Plant hormone auxin acts as a signalling molecule in embryo development

During the development of organisms, a particular event repeatedly occurs: a signal appears temporarily, but the processes it triggers must be maintained - for example, when the fate of cells in the embryo is established.

Breakdown products of thalidomide cause birth defects: New study

Thalidomide may have been withdrawn in the early 1960s for use by pregnant women, but its dramatic effects remain memorable half a century later. Now, researchers have taken a major step toward understanding exactly how thalidomide causes the birth defects.

Cord blood units treated with signaling molecule show favorable safety profile in long-term animal studies

An innovative experimental treatment for boosting the effectiveness of stem-cell transplants with umbilical cord blood has a favorable safety profile in long-term animal studies, report scientists from Dana-Farber Cancer Institute, Beth Israel Deaconess Medical Center, and Children's Hospital Boston.

A cluttered brain doesn't remember

Lapses in memory occur more frequently with age, yet the reasons for this increasing forgetfulness have not always been clear. According to new research from Concordia University, older individuals have reduced learning and memory because their minds tend to be cluttered with irrelevant information when performing tasks.

Study finds abnormal fetal circulation as a risk factor for fetal thrombotic vasculopathy

Examination of the placenta can offer answers to the questions that arise following an adverse perinatal outcome, such as stillbirth or intrauterine growth restriction. A placental lesion known as fetal thrombotic vasculopathy (FTV) has been associated with a number of adverse outcomes. By studying placentas with this lesion, researchers hope to determine the risks of such serious complications that affect fetuses and newborns.

Gene mutation in Tibetian Terrier dogs causes hereditary form of Parkinson's disease in humans

University of Missouri researchers believe both man and animal will benefit from their discovery that the same gene mutation found in Tibetan Terrier dogs can also be found in a fatal human neurological disorder related to Parkinson's disease.

Spinal fluid analysis can help detect early stage Alzheimer's disease

A new study from the University of Gothenburg, Sweden, shows how analysing spinal fluid can help to detect Alzheimer's disease at an early stage. The researchers behind the study hope that their findings will contribute to a greater international breakthrough for this type of diagnostic method.

Exacerbate-reverse' approach can identify potential therapy for fatal childhood disease

Many genes that cause human diseases have parallel genes in other organisms, including yeast. Now Columbia University researchers have used an innovative yeast-based screening method to identify a possible treatment for the fatal childhood disease Niemann-Pick C.

New biomarker-based test more effective for early acute kidney injury detection

A new biomarker-based diagnostic test is more effective than the current best practice for early detection of adverse outcomes after acute kidney injury, which can be fatal for an estimated 50 percent of the critically ill patients who get the condition.

Study finds more evidence linking high-grade serous ovarian cancer to fallopian tubes

High-grade serous ovarian cancer (HGSOC), the fifth-deadliest cancer among American women, is thought by many scientists to often be a fallopian tube malignancy masquerading as an ovarian one. While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer.
