With the presidential election over, the focus in Washington, D.C., can finally turn back to policy and legislation.
Most of the conversations between President-elect Trump and Congress will probably involve immigration, health care, the economy and other similarly high-profile issues. But the nation's future path in space will also be under consideration — and it will probably generate some spirited debate.
One of the hottest topics will likely be the direction of NASA's human-spaceflight program, said Brian Weeden, a technical adviser for the nonprofit Secure World Foundation. [Gallery: 50 Years of Presidential Visions for Space Exploration]
In his first term, President Barack Obama canceled George W. Bush's moon-oriented Constellation program and instructed NASA to get astronauts to a near-Earth asteroid by 2025, then on to the vicinity of Mars by the mid-2030s.
To meet the first part of that directive, NASA devised the Asteroid Redirect Mission (ARM), which will pluck a boulder off a near-Earth asteroid using a robotic probe. This spacecraft will then haul the boulder to lunar orbit, where it will be visited by astronauts.
But ARM has its share of detractors, and some of them occupy positions of power on Capitol Hill. For example, earlier this year, the House of Representatives' Appropriations Committee proposed denying funding to the mission.
"The Committee believes that neither a robotic nor a crewed mission to an asteroid appreciably contribute[s] to the overarching mission to Mars," committee members wrote in a report. "Instead, NASA is encouraged to develop plans to return to the moon to test capabilities that will be needed for Mars, including habitation modules, lunar prospecting and landing and ascent vehicles."
This asteroid-versus-moon argument isn't likely to end anytime soon, especially since most of the international human-spaceflight community prefers the lunar option, Weeden said.
And that brings up another issue, he added: Just how much international cooperation will there be on NASA's envisioned journey to Mars and other big projects? Who will the partners be? Could China be involved, even though U.S. law currently prohibits NASA from working with China to any significant degree?
"That's a very big civil-space public policy question that the next administration will most definitely be tackling," Weeden said last week during a presentation with NASA's Future In-Space Operations working group. [5 Manned Mission to Mars Ideas

Also potentially on the docket, he said, will be the further mapping out of NASA's relationship with the private sector.
The George W. Bush and Obama administrations set NASA on a path that hands over many activities in low-Earth orbit (LEO) to private companies, theoretically freeing up the space agency to focus on more ambitious efforts, like getting people to Mars. For example, SpaceX and Orbital ATK currently fly robotic cargo missions to the International Space Station for NASA, and SpaceX and Boeing should start flying American astronauts to and from the orbiting lab in a year or two.
"That raises a bigger question about, Are there activities NASA has historically done that are perhaps better suited for the private sector to do?" Weeden said. "If so, how do you make that transition, and what does that mean for the future of NASA and NASA's workforce, and how NASA is organized?"
As the cancellation of Constellation and the push to scrap ARM show, NASA is often pulled this way and that by the president and Congress — not an ideal situation for an agency that's trying to plan out a crewed Mars mission and other activities 20 or 30 years in the future. So the next administration may investigate ways to ensure more policy stability for NASA, Weeden said.
The NASA administrator is currently nominated by, and serves at the pleasure of, the president. Some people have suggested that the NASA chief should instead be appointed by a panel, and/or serve a fixed term. Such changes would help shield the agency from partisan politics, the idea goes.
There are other important space-policy questions that must be dealt with at some point, Weeden said. For example, which federal agency (or agencies) should regulate the nascent asteroid-mining industry and other near-future space activities, such as private space stations and commercial moon outposts? Should the United States be in charge of cleaning up space junk, or should an international coalition lead this effort?
Then there's the national-security realm. Much of the United States' military might is based on the nation's dominance in space; for example, sharp-eyed spy satellites often give American warfighters a clearer view of the battlefield than their adversaries can get.
But other countries are increasingly contesting this dominance by developing their own advanced spacecraft and, in some cases, anti-satellite capabilities, experts have said.
"There's much more of a case that in future conflicts, there's probably going to be a space element of the conflict," Weeden said.
So the U.S. military is assessing how best to deal with this developing situation, he added.
"There's a discussion about, should the U.S. develop new offensive counterspace capabilities of its own, in part to deter adversaries, or perhaps to counter their own capabilities?" Weeden said. "And related to that: How might the U.S. deter potential adversaries such as Russia and China from kinetic attacks on space [assets] in a future conflict? And then, how best to leverage commercial industries and allies in that mix of resilience and assurance?"
President-elect Trump and Congress will therefore have a lot to talk about when it comes to space. And they may have fewer arguments than we're used to seeing, now that the presidency, House and Senate are all in Republican hands.

