University of Washington, Seattle A first step in

University of Washington, Seattle

A first step in learning by imitation, baby brains respond to another’s actions

Imitation may be the sincerest form of flattery for adults, but for babies it’s their foremost tool for learning. As renowned people-watchers, babies often observe others demonstrate how to do things and then copy those body movements. It’s how little ones know, usually without explicit instructions, to hold a toy phone to the ear or guide a spoon to the mouth.

Now researchers from the University of Washington and Temple University have found the first evidence revealing a key aspect of the brain processing that occurs in babies to allow this learning by observation

Scientists discover genetic disease which causes recurrent respiratory infections

Cambridge scientists have discovered a rare genetic disease which predisposes patients to severe respiratory infections and lung damage. Because the scientists also identified how the genetic mutation affects the immune system, they are hopeful that new drugs that are currently undergoing clinical trials to treat leukaemia may also be effective in helping individuals with this debilitating disease.

Mindfulness over matters

Using meditation techniques in classrooms can boost clarity and learning, Kabat-Zinn saysProfessor Jon Kabat-Zinn, a renowned proponent of applying the practice of mindfulness in schools, addressed the Harvard Graduate School of Education (HGSE) Wednesday evening in Longfellow Hall about the effectiveness of such training in countering the pressures and effects of anxiety, stress, chronic pain, and illness on the body, mind, and brain.

The practice of mindfulness, a systematic way of paying attention and cultivating well-being, is becoming an increasingly important tool in education, from top-level leaders to elementary schoolchildren.

« My Years at USU were Very Important to my Development as a Scholar »

Utah State University alum Lars Peter Hansen is one of three Americans named a recipient of the 2013 Nobel Prize in Economics.

Hansen is internationally known for his specialization in economic dynamics, using statistical methods applied to study linkages between financial markets and the macroeconomy. Since joining the University of Chicago in 1981, Hansen is now the David Rockefeller Distinguished Service Professor in Economics and Statistics and is the inaugural research director for the Becker-Friedman Institute. He was named a Nobel Economics Laureate alongside Eugene Fama, also of the University of Chicago, and Robert Shiller of Yale University.

Testing the water

A new online tool enables users to assess not only how much water we use and for what, but also how we can mitigate future scarcity.

Water, like many other natural resources,is in both high demand and limited supply. In any one region, this precious substance is needed to sustain the domestic requirements of the population, irrigate crops, maintain ecosystems and assist in manufacturing and energy production.

Focusing on the state of California, a multidisciplinary group of Cambridge researchers has developed a model to calculate monthly and annual water demand. Moreover, because the model calculates future scenarios, it provides a means of assessing what can be done to mitigate water scarcity.

Stimulate my brain

For every day one has entered a classroom or office and aced a test or presentation, there are other days when grogginess and a lack of focus lead to poor performance.

In the absence of a reliable, safe way to ensure optimal focus each day, a wall of sugar and caffeine-packed energy drinks in every convenience store have become, for some, the go-to “pick-me-up” potion.

Two education professors at The University of Alabama hope transcranial direct current stimulation, or tDCS, can be an answer for students who struggle to learn, recall or retain information.

Drs. Rick Houser and Steve Thoma are searching for a link between low-current brain stimulation, the correct brain cortexes and academic performance. Students enrolled in a junior-level statistics class at UA serve as willing test subjects.

Photons on demand now possible on hair's width optical chip

A breakthrough in photonics that will help create extremely compact optical chips, a hair's width in size and delivering a photon at a time, has been achieved by researchers from the University of Sydney.

"This result has applications in the development of complex quantum technologies, including completely secure communications, quantum measurement, the simulation of biological and chemical systems and of course quantum computing," said Dr Alex Clark, leader of the research team from the Australian Research Council Centre of Excellence for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS).

Carried out at the University of Sydney's School of Physics, the research is published in Nature Communications.

Des pansements de peau humaine pour soigner les ulcères cutanés

Des chercheurs de la Faculté de médecine de l’Université Laval et du CHU de Québec viennent de démontrer qu'il est possible de soigner des ulcères veineux réfractaires aux traitements courants en utilisant des pansements faits de substituts de peau cultivés in vitro. Une étude publiée dans un récent numéro de la revue scientifique Advances in Skin and Wound Care montre que cette approche a permis de soigner les ulcères veineux de personnes aux prises depuis des mois avec de telles plaies au niveau des jambes

UW researchers helped draft international assessment of climate change

The United Nations Intergovernmental Panel on Climate Change late last week released its summary for policy-makers, the Cliffs Notes version of the massive international assessment released about every six years.

The full text of the fifth IPCC report was released today, and University of Washington atmospheric science professors Dennis Hartmann and Chris Bretherton were among 209 researchers from 39 countries who were lead authors on the 900-page report.

Warming is unequivocal,” Hartmann said Friday at a news conference in Sweden. He was a coordinating lead author for Chapter 2, Observations of Atmosphere and Surface, which reviews the evidence for global warming in temperature records. Hartmann also helped draft the technical summary and the summary for policymakers, and was in Stockholm last week for the final line-by-line reviews of the 36-page summary document.

Université du Québec à Montréal

Sur les berges du Rhône

Camille Larivée-Gauvreau, étudiante en histoire de l'art, raconte son séjour d'étude à Lyon.

« Un mois s’est écoulé depuis mon arrivée à Lyon, le 2 septembre dernier, et ce fut un mois intense ! Les deux premières semaines ont été particulièrement éprouvantes, car je devais dénicher rapidement un appartement, une tâche toujours ardue. Après avoir effectué plusieurs recherches, j'ai finalement trouvé un charmant petit studio en périphérie de Lyon.  Situé dans un jardin luxuriant, il appartient à un couple de Lyonnais extrêmement accueillant et sympathique. Une fois installée, il fallait que j'organise ma vie quotidienne et j'ai dû régler mille et un détails, comme obtenir un certificat de scolarité auprès du Service des relations internationales de l'Université Lyon 2 Lumière, ouvrir un compte bancaire français, me procurer un cellulaire, etc.

Quelques jours après mon arrivée, je suis allée à une réunion d’accueil des étudiants étrangers. L'Université Lyon 2 Lumière compte environ 500 étudiants étrangers, inscrits pour un trimestre ou deux. Plusieurs d'entre eux viennent perfectionner leur français, car Lyon 2 Lumière a développé un important Département de langues. Afin de faciliter notre intégration, le Service des relations internationales de l'université a organisé plusieurs activités culturelles au cours des premières semaines, notamment une visite guidée de Lyon conçue par des étudiantes en histoire de l’art. »
