Killer yeasts may help remedy a craft beer brewing bother

Sciencedaily.com 

Diastatic yeasts can spoil craft beer through hyperattenuation, which boosts the alcohol content and causes bottles to explode. Killer toxins, which are produced by other yeast strains, hint at a remedy.

Photosynthesis: A glimpse into the chloroplast workshop

Sciencedaily.com 

Photosynthesis takes place before our eyes every day in every single little green leaf -- yet the details of the complex process have not yet been fully understood. A research team has unraveled another piece of the puzzle. The team analyzed how the protein D1, which is vital for photosynthesis, is constructed and developed a new in-vitro technique for this purpose. It turned out that around 140 proteins are presumably involved in the process, some of which were previously undescribed.

In Every U.S. State, at Least 1 in 5 People Is Now Obese

Drugs.com 

THURSDAY, Sept. 12, 2024 -- Statistics from 2023 on U.S. obesity rates bring no good news: In every state in the nation, 1 in every 5 people is now obese, the new tally shows.In 2013, not one state had an adult obesity rate topping 35%, but 10...

Impact of climate change on agriculture suggests even greater challenges to the environment, global food supply and public health

Sciencedaily.com 

A sweeping global research review of the links between climate and agriculture reveals the likelihood of an emergent feedback loop whereby, as climate change puts more pressure on the global food supply, agriculture will, by necessity, adopt practices that may exacerbate its environmental impact. The paper also identifies new agricultural practices that have the potential to increase efficiency and stabilize our food supply in the decades to come.

NASA's Webb peers into the extreme outer galaxy

Sciencedaily.com 

Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison, Earth is approximately 26,000 light-years from the center.)

PSG ready to try 'legal forum' after Mbappé refuses mediation in wage dispute

France24.com (en) 

Footballer Kylian Mbappé's former club Paris Saint-Germain (PSG) said Thursday that a dispute over €55 million in what the star player says are unpaid wages could now be settled in a “legal forum”. Mbappé rejected a mediation process proposed by the French football league’s governing body to settle the matter.

Team unravels regulatory mechanism that prevents stem cell differentiation and maintains gender balance in vascular plants

Sciencedaily.com 

Plant scientists have identified a protein that plays a previously unknown role in controlling cell differentiation and determining gender in vascular plants, using a fern model. The discovery provides new insights into the stem cell-proliferation process that ensures the species reproduction and survival by preventing all offspring from developing as males.

Understudied protein blobs have global effects on cell biochemistry

Sciencedaily.com 

Researchers have shown that the formation of biological condensates affects cellular activity far beyond their immediate vicinity. The results show that they may be a previously missing mechanism by which cells modulate their internal electrochemistry. And those internal controls, in turn, affect the cellular membrane, which allows these unassuming blobs to affect global traits and outcomes such as resistance to antibiotics.

Using a molecular scissors to improve CAR-T cell therapy

Sciencedaily.com 

Researchers mined the molecular foundations of cancer and uncovered a new reason chimeric antigen receptor (CAR-T cell therapy) fails in some patients. This discovery has fueled new strategies that incorporate antibodies and gene editing to improve the outcome of this breakthrough treatment for patients.

Quantum researchers cause controlled 'wobble' in the nucleus of a single atom

Sciencedaily.com 

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of a scanning tunneling microscope. The research offers prospects for storing quantum information inside the nucleus, where it is safe from external disturbances.

No benefits from 24-hour compared with 15-hour oxygen therapy

Sciencedaily.com 

There were no differences in quality of life, symptoms, hospital admissions or mortality between a group of patients with pulmonary disease and low oxygen levels in the blood that received oxygen therapy at home for 24 hours a day, and a group that received the same therapy for 15 hours a day, according to a new study.

Azerbaijan – Situation of Théo Clerc (12 Sep. 2024)

Diplomatie.gouv.fr (en) 

France denounces the arbitrary and openly discriminatory treatment that our compatriot Théo Clerc has suffered in Azerbaijan. On September 10, Théo Clerc was sentenced by an Azerbaijani court to three years in prison for painting graffiti in the metro, while his two codefendants, who were accused of the exact same offense but hold a different nationality, were simply fined. As soon as our compatriot was arrested this past April, the French Embassy in Baku made contact with the relevant (…)
