A close study of the hunger hormone ghrelin shows that it affects how frequently animals eat; without it, they may forget when they last ate — ScienceDaily

A hormone that influences when and how frequently animals eat also appears to affect memory, USC scientists have found.

The study was published in the journal Current Biology on Sept. 17.

Animals and humans have the hormone ghrelin in their stomachs. Ghrelin tells animals, as well as humans, when they are hungry and helps regulate their metabolism, but scientists have never been certain how exactly it works.

To learn more about how ghrelin influences hunger, metabolism and memory, researchers at the USC Dornsife College of Letters, Arts and Sciences collaborated with international scientists on a study on rats.

They disrupted the ability of the ghrelin hormone to communicate to the vagus nerve, a nerve that signals from the gut to the brain, and then monitored the impact on their feeding and cognitive behaviors.

The rats were not anxious, but they began eating more frequently, said the study’s lead and corresponding

Forget Snowflake, These 3 Tech Stocks Are Better Buys Right Now

Snowflake (NYSE:SNOW), a cloud data company, has received a lot of attention from investors lately, following its mid-September IPO. Investors have taken an interest in this tech stock because of its 133% revenue growth in the first half of this year, and the fact that the company believes it has a massive $81 billion total addressable market in the cloud data space. 

But despite Snowflake’s potential, there are a handful of other tech stocks that could be better long-term investments. To help you find a few, we asked three Motley Fool contributors for alternative Snowflake investments. They came back with Alteryx (NYSE:AYX), Zoom Video Communications (NASDAQ:ZM), and Amazon.com (NASDAQ:AMZN). Here’s why.

Forget Apple: Buy This Tech Stock Instead

Apple is a phenomenal company by just about every measure. But with a market capitalization around $2 trillion, it’s massive size makes it less appealing to investors who are looking to put their money into companies with long runways for growth.

If that’s the sort of stock you’re interested in adding to your portfolio, you may want to consider Lemonade (NYSE:LMND), a small, tech-forward insurance provider that has some of the same characteristics that made the iPhone maker an incredible investment.

It’s innovative

“The people who are crazy enough to think they can change the world are the ones who do.” — Steve Jobs, Apple co-founder and former CEO

Innovation has always been at the core of Apple’s DNA, and it’s central to Lemonade’s, too. Co-founders Daniel Schreiber and Shai Wininger have set about to upend the centuries-old insurance business model with an operation built from scratch on the

Stunning New Surface Pro X Will Make You Forget Apple’s MacBook

Microsoft has updated its Surface line-up with two challengers taking on key parts of the market. The Surface Laptop Go takes on the mid-range Windows 10 laptop space, while the updated Surface Pro X pushes Microsoft’s plans for Windows 10 on ARM

With Apple set to launch its own ARM-powered MacBook, who has the advantage in this new frontier?

Let’s start with the Pro X. Last year’s Surface Pro X, the first ARM-powered Surface machine, was aiming at a particular group of customers. 2020’s Pro X update hasn’t changed this approach.

The Pro X family is for those looking for a highly mobile device, with 4G LTE connectivity, long battery life, and a focus on productivity. It remains a superb client for cloud based services be they from Microsoft or other providers. If your work revolved around Microsoft Office, Teams, Slack, and web-based tools,

Forget Hot IPOs, Buy These Top Tech Stocks Instead

With the tech industry flying high amid the pandemic, the pace of new IPOs and interest in them has been fast and furious. Recent debuts have set a new bar for ludicrous valuation. Snowflake (NYSE:SNOW), for example, is trading for well over 100 times trailing-12-month revenue — a price tag that assumes flawless execution of its growth strategy in the cloud industry, and then some.

There are more timely purchases out there, though. Three Fool.com contributors think Veeva Systems (NYSE:VEEV), Spotify (NYSE:SPOT), and Alphabet (NASDAQ:GOOGL)(NASDAQ:GOOG) are worth some of your money right now.

Nicholas Rossolillo (Veeva Systems): First off, I need to acknowledge my pick is no value. On the contrary, cloud computing technologist Veeva Systems trades for 31 times trailing-12-month revenue and 28 times expected fiscal year 2021 (the 12 months ended Jan. 31,

Privacy is the big thing that gives people the heebie-jeebies when it comes to digital assistants like Alexa. But at Amazon’s devices and services event today, the company announced it was expanding privacy settings with regard to voice recordings.

Later this year, you’ll be able to say, “Alexa, delete everything I’ve said.” According to Amazon, that command will then delete all previously saved voice recordings associated with your account. But, wait, didn’t Amazon already let you do that before? What gives?

Previously, you had to navigate through labyrinthian menu settings to find the page where you could review and delete any recordings. Then, in 2019, Amazon introduced the ability to say “Alexa, delete what I just said,” to erase your last request. You could say “Alexa, delete everything I said today.” While a nice improvement, it wasn’t completely foolproof. Gizmodo found

Forget Facebook: Google ducks scrutiny on election misinformation, ads

  • As tech companies gear up to fight misinformation ahead of the 2020 elections, Facebook has received the most scrutiny amid a steady flow of reporting that highlights its missteps.
  • Meanwhile, researchers say Google has been “getting a pass on transparency” by hiding behind Facebook and being less willing to share data about its own products, specifically around political advertising.
  • Google is the largest digital ads company and plays a key role in what advertisements millions of Americans see while watching YouTube, viewing search results, and across the internet about the electoral candidates, issues, and voting.
  • Google said it’s “committed to delivering the highest standards in transparency, choice and controls” by verifying advertisers, banning narrowly targeted ads, and making ad details available in a public archive.
  • But researchers argued that Google’s rules around political ads don’t go far enough, and a less robust ad archive means they — and the public
