Scientists have used florescent proteins from jellyfish to help shed new light on how DNA replicates.
Intracranial pathology not necessary for gadolinium deposition in brain tissues
Tue, 27 Jun 2017 07:36:03 EDT
New research suggests gadolinium retention may be more widespread and may be present in many more, or possibly all, patients exposed to gadolinium-based contrast agents, according to new research.
Amber warning for the UK's access to new medicines post Brexit
Tue, 27 Jun 2017 07:36:00 EDT
A new study explores the consequences of a British exit from the European Medicines Agency as a result of Brexit, and what this will mean for pharmaceutical regulation and future access to medicines for UK citizens.
Could humans ever regenerate a heart? A new study suggests the answer is 'yes'
Mon, 26 Jun 2017 19:06:25 EDT
A new study's findings point to potential for tweaking communication between human genes and advancing our ability to treat heart conditions and stimulate regenerative healing.
Sequencing finds rare genetic disease risk in one out of five healthy adults
Mon, 26 Jun 2017 19:06:16 EDT
Whole-genome sequencing found risk for rare genetic disease in 1 out of 5 generally healthy patients in primary care. The majority of those findings were not associated with clinical features of the disease in the patients, but prompted some increased costs for evaluation. While some primary care physicians may be able to manage genomic information appropriately, findings could prompt increased health care use with limited clinical value.
Night shifts may hinder body's ability to repair DNA damage
Mon, 26 Jun 2017 19:06:13 EDT
Night shift work may hinder the body's ability to repair DNA damage caused by normal cellular processes, suggests a small study.
Odd properties of water and ice explained: Water exists as two different liquids
Mon, 26 Jun 2017 19:06:10 EDT
Scientists have discovered two phases of liquid water with large differences in structure and density. The results are based on experimental studies using X-rays.
Persistent mental distress linked to higher risk of death in heart patients
Mon, 26 Jun 2017 19:06:07 EDT
Persistent moderate to severe mental distress is linked to a significantly heightened risk of death among patients with stable coronary heart disease, finds research.
Exposure to light causes emotional and physical responses in migraine sufferers
Mon, 26 Jun 2017 18:11:19 EDT
Light makes migraine headaches more painful and induces negative emotions and unpleasant physical sensations, new research confirms. Laboratory studies identify previously unknown connections between nerve cells in the eye and neurons in the brain that regulate physiological, autonomic, endocrine and emotional responses. These findings offer promising path forward for researchers in treatment of migraines.
Could this strategy bring high-speed communications to the deep sea?
Mon, 26 Jun 2017 18:10:47 EDT
A new strategy for sending acoustic waves through water could potentially open up the world of high-speed communications to divers, marine research vessels, remote ocean monitors, deep sea robots, and submarines. By taking advantage of the dynamic rotation generated as the acoustic wave travels, also known as its orbital angular momentum, researchers were able to pack more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.
Thwarting metastasis by breaking cancer's legs with gold rods
Mon, 26 Jun 2017 18:10:45 EDT
Your cancer has metastasized. No one wants to ever hear that. Now researchers have found a way to virtually halt cell migration, a key component in metastasis, in vitro, in human cells. In past in vivo studies in mice, treated cancer did not appear to recur. No significant side effects were observed.
New class of 'soft' semiconductors could transform HD displays
Mon, 26 Jun 2017 18:10:43 EDT
New research could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of “soft” semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.
Blocking cancer: Scientists find new way to combat disease
Mon, 26 Jun 2017 18:10:41 EDT
A newly developed compound shows promise for blocking cancer-causing proteins on a cellular level, outlines a new report.
Tracking bacterial movement between humans, animals key to understanding antibiotic resistance
Mon, 26 Jun 2017 18:09:55 EDT
In a new study, researchers treated bacteria the way they would any ecosystem, using genomic "tags" to track bacterial transmission.
Hunting microbes or smelling poison: A matter of evolution
Mon, 26 Jun 2017 18:09:12 EDT
Mammals possess several lines of defense against microbes. One of them is activated when receptors called Fprs, which are present on immune cells, bind to specific molecules that are linked to pathogens. Researchers showed in 2009 that these same receptors were also present in the nose of mice, probably to detect contaminated food or to avoid sick conspecifics. The biologists now describe how Fprs have acquired this olfactory role during rodent evolution, moving from the immune system to a neuronal system.
Alzheimer's disease risk linked to a network of genes associated with myeloid cells
Mon, 26 Jun 2017 18:06:03 EDT
Researchers have found that a network of genes associated with myeloid cells is central to Alzheimer's disease susceptibility.
Collapse of European ice sheet caused chaos in past
Mon, 26 Jun 2017 18:05:57 EDT
Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.
Team launches 'comb and copter' system to map atmospheric gases
Mon, 26 Jun 2017 15:57:51 EDT

Animals, not drought, shaped our ancestors' environment
Mon, 26 Jun 2017 15:57:45 EDT
The expansion of grasslands isn't solely due to drought, but more complex climate factors are at work, both for modern Africans now and ancient Africans in the Pleistocene, suggests new research.
