How some people maintain weight loss, others don’t

Washington, Sep 16 (ANI): Ever wondered how some people successfully maintain a significant weight loss, while others tend to regain the weight? Well, researchers at The Miriam Hospital attribute such tendencies to a difference in brain activity patterns.

The researchers showed that when individuals who had kept the weight off for several years were shown pictures [...]

Forgotten memories still exist in the brain

Washington, Sept 10 (ANI): A new research by UC Irvine neuroscientists suggests that memories exist even when forgotten.

With the help of advanced brain imaging techniques, the study’s scientists discovered that a person’s brain activity while remembering an event is very similar to when it was first experienced, even if specifics can’t be recalled.

“If the details [...]

MRI methods can show bone marrow stem cells’ viability as brain-repairing therapy

Washington, August 20 (ANI): Researchers at Tel Aviv University have offered new hope for people with incurable neurodegenerative diseases like Huntington’s, Alzheimer’s, and Parkinson’s by showing that the viability of stem cells created from a patient’s own bone marrow can be determined using MRI tracking methods.

Dr. Yoram Cohen, of TAU’s School of Chemistry, claims that [...]

Global 3D map indicates presence of water in certain areas of Earth’s mantle

Washington, August 20 (ANI): Scientists from Oregon State University in the US have created the first global three-dimensional map of electrical conductivity in the Earth’s mantle, which suggests that that enhanced conductivity in certain areas of the mantle may signal the presence of water.

According to scientists, those areas of high conductivity coincide with subduction zones [...]

Washington, August 19 (ANI): Officials of the University of California, San Diego Health Sciences and the Indian Institute of Technology (IIT) Kharagpur have signed a historic preliminary agreement to collaborate in the development of an International Medical Center (IMC) at IIT Kharagpur.

This agreement – [...]

Tone-deaf people lack an important neural pathway

Washington, Aug 19 (ANI): Researchers have found that the nerve fibres that link perception and motor regions of the brain are disconnected in tone-deaf people.

According to experts’ estimates, at least 10 percent of the population may be tone deaf – unable to sing in tune.

The new finding has pinpointed a particular brain circuit that [...]

Worm study provides new model to study invasive cancer

Washington, August 18 (ANI): A single cell’s behaviour during the development of the reproductive tract in the C. elegans worm is providing scientists with significant insights into cancer’s deadly ability to put down roots in new tissues after spreading throughout the body, say researchers.

David Sherwood, a Duke University biologist, has spent several years studying the [...]

Scientists identify lake shorelines on Mars

Washington, August 9(ANI): A team of scientists, using images from the High Resolution Imaging Science Experiment (HiRISE) camera on board NASA’s Mars Reconnaissance Orbiter, have reported direct evidence of lake shorelines in the Shalbatana Vallis in Mars.

Scientists generally believe that warm, wet conditions existed on Mars until only about 3.7 billion years ago.

In recent years, [...]

Why retroviruses like HIV get easily acquainted with uninfected neighbours

Washington, July 28 (ANI): Yale University researchers have found out why retroviruses like HIV can get easily transmitted when they are next to uninfected cells than if they are floating free in the bloodstream.

The researchers, led by Dr. Walther Mothes at Yale, have made movies of viral activity within cells that help explain why cell-to-cell [...]

3-D mapping breakthrough helps docs remove fist-sized tumour from a woman’s brain

Washington, July 15 (ANI): Experts at the University of Cincinnati (UC) have successfully removed a fist-sized tumour from the brain of an Indiana woman, using a technology that involves the fusion of four different types of images into a 3-D map of a patient’s brain.

An eight-member team from the Brain Tumor Center at the [...]

Obesity linked to increased risk of rapid cartilage loss

Washington, July 14 (ANI): A new study has shown that obesity, among other factors, is strongly associated with an increased risk of rapid cartilage loss.

Tibio-femoral cartilage is a flexible connective tissue that covers and protects the bones of the knee. Cartilage damage can occur due to excessive wear and tear, injury, misalignment of the [...]

‘Bullet fingerprinting’ technique improves recovery rate of prints

Washington, July 13 (ANI): A team of scientists has developed ‘Bullet fingerprinting’ technology, which is a simple but effective method to visualize fingerprints even after the print itself has been removed.

The technology has been developed by Dr John Bond, from Northamptonshire Police Scientific Support Unit and an Honorary Research Fellow at the University of Leicester’s [...]

Herschel’s first insight into space reveals spectacular results

Paris, July 11 (ANI): The Herschel Space Observatory has carried out the first test observations with all its instruments, revealing spectacular results, finding water and carbon and revealing dozens of distant galaxies.
