Researchers raise alarm over threat to Mexican fireflies
Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species
Photinus palaciosi
. Endemic to Mexico’s Tlaxcala forests,
P. palaciosi
is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

Doctors have long considered the thymus expendable. But could removing it be fatal?
The thymus, a butterfly-shaped organ that sits between our collarbones, has never seemed like a particularly useful appendage—at least in adults. During early childhood, it provides a place for T cells (the T stands for thymus) to mature into immune cells that attack invaders. But during adolescence the organ begins to shrink and mostly stops producing these cells. By adulthood, it’s assumed to be so useless that cardiac surgeons will occasionally remove it just to get easier access to the heart.
But researchers have recently started to question that assumption, and a study published today in
The New England Jo...

‘It’s one of the great mysteries of our time’: why extreme food allergies are on the rise – and what we can do about them
More and more youngsters are experiencing serious reactions to everyday foods – and even our pets are suffering. We meet one family who lost a son to anaphylaxis and ask what can be doneWhen five-year-old Benedict Blythe woke up on the morning of 1 December 2021, he was excited that Christmas was coming. He came downstairs to open the first box in his Advent calendar containing a plastic springy frog and a dairy-free white chocolate (Benedict was allergic to milk, along with many other foods including soy, sesame, eggs and nuts). It was Benedict ’s first term at school – Barnack primary in Stamford – and he loved i...

Allergy season really is getting worse every year. Here ’s how science can help | Theresa MacPhail
We are slowly beginning to understand how our immune systems work, which will help us prevent allergies – but more research is desperately neededIf it seems as though everyone around you has been sneezing, coughing and wheezing more often this summer, you ’re not imagining things. Allergies are both becoming more common and getting worse. In some ways, this is not news. Respiratory allergy, asthma, eczema and food allergy rates have all been ticking upward for at least the past 50 years.

It needs more than a pollen forecast to ease the proliferation of allergies | Tim Adams
Changes in our lifestyles, from diet to washing habits, and in the world surrounding us, may explain why so many are strugglingThe Met Office offers a daily pollen guide, in tones not unlike the storm warning of the shipping forecast: poetic for those not affected, alarming if you are facing a force 8.Saturday ’sreads: “The grass pollen risk is on the rise, as more grasses come into flower.

Why are food allergies on the rise and is a cure on the horizon? – podcast
Food allergies appear to be increasing globally, but as scientific understanding improves, some experts believe we may one day be able to eliminate them altogether. Ian Sample speaks to Dr Kari Nadeau, an allergy specialist at Harvard School of Public Health and author of the book The End of Food Allergy, to discuss why food allergies are on the rise and what we can do to prevent – and possibly even cure – themContinue reading...

Cats, peanuts, bee stings … the irritating truth about allergies
More and more of us suffer from allergies, and medicine is struggling to keep up. Rebecca Seal talks to medical anthropologist Theresa MacPhailWhen Theresa MacPhail was four, her brother was killed in an accident. When she was 14, her mother died in a car crash. And when she was 24, her father died from anaphylactic shock after a bee flew in through the open window of his truck and stung him in the neck. For anyone else, these devastating experiences would almost certainly have been psychologically catastrophic. “I have several friends who are psychology professors, and they’re always saying, ‘No offence but, by righ...

Bio-Tribocorrosion of Titanium Dental Implants and Its Toxicological Implications: A Scoping Review
ScientificWorldJournal. 2022 Oct 21;2022:4498613. doi: 10.1155/2022/4498613. eCollection 2022.ABSTRACTBio-tribocorrosion is a phenomenon that combines the essentials of tribology (friction, wear, and lubrication) and corrosion with microbiological processes. Lately, it has gained attention in implant dentistry because dental implants are exposed to wear, friction, and biofilm formation in the corrosive oral environment. They may degrade upon exposure to various microbial, biochemical, and electrochemical factors in the oral cavity. The mechanical movement of the implant components produces friction and wear that facilitate...
