The latest analysis looked at data from more than 200,000 women aged 50-74 at recruitment who were followed up for an average of 16 years. The women were randomly allocated to one of three groups: no screening, annual screening using an ultrasound scan, and annual multimodal screening involving a blood test followed by an ultrasound scan as a second line test.
Epigenetic changes drive the fate of a B cell

B cells are the immune cells responsible for creating antibodies, and most produce antibodies in response to a pathogen or a vaccine. A small subset of B cells instead spontaneously make antibodies that perform vital housekeeping functions. Understanding how epigenetics spur these differences in such similar cells is an important fundamental question in immunology.
Politically polarized brains share an intolerance of uncertainty

A new study on political polarization showed how an aversion to uncertainty is often associated with black-and-white political views.
Two-in-one: Wide-angle monitoring meets high-resolution capture in new camera platform
- ScienceDaily
- 21/5/13 23:35
In most cameras, there is a trade-off between the field-of-view and resolution. Omnidirectional cameras offer a 360-degree field of view but poor resolution. In a new study, researchers design a dual camera-based platform employing an omnidirectional camera for target detection and a separate camera for its high-resolution capture and report an overall improved performance, opening doors to...
Force-sensing PIEZO proteins are at work in plants, too
- ScienceDaily
- 21/5/13 23:35
A family of proteins that sense mechanical force--and enable our sense of touch and many other important bodily functions--also are essential for proper root growth in some plants, according to a study led by scientists at Scripps Research and Howard Hughes Medical Institute.
The first frost is the deepest
The first frost of autumn may be grim for gardeners but the latest evidence reveals it is a profound event in the life of plants.

Study of 70,000 individuals links dementia to smoking and cardiovascular disease
- ScienceDaily
- 21/5/13 21:48
In the largest study of the associations between smoking and cardiovascular disease on cognitive function, researchers found both impair the ability to learn and memorize; and that the effects of smoking are more pronounced among females, while males are more impaired by cardiovascular disease.
Understanding how people make sense of the news they consume
How people consume news and take actions based on what they read, hear or see, is different than how human brains process other types of information on a daily basis, according to researchers at the University of Missouri School of Journalism. While the current state of the newspaper industry is in flux, these journalism experts discovered people still love reading newspapers, and they believe a...
Market report: Rising stock wealth does boost spending, employment
The stock market is a staple of business news, but it is unclear how meaningful stock prices are to the larger economy. Do changes in stock prices directly affect shorter-term consumption, or are they just leading indicators for subsequent economic activity? The U.S. Federal Reserve, for its part, usually seems to act as if stock-based wealth does help drive spending and employment. But is this...
Research reveals negative effects of hotel app adoption on customer spending
Companies have often considered app adoption among their customers to have a positive impact on customer spending. According to new research from marketing professor P.K. Kannan at the University of Maryland's Robert H. Smith School of Business, higher app adoption among hotel chains could be linked to lower spending among lower-level loyalty customers, who are more likely to use apps to get the...
The Achilles heel of the coronavirus
Viruses require the resources of an infected cell to replicate and then infect further cells, and transfer to other individuals. One essential step in the viral life cycle is the production of new viral proteins based on the instructions in the viral RNA genome. Following these construction plans, the cell's own protein synthesis machine, called the ribosome, produces the viral proteins.
