What Killed Dinosaurs May Kill Cancer Cells Too

Nov 03 2017 - 12:11
The world’s second densest metal can be used to kill cancer cells by filling them with a deadly version of oxygen, without harming healthy tissue, according to a new paper.

The metal, iridium, was in the asteroid with the strongest link to the extinction of dinosaurs. When combined with organic material, the researchers showed it can be directly targeted towards cancerous cells, transferring energy to the cells to turn the oxygen (O2) inside them into singlet oxygen, which is poisonous and kills the cell - without harming any healthy tissue.

Computer Scientist Mark Jacobson Can't Sue His Way To Competence

Nov 03 2017 - 09:11
Starting Science 2.0 in 2006, I was as wide-eyed as anyone new to media could be.  My first month I was sure we were about to discover life on other planets, cancer was going to be cured, chocolate was healthy, resveratrol was the one polyphenol to rule them all. Oh, and academic scientists were going to rush to write for the public because I loved science. (1)

Tapanuli: A Third Orangutan Species Exists

Nov 02 2017 - 15:11
Move over, Bornean and the Sumatran orangutans. Scholars have identified a third orangutan species, the Tapanuli orangutan, that sits alongside the Pongo abelii, living on the island of Sumatra, and the Pongo pygmeaeus, endemic to Borneo, on the evolutionary tree.

Cosmic Rays Reveal New Hidden Room In The Great Pyramid

Nov 02 2017 - 11:11
The Great Pyramid, built under the command of the Pharaoh Cheops (who died around 2483 B.C.), retains a lot of mysteries. We don't know how it was built, which has led to any number of conspiracy stories about alien technology and other things.

Alien stuff has actually been able to help now, in the form of muons, by-products of cosmic rays which can be absorbed by stone. Using cosmic-ray muon radiography, a new study showed how researchers were able to non-invasively discover a previously unknown large room - its cross-section is similar to the Grand Gallery, so it is at least 90 feet long - above the Grand Gallery.

Palm Oil And Rainforests: Companies Are Abandoning Commitments, Says Group

Nov 01 2017 - 14:11
A San Francisco activist group claims major candy and snack manufacturers have deceived consumers by promising to clean up their palm oil supply chains, but these promises have been delayed, revised or watered down.

Palm Oil is a common vegetable oil, Nutella famously said their product won't be popular without it, and it has replaced partially hydrogenated oils in many uses due to higher yields than plants like rapeseed and sunflower plus stability at high temperature. But the popularity has come at a price.

These Minority Groups Have Alarmingly High Rates Of Obesity And Diabetes

Nov 01 2017 - 12:11

Though there are often conversations about the health of larger minority groups such as African-Americans and Hispanic-Americans, smaller groups are a real worry for an increasingly overburdened government health care system.

Darwin's Aliens: Extraterrestrials Could Be More Like Us Than We Think

Nov 01 2017 - 10:11

When we search the cosmos for evidence we are not the first advanced life form, we look for things that we could share in common. This anthropomorphism is common in culture, in everything from science studies to science-fiction. And it may not be wrong.

Assuming we have any extra-terrestrial neighbors, far less popular is the idea that we will be the advanced civilization new ones are terrified about being invaded by, they will likely have undergone natural selection just like we did. In the video game Spore, almost everyone evolved creatures that were purple and had huge eyes, despite trying to do things randomly, and that may happen on other planets also.

Wealthier Minorities Face More Discrimination And It's Being Blamed For Worse Health

Nov 01 2017 - 09:11

Rich people are more likely to shop at Whole Foods, buy supplements, vote for a particular political party and...racially discriminate against minorities? That last part is according to a new sociology paper which will force some inconvenient questions about race and money in America.

Though it is commonly believed that wealth leads to better health and less discrimination, wealthier African- and Latino-Americans report more racial discrimination than poor ones, according to survey results. Meanwhile, as whites became more wealthy they report improved health.

Genetically Engineered Wheat Can Boost Food Security

Oct 31 2017 - 15:10

Though genetically engineering food using science remains controversial in some circles, with concerns about genetically modified corn syrup in candy and claims that CRISPR can somehow be harmful whereas mutagenesis-derived foods can be labeled organic, progress marches on.

We're on our way to 9 million people and existing agriculture could easily handle it...if great agricultural land were evenly distributed. But is isn't evenly distributed, which is why the US and Europe can have robust markets for food created using an organic-certification process. Yield does not matter, just profit margins do, when land grows food easily.

Helmet Use In Baseball And Softball: Is Compliance Up?

