A majority of Americans (63%) continue to say they see the effects of climate change in their own communities, and 65% believe that the federal government is doing too little to reduce the impacts of climate change, according to a new Pew Research Center survey.
Throughout California, the effects of climate change are evident from increasing frequencies of intense wildfires and mudslides to widespread and prolonged droughts. These changes also threaten one of California's most iconic endemic species: coastal redwoods. Coastal redwoods are not only some of the tallest and oldest trees on Earth, but redwood forests are also capable of storing three times...

The compulsive hoarding of animals is a poorly understood psychiatric disorder in people. Characterised by failure to provide minimum standards of care, it can result in malnourishment, uncontrolled breeding, overcrowding and neglect. Typically there is denial of this failure and its impact on the animals and people involved. Even less well understood is the growing trend of 'institutional...
During the morning of June 23, the fourth system in the Northern Atlantic Ocean was a subtropical depression. By the afternoon, the subtropical depression took on tropical characteristics and was renamed Dolly. NASA's Terra satellite greeted Tropical Storm Dolly by taking an image of the new tropical storm.

A new study of 100 mobile apps for kids found that 72 violated a federal law aimed at protecting children's online privacy. Researchers developed a tool that can determine whether an Android game or other mobile app complies with the federal Children's Online Privacy Protection Act (COPPA).
'Mommy brain' is a long-held perception that mothers are more forgetful and less attentive. A new study shows that mothers are equally as attentive, or more attentive than, non-mothers.
Some common strains of influenza have the potential to mutate to evade broad-acting antibodies that could be elicited by a universal flu vaccine, according to a new study. The findings highlight the challenges involved in designing such a vaccine, and should be useful in guiding its development.
Mother's chronic prenatal psychological distress and elevated hair cortisol concentrations are associated with gut microbiota composition of the infant, according to a new publication. The results help to better understand how prenatal stress can be connected to infant growth and development.
A five-minute role-play done with men before the birth of their first child predicted the quality of their parenting after the baby arrived, a new study showed.
A navigation algorithm enables drones to learn challenging acrobatic maneuvers. Autonomous quadcopters can be trained using simulations to increase their speed, agility and efficiency, which benefits conventional search and rescue operations.
For Atlantic salmon, size matters when it comes to love. Larger males and females that may spend up to four years at sea produce many more babies, but they are very rare compared to younger fish.
Researchers tested more than 30 samples of used and unused PPE from six specialty textile manufacturers in the United States and found them to be treated extensively with PFAS or constructed with fluoropolymers, a type of PFAS used to make textiles oil and water resistant.
Researchers followed 547 children for a week and measured their media use and sleep patterns. For children who generally struggle to self-regulate their behavior, screen time in the hour before bed was associated with less sleep. Media use in children who scored high on measures of effortful control was not related to less sleep.
