The only freedom which deserves the name is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental or spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest.

Discovery of Omicron in New York deer raises concern over possible new variants

By Barbara Goldberg 

NEW YORK, Feb 8 (Reuters) - The discovery of the Omicron variant in white-tailed deer in New York has raised concerns that the species, numbering 30 million in the United States, could become hosts of a new coronavirus strain, a lead researcher said on Tuesday.

Blood and some nasal swab samples from 131 deer captured on New York's Staten Island revealed that nearly 15% had virus antibodies. The finding suggested that the animals had previous coronavirus infections and were vulnerable to repeated reinfections with new variants, researchers led by Pennsylvania State University scientists said.

“Circulation of the virus in an animal population always raises the possibility of getting back to humans, but more importantly it provides more opportunities for the virus to evolve into novel variants,” said Suresh Kuchipudi, a Penn State veterinary microbiologist.

"When the virus completely mutates, then it can escape the protection of the current vaccine. So we'd have to change the vaccine again," Kuchipudi said.

The discovery - the first time Omicron was detected in a wild animal - comes as a surge in COVID-19 infections fueled by the variant are abating among the U.S. human population.

While there is no evidence that animals are transmitting the virus to humans, most coronavirus infections were reported in species that had close contact with a person with COVID-19, according to the U.S. Department of Agriculture.

In August, the U.S. government said it found the world's first cases of COVID-19 in wild deer in Ohio, expanding the list of animals known to have tested positive for the disease.

The finding was based on samples collected from deer months before the heavily mutated variant Omicron emerged to replace the previously dominant Delta variant in people in countries around the world.

The USDA had previously reported COVID-19 in animals including dogs, cats, tigers, lions, snow leopards, otters, gorillas and minks.

Pfizer Beats Q4 Earnings Forecast, Sees $54 Billion In 2022 Covid Sales; Stock Slides

Pfizer said combined sales of its Covid vaccine and treatment drugs would rise to $54 billion this year, around half of its total projected revenues.

Martin Baccardax  February 8 , 2022

Pfizer Inc.  (PFE) - Get Pfizer Inc. Report posted better-than-expected fourth quarter earnings Tuesday, and forecast $54 billion in vaccine and treatment sales for the coming year, as it continues to outpace rivals in Covid treatment developments.

Pfizer said adjusted earnings for the three months ending in December were pegged at $1.08 per share, a 157% increase from the same period last year and well ahead of the Street consensus forecast of 87 cents. Group revenues, Pfizer said, surged 104% to $23.8 billion, a figure that fell just shy of analysts' estimates of an $24.1 billion tally.  

Looking into the 2022 financial year Pfizer said its sees adjusted earnings in the region of $6.35 to $6.65 per share, compared to the Refinitiv forecast of $6.69, and revenues of between $98 billion and $102 billion.

Sales of Pfizer's Comirnaty vaccine are expected to top $32 billion a $1 billion improvement from its prior forecast, while revenues from its recently-approved Covid pill Paxlovid are forecast to come in at $22 billion.

“In the early days of the COVID-19 pandemic, we committed to use all of the resources and expertise we had at our disposal to help protect populations globally against this deadly virus, as well as to offer treatments to help avoid the worst outcomes when infections do occur," said CEO Albert Bourla. "We put billions of dollars of capital on the line in pursuit of those goals, not knowing whether those investments would ever pay off."

"Now, less than two years since we made that commitment, we are proud to say that we have delivered both the first FDA-authorized vaccine against COVID-19 (with our partner, BioNTech  (BNTX) - Get BioNTech SE Report) and the first FDA-authorized oral treatment for COVID-19,” he added.  

Pfizer shares were marked 5.5% lower in early Tuesday trading following the earnings release to change hands at $50.26 each, a move that would trim the stock's six-month gain to around 9.3%.

Late last year, Pfizer said it will sell around 10 million of its Paxlovid treatment, which won Emergency Use Approval (EUA) by the U.S. Food & Drug Administration on December 22, to the United States Department of Health and Human Services.

At $530 per tablet, the cost is around 25% cheaper than the $700 price agreed with Merck & Co.  (MRK) - Get Merck & Co., Inc. Report in October to buy 1.7 million doses its 'molnupiravir' treatment of "mild-to-moderate Covid in adults who are at risk for progressing to severe forms of disease, or hospitalization.

