Two males have been indicted Wednesday within the case of a sizzling, airless tractor-trailer rig discovered final month with 53 useless or dying migrants in San Antonio, officers mentioned.

A federal grand jury in San Antonio indicted Homero Zamorano Jr., 46, and Christian Martinez, 28, each of Pasadena, Texas, on counts of transporting and conspiring to move migrants illegally leading to dying; and transporting and conspiring to move migrants illegally leading to critical damage.

Each stay in federal custody with out bond pending trial. Martinez’s legal professional, David Shearer of San Antonio, declined to touch upon the indictments. A message to Zamorano’s legal professional was not instantly returned.

Conviction on the dying counts might end in life sentences, however the Lawyer Basic’s Workplace might authorize prosecutors to hunt dying penalties. The intense bodily damage counts carry sentences of as much as 20 years in jail.

It was the deadliest tragedy to say the lives of migrants smuggled throughout the border from Mexico. The truck had been full of 67 folks, and the useless included 27 from Mexico, 14 from Honduras, seven from Guatemala and two from El Salvador, mentioned Francisco Garduño, chief of Mexico’s Nationwide Immigration Institute.

The incident occurred on a distant San Antonio again street on June 27. Arriving law enforcement officials detained Zamorano after recognizing him hiding in some close by brush, in response to an announcement from the U.S. Lawyer’s Workplace. A search of Zamorano’s cellphone revealed calls with Martinez in regards to the smuggling run.

Surveillance video of the 18-wheeler passing via a Border Patrol checkpoint confirmed the motive force matched Zamorano’s description, in response to the indictment. One survivor of the journey, a 20-year-old from Guatemala, informed The Related Press that smugglers had coated the trailer’s flooring with what she believes was powdered rooster bouillon, apparently to throw off any canine on the checkpoint.

The tragedy occurred at a time when large numbers of migrants have been coming to the U.S., lots of them taking perilous dangers to cross swift rivers and canals and scorching desert landscapes. Migrants have been stopped almost 240,000 instances in Might, up by one-third from a 12 months in the past.

Of the 73 folks within the truck, those that died included folks from the Mexican states of Guanajuato, Veracruz, Oaxaca, Mexico, Zacatecas, Queretaro, Morelos and Mexico Metropolis. Migrants from Honduras and Guatemala additionally have been amongst those that died within the deadliest identified smuggling try in the US.

In 2017, 10 folks died after being trapped inside a truck parked at a San Antonio Walmart. In 2003, the our bodies of 19 migrants have been present in a sweltering truck southeast of the town.

Mexico investigating reports of 17 people shot dead during wake | Crime News


Video shared broadly on social media reveals individuals lined up towards a wall in Michoacan state earlier than gunshots ring out.

Mexico is investigating reviews that round 17 individuals have been executed within the state of Michoacan, after a ugly video confirmed gunmen storming a funeral wake in the course of the weekend and dragging mourners outdoors to be killed.

Mexico’s President Andres Manuel Lopez Obrador on Monday urged persistence because the chief prosecutor’s workplace investigates what occurred, saying that he hoped “with all of his soul” that the occasions weren’t true.

“We nonetheless don’t have all the data,” Lopez Obrador mentioned throughout his every day morning press convention, including that shell casings have been discovered however no our bodies.

A video shared broadly on social media confirmed a gaggle of individuals lined up towards a wall, most of them holding their arms behind their heads, earlier than apparently being shot in a barrage of bullets fired by surrounding gunmen.

Mexican media reported the mourners have been killed within the city of San Jose de Gracia, some 200km (125 miles) west of Morelia, the state capital of Michoacan, the place turf battles between rival drug cartels have despatched violence hovering.

The Michoacan chief prosecutor’s workplace late on Sunday mentioned that although no our bodies have been discovered, investigators found firearms cartridges on the website the place the video was suspected to have been filmed in addition to “cleansing merchandise” in a bag, saying the “website had just lately been washed”.

The video on social media seems to have been filmed by a close-by neighbour by way of a window with a excessive vantage level, displaying the group of individuals lined up towards a white wall.

A number of gunmen are seen pointing rifles on the purported mourners till gunfire prompts the individual filming to cover for a few seconds.

When the uninterrupted video returns to indicate the identical spot on the road once more, the individuals can not be seen and there’s solely smoke and mud rising within the air.