Facts About the Bear Dog By Alina Bradford, Live Science Contributor

Neither bear nor dog, these extinct animals evolved to be massive predators.

The bear dog, also called Amphicyon, shared features of bears (heavy-bodied, with feet planted flat on the ground) and dogs (relatively long legs and long snout), but they are neither bears (family Ursidae) nor dogs (family Canidae). 
They were not specifically in the bear's or dog's scientific families, but they are classified in the Caniformia, or "dog-like" suborder. Modern animals in the Caniformia suborder include wolves, foxes, dogs, bears, sea lions and weasels. This makes bear dogs something like cousins to their namesakes. Also, these bear dogs should not be confused with the modern dog breed, the Karelian bear dog.
There were two main types of bear dogs. Some, like Borocyon robustum, had long limbs that were ideal for running and looked much like modern wolves. Others, such as Amphicyon longiramus, were stocky and looked more like modern bears, according to the Florida Museum of Natural History
Much like dogs and bears of today, bear dogs had a range of sizes. They could weigh just few pounds or grow to over 1,000 lbs. (450 kilograms). It is thought that the early evolutions of the bear dog were very small, around Chihuahua size. As they continued to evolve, they seemed to have become progressively larger, according to The Field Museum
Evolving into bigger animals has several advantages and disadvantages. While becoming bigger would have enabled them to take down bigger prey and be higher on the food chain, they also would have required more food and reproduced more slowly. 
"Their massiveness suggest that they could prey upon many kinds of mammals and other animals. Fortunately, they were extinct before humans appeared on the scene," said Wilkins.
Bear dogs first appeared in Eurasia during the Eocene and Oligocene epochs (55.8 million to 23 million years ago), time periods full of warm weather and thick vegetation. The temperature around the world stayed around 86 degrees Fahrenheit (30 Celsius) during the Eocene period, according to the University of California Museum of Paleontology.
Though the temperatures cooled in the Oligocene, it was still quite warm and vegetation flourished in most locations around the world, including North America and Africa. Bear dogs became extinct 5 million to 10 million years ago.
The bear dog's teeth were shaped to allow for an omnivorous diet, much like modern bears and modern dogs. Prey for smaller bear dogs may have included rodents while bigger beardogs would have eaten larger animals such as wild hogs. Bear dogs may have also enjoyed leaves and berries.