SoftBank hit as profit, and Arm deal, collapse

By Sam Nussey 

TOKYO, Feb 8 (Reuters) - SoftBank Group Corp (9984.T) reported a 97% drop in quarterly profit and the collapse of a deal worth up to $80 billion to sell chip designer Arm on Tuesday, adding to pressure on the Japanese conglomerate to boost its sagging shares.

Masayoshi Son's investment giant reported a net profit of 29 billion yen ($251 million) in the October-December quarter versus a record 1.2 trillion yen a year earlier when its tech portfolio rallied.

SoftBank said it has dropped the sale of chip designer Arm to U.S. firm Nvidia (NVDA.O) due to regulatory hurdles. The scrapped deal marks a major setback for SoftBank's fund-raising plans as valuations again come under pressure from both growing investor caution and China's regulatory crackdown on tech firms.

"We were in the middle of a blizzard and the storm has not ended, it has got stronger," Son, SoftBank's founder and chief executive, told a briefing following the results.

Investors are growing cautious about tech firms promising future profits as central banks pare back stimulus.

SoftBank has also been whiplashed by exposure to China with shares of e-commerce giant Alibaba (9988.HK), in which SoftBank has a stake, droppingby a fifth last quarter.

SoftBank's Vision Fund unit reported an investment gain of 111.5 billion yen ($967 million), down from 1.4 trillion yen a year earlier.

----SoftBank launched a 1 trillion yen buyback in November. Group shares closed down 0.9% ahead of the earnings and have lost about half their value since highs hit in March 2021.

Many SoftBank portfolio companies are trading below their listing price, with office-sharing firm WeWork (WE.N), ride hailer Grab and used-car platform Auto1 all down last quarter.

Peloton co-founder steps down after rough ride

The co-founder of Peloton is stepping down as chief executive after an extended streak of tumult at the exercise and treadmill company.

Barry McCarthy, who served as CFO at Spotify as well as at Netflix, will take over the CEO position held by John Foley, effective Wednesday. McCarthy will also have a seat on the board.

Foley will become executive chair at Peloton Interactive Inc.

Peloton had been the subject in media reports this week of a potential takeover target by either Amazon and Nike. The developments Tuesday deflated hopes for such a deep-pocketed buyer and shares of Peloton slumped 7% before the opening bell.

The company’s shares have been on a roller-coaster ride since the pandemic began. They surged more than 400% in 2020 as COVID-19 forced lockdowns and shifted the workout trend from the gym to the home.

In 2021, the shares gave back nearly all of those gains as businesses reopened and people started heading back to gyms. The stock fell further this year amid reports the company would cut back production of bikes and treadmills to try to offset a decline in sales.

There was also a demand late last month from activist investor Blackwells Capital that Peloton remove Foley as CEO and that it consider selling the company amid waning consumer demand.

Peloton also announced 2,800 job cuts globally, including approximately 20% of corporate jobs at the New York City company. The instructors who lead interactive classes for Peloton will not be included in cuts, nor will the content that the company relies on to lure users.

Peloton is looking to reduce its planned capital expenditures for this year by about $150 million. The restructuring program is expected to result in approximately $130 million in cash charges related to severance and other exit and restructuring activities and $80 million in non-cash charges. The majority of the charges will be recorded in fiscal 2022.

The company anticipates at least $800 million in annual cost savings once its actions are fully implemented.

India struggles to contain vegoil prices as Indonesia restricts exports

Tue, February 8, 2022, 10:03 AM

MUMBAI (Reuters) - India's attempts to lower edible oil prices ahead of important state elections have been ruined by a spike in global palm oil prices to record highs after Indonesia, the world's biggest supplier, moved restrict exports.

Mindful of an electorate that is highly sensitive to food price inflation, India's government tried to rein in domestic prices by reducing import taxes, imposing stockpile limits and suspending futures trading in edible oils and oilseeds.

Those efforts initially yielded some success.

But as India imports two-thirds of its edible oils, the benefits of the duty cut and other measures have been virtually erased by the surge in global prices after Indonesia ordered producers to sell 20% of their sales to the domestic market to cool local cooking oil prices.

