Pregnancy Alters Woman’s Brains ‘For At Least Two Years’

EzInKy writes: The BBC and others are reporting the results of a study that women’s brains do in fact change during pregnancy. BBC reports: “Pregnancy reduces grey matter in specific parts of a woman’s brain, helping her bond with her baby and prepare for the demands of motherhood. Scans of 25 first-time mums showed these structural brain changes lasted for at least two years after giving birth. European researchers said the scale of brain changes during pregnancy were akin to those seen during adolescence. But they found no evidence of women’s memory deteriorating. This study, from researchers at the Universitat Autonoma de Barcelona and Leiden University and published in Nature Neuroscience, looked at the brain scans of women before they became pregnant, soon after they gave birth, and two years later, to see how the brain changed. And they compared these women’s brains with those of 19 first-time fathers, 17 men without children and 20 women who had never given birth. The researchers found ‘substantial’ reductions in the volume of grey matter in the brains of first-time mothers. The grey matter changes occurred in areas of the brain involved in social interactions used for attributing thoughts and feelings to other people — known as ‘theory-of-mind’ tasks. The researchers thought this would give new mothers an advantage in various ways – help them recognize the needs of their child, be more aware of potential social threats and become more attached to their baby.” Thanks Mom! As for first-time fathers, the researchers found no changes in their grey matter. Read more of this story at Slashdot.

China Chokes On Smog So Bad That Planes Can’t Land

Major cities across northern China choked Monday under a blanket of smog so thick that industries were ordered shut down and air and ground traffic was disrupted. From a report: At least 23 cities issued red alerts for a swath of pollution that has hovered over much of the nation since Friday, China’s Xinhua news agency reported. Alerts are expected to remain in effect through Wednesday. Hospitals set emergency procedures in motion to deal with an influx of breathing-related illnesses. Large hospitals in the port city of Tianjin, less than 100 miles southeast of Beijing, saw a surge in asthma and other respiratory issues, China’s People’s Daily reported. The pollution forced the city to close the highways and caused delays and cancellations for dozens of flights, Xinhua said. Read more of this story at Slashdot.

First Dinosaur Tail Found Preserved in Amber

The tail of a beautiful, feathered dinosaur has been found perfectly preserved in amber from Myanmar. It is a huge breakthrough that could help open a new window on the biology of a group that dominated Earth for more than 160 million years. From a report on the National Geographic: The semitranslucent mid-Cretaceous amber sample, roughly the size and shape of a dried apricot, captures one of the earliest moments of differentiation between the feathers of birds of flight and the feathers of dinosaurs. Inside the lump of resin is a 1.4-inch appendage covered in delicate feathers, described as chestnut brown with a pale or white underside. CT scans and microscopic analysis of the sample revealed eight vertebrae from the middle or end of a long, thin tail that may have been originally made up of more than 25 vertebrae. NPR has a story on how this amber was found. An excerpt from it reads: In 2015, Lida Xing was visiting a market in northern Myanmar when a salesman brought out a piece of amber about the size of a pink rubber eraser. Inside, he could see a couple of ancient ants and a fuzzy brown tuft that the salesman said was a plant. As soon as Xing saw it, he knew it wasn’t a plant. It was the delicate, feathered tail of a tiny dinosaur. Read more of this story at Slashdot.

Cesarean Births Could Be Affecting Human Evolution, Study Says

CanadianRealist writes: Larger babies delivered by cesarean section may be affecting human evolution. Researchers estimate cases where the baby cannot fit down the birth canal have increased from 30 in 1, 000 in the 1960s to 36 in 1, 000 births today, [according to estimates from researchers at the University of Vienna in Austria.] Science Alert reports: “In the past, larger babies and mothers with narrow pelvis sizes might both have died in labour. Thanks to C-sections, that’s now a lot less likely, but it also means that those ‘at risk’ genes from mothers with narrow pelvises are being carried into future generations. More detailed studies would be required to actually confirm the link between C-sections and evolution, as all we have now is a hypothesis based on the birth data.” Agreed, more studies required part. Cesareans may simply be becoming more common with “too large” defined as cesarean seems like a better idea. It’s reasonable to pose the question based simply on an understanding of evolution. Like it’s reasonable to conjecture that length of human pregnancy is a compromise between further development in utero, and chance of mother and baby surviving the delivery.

