Forgetting requires more Conscious Effort than Remembering, Study Finds

Despite the decades of research on the brain‘s ability to voluntarily discard certain memories, scientists are still trying to pin down the mechanism behind it, which could eventually allow mental health professionals to offer their patients the option of getting rid of memories which trigger involuntary, maladaptive responses. Now, a […]

Scientists identify genetic factors that may cause some people to become obese

Obesity is a major public-health problem in the United States and around the world, with an estimated 650 million people suffering from the condition. One of the biggest challenges of this ever-worsening condition is figuring out why people become obese in the first place, and why some people are more […]

New optical imaging system could be deployed to find tiny tumors

Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named “DOLPHIN,” which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body. In a new […]

New CRISPR technique for studying gene function developed

When researchers want to understand a gene’s function, they silence or disable that gene in a model organism, such as a fruit fly, and then look for unusual effects on the fly. This is referred to as creating loss-of-function, or “knocking out” a gene. A study published in the journal […]

Researchers find high blood pressure link

Early onset menstruation linked to high blood pressure in late adulthood, UGA study finds. The age a woman begins menstruation is associated with having high blood pressure later in her life, according to a team of researchers at the University of Georgia. Specifically, researchers found that early onset menstruation significantly increased […]

Pregnancy infection increases a child’s autism, suicide risk

Children whose mothers were hospitalized with an infection during pregnancy may be at increased risk for autism, depression and suicide later in life, according to a new study by researchers at the University of Washington School of Medicine in Seattle, Washington, and the Sahlgrenska Academy in Gothenburg, Sweden. Previous research […]

Embryos’ signals take multiple paths

Rice University scientists have found significant differences between the methods signaling pathways use to prompt cells to differentiate – that is, whether to become organs, bone, blood vessels, nerves or skin. Rice bioscientist Aryeh Warmflash and alumnus Idse Heemskerk led a team that discovered stem cells are sensitive not only to the signals that […]

‘Game changer’ in treatment of chronic lymphocytic leukaemia

The Cardiff researchers say that the test could now be a ‘game changer’ in the treatment of chronic lymphocytic leukaemia (CLL). It also has the potential to change how other cancers, including myeloma and breast cancer, are treated. While previous versions of the test had taken a week to process, […]

Diet reverses Alzheimer’s-like symptoms in lab model

A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say. Researchers emphasize that the study, published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings […]
