TRPC1 protein responds to weak magnetic fields to promote muscle health, shows study

As people age, they progressively lose muscle mass and strength, and this can lead to frailty and other age-related diseases. As the causes for the decline remain largely unknown, promoting muscle health is an area of great research interest.

Study on SARS-Cov2 genome may prepare scientists for future ‘SARS-CoV3’ viruses

The genetic code of the SARS-CoV2 virus is exactly 29,902 characters long, strung through a long RNA molecule. It contains information for the production of 27 proteins.

Scientists reveal new evidence of electrical pathway in the heart

These days having both a land line and a mobile phone seems like overkill. But Virginia Tech researchers have shown that the heart relies on at least two key communication channels to keep abnormal heart rhythms in check.

White blood cells can be used to attack tumors after completing a special training

Scientists at the National Center for Tumor Diseases Dresden and Dresden University Medicine, together with an international team of researchers, were able to demonstrate that certain white blood cells, so-called neutrophil granulocytes, can potentially - after completing a special training program - be utilized for the treatment of tumors.

Physicists find way to circumvent an old theory to cancel magnetic fields remotely

A team of scientists including two physicists at the University of Sussex has found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance.

New method makes the superficial white matter visible in the living human brain

Traditionally, neuroscience regards the brain as being made up of two basic tissue types. Billions of neurons make up the grey matter, forming a thin layer on the brain's surface.

Hydrogels and magnetic field could be used to rebuild complex body tissues

Using a magnetic field and hydrogels, a team of researchers in the Perelman School of Medicine at the University of Pennsylvania have demonstrated a new possible way to rebuild complex body tissues, which could result in more lasting fixes to common injuries, such as cartilage degeneration.

A new method for imaging-guided synergistic cancer therapy

A joint research team led by Prof. WANG Hui and Prof. LIN Wenchu from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science developed a synthesis of metal-free multifunctional therapeutic reagents, called graphitic carbon nitride quantum dots embedded in carbon nanosheets (CNQD-CN), via a one-step hydrothermal treatment.

Portable, low-field MRI device can be safely used at patient bedside, shows study

A portable, low-field magnetic resonance imaging (MRI) device can be safely used at bedside in complex clinical care settings to evaluate critically-ill patients for suspected stroke, traumatic brain injury (TBI), or other neurological problems, results of a proof-of-concept study show.
