Molecular switch detects metals in the environment

EurekAlert! - Mar, 08/14/2018 - 22:00
A team led by researchers from the University of Geneva, Switzerland, has designed a family of molecules capable of binding to metal ions present in its environment and providing an easily detectable light signal during binding. This new type of sensor forms a 3D structure whose molecules consist of a ring and two luminescent arms that emit a particular type of light in a process called circular polarized luminescence, and detect ions, such as sodium.

Restoring blood flow may be best option to save your life and limb

EurekAlert! - Mar, 08/14/2018 - 22:00
Amputation for severe blockages in the lower limbs has a lower survival rate than other treatment options that restore blood flow. Treatment options to restore blood flow to the lower limbs are less expensive than amputation.

How ugly marital spats might open the door to disease

EurekAlert! - Mar, 08/14/2018 - 22:00
Married people who fight nastily are more likely to suffer from leaky guts -- a problem that unleashes bacteria into the blood and can drive up disease-causing inflammation, new research suggests.

Common Wifi can detect weapons, bombs and chemicals in bags

EurekAlert! - Mar, 08/14/2018 - 22:00
Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a Rutgers University-New Brunswick-led study. The researchers' suspicious object detection system is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional screening typically requires high staffing levels and costly specialized equipment.

App that will extend your smartphone battery life

EurekAlert! - Mar, 08/14/2018 - 22:00
New research out of the University of Waterloo has found a novel method to extend the battery life of smartphones for up to an hour each day.

Eating breakfast burns more carbs during exercise and accelerates metabolism for next meal

EurekAlert! - Mar, 08/14/2018 - 22:00
New research published in the American Journal of Physiology suggests that eating breakfast could 'prime' the body to burn carbohydrates during exercise and more rapidly metabolise foods after working out.

Model way to protect trees

EurekAlert! - Mar, 08/14/2018 - 22:00
New research unravels the dynamics of tree production, economics and variability in demand to show how to reduce the risks of importing such damaging forest pests and diseases as oak processionary moth and ash dieback.

Taking a deep look: a near infrared fluorescent dye for long term bioimaging

EurekAlert! - Lun, 08/13/2018 - 22:00
A team of researchers at Nagoya University, RIKEN and Ehime University has succeeded in developing a photostable fluorescent labeling agent that allows long term bioimaging of living cells in the near infrared region. This new fluorescent probe has demonstrated its use for long term single molecule, multicolor and 3D deep imaging.

Effective material developed to prevent post-surgical adhesion

EurekAlert! - Lun, 08/13/2018 - 22:00
In a paper published in TECHNOLOGY, a group of researchers have investigated a novel Polyelectrolyte complex (PEC) that provides a barrier to prevent adhesions in post-operative complications. This has the potential to avoid the need for a second surgery to remove the adhesions.

Discovery casts dark shadow on computer security

EurekAlert! - Lun, 08/13/2018 - 22:00
Two international teams of security researchers have uncovered Foreshadow, a new variant of the hardware vulnerability Meltdown announced earlier in the year, that can be exploited to bypass Intel Processors' secure regions to access memory and data.

Potent psychedelic DMT mimics near-death experience in the brain

EurekAlert! - Lun, 08/13/2018 - 22:00
A powerful psychedelic compound found in ayahuasca can model near-death experiences in the brain, a study has found.

Shivering in the cold? Exercise may protect against muscle fatigue

EurekAlert! - Lun, 08/13/2018 - 22:00
New research published in The Journal of Physiology highlights how exercise could help people exposed to extreme temperatures protect themselves from the cold. This could be useful for people who live and work in very cold conditions.

Brain scan checklist set to boost care for stroke survivors

EurekAlert! - Lun, 08/13/2018 - 22:00
People who suffer a stroke caused by bleeding in the brain could be helped by four simple checks of their brain scans, research led by the University of Edinburgh suggests. The checks could help spot people at risk of further bleeding so they can be monitored more closely. Experts say this could help improve outcomes for the millions of people around the world who experience a brain bleed each year.

Overall stroke death rates decline in Europe but level off or increase in some countries

EurekAlert! - Lun, 08/13/2018 - 22:00
New research, published in the European Heart Journal, has shown deaths from conditions that affect the blood supply to the brain, such as stroke, are declining overall in Europe but that in some countries the decline is leveling off or death rates are even increasing. Cerebrovascular disease includes strokes, mini-strokes, and narrowing, blockage or rupturing of the blood vessels supplying blood to the brain, and it is the second single largest cause of death in Europe after heart disease.

New method makes spinning collagen microfibres quicker, cheaper, and easier

EurekAlert! - Lun, 08/13/2018 - 22:00
Scientists in Norfolk, VA (USA) have developed a new method of making collagen microfibres, which could have applications in research, medical devices and clinical treatments ranging from ligament damage to skin burns.

Secondhand smoke increases risk of children developing arthritis later in life

EurekAlert! - Lun, 08/13/2018 - 22:00
A new study in the journal Rheumatology indicates that being exposed to secondhand smoke in childhood could increase the risk of someone developing arthritis as an adult.

When mixing granular matter, order among disorder

EurekAlert! - Lun, 08/13/2018 - 22:00
Researchers find mixed and non-mixed regions among tumbled granular particles, providing a new understanding of how sand, concrete, and paint mix.

Research brief: UMN researchers use green gold to rapidly detect and identify harmful bacteria

EurekAlert! - Lun, 08/13/2018 - 22:00
Researchers from the University of Minnesota (UMN) have developed a method to screen and identify harmful or antibiotic-resistant bacteria within one hour using a portable luminometer.

Scientists pinpoint brain networks responsible for naming objects

EurekAlert! - Lun, 08/13/2018 - 22:00
Scientists at The University of Texas Health Science Center at Houston (UTHealth) have identified the brain networks that allow you to think of an object name and then verbalize that thought. The study appeared in the July issue of BRAIN. It represents a significant advance in the understanding of how the brain connects meaning to words and will help the planning of brain surgeries.

Societies recommend policies to retain, increase ranks of ID physician scientists

EurekAlert! - Lun, 08/13/2018 - 22:00
Improved compensation, expanded mentorship and training opportunities, and concrete measures to improve workforce diversity are all needed to address attrition from the ranks of physician scientists specializing in infectious diseases, and to ensure that the next generation of that work force is sufficient to bring quests for new life-saving treatments and cures to fruition, according to recommendations released today by IDSA, HIVMA and PIDS.
