The researchers started by showing that the same is true in insects. Initially, they worked with everyone's favorite fruit fly, Drosophila, showing that the equivalent genes responded in the same ways in the flies. They then showed that the innate immune response isn't activated when these same flies are exposed to an infection. A different class of insecticide (an organophosphate) had a much weaker effect on the fly's innate immunity. With the molecular activity well characterized, they went on to demonstrate that the same effects could be seen in bees. … [Read more...] about An insecticide-infection connection in bee colony collapses

Wemo Mini smart plug - $16.99 (from $25) The Wemo Mini smart plug is down to $16.99 on Amazon. The plug normally goes for as much as $25 and was selling for around $20 for most of the holidays. The drop to $17 is only the third time in the last year it has gone below $20 at all and is just a buck or two from its lowest drop ever. Amazon is actually price matching Best Buy's deal of the day, so you can find the price over there as well. Today's deal will only last through the end of the day. … [Read more...] about Sunday’s top deals: Dash cams, smart plugs, Bluetooth headphones, and more!
WiGig on the 60GHz band has its own Wi-Fi protocol, known as 802.11ad. The latest Wi-Fi protocol for general use is 802.11ac, which uses the 5GHz band and can power throughput of more than a gigabit per second. Qualcomm's tri-band chips will combine these two protocols along with the older 802.11b/g/n ones that operate on 2.4GHz spectrum. Qualcomm said that this combination will "coupl[e] the whole home coverage of 11ac with the in-area multi-gigabit connectivity of 11ad." WiGig is technically capable of 7Gbps speed (although Wilocity's early chips hit a maximum of 4.6 Gbps). Wilocity is expected to ship a 4.6Gbps smartphone chip this year. … [Read more...] about Tri-band Wi-Fi chips for multi-gigabit streaming coming from Qualcomm
So far, Comcast has provided IPv6 connectivity only to Windows Vista/7 and OS X 10.7 users who connect their computer directly to a DOCSIS 3 cable modem. But they're now also going to delegate an entire range of IPv6 addresses to IPv6-capable home routers, which can then hand out these addresses on their LAN ports and over Wi-Fi. And IPv6-support is even coming to selected DOCSIS 2 modems. Both cable operators will be giving out /64 prefixes, which is the size used on a single subnet. In other words: you can't daisy chain home routers or have separate IPv6 home and office networks separated by a router or firewall. The rationale for this decision is that some home routers may be confused by a larger address block, and current ones have no use for such a bigger block, anyway. But bigger address blocks may be given out at some point in the future. … [Read more...] about With World IPv6 Launch, IPv6 on by default will be the new normal
This model is equipped with three HDMI ports, including one with ARC, along with USB, composite input, antenna/cable input, digital output (optical), Ethernet, and an audio output. Insignia also includes a limited one-year warranty with its purchase. Once you've got an antenna plugged in to receive free TV channels in your area and have subscribed to a few streaming services, you'll hardly miss cable — and you definitely won't miss the monthly bill. … [Read more...] about Insignia’s 55-inch 4K UHD Smart Fire TV reaches one of its best prices yet at $290
