What happens when a zoo animal gets sick? For most of the history of zoos, that question had an answer most visitors never saw. Now, one of the world's oldest zoological societies is building a facility designed to change that — and what they're planning goes well beyond routine checkups.
The Zoological Society of London is constructing a new wildlife health center that will allow visitors to observe animals receiving medical care firsthand. Some of what they'll see will be routine — weight checks, dental exams, the kind of maintenance that keeps zoo populations healthy. But onlookers may also get a window into surgical procedures, and in some cases, postmortems. It's an unusually transparent approach for an institution that has traditionally kept its medical operations behind closed doors.
Not everyone is convinced. Critics argue the center is more about capitalizing on public curiosity than genuinely benefiting the animals in its care — that making medicine into a spectator sport serves the zoo's revenue more than its residents.
ZSL pushes back on that framing. The center is designed to be more than an exhibit. It's intended to function as a global training resource for wildlife vets, a hub where expertise in animal medicine can be developed and shared across institutions worldwide. The argument is that visibility and conservation aren't in conflict — that showing people what it actually takes to keep wild animals healthy is exactly the kind of thing that builds the public understanding zoos increasingly depend on to justify their existence.
The deeper question the center raises isn't really about one zoo or one building. It's about what zoos are actually for — and whether letting people watch is a compromise of that mission or an extension of it.
Did you put on sunscreen today? Yes? Go put on some more.
Tans may be fashionable, but the risks that come with sun damage are anything but — and they can last a lifetime. That's why England banned tanning beds for anyone under 18 back in 2011. Even so, people as young as 14 have found ways to use them illegally. Now, the rules are getting stricter: businesses will be legally required to check ID before letting anyone near a sunbed, and salons will need to post clear health warnings — including dropping any misleading claims that certain beds can prevent sunburn or help with weight loss.
Even with stronger laws, misinformation is still a problem. Rumors about tanning beds offering benefits like vitamin D have a way of spreading while the risks get quietly ignored. Experts say that even a single tanning bed session before the age of 35 increases the risk of skin cancer by nearly 60% — and young skin is especially vulnerable. Skin cancer is already the most common cancer in the world. The tan isn't worth it.
The Democratic Republic of the Congo (DRC) is months into a serious Ebola outbreak caused by the Bundibugyo species of the virus. Its rapid spread has prompted health officials to raise the risk assessment to "very high" nationally, "high" regionally, and "low" globally. The Bundibugyo species has a case fatality rate of about one in three people, and there's currently no approved vaccine for this type of Ebola. Scientists at the University of Oxford are racing to develop one, using a strategy that may sound familiar.
During the COVID-19 pandemic, scientists were able to develop vaccines quickly by using a harmless virus to deliver genetic material from the coronavirus. It may sound like the world’s worst Amazon delivery, but that material acts as instructions to teach the immune system what to recognize, so it can fight the real virus if a person is exposed later. It’s like showing your immune system a "wanted poster" of a criminal, and giving your body time to figure out how to respond if faced with the actual criminal.
Now, scientists are using the same strategy for Ebola: a harmless virus delivers genetic instructions from the Bundibugyo Ebola virus, helping the immune system prepare without causing the disease itself. Health officials hope the outbreak can be contained without a vaccine, but because Ebola can spread quickly and cause severe illness, having a vaccine ready would provide another powerful tool to help stop it — a definite case of "better safe than sorry."
Cholesterol is tricky — your body needs the waxy substance to build cells and make hormones, but there’s a bad type of cholesterol called “LDL” (low-density lipoprotein). Too much LDL can put people at risk for heart attacks or stroke, so controlling cholesterol levels can be life-saving.
Luckily, a new gene editing therapy called VERVE-102 may be able to help with high cholesterol. There’s a trial running now that’s small but mighty, involving only 35 patients, all of whom have either inherited high cholesterol or have had a heart attack at a young age. They continued their regular medication but added this new gene editing therapy to their treatment.
