First evidence of snake-like venom glands found in amphibians

Caecilians are limbless amphibians that can be easily mistaken for snakes. Though caecilians are only distantly related to their reptilian cousins, researchers in a study appearing July 3 in the journal iScience describe specialized glands found along the teeth of the ringed caecilian (Siphonops annulatus), which have the same biological origin and possibly similar function to the venom glands of...

Getting a grasp on India's malaria burden

A new approach could illuminate a critical stage in the life cycle of one of the most common malaria parasites. The approach was developed by scientists at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) in Japan and published in the Malaria Journal.

Towards lasers powerful enough to investigate a new kind of physics

In a paper that made the cover of the journal Applied Physics Letters, an international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression of light pulses, would make it possible to reach a threshold intensity for a new type of physics that has never been explored before: quantum electrodynamics phenomena.


A path to new nanofluidic devices applying spintronics technology

Japanese scientists have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller. They experimentally demonstrated the fluid power generation phenomenon in the laminar flow region and confirmed that in the laminar flow region, energy...

A scientific measure of dog years

How old is your tail-wagging bundle of joy in human years? According to the well-known "rule of paw," one dog year is the equivalent of 7 years. Now, in a study published July 2, in the journal Cell Systems, scientists say it's wrong. Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog's age based on the chemical changes in the DNA as organisms...

Algae as living biocatalysts for a green industry

Many substances that we use every day only work in the right 3D structure. Natural enzymes could produce these in an environmentally friendly way - if they didn't need a co-substrate that is expensive to produce to date. A research team at Ruhr-Universität Bochum (RUB) has discovered exactly the necessary enzymes in unicellular green algae.

Antioxidant treatment in acute ischemic stroke may delay the onset of Alzheimer's dementia

There is a considerable overlap between vascular and Alzheimer's disease (AD) risk factors. In addition, incident stroke approximately doubles the risk of developing AD. Oxidative stress is significantly involved in the pathogenesis of AD and suffers a dramatic increase in the setting of acute ischemic stroke, especially in cardioembolic stroke, followed by lacunar stroke, as shown in a previous...

Apgar score effective in assessing health of preterm infants

The vitality of preterm infants should be assessed with an Apgar score, a tool used to measure the health of newborns immediately after birth. That is the conclusion by researchers at Karolinska Institutet in Sweden who in a large observational study examined the value of Apgar scores for preterm infants. The findings are published in the New England Journal of Medicine.

Blood tests can predict the risk of liver cirrhosis

Repeated measurements of the biomarker FIB-4 in the blood every few years can predict the risk of developing severe liver disease, according to a new study from Karolinska Institutet in Sweden published in the Journal of Hepatology. The risk of liver cirrhosis increases if the levels of this biomarker rise between two testing occasions.

Call for immunology to return to the wild

In an article published today in Science, a multidisciplinary research team from more than 10 universities and research institutes outlines how integrating a more diverse set of species and environments could enhance the biomedical research cycle.

Center for BrainHealth advances understanding of brain connectivity in cannabis users

Center for BrainHealth® recently examined underlying brain networks in long-term cannabis users to identify patterns of brain connectivity when the users crave or have a desire to consume cannabis. While regional brain activation and static connectivity in response to cravings have been studied before, fluctuations in brain network connectivity had not yet been examined in cannabis users. The...
