Apple Says Third-Generation Keyboards Exclusive to 2018 MacBook Pro

MacRumors - Sun, 2018-07-15 18:34
Last month, Apple initiated a Keyboard Service Program for MacBook and MacBook Pro, after determining that a "small percentage" of the keyboards in 2015-2017 MacBook and 2016-2017 MacBook Pro models may experience keys that feel "sticky," repeat, or do not respond in a consistent manner.


Apple did not identify a cause for the issues, which they call "behaviors," but they're believed to be caused by dust and other particulates becoming stuck in the butterfly switch mechanism underneath keycaps.

Apple has been servicing affected keyboards free of charge, with the process involving the replacement of one or more keys, or the whole keyboard. For the MacBook Pro, the replacements are second-generation keyboards -- often the 2017 variant with slightly different markings on the Control and Option keys.

Then, last week, Apple surprised us with new 2018 MacBook Pro models that feature an "improved third-generation keyboard for quieter typing." These models are not eligible, at least not now, for Apple's service program.

Apple hasn't directly acknowledged whether the quieter, third-generation keyboards dually address the keyboard issues, but iFixit discovered the 2018 MacBook Pro has a thin, silicone barrier underneath each key, which they believe are intended to prevent the dust and crumbs from getting stuck.

For this reason, some customers have been hoping that Apple will start swapping out second-generation keyboards with third-generation keyboards, as part of its service program, but MacRumors has learned that isn't the plan.

When asked if Apple Stores and Apple Authorized Service Providers will be permitted to replace second-generation keyboards on 2016 and 2017 MacBook Pro models with the new third-generation keyboards, if necessary, Apple said, no, the third-generation keyboards are exclusive to the 2018 MacBook Pro.

Hopefully, in that case, it means that Apple has quietly tweaked the second-generation keyboard to be more reliable. It wouldn't really make sense for Apple to replace keyboards with ones that are just as prone to break again, especially if the third-generation keyboards offer a fix.

One possibility is that the third-generation keyboards aren't backwards compatible with 2016 and 2017 MacBook Pro models to begin with. The keyboard is actually one part of a larger component called the "top case," which has a glued-in battery, and this part may have changed slightly in 2018 models.

Of course, it is possible that a few customers who send in their 2016 or 2017 MacBook Pro may end up with a third-generation keyboard in rare circumstances, should it prove to be compatible, at the discretion of Apple Stores and Apple Authorized Service Providers. We'll have to wait and see.

To initiate a repair, head to the Contact Apple Support portal, select Mac → Mac notebooks → Hardware Issues → Keyboard not working as expected → Bring in for Repair and book an appointment with an Apple Store or Apple Authorized Service Provider. Remember to back up your Mac before any servicing.

Half of parents talk on the phone while driving kids

Futurity.org - Sun, 2018-07-15 18:15

In the previous three months, about half of parents talked on a cell phone while driving with their kids in the car, research finds. The researchers also report that one in three read text messages, and one in seven used social media.

The study also found a correlation between cell phone use while children were in the car and other risky driving behaviors, such as not wearing a seat belt and driving under the influence of alcohol whether or not children were present in the car.

“…risky driving behaviors rarely occur in isolation…”

Crash fatalities and injuries resulting from distracted driving constitute a public health crisis in the US, resulting in about one in four motor vehicle crashes. Previous research suggests that causes of distracted driving by parents and caregivers include talking on hand-held or hands-free cell phones or using phones to text, email, or access the internet.

Researchers wanted to identify specific factors associated with cell phone-related distracted driving in parents and caregivers of children between the ages of 4 and 10.

“Technology has become increasingly intertwined with our daily lives,” says lead author Catherine McDonald, a senior fellow with the Children’s Hospital of Philadelphia’s Center for Injury Research and Prevention and an assistant professor of nursing at the University of Pennsylvania School of Nursing.

“The results from this research reinforce that risky driving behaviors rarely occur in isolation, and lay the groundwork for interventions and education specifically aimed at parents who drive with young children in their cars.”

Calling, texting, posting online

The study, published in the Journal of Pediatrics, involved an online sample of 760 adults from 47 US states. The respondents had to be at least 18 years old, a parent or routine caregiver of a child between the ages of 4 and 10, and had driven their oldest child between those ages at least six times in the preceding three months.

The research finds a direct correlation between a history of driving under the influence and increased likelihood of all types of cell phone use while driving with kids in the car.

In the preceding three months, 52.2 percent of parents had talked on a hands-free phone while driving with a young child in the car, while 47 percent had done so with a hand-held phone. The study also found that 33.7 percent of parents read text messages while 26.7 percent sent text messages while driving with children. Social media also contributed to distracted driving, with 13.7 percent of respondents reporting using social media while driving with children.

