Scientists identify neurons in mice that, once activated, can change body's metabolic rate, induce hibernation-like state
(Tue, 21 Jan 2025)
A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like
obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut axis.

Reimagining chain mail
(Tue, 21 Jan 2025)
Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM
(for polycatenated architected materials) could have uses in areas ranging from helmets and other protective gear to biomedical devices and robotics.

Can DNA-nanoparticle motors get up to speed with motor proteins?
(Wed, 22 Jan 2025)
DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is
converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism. In this type of movement, the motor is being propelled
by the degradation (or 'burning') of the bonds (or 'bridges') it crosses along the substrate, essentially biasing its motion forward.

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.

Artificial intelligence: Algorithms improve medical image analysis
(Thu, 02 Jan 2025)
Artificial intelligence has the potential to improve the analysis of medical image data. For example, algorithms based on deep learning can determine the location and size of tumors. This is the
result of AutoPET, an international competition in medical image analysis. The seven best autoPET teams report on how algorithms can detect tumor lesions in positron emission tomography (PET) and
computed tomography (CT).
