The problem with betting on your own team in baseball is that pitchers need rest. Betting the team you manage will win today could cause you to expend an unreasonable amount of effort on this game, costing you multiple other games in subsequent days because your bullpen is completely gassed.

Putin calls Luka with panic in his voice. "You have to give me asylum, they'll be dragging my corpse through the streets of Moscow by morning if you don't!"

Luka replies, "I'm sure I can arrange something. I'll get back to you within the hour."

59 minutes later, Luka calls back. "Relax, Vova. I worked out a compromise. They'll only drag half your body through the streets of Moscow. The other half will be dragged through Kyiv."

The answers should be provided after the due date. If the student failed one or more particular concepts or techniques, why wait until they fail them at an exam to find out? That doesn't mean the instructors need to spend their time checking the homework, it's sufficient for the student to grade their own homework and say "I'm not getting this, I better ask for help".

It would make sense to me if the answer key was posted after the homework came due. The students could grade their own work against the answer key if they choose, and if they consistently got something wrong they could ask about it. This means less work for the instructors while still performing the due diligence of giving the students feedback on the quality of their homework. Those who care will use what is provided. Those who don't, won't.

Submission + - Virus Stole a Human Gene and Won't Let Go of It (nytimes.com)

Submitted by joshuark
joshuark writes: In a new twist on the phrase "going viral" or stealing code, the NYT reports a virus has "stolen" a human gene, and will not let it go. In the article "This Virus Stole a Human Gene and Won’t Let Go of It" reports that scientists have found a human gene lurking in a virus that causes skin infections. Thus using our own DNA to infect us.

The molluscum contagiosum virus, which causes sores on skin, swiped a gene from humans about 100,000 years ago according to a new study.

The way that viruses replicate makes them particularly good at thieving DNA. The viruses infect a cell, then co-opt its machinery by injecting their own genes. Sometimes this process goes awry, and a stretch of the host’s DNA gets bundled into the new viral genes. This molecular error can pose a threat to human health.

Comment The dabblers are wandering off. (Score 1) 152

Is this necessarily a bad thing? For quite some time, coding has been pushed as a way to make yourself marketable. For a lot of people who have no particular passion for it—nor for anything else, which is why they're dabbling in everything—but were only in it because they thought it was a good career move, it is smart to look for greener pastures now. The real question is, what adjacent fields are easy to slide into, but AREN'T equally vulnerable to the unblinking gaze of AI once there is the critical mass to justify the effort? Are there any?

Submission + - New tin-based solar cells trap heat 1,000 times longer, could beat 33% limit. (interestingengineering.com)

Submitted by fahrbot-bot
fahrbot-bot writes: Interesting Engineering is reporting that researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy “hot electrons” by a factor of 1,000 and could push solar cell efficiency beyond the theoretical 33 percent limit.

When sunlight strikes a panel, photons jump-start electrons into action. The most energetic photons create super-charged hot electrons. Theoretically, these high-voltage powerhouses should generate far more electricity, but, in practice, they are fleeting. In fractions of a trillionth of a second, these high-energy particles rapidly cool, dumping their bonus energy as waste heat before ever leaving the solar cell.

“This means that the energy is lost before the hot electron exits the solar cell material,” said Jan Anton Koster, Professor of Physics of Novel Semiconductors and Devices at the University of Groningen.

Using a specialized solar cell material called tin-based perovskite, Loi’s lab performed a feat many thought impossible: she slowed the heat loss down by a factor of 1,000. Suddenly, the extra energy lingered for nanoseconds instead of vanishing in picoseconds.

The study findings were published in the journal ACS Energy Letters.

Submission + - Google fined more than €400m by Irish regulator over its use of location da (theguardian.com)

Submitted by AmiMoJo
AmiMoJo writes: Google has been fined more than €400m (£345m) over the way it processed users’ location data, following claims that the tech giant had manipulated users into agreeing to be constantly tracked on their mobile phones. The fine, imposed by Ireland’s Data Protection Commission (DPC), comes after complaints from multiple European consumer organisations that Google was following every step users took.

The DPC launched its inquiry six years ago and set out to find out whether Google had a valid legal basis for its use of location data. It found that Google users could have been unaware that their location was being used to influence them with adverts or to gather details about their health and interests.

Submission + - The brain is actually two completely separate organs (stanford.edu)

Submitted by Beeftopia
Beeftopia writes: From Stanford Medicine:

"For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years."

The adult brain has three main regions: the forebrain, midbrain and hindbrain. Scientists could never create hindbrain neurons.

"Previous attempts to make hindbrain neurons likely tried to coax forebrain and midbrain progenitors into hindbrain cells, which our study shows is not possible,” said researcher Rayyan Jokhai.

"The researchers’ breakthrough came from studying the earliest moments of embryonic development, during a stage called gastrulation when the body first takes shape. Jokhai and Dundes discovered that the hindbrain follows a separate developmental path, running in parallel to — rather than branching off from — the pathway that creates the forebrain and midbrain."

With this knowledge, researchers were able to create hindbrain neurons.
