Low-oxygen conditions spur growth of breast cancer stem cells

Working with human breast cancer cells and mice, scientists at The Johns Hopkins University say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.

TSRI scientists develop new process to synthesize naturally occurring compound phorbol

In a landmark feat of chemical synthesis, scientists at The Scripps Research Institute have developed a 19-step process for making the naturally occurring compound phorbol in the laboratory, in quantities that are useful for pharmaceutical research.

High-intensity workout could do more harm than good

High-intensity 'sprint training' may be gaining popularity at gyms, but if you're new to this form of exercise, the workout could do more harm than good.

Wide-field imaging approach can help study underlying mechanisms of brain function

University of Oregon scientists have looked into the brains of living mice to see in real time the processing of sensory information and generation of behavioral responses.

Novel mechanism can suppress blood vessel leakage, reduce tumour spread in mice

Cancer therapy is often hampered by the accumulation of fluids in and around the tumour, which is caused by leakage from the blood vessels in the tumour. Researchers at Uppsala University now show how leakage from blood vessels is regulated.

German scientists analyse LOV proteins using neutron scattering

The internal movements of proteins can be important for their functionality; researchers are discovering more and more examples of this. Now, with the aid of neutron spectroscopy, dynamic processes have also been detected in so-called "LOV photoreceptors" by scientists from Jülich, Aachen, Dusseldorf and Garching near Munich.

Long-term recreational football training improves health of older men

A new scientific study shows that long-term recreational football training produces a number of marked improvements in health profile for 63-75 year old untrained men -- including a reduced risk of developing cardiovascular diseases and diabetes.

Laser light could be used to measure oxygen supply in premature babies' lungs

Premature babies have a hard time getting the oxygen they need as their lungs are not sufficiently developed. Today you can only use X-rays to see how much air babies' lungs contain, but, according to research from Lund University in Sweden, in the future, these types of tests could be done using laser light.

Researchers disprove previously assumed behavior of macrophage immune cells

What happens when macrophage immune cells are activated in the course of an inflammation to combat pathogens such as bacteria or viruses? Researchers of the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg pursued this very question. The researchers discovered that the immune cells behave differently from what was previously assumed. Their metabolism upholds the production of antimicrobial substances and fatty acids during activation. In this way, they deliver important resources for the immune responses they trigger.

Women's stress hormone levels before pregnancy may predict lower-birthweight baby

Before women even become pregnant, their biological profile may predict a lower-birthweight baby, a UCLA-led research team reports.

Sodium MRI could provide more detailed picture of tissue health and disease

MRI experts at The University of Nottingham win £1m grant to adapt scanning techniques to pick up sodium in the body. The research could lead to much more detailed MRI scans in the future with significant improvements to the diagnosis and treatment of many diseases.

Mothers give offspring a head start in life

Thank your mothers: A research collaboration between UC Santa Barbara and L'École Normale Supérieure in Paris has proven that deterministic maternal effects can give offspring a better start on life.

Global improvement in antioxidant capacity may delay ageing

The gradual accumulation of cell damage plays a very important role in the origin of ageing. There are many sources of cellular damage, however, which ones are really responsible for ageing and which ones are inconsequential for ageing is a question that still lacks an answer

Researchers provide new mechanism for age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause of visual impairment in people over 50 in developed countries. Although this condition affects up to 20% of people between the ages of 65 and 75, what drives abnormal blood vessels to invade the retina is unknown.

Drugs to help energy-starved photoreceptors offers new avenue for treating AMD , MacTel

New research from Boston Children's Hospital could potentially change how doctors approach two blinding diseases: 'Wet' age-related macular degeneration (AMD), the leading cause of blindness in the elderly, and macular telangiectasia (MacTel).

Advances in new scanning technology may provide a clearer picture of lung disease

New scanning technology which will give a much clearer picture of lung disease has taken a major step forward thanks to scientists at The University of Nottingham.

Findings offer novel way for creating drugs to stop mitochondria from destroying cells during stress

Malfunctioning mitochondria — the power plants in cells — are behind the damage caused by strokes, heart attacks, and neurodegenerative diseases, but little has been known about how to stop these reactors from melting down, destroying cells and tissue. Mitochondria also take up calcium, which regulates energy production.
