Neuroscientists have figured out how your brain wakes you up

Posted by in categories: biotech/medical, neuroscience

You may not realise it when your alarm clock forces you into a bleary-eyed stupor first thing in the morning, but there’s actually a complex chemical process going on inside your brain as you wake up. And scientists now think they’ve identified the part of the brain that ends periods of light sleep and brings us into a state of wakefulness.

Researchers from Switzerland focussed their attention on a specific neural circuit located between the brain’s hypothalamus and thalamus. By stimulating this circuit with pulses of light in a group of mice, the academics could prompt rapid awakenings from sleep and then cause prolonged wakefulness.

Why should we be excited about knowing more about how we get yanked out of our regular sleep patterns? The researchers say it could ultimately help those who are trapped in a long-term coma or vegetative state, and on the flip side, could also help those with sleep disorders, or at least give doctors a better idea of why they aren’t sleeping correctly.

Painless electrical zaps may replace dental anesthesia needles

Posted by in categories: biotech/medical, materials

As much as some people fear getting dental fillings or root canals, what many of them are really afraid of is the needle that delivers the anesthetic into the mouth tissue. Even though the skin in the “jabbing area” is usually pretreated with a topical anesthetic, it can still hurt. Before long, however, a shot of electricity could make that topical treatment deep-acting enough that the needle isn’t even needed.

In a recent study, scientists from the University of Sao Paulo in Brazil combined two commonly-used anesthetic drugs – prilocaine hydrochloride and lidocaine hydrochloride – with a polymer to form a hydrogel. The polymer was included to make it sticky, so that it could be applied to the lining of a pig’s mouth.

Using a process known as iontophoresis, a mild and painless electrical current was then passed through the hydrogel. As a result, there was a 12-fold increase in how well the prilocaine hydrochloride permeated through the tissue. The anesthetic effect was claimed to be not only fast-acting, but also long-lasting.

LinkNYC’s free gigabit Wi-Fi is here, and it is glorious

Posted by in categories: economics, habitats, internet, mobile phones

I’m standing on the corner of 15th Street and Third Avenue in New York City, and I’m freezing. But my iPhone is on fire. After connecting to one of LinkNYC’s gigabit wireless hotspots, the futuristic payphone replacements that went live for beta testing this morning, I’m seeing download speeds of 280 Mbps and upload speeds of 317 Mbps (based on Speedtest’s benchmark). To put it in perspective, that’s around ten times the speed of the average American home internet connection (which now sits at 31 Mbps). And to top it all off, LinkNYC doesn’t cost you a thing.

God Does Not Deserve Admiration

Posted by in category: ethics

God does not exist. However, let’s grant for a moment that God is real. Religious texts and practices show that God is wicked, cruel, and immoral, and totally unworthy of affection by moral human beings.

For the sake of brevity, we’ll exclusively consider the God of the New Testament, and ignore the God of the Old Testament, Koran, and other books. This God is often portrayed as hip, cool, and loving. If we dig deeper into some of the basic tenets of Christianity held by mainstream Protestant, Catholic, and Orthodox churches, we’ll see that it’s an elaborate smoke screen. The God of the New Testament is a beast.
