Life cycles of some insects adapt well to a changing climate: Others, not so much
(Sat, 01 Feb 2025)
Some biologists speculate that animals will get smaller with global warming to reduce heat stress. While this may be true of warm-blooded animals, what about exotherms like insects? Thanks to a
65-year-old grasshopper collection, scientists have documented that some species -- those overwintering as juveniles -- got larger over the years, helped by an earlier green spring. Grasshoppers with
other lifestyles got smaller. Much of this can be predicted given what biologists know of insect life cycles.

'Altar tent' discovery puts Islamic art at the heart of medieval Christianity
(Sat, 01 Feb 2025)
A 13th-century fresco rediscovered in Ferrara, Italy, provides unique evidence of medieval churches using Islamic tents to conceal their high altars. The 700-year-old fresco is thought to be the only
surviving image of its kind, offering precious evidence of a little-known Christian practice.

New research unlocks key to long-lasting immune response in cancer and chronic diseases
(Sat, 01 Feb 2025)
Prolonged illnesses like cancer and chronic infections often leave the immune system in a state of exhaustion, where its frontline defenders -- T cells -- lose their ability to function effectively.
Researchers have identified a rare type of immune cells, called stem-like T cells, that holds the key to maintaining powerful, long-term immune responses.

PET probe images inflammation with high sensitivity and selectivity
(Wed, 22 Jan 2025)
Researchers have developed a breakthrough method to detect inflammation in the body using positron emission tomography (PET) imaging. This innovative probe targets CD45, a marker abundantly expressed
on all immune cells but absent from other cell types.

Ultrasound-directed microbubbles could boost immune response against tumors
(Wed, 15 Jan 2025)
Researchers have designed process that uses ultrasound to modify the behavior of cancer-fighting T cells by increasing their cell permeability. They targeted freshly isolated human immune cells with
tightly focused ultrasound beams and clinically approved contrast agent microbubbles. When hit with the ultrasound, the bubbles vibrate at extremely high frequency, acting as a push-pull on the walls
of the T cell's membranes. This can mimic the T cell's natural response to the presence of an antigen. The T cell then begins to secrete vital signalling molecules that would otherwise be restricted
by the tumor's hostile microenvironment. The process does not damage the cell itself.

MRI scanning and biopsy could reduce delays in the correct treatment for bladder cancer by more than six weeks
(Wed, 15 Jan 2025)
Patients with a common aggressive type of bladder cancer could get correct treatment significantly quicker as new research suggests that initial MRI imaging and biopsy could be used to reduce the
time patients wait.