"Indonesia's move has complicated India's efforts to bring down prices," said B.V. Mehta, executive director of Mumbai-based Solvent Extractors’ Association of India (SEA).

Spot prices of palm oil, the most consumed edible oil in the country, have risen more than 12% so far in 2022 to 1,228 rupees per 10 kg after hitting a record high of 1,280.75 rupees in May 2021.

The price of rival oils such as soyoil and sunflower oil jumped as buyers scrambled to replace lost palm oil volumes, increasing import bills for the world's biggest edible oil importer and making it difficult for New Delhi to rein in costs for consumers.

Previously, palm oil was by far the most imported oil in India, but "at the current price level there is no advantage to buy palm oil," an Indian refiner, who declined to be named, said.

Crude palm oil (CPO) is being offered at around $1,450 a tonne, including cost, insurance and freight (CIF), in India for March shipments, compared with $1,490 for crude soybean oil and $1,455 for crude sunflower oil, traders said.

Global vegetable oil prices surge, hitting cost-sensitive buyers like India https://tmsnrt.rs/3GxHV4v

A year ago, palm oil was trading at a discount of around $100 and $250 per tonne to soyoil and sunflower oil respectively, both regarded as better quality than palm oil.

India's retail food price inflation rose to 4.05% in December, and analysts expect it to stay on an upward trend in coming months.

Cooking Oils Surge Is Sign Food Inflation Can Go Even Higher

Mon, February 7, 2022, 5:24 AM

(Bloomberg) -- A fresh spike in cooking oil prices is increasing concerns that global food costs are heading for a record as drought curbs production in South America, a labor shortage stymies output in Malaysia and Indonesia limits exports to safeguard domestic supplies.

Palm oil, the world’s most consumed cooking oil, climbed to yet another intraday record in Kuala Lumpur on Monday, buoyed by shipment restrictions in top grower Indonesia and a chronic worker shortage in Malaysia’s plantations.

Soybean oil traded near the highest since June, while soybeans, from which the oil is derived, jumped to the strongest since May. Heat and drought have led to repeated reductions in estimates for soybean crops in top grower Brazil and in Argentina. That may well be reflected in lower predictions for global supplies in the monthly report from the U.S. Department of Agriculture on Wednesday.

Global food costs climbed nearer to a record in January, according to the latest data from the United Nations, because of more expensive vegetable oils and dairy. The most recent increase in cooking oil prices could push the monthly food index to a record when it is published again in early March. Rising fertilizer costs because of higher energy markets may also bolster food prices.

The rally on Monday followed the return of Chinese investors after a week-long Lunar New Year holiday. Soybean meal futures in Dalian climbed by the daily limit, while palm oil prices jumped to the highest since 2008.

----The cost of soybeans in Brazil jumped over the past month as forecasts for the current harvest were slashed due to excessive heat and drought.

The people fighting price rises by trying to buy nothing

Tue, February 8, 2022, 9:59 AM

Prices in the US soared 7% last year - the biggest annual increase in nearly four decades. Now US consumers - whose spending powers the world's largest economy - are starting to signal they have had enough.

"I find now, that I'm constantly tracking the cost of certain items," Sevan Tavoukdjian says. "It's changed which items I buy."

The 34-year-old actor moved into his own apartment in New York City last month and when he saw how much it would cost to furnish it, he was shocked at the prices being charged.

So, he scrapped plans to buy furniture and instead sent a message to his neighbourhood “Buy Nothing” Facebook group, where people offer unwanted items for free.

“I thought, 'I’m going to go broke just buying the basic necessities'," he says. “I would have loved to buy a new couch, but the prices are like, ‘Well – No’.”

The average American family had to spend roughly $3,500 (£2,600) more last year than in 2020 for the same goods and services due to inflation, according to researchers at the University of Pennsylvania Wharton School.

Housing costs were up 4.2%, grocery bills jumped 6.3% and clothing prices were 5.8% higher. Living and dining furniture - like Mr Tavoukdjian was seeking - saw one of the biggest spikes, rising more than 17%.

But salaries have not kept up with the increases, pushing people to forego purchases, substitute cheaper alternatives, or - like Sevan - hunt for something free.

The situation has driven a surge in activity on neighbourhood exchanges such as the Buy Nothing Project, the group Mr Tavoukdjian turned to when he wanted to furnish his apartment, building on growth since the start of the pandemic.

