Discovery of periodic tables for molecules

titech.ac.jp
  • New model for periodic table of molecules shows promise in the field of materials design, possibly enabling scientists to create innovative functional materials.
  • The table would be 4-dimensional, arranging molecules by four parameters: groups, periods, species, and families.
  • It’s based on novel “symmetry-adapted orbital (SAO) models”, which align with known molecules and quantum-mechanical calculations.
  • Now scientists will keep expanding these tables to predict new stable molecules that could be developed.

A swifter way towards 3D-printed organs

  • Sacrificial Writing Into Functional Tissue (SWIFT) enables scientists to 3D-print organ-specific tissues viable for transplants.
  • It focuses on printing vessels necessary to support a living tissue construct with large amounts of organ building blocks.
  • This means they could be used to repair and replace organs using lab-grown versions containing the patients’ own cells.
  • Combined with recent advances in stem-cell research, this method is a big step forward for organ engineering.

Left-handed DNA found - and it changes brain structure

bbc.com
  • The first genetic components of left-handedness have been discovered.
  • Some cultures associate left-handedness with bad luck or malice, and this proves that it’s just a consequence of the developmental biology of the brain.
  • Researchers used a database of 400,000 genetic code sequences from the UK Biobank, wherein 38,000 people were left-handed.
  • Lefties have better connections between the left and right brain hemispheres, and more coordination in language-related regions.
  • This might mean that they have better verbal skills, however this study cannot prove this.

Scientists isolate drought-resistant gene in barley

theguardian.com
  • After 5 years of research, scientists have isolated a gene in barley that can help protect crops from droughts caused by climate change.
  • The gene - HvMYB1 - was isolated from 39,000 genes in barley, and proven to improve the plant’s ability to survive in rough conditions.
  • Food production is already affected by abnormally high temperatures, so this is an important step towards maintaining the global food supply.

Hundreds of extreme self-citing scientists revealed in new database

nature.com
  • Study of most-cited 100,000 researchers of the last 20 years, across 176 fields, explores excessive self-citation.
  • There is growing interest in self-citation, and the problems it may cause, in the scientific community.
  • Nobody really knows how much self-citation is enough -- in some fields its unavoidable.
  • Solving this issue is more complex than it seems, but everyone agrees that it shouldn’t be about punishing self-citers.
  • Rather, citation metrics may have become too important for making decisions about hiring, promotions, and research funding.
