AMSTERDAM/LONDON
(Reuters) - Germany, France and other European nations announced plans to
resume using AstraZeneca’s COVID-19 vaccine on Thursday after EU and British
regulators moved to shore up confidence in the shot, saying its benefits
outweigh the risks.
Reports of rare brain blood clots
had prompted more than a dozen nations to suspend use of the shot, the latest
challenge for AstraZeneca’s ambition to produce a “vaccine for the world”, as
the global death toll from the coronavirus passes 2.8 million.
The European Medicines Agency’s
(EMA) “clear” conclusion following an investigation into 30 cases of unusual
blood disorders was that the vaccine’s benefits in protecting people from
coronavirus-related death or hospitalisation outweighs the possible risks,
though it said a link between blood clots in the brain and the shot could not
be definitively ruled out.
“This is a safe and effective
vaccine,” EMA director Emer Cooke told a briefing. “If it were me, I would be
vaccinated tomorrow.”

UK vaccine roll-out to be slower
than hoped, deliveries to pick up from May

LONDON
(Reuters) - Britain said on Thursday that global supply bumps meant its vaccine
roll-out would be slower than hoped in coming weeks but it expected deliveries
to increase again in May, June and July.
British health officials warned on
Wednesday that the world’s fastest big economy roll-out of the vaccine would
face a significant reduction in supplies from March 29.
Pfizer Inc and AstraZeneca Plc said
their delivery schedules had not been impacted, and Housing Secretary Robert
Jenrick refused to be drawn on whether the issue was due to a problem with
supply from India.
“We have less supply than we might
have hoped for the coming weeks but we expect it to increase again later,”
Jenrick told the BBC.
“The vaccine roll-out will be
slightly slower than we might have hoped but not slower than the target,” he
said. “We have every reason to believe that supply will increase in the months
of May, June and July.”
Britain is on track to have given a
first shot to half of all adults in the next few days, making it one of the
fastest countries to roll out a vaccine.
So far
25.27 million people in the United Kingdom have had a vaccine, around 48% of
adults, and Jenrick said Britain remained on track to have vaccinated priority
groups by April 15 and all adults by the end of July.

African Union says benefits
outweigh risks of AstraZeneca COVID shot
March 18, 2021 10:34 AM
ADDIS ABABA (Reuters) - The African
Union said on Thursday that it considers that the benefits of AstraZeneca’s
COVID-19 vaccine outweigh the risks and recommended that vaccinations continue
across the continent.
The announcement came a day after
the World Health Organization backed the vaccine and as more than a dozen
European countries have suspended the use of it amid concerns over the risk of
blood clots.
John Nkengasong, director of the
Africa Centers for Disease Control and Prevention, told a news conference that
the “benefits still outweigh the risks” and that countries should “move
forward” with the vaccination.
AstraZeneca said on Sunday a review
of safety data of more than 17 million people vaccinated in the United Kingdom
and European Union with its vaccine had shown no evidence of an increased risk
of blood clots.
The head of the continent’s disease
control body said that adverse reactions would be monitored and reported for
future assessments on the vaccine.
Some African countries have already
suspended use of the AstraZeneca vaccine.
On Friday the Democratic Republic of
Congo delayed the rollout of the shot, citing the suspension of the use of the
shots by European countries.
Many African states expect to
receive AstraZeneca shots from the COVAX Facility, a global vaccine allocation
plan co-led by the World Health Organization and partners including the Gavi
vaccines alliance, which will be delivering vaccines for free to some low and
lower-middle-income countries.
The
European Medicines Agency is investigating reports of 30 cases of unusual blood
disorders out of 5 million people who got the AstraZeneca vaccine in the EU. It
said it has so far found no causal link.

Transparent solar cells don't
steal light from greenhouse crops
By Michael Irving March 17, 2021
Advances
in transparent solar
cells mean that soon we might be able to install them into
windows and greenhouses. But in the latter case, would they deprive plants of
vital sunlight? To find out, researchers at North Carolina State University
grew lettuce under various wavelengths of light, and found that the plants did
just fine.
Organic
solar cells are emerging as a viable system for renewable energy, thanks to a
number of advantages. They can be more flexible than other technologies, be
made transparent or semi-transparent, and the wavelengths of light they harvest
can be adjusted.
In theory, that could make them perfect for embedding into
greenhouse roofs. There, these organic solar cells could capture certain
wavelengths of light while still allowing some of it to pass through to the
plants below. In a previous
study , the NC State team investigated how much energy this kind of setup
could produce, and found that it could be enough to make greenhouses energy
neutral.
But of course there’s one big piece of that puzzle missing
– nobody asked the plants how it affected them. So that was the focus of the
new work.
The researchers grew groups of red leaf lettuce in
greenhouses for 30 days, which took them up to full maturity. The different
groups were all exposed to the same growing conditions, such as temperature,
water, fertilizer and CO2 concentration. The only difference was
light.
The lettuces were split into four groups – a control group
that received regular white light, and three experimental groups that grew
under light passed through different filters. These changed the ratio of red to
blue light that they received, to mimic wavelengths that would be blocked by
transparent solar cells.
Then the team monitored several markers of plant health,
including number and size of leaves, weight, how much CO2 they
absorbed and the levels of antioxidants they contained. And perhaps
surprisingly, it turns out that the lettuces thrived regardless of what type of
light they received.
“Not only did we find no meaningful difference between the
control group and the experimental groups, we also didn’t find any significant
difference between the different filters,” says Brendan O’Connor,
co-corresponding author of the study.
The team says that it’s currently working on testing the
effects of blocking different wavelengths of light on other crops, like
tomatoes.
The research was published in the journal Cell Reports Physical Science .

Another weekend and which nuclear power leader is in
President Biden’s sights for a public insult? After the tumultuous Trump
presidency, President Biden seems to want to escalate the Trump tensions. If he does, I wonder how the markets will
react. Have a great Spring/Autumn Equinox weekend everyone.
Drops the wind and stops the mill;
Turbot is ambitious brill;
Gild the farthing if you will,
Yet it is a farthing still.