Membership in the group has more than doubled over the past two years to more than 5.3 million globally. It recently added an app to cope with demand.

At Freecycle, a similar site where participants typically offer up some 20,000 items each day, the number of posts each day has increased by about 15% in recent months, driven by the financial concerns, founder, Deron Beal says.

Vitamin D could be a piece of COVID-19's 'complex puzzle,' Israeli scientists say, after a new study finds a link between deficiency and severe illness

Mon, February 7, 2022, 4:51 PM

Israeli scientists said they found "striking" differences in the chances of getting seriously ill from COVID-19 when they compared patients who had sufficient vitamin D levels prior to contracting the disease with those who didn't.

A study published on Thursday in the research journal PLOS One found that about half of people who were vitamin D deficient before getting COVID-19 developed severe illness, compared to less than 10% of people who had sufficient levels of the vitamin in their blood.

We know vitamin D is vital for bone health, but its role in protecting against severe COVID-19 is less well established.

The latest research was the first to examine vitamin D levels in people prior to them contracting COVID-19, the study authors said.

Dr. Amiel Dror, a study author and physician at the Galilee Medical Center, said of the findings, "We found it remarkable, and striking, to see the difference in the chances of becoming a severe patient when you are lacking in vitamin D compared to when you're not," The Times of Israel reported.

The findings come from 253 people admitted to Galilee Medical Center in Nahariya, Israel, between April 7, 2020, and February 4, 2021 — a period before the highly infectious Omicron variant emerged.

Dror said the findings suggested that vitamin D helped bolster the immune system to deal with viruses that attack the respiratory system.

The research doesn't prove that vitamin D protects against COVID-19 and isn't a green light to avoid vaccines and take vitamins instead. Vaccines cut the risk of Omicron hospitalization, particularly after a booster, by up to 90%, the UK Health Security Agency said.

Most vitamin D comes from direct sunlight on the skin. It's also found in foods such as fatty fish, mushrooms, and egg yolks and in supplements.

Vitamin D levels of more than 20 nanograms per milliliter are considered sufficient for most people, said the Centers for Disease Control and Prevention — which is the benchmark used by the researchers from Bar-Ilan University and Galilee Medical Center.

Research compiled before the emergence of COVID-19 and published in The Lancet found that vitamin D cut the risk of other respiratory infections, compared with dummy drugs.

----Despite the new data from Israel, we still don't know if low vitamin D levels cause people with COVID-19 to develop serious disease.

Underlying conditions that reduce vitamin D can also make people more vulnerable to severe COVID-19, for example.

The Israeli researchers cautioned that vitamin D was "one piece of the complex puzzle" underlying severe COVID-19, in addition to comorbidities, genetic predisposition, dietary habits, and geographic factors.

"Our study warrants further studies investigating if and when vitamin D supplementation among vitamin D deficient individuals in the community impacts the outcome of an eventual COVID-19 episode," they said.

CDC adds Japan and Israel to 'very high' COVID risk category, warns travelers to 'avoid' 130+ countries

Tue, February 8, 2022, 1:03 AM

Federal health officials are warning Americans to avoid Japan, Israel and more than 130 other countries – regardless of vaccination status – because of high counts of COVID-19 cases.

The Centers for Disease Control and Prevention on Monday moved Japan, Israel, Cuba, Armenia, Libya, Oman and the Democratic Republic of the Congo to its level 4 category, the highest travel health notice tier, for their “very high” COVID-19 risk.

“Avoid travel to these destinations,” the CDC says on its website. “If you must travel to these destinations, make sure you are fully vaccinated before travel.”

Larger countries are considered to have very high COVID-19 risk when they report more than 500 cases of new cases per 100,000 people over the past 28 days.

CDC LEVEL 4 WARNING: The CDC warns US travelers to avoid more than 100 countries. Do people care?

Level 4 now includes 133 countries, including popular destinations like Canada, Mexico, the Bahamas and the United Kingdom.

Other changes to the CDC's travel health notice page include:

Bangladesh, Montserrat and South Africa are now listed as level 3 destinations, with "high" COVID-19 risk. The CDC says travelers should be fully vaccinated before traveling to these destinations and suggests unvaccinated travelers avoid nonessential travel there.

