Research team takes new approach to studying differences between human and monkey brains

(Medical Xpress) -- In order to provide more insight into how human and monkey brains are similar and how they’re different, a research team has taken a different approach to studying both to find out which parts of the brains of each respond in similar ways, and which, if any, differ, when exposed to a shared experience. In this case, the team, as they describe in their paper published in...

Toward a global microwave standard

Much of what is known about decadal climate change – and much of what appears on the evening weather forecast as well – comes from satellite-based remote sensing of microwave radiation at different levels in the Earth's atmosphere. Microwave measurements are generally reported as the apparent temperature of the object being monitored. Yet, at present, there is no accepted...

Science Weekly podcast: Transplants and the future of intensive care

This week, we're focusing on some pivotal stories from the history of science and medicine. First up are human-to-human transplants and intensive care medicine. These are among the greatest successes of post-war medicine, but they also raise some of the most profound ethical questions. Ahead of a discussion at the Royal Institution in London, Kevin Fong, an anaesthetist and physiology lecturer at...

Pew Study: Facebook Users Get More than They Give

The goody-two-shoes among us say it's better to give than to receive. That's not true for the average Facebook user, though. A new study out Friday found that the average user of the world's biggest online social network gets more than they give. That means more messages, more "likes" and more comments. Yes, even more "pokes." Behind all that is Facebook's relatively small group of "power...

New Malware Attacks Target Online Banking

Computer criminals have found a way to hack their way past the latest generation of online banking security techniques, British researchers say. In the scheme, account holders are tricked by an offer of training in a new "upgraded security system" after being logged into the bank's real site, after which money is moved out of their account but evidence of the theft is invisible to the user, the...

A quantum connection between light and motion

(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs its behavior.

Are European kids getting enough vitamin D? Winter weather reopens the debate

The cold snap has well and truly set in across much of Europe, and as temperatures fall, watching our health becomes increasingly more crucial. Keeping our vitamin D levels up during the winter months has long been lauded as an important part of this fight against unforgiving winter climes, particularly for vulnerable groups such as young children.

Children can learn arithmetic faster and better

During the first two years of primary education children can learn to do arithmetic faster and better with the help of a more systematically structured educational programme. For older children, teaching arithmetic with the systematic use of visual aids, such as blocks and strings of beads, has many advantages. This is apparent from the review study by NWO researchers Egbert Harskamp and Annemieke...

Climate risk of toxic shock

The effects of climate change could expose Australians to greater risks from toxic contamination, a leading scientist has warned.

Combined approach to global health can save lives at lower cost

(Medical Xpress) -- The great paradox of global health efforts is that regions of the world most plagued by poverty, poor infrastructure and rampant disease are often the most difficult to support. Now, scientists have demonstrated that confronting several diseases at once can make the most of thinly-stretched donor dollars and national health care budgets, to help to save lives.

Do we no longer care about the collective good?

The Transformation of Solidarity, a book co-edited by University of Queensland sociologist Dr Mara Yerkes, tackles the subject of globalisation of national economies and societies where we put a high value on individual rights and self-expression.

Electrons in concert: A simple probe for collective motion in ultracold plasmas

(PhysOrg.com) -- Collective, or coordinated behavior is routine in liquids, where waves can occur as atoms act together. In a milliliter (mL) of liquid water, 1022 molecules bob around, colliding. When a breeze passes by, waves can form across the surface. These waves are not present in the same volume of air, where only 1019 gas molecules randomly move about.

Looking healthy is more attractive than manliness

(Medical Xpress) -- Having a healthy skin colour is more important in determining how attractive a man is to women than how manly they look. These are the findings of a study carried out by researchers in the School of Psychology at the University of Nottingham Malaysia Campus.

Magnetic research for better brain health

A pioneering therapy that uses magnetic pulses to stimulate the brain to treat conditions such as Parkinson's disease, depression, schizophrenia, epilepsy and stroke is now better understood thanks to researchers from The University of Western Australia and the Université Pierre et Marie Curie in France.
