A new mathematical language for biological networks      (via sciencedaily.com)     Original source 

Researchers are presenting a novel concept for the mathematical modeling of genetic interactions in biological systems. The team has successfully identified master regulators within the context of an entire genetic network. The research results provide a coherent theoretical framework for analyzing biological networks.

Scientists engineer plant microbiome to protect crops against disease      (via sciencedaily.com)     Original source 

Scientists have engineered the microbiome of plants for the first time, boosting the prevalence of 'good' bacteria that protect the plant from disease. The findings could substantially reduce the need for environmentally destructive pesticides.

Why are bees making less honey? Study reveals clues in five decades of data      (via sciencedaily.com)     Original source 

Honey yields in the U.S. have been declining since the 1990s, with honey producers and scientists unsure why, but a new study has uncovered clues in the mystery of the missing honey.

Researchers improve seed nitrogen content by reducing plant chlorophyll levels      (via sciencedaily.com)     Original source 

Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.

Early primates likely lived in pairs      (via sciencedaily.com)     Original source 

Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.

Electronic 'soil' enhances crop growth      (via sciencedaily.com)     Original source 

Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. Researchers have now developed an electrically conductive 'soil' for soil-less cultivation, known as hydroponics.

Discovery: Plants use 'Trojan horse' to fight mold invasions      (via sciencedaily.com)     Original source 

Scientists have discovered that plants send tiny, innocuous-seeming lipid 'bubbles' filled with RNA across enemy lines, into the cells of the aggressive mold. Once inside, different types of RNA come out to suppress the infectious cells that sucked them in.

Common insect species are suffering the biggest losses      (via sciencedaily.com)     Original source 

Insect decline is being driven by losses among the locally more common species, according to a new study. The meta-analysis of 923 locations around the world notes two significant trends: 1) the species with the most individuals (the highest abundance) are disproportionately decreasing in number, and 2) no other species have increased to the high numbers previously seen. This likely explains the frequent observation that there are fewer insects around now than ten, twenty, or thirty years ago.

Using AI, researchers identify a new class of antibiotic candidates      (via sciencedaily.com)     Original source 

Using artificial intelligence, researchers discovered a class of compounds that can kill methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant bacterium that causes more than 10,000 deaths in the U.S. each year.

Wildflowers increasingly doing without insect pollinators      (via sciencedaily.com)     Original source 

Scientists have discovered that flowering plants growing in farmland are increasingly doing without insect pollinators. As reproduction becomes more difficult for them in an environment depleted in pollinating insects, the plants are evolving towards self-fertilization.

Research offers a reason why diversity in plant species causes higher farming yield, solving 'a bit of a mystery'      (via sciencedaily.com)     Original source 

A study appearing in Nature Communications based on field and greenhouse experiments at the University of Kansas shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species: Soil pathogens harmful to plants have a harder time thriving. While crop rotation and other farming and gardening practices long have reflected benefits of a mix of plants, the new research puts hard data to one important mechanism underpinning the observation: the numbers of microorganisms in the soil that eat plants.

Genetics of host plants determine what microorganisms they attract      (via sciencedaily.com)     Original source 

Plants often develop communities with microorganisms in their roots, which influences plant health and development. Although the recruitment of these microbes is dictated by several factors, it is unclear whether the genetic variation in the host plants plays a role.

Study uncovers major hidden human-driven bird extinctions      (via sciencedaily.com)     Original source 

Humans have wiped out around 1,400 bird species -- twice as many as previously thought -- with major implications for the ongoing biodiversity crisis, a new study has found. The estimated extinctions would mean almost 12 per cent of bird species have died out over modern human history, since the Late Pleistocene around 130,000 years ago, with the vast majority of them becoming extinct directly or indirectly due to human activity.

AI's memory-forming mechanism found to be strikingly similar to that of the brain      (via sciencedaily.com)     Original source 

An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