•Pakistan is considered to have "moderate" COVID-19 risk after moving to level 2 on Monday. The CDC says travelers should be fully vaccinated before traveling to level 2 destinations and warns unvaccinated travelers who are at increased risk for severe illness from COVID-19 to avoid nonessential travel to these areas.

Chinese scientists say new highly accurate virus test gives results within minutes

Issued on: 08/02/2022 - 08:02

Beijing (AFP) – Chinese scientists say they have developed a new coronavirus test that is accurate as a PCR lab test but gives results within four minutes.

Polymerase chain reaction (PCR) tests are widely considered the most accurate and sensitive for the virus that causes Covid-19, but they usually take several hours.

Some countries have experienced severe backlogs in the face of heavy testing demand, fuelled by the explosive spread of the highly transmissible Omicron variant.

Researchers from Fudan University in Shanghai say they have a solution.

In a peer-reviewed article published Monday in the journal Nature Biomedical Engineering, the team said their sensor -- which uses microelectronics to analyse genetic material from swabs -- can reduce the need for time-consuming Covid lab tests.

We implemented an electromechanical biosensor for the detection of SARS-CoV-2 into an integrated and portable prototype device, and show that it detected (virus RNA) in less than four minutes," the team said in the paper, referring to the official name of the Covid pathogen.

The researchers said their method offers speed, ease of operation, high sensitivity and portability.

Their trial involved taking samples from 33 people in Shanghai who were infected with the coronavirus, with PCR tests conducted in parallel.

The results from their method were a "perfect" match with the PCR tests, according to the article.

Their study involved testing the new method on 54 samples, which included people with fever who did not have the coronavirus, those with influenza, and healthy volunteers.

Those cases did not yield any false positives, the team said.

The Fudan researchers said that once developed, their testing device can be used for quick testing in a variety of situations, including airports, health facilities and "even at home".

PCR tests are not only slow, but they also require lab infrastructure that can be limited in many countries, reducing the number of cases that can be handled each day.

And while rapid diagnostic tests have now become available in many parts of the world, they are generally less accurate.

China is one of the world's biggest makers of coronavirus test kits.

According to customs data, it exported $1.6 billion worth of test kits in December, a 144 percent increase from the previous month.

Observation of quantum transport at room temperature in a 2.8-nanometer CNT transistor

Semiconductor nanochannels created within metallic CNTS by thermally and mechanically altering the helical structure

Date:  February 3, 2022

Source:  National Institute for Materials Science, Japan

Summary:  A research team has developed an in situ transmission electron microscopy (TEM) technique that can be used to precisely manipulate individual molecular structures. Using this technique, the team succeeded in fabricating carbon nanotube (CNT) intramolecular transistors by locally altering the CNT's helical structure, thereby making a portion of it to undergo a metal-to-semiconductor transition in a controlled manner.

An international joint research team led by the National Institute for Materials Science (NIMS) has developed an in situ transmission electron microscopy (TEM) technique that can be used to precisely manipulate individual molecular structures. Using this technique, the team succeeded in fabricating carbon nanotube (CNT) intramolecular transistors by locally altering the CNT's helical structure, thereby making a portion of it to undergo a metal-to-semiconductor transition in a controlled manner.

Semiconducting CNTs are promising as the channel material for energy-efficient nanotransistors which may be used to create microprocessors superior in performance to currently available silicon microprocessors. However, controlling the electronic properties of CNTs by precisely manipulating their helical structures has been a major challenge.

This joint research team succeeded for the first time in controllably manipulating CNTs' electronic properties by locally altering their helical structures using heat and mechanical strain. Using this technique, the team was then able to fabricate CNT transistors by converting a portion of a metallic CNT into a semiconductor, where the semiconductor nanochannel was covalently bonded to the metallic CNT source and drain. The CNT transistors, with the channel as short as 2.8 nanometers in length (1 nm = one billionth of a meter), exhibited coherent quantum transport at room temperature -- wave-like electron behavior usually observed only at extremely low temperature.

The molecular structure manipulation technique developed in this research may potentially be used to fabricate innovative nanoscale electronic devices. The team plans to use this technique to engineer material structures with atomic-level precision to fabricate electronic and quantum devices composed of individual atomic structures or molecules.
