Woolly mammoths won’t be trouncing through the Arctic tundra anytime soon.
Contrary to recent headlines, which herald the extinct beast’s coming resurrection, scientists are still a long way from figuring out how to revive the elephant ancestor.
Woolly mammoths roamed the planet for hundreds of thousands of years before they vanished about 4,000 years ago. Paleontologists say the culprit for the die-off was possibly overhunting, or changes in mammoth’s food supply after the last Ice Age.
A camp of scientists — known as “revivalists” — are dedicated to bringing mammoths back in the modern era for environmental and biological reasons. Some researchers have made important early progress, although nothing is close to leaving the lab.
The conundrum has stumped doctors for years. Why do neurodegenerative diseases such as Alzheimer’s affect only the elderly? Why do some people live to be over 100 with normal brain functioning while others develop dementia decades earlier?
Now, a new study by Harvard scientists points to a possible answer, one that could spark further research that — ultimately — could lead to new drugs and treatments for dementia.
Researchers have found that a protein active during fetal brain development, called REST, switches back on later in life to protect aging neurons from various stresses, including the toxic effects of abnormal proteins. But in those with Alzheimer’s and mild cognitive impairment, the protein — RE1-Silencing Transcription factor — is absent from key brain regions.
Our planet is warm. Outer space is cold. Can we take that heat difference and turn it into electricity?
Physicists at Harvard University may have found a way to do just that. They’ve proposed in a new study how to harvest the Earth’s thermal infrared radiation, and convert it into direct-current (DC) power.
“It’s not at all obvious, at first, how you would generate DC power by emitting infrared light in free space toward the cold,” study co-author Dr. Federico Capasso, a professor of applied physics and senior research fellow in electrical engineering at the university, said in a written statement. “To generate power by emitting, not by absorbing light, that’s weird. It makes sense physically once you think about it, but it’s highly counterintuitive. We’re talking about the use of physics at the nanoscale for a completely new application.”

On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat — beef, pork or lamb, for the purposes of the research — study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years). So what is it in red meat that might make it unhealthy?
A few years ago, we learned that too much TV might kill you sooner. Now, a new Harvard study is telling us excessive TV-watching could slash men’s sperm count, too.
The Harvard School of Public Health’s sperm study, published this week in the British Journal of Sports Medicine, determined that guys glued to the tube more than 20 hours per week had 44 percent less sperm than those who watched no TV.

Several Harvard students received a racist pamphlet on Friday advertising a club to which ‘no f***ing jews’ were allowed but “coloreds” were “ok” the Harvard Crimson reported.
The pamphlets, which were delivered in sealed envelopes under students’ dorm room doors, advertised “Harvard’s Newest Final Club” i.e. one of Harvard’s 14 single sex social clubs. The club, called the “Pigeon” (perhaps a play on the Final Club propensity to name their establishments after animals) was ostensibly promoting a party situated in a local frozen yogurt shop. The attire was dubbed “Semi-bro.”
How do you raise two sons who will make enough money by age 30 to ensure you have a very comfortable retirement? Tell them their youth is no barrier to achieving. Take them on vacations to developing countries where their imaginations can run wild with ideas for solving the planet’s greatest problems. And teach them to rebel in the right ways.
MY wife and I attended my 30-year college reunion a couple of weekends ago, but the partying was bittersweet. My freshman roommate, Scott Androes, was in a Seattle hospital bed, a victim in part of a broken health care system. Strip away the sound and fury of campaign ads and rival spinmeisters, and what’s at stake in this presidential election is, in part, lives like Scott’s.
Talk about flashbacks. New research suggests that LSD–a mind-altering drug known to cause recurrent hallucinations–may find new popularity not as a recreational drug but as a treatment for alcoholism.
In the world, human beings are facing various problems. People who are full of greed, anger, and ignorance are seen to be fighting with each other in words and deeds. As the fighting continues, various problems such as civil wars, wars of aggression, and wars of aggression are occurring. As world peace is being destroyed, humans are facing unbearable problems. Innocent children and women are not getting the rights they deserve and deserve. I can't think of one thing every time. What is it? The United Nations. If we look at the responsibilities and duties of the United Nations, I think it is not suitable for solving the problems that are happening in the world today. In fact, the United Nations and the World Security Council, such an organization must rule the world, must be able to give orders, and must have various ways to obey orders. There must be no organization that can influence more than that organization. There should be experts from each country. They can even dominate the superpowers like the US, China, and Britain. Only then will global peace be achieved quickly. Now, if a country with power develops more militarily, economically, or socially than its own country, then powerful countries will jealously seek out enemies and wage war. Or they will attack with fighter jets. In this, innocent people are losing their lives. No one understands the value of a life. You should think about how to achieve global peace by controlling these. If the US continues to be the permanent president of the UN, world peace will never be achieved. If you think carefully, no one sees that they are working for the common good, but for their own benefit, for the benefit of their own country. The permanent president of the UN and the Security Council has rejected this, As a young Rohingya, I have come to realize that only by electing the president and secretary from among the countries in the world through a secret ballot system and governing the world fairly can we achieve global peace. The United Nations and the Security Council are organizations in which any country must govern, give orders, and make them obey their orders. For example, only when a defendant is tried in court can we hold the leaders of the countries in check and control them, can we achieve global peace smoothly. Otherwise, it will not be easy for powerful countries to use various excuses to end this war every year, every year, for the benefit of themselves and their countries. No country's leaders pay any attention to the words of the United Nations and the Security Council. If we look at it in practice, look at the Rohingya issue. Myanmar is a small country. Even that country has been under siege for 8 years. What action can be taken? Why is the UN and the Security Council Powerless? Without such Power, how can the organization bring about global peace? Everyone should think about it. Whether there is a veto or a strong one, all countries in the world can only achieve global peace if they are subject to the UN and the Security Council. Seek peace in the quiet embrace of nature. Peace is an indispensable need of the human race. It is not as if one person can kill another person, and it is as if one country can attack another country, but instead of trying to build peace, we must try to destroy the peace now, and the world is getting hotter and is on the verge of collapse. I especially appeal to all the world experts to urgently try to bring about peace in all parts of the world. Mr, Noor Muhamed Arkhan Rohingya Youth Myanmar
