Article Synopsis
  • The study investigates the role of a master regulator gene in the development of excitatory neurons, specifically focusing on its function in cerebellar granule neuron progenitors (GNPs).
  • Researchers found that dysfunction of this gene in GNPs reduced their proliferation and led to various cerebellar abnormalities, including hypoplasia and imbalances in neuron ratios.
  • The findings suggest that deletion of this gene during early development can cause autism-like behaviors in mice and highlight uncharacterized gene variants associated with autism spectrum disorder in humans.

We present a method for predicting hyperchaotic time series using a complex network-based forecasting model. We first construct a network from a given time series, which serves as a coarse-grained representation of the underlying attractor. This network facilitates multistep forecasting by capturing the local nonlinearity of the dynamics and offers superior accuracy over more extended periods than traditional methods.

Article Synopsis
  • Researchers developed a transformation system using Agrobacterium to study gene function in grass pea (Lathyrus sativus), which is known for its protein-rich seeds but has limitations due to a neurotoxin present in the plant.
  • They focused on the role of an enzyme called oxalyl-CoA synthetase (OCS) in oxalate metabolism, which is crucial for understanding β-ODAP production, the neurotoxin linked to health issues.
  • Their experiments demonstrated that modifying the LsOCS gene can help manage oxalate levels without increasing toxic compound levels, suggesting that this genome editing approach can efficiently enhance desirable traits in grass pea cultivation.

In fish, as in other vertebrates, thyroid hormones (THs) act on many biological processes including growth and reproduction. Primary THs such as thyroxine (T) and triiodothyronine (T) are known for their direct action on osmoregulatory organs regulating ion osmotic homeostasis in many teleost fishes. However, it is unclear how these hormones interact with estradiol-17β (E), an ovarian hormone that regulates the development of oocytes.
