Researchers have found a possible biological reason why people with diabetes are prone to depression.

Microenvironment of hematopoietic stem cells can be a target for myeloproliferative disorders
The protective microenvironment of the hematopoietic stem cell niche, which produces cells of the blood and the immune system, also protects against myeloproliferative neoplasia.

Molecular footballs could revolutionize your next World Cup experience!
A new way to assemble individual molecules could revolutionize the creation of novel materials with numerous potential applications, including emerging technologies such as flexible TVs.

The brain's balancing act
Researchers at the University of California, San Diego School of Medicine have discovered a fundamental mechanism by which the brain maintains its internal balance.

Nutritional sports supplements sold in Australia test positive for banned androgens
Some nutritional sports supplements marketed to athletes -- claiming to help them build lean muscle, reduce body fat and enhance endurance -- are secretly fortified with androgens, which are banned from use in sports, a new study from Australia finds.

Low number of taste buds linked to older age, higher fasting blood sugar
A study finds that the number of taste buds we have on our tongue decreases as we get older, and that the lower the number of taste buds, the more likely for fasting blood glucose (sugar) levels to be higher than normal.

Mysterious 'Magic Island' appears on Saturn moon
Astronomers have discovered a bright, mysterious geologic object -- where one never existed -- on Cassini mission radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan.

Protons power protein portal to push zinc out of cells
Researchers at The Johns Hopkins University report they have deciphered the inner workings of a protein called YiiP that prevents the lethal buildup of zinc inside bacteria.

The ICEMAN study -- How keeping cool could spur metabolic benefits
A new study being presented today at ICE/ENDO 2014, the joint meeting of the International Society of Endocrinology and the Endocrine Society in Chicago, demonstrates that ambient temperatures can influence the growth or loss of brown fat in people.

Testosterone replacement may help older men improve and maintain aerobic capacity
Testosterone replacement therapy may help older men who have limited mobility and low testosterone improve their aerobic capacity and lessen its decline with age, new research finds.

Soy supplements appear to be safe, beneficial in diabetic men
Soy protein supplements, which contain natural estrogens, do not reduce testosterone levels in men with type 2 diabetes who already have borderline-low testosterone, according to a new study.

Low testosterone raises risk of age-related functional disability
Elderly men with low levels of testosterone or other sex hormones have twice the likelihood of having declining physical function over two years' time compared with their peers who have the highest hormone levels, a new study from Australia finds.

BPA exposure during fetal development raises risk of precancerous prostate lesions
A new study has found for the first time that the endocrine-disrupting chemical bisphenol A, BPA, reprograms the developing prostate, making the gland more susceptible to precancerous lesions and other diseases later in a man's life.

Family of proteins plays key role in cellular pump dynamics
Case Western Reserve University scientists have discovered how a family of proteins -- cation diffusion facilitators -- regulates an important cellular cycle where a cell's energy generated is converted to necessary cellular functions.

Exercising first, dieting later protects patients with metabolic syndrome from muscle loss
Younger and older women tend to lose lean muscle mass, along with fat, unless they engage in physical activity before they attempt weight loss, a new study from Israel finds.

Cancer by remote-control
One of the deadliest forms of paediatric brain tumour, Group 3 medulloblastoma, is linked to a variety of large-scale DNA rearrangements which all have the same overall effect on specific genes located on different chromosomes.

Exposure to fungicide, tolyfluanid, disrupts energy metabolism
Mice exposed to the fungicide tolyfluanid showed metabolic changes similar to those that signify the development of the metabolic syndrome.

Growth hormone defect may protect against diabetes, cancer in unique ecuador population
People who lack growth hormone receptors also appear to have marked insulin sensitivity that prevents them from developing diabetes and lowers their risk for cancer, despite their increased percentage of body fat, new research finds.

Hypothyroidism may lead to impaired driving
People with significant hypothyroidism can experience impaired driving similar to those who are driving when intoxicated by alcohol, a new study finds.

Architecture of signaling proteins enhances knowledge of key receptors
A team of scientists from Duke Medicine, the University of Michigan and Stanford University has determined the underlying architecture of a cellular signaling complex involved in the body's response to stimuli such as light and pain.

Denosumab treatment for postmenopausal osteoporosis increases bone density
Postmenopausal women with osteoporosis who take denosumab long-term have increased bone density, sustained low rate of fractures, and a favorable benefit/risk profile, a new multinational study finds.

Vitamin D can lower weight, blood sugar via the brain
Vitamin D treatment acts in the brain to improve weight and blood glucose (sugar) control in obese rats, according to a new study being presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago.

Gestational diabetes is associated with declining cognitive function
Women who develop diabetes during pregnancy, called gestational diabetes, perform worse on cognitive function tests than do women with a normal pregnancy, according to a new study from Turkey.

Regional weather extremes linked to atmospheric variations
Variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions, a new study has shown.

Empagliflozin lowers high blood pressure and blood sugar in diabetics
An investigational drug to treat type 2 diabetes, empagliflozin, lowers blood pressure in patients with type 2 diabetes and hypertension -- high blood pressure -- a new study finds.

University scientists unraveling nature of Higgs boson
Physics research finds that Higgs bosons decay into fermions, which gives elementary particles mass.

The Lancet: Midwifery matters 'more than ever'
Midwifery has a crucial part to play in saving the lives of millions of women and children who die during and around the time of pregnancy, according to a major new Series, published in The Lancet.

Biologists find 'missing link' in the production of protein factories in cells
Biologists at UC San Diego have found the 'missing link' in the chemical system that enables animal cells to produce ribosomes -- the thousands of protein 'factories' contained within each cell that manufacture all of the proteins needed to build tissue and sustain life.

Evidence found for the Higgs boson direct decay into fermions
For the first time, researchers at CERN have found evidence for the direct decay of the Higgs boson into fermions -- another strong indication that the particle discovered in 2012 behaves in the way the standard model of particle physics predicts.

Most people with type 1 diabetes do not use diabetes devices to get long-term data
Almost 70 percent of adults with type 1 diabetes never use their blood glucose self-monitoring devices or insulin pumps to download historical data about their blood sugar levels and insulin doses.

Study shows greater potential for solar power
Concentrating solar power could supply a large fraction of the power supply in a decarbonized energy system, shows a new study of the technology and its potential practical application.

Researchers discover new genes that promote brain cancer
Study identifies two novel oncogenes that cause childhood brain cancer when activated.

Long-term mild cold exposure can stimulate brown fat growth and activity in humans and may benefit glucose and energy metabolism, a new study finds.

Unlocking milk's formula could save lives, say scientists
A new study on the digestion of milk could lead to the development of new formulas for premature babies, weight loss drinks and potentially new drug delivery systems.
