Differences in malaria clearance between males and females

Science Daily - 27/10/2020
Females are able to clear asymptomatic malaria infections at a faster rate than their male counterparts, says a new study.

Biomarkers could be used in a quick, inexpensive COVID-19 blood screening tool

Science Daily - 27/10/2020
A new study suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites -- small molecules broken down in the human body through the process of metabolism. Three specific metabolites identified in this study could act as biomarkers and one day be measured through an inexpensive blood test to quickly screen patients for the disease and predict which patients will become most critically ill.

Species loss affects basis of life of humans

Science Daily - 27/10/2020
Current species loss also affects our food, water supply, building materials and energy sources. This is confirmed by one of the biggest biodiversity experiments. Researchers found that ecosystem functions cannot only be predicted from the properties of plants, but that the entire complexity of biotic and abiotic interactions has to be considered.

For vampire bats, social distancing while sick comes naturally

Science Daily - 27/10/2020
New research shows that when vampire bats feel sick, they socially distance themselves from groupmates in their roost -- no public health guidance required.

Geologists simulate soil conditions to help grow plants on Mars

Science Daily - 27/10/2020
Humankind's next giant step may be onto Mars. But before those missions can begin, scientists need to make scores of breakthrough advances, including learning how to grow crops on the red planet.

Ultraheavy precision polymers

Science Daily - 27/10/2020
An environmentally friendly and sustainable synthesis of 'heavyweight' polymers with very narrow molecular weight distributions is an important concept in modern polymer chemistry. Thanks to a new photoenzymatic process, researchers have been able to increase the range of possible monomers. The researchers were able to obtain well-defined linear and star-shaped polymers with ultrahigh molecular weights.

Theoreticians show which quantum systems are suitable for quantum simulations

Science Daily - 27/10/2020
Researchers have shown a way to simulate the quantum physical properties of complex solid state systems. This is done with the help of complex solid state systems that can be studied experimentally.

New tactic to stop the growth of a deadly brain cancer

Science Daily - 27/10/2020
Scientists have discovered a way to stop the growth of glioblastoma, the deadliest form of brain cancer. The finding provides a new tactic in the war against cancer that involves reprogramming the immune system to do what it does best - fight the tumor instead of fueling it.

Cancer's dangerous renovations to our chromosomes revealed

Science Daily - 27/10/2020
Cancer remodels the architecture of our chromosomes so the disease can take hold and spread, new research reveals.

Scientists discover how a common mutation leads to 'night owl' sleep disorder

Science Daily - 27/10/2020
People with delayed sleep phase disorder are unable to fall asleep until late at night (often after 2 a.m.) and have difficulty getting up in the morning. In 2017, scientists discovered a surprisingly common mutation that causes this sleep disorder by altering a key component of the biological clock that maintains the body's daily rhythms. Now, a new study reveals the molecular mechanisms involved and point the way toward potential treatments.

Langerhans cells are up to the job, they just need a chance

Science Daily - 27/10/2020
Researchers found that Langerhans cells (LCs) play a crucial role in mucocutaneous acute guest-versus-host disease (aGVHD). Their experiments in mice showed that when the LCs of a recipient were depleted, the formation of mucocutaneous lesions was enhanced because the infiltration of CD8+ T cells was inhibited. Their findings have significant implications for improving blood stem cell transplantation treatments and clinical outcomes for patients.

Can individual differences be detected in same-shaped pottery vessels by unknown craftsmen?

Science Daily - 27/10/2020
Can quantitative differences be used to identify individual potters who make traditional, fixed-shape vessels that have been made in the same way for generations? Researchers discovered that there are clear variations between individuals in the formation process and hand movements used.

Back to the future of climate

Science Daily - 27/10/2020
Hot and humid: Using minerals from ancient soils, researchers are reconstructing the climate that prevailed on Earth some 55 million years ago. Their findings will help them to better assess how our climate might look in the future.

Small mussels in the Baltic are getting even smaller

Science Daily - 27/10/2020
Blue mussels in the Baltic Sea are getting smaller with time but bigger in numbers, according to a new study. Analyzing data from the last 24 years, the main reason for this appears to be changes in food quality. The type of phytoplankton that is available for blue mussels to eat can in turn be linked to our changing climate.

Large tides may have driven evolution of fish towards life on land

Science Daily - 27/10/2020
Big tidal ranges some 400 million years ago may have initiated the evolution of bony fish and land vertebrates. This theory is now supported by researchers who, for the first time, have used established mathematical models to simulate tides on Earth during this period.

Over 80 percent of COVID-19 patients have vitamin D deficiency, study finds

Science Daily - 27/10/2020
Over 80 percent of 200 COVID-19 patients in a hospital in Spain have vitamin D deficiency, according to a new study.

'White matter lesion' mapping tool identifies early signs of dementia

Science Daily - 27/10/2020
A new tool for analyzing tissue damage seen on MRI brain scans can detect with more than 70% accuracy early signs of cognitive decline, new research shows.

IIT-G develops low-cost tech to produce anti-ageing compounds

The Hindu:Science - 27/10/2020
Patented by a professor and a student, membrane technology uses a wide range of farm resources, including citrus fruits, berries, pulses, tea and onions

Types of heart damage experienced by COVID-19 patients identified

The Hindu:Science - 27/10/2020
The researchers assessed the heart scans of 305 adult patients

Lilly antibody drug fails in a COVID-19 study; others go on

The Hindu:Science - 27/10/2020
The National Institute of Allergy and Infectious Diseases said a closer look did not verify a safety problem but found a low chance that the drug would prove helpful for hospitalised patients.