Why I weep over Nigeria

Why I weep over Nigeria 
It was Ngugi Wa Thiong’o that cautioned us in his famous novel ‘ Weep Not child’ that we should refrain from weeping despite the level of injustice and all forms of oppressions. But I guess Alan Paton understood the vulnerability in human and gave a little permission for human to cry when he wrote ‘ Cry For the Beloved Country’. In the setting of these great two books were high level of injustice, inequality amongst others.
Let me begin by saying I am not a wailing wailer. This will be my first article with such a headline. I have refrained from such headline because I do not like to weep emotions of others. Just telling what is: enumerating the problems without offering solution. The essence of this piece is an indication of my value for the Nigeria project.
As we know, what you value you stay committed to. I constantly think about this project called Nigeria. I see we have lost the sense of worth for human life in all ramifications. Two days ago, the uncle of a colleague died in Lagos University Teaching Hospital and his conclusion was that his uncle died a cheap death. It means under different condition, environment his uncle will still be alive and kicking.
I can relate with him and that is the fear I have about Nigeria hospitals till date. I have lost my facial nerves to a seemingly knowledgeable doctor negligience and he neither told me why he needed to do that, nor asked for my permission before he went ahead. He did not even see reason to inform me of what he had done until I sought treated elsewhere where patients’ rights is a big issue. They carried patients along in every issues that concern their health. Patient health and well being is a joint process, efforts between doctors and patients. But here, doctors are Lords of the rings.
We keep saying we have the best of the doctors. I really do not doubt this, but there is always a need to proof that. Lives are lost everyday in droves in our hospitals due to negligence, lack of equipment and relevant manpower. The deaths in hospitals are the ones we see or know of.
Many died in varied needless road accidents and in their homes for seemingly insignificant diseases. Over the world, it is now an aberration for a woman to die while giving birth but what do we see here? Hundreds of women died and life continues. If in doubt, check your popular ‘elewe omo clinic’. I have seen where some women who were pregnant went to normal hospital for just minor ailment and nurses had given them injections that had led to their death just because necessary checks were not done.
I read in the paper in the course of the week that an ex -Custom boss returned One Billion Naira cash to the Federal Government. For hours, my body developed goose pimples. My thinking was if one person can return One Billion Naira cash, does that mean he still has more that is kept somewhere? Are there indication that you may have some more in various bank accounts? In a country where people live under one dollar a day? Interestingly we have lost the power to appreciate value in money. It was Reno Omokri that said “Abati is imprisoned for fifty Million while Rotimi Ameachi spent about N223Million’ on a state function”. What a word. To Reno, fifty Million is just.
I have nothing personal against Dr Abati. My reference to him was just what Reno said. In the environment where Mr. Reno Omokri lives, has anyone ‘eaten’ fifty Million Dollars and he is allowed to go Scot free? Is Reno also making Fifty Million Dollars in a year as personal income in the US where he lives?
Let us not talk about Naira value here but match the amount with the currency of the Country he lives? No one will blame him and others who see fifty Million as just. But I must let him know we have about five public secondary schools in my home town and with that amount, the schools will become international schools overnight if I have that kind of money to repatriate to my home town.
Our schools have become dilapidated and their ailing overstretched facilities are put into ‘abusive’ use by packing hundreds of pupils in make shift classes. Many factories are packing up and no one is talking or taking notice as it were.
While I do not support stealing in any form, but peradventure those who had stolen Nigerian money thought of reinvesting these into the economy thereby reducing the level of unemployment, may be some will be praying for them today. After all we have seen cases where huge crowds had been rented to protest ‘illegal humiliation of their “daughters and sons” in courts where government had taken them to to return unlawful wealth found in their possession. Our sense of thinking right had been dealt with badly by poverty so anything goes with a stipend of five thousand Naira.
Has someone also noticed young people being used as product canvassers in Lagos? While it is good to engage in profitable and legal business for sustenance, my heart bleeds each day I see this happens? Those young girls and boys stay in the sun and rain throughout the day because of five thousand and in most cases I understand they are even owed after all the gymnastic they are subjected to.
Theirs is even better, have we noticed the level of sexual harassment under age girls selling stuff on Lagos roads suffered in the hands of bus conductors? These are voiceless people who may not have anyone to fight for them. Yes, in my part, I do have a non profit crusading for child education and girl child rights but how many of these girls can we rescue?
Anyway, enough of the problems, what do I think we can do to correct the anomalies above? I think behind the camouflage of Public servants who steal so much while in office is fear of tomorrow. We stand to be corrected though. They have seen few of their colleagues who were upright and had served faithfully while in office turned to become beggars for what they hope to be their life sustenance (pension). Many of them had denied their payments long after retirement. So can we appeal to Government to recognize those who serve faithfully by building them a house? Is it also possible to make house ownership become common place through varied options available in advanced world?
For instance, can we build affordable houses with rent-to-own? Can anyone with little but stable income buy a house as well as own a car with a long term payment plan? Oh, someone says they are already here, but how affordable are they for people living under one Dollar a day? These things not luxury in most advanced countries? They are necessities? Is it also possible to make food so cheap everyone can access them? Our people say ‘if hunger is removed from poverty, what remains is bearable’.
Can we put in place affordable health care with capable, competent and customer-centred staff who will not abuse anyone or patient as it were? Can we place value on every human life whether s/he has money or not? Can we teach values and right orientation of success in our schools again? That no one should be intimidated by others because of their success or wealth?
Can our justice system be reprogrammed to punish any one in error irrespective of status or class? That we no longer delay justice when it is due? For if I know I can manipulate the system and delay judgement till eternity, why should I not do things and get away with it?
Can we encourage our youth to say no to injustice and our traditional leaders to stop awarding traditional titles to those who they knew their sources of wealth are questionable?
Can everyone of us learn not to take nothing less than what is ideal in service to us? In South Africa, there has been protest aimed at forcing President Zuma to resign because of high level of alleged corruption.
In South Korea, there had been protest to force the President to resign for alleged abuse of office. Will Nigerians ever gotten to this level? Our government knows how to create the fear by sending hungry Soldiers and Policemen into the street to deal with the crowd ‘appropriately’. When the pupils are ready, the teacher will surface.

