Uranus Hit by a Rock Twice the Size of Earth

The Only planet to spin on it’s side, Uranus, was smashed into by a rock double the size of Earth, 3 billion years ago, according to Duke University space researcher Jacob Kegerris. Uranus is unique in that the planet tilts about 90 degrees on its side. Even their poles are lopsided at an angle. Researches are exploring the possibility that perhaps the “rock” was incorporated into the planet or it may still be roaming the solar system.

Getting Rid of Bad Genes

SPR-Cas9 gene editing has become a genome editing tool that has enhanced scientific research, but has also caused much controversy and concern over its potential applications. With the potential of becoming a tool to fix incurable genetic diseases, the safety and efficiency of CRISPR needs to be extensively investigated to ensure that only the desired DNA modifications are made. Recent studies published in Nature have discovered how editing efficiency in cells can be influenced by the DNA damageresponse, and are raising concerns after finding that


CRISPR cuts can result in larger unwanted DNA rearrangements than previously thought. HONG KONG, CHINA On the eve of an international summit here on genome editing, a Chinese researcher has shocked many by claiming to have altered the genomes of twin baby girls born this month in a way that will pass the modification on to future generations. The alteration is intended to make the children’s cells resistant to infection by HIV, says the scientist, He Jiankui of the Southern University of Science and Technology in Shenzhen, China. He was dismissed from his job and arrested by the Chinese government for doing research without permission.


Saturn’s Rings Disappearing


Saturn’s Rings are made up of various forms of ice, formed less than 100 Millions years ago. The ice chunks are being pulled by gravity into the center. Meteoroid strikes and ultraviolet light from the sun is the culprit. This process will eliminate the rings in 300 Million years according to James O’Donoghue, NASA’Goddard Space Flight Center. Humans Have 1 -3 %


Nanderthal Genes: Good Or Bad?


Scientists are still a long way from understanding what inheriting a Neanderthal gene means to people. Some Neanderthal genes may be helpful — improving our defenses against infections, for example — but other bits more prone to other diseases. A team of scientists revealed that two pieces of Neanderthal DNA may have another effect: They may change the shape of our brains. The study, published in the journal Current Biology, wasn’t designed to
determine how Neanderthal genes influence thought — if they do so at all. Instead, the value of the research lies in its unprecedented glimpse into the genetic changes influencing the evolution of the human brain. Other Neanderthal researchers, like Andrew Sorensen, a Dutch doctoral student, investigated whether Neanderthals were able to produce fire. Minera traces left on ancient tools were very similar to the ones he recently created fire by rubbing
pyrite against his own biface. Neanderthals genes are all around us. Who are they? Look out for those with sloping foreheads. They might be your inlaws.


New Fossil Controversy RE: Australopithecus sediba


With its fossils dated to 1.98 million years ago, Au. sediba is too young to be directly ancestral to all members of the genus Homo. But Lee Berger and his colleagues proposed in 2010, and again in 2013 in six papers in Science, that given the many humanlike traits in Au. sediba’s face, teeth, and body, the Malapa fossils were a better candidate than Lucy or other East African fossils to be ancestral to Homo erectus, a direct human ancestor that appeared 1.8 million years ago. Paleoanthropologist Bill Kimbel of Arizona State University in Tempe analyzed the most complete skull of Au. sediba and systematically shot down the features claimed to link it to early Homo. Kimbel noted that the skull was that of a juvenile—a “7th grader”— whose face and skull were still developing. In his analysis, with paleoanthropologist Yoel Rak of Tel Aviv University in Israel, he concluded that thechild already showed traits that linked it most closely to the South African australopithecine Au. africanus, a species that lived in South Africa 3 million to 2.3 million years ago. And had it survived to adulthood, its humanlike facial traits would have changed to become even more like those of Au. africanus. Is Lucy, (3.75 MYO) out?

Why Drink Milk?

Milk is a top food source for calcium, potassium and vitamin dairy products and are also a good source of protein which helps rebuild and repair muscle according to Dr. Gregory Miller,PhD, FA, Chief Science Officer at National Dairy Council. Scientists at Trinity College in Dublin found that women who consumed yogurt daily decreased their osteoporosis risk by 39 %, i.e. The more you eat the less likely you are to develop osteoporoses. Don’t like milk, eat cheese or drink low fat milk. Alzheimers May First Start in the Body Outside the Brain Amyloid beta proteins, produced in blood platelets, blood vessels and muscles, are being studied by Prof. Weihong Song, University of British Columbia, to study whether the affliction first starts outside the brain.

 
     
 


 
     
   
   
   

Happenings
At A Glance

1. Macedonia Is Greece
Ever since the Republic of Macedonia declared its independence in 1991, Greece has been fighting
the country over its name. Today the 27- year impasse ended as two nations finally came
to a resolution: The former Yugoslav republic
is getting a new name, the Republic of North
Macedonia.
2. Japanese Babe Ruth
Los Angeles’ Shohei Ohtani, the New Babe
Ruth, became the first baseball player to hit 20
home runs and pitch 50 innings since the Babe.
3. Skating On The Moon?
34 million miles away, the 51 mile Korolev ice
crater on the moon would be a great place to go
ice skating according
to the European
Space Agency,
which launched
the Mars Express
in 2003 and took
6 months to get
there.
4. Nuclear Collider in Switzerland
The Huge 17 mile Hedron Collider in Meyrin,
Switzerland will be closed for 2 years for an
upgrade. The European Center for Nuclear
Research installed the Collider in order to determine
how new particles and forces of nature
develop. The Collider measures the energy of
particles produced when 2 particles travel close
to the speed of light before they collide.
In the United States, the Superconducting
Super Collider (SSC) (also nicknamed the Desertron)
was a particle accelerator complex under
construction in the vicinity of Waxahachie,
Texas The project was canceled in 1993 due to
budget problems.
5. Minoan Cemetery Excavation in Petras
An international team of archaeologists headed
by the director emerita of the ministry of culture
Metaxia Tsipopoulou which is digging at Petras,
on the eastern edges of the city of Siteia on Crete, has discovered a large number of gold and silver
jewelery, numerous bronze implements
(many used for grooming) and other objects.
6. Turks Fleeing Erdogan Fuel New Influx
of Refugees to Greece
In the dead of night, Yunuz Cagar and his wife
Cansu gave their baby some herbal tea to help
her sleep, donned backpacks and followed
smugglers on a muddy path along the Evros
river, evading fences and border guards until
they reached Greece.
