Even young children know what typical dogs and fish look like -- and they apply that knowledge when they hear new words, reports a team from the Princeton Baby Lab, where researchers study how babies learn to see, talk and understand the world.
Influencer marketing is extremely widespread, yet ineffective. Eighty-six percent of companies use it as part of their social media strategy, but effectiveness remains low. For an influencer on Facebook, the average engagement rate per post is 0.37 percent; on Twitter, it is even lower at 0.05 percent.
New research from the University of Notre Dame provides a framework of strategies to help managers yield larger returns on engagement.
A genome-wide association study (GWAS) and bioinformatic analysis of more than 165,000 U.S. veterans confirms a genetic vulnerability to post-traumatic stress disorder (PTSD), specifically noting abnormalities in stress hormone response and/or functioning of specific brain regions, report scientists in a paper published July 29, 2019 in Nature Neuroscience.
Montmorency tart cherry juice has long been coveted by gout sufferers, athletes for exercise recovery, and those seeking a good night's sleep. Now there's evidence that this polyphenol-rich beverage may help improve cognitive performance in older adults.
Neural activity that reflects the intention to drink alcohol is observed in the prefrontal cortex and is blunted in rats with a family history of excessive drinking, according to research from eNeuro. This insight could lead to novel treatments for alcohol use disorders.
Changing your identity to protect others might sound like something reserved for comic book vigilantes, but a study led by researchers at the Stanford University School of Medicine has found a select group of cells in artery walls do just that.
For these cells, the identity shift happens in a disease called atherosclerosis, which occurs when arteries get clogged by plaque, a buildup of fats, cholesterol and molecular particulate.
Inside the brains of patients with amyotrophic lateral sclerosis, a debilitating neurodegenerative disease, is a telltale sign that marks almost every case: clumps of toxic proteins.
Now, researchers from the Stanford University School of Medicine and their collaborators have pinpointed a key gene behind the formation of one type of these neuron-damaging aggregates. They've also shown how inhibiting the gene's function curbs production of the harmful protein.
NASA's newest planet-hunting satellite has discovered a type of planet missing from our own solar system.
Launched in 2018, the Transiting Exoplanet Survey Satellite, or TESS, has found three new worlds around a neighboring star. Stephen Kane, a UC Riverside associate professor of planetary astrophysics, says the new star system, called TESS Object of Interest, or TOI-270, is exactly what the satellite was designed to find.
For respiratory infections in children under 12, physicians are increasingly more likely to recommend antihistamines and less likely to recommend cough and cold medicines, a Rutgers study found.
Antihistamines are widely used over-the-counter to treat various allergic conditions. However, these medicines have little known benefit for children with colds, and some older antihistamines cause sedation and occasionally agitation in children.
Researchers at North Carolina State University have developed portable technology that allows farmers to identify plant diseases in the field. The handheld device, which is plugged into a smartphone, works by sampling the airborne volatile organic compounds (VOCs) that plants release through their leaves.
A study based on the Million Veteran Program of the U.S. Department of Veterans Affairs has identified multiple locations in the human genome related to the risk of re-experiencing traumatic memories, the most distinctive symptom of posttraumatic stress disorder.
Researchers from the VA Connecticut Healthcare System, Yale University School of Medicine, the VA San Diego Healthcare System, and the University of California San Diego collaborated with colleagues on this large genome-wide association study of more than 165,000 veterans.
SAN FRANCISCO, CA--July 29, 2019--The Komodo dragons are the largest lizards in the world. These predators weighing up to 200 pounds can detect their prey from up to 7.5 miles away. And although they are cold-blooded, they can ramp up their metabolism to near mammalian levels, which gives them great speed and endurance. However, scientists have understood little about how the DNA of these remarkable lizards encodes such astounding characteristics.
A new Portland State University study suggests that bullying bosses aren't just bad for employee morale and well-being -- they can also be bad for workplace safety.
Liu-Qin Yang, an associate professor of industrial-organizational psychology in PSU's College of Liberal Arts and Sciences, and her co-authors surveyed airline pilots and manufacturing technicians and found that employees' safety behavior can be worsened when they're treated in ways that detract from their bonds to a work group.
The study was published in the Journal of Applied Psychology.
Physicists from Nanyang Technological University, Singapore (NTU Singapore) and the Niels Bohr Institute in Copenhagen, Denmark, have devised a method to turn a non-magnetic metal into a magnet using laser light.
Magnets and their magnetic field are typically produced by circulating currents, like those found in everyday electromagnetic coils. The 'handedness' of these coils - whether they are wound in clockwise or anticlockwise fashion - determines the direction of the magnetic field produced.
Real and fake smiles can be tricky to tell apart, but researchers at the University of Bradford have now developed computer software that can spot false facial expressions.
By analysing the movement of the smile across a person's face, the software can determine whether or not the expression is genuine. The most significant movements detected by the software were around the eyes, supporting popular theories that a spontaneous, genuine smile is one that can be seen in a person's eyes.
