Computer-engineered DNA to study cell identities

Sciencedaily.com 

A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. It will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.

Summer Criterium #14 Race Report

Canberra Cycling Club 

Round 14 – the Pride Round – of the Summer Crits kicked off with perhaps the most difficult wind conditions of the season so far. A strong westerly, making its presence felt from the bottom of the track right through till well into the home straight was sure to prove a major test with splits almost an inevitability.

Smells like evolution: Fruit flies reveal surprises in chemical sensing

Sciencedaily.com 

New study reveals how gene expression shapes the diverse smelling and tasting abilities of different fly species. Most genes are surprisingly stable, but thousands have evolved to create unique olfactory landscapes. Sex differences in sensing are widespread and involve specific cell types in key tissues. The study provides insights into the evolution of sensory systems in general, with potential implications for understanding human olfaction.

Ammonia attracts the shipping industry, but researchers warn of its risks

Sciencedaily.com 

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.



Microbial division of labor produces higher biofuel yields

Sciencedaily.com 

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

Scientists 'break the mould' by creating new colors of 'blue cheese'

Sciencedaily.com 

Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.

Bullied teens' brains show chemical change associated with psychosis

Sciencedaily.com 

Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions. The finding suggests that this neurotransmitter may be a potential target for pharmaceutical interventions aimed at reducing the risk of psychotic disorders.

Study challenges the classical view of the origin of the Antarctic Circumpolar Current and warns of its vulnerability

Sciencedaily.com 

The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study has cast doubt on this theory, and has changed the understanding of how the ice sheet in Antarctic developed in the past, and what this could mean in the future as the planet's climate changes.

Researchers develop rapid test for detecting fentanyl

Sciencedaily.com 

Researchers have developed a first-of-its-kind, handheld electrochemical sensor that can accurately detect fentanyl in urine within seconds. The proof-of-concept technology can detect even trace amounts of fentanyl with 98% accuracy using a small portable device without costly and time-consuming lab analysis.

Ultra-sensitive lead detector could significantly improve water quality monitoring

Sciencedaily.com 

Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.