Oct 30 2017 - 18:10

Traumatic brain injuries in baseball and softball are down, but they were not really all that high to begin with, and that may be why there is poor compliance overall with helmet use and return-to-play guidelines following concerns about a concussion.

The Future Of The LHC, And The Human Factor

Oct 30 2017 - 18:10
Today at CERN a workshop started on the physics of the High-Luminosity and High-Energy phases of Large Hadron Collider operations. This is a three-days event meant at preparing the ground for the decision on which, among several possible scenarios that have been pictured for the future of particle physics in Europe, will be the one on which the European Community will invest in the next few decades. The so-called "European Strategy for particle physics" will be decided in a couple of years, but getting the hard data on which to base that crucial decision is today's job.

Canadian Journal Claims E-Cigarettes Cause High School Student Smoking

Oct 30 2017 - 16:10

Surveys of students in two Canadian provinces have led scholars to warn that e-cigarettes, also called vaping, are causing cigarette uptake in high school students.

This will be a surprise to American and British public health officials, who know cigarette smoking has plummeted and even among those who get hooked, vaping is considered a viable harm reduction and smoking cessation alternative.

Bias Against Men When It Comes To Depression Treatment

Oct 30 2017 - 15:10

Though men account for the overwhelming majority of suicides and have increasingly sought help for depression, the clinical community has yet to figure out how to better help them. 

A new pilot study from Australia shows the extent of the problem. Men report that instead of receiving tailored treatment regimens more suited toward them, the clinical community seems to take a one-size-fits-all-genders unstructured talk therapy approach. Few gave their clients goals to work towards or outlined skills they could gain to deal with their depression, which was the opposite of the action-oriented, functional treatment the men were most often seeking.

Floods Of Fake “Astronomy News” Fill Apple & Google News - False Doomsdays Make Young Children Scared, Sick & Suicidal

Oct 28 2017 - 00:10

I've been writing Doomsday Debunking articles for some years now. The amount of fake news about the end of the world on the web is incredible. What makes it worse is that stories that say the world is about to end get widely shared, linked to, read over and over, and rise right to the top of Google and Apple news. Search google news for "Planet X" for instance and the top result is usually one or other article from the Daily Express who regularly publish fake news saying that an extra planet is about to hit Earth or fly past Earth in the next week or month.

Mapping The Wobbles Broke Another Dark Matter Hypothesis

Oct 27 2017 - 09:10

It may not seem to make sense but most of the universe - mass - can really only account for about 6 percent of what is going on. The rest of it can be under just about any umbrella at this point. Some call it the God of the Gaps, scientists call the unknown mass Dark Matter.

What is it? No one knows, when it comes to the very large and the very small, physics does not have all the answers, but something has made the universe at least 100 billion light years in size even though it's only 13 billion years old. As you know, a light year is the distance light will travel in that time. Since nothing can go faster than the speed of light, it's long been time to think about what Nothing is.

That's dark matter. And whatever is propelling it can be called Dark Energy.

A Simple Two-Mover

Oct 26 2017 - 16:10
My activity as a chessplayer has seen a steady decline in the past three years, due to overwhelming work obligations. To play in chess tournaments at a decent level, you not only need to be physically fit and well trained for the occasion, but also have your mind free from other thoughts. Alas, I have been failing miserably in the second and third of the above requirements. So I have essentially retired from competitive chess, and my only connection to the chess world is through the occasional 5-minute blitz game over the internet. -->

An End To Politicization Of Science At EPA?

Oct 26 2017 - 06:10
If scientists and journalists want the politicization of science to stop, they have to be part of the solution, even if a guy they didn't vote for is in power. But now that he is, all the talk about "depoliticizing science" has been exposed as the farce that we always knew it was.

Superheroes Against Science In Thor: Ragnarok

Oct 25 2017 - 18:10

Thor: Ragnarok is the latest Marvel movie (out in Australia today) that sees Australian Chris Hemsworth back as Thor, but he’s not on friendly home turf.

Instead he finds himself imprisoned on the opposite side of the universe from his beloved Asgard, and out of his depth in a gladiatorial contest with the Incredible Hulk (Mark Ruffalo).

But Hulk isn’t his only problem. Ragnarok (the end of his homeland of Asgard) is looming and Thor has new villains to deal with, including the warlike Hela, played by Australian Cate Blanchett.

A Different 1 Percent - Americans Who Carry Guns

Oct 25 2017 - 17:10

There is a different kind of 1 percent, and it isn't people who can afford to buy organic food. It's Americans who carry a handgun on a daily basis. 

It's not a surprise, given American history and horrific events like a psychopath in Las Vegas wounding or killing 500 people while police waited 70 minutes to attack him. A nearby hotel guest with a gun could have ended that more quickly.