Violence has elevated in sure components of Mexico the place drug cartels battle for management over trafficking routes and territory to extort residents. Concentrating on funeral wakes has turn out to be a part of the violence lately.

The incident occurred in a area the place the Jalisco New Era (CJNG) cartel, the New Michoacan Household and Los Caballeros Templarios function and have been preventing turf wars.

Earlier this month, 9 individuals have been killed in a single day when gunmen within the northern border metropolis of Ciudad Juarez killed three individuals on the wake of a person who died in jail, after which one other six on the similar man’s funeral later within the day.

In January of final 12 months, gunmen burst right into a wake within the central Mexican metropolis of Celaya and shot useless 9 individuals.

Citing official figures, native media reported that in 2021 the state of Michoacan ranked third within the nation for the best variety of homicides, with 2,732 murders.

Nationally, Mexico registered 33,308 homicides in 2021, after the 2 most violent years in its historical past; 34,554 murders have been reported in 2020 whereas 34,690 happened in 2019.

X-ray technique reveals irregularities and dead spots arise due to incomplete lithium stripping from anode during battery discharge — ScienceDaily


Pure lithium metallic is a promising alternative for the graphite-based anodes at present utilized in electrical car batteries. It might tremendously scale back battery weights and dramatically lengthen the driving vary of electrical automobiles relative to present applied sciences. However earlier than lithium metallic batteries can be utilized in automobiles, scientists should first determine easy methods to lengthen their lifetimes.

A brand new examine led by Peter Khalifah — a chemist on the U.S. Division of Vitality’s (DOE) Brookhaven Nationwide Laboratory and Stony Brook College — tracked lithium metallic deposition and removing from a battery anode whereas it was biking to search out clues as to how failure happens. The work is printed in a particular challenge of the Journal of the Electrochemical Society honoring the contributions of Nobel Prize-winning battery researcher John Goodenough, who like Khalifah is a member of the Battery 500 Consortium analysis crew.

“In a very good battery, the speed of lithium plating (deposition) and stripping (removing) would be the similar in any respect positions on the floor of electrodes,” Khalifah stated. “Our outcomes present that it is more durable to take away lithium at sure locations, which implies there are issues there. By figuring out the reason for the issues, we are able to determine easy methods to eliminate them and make higher batteries with greater capacities and longer lifetimes.”

Khalifah and his collaborators performed the examine utilizing intense x-rays on the Superior Photon Supply, a DOE Workplace of Science person facility at DOE’s Argonne Nationwide Laboratory. They tracked lithium because it shuttled from cathode to anode and again throughout one full cost and discharge cycle.

“The x-rays can see proper by way of the battery and permit us to make many measurements in a short time to trace what occurs because the battery adjustments,” Khalifah stated. “To the very best of our information, nobody has ever been ready to make use of x-rays to map lithium shuttling whereas it occurs.”

One problem: Lithium atoms are troublesome to see utilizing x-rays. The weak sign from the small variety of lithium atoms that transfer between the cathode and anode can simply get obscured by stronger alerts emitted by different supplies that make up the battery — together with the sign that will come from the massive quantity of lithium on a pure lithium metallic anode.

To deal with that problem, Khalifah’s crew designed a battery cell utilizing a “naked” anode — at the very least naked with respect to the presence of pre-existing lithium. This makes the sign of the shuttling lithium ions simpler to measure. They then did a examine evaluating two completely different anode supplies — copper and molybdenum — on which lithium ions have been deposited as pure lithium metallic after being extracted from the cathode materials throughout operation of those batteries. This allowed the researchers to observe how uniformly lithium metallic was added to and faraway from anode surfaces. Evaluating this course of utilizing copper and molybdenum anodes additionally supplied a possibility to determine variations between these two metals that may show fruitful in designing improved batteries. Utilizing this setup, the crew mapped out how a lot lithium was current throughout the electrode whereas the cell was maintained at numerous levels of cost and discharge.

It took about an hour to gather maps with tons of of information factors. That mapping information may very well be used to determine adjustments that had occurred because of charging and discharging the battery, however the course of of information assortment was too sluggish to be helpful for following the adjustments as they occurred. So, to trace adjustments as they occurred, the scientists used a extra speedy information assortment process to scan a small subset of 10 pixel-specific areas over and over throughout battery biking.

