Women who experience depression during pregnancy or after birth have higher risk of cardiovascular disease

Science Daily - 20/06/2024
Women diagnosed with perinatal depression are more likely to develop cardiovascular disease in the following 20 years compared to women who have given birth without experiencing perinatal depression. The study is the first of its kind to look at cardiovascular health after perinatal depression and included data on around 600,000 women. It found the strongest links with risks of high blood pressure, ischemic heart disease and heart failure.

A new tuberculosis vaccine candidate recombinant protein with additional post-translational modifications occurring in Mycobacterium tuberculosis cells

Science Daily - 20/06/2024
Tuberculosis is a serious health threat, and the efficacy of the BCG vaccine against tuberculosis diminishes in adulthood, making booster vaccines a realistic option. Mycobacterial DNA-binding protein 1 (MDP1), a protein found in Mycobacterium tuberculosis, elicits higher protective IFN-gamma responses in individuals who suppress tuberculosis, thus making it a vaccine candidate.

Unlocking heart health: Advancing noninvasive monitoring in chimpanzees

Science Daily - 20/06/2024
Measuring the heart rate of great apes in captivity is essential for both health management and animal studies. However, existing most methods are either invasive or inaccurate. Now, researchers have investigated the potential of using millimeter-wave radar technology to estimate heart rate from subtle body movements in chimpanzees. Their efforts will hopefully pave the way to better practices and techniques for monitoring heart rates in wild and captive primates.

Blessing in disguise: Mycoviruses enhance fungicide effectiveness against plant pathogens

Science Daily - 20/06/2024
Researchers discovered that mycoviruses, or oomycete viruses, can increase the sensitivity of plant pathogenic oomycete to fungicides like metalaxyl. Their findings suggest greater potential for mycoviruses in biocontrol and contributing to sustainable agriculture.

Transforming inexpensive quinolines into complex drug candidates

Science Daily - 20/06/2024
An innovative synthesis strategy opened up the way to 2D/3D fused frameworks using inexpensive quinolines as feedstock, report scientists. By leveraging a light-sensitive borate intermediate, the scientists could transform quinoline derivatives into a great variety of 2D/3D fused frameworks in a straightforward and cost-effective manner. Their findings are expected to enable the synthesis of highly customizable drug candidates.

More effective cancer treatment with iontronic pump

Science Daily - 20/06/2024
When low doses of cancer drugs are administered continuously near malignant brain tumors using so-called iontronic technology, cancer cell growth drastically decreases. Researchers demonstrated this in experiments with bird embryos. The results are one step closer to new types of effective treatments for severe cancer forms.

Interaction with insects accelerates plant evolution

Science Daily - 20/06/2024
Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

A railroad of cells

Science Daily - 20/06/2024
Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach now shows how they do this and how they interact with each other.

Much of the Nord Stream gas remained in the sea

Science Daily - 20/06/2024
Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.

New technology provides electrifying insights into how catalysts work at the atomic level

Science Daily - 20/06/2024
A team has invented a technique to study electrochemical processes at the atomic level with unprecedented resolution. They have already used it to discover a surprising phenomena in a popular catalyst material and plan to apply their technology to studying a wide variety of electrochemical systems including batteries, fuel cells, and solar fuel generators. The insights could lead to more efficient and durable devices.

Researchers create new class of materials called 'glassy gels'

Science Daily - 20/06/2024
Researchers have created a new class of materials called 'glassy gels' that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.

Tabulae Paralytica: Mapping the biology of spinal cord injury in unprecedented detail

Science Daily - 20/06/2024
Scientists have achieved a significant research milestone in the field of spinal cord injuries -- mapping out the cellular and molecular dynamics of paralysis in unprecedented detail with their open-source project 'Tabulae Paralytica'. Gr goire Courtine and his team have integrated cutting-edge cell and molecular mapping technologies with artificial intelligence to chart the complex molecular processes that unfold in each cell after spinal cord injuries (SCI). This seminal work not only identifies a specific set of neurons and genes that plays a key role for recovery but also proposes a successful gene therapy derived from its discoveries.

When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change

Science Daily - 20/06/2024
Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.

India getting close to developing gene therapy for sickle cell disease, say officials

The Hindu:Science - 19/06/2024
The prevalence rate of this genetic blood disorder is high among the Scheduled Tribes in the country

Union Minister Suresh Gopi meets ISRO officials in Bengaluru 

The Hindu:Science - 19/06/2024
In the light of increasing incidents of extreme weather events across India, the Minister expressed an urgent need to evaluate the worst-case flood scenario linked to these dams

Ancient genomes reveal legacies of human sacrifice and medieval epidemics

The Hindu:Science - 19/06/2024
Scientists have used archaeogenetics and evolutionary medicine to bring to light some of the inner lives and beliefs of the Mayan people

Catalytic boost for cheaper biodiesel production

The Hindu:Science - 19/06/2024
A global team comprising Assam-based scientists developed a superhydrophobic catalyst that can cut biodiesel cost from about $1.2 now to 37 cents per litre

Mirror-image chemicals may revolutionize drug delivery

Science Daily - 19/06/2024
More than 130 years after cyclodextrins were first discovered and reported, a team of scientists has created chemical mirror images of these complex carbohydrates in the laboratory. This discovery may revolutionize how medications are delivered to patients.

Is coffee good for you or bad for you?
