High-speed quantum encryption may help secure the future internet

24 Nov 2017, 7:28 pm
Quantum encryption may be one step closer to wide-scale use thanks to a newly developed system. The system is capable of distributing encryption codes at megabit-per-second rates, five to 10 times faster than existing methods and on par with current internet speeds when running several systems in parallel. New theory shows that the technique is secure from common security attacks.

Timing is key in keeping organic matter in wet soils, new study finds

24 Nov 2017, 1:49 pm
Periodically flooded soils may actually lose organic matter at accelerated rate, a new report suggests.

Promising new treatment for rare pregnancy cancer leads to remission in patients

24 Nov 2017, 1:49 pm
Three out of four patients with the cancerous forms of gestational trophoblastic disease (GTD) went into remission after receiving the immunotherapy drug pembrolizumab in a clinical trial, report researchers. The trial is the first to show that pembrolizumab can be used to successfully treat women with GTD.

Avatar therapy may help to reduce auditory hallucinations for people with schizophrenia

24 Nov 2017, 1:49 pm
An experimental therapy which involves a face-to-face discussion between a person with schizophrenia and an avatar representing their auditory hallucination may help reduce symptoms, when provided alongside usual treatment, according to a study.

Ambush in a petri dish: Researchers unlock secrets of chemical communication between algae, bacteria

24 Nov 2017, 1:48 pm
If green algae of the species Chlamydomonas reinhardtii meet Pseudomonas protegens bacteria, their fate is sealed. The bacteria, measuring only some two micrometres, surround the algae, which are around five times larger, and attack them with a deadly toxic cocktail. The algae lose their flagella, which renders them immobile. The green single-celled organisms then become deformed and are no longer able to proliferate. The chemical mechanism underlying this extremely effective attack has now been uncovered by botanists and natural product chemists.

Earth-air heat exchanger best way to protect farm animals in livestock buildings against the effects of climate change

24 Nov 2017, 1:48 pm
Without countermeasures, climate change will negatively impact animals in pig and poultry production. Beside the health and wellbeing of the animals, heat stress also affects performance and, as a result, profitability. As the animals are predominantly kept in confined livestock buildings equipped with mechanical ventilation systems, researchers examined the inlet air temperature of several air cooling systems. The best solution, they found, is the use of the earth for heat storage via an earth-air heat exchanger (EAHE). An EAHE cools in the summer, and warms up the inlet air during wintertime.

150 years of snake collections: Data bank proves rich snake diversity in the neotropics

24 Nov 2017, 1:47 pm
An extensive database constructed for snakes of the American tropics has now been released by researchers. This database is made up of museum collections from the past 150 years and demonstrates that some Neotropical regions, such as the Cerrado in the central Brazil, contain a disproportionately high diversity. Furthermore, some other diverse regions are disproportionally under sampled, such as the Amazon.

Flies could help to monitor disease outbreaks by acting as 'autonomous bionic drones' suggest scientists

24 Nov 2017, 1:47 pm
Swarms of flies can be used to help monitor disease outbreaks, suggest scientists. This follows their research that shows how whole communities of bacteria – known as a microbiome – can “hitch a ride” on common carrion flies and can be transferred to any surface where the flies land. 

Scientists develop artificial photosynthesis device for greener ethylene production

24 Nov 2017, 1:47 pm
A newly developed device could reduce the carbon footprint of ethylene production, report scientists.

Small but distinct differences among species mark evolution of human brain

24 Nov 2017, 1:43 pm
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new study has found.

World's smallest tape recorder is built from microbes

24 Nov 2017, 1:43 pm
Through a few clever molecular hacks, researchers have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring.

How badly do you want something? Babies can tell

24 Nov 2017, 1:43 pm
Babies as young as 10 months can assess how much someone values a particular goal by observing how hard they are willing to work to achieve it, according to a new study. This ability requires integrating information about both the costs of obtaining a goal and the benefit gained by the person seeking it, suggesting that babies acquire very early an intuition about how people make decisions.

Physicists develop faster way to make Bose-Einstein condensates

24 Nov 2017, 1:43 pm
Physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms. The team used a new process of laser cooling to cool a cloud of rubidium atoms all the way from room temperature to 1 microkelvin, or less than one-millionth of a degree above absolute zero.

The world needs to rethink the value of water

24 Nov 2017, 1:43 pm
New research highlights the accelerating pressure on measuring, monitoring and managing water locally and globally. A new four-part framework is proposed to value water for sustainable development to guide better policy and practice.

New species can develop in as little as two generations, Galapagos study finds

24 Nov 2017, 1:43 pm
A study of Darwin's finches, which live on the Galapagos Islands in the Pacific Ocean, has revealed direct genetic evidence that new species can arise in just two generations.

To address hunger effectively, first check the weather, says new study

24 Nov 2017, 1:43 pm
Understanding the climate context is important is determining how to best respond to food insecurity, according to a study of nearly 2,000 smallholder farms in Africa and Asia. Rainfall patterns determined whether financial supports or agricultural inputs or practices were the most effective intervention.
