Using 'big data' to fight flu

A recent study identified 20 previously unknown host molecules that enable influenza A viruses to replicate and spread. Blocking these host proteins can inhibit viral growth and slow disease progression in mice. The researchers developed a public web portal to facilitate drug development and analysis of host-protein interactions.

How skates and rays got their wings

A new study by scientists from the University of Chicago reveals that the unique pectoral fins of skates and rays are built using repurposed genes from typical limb-development pathways. The findings provide insight into the genetic mechanisms behind the evolution and diversification of vertebrate appendages.

It's all about polarity

Asymmetric cell division occurs when endosomes, containing signalling molecules, are distributed unevenly between daughter cells. The central spindle, a scaffold structure composed of microtubules, plays a crucial role in dispatching this information.

TET proteins help maintain genome integrity

A recent study published in Nature Communications reveals that TET protein loss of function leads to rapid development of malignant cancer. The research found that mice lacking both Tet2 and Tet3 developed aggressive myeloid leukemia, highlighting the importance of TET proteins in maintaining genome stability and preventing cancer.

Plant-inspired power plants

A study by University of Pittsburgh researchers outlines a framework for developing catalysts that convert excess CO2 into liquid fuel. The catalyst's effectiveness is determined by its hydrogen adsorption energy and Lewis pair hardness, allowing for more efficient and inexpensive production.

Research looks at impact of hedge fund activism

Research found that hedge fund activism initially bolsters target companies but weakens competitors, potentially reducing innovation and consumer growth. Average investors are more likely to hold stock in competitor firms, which may face reduced investment in research and development.

On-the-go ultrahigh vacuum storage systems

Researchers developed a portable ultrahigh vacuum storage system to securely transport air-sensitive platinum metal clusters for XAFS measurements. The 'suitcase' can store up to three samples and is designed for public transportation, reducing travel time and increasing accessibility.

Eliminating food deserts may not achieve improved dietary quality in the US

A recent study suggests that eliminating food deserts may not lead to improved dietary quality in the US. Instead, initiatives like education and changes to food assistance programs can have a greater impact on reducing disparities in diet quality. The authors argue that addressing these disparities is crucial for improving public health.

What contributes to healthy living behaviors among children? It depends...

A study reveals that factors contributing to healthy living behaviors among children differ between countries, challenging the notion of a 'one-size-fits-all' approach. Short sleep duration and poor sleep quality are linked to unhealthy habits in high-income countries, while flexibility and discretionary time may play a role in low-inc...

Study points to barriers to biologic treatments for some patients with psoriasis

A new study found that black patients receiving Medicare are less likely to receive biologic therapies for moderate to severe psoriasis than white patients, while those without low-income subsidy are also at a disadvantage. Psoriasis, a chronic inflammatory disorder, has limited therapeutic options due to high costs and limited insuran...

New discoveries redefine Angkor Wat's history

The temple of Angkor Wat has been found to be significantly larger and more complex than previously believed, featuring an entire ensemble of buried 'towers' and a massive structure bounded on its south side. The discovery challenges traditional understanding of the social hierarchy of the Angkor Wat community.

Fighting liver fibrosis, the wound that never heals

The Salk Institute has identified a drug called JQ1 that prevents and reverses liver fibrosis in animals, a condition that replaces normal liver cells with scar tissue until the organ no longer works. This discovery may also treat fibrosis in other organs such as the lung, pancreas, and kidney.

If you make impulsive choices you should blame your parents -- it's genetic

A recent study found that delay discounting, the tendency to choose smaller rewards now rather than larger ones later, is strongly influenced by genetics. As individuals age, their ability to wait for larger delayed rewards improves. The study suggests that genes related to serotonin synthesis and binding may play a role in impulsivity.

One in 4 new doctors may be depressed -- and their patients may suffer because of it

A new study analyzing 50 years of research on depression in medical residency found that nearly one-third of new doctors may be depressed, with potential consequences for their patients' health. The study's findings emphasize the need for improved mental health support and strategies to prevent and treat depression among young doctors.