“We made the maps whereas the battery was in a resting state, beginning at zero capability, then took pixel measurements as we charged to half capability. Then we stopped charging and made one other map, then resumed pixel-specific measurements whereas charging to full capability. We then discharged the cell whereas persevering with to alternate mapping and pixel scans, stopping to gather maps at half discharge and full discharge,” Khalifah defined.

Outcomes reveal variations

For the copper anode, all of the factors behaved as they need to throughout charging: half the lithium capability was deposited on the anode as much as the half-charged state, and all potential lithium was deposited by the complete cost state.

On discharge, massive variations developed between pixels. In some pixels, the lithium was eliminated proportional to the discharge (half the lithium was stripped by the half discharge state, and all was passed by full discharge). Different pixels confirmed a lag in lithium removing, the place stripping was sluggish throughout the first half of discharge, then sped as much as full the method by full discharge. In nonetheless different spots the lagging was so extreme that a lot of the lithium remained on the anode even when the battery had been absolutely discharged.

“If the lithium is left behind, that reduces the capability of the cell,” Khalifah stated. “Every lithium atom left behind means one much less electron flowing by way of the exterior circuit powered by the battery. You may’t extract all of the capability of the cell.”

The discovering that these irregularities arose resulting from incomplete stripping of lithium was considerably shocking. Previous to this examine, many scientists had believed that lithium plating was the supply of the worst issues in lithium metallic batteries.

“Normally, one expects it’s harder to deposit lithium metallic because the atoms should be organized within the particular association of the crystal construction of this metallic,” Khalifah defined. “Eradicating lithium must be simpler as a result of any atom on the floor will be taken away with out having to observe any particular sample. Moreover, if lithium is added extra rapidly than the atoms will be deposited homogenously throughout the floor, the expansion tends to happen within the type of needle-like dendrites that may trigger electrical shorts (and probably fires) within the battery.”

The molybdenum anode confirmed a bit extra variation throughout plating than copper, however much less variation throughout stripping.

“Because the lithium habits was higher throughout the stripping step that precipitated probably the most general irregularities within the anode, it implies that batteries utilizing molybdenum foil substrates as an alternative of copper substrates may yield greater capability batteries,” Khalifah stated.

Nonetheless, it isn’t but clear if the selection of metallic is chargeable for the higher efficiency of the molybdenum anode. One other issue may very well be the distribution of electrolyte — the liquid by way of which the lithium ions journey as they shuttle backwards and forwards between anode and cathode.

The mapping information confirmed that the areas of poor efficiency occurred in spots that have been about 5 millimeters throughout. The dimensions and form of these spots and comparisons with different experiments counsel that poor spreading of the liquid electrolyte all through the battery cell may be chargeable for the native lack of capability in these areas. If that is so, Khalifah stated, then the efficiency of the battery can seemingly be improved by discovering a greater technique for distributing the electrolyte throughout the cathode.

“Comply with-up experiments aimed toward distinguishing between metallic and solvent results, and for testing the effectiveness of methods for mitigating potential issues corresponding to electrolyte inhomogeneity, will assist advance the broader purpose of growing high-capacity lithium metallic anode batteries with lengthy lifetimes,” Khalifah stated.

John McAfee Dead In Spain After Extradition Ruling


John McAfee, the eccentric tech mogul who made his fortune creating antivirus software program, was discovered lifeless in a jail cell close to Barcelona on Wednesday, simply hours after Spain’s Nationwide Court docket dominated that he was to be extradited to the USA to face tax evasion costs. He was 75.

The information of his demise was first reported by El Pais, who stated he died by suicide. An official then confirmed the information of his demise to the Related Press, with an announcement from the Catalan authorities saying a 75-year-old US citizen awaiting extradition couldn’t be resuscitated.

McAfee was arrested final October in Spain, charged with failing to pay tens of millions of {dollars} in revenue taxes from 2014 to 2018 in Tennessee. He additionally confronted costs from Manhattan federal investigators over his involvement in a “pump and dump” cryptocurrency scheme.

Earlier on Wednesday, the Spanish court docket dominated McAfee would face extradition, after months of him claiming that the costs towards him have been politically motivated and designed to make sure he by no means left jail once more.

The tax evasion costs weren’t the primary time McAfee had been linked to a felony investigation. In 2012, McAfee was wished for questioning in Belize over the homicide of his neighbor.

For months, McAfee had been tweeting from jail.
