Being able to recognize and make use of such patterns is lucrative business for companies. Edgar de Graaf discovered that interesting patterns often contain a time aspect. Jeroen De Knijf developed methods to detect relevant patterns quicker. (2008-10-29)

Work absence after breast cancer diagnosis: A population-based study
Elizabeth Maunsell and colleagues report on the work experience of women recently diagnosed with breast cancer. Compared to matched health control women, women with breast cancer who remained free of the disease for at least 3 years after diagnosis were much more likely than healthy women to be absent from work for 4 weeks or more (85% vs. 18%). (2005-09-26)

Altered expression of key developmental genes underlies evolution of butterfly wing patterns
The diverse and colorful wing patterns of butterflies and moths provide some of the most iconic examples of the evolutionary process. Researchers studying gene expression in a range of moth and butterfly species report this week that a certain class of wing patterns has likely evolved through seemingly simple alterations in the timing of various types of gene expression. (2004-07-12)

Bees attracted to contrasting colors when looking for nectar
Flower colors that contrast with their background are more important to foraging bees than patterns of colored veins on pale flowers according to new research by Heather Whitney, University of Cambridge in the UK, and her colleagues. Their observation of how patterns of pigmentation on flower petals influence bumblebees' behavior, is published online in Springer's journal, Naturwissenschaften -- The Science of Nature. (2013-02-21)

Neurons that fire alike are connected in the olfactory map
Filling a notable gap in scientists' understanding of how cells respond to 'smells' and signal to underlying neurons, researchers report that the activated cell receptors cause their cells not simply to fire, but to fire in specific patterns. (2019-06-06)

Evidence human activities have shaped large-scale ecological patterns
A new study published in the Journal of Biogeography provides some of the first evidence that ecological patterns at large spatial scales have been significantly altered within recent human history suggesting a role for human activities as potential drivers. (2006-06-07)

Computer simulations mimic growth of 'dizzy dendrites'
Many of the useful properties associated with metal alloys or polymer blends -- like strength, flexibility and clarity -- stem from a material's specific crystal microstructure. To better understand this microstructure, National Institute of Standards and Technology (NIST) researchers and international collaborators recently used computer simulations of crystal growth to learn how foreign particles affect crystal growth patterns. (2003-06-24)

Making a beeline for the nectar
Bumblebees searching for nectar go for signposts on flowers rather than the bull's eye. A new study, by Levente Orbán and Catherine Plowright from the University of Ottawa in Canada, shows that the markings at the center of a flower are not as important as the markings that will direct the bees to the center. The work is published online in Springer's journal, Naturwissenschaften - The Science of Nature. (2013-06-20)

Drought sensitivity shapes species distribution patterns in tropical forests
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known. This study, published in Nature, explores these patterns. A contingent of researchers from around the world, including Panama, Germany, USA and Canada, have uncovered that tropical plant species distribution patterns are linked to the plant's drought sensitivity. (2007-05-14)

Random movements help color-detecting cells form the proper pattern
In fish and other animals, the color detecting cone cells in the retina are arranged in specific patterns, and this is believed to be important for allowing animals to properly sense their surroundings. Now, in research published in Physical Review E, an interdisciplinary group of physicists and biologists have used a mathematical model to determine how the cone cells in zebrafish -- a common experimental fish model -- are arranged in a specific pattern in all individuals. (2017-10-02)

NIST helps chip industry measure features by counting atoms
In a quest to develop a nanotechnology equivalent of a ruler, NIST researchers have developed a novel device that can resolve distances smaller than the radius of an atom and a reliable method for writing 10-nanometer features on silicon. (2003-08-12)

'Tornado Alley' twisters may be easier to predict in April than in May
Scientists may have uncovered how sea-surface temperature patterns influence the number, strength and distributions of April tornado formation in the south-central region of the United States known as 'Tornado Alley.' Their results underscore how shifting climate patterns potentially affect tornado formation within seasons, which could help reduce fatalities and (2019-08-21)

New research led by scientists from the University of Bristol and Queen Mary University of London has revealed that bumblebees can tell flowers apart by patterns of scent. (2018-06-12)

Ocean warming could drive heavy rain bands toward the poles
In a world warmed by rising atmospheric greenhouse gas concentrations, precipitation patterns are going to change because of two factors: one, warmer air can hold more water; and two, changing atmospheric circulation patterns will shift where rain falls. According to previous model research, mid- to high-latitude precipitation is expected to increase by as much as 50 percent. Yet the reasons why models predict this are hard to tease out. (2014-08-18)

Fish can recognize a face based on UV pattern alone
Two species of damselfish may look identical -- not to mention drab -- to the human eye. But that's because, in comparison to the fish, all of us are essentially colorblind. A new study published online on Feb. 25 in Current Biology, a Cell Press publication, reveals that the fish can easily tell one species from another based entirely on the shape of the ultraviolet patterns on their faces. (2010-02-25)

Alan Newell of the University of Arizona will give the talk, (2011-02-18)

The hidden threat posed by inconspicuous stripes
Patterns fascinate. Particularly stripes. Found in nature in zebras, they are also found in the most unlikely places, such as powdered drugs' mixing vessel walls. In an article about to be published in EPJ E, Nirmal Thyagu and his colleagues from Rutgers University, New Jersey, USA, propose a traffic model to predict the formation of different patterns, ranging from stripes to spots. (2012-10-22)

Breakthrough model reveals evolution of ancient nervous systems through seashell colors
Determining the evolution of pigmentation patterns on mollusk seashells -- which could aid in the understanding of ancient nervous systems -- has proved to be a challenging feat for researchers. Now, however, through mathematical equations and simulations, University of Pittsburgh and University of California, Berkeley, researchers have used 19 different species of the predatory sea snail Conus to generate a model of the pigmentation patterns of mollusk shells. (2012-01-12)

Make an October weight resolution
You probably weigh less this week than you'll weigh any week over the entire year! If you're an average American, your weight starts to rise from this week on. The culprit? The holiday season -- Halloween, Thanksgiving, Christmas, and New Year's. (2016-10-04)

Moving targets: when it comes to patterns, motion gets factored in
By investigating how our visual system interprets moving images, a Japanese researcher has made new findings that challenge a commonly held view of how we perceive patterns. The findings indicate that the human brain uses the whole visual motion system to integrate spatial pattern information along the trajectory of motion. The work provides an answer to the question of why we can see clear patterns even when they are moving. (2004-05-24)

Brain's GPS system influenced by shape of environment
Patterns created by the brain's grid cells, which are believed to guide navigation, are modified by the shape of the environment, according to University College London researchers including recent Nobel prize winner, professor John O'Keefe. This means grid patterns aren't a universal metric for the brain's GPS system to measure distance, as previously thought. (2015-02-11)

Masters of disguise: Secrets of nature's 'great pretenders' revealed