The study also looked at child restraint system (CRS) use for children in the same age group. The study found that 14.5 percent of parents did not consistently use their typical CRS when driving with their children. Drivers who did not consistently use their typical CRS were more likely to engage in cell phone use while driving.

Impaired driving in the past

Finally, the study looked at parent and caregiver risky behavior associated with driving, including not wearing a seat belt as a driver and driving under the influence of alcohol, whether or not their children were in the car. The researchers saw a direct correlation between a history of driving under the influence and increased likelihood of all types of cell phone use while driving with children in the car.

To reform risky drivers, target specific crimes

All cell phone-related distracted driving behaviors other than talking on a hands-free phone increased if a person did not always wear their seat belt while driving with children.

McDonald says that future studies are needed to understand if unsafe distracted driving behaviors by parents influences their children as they become young drivers in the future.

‘Rope-jumping’ rotor could pave way for molecular machines

Futurity.org - Sun, 2018-07-15 18:15

Researchers have created a new type of molecular rotor that shows promise for future development as a functional machine capable of manipulating matter at atomic and subatomic levels.

The research could transform multiple branches of chemistry, along with myriad related sectors and industries, they say.

The researchers used a method called olefin metathesis recognized with the 2005 Nobel Prize in Chemistry to synthesize a series of platinum complexes with macrocyclic ring ligands that can flip over the core platinum atom in a conformation change reminiscent of Double-Dutch rope jumping. The researchers overcame significant synthetic challenges to achieve unprecedented molecular motions, often centered on a core rotation that evokes a triple axel skating jump.

In addition to characterizing the new molecules using various physical methods, the researchers used computational methods available through the Laboratory for Molecular Simulation (LMS) as well as supercomputing and data-analysis technology to further understand the motions these molecules can undergo.

“Similar compounds have been reported before but with only one macrocyclic ring,” says Andreas Ehnbom, who works with research leader John A. Gladysz, professor of chemistry at Texas A&M University.

“Ours have three rings and therefore can undergo a ‘triple-jump-rope’ mechanism, which is unprecedented,” adds Hemant Joshi, a postdoctoral researcher.

Molecular machines—tiny structures with controllable movements that can perform a variety of tasks when energy is added to the equation—made major headway and headlines as the subject of the 2016 Nobel Prize in Chemistry.

As versatile as they are mighty, these devices could potentially be employed as molecular switches and motor-molecules and then applied to the fabrication of nanoelectronic devices, nanoelectromechanical systems (NEMS), and drug delivery systems with any number of potential applications in chemistry, materials science and engineering, industry, and medicine.

“Scientists have pursued the synthesis of molecules with architectures that enable controlled movements for a very long time, and it is an increasingly active field of research, as evidenced by the 2016 Nobel Prize,” Gladysz says.

“Using such molecules, it should be possible to design and develop functional molecular machines capable of manipulating matter at the atomic level, which would be revolutionary. We are still far from reaching this goal, but now, we are one step closer.”

Molecules drill into cells to deliver drugs or kill

Ehnbom notes that one important next step will be figuring out how to control the motion of their compounds, which at present is random, not unlike that of real-life engines and motors.

The team plans to use state-of-the-art computational models to simulate such rotation, thereby gaining a better understanding of the factors that control it to further hone their design, from subsequent rotors to experiments. After all, the future—and feasible application—depends on it.

“If researchers ever succeed to synthesize functional molecular machines, the possibilities are endless and range from molecular-level transport, or delivery of medication within the body, to manipulation of microscopic structures, or synthesis of chemicals, to data processing and storage,” adds Sugam Kharel, who just completed his PhD.

The research appears in the Journal of the American Chemical Society.

No, big feelings don’t threaten infertility treatment

Futurity.org - Sun, 2018-07-15 18:00

A woman’s emotional state does not have a strong connection with the success of infertility treatment, according to new evidence.

“Our results offer hope and optimism to the many women who feel emotionally responsible…”

This runs counter to the advice many women struggling with infertility report receiving from family and friends: to “just relax.” This can suggest their mental state is to blame when things don’t work out.

Coauthors Marci Lobel, professor of psychology, Jennifer Nicoloro-SantaBarbara, and colleagues at Stony Brook University report the study results in the journal Social Science and Medicine.

The researchers analyzed more than 20 published studies involving more than 4,000 women to investigate whether women’s emotional distress impedes the success of infertility treatments.

Women coping with infertility want more support, less advice

The results of the analysis indicate that women’s distress, including anxiety and depressive symptoms, is not associated with poor treatment outcomes. These findings held true for women regardless of their age, how long they were infertile, and whether or not they had received treatment for infertility previously.

“Our results offer hope and optimism to the many women who feel emotionally responsible or blame themselves for poor outcomes of infertility treatment,” says Lobel.
