Can You Lose Weight? Ask Your Microbiome

A new study from Institute for Systems Biology (ISB) reveals that the genetic capacity of the gut microbiome is strongly associated with weight loss success or failure. Microbiomes of those who lost weight had higher bacterial growth rates and were enriched in genes that divert dietary nutrients toward bacterial cell growth. In contras...

Scientists can now assemble entire genomes on their personal computers in minutes

Researchers at MIT and Institut Pasteur have created an efficient method for assembling entire genomes, including the human genome, in minutes using personal computers. This approach uses minimizer-space de Bruijn graphs to store only a small fraction of nucleotides while preserving overall genome structure, enabling faster processing ...

Taking lessons from a sea slug, study points to better hardware for artificial intelligence

A study by Purdue University and collaborators has found a way to demonstrate habituation and sensitization in nickel oxide, a quantum material that mimics the sea slug's most essential intelligence features. This discovery could lead to building hardware-based AI with improved efficiency and reduced energy consumption.

People only pay attention to new information when they want to

A new study found that people tend to listen to and believe information that supports their existing biases, rather than seeking out contradictory evidence. This phenomenon, known as motivated reasoning, can lead to the amplification of biases and the spread of misinformation in online communities and financial markets.

Clinicians say there is limited clinical guidance for how to help people lose weight after pregnancy

A new study reveals that few recommendations exist for postpartum weight loss, with a focus on diet and exercise. Researchers emphasize the importance of supporting individuals with excessive weight gain or retention during pregnancy and the postpartum period to prevent obesity-related chronic diseases.

COVID-19 antibodies persist, reduce reinfection risk for up to six months, study finds

A Michigan Medicine study found that most patients with mild COVID-19 infections produce antibodies that persist and protect them from reinfection for up to six months. Nearly 90% of participants produced spike and nucleocapsid antibody responses, and all but one had persistent antibody levels at follow-up.

What lies beneath: Volcanic secrets revealed

A University of Queensland-led study reveals that hot spot volcanoes do not produce 'pristine' magma from the melting mantle but instead filter a different melt to the surface. This new information supports the notion that detection of magma at the crust-mantle boundary could indicate an upcoming eruption.

Scientists synthesized a yellow fever drug suggested by artificial intelligence

Researchers developed a machine learning model that identified promising compounds for treating yellow fever. The team synthesized five of the most active molecules and found one with a half-maximal effective concentration of 3.2 uM, suggesting a potential new antiviral drug.

How plants sense phosphate

Scientists at the University of Bonn and IPK discover that plants use signaling molecule InsP8 as a proxy for overall phosphate status. ITPK1 enzyme plays a key role in this process, regulating phosphate sensing and mobilization. The findings have far-reaching consequences for sustainable crop production.

Fixing protein production errors lengthens lifespan

A recent study published in Cell Metabolism found that reducing naturally occurring errors in protein synthesis improves both health and lifespan. By engineering a mutation in ribosomes, researchers observed fewer protein mistakes and improved heat resistance, leading to longer lifespans in yeast, worms, and fruit flies.
