Scientists find that A. echinatior ants have biomineral armour to help them in battle with other ants and protect them from pathogens. 😃
Ants are pretty organised little creatures. Highly social insects, they know how to forage, build complicated nests, steal your pantry snacks, and generally look after the queens and the colony, all by working together.
Leaf-cutter ants turn that cooperation up several notches. Leaf-cutter ant colonies like Acromyrmex echinatior can contain millions of ants, split into four castes that all have different roles to maintain a garden of fungus that the ants eat.
Whole-body positron emission tomography combined with computed tomography (PET/CT) is a cornerstone in the management of lymphoma (cancer in the lymphatic system). PET/CT scans are used to diagnose disease and then to monitor how well patients respond to therapy. However, accurately classifying every single lymph node in a scan as healthy or cancerous is a complex and time-consuming process. Because of this, detailed quantitative treatment monitoring is often not feasible in clinical day-to-day practice.
Researchers at the University of Wisconsin-Madison have recently developed a deep-learning model that can perform this task automatically. This could free up valuable physician time and make quantitative PET/CT treatment monitoring possible for a larger number of patients.
To acquire PET/CT scans, patients are injected with a sugar molecule marked with radioactive fluorine-18 (18 F-fluorodeoxyglucose). When the fluorine atom decays, it emits a positron that instantly annihilates with an electron in its immediate vicinity. This annihilation process emits two back-to-back photons, which the scanner detects and uses to infer the location of the radioactive decay.

We know that spending hour after hour sitting down isn’t good for us, but just how much exercise is needed to counteract the negative health impact of a day at a desk? A new study suggests about 30–40 minutes per day of building up a sweat should do it.
Up to 40 minutes of “moderate to vigorous intensity physical activity” every day is about the right amount to balance out 10 hours of sitting still, the research says – although any amount of exercise or even just standing up helps to some extent.
That’s based on a meta-analysis across nine previous studies, involving a total of 44,370 people in four different countries who were wearing some form of fitness tracker.

The masks are slipping. Police move in on Adamson’s BBQ. blocking access and changing locks to the building, according to CP24, which seems to have been given an exclusive on the story…
Mayor John Tory says the locks have been changed at Adamson Barbecue in Etobicoke on Thursday after the restaurant, for two days straight, defied the province’s lockdown orders that forbid indoor dining.
“I’ve spoken to the police chief this morning … and they have a plan. He’s informed me the locks have been changed on the building … and there’s going to be a police presence there also … it is going to be closed today, you can be sure of that,” Tory tells Breakfast Television.
