Meditation eases anxiety, fatigue and pain for women undergoing breast cancer biopsies, according to researchers. They also found that music is effective, but to a lesser extent.
African-American patients with connective tissue diseases such as lupus or rheumatoid arthritis are twice as likely as white patients to suffer from atherosclerotic blood vessels, which increase the risk of a heart attack, stroke or death.
A process has been uncovered by researchers that uses pressure to deliver chemical probes in a fine-tuned manner into living cells.
The key to an inherited deficiency, predisposing people to emphysema and other lung conditions, could lie in their Viking roots. Archaeological excavations of Viking latrine pits in Denmark have revealed that these populations suffered massive worm infestations. The way that their genes developed to protect their vital organs from disease caused by worms has become the inherited trait which can now lead to lung disease in smokers.
The lack of an evidence base in the donor-funded response to Syrian migrant crisis means funds may be allocated to ineffective interventions, say researchers, who call on funders and policymakers in London for this week's Syrian Donor Conference to insist on evaluation as a condition of aid.
Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global climate. However, these algae, which measure only a few micrometers, have yet another amazing ability: they can "smell" stones.
Researchers have constructed the first comprehensive model of how neurons in the brain behave when faced with a complex decision-making process, and how they adapt and learn from mistakes.
Researchers have patented a new method that allows to identify the cells causing metastasis in cancer, with a simple blood analysis.
Where does the acoel flatworm belong in the tree of life? Biologists have discussed this question for the last 20 years. Now new research suggests that researchers have found the answer.
Over sixty soil experts have gone together and provided an up to date overview of European soil threats. The extensive report, which among other things provides information on the geographical spread of eleven soil threats, also addresses what kind of effect these threats may have on soil functions and ecosystem services, and why they occur.
Scientists have carried out an experiment which conclusively proves for the first time that mitochondria are major triggers of cell aging. This brings scientists a step closer to developing therapies to counteract the aging of cells, by targeting mitochondria.
Scientists are a step closer to preventing the kind of injuries that affect aging race horses like champion hurdler Rock on Ruby, the winner of Coral Hurdle at Ascot in 2015.
Using corticosteroids in mothers at risk for late preterm delivery reduced the incidence of severe respiratory complications in their babies, new research indicates. The new study enrolled more than 2,800 pregnant women deemed at high risk of delivery during the late preterm period (34-36 weeks of gestation). The women were randomized to receive two injections of the steroid betamethasone or a placebo, given 24 hours apart.
The incidence of childhood and adult obesity has increased significantly over the past three decades. New research shows that there is an association between obesity development during adulthood and childhood attention deficit hyperactivity disorder.
Clinics and hospitals across the country are adding physician's assistant (PA) positions to serve growing numbers of patients, and in underserved rural areas, practices are turning to PAs to help expand access to care.
More should be done to stop the use of endangered species in traditional Chinese medicines, with snow leopard, tiger and rhinoceros DNA still being found in remedies, according to a leading pathologist.
Potential new approaches to treating eye diseases such as age-related macular degeneration (AMD) are described in a new study. Scientists discovered that a signaling protein, or cytokine, called IL-33, plays a key role in recruiting phagocytes to damaged retina and induces retinal degeneration. Blocking the IL-33 receptor inhibits this process and prevents injury-induced retinal degeneration.
Diabetes patients traditionally monitor their daily blood glucose levels by using a conventional meter which requires blood sampling from the finger tips. The discomfort of pain and risk of infection can sometimes be a source of great stress and concern. A new method of measuring blood glucose using far infrared light has been developed by researchers who say that it is entirely harmless and non-invasive.
A new model helps understand for example defects formed in metal production.
In contrast to animals, plants form new organs throughout their entire life, such as roots, branches, flowers and fruits. Researchers wanted to know to what extent plants follow a pre-determined plan in the course of this process. In a new article, they describe the growth of secondary roots of thale cress (Arabidopsis thaliana). They have observed it cell by cell in a high-tech optical microscope and analysed it with computer simulations. Their conclusion: root shape is determined by a combination of genetic predisposition and the self-organization of cells.
