A study designed to study how the immune system impacts gut bacteria - has led to the extraordinary discovery of two molecules that can not only provide profound protection in experimental models of asthma but can also substantially reduce the severity of an attack.
Neither of these molecules, one of which is already commercially available as a dietary supplement, were previously known to have an effect on asthma - and they also appear, from animal studies, to have a role in treating the respiratory illness that is prevalent, and often fatal, in people with serious COVID-19.
The researchers aim to test one of the molecules in a clinical trial in 2021 in asthmatics.
As further evidence that these two molecules ...

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces the discovery of a new polybutadiene molecule - from a material known for over a century and used to make common products like tires and shoes - that could one day advance this goal through depolymerization.
The Chirik lab reports in Nature Chemistry that during polymerization the molecule, named (1,n'-divinyl)oligocyclobutane, enchains in a repeating sequence of squares, a previously ...

Human females rely on aids like charting, test strips or wearable tech to identify periods of fertility. Some animals, like baboons, undergo obvious physical changes during ovulation. How did fertility become so hard to detect in humans?
For nearly half a century, the evolution of concealed ovulation in human females has been explained as useful for securing male partners to help raise and support children. A END ...

It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that certain head-on collisions may in fact clear the galactic nuclei of the matter which would otherwise fuel the black holes contained within.
When you think about gargantuan phenomena such as the collision of galaxies, it might be tempting to imagine it as some sort of cosmic cataclysm, with stars crashing and exploding, and destruction on an epic scale. ...

New genetic faults discovered in people with a heart condition that is sometimes inherited in families could transform the diagnosis and treatment of the hidden disease, according to research funded by the British Heart Foundation (BHF) and published in Nature Genetics.
Researchers have found a new type of genetic change in the DNA of people with hypertrophic cardiomyopathy (HCM) - a silent killer amongst families that can cause sudden death in young people due to the thickening of the heart muscle.
This ground-breaking discovery, which may be the biggest advance in our knowledge of the genetic basis of the ...

1. Key points of the work
- An emerging semiconductor for future power devices, beta-gallium oxide (β-Ga2O3), was investigated using a technique called transmission terahertz time-domain spectroscopy (THz-TDS) for the first time
- The findings on the fundamental properties of β-Ga2O3 at THz frequencies are significant to the development of this semiconductor's power electronic applications
- THz-TDS can be used as a noninvasive tool for the evaluation of electrical properties instead of conventional electrical measurements that degrade the semiconductor quality
2. Overview of the work
The β-Ga2O3 ultra-wide bandgap (UWBG) ...

Cisplatin has been used to treat cancer since the 1970s. Since then, many other platinum-containing cytostatic drugs have been developed, such as triplatinNC, a highly charged complex that contains three ligand-bridged platinum atoms. Unlike cisplatin, this drug also directly inhibits metastasis. The reason for this seems to be modulation of the geometry of a sugar component of heparan sulfate, an important component of the extracellular matrix, reports a research team in the journal Angewandte Chemie.
Heparan sulfate, a glycosaminoglycan, is a chain of ring-shaped sugar molecules. It is involved in many regulatory processes, as well as in the growth and metastasis of tumors. In order for ...

The absence of monsoon rains at the source of the Nile was the cause of migrations and the demise of entire settlements in the late Roman province of Egypt. This demographic development has been compared with environmental data for the first time by professor of ancient history, Sabine Huebner of the University of Basel - leading to a discovery of climate change and its consequences.
The oasis-like Faiyum region, roughly 130 km south-west of Cairo, was the breadbasket of the Roman Empire. Yet at the end of the third century CE, numerous formerly thriving settlements there declined and were ultimately abandoned by their inhabitants. Previous excavations and contemporary papyri have shown that problems with field irrigation were the cause. Attempts by ...

Researchers perform experiments that can add or subtract a single quantum of sound--with surprising results when applied to noisy sound fields.
Quantum mechanics tells us that physical objects can have both wave and particle properties. For instance, a single particle--or quantum--of light is known as a photon, and, in a similar fashion, a single quantum of sound is known as a phonon, which can be thought of as the smallest unit of sound energy.
A team of researchers spanning Imperial College London, University of Oxford, the Niels Bohr Institute, University ...
