Out of the Earth, Out of the Blue

A new early human fossil has been reported, recovered from the seabed near Taiwan. We are calling it Penghu 1. Simply put, it is the lower right jaw of a hominid (hominine) that most resembles either a form of Homo erectus or Archaic Homo sapiens (kin to, but not, Neanderthal). Teeth are fairly useful for…

An unexpected find and very exciting moment for researchers exploring what lies beneath 740 meters of ice in Antarctica…fish! An amazing find given the perpetual darkness and cold. In an expedition sponsored by the National Science Foundation, scientists and ice drillers bored a hole through the Ross Ice Shelf near the coast of Antarctica, 850…

Surprise!

Uncertain Principles January 28, 2015

Over at Curious Wavefunction, Ashutosh Jogalekar offers a list of great surprising results in physics. This is fairly comprehensive, but leaves out one of my favorites, which is the discovery of the muon. Muons are particles like electrons, but a couple hundred times heavier. When they were first detected in cosmic ray traces in 1936,…

Greg Laden reports on a hominid fossil "recovered from the seabed near Taiwan" which reveals new levels of dental diversity among proto-humans and may qualify as a new species. Greg says the specimen known as Penghu "is yet another indicator that multiple different hominids lived on the Earth at the same time after the rise of Homo erectus." But why was it located underwater? In another example of what lies beneath, Dr. Dolittle marvels at "an unexpected find and very exciting moment for researchers;" the discovery of small fish and invertebrates thriving below 740 meters of ice near the coast of Antarctica. Exactly how these animals survive in the stark ecosystem has yet to be determined. Meanwhile, on Uncertain Principles, Chad Orzel reflects on the history of surprising physics discoveries. He provides as an example the discovery of the muon in 1936, a subatomic particle that no one was even looking for. Chad writes, "The eminently quotable I.I. Rabi famously responded to the news by asking 'Who ordered that?'" No one, but we'll take it.

I am pretty excited about Puppy Bowl XI tomorrow afternoon on Animal Planet! So cute! (3pm) Team Ruff vs Team Fluff http://www.animalplanet.com/tv-shows/puppy-bowl/about-this-show/about-puppy-bowl/

Unfortunately, this event is not on my calendar: the Cephalopod International Advisory Council (CIAC) is meeting 8-14 November in Hakodate, Japan, to discuss recent advances in cephalopod science (pdf). It looks delightful. I’ve always wanted to visit Japan. But alas, all I can do is tell you you should go.

How would you feel if NOAA sent a camera to snoop around your most intimate moments, huh?

The Great DeflateGate Controversy This year’s Super Bowl will be, as of this writing, tomorrow, late afternoon, between the New England Patriots and the Seattle Seahawks. Both teams have a 14-4 record for the season, so it should be a good game. Also, the game will be held in a stadium located in an arid…

“Time is the longest distance between two places.” -Tennessee Williams I’m always stoked to give you weekly recaps at Starts With A Bang, just in case there’s anything you missed. We saw some fantastic posts this week, including two amazing contributions from Brian Koberlein and Amanda Yoho! Here’s what we saw: The timeline of the Universe (for Ask…

“Go then, there are other worlds than these.” -Stephen King, The Dark Tower Ever since quantum mechanics first came along, we’ve recognized how tenuous our perception of reality is, and how — in many ways — what we perceive is just a very small subset of what’s going on at the quantum level in our…

The Willie Soon Controversy There’s been a lot of talk about the Willie Soon Controversy. Bottom line: Soon was an author on a paper that failed to disclose his extensive funding by the petroleum industry and its friends (over a million dollars to date, I believe) as required. I don’t have time to craft a…

The Austrian Alpine Club (Sektion Brittania) runs an annual photo competition. I’ve finally got round to entering some of my summer pix; see here. Here’s my favourite that I didn’t enter; this was part of Stubai: Wilder Freiger by the Lubeckerweg.

It’s not unusual for studies on community walkability to face the perplexing question of self-selection. In other words, people who already like to walk end up moving to walkable communities and so those communities naturally have higher physical activity rates. In even simpler terms, it’s about the person, not the environment. However, a new study finds that walkable community design does influence healthy behavior — even among people with no preference for walking in the first place.

