Fromdazzling Anglo - Saxon treasuretoEarth ’s constellation of " minimoons , " it ’s been a fussy calendar week for skill news show . While our own major planet has delivered its fair parcel of surprising stories , our cosmic neighbor has stolen show with its latest cheeseparing - ups .
In the last few months , NASA ’s Martian scouter have place back images ofgiant " kidney bean"-like structures , " ripples " left by ancient waterandrocks that look like spider egg . Now , gamy - resolution satellite imagery has revealedwave - like soil patterns on the Martian surfacethat intimately resemble those find on our own planet .
Wave patterns on Mars and free-floating atoms.
On Earth , these ripples tend to form on the gradient of cold mountains , where dirt block and thawing throughout the twelvemonth . It is unclear whether the same process produce these patterns on Mars , but research worker hope that canvas them will offer valuable insights into the planet ’s clime history , as well as aiding in our hunt for signs oflife on Mars .
Mysterious hilltop discovery
Archaeologists discover hundreds of metal objects up to 3,400 years old on mysterious volcanic hilltop in Hungary
High on a volcanic hill in western Hungary , archeologist haveuncovered a rarified hoard of hundred of ancient artifacts , include jewelry , military decorations and weapon system , dating from the recent Bronze Age ( 1450 to 800 B.C. ) to the former Iron Age ( 800 to 450 B.C. ) .
Today , the area around Somló is primarily recognize for its wine production . However , in the late 19th hundred local farmers and wine-colored producers began unearthing ancient artifacts , leading researchers to plunk deeper into the hilltop ’s buried secrets .
The findings signal that the brow might once have been a nates of power among the communities that once go there .
Some of the metal artifacts dating to the Early Iron Age that archaeologists found on Somló Hill in Hungary.

Life’s little mysteries
How do archaeologists figure out the sex of a skeleton?
When archeologist chance a human skeleton in the cupboard , they are able-bodied to estimate whether that person was male or distaff with 95 % accuracy . But with most of the pick out piano tissue break down , how do researchers in reality go about sexing these ancient skeletons ?
No unmarried method acting is 100 % accurate , but archaeologist have several caper up their sleeves when it derive to distinguishing differences between sexual activity , from DNA analysis to measuring their finger cymbals .
‘Free-range’ atoms
In a first, physicists spot elusive ‘free-range’ atoms — confirming a century-old theory about quantum mechanics
For the first time ever , scientists have observed free - float atoms interact in space , confirming some of the most basic principles of quantum mechanic .
Single atoms are notoriously hard to contemplate due to their quantum behaviors , such as their ability to behave as a individual particle and a undulation at the same time . However , physicists at MIT have discovered that free - floating speck can be observed in " molecule swarm " with the help of laser .
" It ’s like seeing a swarm in the sky , but not the individual water molecules that make up the cloud,“Martin Zwierlein , a physicist at MIT and co - author of the new research , said in astatement .

The discovery enable scientists to capture images of these " free - compass " particle as they float about in space , which they go for will aid next investigation into other mysterious quantum mechanical phenomena .

‘If it was a man, we would say that’s a warrior’s grave’: Weapon-filled burials are shaking up what we know about women’s role in Viking society
diachronic depictions of woman often focalise on their use as mothers and homemakers — however , new research increasingly suggests that in Viking Scandinavia , somewomen were anything but meek and modest .
Numerous excavations have disclose distaff skeletons buried with lethal arm . " Women can be as substantial , as skilled , as tight as men,“Leszek Gardeła , an archaeologist at Ludwig Maximilian University of Munich and author of " Women and Weapons in the Viking domain : Amazons of the North " ( Casemate , 2021 ) , distinguish Live Science . " There is nothing in the biology there that would prevent them from being warriors . "
However , the poor preservation of Scandinavian graves and lack of historical texts make it very difficult to support the roles of these women in Viking society , leave the bailiwick of char warrior hotly deliberate among archaeologists .

Watch elusive New Zealand snail lay an egg through a ‘genital pore’ in its neck
In a reality first , a rare carnivorous snail has been filmedsqueezing a pearly-white egg out of a " genital pore " in its cervix .
Powelliphanta augustaare large snails found only on the Buller Plateau of New Zealand ’s West Coast . Their populations are severely imperil by local mining activeness , and very little is known about their life cycle due to their elusive , nocturnal behavior .
Researchers from the New Zealand Department of Conservation have been canvass these mysterious mollusks in immurement for nearly two decades , but only now have they observe one of these snails repose an egg .
" It ’s remarkable that in all the time we ’ve spend give care for the snails , this is the first time we ’ve seen one set an egg , " Lisa Flanagan , DOC ranger who captured the footage , said in astatement .
