Eating crickets can be good for your gut, according to new clinical trial

Posted: 03 Aug 2018 10:46 AM PDT

A new clinical trial shows that consuming crickets can help support the growth of beneficial gut bacteria and that eating crickets is not only safe at high doses but may also reduce inflammation in the body.

Engineered genetic machinery derived from E. coli delivers new amino acids to proteins

Posted: 03 Aug 2018 09:19 AM PDT

Approximately 15 years ago, scientists first saw the potential of an engineered, bacteria-derived genetic machinery for incorporating non-canonical amino acids into proteins produced in eukaryotic cells. But the method has faced a number of technical restrictions that limited its widespread development. Researchers have developed a new method that overcomes many of the previous obstacles.

Each tropical tree species specializes in getting the nutrients it needs

Posted: 03 Aug 2018 09:19 AM PDT

Researchers looking for general patterns in the way tropical trees capture nutrients were surprised to find that every species has its own way of getting the nutrients it needs. The concept of biodiversity extends to their behavior.

Parasite infections with multiple strains are more harmful to vertebrate hosts

Posted: 03 Aug 2018 08:48 AM PDT

The incredible amount of genetic diversity in parasites means humans are often infected with multiple strains, which could make infections worse and increase the prevalence of the parasite over time.

Key gene to accelerate sugarcane growth is identified

Posted: 03 Aug 2018 08:47 AM PDT

Researchers have developed a sugarcane line with the ScGAI gene expression silenced. The modification resulted in an adequate phenotype for use in 2G ethanol production, featuring a bigger culm and more biomass.

Tropical forest seeds use three strategies to survive

Posted: 03 Aug 2018 07:33 AM PDT

From tiny banana seeds to giant coconuts, it's tough for seeds to survive in tropical soils where they are under constant attack by fungi, bacteria, insects and animals. By understanding how seeds defend themselves, tropical biologists contribute to reforestation, crop management and sustainable agriculture in the tropics.

Who owns the aquifer?

Researchers map out groundwater at stake in the wake of a court decision that bolsters Native American rights to the precious resource across an increasingly arid West.

Abandoned farmlands enrich bird communities

Posted: 03 Aug 2018 07:33 AM PDT

Abandoned farmlands hold potential for the preservation of wetland and grassland birds as rehabilitation zones.

Locusts help uncover the mysteries of smell

Posted: 03 Aug 2018 07:33 AM PDT

By looking into the brains of locusts, researchers have determined how one smell can affect another, and how a locust can recognize a smell even though its brain activity looks different depending on the context.

Even low levels of air pollution linked with serious changes in the heart, according to new UK research

Posted: 03 Aug 2018 07:33 AM PDT

Researchers have found that people exposed to air pollution levels well within UK guidelines have changes in the structure of the heart, similar to those seen in the early stages of heart failure.

The fate of Arctic mosquitoes depends on habitat and access to blood meals

Posted: 03 Aug 2018 07:33 AM PDT

The future of Arctic mosquitoes (Aedes nigripes) in western Greenland depends on aquatic habitat and access to blood meals, according to a new study. The study found that female mosquitoes carrying eggs were most abundant near ponds, especially in areas frequented by animals such as caribou, birds and the Arctic hare.

Monash scientists show that highly lethal viruses hijack cellular defences against cancer

Posted: 03 Aug 2018 07:33 AM PDT

Henipaviruses are among the deadliest known viruses and have no effective treatments. They include Hendra, lethal to humans and horses, and the Nipah virus, a serious threat in parts of Asia. Researchers have now discovered that Henipaviruses hijack a mechanism used by cells to counter DNA damage and prevent harmful mutations (important in diseases like cancer). This finding adds insight into how viruses behave, and could lead to new targets for antivirals to treat them.

Rebuilding the tree of life of freshwater macroinvertebrates in the European continent

Posted: 03 Aug 2018 07:33 AM PDT

Scientists analyzed how water macroinvertebrate species, such as beetles, mosquitos and dragonflies, evolved and diversified since their beginnings. With the analysis of the ecological features of about 6,600 European species, the researchers rebuilt the functional space they occupy.

The subtle mechanics of an avalanche -- as seen in 3D

Posted: 03 Aug 2018 07:33 AM PDT

Drawing on the fact that the snow in an avalanche can behave like both a solid and a fluid, a researcher has managed to simulate a snow slab avalanche with unrivaled precision.

Rethinking ketchup packets: New approach to slippery packaging aims to cut food waste

Posted: 03 Aug 2018 07:33 AM PDT

New research aims to cut down on waste -- and consumer frustration -- with a novel approach to creating super slippery industrial packaging. The study establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics, like those used for ketchup packets and other condiments.

How hungry bacteria sense nutrients in their environment

Posted: 03 Aug 2018 07:32 AM PDT

New research sheds light on how bacteria regulate metabolism -- a finding that could help to combat infectious diseases including tuberculosis.

Old mining techniques make a new way to recycle lithium batteries

Posted: 02 Aug 2018 04:19 PM PDT

Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries.

Heatwave and climate change having negative impact on our soil say experts

Posted: 02 Aug 2018 07:23 AM PDT

The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realized say scientists. That's because organisms in soil are highly diverse and are responsible not only for producing the soil we need to grow crops, but also provide humans with many other benefits, such as cleaning water and regulating greenhouse gas emissions.
