Oxygen Is Disappearing From the World's Oceans at an Alarmingly Rapid Pace. Updated | The ocean is running out of oxygen at a rapid speed—and the depletion could choke to death much of the marine life these waters support.
A sweeping review published Thursday in Science documented the causes, consequences and solutions to what is technically called “deoxygenation.” They discovered a four-to-tenfold increase in areas of the ocean with little to no oxygen, which researchers say is alarming because half of Earth’s oxygen originates from the ocean. Oxygen is crucial for marine life in the oceans.
Without oxygen, marine life will die off or relocate. “Animal life in the ocean needs oxygen to breathe,” Lisa Levin, study co-author and biological oceanographer at Scripps Institution of Oceanography at the University of California San Diego, told Newsweek. Overpopulation – The Human Explosion Explained. See Before-and-After Photos of the Changing Environment. Side-by-side comparisons reveal just how much glaciers, lakes, and snowpacks have been altered by nature and humans.
From the ice sheets of Greenland to the deserts of Arizona, many of the world’s landscapes have been dramatically transformed as their climate grows warmer and drier. At the same time, water use and other human activities have altered many landscapes. NASA has accumulated striking photos that show just how much our surroundings have changed. Putting Time In Perspective - UPDATED. Humans are good at a lot of things, but putting time in perspective is not one of them.
It’s not our fault—the spans of time in human history, and even more so in natural history, are so vast compared to the span of our life and recent history that it’s almost impossible to get a handle on it. If the Earth formed at midnight and the present moment is the next midnight, 24 hours later, modern humans have been around since 11:59:59pm—1 second. And if human history itself spans 24 hours from one midnight to the next, 14 minutes represents the time since Christ. Australia’s censorship of Unesco climate report is like a Shakespearean tragedy. That quote from Shakespeare’s Hamlet comes to mind: “The lady doth protest too much, methinks.”
The lady in question is the Australian government, which some time in early January saw a draft of a report from a United Nations organisation. 3-D scans turn fossils into print replicas. Nearly 20,000 fossils in Britain have been scanned and uploaded onto the Web, allowing the public to download them and print intricate replicas.
Thousands of prehistoric fossils have been rescued from dusty museum archives and made available online by the British Geological Survey as highly detailed 3-D models. Researchers and the public can now access almost 20,000 virtual fossils and print 3-D replicas. There are also plans in the works to digitally scan dinosaur fossils. Wildlife is absolutely thriving at Chernobyl disaster site. It's hard to find a bright side to the world's worst-ever nuclear disaster, but wildlife may beg to differ.
After the 1986 fire and explosion at the Chernobyl Nuclear Power Plant released radioactive particles into the atmosphere, everyone left, never to return. But now researchers studying animal populations have made a seriously counterintuitive discovery: The Chernobyl site looks less like a disaster zone and "more like a nature preserve," rife with elk, roe deer, red deer, wild boar, foxes, wolves, and others.

The sealed bottle garden still thriving after 40 years. David Latimer first planted his bottle garden in 1960 and last watered it in 1972 before tightly sealing it shut 'as an experiment'The hardy spiderworts plant inside has grown to fill the 10-gallon container by surviving entirely on recycled air, nutrients and waterGardeners' Question Time expert says it is 'a great example just how pioneering plants can be' By David Wilkes for the Daily Mail Published: 10:45 BST, 24 January 2013 | Updated: 16:33 BST, 6 March 2016 To look at this flourishing mass of plant life you’d think David Latimer was a green-fingered genius.
Truth be told, however, his bottle garden – now almost in its 53rd year – hasn’t taken up much of his time. In fact, on the last occasion he watered it Ted Heath was Prime Minister and Richard Nixon was in the White House.

One thing we've discovered over and over again is that nature is always weirder than what we give it credit for.
That's why, for instance, some of the most staggering naturally occurring landscapes on Earth don't look like they belong on Earth at all. They look like they were created in a lab, or beamed down to our world from a distant fold in the universe. Tell us you wouldn't think you'd been kidnapped by aliens if one day you woke up to see ... #11. World's first practical 'artificial leaf' unveiled. Washington, Mar 28 (ANI): Scientists from the Massachusetts Institute of Technology have finally developed the world's first practical artificial leaf that can split water into hydrogen and oxygen using sunlight at an economical cost, thereby achieving one of the milestones in the drive for sustainable energy.
They have described an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy. "A practical artificial leaf has been one of the Holy Grails of science for decades. We believe we have done it," said Daniel Nocera, who led the research team. The new discovery shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. Inside A Body Farm. When police come across the grisly remains of a human body, they need to identify details like time of death from biological clues. For instance, the amount of bloating and skin yellowing indicates how long a body has been decaying. What happens biologically after someone dies is studied in the field of forensic anthropology. The Forensic Anthropology Center at Texas State University is one of only five body farms in the world.
Undulating Cloud Cover. Reservoir holds billion-year-old water. Water filtering out of the floor of a deep Ontario mine has been trapped underground for more than a billion years. It bubbles with gasses carrying nutrients that could sustain microbial life. J Telling Scientists working 2.4 kilometres below Earth's surface in a Canadian mine have tapped a source of water that has remained isolated for at least a billion years. Student science experiment finds plants won't grow near Wi-Fi router.
Five ninth-grade young women from Denmark recently created a science experiment that is causing a stir in the scientific community. It started with an observation and a question. The girls noticed that if they slept with their mobile phones near their heads at night, they often had difficulty concentrating at school the next day. They wanted to test the effect of a cellphone's radiation on humans, but their school, Hjallerup School in Denmark, did not have the equipment to handle such an experiment. So the girls designed an experiment that would test the effect of cellphone radiation on a plant instead.
So, who are the smartest scientists? Finnish and Irish researchers have concluded physical scientists have higher IQs than social scientists and are less likely to believe in God. Source: Supplied SOCIAL science professors at elite institutions are more likely to be religious and politically extreme than their counterparts in the natural sciences, argues a new paper. Why? Natural scientists are just smarter. “There is sound evidence of a negative correlation between intelligence and religiosity and between intelligence and political extremism,” reads the paper in the Interdisciplinary Journal on Research and Religion which examines existing data on academic scientists’ IQs by field, and on religious beliefs and political extremism among science professors in the US and Britain.

Humans’ circadian clocks become skewed when they are exposed to electric lights but revert to a schedule more in tune with the sun when they go camping. FLICKR, ANJANETTEWLong-term exposure to electric lighting has fundamentally altered humans’ circadian rhythms, according to a study published in Current Biology last week (August 1). But a week camping away from electric lights swiftly reset eight study participants’ circadian clocks. How Diamond-Studded Magma Rises From Earth's Depths.
Pangaea with modern day borders. Look at What I'm Saying.
