Airborne mapping sheds light on climate sensitivity of California redwoods

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...

Introducing a new isotope: Mendelevium-244

A team of scientists working at Lawrence Berkeley National Laboratory (Berkeley Lab) has discovered a new form of the human-made element mendelevium. The newly created isotope, mendelevium-244, is the 17th and lightest form of mendelevium, which is element 101 on the periodic table.

Simple device monitors health using sweat

A device that monitors health conditions in the body using a person's sweat has been developed by Penn State and Xiangtan University researchers, according to Huanyu "Larry" Cheng, assistant professor of engineering science and mechanics, Penn State.

NASA analyzes the newest Atlantic Ocean subtropical depression

NASA's Aqua satellite used infrared light to analyze the strength of storms in the North Atlantic Ocean's newly formed Subtropical Depression 4. Infrared data provides temperature information to find the strongest thunderstorms that reach high into the atmosphere which have the coldest cloud top temperatures.

Welfare concerns highlighted over 'institutional hoarding' of cats

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...

NASA satellite gives a hello to tropical storm Dolly

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.

Innovative smartphone-camera adaptation images melanoma and non-melanoma

An article published in the Journal of Biomedical Optics (JBO), "Point-of-care, multispectral, smartphone-based dermascopes for dermal lesion screening and erythema monitoring," shows that standard smartphone technology can be adapted to image skin lesions, providing a low-cost, accessible medical diagnostic tool for skin cancer.

Slow-growing rotavirus mutant reveals early steps of viral assembly

Rotavirus is responsible for more than 130,000 deaths in infants and young children younger than five years, every year. The virus causes severe, dehydrating diarrhea as it replicates in viral factories called viroplasms that form inside infected cells. Viroplasms have been difficult to study because they normally form very quickly, but a serendipitous observation led researchers at Baylor College...

Tool to protect children's online privacy

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).

Universal flu vaccine may be more challenging than expected

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.

Prenatal stress associated with infant gut microbes

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.
