The Food and Drug Administration (FDA) today approved Invega (paliperidone) extended-release tablets for the treatment of schizophrenia. Paliperidone is a new molecular entity, which means this medication contains an active substance that has never before been approved for marketing in any form in the United States.
The infrared-sensitive camera on NASA’s Cassini spacecraft photographed a 93-mile unbroken range of nearly mile-high mountains on Saturn’s moon Titan last Oct. 25.
Small insects that inhabit some of the most remote parts of the United States are sending a strong message about climate change. New research suggests that changes in midge communities in some of these areas provide additional evidence that the globe is indeed getting warmer. Researchers created a history of changing midge communities for six remote mountain lakes in the western United States.
Despite growing public alarm over the shrinking Greenland and Antarctic ice sheets, it is small glaciers and ice caps that have been contributing the most to rising sea levels in recent years, according to a new University of Colorado at Boulder study.
Geology topics of interest include: Two New Zealand supervolcanoes that erupted only days or weeks apart; remarkably detailed K-T boundary evidence from the tropical Atlantic’s Demerara Rise supporting a single impact event; and human impact on continental erosion and sedimentation.
Geologists have developed a new theory to explain how and when the Appalachian Mountain range was created. Their research redraws the map of the planet from 420 million years ago.
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist.
The Earth System Science Partnership (ESSP) has recently launched a Monsoon Asia Integrated Regional Study (MAIRS) and will share details of the study, as well as outline research needs and knowledge gaps in the understanding of Monsoon Asia, during several special sessions at the ESSP Open Science Conference.
Researchers who thought they had identified the bacterial perpetrator of the often severe disease caused by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) had better keep looking: Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have exonerated a toxin widely thought to be the guilty party.
For hikers, campers and others who enjoy the outdoors, summer can bring concerns about tick bites and related illnesses such as Rocky Mountain spotted fever. Researchers are investigating the role that antioxidants — alpha-lipoic acid and potentially others like green tea and vitamins C and E, for example – might play in preventing or treating the deadly rickettsia bacteria.
