Indian wolf among world’s most endangered and distinct wolves      (via sciencedaily.com) 

The Indian wolf could be far more endangered than previously recognized, say first scientists to sequence its genome. Indian wolves could also represent the most ancient surviving lineage of wolves.

Prehistoric climate change repeatedly channelled human migrations across Arabia      (via sciencedaily.com) 

Researchers have discovered archaeological sites in the Nefud Desert of Saudi Arabia associated with the remains of ancient lakes formed when periods of increased rainfall transformed the region into grassland. The researchers found that early humans spread into the region during each 'Green Arabia' phase, each bringing a different kind of material culture. The new research establishes northern Arabia as a crucial migration route and a crossroads for early humans.

Statistics say large pandemics are more likely than we thought      (via sciencedaily.com) 

The COVID-19 pandemic may be the deadliest viral outbreak the world has seen in more than a century. But statistically, such extreme events aren't as rare as we may think, asserts a new analysis of novel disease outbreaks over the past 400 years. A newly assembled record of past outbreaks was used to estimate the probability of a pandemic with similar impact to COVID-19 is about 2 percent in any year. And that probability is growing.

Researchers discover fresh water in the Mediterranean Sea      (via sciencedaily.com) 

There is enough water on our planet, but by far the largest part is salt water that is unsuitable as drinking water. Therefore, especially in dry regions of the earth, the search for new freshwater resources is very active. An international team of researchers has now discovered strong evidence of a groundwater deposit off the coast of Malta.

City-living bees benefit most from specific types of urban ‘greening’      (via sciencedaily.com) 

Converting vacant urban lots into greenspaces can reduce blight and improve neighborhoods, and new research shows that certain types of such post-industrial reclamation efforts offer the added bonus of benefiting bees.

Cancer: Information theory to fight resistance to treatments      (via sciencedaily.com) 

A major challenge in cancer therapy is the adaptive response of cancer cells to targeted therapies. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. A team has used information theory, in order to objectify in vivo the molecular regulations at play in the mechanisms of the adaptive response and their modulation by a therapeutic combination.

Solving a long-standing mystery about the desert's rock art canvas      (via sciencedaily.com) 

Petroglyphs are carved in a material called rock varnish, the origins of which have been debated for years. Now, scientists argue it's the result of bacteria and an adaptation that protects them from the desert sun's harsh rays.

More intense and frequent thunderstorms linked to global climate variability      (via sciencedaily.com) 

Large thunderstorms in the Southern Great Plains of the U.S. are some of the strongest on Earth. In recent years, these storms have increased in frequency and intensity, and new research shows that these shifts are linked to climate variability.

Butterflies regularly cross the Sahara in longest-known insect migration      (via sciencedaily.com) 

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.

Fungal spores from 250-year-old collections given new lease of life      (via sciencedaily.com) 

The biological and historical diversity in museum collections is staggering, with specimens collected across centuries by some of the most famous scientists in history. In a new study, researchers successfully revived museal fungal specimens that were more than 250 years old and used the live cultures for whole genome sequencing and physiological experiments.

Sick bats also employ 'social distancing' which prevents the outbreak of epidemics, study suggests      (via sciencedaily.com) 

In a new study, researchers demonstrate that sick bats, just like ill humans, prefer to stay away from their communities, probably as a means for recovery, and possibly also as a measure for protecting others.

Does cold wildfire smoke contribute to water repellent soils in burned areas?      (via sciencedaily.com)     Original source 

After a wildfire, soils in burned areas often become water repellent, leading to increased erosion and flooding after rainfall events - a phenomenon that many scientists have attributed to smoke and heat-induced changes in soil chemistry. But this post-fire water repellency may also be caused by wildfire smoke in the absence of heat, according to a new article.

Scientific software - Quality not always good      (via sciencedaily.com) 

Computational tools are indispensable in almost all scientific disciplines. Especially in cases where large amounts of research data are generated and need to be quickly processed, reliable, carefully developed software is crucial for analyzing and correctly interpreting such data. Nevertheless, scientific software can have quality quality deficiencies. To evaluate software quality in an automated way, computer scientists have designed the SoftWipe tool.
