Study finds scientific reproducibility does not equate to scientific truth

Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers. Their study, which simulates the search for that scientific truth, will be published Wednesday, May 15, in the journal PLOS ONE.

Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans

Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

How loud is too loud when it comes to sports whistles?

How loud is too loud when it comes to whistle tweets? Referees and others using whistles on the job need a simple way to determine whether it's harmful to their hearing, so a group of researchers set out to put it to the test and to provide some clarity and damage risk criteria for impulse noise exposures.

What are the neurological side effects of CAR T-cell therapy?

The recent advent of chimeric antigen receptor (CAR) T-cell therapy has revolutionized the clinical treatment of cancer. Under the umbrella of immunotherapy, CAR T-cell treatment trains and strengthens a patient's own immune system to attack tumors. Early successes in clinical trials have led to approval of the treatment for recurrent blood cancers, including leukemia and lymphoma.

Transfer of EU powers leads to silent erosion of UK pesticide regulation

New analysis by the UK Trade Policy Observatory is warning that what should have been the technical formality of transferring EU powers into national law when the UK leaves the European Union, could instead open the gates for the widespread use of outlawed carcinogenic pesticides that have been shown to alter human reproductive, neurological, and immune systems.

What artificial intelligence can teach us about proteins

Proteins are vital parts of all living organisms and perform essential tasks in our bodies. They build and repair tissues, supply components of the immune and hormone systems, regulate metabolism, and transmit signals. Researchers in Berlin and Heidelberg have now developed an intelligent neural network that can predict the functions of proteins in the human body. The team used a "trick" to observe how the network makes it predictions. The insights gained from this research could help in the search for new targeted drugs.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear

Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

Ancient fish ponds in the Bolivian savanna supported human settlement

A network of fish ponds supported a permanent human settlement in the seasonal drylands of Bolivia more than one thousand years ago, according to a new study published May 15, 2019 in the open-access journal PLOS ONE by Gabriela Prestes-Carneiro of Federal University of Western Para, Brazil, and colleagues. The study is the first to document the full range of fish species likely kept in these constructed ponds, and provides new insights into how humans modified the savannah environment to cope with the months-long droughts that characterize this region of the Amazon Basin.

Twitter image colors and content could help identify users with depression, anxiety

Twitter users with depression and anxiety were found to be more likely to post pictures with lower aesthetic values and less vivid colors, particularly images in grayscale, according to a new study led by researchers at Penn Medicine. Additionally, they found that users tended to suppress positive emotions rather than outwardly display more negative emotions, such as keeping a straight face instead of outright frowning, in their profile pictures. The study sought to utilize computer vision and artificial intelligence to determine what qualities of photos posted to and set as profile images on Twitter could be associated with depression and anxiety, with an eye toward using the platform as a method of screening for both. The research will be presented at the International AAAI Conference on Web and Social Media June 11-14 in Munich.

Dolphin ancestor's hearing was more like hoofed mammals than today's sea creatures

Vanderbilt University paleontologists are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make—part of the rare echolocation ability that allows them to effectively navigate their dark environment.
