Florida 16-year-old allegedly beats friend to death with a baseball bat over a girl, officials say

A 16-year-old Florida boy is suspected of beating his friend to death with a baseball bat, authorities said, alleging that the teen was jealous of his friend's relationship with a girl.
Police say the suspect persuaded friend Giovanni Diaz, 15, to go into a wooded area Monday afternoon, where the teen "viciously beat and killed Giovanni with a baseball bat," Polk County Sheriff Grady Judd said at a news conference Monday. He hit Giovanni at least nine times, Judd added.
As the suspect emerged from the woods, authorities say he told a witness, "I hit my friend with a baseball bat," according to Sheriff Judd.
The witness told the teen to go home and call 911, Judd said. The suspect did so, allegedly confessing to hitting his friend with the bat, Judd said. After he dialed 911, police say the teen agave an "elaborate" defense about protecting himself, which Sheriff Judd called a lie.  
The teen allegedly told a responding officer that he had "wailed" on his friend with a bat, Judd said, and the suspect was taken into custody.
At a news conference today, Judd called the beating premeditated; he said Giovanni had "relations" with a girl the suspect liked and "that made him mad."
Police say the suspect told someone several days ago, "I wonder what it's like to murder someone," Judd said today.  
The sheriff has released the suspect’s name but ABC News is not naming him because he is a minor.
The suspect is home-schooled while Giovanni, an eighth-grader, attended a middle school, but both lived in the same community, Judd said. The "suspect referred to them as friends," Judd said, adding that they had known each other for a long time.
The alleged victim "has absolutely no previous run-ins with the law," Judd said, but the suspect was charged two years ago with two counts of battery for allegedly battering two people, including Giovanni.
The suspect also was charged with domestic battery last year for allegedly battering his father, Judd said.
The suspect has been charged with one count of first-degree murder and one count of possession of marijuana. Police are requesting that he be tried as an adult; the State Attorney’s Office will make that decision at a later time, Judd said.

An Elementary School Teacher Left a 4-Year-Old Alone So She Could Buy Marijuana, Police Say

Authorities say a Florida elementary school teacher left a 4-year-old child alone while she went to buy marijuana.
A Polk County Sheriff’s Office news release says 26-year old Marsha Dolce was arrested Saturday and charged with child neglect and marijuana possession.
Deputies responded to a Davenport apartment complex Saturday morning and found a 4-year-old child crying outside wearing only a T-shirt and underwear. Dolce, who teaches fourth grade at Laurel Elementary in Poinciana, eventually returned home and told deputies she had left to help a friend with car troubles.
Deputies reported finding marijuana in Dolce’s home, and text messages on her phone indicated that she had gone to nearby Winter Haven hours earlier to buy the drug.
Child welfare officials removed the child from Dolce’s home.
Jail records didn’t list an attorney for Dolce.

CPEC now threatens to destroy our industry by lifting import tariffs, say Pakistani officials

Pakistan slashed import tariffs on 6000 items. Now, there is no need for China to manufacture them in Pakistan, posing a threat to the SEZs set up along CPEC.

The way the China-Pakistan Economic Corridor (CPEC) is progressing is certainly going to end up hurting Pakistan. This is not something we are saying, but the opinion of Pakistan's Federal Board of Revenue (FBR), Pakistan media reports have said. The FBR believes CPEC could well end up destroying Pakistani industry, and take away any incentive for Chinese companies to manufacture in Pakistan.

This round of rising discord within the Pakistani government over the CPEC's negatives outweighing the positives comes as Islamabad removed import tariffs on about 6000 items from China. These 6000 items are part of list of about 7200 articles that are also manufactured in Pakistan.

The waiver on import duties came as part of the second phase of the Free Trade Agreement between China and Pakistan. Maintaining the opacity that has characterised CPEC so far, even governmental organisations like FBR and Pakistan's Board of Investment (BOI) were not informed of the contents of the FTA that has been put in place, major Pakistani dailies Dawn and The Express Tribune have reported.

Officials from the FBR and BOI anonymously expressed alarm to these newspapers, saying the removal of import tariffs would make it completely unnecessary for China to manufacture these items in Pakistan, and that Chinese companies would rather save on the cost of setting up factories and import them anyway. Chinese investments in special SEZ set up along the CPEC route have so far been advertised as a key component of the project, one that would provide employment for local Pakistanis.

Another major concern that the officials expressed was that the move could flood the market with cheap Chinese goods, driving Pakistani manufacturers who make those 6000 items out of businesses in no time. Even if some of them did survive, they just couldn't work up the cost advantage to export anything of significant value to China, the officials said.

After years of blindly praising CPEC as a mutually beneficial project that would raise Pakistan to great riches, there are now a rising number of voices questioning the whole deal. Concerns have focused on a whole range of issues with CPEC, from the opacity surrounding the terms of agreement between the two countries, to the use of Chinese workers instead of Pakistani ones, to the lopsided revenue-sharing from Gwadar Port, and the terms of control of infrastructure projects, among numerous others.

China has also done its fair bit of arm twisting to keep the Pakistanis from airing negative views in public. CPEC is presently the only fully functional part of Chinese President Xi Jinping's ambitious Belt and Road Initiative (BRI), and any discordant notes over it could lead to more troubles for China in other countries.

Origin of life on Earth: Cyanide may have been the key ingredient

A mixture of cyanide and copper, when irradiated with ultraviolet (UV) light, may have produced simple sugars that formed a key ingredient responsible for the origin of life on Earth.

Researchers have come across a strange finding that may explain the origin of life on early Earth – cyanide.

The beginning and the consequent evolution of life on Earth has been under constant scrutiny in the field of science.

In November 2017, a team of researchers from The Scripps Research Institute (TSRI) in the US hypothesized that a chemical reaction called phosphorylation may have been crucial for the assembly of three key ingredients in early life forms.

Now, the study has found that a mixture of cyanide and copper, when irradiated with ultraviolet (UV) light, may have produced simple sugars that formed a key ingredient responsible for the origin of life on Earth.

"One story for the origin of life is what we call the RNA world," said Zoe Todd from the Harvard University in the US.

"In order to make something like an RNA nucleotide, you need these sugars. This shows that process was plausible on the early Earth," said Todd, a researcher in the study published in the journal Royal Society of Chemistry.

When scientists in the UK demonstrated that the system could produce simple sugars such as glycolaldehyde and glyceraldehyde in 2012, it became a key step in showing that the hypothesis was plausible.

Those tests were performed under ideal conditions – with relatively high concentrations of both cyanide and copper, and powerful lamps that generated high-energy, 254-nanometer wavelength light.

However, previous research has shown that early Earth would have experienced a range of wavelengths shorter than typical on the planet's surface today.

Todd and Dimitar Sasselov, a professor at Harvard, set out to test the system under those conditions.

They combined small amounts of cyanide and copper in an airtight quartz container and then hit the solution with lower-intensity light from tunable xenon lamps.

Using prisms, Todd was able to separate the light into different wavelengths and target the system with a specific wavelength for hours at a time before running tests to confirm the reaction was actually taking place.

By adjusting the system based on specific conditions – which molecules are present in an atmosphere and intensity of the UV light produced by nearby stars – researchers could use the system to model whether the reaction could operate on other planets, Todd said.