Entelodonts: Facts About Giant Killer 'Pigs' By Alina Bradford, Live Science Contributor

Entelodonts: Facts About Giant Killer 'Pigs'
Dinohyus hollandi was a species of entelodont, of hell pig.

Entelodont is a name given to any member of the extinct scientific family Entelodontidae. These large, primitive animals are also known as hell pigs. However, they are not related to modern pigs; rather, they are closer on the evolutionary tree to hippos and whales.  
Entelodonts were among the earliest of the pig-like lineages, known from the early to middle Eocene (c. 50 million years ago), according to Kenneth T. Wilkins, associate dean for sciences at Baylor University, Waco, Texas. 
Entelodontidae first appeared in Mongolia, then spread across Asia, Europe and North America. They eventually became extinct between 19 million and 16 million years ago, according to Encyclopedia Britannica. 
In North America, the hell pigs seemed to prefer floodplains as their home of choice. Woodlands where also preferred by hell pigs of many types.
Even small hell pigs were quite large. The smallest of the hell pigs grew to around 330 pounds (50 kilograms), while the largest grew to around about 2,000 lbs (900 kg).
One of the better-known entelodonts was Archaeotherium, which were common in western North America. These were large animals, several times the size of modern pigs, with the skull reaching near more than 3 feet (1 meter) long. "The dentition suggests they were effective bone-crushers. These surely were fierce, imposing animals . . . hence, the common name 'hell pig,'" said Wilkins.
Many hell pigs had heads that were massive when compared to their bodies. Another example is the Dinohyus. Its head was 35 to 45 percent of its total length, according to Encyclopedia Britannica
Large scars, up to 0.8 inches (2 centimeters) deep, found on the remains of hell pigs suggests that they fought with their own kind. Research also suggest that one hell pig would even put another's head in its mouth during a fight, according to BBC Nature. The hell pigs had boney areas on their faces that protected their nose and eyes during these types of attacks. 
Though it would be easy to assume that such a fierce creature with large tusks and imposing body size were carnivorous predators, the hell pig's teeth say differently. More than likely, they were omnivores, eating plant life as well as meat.
The front teeth where large and pointed, perfect for ripping flesh from bone. The back teeth were flat, which is perfect for crushing plant material. Fruits, leaves and seeds, as well as other animals and eggs were probably all part of the hell pig's diet.
It may not have even been a killer. Some believe that hell pigs may have been scavengers, letting other animals make the kills. Once the prey was dead, the hell pig may have intimidated the predator and taken its prey, according to National Geographic.