Not only did results show levels of bad cholesterol reduced by up to 62%, but the level continued to remain low after a year, suggesting that patients may only need one treatment to feel the effects of this treatment for the rest of their lives. Is it magic? Close! It’s science!
The idea behind the gene editing plays off of the liver’s role. It’s supposed to clear bad cholesterol from the blood and stop it from clogging up vessels, unless a protein called PCSK9 gets in the way. PCSK9! It even kind of sounds like “pesky”! The new medicine edits PCSK9’s gene, so that it stays out of the way and the liver can do its job.
Chemotherapy works. It also takes a serious toll — on energy, on the immune system, on everyday quality of life. For decades, that trade-off has been treated as unavoidable. A new drug being used to treat ovarian cancer suggests it might not have to be.
The treatment works by attaching a chemotherapy drug to an antibody — a protein the body uses naturally to identify and target specific cells. When the drug enters the body, the antibodies seek out cancer cells specifically, binding to them and leaving healthy tissue alone. Once inside the cancer cell, the antibody breaks down and releases the chemotherapy drug, destroying the cancer from within. The rest of the body barely notices.
For patients like Patricia Hill, the difference has been significant. After multiple rounds of conventional chemotherapy in the 3 years since her ovarian cancer diagnosis, she describes finally feeling well enough to socialize and enjoy daily life again. That shift — from surviving treatment to actually living alongside it — is what researchers have spent decades working toward.
The drug is still being studied, but early results point in two directions that matter: better quality of life during treatment, and the possibility of longer survival afterward. Those two things don't always come together in cancer research. When they do, it tends to mean something genuinely new is happening.
The DRC (Democratic Republic of the Congo) is a large central African country now facing an Ebola outbreak along with neighboring Uganda. Ebola is a serious virus spread through contact with infected blood or body fluids, causing fever, vomiting, and bleeding. This outbreak's strain has no approved vaccine or treatment.
This isn't the DRC's first health crisis — and it's not bad luck. Three main factors are at play: the DRC borders nine countries with heavy cross-border movement and conflict-driven displacement, making disease spread easy; its health system is stretched thin, so early symptoms (which mimic other illnesses) often go unnoticed; and close contact with wildlife in its vast forests — including hunting and eating bushmeat — raises the risk of animal-to-human disease jumps.
Together, these factors explain why outbreaks keep happening — and why this one deserves close attention.
Don’t you hate it when you’re late for work, but you just can’t find your bone and lunch bag of kibble? That may be the case for a group of dogs in Gulu, Northern Uganda, who work as therapy dogs, helping people with tough upbringings navigate their trauma and adjust to a happy life. To support a population that grew up in a war (and the unsafe conditions that came with it), a charity has paired them with dogs.
What’s better? The dogs benefit, too! We’re not talking about an end-of-the-week paycheck or big office parties, but something better: overdue love and affection. All the dogs are former street dogs, so they weren’t properly cared for, and these have helped more than 120 people and dogs find healing bonds with each other.
Beekeeper Nick was confused when his bees kept dying off. He kept his hives being stocked with food, so why did he still lose around 75% of the colony? The answer was in what was (or wasn’t) in his bees’ food.
In the wild, bees take what they need from flowers to make honey, and then feed off this honey in the winter. When we take this honey for ourselves, beekeepers replace it with supplementary food in the form of sugar and water, and scientists now say that bees can’t subsist off of just sugar and water, as the simple combination was missing key nutrients. Your parents probably said the same thing about why you can’t just have cake for dinner!
After years of testing different foods for bees, scientists have finally discovered how to make the core ingredient, called “sterole.” Oxford scientists have been developing the best foods for bees, and have found that the bees who consumed the food with sterole were healthier, and had up to 15 times more baby bees! This breakthrough is incredibly important — it means bees can still thrive without floral pollen, which would also help our food security, since bees are so important for pollinating crops.
