Breakthrough could lead to early detection of pregnancy complications

Science Daily - 13/05/2021
Researchers have found a way to study uterine fluid in the lab, thereby avoiding invasive procedures during pregnancy, while at the same time developing a potential model for using precision medicine to improve pregnancy outcomes.

Backyard chickens, rabbits, soybeans can meet household protein demand

Science Daily - 13/05/2021
In 2020, stores sold out of garden seed, coops and rabbit cages. Meat shortages led many to wonder what to eat for protein when supply chains are disrupted and some people turned to gathering eggs, raising animals and growing their own food. A team assessed backyard protein sources: They looked at how a typical household with a typical backyard can raise chickens, rabbits or soybeans to meet its protein needs.

Researchers identify target for senolytic drugs

Science Daily - 13/05/2021
Researchers found that senescent immune cells are the most dangerous type of senescent cell.

COVID-19 is not influenza, but it offers lessons on beating it, say researchers

Science Daily - 13/05/2021
A study of the 2020 influenza figures from Canada, the United States, Australia and Brazil shows that there is a clear relationship between COVID-mitigation measures such as hand-washing, masking and social distancing and the spread of the annual flu, researchers report. They write that these preventive measures all but eliminated the flu in countries where it can kill tens of thousands of people a year, even as cases of COVID-19 soared.

New ebolavirus vaccine design seeks to drive stronger antibody defense

Science Daily - 13/05/2021
Scientists have unveiled a new Ebola virus vaccine design, which they say has several advantages over standard vaccine approaches for Ebola and related viruses that continue to threaten global health. In the new design copies of the Ebola virus outer spike protein, known as the glycoprotein, are tethered to the surface of a spherical carrier particle.

Symbiotic bacteria in root cells may be key to producing better crops

Science Daily - 13/05/2021
A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.

Study reveals structure of key receptors involved in memory and learning

Science Daily - 13/05/2021
Scientists have for the first time revealed the structure surrounding important receptors in the brain's hippocampus, the seat of memory and learning. The new study focuses on the organization and function of glutamate receptors, a type of neurotransmitter receptor involved in sensing signals between nerve cells in the hippocampus region of the brain. The study reveals the molecular structure of three major complexes of glutamate receptors in the hippocampus.

The triple threat of coronavirus

Science Daily - 13/05/2021
Immense research efforts are invested in figuring out how the virus manages to mount an effective invasion while throwing the immune system off course. A new study reveals a multipronged strategy that the virus employs to ensure its quick and efficient replication, while avoiding detection by the immune system.

Bears that mark more trees may be more successful in mating

Science Daily - 13/05/2021
Brown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a new study. The results suggest there might be a fitness component to the poorly understood behavior.

Study finds six degrees celsius cooling on land during the last Ice Age

Science Daily - 13/05/2021
Researchers show that prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth's climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates.

Interactive typeface for digital text

Science Daily - 13/05/2021
Researchers have developed a computer font that adapts its appearance based on the user's interaction with the text. ''AdaptiFont'' measures a user's reading speed and interactively changes the font's shape seamlessly and continuously to allow the user to read text more easily. By employing an artificial intelligence algorithm, new personalized fonts are generated on the fly in such a way that they increase an individual reader's reading speed.

Scientists design new drug compound to stop malaria in its tracks

Science Daily - 13/05/2021
Researchers have designed a drug-like compound which effectively blocks a critical step in the malaria parasite life cycle and are working to develop this compound into a potential first of its kind malaria treatment.

Mitochondrial enzyme found to block cell death pathway points to new cancer treatment strategy

Science Daily - 13/05/2021
Researchers have discovered a new role for the DHODH enzyme in blocking a form of cell death called ferroptosis. Preclinical findings suggest that targeting DHODH could restore cell death and inhibit tumor growth.

Mechanism deciphered: How organic acids are formed in the atmosphere

Science Daily - 13/05/2021
The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these impact the growth of clouds and pH of rainwater. But the chemical processes behind the formation of formic acid were not well understood. Researchers have now succeeded in filling this gap.

Scientists create a new type of intelligent material

Science Daily - 13/05/2021
Researchers have created a new class of intelligent materials. It has the structure of a two-dimensional (2D) material, but behaves like an electrolyte - and could be a new way to deliver drugs within the body.

Only 17 percent of free-flowing rivers are protected

Science Daily - 12/05/2021
The research demonstrates that biodiversity commitments will be key to global freshwater protection.

Female lawyers more likely to report stress, risky drinking than male lawyers

Science Daily - 12/05/2021
Work-related factors impact the high rates of stress, risky drinking, and attrition in lawyers differently depending on gender, according to a new study.

Genetic risk of heart disease may be due to low Omega 3-linked biomarker

Science Daily - 12/05/2021
People who are genetically more likely to suffer from cardiovascular diseases may benefit from boosting a biomarker found in fish oils, a new study suggests.

Who fought in the ancient Greek Battles of Himera? Chemical evidence provides answers

Science Daily - 12/05/2021
Geochemical evidence reveals that armies in the Battles of Himera were a mixture of locals and outsiders, according to a new study. These data contradict certain claims made in historical accounts by ancient Greek writers.

Ancient Easter Island communities offer insights for successful life in isolation

Science Daily - 12/05/2021
Anthropologists explore how complex community patterns in Easter Island helped the isolated island survive from its settlement in the 12th to 13th century until European contact.
