Researchers trace dust grain's journey through newborn solar system
- ScienceDaily
- 21/6/21 23:41
Combining atomic-scale sample analysis and models simulating likely conditions in the nascent solar system, the study revealed clues about the origin of crystals that formed more than 4.5 billion years ago. The findings provide insights into the fundamental processes underlying the formation of planetary systems, many of which are still shrouded in mystery.
Butterflies regularly cross the Sahara in longest-known insect migration
- ScienceDaily
- 21/6/21 23:41
Wetter conditions in Sub-Saharan and North Africa at certain times of year can result in hundreds of times more Painted Lady butterflies making the 14,000 km round trip to Europe. Findings improve understanding of how insects move to other countries, including pests that destroy crops and disease-carrying species like mosquitoes.

Lead from leaded petrol persists in London air despite '90s ban
- ScienceDaily
- 21/6/21 22:05
Lead levels in London's atmosphere have dropped drastically since lead additives in petrol were phased out, and currently meet UK air quality targets. However despite this drop, airborne particles in London are still highly lead-enriched compared to natural background levels, according to new research.
'Pack ice' tectonics reveal Venus' geological secrets
- ScienceDaily
- 21/6/21 22:05
A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice.
Database of vegetation of planet Earth
- ScienceDaily
- 21/6/21 22:05
It's a treasure trove of data: the global vegetation database 'sPlotOpen' is now freely accessible. It contains balanced, representative data on vegetation from 114 countries and from all climate zones on Earth.
COVID-19 dual-antibody therapies effective against variants in animal study
- ScienceDaily
- 21/6/21 22:05
A new study suggests that many, but not all, COVID-19 therapies made from combinations of two antibodies are effective against a wide range of virus variants. Further, combination therapies appear to prevent the emergence of drug resistance.
'Flashed' nanodiamonds are just a phase
- ScienceDaily
- 21/6/21 22:05
A new 'flash' process can turn carbon black into functionalized nanodiamond and other materials. The carbon atoms evolved through several phases depending on the length of the flash.
Quantum computing: Common perovskite superfluoresces at high temperatures
- ScienceDaily
- 21/6/21 22:05
A commonly studied perovskite can superfluoresce at temperatures that are practical to achieve and at timescales long enough to make it potentially useful in quantum computing applications.
Universal mechanism of regulation in plant cells discovered
- ScienceDaily
- 21/6/21 22:05
All plant cells obtain their energy mainly from two organelles they contain - chloroplasts (responsible for photosynthesis) and mitochondria (responsible for the biochemical cycle of respiration that converts sugars into energy). However, a large number of a plant cell's genes in its mitochondria and chloroplasts can develop defects, jeopardising their function. Nevertheless, plant cells evolved...
SARS-CoV-2 infections may trigger antibody responses against multiple virus proteins
- ScienceDaily
- 21/6/21 22:05
All coronaviruses produce four primary structural proteins and multiple nonstructural proteins. However, the majority of antibody-based SARS-CoV-2 research has focused on the spike and nucleocapsid proteins. A new study suggests that immune responses may develop against other proteins produced by the SARS-CoV-2 virus.
New method developed to detect and adjust population structure in genetic summary data
- ScienceDaily
- 21/6/21 22:05
Researchers announced the development of a new method to increase the utility and equity of large genetic databases.
The Science of tsunamis
- ScienceDaily
- 21/6/21 22:05
The word 'tsunami' brings immediately to mind the havoc that can be wrought by these uniquely powerful waves. The tsunamis we hear about most often are caused by undersea earthquakes, and the waves they generate can travel at speeds of up to 250 miles per hour and reach tens of meters high when they make landfall and break. They can cause massive flooding and rapid widespread devastation in...
New method for molecular functionalization of surfaces
- ScienceDaily
- 21/6/21 22:05
An interdisciplinary team of researchers has succeeded in depositing nitrogen-containing organic molecules as a highly ordered layer on silicon. This opens up new perspectives for the development of more powerful semiconductor materials, which can be used, for example, in computers, photovoltaics or sensor technology.
