In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms. To halt the decline, the world needs to rein in both climate change and nutrient pollution, an international team of scientists asserted in a new paper published Jan. 4 in Science.
NASA-NOAA's Suomi NPP satellite passed over Tropical Cyclone Ava as it made landfall along the coast of northeastern Madagascar.
On Jan. 5 at 5:24 a.m. EST (1024 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite showed the eye of Ava over the northeastern coast near Mahavelona. Mahavelona is a town located in the district of Toamasina II, in the region of Atsinanana. The eye is about 10 nautical miles wide on satellite imagery.
RIVERSIDE, Calif. - Tobacco shops, also known as smoke shops, may represent potential "nuisance properties" in urban communities of color, a study led by a researcher at the University of California, Riverside has found. Nuisance properties are properties where unsafe activities affecting public health and safety occur repeatedly.
In a study spanning two decades, a team of researchers led by Colorado State University found declining numbers of soil fauna, nematodes and other animal species in the McMurdo Dry Valleys, one of the world's driest and coldest deserts. This discovery is attributed to climate change, which has triggered melting and thawing of ice in this desert since an uncharacteristically warm weather event in 2001.
Taking paracetamol during pregnancy may impair the future fertility of female offspring, according to a review published in Endocrine Connections. The article reviews three separate rodent studies that all report altered development in the reproductive systems of female offspring from mothers given paracetamol during pregnancy, which may impair their fertility in adulthood.
TALLAHASSEE, Fla. -- Accelerating ocean acidification could be transforming the fundamental structure of California mussel shells, according to a new report from a Florida State University-led team of scientists.
BELLINGHAM, Washington, USA, and CARDIFF, UK -- In a proof-of-principle case report, researchers announce that targeted fluorescence successfully identified pulmonary metastases in a patient with osteosarcoma, making it easier for surgeons to locate the tumors for resection. This advance is reported in an article published today by SPIE, the international society for optics and photonics.
Newly identified germline variations in a key tumor suppressor gene predispose individuals to develop leukemia as children and leave them with a 1-in-4 chance of developing a second cancer later. St. Jude Children's Research Hospital scientists led the study, which appears today in the Journal of Clinical Oncology.
LAWRENCE, Kan. - With global warming an ever-present worry, renewable energy - particularly solar power -- is a burgeoning field. Now, two doctoral students in the School of Architecture & Design (Arc/D) have demonstrated methods of optimizing the capture of sunlight in experiments at the Center for Design Research.
The World Health Organization (WHO) has been accused of "washing its hands of older people" in its proposed priorities for future work.
In a letter published online in The Lancet, experts on ageing from the University of East Anglia (UEA) and the London School of Hygiene & Tropical Medicine (LSHTM) say the draft WHO 13th General Programme of Work makes no reference to older people or to conditions associated with later life, such as dementia.
