A rare enzyme role change with bacterial defense system assembly      (via sciencedaily.com)     Original source 

Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.

Some icy exoplanets may have habitable oceans and geysers      (via sciencedaily.com)     Original source 

A new study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, beneath icy shells. Water from these oceans could occasionally erupt through the ice crust as geysers. The science team calculated the amount of geyser activity on these exoplanets, the first time these estimates have been made. They identified two exoplanets sufficiently close where signs of these eruptions could be observed with telescopes.

Ryugu samples illuminate terrestrial weathering effects on primitive meteorites      (via sciencedaily.com)     Original source 

Asteroids offer valuable windows into the early solar system, given that they are remnants of planetary embryos that failed to form into planets. A recent analysis of samples from Ryugu offered insights into the composition of water- and carbon-rich small bodies in the solar system.

Zika's shape-shifting machinery, and a possible vulnerability      (via sciencedaily.com)     Original source 

Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.

When is an aurora not an aurora?      (via sciencedaily.com)     Original source 

While auroras occur at high latitude, the associated phenomena Steve and the picket fence occur farther south and at lower altitude. Their emissions also differ from aurora. A physics graduate student has proposed a physical mechanism behind these emissions, and a rocket launch to test the theory. She argues that an electric field in the upper atmosphere parallel to Earth's magnetic field could explain the green picket fence spectrum and perhaps Steve and the enhanced aurora.

How immune cells recognize their enemies      (via sciencedaily.com)     Original source 

In order for immune cells to do their job, they need to know against whom they should direct their attack. Research teams a have identified new details in this process.

Scholars say it's time to declare a new epoch on the moon, the 'lunar Anthropocene'      (via sciencedaily.com)     Original source 

According to anthropologists and geologists, it's time to acknowledge humans have become the dominant force shaping the moon's environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. They argue the new epoch may have dawned in 1959 when the USSR's unmanned spacecraft Luna 2 alighted on the lunar surface.

New genes can arise from nothing      (via sciencedaily.com)     Original source 

The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.

Fungus-fighting protein could help overcome severe autoimmune disease and cancer      (via sciencedaily.com)     Original source 

A protein in the immune system programmed to protect the body from fungal infections is also responsible for exacerbating the severity of certain autoimmune diseases such as irritable bowel disease (IBS), type 1 diabetes, eczema and other chronic disorders, new research has found.  The discovery could pave the way for new and more effective drugs, without the nasty side effects of existing treatments. In addition to helping to manage severe autoimmune conditions, the breakthrough could also help treat all types of cancer.

Limitations of asteroid crater lakes as climate archives      (via sciencedaily.com)     Original source 

In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful analogues for asteroid craters on early Mars. Studying the deposits of the former lake that formed in the crater is particularly informative. These deposits have been of great interest ever since NASA began exploring Martian craters for signs of water and life on Mars.

Unlocking neutron star rotation anomalies: Insights from quantum simulation      (via sciencedaily.com)     Original source 

A collaboration between quantum physicists and astrophysicists has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research establishes a strong link between quantum mechanics and astrophysics and paves the way for quantum simulation of stellar objects from Earth.
