When it comes to touch, to give is to receive

A study found that participants consistently rated the skin of another person as being softer than their own, even if it wasn't. This phenomenon, known as the social softness illusion, may exist to ensure humans build social bonds through touch.

Changing patient's position helps effectiveness of colonoscopy -- especially on one side

A study found that examining the right side of the colon while patients lie on their left side increases polyp and adenoma detection. This position change also improved distension of the colon, allowing for better visualization. The results suggest a more effective tool for ongoing surveillance and prevention.

You'd have to be smart to walk this lazy... and people are

A study published in Current Biology found that people subconsciously change their walking patterns to expend the least amount of energy possible. By wearing robotic exoskeletons and altering resistance levels, researchers showed that participants adapt their step frequency to converge on a new energetic optimum within minutes.

Brain cells get tweaked 'on the go'

Researchers at King's College London have discovered a new molecular 'switch' that controls the properties of neurons in response to changes in their neural network. This finding suggests that the brain's hardware is tuneable and could lead to breakthroughs in education policy and neurological therapies.

Clearing a path for cancer research

Researchers at EMBL-EBI have developed a new computational method to study biological signalling pathways and networks, allowing for more precise questions about how drugs affect proteins and pathways. The method uses noisy data from MS experiment, filters the noise, and integrates the data to reconstruct pathways robustly.

UEA research shows revived oceanic CO2 uptake

Research from the University of East Anglia reveals that the Southern Ocean's carbon sink has reinvigorated after a decade of stagnant absorption. The team attributes this change to shifts in wind patterns and temperature, which have led to increased upwelling of deep waters containing higher concentrations of dissolved CO2.

Hastings Center awarded NIH grant

The Hastings Center has received a $1.1 million NIH grant to conduct an ethical analysis of next-generation prenatal genetic tests, informing clinical guidelines and policy recommendations. The project aims to identify principles and values guiding the use of these tests, as well as policies needed to support their ethical use.

Revived oceanic CO2 uptake

The Southern Ocean's carbon sink has revived after 'saturating' since 2005 due to changes in weather patterns. The reinvigoration is attributed to variations in wind and temperature, enabling the ocean to absorb more CO2 from the atmosphere.

Mental math helps monk parakeets find their place in pecking order

A study published in PLOS Computational Biology found that monk parakeets use a complex system of mental math to determine their place in the pecking order. By analyzing aggression patterns, researchers discovered that birds can infer rank based on chains of interactions and adjust their behavior accordingly.

A snapshot of Americans' knowledge about science

A recent study by the Pew Research Center reveals significant differences in Americans' understanding of various science topics, with educational level being a major factor. Adults with higher education tend to perform better on science-related questions, while gender also plays a role, with men generally outperforming women.

Mental math helps monk parakeets find their place in pecking order

A study by the National Institute for Mathematical and Biological Synthesis found that monk parakeets develop an understanding of rank after about a week of interactions. They use social feedback to refine their behavior, avoiding fights with higher-ranked birds while targeting those closely matched in rank.

Less is more

Scientists at Goethe University Frankfurt have developed SLAP technology, a small labeling pair that achieves high sensitivity and efficiency in single-molecule localization microscopy. The approach avoids mislocalization artifacts caused by large detection markers, enabling precise analysis of protein clusters and oligomeric states.
