Weaponizing oxygen to kill infections and disease

Sunday August 19th, 2018 08:07:16 PM
The life-threatening bacteria MRSA can cripple a medical facility since it is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics, instead using light to activate oxygen, which wipes out bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.

A paper battery powered by bacteria

Sunday August 19th, 2018 08:07:13 PM
In remote areas of the world, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be too expensive. Today, researchers report a new type of battery -- made of paper and fueled by bacteria -- that could overcome these challenges.

Acid coastal seas off US putting common fish species at risk

Saturday August 18th, 2018 03:58:10 PM
Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod.

World's first-ever 4D printing for ceramics

Saturday August 18th, 2018 03:58:03 PM
A ground-breaking advancement in materials research by successfully developing the world's first-ever 4D printing for ceramics, which are mechanically robust and can have complex shapes. This could turn a new page in the structural application of ceramics.

Water-worlds are common: Exoplanets may contain vast amounts of water

Saturday August 18th, 2018 03:57:58 PM
Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy.

Making aquafeed more sustainable: Scientists develop feeds using a marine microalga co-product

Saturday August 18th, 2018 03:56:45 PM
Scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia.

Insight into development of lung cancer

Saturday August 18th, 2018 03:56:27 PM
Lung cancer results from effects of smoking along with multiple genetic components. A new study identifies two main pathways for the role of chromosome 15q25.1 -- a leader in increasing susceptibility to lung cancer -- in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung cancer cause and development.

Engineering team designs technology for smart materials

Saturday August 18th, 2018 03:56:10 PM
With inspiration from squid ring teeth, a multidisciplinary team has invented a novel way to manufacture smart materials, including fabrics, that can regulate their own thermal properties.

Chemistry professor develops contaminant detection technique for heparin

Saturday August 18th, 2018 03:56:07 PM
In 2008, a contaminant eluded the quality safeguards in the pharmaceutical industry and infiltrated a large portion of the supply of the popular blood thinner heparin, sickening hundreds and killing about 100 in the US.

A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'

Saturday August 18th, 2018 03:56:02 PM
Researchers have made a finding that could help usher in new area of technology called 'valleytronics.' The study found that electrons in bismuth crystals prefer to collect in one valley rather than being distributed equally across valleys, setting up a type of electricity known as ferroelectricity.

Perinatal hypoxia associated with long-term cerebellar learning deficits and Purkinje cell misfiring

Saturday August 18th, 2018 03:55:48 PM
The type of hypoxia that occurs with preterm birth is associated with locomotor miscoordination and long-term cerebellar learning deficits but can be partially alleviated with an off-the-shelf medicine, according to a study using a preclinical model.

Students more likely to eat school breakfast when given extra time, new study finds

Saturday August 18th, 2018 03:55:27 PM
Using food weighting stations, the researchers collected information on the number of students who ate a school breakfast, how much they ate, and their exact nutritional intake.

A novel synthetic antibody enables conditional 'protein knockdown' in vertebrates

Friday August 17th, 2018 07:03:25 PM
Researchers have developed a novel synthetic antibody that paves the way for an improved functional analysis of proteins.

Astronomers observe cosmic steam jets and molecules galore

Friday August 17th, 2018 07:03:22 PM
A team of scientists using the highest-frequency capabilities of the Atacama Large Millimeter/submillimeter Array (ALMA) has uncovered jets of warm water vapor streaming away from a newly forming star. The researchers also detected the 'fingerprints' of an astonishing assortment of molecules near this stellar nursery.

Ants, acorns and climate change

Friday August 17th, 2018 07:03:19 PM
The relatively swift adaptability of tiny, acorn-dwelling ants to warmer environments could help scientists predict how other species might evolve in the crucible of global climate change, according to biologists.

Like shark attacks and the lottery, unconscious bias influences cancer screening

Friday August 17th, 2018 07:03:17 PM
Study shows that doctors with personal experience of cancer are more likely to act against established guidelines to recommend that low-risk women receive ovarian cancer screening.

HIV and a tale of a few cities

Friday August 17th, 2018 07:03:14 PM
In a pair of new modeling studies, researchers examined how policy reform in terms of drug decriminalization (in Mexico) and access to drug treatment (in Russia) might affect two regions hard hit by the HIV pandemic: Tijuana, Mexico and the Russian cities of Omsk and Ekaterinburg.

Exploring the relationship between fever and cancer incidence

Friday August 17th, 2018 07:03:11 PM
In a new paper, researchers propose a mechanistic hypothesis that focuses on the potential impact infectious fever has on a particular subset of T cells, known as gamma/delta T cells.

New way to grow blood vessels developed

Friday August 17th, 2018 07:03:08 PM
Formation of new blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels.

Automated detection of focal epileptic seizures in a sentinel area of the human brain

Friday August 17th, 2018 07:03:06 PM
In a first-in-humans pilot study, researchers have identified a sentinel area of the brain that may give an early warning before clinical seizure manifestations from focal epilepsy appear. They have also validated an algorithm that can automatically detect that early warning. These two findings offer the possibility of squelching a focal epilepsy seizure -- before the patient feels any symptoms -- through neurostimulation of the sentinel area of the brain.
