeutic approach,” said senior author Bruce Yankner, professor of genetics and neurology in the Blavatnik Institute at HMS, who in the 1990s was the first to demonstrate that amyloid beta is toxic. The study raises hopes that researchers could one day use lithium to treat the disease in its entirety rather than focusing on a single facet such as amyloid beta or tau, he said. One of the

NYC Legionnaires’ Disease Outbreak: Cases and Deaths Double, as Officials Pinpoint the Cause

An outbreak of Legionnaires’ disease in NYC has doubled in reported cases and deaths since last week. Officials have struggled to identify the source of the outbreak, but it has now been confirmed. Officials at the NYC Health Department issued the latest update on the outbreak Monday. Fifty-eight people living in Central Harlem have been diagnosed with Legionnaires’ since July 25, while two people have died from it. On the positive side, officials have identified several cooling towers contamin

How Not to Study a Disease (2023)

Image credit: @ionut.stefan.92ish Română In today’s post, I’d like to draw your attention to an absolutely amazing book on the topic of Alzheimer’s disease. Written by Prof. Karl Herrup, professor of neurobiology at the University of Pittsburgh School of Medicine, “How Not to Study a Disease – The Story of Alzheimer’s” takes the reader on a journey of Alzheimer’s research from its inception by Alois Alzheimer to the contemporary understanding of this devastating condition. This is not just an

A Deadly Outbreak of Legionnaires’ Disease Is Hitting NYC

A deadly outbreak of Legionnaires’ disease is ripping through Central Harlem in New York City. Local health officials report that about two dozen residents have been sickened by the pneumonia-causing bacteria so far this month. The NYC Health Department issued its latest update on the outbreak Wednesday, following its first report last week. Since July 25, there have been 22 cases of Legionnaires’ disease diagnosed throughout the area, along with one death. Residents in the affected neighborhoo

What Your Nighttime Breathing Says About Your Health

For decades, sleep disturbance was a punch line: the cartoon dad snoring, the disgruntled partner burying their head under a pillow. But science is beginning to paint a less jovial picture. Sleep apnea—a relatively common disorder where breathing repeatedly stops and starts during sleep—is now being taken seriously as a potential biomarker for a host of major health conditions, from cardiovascular disease to Alzheimer’s, even anxiety and depression. “Sleep is just as important for health as die

There's Neuralink—and There's the Mind-Reading Company That Might Surpass It

Mark Jackson is playing a computer game with his mind. As he reclines in bed, three blue circles appear on a laptop screen a few feet away. One turns red: the target. Jackson is in control of a white circle, which he needs to steer into the target without running into the blue obstacles. The game is a bit like Pac-Man. Except instead of a joystick, Jackson uses his thoughts to control his little white circle. To move left, he thinks about clenching his right fist once. To move right, he thinks a

3D-printed living lung tissue

UBC Okanagan researchers have developed a 3D bio-printed model that closely mimics the complexity of natural lung tissue, an innovation that could transform how scientists study lung disease and develop new treatments. Dr. Emmanuel Osei, Assistant Professor in the Irving K. Barber Faculty of Science, says the model produces tissue that closely resembles the complexity of a human lung, enabling improved testing of respiratory diseases and drug development. “To conduct our research and the testi

Hot Tick Summer Is Here. Here’s What You Need to Know and How to Stay Safe

Summer in the U.S. is now in full swing. That means plenty of outdoor fun, Sun, and, unfortunately, for many of us, tiny eight-legged ticks to avoid. Ticks and the many illnesses they carry, like Lyme disease, are a growing public health threat. Just this week, for instance, the latest data from the Centers for Disease Control and Prevention showed that 2025 so far has seen the highest number of tick-related emergency room visits recorded since 2019. And though the worst tick species are especi

Large-scale DNA study maps 37,000 years of human disease history

A new study suggests that our ancestors’ close cohabitation with domesticated animals and large-scale migrations played a key role in the spread of infectious diseases. The team, led by Professor Eske Willerslev at the Universities of Cambridge and Copenhagen, recovered ancient DNA from 214 known human pathogens in prehistoric humans from Eurasia. They found that the earliest evidence of zoonotic diseases – illnesses transmitted from animals to humans, like COVID in recent times – dates back t

So you wanna build an aging company

Today, aging is cool. In 2024 alone, investors deployed about $8.5B into longevity-focused biotech companies. Aging biotech companies have entered clinical trials. The field has come a long way. But as “aging” (and “longevity”) have become more mainstream, there’s a temptation to stretch the definition to things that don’t belong in the category. Aging is not a single process. It’s a complex interplay of multiple biological processes that, over time, become dysregulated. Understanding it as suc

We’re learning more about what weight-loss drugs do to the body

We know they can suppress appetite, lower blood sugar, and lead to dramatic weight loss. We also know that they come with side effects, which can include nausea, diarrhea, and vomiting. But we are still learning about some of their other effects. On the one hand, these seemingly miraculous drugs appear to improve health in other ways, helping to protect against heart failure, kidney disease, and potentially even substance-use disorders, neurodegenerative diseases, and cancer. But on the other,

Tick Bite? Here's What to Know About Lyme Disease and Your Next Steps

You just finished a satisfying summer hike or wrapped up a weekend of yard work when you spot a tick clinging to your clothes. The fresh-air high fades quickly as you remember the risks -- ticks are known carriers of Lyme disease, a growing concern across the US. Lyme disease cases have more than doubled in recent years, according to the CDC, with annual reports jumping from around 42,000 to nearly 90,000. While part of that increase is due to improved detection and reporting methods, the risk

The United States has lower life expectancy than most similarly wealthy nations

Since taking over as the top US health official in February, Robert F. Kennedy Jr has overseen radical changes that have alarmed many public-health experts. The agency he leads announced that it would cut its workforce by 20,000, and cancelled billions of dollars in federal funding for research and public health. Earlier this month, Kennedy replaced all the members of an influential vaccine advisory committee with hand-picked ones, including some who have expressed scepticism about vaccines. His

After RFK Jr. overhauls CDC panel, measles and flu vaccines are up for debate

With ardent anti-vaccine activist Robert F. Kennedy Jr. in the country's top health position, use of a long-approved vaccine against measles, mumps, rubella, and varicella/chickenpox (MMRV) as well as flu shots that include the preservative thimerosal will now be reevaluated, putting their future availability and use in question. The development seemingly continues to vindicate health experts' worst fears that, as health secretary, Kennedy would attack and dismantle the federal government's scie
