China allocates 200 million yuan in disaster relief funds after earthquake in northwest China's Gansu

The Ministry of Finance and the Ministry of Emergency Management on Tuesday have urgently allocated 200 million yuan ($28 million) in disaster relief funds to northwest China’s Gansu and Qinghai provinces. This funding will support local earthquake relief efforts and ensure the safety of people's lives and property, minimizing the impact and losses caused by the disaster, China Media Group (CMG) reported.

China is stepping up rescue and relief efforts to ensure the safety of people's lives and property after a 6.2-magnitude earthquake shook Jishishan County in northwest China's Gansu Province at midnight Monday.

The State Council has sent a working group to the stricken regions to help guide relief work. Gansu and Qinghai provinces have organized relief support with immediate allocation of relief supplies such as camps and folding beds to impacted areas.

Relief supplies were immediately redeployed from nearby areas, with supplies gradually arriving to impacted communities, China’s National Development and Reform Commission (NDRC) told a press conference on Tuesday.

The NDRC has activated emergency response mechanism to ensure energy, electricity, and essential supplies. Efforts are being made to repair damaged power facilities and provide emergency power supply. Food and material reserves are being allocated for disaster relief, a spokesperson from the NDRC said.

The first shipment of 46,100 emergency relief supplies from central and provincial level have been dispatched to the disaster-stricken areas, including cotton tents, quilts, mattresses, folding beds, cotton shoes, and stoves, according to Gansu provincial grain and material reserve bureau. The bureau has also obtained 15 tons of flour for emergency supply in Jishishan.

The State Council's earthquake relief headquarters and the Ministry of Emergency Management have upgraded the national earthquake emergency response to Level II.

At present, the earthquake has led 105 deaths in Gansu and 11 deaths in Qinghai, with damaging basic infrastructure such as water, electricity, transportation, and communications, Xinhua News Agency reported.

Rescue and relief efforts are progressing in an orderly manner, including hazard inspections, evacuation and resettlement of residents, and repair of damaged facilities, China Media Group reported.

Pan Bing won the men's title for China at 1990 and 1994 Asian Games.

Another Chinese player Wu Yibing, silver medalist at Jakarta 2018, suffered an early exit after a shock third-round defeat on Tuesday.

U.S. will withdraw from climate pact, Trump announces

President Donald Trump announced on June 1 that the United States will pull out of the Paris climate accord.

In signing the 2015 Paris agreement, the United States, along with 194 other countries, pledged to curb greenhouse gas emissions to combat global warming. But Trump — who has called climate change a “hoax” despite scientific evidence to the contrary — promised during his campaign that he would withdraw from the Paris accord.

“The agreement is a massive redistribution of the United States’ wealth to other countries,” Trump said. “As of today, the United States will cease all implementation of the nonbinding Paris accord and the draconian financial and economic burdens [it] imposes on our country.” This includes making further payments to the Green Climate Fund, set up to help developing countries battle and cope with climate change. The United States has already paid $1 billion of the $3 billion it pledged to the fund.

Trump did leave the door open to reentering the Paris accord under revised terms or signing an entirely new climate agreement.

Neutrino experiment may hint at why matter rules the universe

A new study hints that neutrinos might behave differently than their antimatter counterparts. The result amplifies scientists’ suspicions that the lightweight elementary particles could help explain why the universe has much more matter than antimatter.

In the Big Bang, 13.8 billion years ago, matter and antimatter were created in equal amounts. To tip that balance to the universe’s current, matter-dominated state, matter and antimatter must behave differently, a concept known as CP, or “charge parity,” violation.

In neutrinos, which come in three types — electron, muon and tau — CP violation can be measured by observing how neutrinos oscillate, or change from one type to another. Researchers with the T2K experiment found that muon neutrinos morphed into electron neutrinos more often than expected, while muon antineutrinos became electron antineutrinos less often. That suggests that the neutrinos were violating CP, the researchers concluded August 4 at a colloquium at the High Energy Accelerator Research Organization, KEK, in Tsukuba, Japan.

