Working with mice, researchers have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote.
A team of neurosurgeons and engineers has developed wireless brain sensors that monitor intracranial pressure and temperature and then are absorbed by the body, negating the need for surgery to remove the devices. Such implants, developed by scientists at Washington University School of Medicine in St. Louis and engineers at the University of Illinois at Urbana-Champaign, potentially could be used to monitor patients with traumatic brain injuries.
Around 720-640 million years ago, much of the Earth’s surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this ‘Snowball Earth’, according to new research led by the University of Southampton.
Analyzing brain scans of 105 children ages 7 to 12, researchers at Washington University in St. Louis have found that key structures in the brain are connected differently in poor children than in kids raised in more affluent settings. In particular, the brain's hippocampus -- a structure key to learning, memory and regulation of stress -- and the amygdala -- which is linked to stress and emotion -- connect to other areas of the brain differently in poor children than in those whose families had higher incomes.
Between 1999 and 2013, there were 5,511 deaths by legal intervention or law enforcement in the U.S., and in 2013, an estimated 11.3 million arrests resulted in approximately 480 deaths from law enforcement.
A new elegant orchid species that grows on rocks in deciduous forests of the Pacific slope of Oaxaca state, Mexico, has finally put an end to a long standing dispute among taxonomists. 'Sheltered' under the name of a close relative, the plant has been proved by a research team, led by Dr. Leopardi-Verde, to be different enough for a species of its own. Its distinct features, including shape, size and colors, are discussed and published in the open-access journal PhytoKeys.

More people in Europe are dying than are being born, according to a new report co-authored by a Texas A&M University demographer. In contrast, births exceed deaths, by significant margins, in Texas and elsewhere in the U.S., with few exceptions.
In atherosclerosis, plaque builds up on the inner walls of arteries that deliver blood to the body. Studying mice and tissue samples from the arteries of patients, researchers at Washington University School of Medicine in St. Louis suggest this accumulation is driven, at least in part, by processes similar to the plaque formation implicated in brain diseases such as Alzheimer’s and Parkinson’s.

Critically ill patients who are exposed to higher daily levels of ozone are more likely to develop acute respiratory disease syndrome (ARDS), according to a new study published online ahead of print in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. ARDS is a life-threatening inflammatory lung illness in which patients fail to obtain enough oxygen to the lungs. While previous research has shown a clear association between cigarette smoke and ARDS, the study “Long-Term Ozone Exposure Increases the Risk of Developing the Acute Respiratory Distress Syndrome” by Lorraine Ware, MD, of Vanderbilt University School of Medicine and colleagues is the first to demonstrate a risk related to ozone.
Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This multiwavelength image shows this galaxy cluster, called IDCS J1426.5+3508, in X-rays recorded by Chandra in blue, visible light observed by Hubble in green, and infrared light detected by Spitzer in red. is so far away that the light detected is from when the universe was roughly a quarter of its current age. This is the most massive galaxy cluster detected at such an early age.