Nestle Discovers ‘Breakthrough’ Method To Cut Sugar In Chocolate By 40% Without Affecting Taste

Nestle and its scientists have discovered how to “structure sugar differently” to reduce the amount of sugar in some of its products by 40%. What’s more is that it can be done reportedly without compromising the taste. The Guardian reports: The new process is said to make sugar dissolve faster so that even when less is used, the tongue perceives an identical level of sweetness. It plans to patent the process, discovered by its scientists, which it says will enable it to significantly decrease the total sugar in its confectionery products. A four-finger milk chocolate Kit Kat currently contains 23.8g of sugar, a plain (milk chocolate) Yorkie contains 26.9g and a medium peppermint Aero has 24.9g of sugar. If the amount of sugar in each of these products was cut by 40% the new amounts would be 14.3g, 16.1g and 14.9g respectively. Read more of this story at Slashdot.

Facebook Officially Announces Gameroom, Its PC Steam Competitor

An anonymous reader quotes a report from TechCrunch: After losing mobile gaming to iOS and Android, Facebook is making a big push into playing on PC with today’s developer launch of its Gameroom Windows desktop gaming platform. After months of name changes, beta tests and dev solicitation, Facebook opened up the beta build for all developers and officially named it Gameroom. The app is openly available for users to download on Windows 7 and up. Gameroom let users play web, ported mobile and native Gameroom games in a dedicated PC app free from the distractions of the News Feed. Gameroom will have to fight a steep uphill battle again Valve’s Steam platform, which has well over 125 million active users, with millions actually playing at any given moment. Facebook will need to convince developers that Gameroom will share its social network’s massive reach and is therefore worth their while. Then it will have to persuade gamers that a more social experience is worth diving into a new platform. If Facebook succeeds, there are plenty of potential benefits to owning a gaming destination. Facebook announced the launch and name change from “Facebook Games Arcade” today at Unity’s game development platform conference. Unity 5.6 shipping next year will allow devs to export their games directly to Facebook Gameroom, as well as to the WebGL standard. Facebook’s director of global games platform, Leo Olebe, touted how Facebook will feature new games in the Gameroom to give developers a leg up. Read more of this story at Slashdot.

First-Ever Dinosaur Brain Tissue Found Preserved In a Pebble

sciencehabit quotes a report from Science Magazine: A decade ago, a fossil hunter was combing the beach in southeastern England when he found a strange, brown pebble. The surface of it caught his eye: It was smooth and strangely undulating, and also slightly crinkly in some places. That oddly textured pebble, scientists report today, is actually an endocast — an impression preserved in the rock — that represents the first known evidence of fossilized brain tissue of a dinosaur (likely a close relative of Iguanodon, a large, herbivorous type of dinosaur that lived about 133 million years ago). Human brains and bird brains are packed tightly into the brain case, so that their convolutions leave an impression of the inside of the case. But dinosaur (and reptile) brains are more loosely fitted; they are surrounded within the brain case by membranes called meninges, tough sheaths that protect and support the brain. So an endocast of a dinosaur brain might be expected to show those structures — and it did. But beneath them, remineralized in calcium phosphate, the researchers also spied a pattern of tiny capillaries and other cortical tissues — the sort of fabric you’d expect for the cortex of a brain. That those textures were pressed up against the brain case doesn’t necessarily mean that dinosaurs were bigger-brained and smarter than we thought, however: Instead, the dinosaur had likely simply toppled over and been preserved upside down, its brain tissue preserved by surrounding acidic, low-oxygen waters that pickled and hardened the membranes and tissues, providing a template for mineralization. The structure of the brain, studied with scanning electron microscopes, reveal similarities to both birds and crocodiles. The researchers reported their findings in a Special Publication of the Geological Society of London. Read more of this story at Slashdot.

"Splat" of Schiaparelli Mars Lander Likely Found

Long-time Slashdot reader Tablizer quotes Space Flight Now: Views from NASA’s Mars Reconnaissance Orbiter released Friday show the crash site where Europe’s experimental Schiaparelli lander fell to the red planet’s surface from a height of several miles, leaving a distinct dark patch on the Martian landscape…The image from MRO’s context camera shows two new features attributed to the Schiaparelli spacecraft, including a large dark scar spanning an estimated 50 feet (15 meters) by 130 feet (40 meters). Schiaparelli’s ground team believes it is from the high-speed impact of the lander’s main body… A little more than a half-mile (1 kilometer) to the south, a bright spot appears in the image, likely the 39-foot-diameter (12-meter) supersonic parachute and part of Schiaparelli’s heat shield, which released from the lander just before ESA lost contact.” Read more of this story at Slashdot.
