Zombies are a staple of apocalyptic movies, but not all the living dead are evil. In the guts of

A piece of good news: the Clean Air Act that is meant to protect humans from the dirty air also saving birds, a new study revealed. According to the authors, the improved air quality resulting from a federal program to reduce ozone pollution may have averted the loss of 1.5 billion birds or 20 percent of birdlife

Mud volcanoes are an unpredictable and dangerous phenomenon — but now scientists have

A new method for detecting pyrethroid pesticides in honey that is very harmful to honeybees is now available. University of Waterloo researchers developed a fully automated and environment-friendly technique to extract pyrethroids from samples of honey. Massive Die-Offs of Bees Colony collapse disorder or CCD is a condition wherein the worker honeybees do not return

The entire country is expected to have a dry Thanksgiving Day this year. However, central and southern US states may experience severe storms before Thanksgiving Day.  Severe thunderstorms may likely interfere with the Thanksgiving preparation of residents from northern Texas to the southern parts of Illinois and Indiana and western portions of Kentucky, Tennessee, and Alabama

Scientists have found that animals can surprisingly adapt to the increased temperatures caused by climate change. A 2019 UN report estimated that one million species are currently in danger of extinction. Researchers published in the journal Nature found that tropical ocean ecosystems could collapse by 2030, while mountains and forests will follow by 2050.  Consistently, other reports stated that with the current status

Researchers often complain about the indicators that hiring and grant committees use to judge them. In the past ten years, initiatives such as the San Francisco Declaration on Research Assessment and the Leiden Manifesto have pushed universities to rethink how and when to use publications and citations to assess research and researchers. The use of

A new paper documented the effects of changes in the behavior of fires, from being too large or too little, that threatens biodiversity and ecosystems, including over 4,400 species of birds, mammals, insects, and plants worldwide. According to a paper published by a 27-member international team led by researchers from the University of Melbourne, changes in the behavior of fire

Burning the Books Richard Ovenden John Murray (2020) In 1660, when the British monarchy was restored, the University of Oxford ordered the burning of books by anti-royalist, pro-free-speech poet John Milton. This is one of many graphic examples inspired by the collections at the institution’s Bodleian Library, cited in Bodleian librarian Richard Ovenden’s powerful history,

One of the rarest marine mammals in the world, a calf of the North Atlantic Right Whale, was recently found on North Core Banks. According to the National Park Service at Cape Lookout National Seashore, the calf’s death is unclear. Biologists, however, did a necropsy on Saturday. DNA samples were also taken from the calf
