Science X Newsletter Week 32

Dear Reader ,

Here is your customized Science X Newsletter for week 32:

Probiotic use is a link between brain fogginess, severe bloating

Probiotic use can result in a significant accumulation of bacteria in the small intestine that can result in disorienting brain fogginess as well as rapid, significant belly bloating, investigators report.

Chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.

Earth risks tipping into 'hothouse' state: study

The planet urgently needs to transition to a green economy because fossil fuel pollution risks pushing the Earth into a lasting and dangerous "hothouse" state, researchers warned on Monday.

Laziness led to extinction of Homo erectus

New archaeological research from The Australian National University (ANU) has found that Homo erectus, an extinct species of primitive humans, went extinct in part because they were 'lazy'.

Scientists find that common dietary elements cure lethal infections, eliminating the need for antibiotics

Antibiotic use is driving an epidemic of antibiotic resistance, as more susceptible bacteria are killed but more resilient strains live on and multiply with abandon. But if antibiotics aren't the end-all solution for infectious disease, what is?

US jury orders Monsanto to pay $290mn to cancer patient over weed killer

A California jury ordered chemical giant Monsanto to pay nearly $290 million Friday for failing to warn a dying groundskeeper that its weed killer Roundup might cause cancer.

Researchers won't take dead orca calf away from mother as she carries it into a 17th day

As Tahlequah carries her deceased calf for a 17th straight day, and concerns mount about her health, taking the calf away is not an option because of the tight bond between Tahlequah and the rest of the pod to her baby—dead or alive, experts say.

Discovery of copper band shows Native Americans engaged in trade more extensively than thought

A research team including Matthew Sanger, assistant professor of anthropology at Binghamton University, State University at New York, has found a copper band that indicates ancient Native Americans engaged in extensive trade networks spanning far greater distances than what has been previously thought.

Mini antimatter accelerator could rival the likes of the Large Hadron Collider

Researchers have found a way to accelerate antimatter in a 1000x smaller space than current accelerators, boosting the science of exotic particles.

Spider venom strikes a blow against childhood epilepsy

A devastating form of childhood epilepsy that is resistant to traditional drugs may have met its match in spider venom.

The universe's rate of expansion is in dispute – and we may need new physics to solve it

Next time you eat a blueberry (or chocolate chip) muffin consider what happened to the blueberries in the batter as it was baked. The blueberries started off all squished together, but as the muffin expanded they started to move away from each other. If you could sit on one blueberry you would see all the others moving away from you, but the same would be true for any blueberry you chose. In this sense galaxies are a lot like blueberries.

Study shows global forest loss over past 35 years has been more than offset by new forest growth

A team of researchers from the University of Maryland, the State University of New York and NASA's Goddard Space Flight Center has found that new global tree growth over the past 35 years has more than offset global tree cover losses. In their paper published in the journal Nature, the group describes using satellite data to track forest growth and loss over the past 35 years and what they found by doing so.

Engineers teach a drone to herd birds away from airports autonomously

Engineers at Caltech have developed a new control algorithm that enables a single drone to herd an entire flock of birds away from the airspace of an airport. The algorithm is presented in a study in IEEE Transactions on Robotics.

Key aspects of human cell aging reversed by new compounds

Key aspects of the ageing of human cells can be reversed by new compounds developed at the University of Exeter, research shows.

Household phenomenon observed by Leonardo da Vinci finally explained

An everyday occurrence spotted when we turn on the tap to brush our teeth has baffled engineers for centuries—why does the water splay when it hits the sink before it heads down the plughole?

More than half of drivers don't look for cyclists and pedestrians before turning right, study finds

U of T Engineering researchers studied the eye movements of drivers at busy Toronto intersections and found that more than half failed to make necessary scans for pedestrians or cyclists at right turns.

Tiny tunnels inside garnets appear to be the result of boring microorganisms

Complex systems of microscopic tunnels found inside garnet crystals from Thailand are most likely the result of microorganisms making their homes inside these minerals, according to a study published August 8, 2018 in the open-access journal PLOS ONE by Magnus Ivarsson of the University of Southern Denmark and colleagues.

North American diets require more land than we have, study says

If the global population adopted recommended North American dietary guidelines, there wouldn't be enough land to provide the food required, according to a new study co-authored by University of Guelph researchers.

Top 43 reasons why men remain single—according to Reddit

In the past, forced or arranged marriages meant that socially inept, unattractive men did not have to acquire social skills in order to find a long-term love interest. Today, men must be able to turn on the charm if they want to find a partner. Those men who have difficulty flirting, or are unable to impress the opposite sex may remain single because their social skills have not evolved to meet today's societal demands. So says Menelaos Apostolou of the University of Nicosia in Cyprus in a study in Springer's journal Evolutionary Psychological Science. Apostolou analyzed more than 6,700 comments left by men on the popular social news and media aggregation internet site Reddit.

Study finds flaw in emergent gravity

In recent years, some physicists have been investigating the possibility that gravity is not actually a fundamental force, but rather an emergent phenomenon that arises from the collective motion of small bits of information encoded on spacetime surfaces called holographic screens. The theory, called emergent gravity, hinges on the existence of a close connection between gravity and thermodynamics.
