  08-09-2021 22:44
  
  Nearly 60% of both oil and fossil methane gas and almost 90% of coal must remain in the ground by 2050 in order to keep global warming below 1.5° C, finds a study by UCL researchers.

• Megaprojects and the 'need for speed': How political indecision affects timelines of large infrastructure investments

  08-09-2021 22:32
  
  Building a new transit line or a highway almost always takes longer than initially planned. A new study suggests that the biggest contributor to such delays isn't necessarily the design, planning or even construction phases. Instead, it's the time required for local or provincial authorities to decide what exactly they want to build.

• Exploring the genetic ma(i)ze: Functional genomics can help molecular breeding of maize

  08-09-2021 22:25
  
  For centuries, the vast physical diversity of maize, the most popular cereal grain crop globally, has fascinated biologists and plant breeders alike. Early breeders selected the maize variants with good, preferrable traits and propagated them for a long time to develop "true breeding" or inbred lines that show the same favorable features, for instance, the desired kernel color or size, for generations. Because of scientific advances, it is now well known that these trait variations are linked wi

• Scientists investigate macrocyclic peptides as new drug templates

  08-09-2021 21:53
  
  Thanks to our understanding of molecular biology, we have made tremendous progress in medicine, with scientists shedding light on the molecular mechanisms of several diseases. However, despite knowing how these diseases occur and develop within cells, some remain untreatable due to the inability of currently available drugs to reach their targets. One such example of an unreachable drug target is "protein-protein interactions (PPIs)" that occur inside cells. Most drugs cannot interfere with PPIs

  More than half of the U.S. population lives in coastal watershed counties or parishes. Coastal communities along the Gulf of Mexico are among the most heavily populated—also a region where high concentrations of energy resources have made it a national hub for many large-scale carbon-to-capture storage facilities.

• Scientists see evidence of first-order phase change in nuclear matter

  08-09-2021 21:39
  
  New evidence suggests that protons and neutrons go through a "first-order" phase transition—a kind of stop-and-go change in temperature—when they "melt." This is similar to how ice melts: Energy first increases the temperature, and then, during the transition, the temperature stays steady while the energy transforms a solid to a liquid. Only when all the molecules are liquid can the temperature increase again. With protons and neutrons, the melted state is a soup of quarks and gluons

• Researchers discover how plants can respond to threats

  08-09-2021 21:29
  Plants are constantly exposed to adverse environmental influences and attacks, for example from pest infestation. An international team of researchers led by Heinrich Heine University Düsseldorf (HHU) has now described a central part of the signal mechanism used by plants to respond to threats and thus initiate a defense response in unaffected parts of the plant. In the current edition of the journal Science Advances, they describe the role played by the protein MSL10, among others.

  Decision-making that overrides one's personal views and self-interests, also known as bias suppression, is often touted as an essential institutional objective. Accountability is a common strategy for discouraging stubborn biases. However, even within the most well-intentioned organizations, efforts to counteract biases tend to wane over time.

  Most people would like to flash a smile of pearly whites, but over time teeth can become stained by foods, beverages and some medications. Unfortunately, the high levels of hydrogen peroxide in dentists' bleaching treatments can damage enamel and cause tooth sensitivity and gum irritation. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a gel that, when exposed to near infrared (NIR) light, safely whitens teeth without the burn.
