To do the job well, they must be ready to make split-second decisions based on incomplete information to stop their opponents from scoring a goal. Now researchers have some of the first solid scientific evidence that goalkeepers show fundamental differences in the way they perceive the world and process multi-sensory information.

The strength of compensation by the cerebral cortex determines how many symptoms people have. Patients can stimulate this compensation through sports, for example, and thus slow down the disease process.

But if you saw that same face upside down, it's much harder to place. Now researchers who've studied Claudio, a 42-year-old man whose head is rotated back almost 180 degrees such that it sits between his shoulder blades, suggest that the reason people are so good at processing upright faces has arisen through a combination of evolution and experience.

While the sound of fire crackling may be ambiguous, its scent confirms the burning wood. Our senses synergize to give a comprehensive understanding, particularly when individual signals are subtle. The collective sum of biological inputs can be greater than their individual contributions. Robots tend to follow more straightforward addition, but researchers have now harnessed the biological concept for application in artificial intelligence (AI) to develop the first artificial, multisensory integrated neuron.

There's a scientific basis for that belief, according to a new study. In two experiments, volunteers consistently said that images of players in jerseys numbered 10 to 19 looked thinner than players in jerseys numbered 80 to 89, even when the bodies were the same size. The finding suggests that people's previously learned associations between numbers and sizes influence their perceptions of body size.

They played different music mixes to listeners with and without hearing loss and found that those with hearing loss preferred louder lead vocals, higher frequencies, and sparser mixes with fewer frequencies overall. Previous research has found that music steadily shifted to quieter vocals and louder instrumentals leading up to 1975, meaning today's music may be less accessible to those with hearing loss.

The new understanding matters because it may impact recovery and rehabilitation following a brain injury such as a stroke.

These new findings are an important piece of the puzzle in explaining what happens in the ear in hearing impairment caused by harmful noise, and may in the long run contribute to diagnosing noise-induced hearing injury.
