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.

Uber Lost $800 Million In Third Quarter

According to a report from The Information (Warning: paywalled), Uber has lost more than $800 million in the third quarter. CNBC reports: The results, The Information reported, put Uber on pace to record an 25 percent steeper operating loss than last year, of at least $2.8 billion in 2016, before interest, tax, depreciation and amortization. Despite steep results from one of the world’s most valuable start-ups, these results would have been worse if not for a one-time windfall thanks to the sale of Uber’s China business to Didi Chuxing, The Information reported. On the bright side, Uber’s revenue is skyrocketing, and its rate of losses slowed from the prior quarter, The Information said. Still, the report comes as Uber’s multi-billion dollar valuation has come under scrutiny from those who say its business model depends on subsidies and faces looming battles over regulation.

A $300 Device Can Steal Mac FileVault2 Passwords

An anonymous reader writes: Swedish hardware hacker Ulf Frisk has created a device that can extract Mac FileVault2 (Apple’s disk encryption utility) passwords from a device’s memory before macOS boots and anti-DMA protections kick in. The extracted passwords are in cleartext, and they also double as the macOS logon passwords. The attack requires physical access, but it takes less than 30 seconds to carry out. A special device is needed, which runs custom software (available on GitHub), and uses hardware parts that cost around $300. Apple fixed the attack in macOS 10.12.2. The device is similar to what Samy Kamker created with Poison Tap. Read more of this story at Slashdot.

Paris Makes All Public Transportation Free In Battle Against ‘Worst Air Pollution For 10 Years’

Paris has barred some cars from its streets and has made public transportation free as it suffers from the worst and most prolonged winter pollution for at least 10 years, the Airparif agency said on Wednesday. The Independent reports: Authorities have said only drivers with odd-numbered registration plates can drive in the capital region on Wednesday. Drivers of even-numbered cars were given the same opportunity on Tuesday, but could now be fined up to 35 EUR if they are caught behind the wheel. More than 1, 700 motorists were fined for violations on Tuesday. Paris mayor Anne Hidalgo said images of smog blanketing the capital were proof of the need to reduce vehicle use in the city center. The air pollution peak is due to the combination of emissions from vehicles and from domestic wood fires as well as near windless conditions which means pollutants have not been dispersed, the Airparif agency said. “This is a record period (of pollution) for the last 10 years, ” Karine Leger of AirParif told AFP by telephone. For more than a week, Airparif has published readings of PM10 at more than 80 micrograms per cubic meter of air particles, triggering the pollution alert. Along with odd-numbered cars, hybrid or electric vehicles as well as those carrying three or more people will be allowed to roam the roads. Foreign and emergency vehicles will be unaffected.

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.

Qualcomm Debuts 10nm Server Chip To Attack Intel Server Stronghold

An anonymous reader quotes a report from Tom’s Hardware: Qualcomm and its Qualcomm Datacenter Technologies subsidiary announced today that the company has already begun sampling its first 10nm server processor. The Centriq 2400 is the second generation of Qualcomm server SOCs, but it is the first in its new family of 10nm FinFET processors. The Centriq 2400 features up to 48 custom Qualcomm ARMv8-compliant Falkor cores and comes a little over a year after Qualcomm began developing its first-generation Centriq processors. Qualcomm’s introduction of a 10nm server chip while Intel is still refining its 14nm process appears to be a clear shot across Intel’s bow–due not only to the smaller process, but also its sudden lead in core count. Intel’s latest 14nm E7 Broadwell processors top out at 24 cores. Qualcomm isn’t releasing more information, such as clock speeds or performance specifications, which would help to quantify the benefit of its increased core count. The server market commands the highest margins, which is certainly attractive for the mobile-centric Qualcomm, which found its success in the relatively low-margin smartphone segment. However, Intel has a commanding lead in the data center with more than a 99% share of the world’s server sockets, and penetrating the segment requires considerable time, investment, and ecosystem development. Qualcomm unveiled at least a small portion of its development efforts by demonstrating Apache Spark and Hadoop on Linux and Java running on the Centriq 2400 processor. The company also notes that Falkor is SBSA compliant, which means that it is compatible with any software that runs on an ARMv8-compliant server platform. Read more of this story at Slashdot.

Google Says It Is About To Reach 100 Percent Renewable Energy

Google said today it will power 100 percent of its sprawling data centers and offices with renewable energy starting next year. The company said today it has bought enough wind and solar power to account for all the electricity it uses globally each year. In comparison, 44 percent of Google’s power supplies came from renewables last year. From a blogpost: To reach this goal we’ll be directly buying enough wind and solar electricity annually to account for every unit of electricity our operations consume, globally. And we’re focusing on creating new energy from renewable sources, so we only buy from projects that are funded by our purchases. Over the last six years, the cost of wind and solar came down 60 percent and 80 percent, respectively, proving that renewables are increasingly becoming the lowest cost option. Electricity costs are one of the largest components of our operating expenses at our data centers, and having a long-term stable cost of renewable power provides protection against price swings in energy.

Netflix Keeping Bandwidth Usage Low By Encoding Its Video With VP9 and H.264/AVC Codecs

Netflix announced last week that it is getting offline video downloads support. The company has since shared that it is using VP9 video compression codec to ensure that the file sizes don’t weigh a lot. An anonymous reader shares an article on Slashgear (edited): For streaming content, Netflix largely relies on H.264/AVC to reduce the bandwidth, but for downloading content, it uses VP9 encoding. VP9 can allow better quality videos for the same amount of data needed to download. The challenge is that VP9 isn’t supported by all streaming providers — it is supported on Android devices and via the Chrome browser. So to get around that lack of support on iOS, Netflix is offering downloads in H.264/AVC High whereas streams are encoded in H.264/AVC Main on such devices. Netflix chooses the optimal encoding format for each title on its service after finding, for instance, that animated films are easier to encode than live-action. Netflix says that H.264 High encoding saves 19% bandwidth compared to other encoding standards while VP9 saves 36%. Read more of this story at Slashdot.

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.