T2K scientists had previously presented a weaker hint of CP violation. The new result is based on about twice as much data, but the evidence is still not definitive. In physicist parlance, it is a “two sigma” measurement, an indicator of how statistically strong the evidence is. Physicists usually require five sigma to claim a discovery.

Even three sigma is still far away — T2K could reach that milestone by 2026. A future experiment, DUNE, now under construction at the Sanford Underground Research Laboratory in Lead, S.D., may reach five sigma. It is worth being patient, says physicist Chang Kee Jung of Stony Brook University in New York, who is a member of the T2K collaboration. “We are dealing with really profound problems.”

A new tool could one day improve Lyme disease diagnosis

A new testing method can distinguish between early Lyme disease and a similar tick-borne illness, researchers report. The approach may one day lead to a reliable diagnostic test for Lyme, an illness that can be challenging to identify.

Using patient blood serum samples, the test accurately discerned early Lyme disease from the similar southern tick‒associated rash illness, or STARI, up to 98 times out of 100. When the comparison also included samples from healthy people, the method accurately identified early Lyme disease up to 85 times out of 100, beating a commonly used Lyme test’s rate of 44 of 100, researchers report online August 16 in Science Translational Medicine. The test relies on clues found in the rise and fall of the abundance of molecules that play a role in the body’s immune response.
“From a diagnostic perspective, this may be very helpful, eventually,” says Mark Soloski, an immunologist at Johns Hopkins Medicine who was not involved with the study. “That’s a really big deal,” he says, especially in areas such as the mid-Atlantic where Lyme and STARI overlap.

In the United States, Lyme disease is primarily caused by an infection with the bacteria Borrelia burgdorferi, which is spread by the bite of a black-legged tick. An estimated 300,000 cases of Lyme occur nationally each year. Patients usually develop a rash and fever, chills, fatigue and aches. Black-legged ticks live in the northeastern, mid-Atlantic and north-central United States, and the western black-legged tick resides along the Pacific coast.

An accurate diagnosis can be difficult early in the disease, says immunologist Paul Arnaboldi of New York Medical College in Valhalla, who was not involved in the study. Lyme disease is diagnosed based on the rash, symptoms and tick exposure. But other illnesses have similar symptoms, and the rash can be missed. A test for antibodies to the Lyme pathogen can aid diagnosis, but it works only after a patient has developed an immune response to the disease.

STARI, spread by the lone star tick, can begin with a rash and similar, though typically milder, symptoms. The pathogen responsible for STARI is still unknown, though B. burgdorferi has been ruled out. So far STARI has not been tied to arthritis or other chronic symptoms linked to Lyme, though the lone star tick has been connected to a serious allergy to red meat (SN: 8/19/17, p. 16). Parts of both ticks’ ranges overlap, adding to diagnosis difficulties.

John Belisle, a microbiologist at Colorado State University in Fort Collins, and his colleagues had previously shown that a testing method based on small molecules related to metabolism could distinguish between early Lyme disease and healthy serum samples. “Think of it as a fingerprint,” he says. The method takes note of differences in the abundancy of metabolites, such as sugars, lipids and amino acids, involved in inflammation.
In the new work, Belisle and colleagues measured differences in the levels of metabolites in serum samples from Lyme and STARI patients. The researchers then developed a “fingerprint” based on 261 small molecules to differentiate between the two illnesses. To determine the accuracy, they tested another set of samples from patients with Lyme and STARI as well as those from healthy people. “We were able to distinguish all three groups,” says Belisle.

As a diagnostic test, “I think the approach has promise,” says Arnaboldi. But more work will be necessary to see if the method can sort out early Lyme disease, STARI and other tick-borne diseases in patients with unknown illnesses.

Having information about the metabolites abundant in STARI may also help researchers learn more about this disease, says Soloski. “This is going to spur lots of future studies.”
