In a new study published today in Nature Structural and Molecular Biology, scientists from the University of Surrey have uncovered a collection of important proteins that carry out and regulate critical biological processes.
Men with prostate cancer run the risk of brittle bones as a side-effect of their treatment. But one hour's football training a few times a week counters many of the negative effects of the treatment, according to University of Copenhagen scientists.
Results of EORTC trial 26101 presented today at The 20th Annual Scientific Meeting and Education Day of the Society for Neuro-Oncology showed that bevacizumab treatment in patients with progressive glioblastoma, despite prolonged progression-free survival, does not confer a survival advantage.
Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components.

Scientists drilling into the ocean floor have for the first time found out what happens when one tectonic plate first gets pushed under another.
Scientists, engineers and clinicians at the Wyss Institute for Biologically Inspired Engineering at Harvard University and its collaborating institutions, the Beth Israel Deaconess Medical Center (BIDMC) and the University of Massachusetts Medical School (UMMS), have shown in a clinical trial in the BIDMC neonatal intensive care unit (NICU) that their new prevention technology reduces apneic events and improves critical clinical parameters in preterm infants.
More research is needed to better understand polycystic ovary syndrome - one of the leading causes of infertility, according to the Scientific Statement issued by the Endocrine Society.
Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Dead wood has decreased dramatically in the boreal zone due to intensive forest management. Several species dependent on dead wood have suffered from this decline.
When a blunt-force blow injures the spinal cord, the body's immune system can be both friend and foe. Sensing the injury, the immune system dispatches an inflammatory response composed of specialized cells called macrophages to dispose of dead tissue.
The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether the drug combination netupitant/palonosetron (trade name: Akynzeo) offers an added benefit over the appropriate comparator therapy (ACT).
The global population is expected to increase by two to three billion people by 2050, a projection raising serious concerns about sustainable development, biodiversity and food security.
A computer model of tuberculosis has shown that approved treatments prescribing antibiotic doses once or twice a week are more likely to lead to drug resistant strains than are daily antibiotic regimens.
Ground-breaking new research has shown that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.
Meperidine, an opioid analgesic commonly used to control shivering in accidental or therapeutic hypothermia, has been linked to increased seizure risk, but a new study finds little published evidence to support this risk.
Blacklegged ticks (Ixodes scapularis) are the primary vector of Lyme disease to humans, but researchers at Old Dominion University in Virginia are focusing on another tick, Ixodes affinis, even though it doesn't bite people.
A study performed on the NASA Space Shuttle Discovery showed that exposure of mouse embryonic stem cells (mESCs) to microgravity inhibited their ability to differentiate and generate most cell lineages, needed for the development of bone, muscle, the immune system, and other organs and tissues.
There is no substantive evidence for a 'pause' or 'hiatus' in global warming and the use of those terms is therefore inaccurate, new research from the University of Bristol, UK has found.
Researchers for the first time have attempted to measure all the material leaving and entering a mountain range over millions of years and discovered that glacial erosion can, under the right circumstances, wear down mountains faster than plate tectonics can build them.
The intensity of Earth's geomagnetic field has been dropping for the past 200 years, at a rate that some scientists suspect may cause the field to bottom out in 2,000 years, temporarily leaving the planet unprotected against damaging charged particles from the sun.
What is true for double-blade razors is also true for solar cells: two work steps are more thorough than one.
New Johns Hopkins Bloomberg School of Public Health-led research finds that blood taken from children up to the age of five contains molecular evidence about whether their mothers smoked during pregnancy.
When a high-fat diet causes us to become obese, it also appears to prompt normally bustling immune cells in our brain to become sedentary and start consuming the connections between our neurons, scientists say.
University of Notre Dame researchers have discovered a compound that accelerates diabetic wound healing, which may open the door to new treatment strategies.

Scientists from the University of Exeter are warning of the risks that seismic surveys may pose to sea turtles. Widely used in marine oil and gas exploration, seismic surveys use airguns to produce sound waves that penetrate the sea floor to map oil and gas reserves.
A Michigan State University study has found that too much of a hormone commonly used during in vitro fertility, or IVF, treatments actually decreases a woman's chances of having a baby.
