How did the world sound to our ancient human relatives two million years ago?

While we obviously don’t have any sound recordings or written records from anywhere near that long ago, we do have one clue: the fossilized bones from inside their ears. The internal anatomy of the ear influences its hearing abilities.

Emissions from the combustion of fossil fuels like coal, petroleum and natural gas tend to collect within Earth's atmosphere as "greenhouse gases" that are blamed for escalating global warming.

So researchers around the globe are on a quest for materials capable of capturing and storing greenhouse gases. This shared goal led researchers at Technische Universität Darmstadt in Germany and the Indian Institute of Technology Kanpur to team up to explore the feasibility of vertically aligned carbon nanotubes (VACNTs) to trap and store two greenhouse gases in particular: carbon dioxide (CO2) and sulfur dioxide (SO2).

The Indian ISRO space agency was going to announce the result of their first year of observations in Mars orbit - the Indian Times said - on Thursday.  But it didn't happen - seems it has been delayed! I look forward to hearing what they found - but seems that we have to wait some more.

We can't really make any deduction about what they will say, as their research is embargoed until then - they can't say anything about it. But we should hear whether or not they have detected methane from orbit so far.

As more people live sedentary lifestyles — and a growing body of evidence shows that sitting too long can be harmful — it appears that any type of movement can be beneficial for one’s health. A recent study published in the American Journal of Preventive Medicine suggests that even fidgeting may reduce some of the negative health effects for women who sit for long periods of time.

Western University researchers are working on a way to use artificial intelligence to predict a patient's response to two common chemotherapy medications used to treat breast cancer - paclitaxel and gemcitabine.

Peter Rogan, PhD, and a team of researchers, including Stephanie Dorman, PhD, and Katherina Baranova, BMSc, at Western's Schulich School of Medicine&Dentistry, are hoping to one day remove the guesswork from breast cancer treatment with this technique.

Based on personal genetic analysis of their tumours, patients with the same type of cancer can have different responses to the same medication. While some patients will respond well and go into remission, others will develop a resistance to the medication.

A Catholic, a Jesuit and a scientist walk into a bar. What do they have to talk about? And just how do those conversations go?

This scenario is no joking matter. Conflict as well as collaboration have characterized the historical relations between these three parties since the founding of the Society of Jesus, nearly 500 years ago. How do these three interact today in an era of “War on Science” that tends to politicize so many scientific issues?

Using endurance training or strength and resistance training not only prepares an athlete for different types of sports, they can also change the way the brain and muscles communicate with each other.

A University of Kansas study shows that the communication between the brain and quadriceps muscles of people who take part in endurance training, such as running long distances, is different than those who regularly took part in resistance training and those who were sedentary. The findings may offer clues to the type of physical activity humans are most naturally suited to.

The internet is buzzing with the announcement from NASA that they are going to announce the solution of a longstanding Mars mystery on Monday. at 11.30 am EST. That's 4.30 pm BST. Then, as many of the news stories have pointed out, the list of speakers includes Lujendra Ojha, a Nepal born researcher from Katmandu who discovered the "Warm Seasonal Flows" as an undergraduate back in 2011. It would be surprising to include him unless the solved mystery is something to do with these streaks. now often called Recursive Slope Lineae. So, what are they, and what are the main mysteries about them?

Though England, Scotland and Wales hold the top three spots as the most violent countries in the developed world, in America the ability to obtain a gun until after you have committed a crime leads even the ultra-violent UK to claim America needs to change.

Many in America contend guns do not cause crime any more than spoons cause obesity and instead point to the mental health - and drug-use to combat it - relationship. There haven't been any mass shootings that have occurred which did not involve mental health drugs.

Donald Spector, inventor and Chairman of the Board of New York College of Health Professions, believes that technology could be used to curb violence better than gun bans, which are the reason why the UK has so much crime.

By Michael Greshko, Inside Science – Mathematics that can describe coffeepots, forest fires and flu outbreaks may also underpin the brain’s response to anesthesia, a new study suggests.

The mathematical model of the brain, published in Physical Review Letters, marks the latest attempt to simulate the surprisingly complicated effects of general anesthetics across the brain.
