Cannabis during pregnancy bumps psychosis risk in offspring

Pregnant women who use cannabis may slightly increase the risk their unborn child will develop psychosis later in life, suggests new research from Washington University in St. Louis. “Our research shows that prenatal marijuana exposure after maternal knowledge of pregnancy is associated with a small increase in psychosis proneness during […]

Study in mice examines impact of reused cooking oil on breast cancer progression

A new study in mice suggests that consuming the chemical compounds found in thermally abused cooking oil may trigger genetic changes that promote the progression of late-stage breast cancer. Thermally abused frying oil – cooking oil that has been repeatedly reheated to high temperatures – may act as a toxicological […]

Lab grown "brains" successfully model disease

The human brain is one of the most complex organs. Its complexity challenges our ability to study its structure and function. As a result, many brain-related diseases are not fully understood and adequate treatments are often lacking. Scientists from Max Planck Institute of Psychiatry were able to model a developmental […]

Obesity and emotional problems develop together as children age, study shows

High BMI and mental ill-health go increasingly hand-in-hand to present a combined health risk for children from mid-childhood, according to a new study. Researchers from the University of Liverpool and University College London analysed data on more than 17,000 children born across the UK in 2000-01, who are taking part […]

Tumor-Associated Immune Cells Hinder Frontline Chemotherapy Drug in Pancreatic Cancer

A frontline chemotherapy drug given to patients with pancreatic cancer is made less effective because similar compounds released by tumor-associated immune cells block the drug’s action, research led by the University of Michigan Rogel Cancer Center found.The chemotherapy drug gemcitabine is an anti-metabolite. It’s similar to normal metabolites taken up by the […]

New Study Identifies Causative Genes in Osteoporosis

Researchers identified two novel genes that affect bone-formation cells relevant to fractures and osteoporosis; understanding these genes could lead to more effective treatments. Examining a person’s DNA can help scientists understand if the individual is at risk for osteoporosis, the chronic bone-weakening condition that affects millions of Americans. In a […]

Exercising is good for your brain, but how?

Physical exercise is good for you. You already know that and if you are not exercising is just because you are too lazy. However, it is still quite strange that exercising is not only good for your body, but for your brain as well. How? An international team from The […]

Scientists uncover genetic reasons why many Border Collies go blind

Border Collies are considered to be one of the smartest breeds of dogs on Earth. They are fun, playful and easy to train. However, some of them suffer from various health conditions. For example, a condition called goniodysgenesis or gonio causes sudden blindness. Now scientists from the University of Edinburgh […]

Discovery of self-destruct mechanism in algae could have broad applications for antibiotics and biofuels

In a discovery that could have broad applications from the development of targeted antibiotics to the production of biofuels in industry, University of Alberta biologists discovered evidence of bacteria causing apoptosis, or programmed cell death, in algae. “It sounds odd, but programmed cell death is important to all large organisms.

Developing a blood test to screen for ovarian cancer

More than 16,000 women die from ovarian cancer each year in the United States. Ovarian cancer is often called the “silent killer” because the symptoms are so vague that women are often not diagnosed with ovarian cancer until the disease has progressed to advanced stages. Currently, no blood test exists […]
