3T MRI leads to better diagnosis for focal epilepsy

A recent study found that 3T MRI is better at detecting and characterizing structural brain abnormalities in patients with focal epilepsy than 1.5T MRI, leading to a better diagnosis and safer treatment options. This improvement was seen in the detection of lesions and accurate characterization of abnormalities.

Changes in urine could lead to BSE test for live animals

Scientists have identified biomarkers in cattle urine that can indicate the presence and progression of Bovine Spongiform Encephalopathy disease. This discovery may lead to a urine-based test for detecting BSE in live animals, allowing for alternative surveillance procedures and improving breeding stock health.

How STDs increase the risk of becoming infected with HIV

Research suggests that sexually transmitted diseases (STDs) can increase the risk of contracting HIV by activating Langerhans cells in the skin and vagina. This activation allows the virus to spread more easily, highlighting the potential for anti-inflammatory treatments to prevent HIV transmission.

Nutritionists of the UGR suggest diet improvements during Ramadan

Researchers from the University of Granada found that university students following Ramadan experience macronutrient imbalances, leading to increased corporal fat and reduced muscular mass. A new diet plan has been proposed to counterbalance these effects by reducing fat and increasing protein and carbohydrate intake.

How memories are made, and recalled

Scientists at UCLA and the Weizmann Institute of Science recorded individual brain cells as they recalled memories from epilepsy patients' brains. The study confirms that spontaneous memories arise with activity of the same neurons that were recorded as they fired when the memory was first being made.

Molecular evolution is echoed in bat ears

Research by Queen Mary University of London scientists found that some bat species' echolocation genes are similar to those of fruit bats, indicating possible independent evolution of the trait. This suggests that echolocation may not be a single evolutionary event but rather an example of convergent evolution.
