Three steps to better gift card giving

Three steps to better gift card giving

Is it the thought that really counts?

When it comes to giving gift cards, maybe not.

New research from the University of Cincinnati can help even the most thoughtful gift giver avoid the mistake of over-personalization and keep that card from being banished to the bottom of a purse or hidden deep inside a wallet for the next six months.

Dragonflies on the hunt display complex choreography

Dragonflies on the hunt display complex choreography

The dragonfly is a swift and efficient hunter. Once it spots its prey, it takes about half a second to swoop beneath an unsuspecting insect and snatch it from the air. Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have used motion-capture techniques to track the details of that chase, and found that a dragonfly's movement is guided by internal models of its own body and the anticipated movement of its prey. Similar internal models are used to guide behavior in humans.

New 'electronic skin' for prosthetics, robotics detects pressure from different directions

Touch can be a subtle sense, but it communicates quickly whether something in our hands is slipping, for example, so we can tighten our grip. For the first time, scientists report the development of a stretchable "electronic skin" closely modeled after our own that can detect not just pressure, but also what direction it's coming from. The study on the advance, which could have applications for prosthetics and robotics, appears in the journal ACS Nano.

Revolutionary new procedure for epilepsy diagnosis unlocked by research

Pioneering new research by the University of Exeter could revolutionise global diagnostic procedures for one of the most common forms of epilepsy.

Scientists from Exeter have investigated using mathematical modelling to assess susceptibility to idiopathic generalised epilepsy (IGE) by analysing electrical activity of the brain while the patient is in a resting state.

Brain inflammation a hallmark of autism, large-scale analysis shows

While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains. It will be published online Dec. 10 in the journal Nature Communications.

Brain reward circuits respond differently to 2 kinds of sugar

Phoenix, AZ (December 10th, 2014) - The brain responds differently to two kinds of sugar, according to a report today at the American College of Neuropsychopharmacology annual meeting in Phoenix Arizona. The study suggests that fructose heightens the response of brain reward circuits to food cues, promoting feeding behavior.

Saving old information can boost memory for new information

The simple act of saving something, such as a file on a computer, may improve our memory for the information we encounter next, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research suggests that the act of saving helps to free up cognitive resources that can be used to remember new information.

Annual NHS spend on management consultancy has doubled since 2010

Annual NHS spending on management consultancy has doubled from £313m to £640m between 2010 and 2014, despite a promise by Health Secretary Andrew Lansley to 'slash' spending after the 2010 election, reveals an article in The BMJ this week.

This is enough to run three medium sized hospitals or employ about 2000 extra nurses, says David Oliver, a former clinical director at the Department of Health, who obtained the figures through a Freedom of Information request.

Immunizing schoolkids fights flu in others, too

GAINESVILLE, Fla. --- Mathematical models predicted it, and now a University of Florida study confirms it: Immunizing school-aged children from flu can protect other segments of the population, as well.