Evidence has been accumulating about the toll of prolonged sitting, and a new systematic review and meta-analysis published in the Archives of Internal Medicine shows just how harmful sedentary habits can be.

Education

Something interesting happened in 2014. The total number of databases that Nucleic Acids Research (NAR) tracks dropped by three databases! What happened?  Did people quit making databases?  No.  This year, the “dead” databases (links no longer valid) outnumber the new ones. To celebrate Digital World Biology’s release of Molecule World I’ll discuss some of the new structure databases…

Science Teaching researcher Prof. Nir Orion  recently returned from Peru, where his award-winning Blue Planet teaching unit was adopted by the Peruvian Ministry of Education Q: You have been working for many years to get schoolchildren out of the classroom setting. Why? A: Schools in general and science teaching in particular are supposed to teach…

The closing of the Vermont Yankee Nuclear Power plant didn’t make many headlines, but for me it brought back a flood of memories and an important lesson.

I’m not in the mood for heavy blogging just now, so how about we discuss something light and frivolous. Like the meaning of life. Back in July, I wrote this: Answers about our origins have no implications at all for questions of meaning and value. Arising through blind, uncaring forces in no way implies that…

In the week before his 2015 State of the Union address, President Obama took modest but important steps toward expanding US workers’ access to paid sick and family leave.

Yesterday, I wrote about false balance in reporting on vaccines in the wake of the Disneyland measles outbreak. For those who’ve never encountered this blog, what I mean by false balance is when journalists, in a misguided belief that there are “two sides” (i.e., an actual scientific controversy) about the safety of childhood vaccines and…

Imagine, if you will, a time machine capsule going all the way back to the earliest days of this blog, back in 2005 and 2006. Now consider the antivaccine movement, which somehow I became very interested in very early, an interest that continues to this day. Do you remember one theme that I kept hitting…

If there’s one aspect of 2014 that I enjoyed, it’s that it was a very bad year for our old friend, America’s quack, a.k.a. Dr. Mehmet Oz. It seemed that, finally, some of the chickens were coming home to roost and Dr. Oz was starting to suffer a bit for his promotion of quackery and…

Dr. Thane Wibbels (University of Alabama at Birmingham) is interested in studying how temperature affects the sex of red-eared slider turtle embryos. For humans, the answer is simple: sex chromosomes. You know, the combination of XX means girl and XY means boy. Turtles are not that simple. Temperature is a factor in determining whether the…

I came across an interesting study published last month in American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on obstructive sleep apnea (OSA), which is a disorder in which the upper airway is repeatedly obstructed during sleep resulting in bouts of intermittent hypoxia (low oxygen concentrations). I had no idea that OSA is…

Just a note to celebrate the life and times of Hedy Lamarr, who died on this day, 2000, at the age of 85. Lamarr had a very interesting career that involved major acting accomplishments, milestone acting events, and direct involvement in the invention of the technology that now forms the basis of WiFi, BlueTooth and…

I’ve decided to do a new round of profiles in the Project for Non-Academic Science (acronym deliberately chosen to coincide with a journal), as a way of getting a little more information out there to students studying in STEM fields who will likely end up with jobs off the “standard” academic science track. The fourteenth…

I’ve recently written about the Serengeti Strategy, a coin termed by climate scientist Michael Mann to describe the anti-science strategy of personal attacks against individual scientists in an attempt to discredit valid scientific research one might find inconvenient. Science Careers (from Science Magazine) has a new item called “Science under the microscope” looking at bad…

On May 20th, 2013 I published my most popular post ever. It was The Canadian War on Science: A long, unexaggerated, devastating chronological indictment. In it, I chronicled at some considerable length the various anti-science measures by the current Canadian Conservative government. The chronological aspect was particularly interesting as you could see the ramping up…

This week’s snapshot of just one work-related fatality in the U.S. This one occurred on January 23, 2015 in Middletown, CT.

Rarely do poverty and optimal health go together. In fact, income is consistently tapped as a major factor underpinning a person’s opportunity to live a long and healthy life. Unfortunately, children don’t fare much better, with low-income children facing increased risks of poor health and development. So, just how many American children face this challenge today? Four out of every 10.
