Carbon nanotubes may be the key to shrinking down transistors and squeezing more computer power into less space.

Historically, the number of transistors that can be crammed onto a computer chip has doubled every two years or so, a trend known as Moore’s law. But that rule seems to be nearing its limit: Today’s silicon transistors can’t get much smaller than they already are.

Carbon nanotubes may offer a sizable solution. In the June 30 Science, IBM researchers report a carbon-nanotube transistor with an overall width of 40 nanometers — the smallest ever. It’s about half the size of typical silicon transistors.

Researchers have created carbon-nanotube transistors with certain supersmall components before, but the whole package was still bulky, says study coauthor Qing Cao of IBM’s Thomas J. Watson Research Center in Yorktown Heights, N.Y. The new study confirms that, in terms of size, carbon-nanotube transistors can beat out silicon — and that’s no small feat.

A new insect-inspired tiny robot that can move between air and water is a lightweight.

Weighing the same as about six grains of rice, it is the lightest robot that can fly, swim and launch itself from water, an international team of researchers reports October 25 in Science Robotics. The bot is about 1,000 times lighter than other previously developed aerial-aquatic robots. In the future, this kind of aquatic flier could be used to perform search-and-rescue operations, sample water quality or simply explore by air or sea.
To hover, the bot flaps its translucent wings 220 to 300 times per second, somewhat faster than a housefly. Once submerged, the tiny robot surfaces by slowly flapping its wings at about nine beats per second to maintain stability underwater.

For the tricky water-to-air transition, the bot does some chemistry. After water has collected inside the machine’s central container, the bot uses a device to split water into hydrogen and oxygen gas. As the chamber fills with gas, the buoyancy lifts the vehicle high enough to hoist the wings out of the water. An onboard “sparker” then creates a miniature explosion that sends the bot rocketing about 37 centimeters — roughly the average length of a men’s shoe box — into the air. Microscopic holes at the top of the chamber release excess pressure, preventing a loss of robot limbs.
Still, the design needs work: The machine doesn’t land well, and it can only pierce the water’s surface with the help of soap, which lowers the surface tension. More importantly, the experiment points to the possibilities of incorporating different forms of locomotion into a single robot, says study coauthor Robert Wood, a bioengineer at Harvard University.

Kyle Rittenhouse has been found not guilty.

A jury in Kenosha, Wisconsin, on Friday found Rittenhouse not guilty of homicide and other charges.
On Aug. 25, 2020, Rittenhouse shot at four men, killing two and wounding a third, with a semiautomatic rifle. Rittenhouse was in downtown Kenosha to protect a car dealership during unrest following the police shooting of Jacob Blake.
Blake, a Black man, had been shot multiple times by Rusten Sheskey, a white police officer, in Kenosha, leaving him paralyzed from the waist down. Sheskey was ultimately not charged by state or federal prosecutors.

Rittenhouse, then a 17-year-old from Antioch, Ill., joined a group of other armed people in downtown Kenosha. He shot Joseph Rosenbaum, Anthony Huber and Gaige Grosskreutz, the latter of whom survived. Rittenhouse turned himself in to police in Antioch on Aug. 26, and was extradited to Kenosha, where he was charged with the following:

First-degree reckless homicide, use of a dangerous weapon
First-degree recklessly endangering safety, use of a dangerous weapon
First-degree intentional homicide, use of a dangerous weapon
Attempted first-degree intentional homicide, use of a dangerous weapon
First-degree recklessly endangering safety, use of a dangerous weapon
Possession of a dangerous weapon by a person under 18 (later dismissed)
Failure to comply with an emergency order from state or local government (later dismissed)
Most of the incident was captured on video, and the subsequent trial became heavily polarized. The prosecution in the case argued that Rittenhouse provoked protesters before shooting at them, while the defense argued that Rittenhouse acted in self defense.

The Milwaukee Bucks are scheduled to play at home tonight at 8 p.m. ET/7 p.m. CT. The Bucks, who play 40 miles from Kenosha, were the first NBA team to boycott following the protests in the summer of 2020.

Following the verdict in the case that captured national attention, the sports world responded to the news that Rittenhouse was ruled not guilty.

Prior to the 2021-22 season, the NBA's historic 75th season, Stephen Curry was hot on the heels of Hall of Famer Ray Allen to become the all-time leader for most 3-pointers made.

Entering the season, Curry needed 142 3-pointers needed to surpass Allen, and 12 games into the season, he's knocked off 76 of the latter's lead.
It's still early but Curry is averaging a career-high 5.4 makes per game, a shade above his previous career-high of 5.3 which he set last year in 63 games. During the 2015-16 season in which he set the all-time single-season record with 402 en route to winning his second straight MVP award, Curry averaged 5.1 makes in 79 games.
Top 10 players on the all-time leader for most made 3-pointers
Curry is one of three active players in the Top 10 with James Harden and Damian Lillard being the other two players.

 Player  3-pointers

1. Ray Allen 2,973
2. Stephen Curry 2,908
3. Reggie Miller 2,560
4. James Harden 2,489
5. Kyle Korver 2,450
6. Vince Carter 2,290
7. Jason Terry 2,282
8. Jamal Crawford 2,221
9. Paul Pierce 2,143
10. Damian Lillard 2,087
    LeBron James, who ranks 11th, could break into the Top 10 and increase the list to four active players later this season.

When will Stephen Curry surpass Ray Allen?
Curry has hit 42 of the 76 3-pointers in just five games including a red-hot shooting game against the LA Clippers, where he erupted for 45 points that started with a perfect 25-point first quarter and an overall 8-of-13 efficiency from beyond the arc and a 50-piece against the Atlanta Hawks.

As of Nov. 16, the baby-faced assassin, who is considered to be the greatest 3-pointer shooter in NBA history, needs 76 more 3-pointers to overtake Allen.
Going by his season average of 5.4 3-pointers per game, Curry would take anywhere around 14 games to jump to the No. 1 spot on the all-time charts.

That many games mean Curry could make NBA history in mid-December, provided of course that he misses no games moving forward.

Warriors upcoming 2021-22 schedule
With that projection, Curry would likely make NBA history on the road as Golden State would be on a five-game Eastern Conference road trip in mid-December.

14 games ahead on the Warriors schedule will see the team in Indiana, the birthplace of basketball. 15 games ahead will see the Warriors at the iconic Madison Square Garden playing the Knicks.

In case Curry takes a couple more games to surpass Allen, he has a couple of more iconic locations awaiting him in Boston - home of one of the oldest franchises which is tied for the most champions in NBA history - and Toronto - the capital of the birth country of James Naismith, the sport's inventor.
