The Wolf Forgiveness Bonus Program aims to reduce the number of wolves killed near livestock farms.
The group Howling for Wolves is offering farmers up to $750 for each cow killed by a wolf in Minnesota, in addition to state reimbursement payments, but only if the livestock owner doesn’t call-in federal trappers to kill the wolf.
HOPKINS, Minn. — Every year in Minnesota, upward of 150 wolves are trapped and killed under a federal program to reduce predation on livestock at northern Minnesota farms and ranches.
But the group Howling For Wolves is offering farmers extra cash if they choose not to call in the federal government to do the trapping.
The Wolf Forgiveness Bonus Program, announced Tuesday, would pay livestock owners $600 per calf and $750 per adult cow…

Philadelphia health officials are confirming at least four deaths related to recent extreme heat. According to a Department of Public Health spokesperson, heat was the main factor in one person’s death and contributed to three others.
The four deaths are all listed as accidental in nature. Two of the victims suffered from heart disease, while another one died from drug intoxication with heat playing a factor. The department declined to release the ages of the deceased. Here are details as provided by the Philadelphia Department of Public Health:
A Japanese city has been forced to hire a special unit to hunt troops of aggressive monkeys that have been terrorizing residents for weeks — with the savage simians even sneaking into people’s homes and trying to snatch babies.
At least 58 people have been attacked by the primates — Japanese macaques — in Yamaguchi, a city about two hours west of Hiroshima, since July 8.
According to reports, the macaques aren’t interested in food, so traps haven’t worked. They have targeted…

Larry Rudolph, the multi-millionaire dentist who’s accused of murdering his wife Bianca on a 2016 hunting trip in Zambia and framing it as an accident to bank millions in insurance cash, testified in federal court Wednesday for the first time.
Rudolph vehemently denied accusations he killed his wife to receive a $4.8 million payout and finally be with his supposed lover, Lori Milliron, who faces an obstruction of justice charge herself.

Defense attorneys claim the ordeal was a tragic accident, with Bianca mistakenly shooting herself around 5 a.m. on Oct. 11, 2016, as she frantically packed a loaded gun into its case to return…
“We think the kind of reactions we’ve described are probably what could have happened on early Earth,” says Ramanarayanan Krishnamurthy.
The reaction generates the building blocks of proteins and DNA: amino acids and nucleic acids.
Four billion years ago, the Earth looked very different than it does today. It was devoid of life and covered by a vast ocean. Over the course of millions of years, life emerged in that primordial soup. For a long time, researchers have theorized how molecules came together to spark this transition. Now, scientists at Scripps Research have discovered a new set of chemical reactions that use ammonia, cyanide, and carbon dioxide—all thought to be common on the early Earth—to generate amino acids and nucleic acids, the building blocks of proteins and DNA.
“We’ve come up with a new paradigm to explain this shift from prebiotic to biotic chemistry,” says Ramanarayanan Krishnamurthy, PhD, and an associate professor of chemistry at Scripps Research. “We think the kind of reactions we’ve described are probably what could have happened on early Earth.” Krishnamurthy is the lead author of the new paper that was published in the journal Nature Chemistry on July 28, 2022.
In addition to giving scientists insight into the chemistry of the early Earth, the newly discovered chemical reactions are also useful in certain manufacturing processes. For example, in the generation of custom-labeled biomolecules from inexpensive starting materials.
Earlier this year, Krishnamurthy’s team showed how cyanide can enable the chemical reactions that turn prebiotic molecules and water into basic organic compounds required for life. This one worked at room temperature and in a wide pH range, unlike previously proposed reactions. The scientists wondered whether, under the same conditions, there was a way to generate amino acids, which are more complex molecules that compose proteins in all known living cells.
In cells today, amino acids are generated from precursors called α-keto acids using both nitrogen and specialized proteins called enzymes. Scientists have discovered evidence that α-keto acids likely existed early in Earth’s history. However, many researchers have hypothesized that before the advent of cellular life, amino acids must have been generated from completely different precursors, aldehydes, rather than α-keto acids, since enzymes to carry out the conversion did not yet exist. But that idea has led to debate about how and when the switch occurred from aldehydes to α-keto acids as the key ingredient for making amino acids.
After their success in using cyanide to drive other chemical reactions, Krishnamurthy’s group suspected that cyanide, even without enzymes, might also help turn α-keto acids into amino acids. Because they knew nitrogen would be required in some form, they added ammonia—a form of nitrogen that would have been present on the early Earth. Then, through trial and error, they discovered a third key ingredient: carbon dioxide. With this mixture, they quickly started seeing amino acids form.
“We were expecting it to be quite difficult to figure this out, and it turned out to be even simpler than we had imagined,” says Krishnamurthy. “If you mix only the keto acid, cyanide, and ammonia, it just sits there. As soon as you add carbon dioxide, even trace amounts, the reaction picks up speed.”
Because the new reaction is relatively similar to what occurs inside cells today—except for being driven by cyanide instead of a protein—it seems more likely to be the source of early life, rather than drastically different reactions, the scientists say. The research also helps bring together two sides of a long-standing debate about the importance of carbon dioxide to early life, concluding that carbon dioxide was key, but only in combination with other molecules.
In the process of studying their chemical soup, Krishnamurthy and his colleagues discovered that a byproduct of the same reaction is orotate, a precursor to nucleotides that make up DNA and RNA. This indicates that the same primordial soup, under the right conditions, could have given rise to a large number of the molecules that are required for the key elements of life.
“What we want to do next is continue probing what kind of chemistry can emerge from this mixture,” says Krishnamurthy. “Can amino acids start forming small proteins? Could one of those proteins come back and begin to act as an enzyme to make more of these amino acids?”

Water falls through holes in the ceiling at Caesar’s Palace in Las Vegas amid thunderstorms on July 28, 2022.Twitter / @SeanSable
Thunderstorms dumped heavy rain and kicked up high winds across central Nevada on Thursday, flooding the streets and casinos of Las Vegas. Lightning and small hail were also in the stormy mix that hit the popular summertraveldestination. More storm activity is expected Friday evening, from 6 to 8 p.m., with the chance for thunderstorms continuing into the weekend and next week.
“It’s all part of our monsoon season,” said Andy Gorelow, a forecaster with the National Weather Service office in Las Vegas. “This time of year is our best opportunity for thunderstorms. When we get a lot of this heat plus moisture during this time of year, it can produce thunderstorms.”
Search and rescue teams backed by the National Guard searched Friday for people missing in record floods that wiped out entire communities in some of the poorest places in America.Kentucky‘s governor said at least 16 people have died, a toll he expected to grow.
Gov. Andy Beshear said at least six children were among the victims.
“That’s hard,” the governor told reporters during a briefing Friday afternoon. “That’s even harder for those families and those communities, so keep praying. There’s still a lot of people out there, still a lot of people unaccounted for. We’re going to do our best to find them all.”
Beshear said earlier Friday the death toll was “going to get a lot higher.” He said later officials may be updating the number of fatalities “for the next several weeks.”

PLAINFIELD, Vt. —
Police have found the 69-year-old man who went missing while he was training his hunting dogs.
Officers say Ellsworth Spear, of Newbury, is back home safe after he went missing on Thursday afternoon.
Spears was located on Friday after he emerged from the woods near Pigeon Pond in Groton. He told officials that he became disoriented in the woods on Thursday night before being able to find his way out.
